Mario (universe)

The Super Mario universe' (, Mario) (referred to as the Super Mario Bros. series prior to Super Mario Land) refers to the ' series' collection of characters, stages, and properties that hail from Nintendo's expansive and highly successful Mario'' video game franchise. The Mario universe is Nintendo's flagship franchise, and it is flat-out the most successful game franchise in global sales and in history (although the franchise has found even greater success when counting non-game media). The Mario universe is a franchise of fantasy video games, and the most popular games are the fantasy adventure platform games called the Super Mario games. Mario himself is Nintendo's mascot and is considered the most famous video game character in the world. Mario and his brother Luigi, along with their many friends and nemeses, have appeared in dozens upon dozens of Nintendo's video games, many of them being best-sellers and several of which are considered some of the greatest games ever released.

As a direct result, there are more Mario-themed characters, items, and properties to be found in the Smash Bros. series than any other Nintendo franchise, not the least of which are fourteen distinctive playable characters who originated from the series between the original Super Smash Bros. and Super Smash Bros. Ultimate: Mario, his alter-ego Dr. Mario, Luigi, Bowser, Princess Peach (who has Toad as an attack), Rosalina (who uses Lumas to attack), Bowser Jr. (who has the Koopalings as alternate costumes), Daisy (who functions as a clone of Peach), and even the Piranha Plant. The Mario universe is so expansive, in fact, that Donkey Kong, Yoshi and Wario are considered stars of their own sub-universes: Donkey Kong, Diddy Kong and King K. Rool from the universe, Yoshi from the  universe, and Wario from the  universe. The universe is also a sub-universe of the Mario universe, although no playable characters hail from it. It is the most heavily represented universe in the Super Smash Bros. series, by far, with the highest trophy, sticker, and item count in the series, with the total amount of playable characters falling second to the universe (nine to ten if Pokémon Trainer is counted as three separate characters).

Franchise description
During development of , Shigeru Miyamoto created a protagonist initially titled, before being renamed to "Jumpman." Due to the unprecedented success of this game, the character immediately became a recognizable icon of the early days of gaming, and made several more appearances afterwards. In the 1982 follow-up , the character was officially renamed to Mario, named after Nintendo of America landlord Mario Segale. This is also one of the few instances Mario is portrayed as an antagonist, with the titular Donkey Kong Jr. attempting to save his father from capture. Mario would get a starring role in 1983 with the game  that codified many of the elements that defined the franchise afterwards. This game was the first appearance of Mario's brother Luigi, established that they were brothers who dealt with pipes, and fought against enemies like bugs, turtles, and fire balls. Mario would make other appearances around this time on television, various titles, and guest appearances in games like  and Golf.

A sequel to Mario Bros. was put into development, this time as an exclusive to the then two year old Famicom home console. Miyamoto realized that quick bursts of content would not be enough for at-home play, and attempted to make a more substantial experience, which included long, intricate levels with branching paths and secrets. Partially inspired by with its vertical scrolling gameplay, this game would have smooth horizontal scrolling gameplay. This game would release in 1985 release of , and quickly became a top seller for the system. When the Famicom was released outside of Japan as the Nintendo Entertainment System, Super Mario Bros. was bundled with the first circulation of consoles. The game is often labeled as the single most influential video game involved in not just the popularization of the side-scrolling game genre, but the direction the video game industry itself would take following the 1983 crash, and is often described as the game that began the modern era of video games. Almost all of the game's aspects have been praised on separate occasions; the precise controls, creative power-up system, and well-tuned speed and momentum mechanics came into play against a varied set of level-design obstacles and distinctive enemies, and Mario's whimsical quest through his newly established setting, the Mushroom Kingdom, to rescue his love interest Princess Toadstool from the dragon turtle-like Bowser was timeless. The game became the best-selling video game in history a record it held for over twenty years before being surpassed by in 2008.

The Super Mario franchise indisputably became Nintendo's foremost property immediately, and Mario himself earned a permanent position as the company's mascot. It became a custom to release a steady stream of Mario-related titles for each and every Nintendo console and handheld launched in the company's history, and even some non-Nintendo developed systems. To date, nearly 300 games feature Mario characters in some way. Many entries into the series enjoyed a high level of success and are often among the top selling titles on any given system, mostly due to brand recognition, but also for the most part by being genuinely polished and innovative experiences that stand the test of time. The early NES and SNES Mario 2D platformers would codify what would make up games of that style, which was further innovated by  bring the concept of a level editor to the mainstream. The game ' would define how to move in 3D space with a free roaming camera and large levels to explore and find secrets, which were followed up by games like ', ', and '. the ' franchise would lay the foundation for cart racing games, and the ' series would lay the foundation for party games. Other notable entries include the game ', which itself inspired other Mario-centric role playing games such as the ' and ' series, Dr. Mario as its own series of puzzle games, and a host of sports games like ', ' ' series.

Outside of videogames, Mario continues to be a juggernaut in merchandising. Mario's face and name have been featured on countless products including toys, table top games, household items and stationery, apparel, collectible items, feature films, animated series, print media like books and manga, and theme parks. Mario was even used to promote the Olympic games in 2016 and 2020. The Mario brand is estimated to be worth over 36 billion dollars in net revenue.

The Mario setting itself most often stars Mario, a free-spirited and heroic man with strong jumping abilities who is, by this point at least, a celebrity in the colorful and cartoon-like. Mario is often accompanied by his taller and more cowardly brother Luigi, who is occasionally mocked in-universe for being less famous than his sibling, but also goes on a few adventures of his own. His love interest and the ruler of the kingdom, Princess "Peach" Toadstool, regularly gets taken away by Mario's trouble-making arch-nemesis, Bowser, who is depicted as a menacing figure and/or a comedic one depending on the game. The most common setup for a Mario game is that Mario goes on an obstacle-laden quest to defeat Bowser and save Peach. Mario games rarely devote focus to lore or characterization; Mario, his world, and the established personalities that are his numerous allies and enemies represent Nintendo's primary "tileset" for creating colorful games of various genres that prioritize the quality of the gameplay itself, and Mario games sometimes satirize some conventions in video games like being self-aware of their own game logic and intentionally breaking them to subvert expectations.

The Mario franchise is so big, and its side characters so thoroughly established, that several of these characters are the stars of their own semi-regular releases. Donkey Kong, of which the Mario franchise is technically a spin-off, ironically was demoted to a spin-off and has starred alongside a simian supporting cast of his own in the  series that, for a time, were primarily handled by British company Rareware. A pet-like dinosaur companion for Mario named Yoshi was introduced in the SNES launch title Super Mario World, and has been the focus of the self-titled  series. Mario's timid and cowardly brother Luigi would occasionally receive a starring role of his own, primarily with the acclaimed  series. A mischievous anti-hero equivalent to Mario who debuted in ' for the Game Boy, Wario, took over the Mario Land series with the renamed ' series and  series that deliver a more outward parody of video game trends. Princess Peach has also occasionally taken the spotlight with the Nintendo DS game  and an upcoming game to release in 2024.

In Super Smash Bros.
Being Nintendo's biggest franchise, the Mario universe understandably outnumbers every other universe in Smash 64. It is one of two universes to have two playable characters, and is the only one to have two stages, and a boss character. and also appear as playable characters with their own stages, however they are represented as different universes.

Fighters

 * MarioIcon(SSB).png (Starter): Mario is the mascot of Nintendo, and probably the most well-known video game character in the world. He first appeared in the arcade game Donkey Kong as the main protagonist, and since then, has appeared as the main hero in the Mario franchise. He has appeared in many Nintendo games spanning a large variety of genres. In almost every game that he is playable in, he is the most balanced character. This is also true in Smash 64, as he acts as a balanced starting character. Mario's appearance and moves are based of his appearance in Super Mario 64. An exception is his neutral special, which is his iconic Fireball attack from his sidescroller games. His up special is Super Jump Punch, a rising, multi-hitting punch based on Mario jumping and hitting a coin block. His down special is Mario Tornado, a spinning attack loosely on the from Super Mario World.
 * LuigiIcon(SSB).png (Unlockable): Luigi is Mario's younger, lankier twin brother who acts as the co-star and deuteragonist of the Mario franchise. He first appeared in the arcade game Mario Bros. as a green palette swap of Mario. Since then, he has started to gain his own personality and abilities. In Smash 64, he appears as an unlockable character. His appearance is based off of Mario Kart 64, which was his last major appearance. Luigi is a clone character of Mario, fittingly enough. However, he possesses his trademark superior jump height and inferior traction, and some of his moves have unique attributes. While his neutral special is also a Fireball attack, Luigi's are green, and they travel in a straight line, unaffected by gravity. His up special is also Super Jump Punch, but instead of being multi-hit, it is a single hit that can cause high damage and knockback if timed correctly. His down special is Luigi Cyclone, a variation of Mario Tornado with only two hits and different knockback.

Boss

 * MetalMarioIcon(SSB).pngMetal Mario: A spin-off from a form Mario can take in Super Mario 64, Metal Mario makes his gaming debut as an unplayable minor boss in the 1P Game mode. He is fought in Stage 9, on his own stage, Meta Crystal. His moveset is identical to Mario's, with minor differences. Metal Mario barely flinches to ordinary attacks and is almost unaffected by throws at low percentages. In addition, he has extremely fast falling speed due to his weight. Although he is mute in this game, whenever he moves, he makes metallic sounds.

Stages

 * PeachsCastleIconSSB.pngPeach's Castle (Starter): This stage takes place in the sky above Peach's Castle from Super Mario 64. The actual castle itself can be fully seen in the background. There are two main platforms, the top which is a long bridge that players can go through. The bottom platform has a larger block moving left and right underneath it. On the top two corners there are two floating, inward-angled platforms that move slowly up and down. There is also a floating Bumper on the top center of the stage that slowly moves left to right.
 * MushroomKingdomIconSSB.png  (Unlockable): The game's only unlockable stage, Mushroom Kingdom is an audiovisual throwback to the original Super Mario Bros. In the middle of the stage is a long pit. Above the pit are two platforms that move up or down depending on the weight on them. On either side of the pit are suspended platforms and Warp Pipes that players can go through. Piranha Plants will occasionally come out of the pipes and can damage players. A Pow Block will randomly spawn in the air that players can interact with.

Items

 * Fire Flower: This power-up is a semi-sentient orange flower imbued with the power of fire. In many Mario platformers, Mario and Luigi can pick this up and gain the ability to launch fireballs from their hands. In Smash 64, however, it is used more as a weapon that can be wielded to project a continuous stream of fire into the area in front of the wielder.
 * : This power-up is found in many Mario platformers. It is a glowing yellow star with eyes that bounces around after being spawned. If Mario touches it, he will be made invincible for a short period of time, during which any enemy that touches him will be instantly defeated. In Smash 64, touching a Starman will make the player invincible for a total of 10 seconds.
 * Green Shell: Koopa Troopas come in different colors of shells. A green-shelled Koopa is the most common Koopa found in several Mario games. It walks off the edges of platforms, and if jumped on by Mario, it recedes into its shell. The shell can either be kicked or thrown at enemies. In Smash 64, a Green Shell can be thrown at players to cause them damage.
 * Red Shell: A red-shelled Koopa is found in many Mario games. Unlike a green-shelled Koopa, a red-shelled Koopa does not walk off edges, but it can recede in its shell after being jumped on and the shell can be kicked in the same way. In Smash 64, after a Red Shell is thrown, it will actively target the nearest player on the ground, damaging them in the process.
 * Bob-omb: This common enemy is a walking black bomb that patrols around and explodes in many Mario games. In some games, a Bob-omb can be picked up and thrown at an opponent as a volatile projectile. In Smash 64, a Bob-omb can be picked up and thrown at to cause a big explosion. If not picked up, it will start to walk on its own until it self-destructs.

Music

 * : A remix of the original stages music from the original Super Mario Bros.. It is in fact, a mixture of the world ground and underground themes. It is heard on the stage Peach's Castle.
 * : The original chiptune theme from the first stage of the original Super Mario Bros.. It is heard on the stage Mushroom Kingdom under normal circumstances.
 * : The original chiptune "Hurry Up" version of the normal stage music heard in the original Super Mario Bros.. It is heard on the stage Mushroom Kingdom when there are 30 seconds left and during Sudden Death.
 * 15: Mario Wins: The victory theme of both Mario and Luigi is an orchestration of the standard "Stage Complete" theme heard on the original Super Mario Bros..
 * : A remix of the "invincible" music that would occur when Mario picks up a Starman in Super Mario Bros., and it occurs when the player picks up the Starman item during a match.

In Super Smash Bros. Melee
Melee has a lot more Mario content than before. Three new characters join Mario and Luigi as playable characters, and the Mario universe continues to have the most stages and items, along with having the most trophies. Three bosses also appear, one being considered half Mario, half Smash Bros. property. Sub-universe characters and  return as well.

Fighters

 * MarioIcon(SSBM).png (Starter): Mario returns as a starter character, now having his appearance being based on Nintendo 64-era artwork, such as Super Mario 64 and Mario Kart 64. When making the transition from Smash 64 to Melee, Mario was neither strongly buffed nor strongly nerfed. This again makes him a balanced fighter without any glaring advantages or disadvantages. He can now wall jump just like in his games, and is now given a side special, which is the Cape from Super Mario World. The Cape reflects projectiles and spins characters in the opposite direction.
 * LuigiIcon(SSBM).png (Unlockable): Luigi returns as an unlockable character, whose appearance is once again based on his design in Nintendo 64-era artwork, such as Mario Kart 64. Luigi is no longer a full on clone of Mario, but is considered a semi-clone. This is because he gained a few new neutral attacks. Luigi also gained a side special, which is Green Missile. This move can be charged, and once let go, Luigi is launched sideways like a rocket, causing damage. Luigi is notable for having the longest wavedash in the game. Overall, Luigi got a slight buff compared to his previous appearance.
 * PeachIcon(SSBM).png (Starter): Peach is the princess of the Mushroom Kingdom who usually gets kidnapped and must be rescued by Mario. She first appeared in Super Mario Bros., where she needed to be rescued from the evil Bowser. In Melee, Peach is a new starter character, with her appearance being based around Nintendo 64-era artwork, such as Super Mario 64 and Mario Party 3. She is a lightweight character with the unique ability to hover in the air when holding the jump button. Her neutral special is, a counterattack where she pulls out Toad to reflect damage. Her side special is Peach Bomber, a horizontal attack where Peach attacks with her hip. Her up special is Peach Parasol, where Peach pulls out her parasol to slowly float down. Peach's down special is Vegetable which is based on a way to attack in Super Mario Bros. 2. Peach would pull out a turnip (occasionally an item) from the ground, and throw it at opponents.
 * BowserIcon(SSBM).png (Starter): Bowser is the main antagonist of the Mario franchise who first appeared in Super Mario Bros. Bowser constantly tries to kidnap Princess Peach and take over the Mushroom Kingdom with his army of Koopa Troopas, Goombas, and others. In Melee, Bowser is a new starter character, whose appearance is based on Super Mario 64 and Mario Kart 64. Bowser wields great power and bulk, but is lacking in agility due to his heavy weight. His neutral special is Fire Breath, an attack taken directly from Super Mario 64 where Bowser breathes fire in front of him. His side special is Koopa Klaw, where Bowser slashes and bites his opponent. His up special is Whirling Fortress, which is loosely based on the Koopalings going in their shells and spinning sideways. Bowser's down special, Bowser Bomb, comes from Super Mario Bros. 3 where Bowser would jump up and perform a ground pound.
 * DrMarioIcon(SSBM).png (Unlockable): Dr. Mario is simply Mario in a doctor's uniform from the puzzle spin-off series, Dr. Mario. In it, Mario dresses up as a doctor and throws Megavitamins into a bottle to destroy three species of Viruses trapped within. In Melee, Dr. Mario appears as a new unlockable character. He is a clone of Mario with some slightly altered specifications. In general, Dr. Mario's attacks are stronger than Mario's, but with slightly shorter reach and recovery. He has a different neutral special, Megavitamins. These are pill projectiles that act similar to Fireballs, except they do a little more damage and have a slightly longer range. His side special is Super Sheet, which is slightly slower, longer and more powerful than Mario's Cape. His up special is Super Jump Punch, just like Mario but a bit stronger. His down special is Dr. Tornado, similar to Mario's down special but it is a little stronger and deals less hits.

Bosses

 * MetalMarioIcon(SSBM).pngMetal Mario: Metal Mario returns in Melee to play the same role of minor boss again. Metal Mario is encountered in the eleventh stage of the Adventure Mode. Here, Metal Mario must be fought on the stage, after the player defeats the fifteen Fighting Wire Frames. Just like before, Metal Mario is a heavy, flinch resisting clone of Mario. The only difference from Smash 64 is that he does not resist as much knockback. One should note that the player can play as and fight against a Mario under the effect of the Metal Box.
 * MetalLuigiIcon(SSBM).pngMetal Luigi: Metal Luigi makes his first, and only appearance as a single character in Melee. Here, he plays the role of minor boss along with Metal Mario in the eleventh stage of the Adventure Mode. The player can only fight against Metal Luigi if Luigi has already been unlocked. Naturally, Metal Luigi is a heavy, flinch resisting clone of Luigi. Just like Metal Mario, Metal Luigi is mute and only makes metallic noises when moving. One should note that the player can play as and fight against a Luigi under the effect of the Metal Box.
 * GigaBowserIcon(SSBM).pngGiga Bowser: Giga Bowser is the gargantuan and powered up version of Bowser. He makes his gaming debut in Melee. Because he only appears in Smash Bros., and his trophy is under the  universe, he is considered half Mario, half Smash Bros. property. In Melee, he is the secret final boss of both the Adventure Mode, and the Event Mode. He is fought on the stage Final Destination in both instances. Although he is more than twice the size of Bowser, his moveset is almost identical to Bowser's. His attacks are considerably stronger in power, knockback, and range.

Stages

 * PrincessPeachsCastleIconSSBM.png Mushroom Kingdom: Princess Peach's Castle (Starter): Taking place on the rooftops of Peach's castle, this stage is far more representative of the castle in its Super Mario 64-onward incarnation. Occasionally, one of three colored buttons spawn on the stage, and when pressed on, some "!" blocks and two semi-solid platforms of the same color will spawn. Sometimes, a Banzai Bill will appear from a random side of the screen (including the top) and move in a slow straight path until it crashes into the castle, creating an explosion.
 * RainbowCruiseIconSSBM.png Mushroom Kingdom: Rainbow Cruise (Starter): In homage to the final stage of Super Mario 64, this stage is an aerial obstacle course that has a scrolling camera. It starts off on a flying ship (with two semi-solid platforms) that is facing left. After some time, the ship sinks, and players must travel through many moving and collapsing platforms. This is when the players must keep up with the scrolling camera. The stage moves in a clockwise order and at the end, it returns to where it started, getting ready for another cycle to start.
 * MushroomKingdomIconSSBM.png  (Starter): The spiritual successor to the Mushroom Kingdom stage of the original Smash Bros., this Mushroom Kingdom stage is once again a homage to the original Super Mario Bros.. The stage is split up into three sections: two walk-off small sections on the left and right, and one main section in the middle. Between the outer ones are two pits. Above the ground, the are rows of Brick Blocks than can be broken. Sometimes, "?" blocks may appear instead. Hitting one of these blocks will make an item spawn.
 * MushroomKingdomIIIconSSBM.png Mushroom Kingdom II (Unlockable): This stage functions as a throwback to Super Mario Bros. 2. Like Mushroom Kingdom, this stage consists of three sections, the left and right which are walk-offs. The middle section is a little lowered, and between the sections are pits. The waterfall in the background can produce small logs which players can stand on until they fall into the pits. Randomly, Birdo appears as a stage obstacle shooting out eggs from her mouth. Pidgets can also appear riding on carpets that players can stand on.

Items
Bold italics denote an item new to the Smash Bros. series.
 * Fire Flower: Returns from Smash 64 with a different design.
 * : Returns from Smash 64 essentially unaltered in function and purpose.
 * Green Shell: Returns from Smash 64, essentially unaltered in function and purpose.
 * Red Shell: Returns from Smash 64 essentially unaltered in function and purpose.
 * Bob-omb: Returns from Smash 64, essentially unaltered in function and purpose.
 * Freezie: Freezies are enemies from the original Mario Bros. that kill Mario and Luigi upon a contact. In Melee, when it appears, it slides in one direction and will fall off the stage if not picked up in time. It can be hurled at opponents to encase them in a slab of ice, and they will be temporarily frozen as others attack him or her and pile on the damage without any knockback.
 * Super Mushroom: An iconic power-up from the original Super Mario Bros. that carried on to almost every other Mario game. In many of its appearances, the Super Mushroom increases whoever grabs it in size and extends their life meter by one. In Melee, if a player touches one, they grow in size and increase their bulkiness and strength for a short period of time.
 * Poison Mushroom: An item from Super Mario Bros.: The Lost Levels. Poison Mushrooms looked similar to Super Mushrooms, but would actually hurt Mario, instead of making him bigger. In Melee, the Poison Mushroom is an item that looks like the Super Mushroom but will cause the character it touches to temporarily become tiny, and therefore much weaker and lighter.
 * Metal Box: An item based on the Metal Box from Super Mario 64. This would provide Mario with a Metal Cap, allowing him to change into Metal Mario, giving him much greater weight and power. In Melee, albeit without the cap; characters temporarily into a living metal model of themselves, increasing their resiliency but also their dropping weight, and making them mute.

Enemies

 * Goombas: First appearing in Super Mario Bros., these brown creatures are described as traitors to the Mushroom Kingdom that operate under the employ of Bowser. They walk sideways and damage whoever they bump into, but are easily defeated by bouncing off their heads. They act the same way in Melee where they appear on the first stage of Adventure Mode.
 * Green Koopa Troopas: First appearing in Super Mario Bros., these turtle-like henchmen of Bowser's army who walk off ledges and retract into their shells when jumped upon, and the shell can be picked up and thrown or kicked at other enemies in many Mario games. This is fully reflected in their appearances in Melee, where they appear on the first stage of Adventure Mode.
 * Red Koopa Troopas: First appearing in Super Mario Bros., these red shelled versions Koopa Troopas do not walk off ledges, but they still retract into their shells when jumped upon, and their shells can still be used at items to throw and kick at other enemies. This is fully reflected in their appearances in Melee, where they appear on the first stage of the Adventure Mode.
 * Green Koopa Paratroopas: First appearing in Super Mario Bros., these are Green Koopas Troopas that have white wings on their shell. They fly in set patterns, and when Mario jumps on them, they lose their wings and convert into regular Green Koopa Troopas. This is fully reflected in their appearances in Melee, where they appear on the first stage of Adventure Mode.
 * Red Koopa Paratroopas: First appearing in Super Mario Bros., these are Red Koopas Troopas that have white wings on their shell. They fly in set patterns, and when Mario jumps on them, they lose their wings and convert into regular Red Koopa Troopas. This is fully reflected in their appearances in Melee, where they appear on the first stage of Adventure Mode.

Music

 * : An orchestrated remix of the famous stage music from the original Super Mario Bros, with elements of the same game's "underground" theme overlapping with it. It is heard on the Princess Peach's Castle stage in Vs. Mode, and also as the primary music for Mushroom Kingdom Adventure. It is also used as Bowser's credits theme. It is Song 1 in the Sound Test.
 * : A medley of two Mario series tracks. The first half of the track is the remixed first half of an energized tune heard in Super Mario 64, while the second half is a remix of the underwater theme heard in Super Mario Bros. It is also used as Peach's credits theme. It is Song 2 in the Sound Test.
 * : A perfect preservation of the original chiptune normal stage music heard in the original Super Mario Bros., appearing on Mushroom Kingdom as the primary track. It is Song 21 in the Sound Test.
 * : The original chiptune "Hurry Up" music heard in Super Mario Bros. It is heard on the stage Mushroom Kingdom when the match's timer reached thirty seconds. It is Song 22 in the Sound Test.
 * : The original chiptune normal stage music heard in Super Mario Bros. 2, appearing on Mushroom Kingdom II as the primary track and as Luigi's credits theme. It is Song 23 in the Sound Test.
 * : The original chiptune Boss music in Super Mario Bros. 2, appearing on Mushroom Kingdom II as the primary track when the match's timer reached thirty seconds. It is Song 24 in the Sound Test.
 * ''': A synthesized rock-based medley of the first stage music and the first overworld music in '. It is heard as a secondary track on Yoshi's Island and the single-player Mushroom Kingdom Adventure. It is also used as Mario's credits theme. It is Song 30 in the Sound Test.
 * ': A synthesized remix of the Fever'' music track first heard in the original ' and all of its sequels. This is heard as a secondary track on both Mushroom Kingdom and Mushroom Kingdom II. It is also used as Dr. Mario's credits theme. It is Song 36 in the Sound Test.
 * Mario's Victory: The victory theme of Mario, Luigi, Peach, Bowser, and Dr. Mario is an orchestration of the standard "Stage Complete" theme heard in Super Mario Bros.. It is Song 38 in the Sound Test.
 * : A remix of the "invincible" music that would occur when Mario picks up a Starman in Super Mario Bros., and it occurs when the player picks up the Starman item in a match. It is Song 77 in the Sound Test.

In Super Smash Bros. Brawl
In a maneuver both traditional and expected, Super Smash Bros. Brawl is rife with Mario-based content. In addition to every previous character from the universe (sans Dr. Mario, making Brawl the only Smash Bros. game to cut a Mario character) returning, the sub-franchise revolving around series anti-hero Wario has been recognized as its own universe for this game, as well as Diddy Kong joining Donkey Kong as the second Donkey Kong fighter. Yoshi returns as well. Discounting the sub-universes, Mario is third only to Pokémon and in terms of total characters (counting the  as three separate characters and Zelda/Sheik as two) and has twice as many stages as the next most represented franchise. Brawl is also the last game in the series to have an unlockable Mario stage.

Fighters
Four characters from the Mario franchise are playable in Brawl, not counting any sub-franchises, in which case the total number is eight. On the final character select screen (after all characters are unlocked), the first two columns are dedicated to the playable Mario characters, with the first column being the Mushroom Kingdom denizens, and the second column being the sub-series stars.
 * MarioIcon(SSBB).png (Starter): Mario, the face of gaming, was given a slight character model redesign for his appearance in Brawl as his appearance is based on his current design from the later Mario games, such as Luigi's Mansion, Super Mario Sunshine and Mario Party 4. He is also armed with F.L.U.D.D. this time around, replacing the Mario Tornado from the previous games. Like the rest of the Brawl roster, Mario has a new Final Smash. His is a massive fireball that expands as it engulfs the stage, called the Mario Finale. Mario is ranked 31st in the current tier list, his balance an impediment when others excel in many areas.
 * LuigiIcon(SSBB).png (Unlockable): Luigi returns as an unlockable veteran once again. He remains similar to his brother, but has been further differentiated from him with several new attacks. In addition, Luigi still retains his Luigi Cyclone, giving him another special move unique from Mario. Like Mario, his appearance is also based on his current design from the later Mario games, such as Luigi's Mansion and Mario Party 4. Luigi's Final Smash, Negative Zone, creates a huge circular field of energy that has random effects on enemies caught inside. He is currently 28th on the tier list, his bizarre physics both a boon and a curse.
 * PeachIcon(SSBB).png (Starter): Peach reappears from Melee. Her model has been updated to match her current design introduced in Super Mario Sunshine. Her new Final Smash, Peach Blossom, involves Peach blowing numerous kisses that damage all enemies and put them to sleep while a vast amount of peaches fall from the sky. Though she has fallen from her high Melee showing to 19th on the tier list, she is still a solid choice and is still the highest ranking of the non-subseries Mario characters.
 * BowserIcon(SSBB).png (Starter): Bowser also makes a return after first appearing in Melee. His appearance is based on his current design from the later Mario games, such as Luigi's Mansion, Super Mario Sunshine and Mario Party 4. His newfound Final Smash is Giga Bowser Transformation, in which he transforms himself to Giga Bowser for 10 seconds to increase his power substantially. Bowser is considered the least viable of the Mario universe characters, even when subseries are taken into account, clocking in at 33rd on the tier list. Giga Bowser (in both Brawl and Smash 4) is part of Bowser's Final Smash. So since he appears as a semi playable character and as a Final Smash trophy for Brawl and Super Smash Bros. for Wii U, he leaves the boss roster until his appearance in Super Smash Bros. Ultimate.

Boss

 * Petey.jpgPetey Piranha: A recurring character in contemporary Mario games, Petey appears in the Subspace Emissary mode as the first Boss fought. He captures Peach and Zelda in cages, and uses them to attack the player. The player's goal is to free one of the princesses by attacking their cage. When Petey is defeated, the most damaged cage is broken, and the princess inside is saved. The unsaved one is then turned into a trophy by Wario.

Stages
In total, when sub-franchises are accounted for, 12 of the 41 playable non-custom stages are based off the various Mario-related games. Only the six stages with the Super Mushroom icon are listed below. For the Yoshi stages, see Yoshi's Island (SSBB) and Yoshi's Island (SSBM) (for info on the Melee stage). For the Donkey Kong stages, see 75m, Rumble Falls, and the Melee stage Jungle Japes. For the Wario stage, see WarioWare, Inc. (the only Wario stage in the whole game).
 * Icon-rainbowcruisemelee.gifMelee Stages: Rainbow Cruise (Starter): A returning stage from Melee. It is basically unaltered.
 * Icon-delfinoplaza.gifDelfino Plaza (Starter): Based on the main hub area from . Taking place at first on a platform, the stage flies around and through the plaza area and touches down at certain parts, where the current area in the plaza itself then becomes the ground for the stage for a period of time, and then the platform swoops in and carries the player to another area. The stage's movement mechanics are similar to Melee’s.
 * Icon-mushroomykingdom.gifMushroomy Kingdom (Starter): While the two previous Smash Bros. games have featured Mushroom Kingdom stages based on the original Super Mario Bros., Mushroomy Kingdom is a full recreation of from Super Mario Bros., apparently aged since the original Super Mario Bros. from a vibrant green land into a barren desert. However, while the previous Mushroom Kingdom stages were in a pixel-art style, the Mushroomy Kingdom stage is a completely enhanced version of the stage, even featuring a fitting mix of the original Overworld theme. From time to time,, an underground level, will load, instead of World 1-1.
 * Icon-mariocircuit.gif (Starter): This stage is taken from the ' series, and takes place at an intersection of a figure-8 track that's a bit like from ', with Shy Guys racing through it on karts. Players can be damaged if they make contact with any passing Shy Guys.
 * Icon-luigismansion.gifLuigi's Mansion (Unlockable): Luigi's Mansion is based on the game of the same name. There are pillars in the mansion that can be destroyed to make the whole mansion fall apart. The Mansion eventually comes back together again.
 * Icon-mariobros.gifMario Bros. (Unlockable): A recreation of the classic  game, complete with enemies. A stage that almost completely throws the rules of Smash Bros. out the window, KOing opponents normally here is notoriously difficult due to the way the stage is arranged. Instead, the enemies are a player's main means of scoring KOs by using them as projectile weapons.

Items
Bold italics denote an item new to the Smash Bros. series. All items except for the Red Shell return. All these items are classified within the main Mario series. For information on the Hammer and Spring items, see the Donkey Kong universe page.
 * Fire Flower: The Fire Flower returns from the previous Smash Bros. games, redesigned to match its appearance in recent Mario titles. It remains functionally identical to previous Smash titles. However, thanks to the new physics of Brawl, it can now be used while moving around and jumping.
 * : Returns from Smash 64 and Melee, now using the jingle from the original Super Mario Bros.
 * Green Shell: The Green Shell returns from Smash 64 and Melee, essentially unchanged.
 * Bob-omb: The Bob-omb returns from Smash 64 and Melee, essentially unaltered as a very potent throwing weapon.
 * Freezie: The Freezie returns from Melee without significant changes.
 * Super Mushroom: Returns from Melee without significant changes, and returns as a mode in Special Brawl.
 * Poison Mushroom: The Poison Mushroom returns from Melee without significant changes, and also returns as a mode in Special Brawl.
 * Metal Box: The Metal Box returns from Melee with the same basic function and purpose. It is also a mode on Special Brawl.
 * Golden Hammer: The Golden Hammer is an item in Brawl, originating from the game Wrecking Crew. It acts similarly to a regular Hammer, but it improved in every way. It is more powerful, is swung faster, and can even let the user float in midair. However, it is exceptionally rare. Also, like the Hammer's Headless Hammer, the Golden Hammer can become the Golden Squeaky Hammer, which is useless and a liability the character is trapped into "using" until it disappears (but at least its hammer head does not fall off so that opponents can pick it up and throw it at the player).
 * Hothead: A new item hailing from Super Mario World. This fiery sun-like entity travels across and around platforms and walls, damaging what it collides with, both in its original game and in Brawl when picked up and thrown by a character. The Hothead does not harm the character that activates it.
 * Banana Peel: A staple "weapon" from the Mario Kart series which racers typically drop behind them so that racers behind run over them and spin out and get slowed down. In Brawl when it is thrown on the ground by a character, his opponents will slip on it and fall down if they step on it, getting slightly damaged and being temporarily incapacitated.
 * Lightning Bolt: Hailing from the Mario Kart series, it does exactly what it does in the series, shrinking all characters on the stage except for the one who used it. However, it occasionally backfires, and shrinks the player who activated it. It also may shrink every player.
 * Soccer Ball: A soccer ball that when hit, will go flying covered in flames, dealing major damage to opponents hit by it. This behavior originates from Super Mario Strikers.
 * : Although debuting in Brawl, it can't be considered a part of the Super Smash Bros. universe as it only comes after Peach's Final Smash, Peach Blossom. It heals 5% damage if eaten.

Assist Trophies
The Mario franchise features easily the most commonly summoned Assist Trophy characters with a total of three (whereas no other represented franchise has more than one) - this total goes up to four when Kat & Ana (from the Wario series) is counted.


 * Hammer Bro: A single member of the duo that Mario has fought since Super Mario Bros., Hammer Bro somewhat predictably tosses hammers at the foe when summoned, and then disappears.
 * Lakitu and Spinies: Appearing in his original 8-bit form from Super Mario Bros., Lakitu throws Spinies at the ground, which wander around damaging players like they did in the original game. That being said, Lakitu can receive damage from opponents and be defeated prematurely.
 * Waluigi: Luigi's mischievous and villainous answer to Wario, known almost exclusively through his Mario spin-off appearances. Waluigi runs to an opponent, stomps them into the ground, and then either finishes them off with a solid kick or a smack with his tennis racket.

Common Enemies

 * Goomba: Appear as common enemies in the Subspace Emissary. They can be seen helping several of 's minions in stealing & 's banana hoard to lure the two Kongs into Bowser's clutches. They appear in later stages as well, such as The Great Maze, as common enemies.
 * Koopa Troopa: Appear as common enemies in the Subspace Emissary. They also help steal Donkey Kong's and Diddy Kong's banana hoard.
 * Koopa Paratroopa: Appear as common enemies in the Subspace Emissary. They also help steal Donkey Kong's and Diddy Kong's banana hoard. They float in midair, as well as hop to and fro. They are typically defeated in one or two hits.
 * Giant Goomba: Appear as common enemies in the Subspace Emissary, and behave in the same manner as standard Goombas, but are larger and more powerful.
 * Hammer Bro.: Appear as a common enemies in the Subspace Emissary mode. They also appear as Assist Trophies. They throw several hammers at foes, however, because they do not aim at enemies directly, the hammers are fairly easy to dodge, and do little damage.
 * Bullet Bill: Appear as common enemies in the Subspace Emissary, and behave similarly to how they acted in Mario platformers, shooting across the screen to hit the player character.

Music
By far, the Mario series has the most music tracks in the game (not counting tracks based on musical motifs that originated in the Smash Bros. series). Only tracks from the main Mario series are listed here (even then, not all are classified in-game under the Super Mario Bros. series).

In Super Smash Bros. 4
As with past installments, the Mario franchise is well represented in Super Smash Bros. 4. The four primary fighters from Melee and Brawl — Mario, Luigi, Peach and Bowser — were confirmed to return in no more than three months after the games' official showcase at E3 2013. After a hiatus of new representation in Brawl, the series received newcomers in Rosalina & Luma and Bowser Jr., as well as the return of Melee fighter Dr. Mario. Even with the conclusion of DLC in February 2016, the Mario franchise still has the most playable fighters, excluding the series-related characters Donkey Kong, Diddy Kong, Yoshi, and Wario, who all return as well.

Fighters

 * MarioIcon(SSB4-U).png (Starter): Mario was revealed alongside the games at June 11, 2013, expectedly. While accented, his design is less detailed than in Brawl and closely reflects his more recent appearances in the Super Mario series. Mario himself has received significant buffs in the transition from Brawl and his frequent usage in competitive play reflects this.
 * LuigiIcon(SSB4-U).png (Starter): Luigi was revealed during the Nintendo Direct of August 2013, as part of Nintendo's "Year of Luigi" commemoration. Like his brother, his design is less detailed and reflects the more recent Mario games. Luigi's jump is now his trademark that debuted in ', and his Final Smash is now the Poltergust 5000 from '. Unlike the last three Super Smash Bros. games, where he had to be unlocked, Luigi appears as a starter character in both versions of the game.
 * PeachIcon(SSB4-U).png' (Starter): The confirmation of Peach's return was announced on the official website in September 2013, on the anniversary of ' original release. The detailing in her dress is brighter and has a more simplistic design, closer to her appearances in the Mario'' series. General aesthetics and moveset changes were made that reflect Peach's character, such as the inclusion of a pink ribbon in her up smash and a small rainbow in her up aerial.
 * BowserIcon(SSB4-U).png (Starter): Bowser, confirmed alongside Mario at E3 2013, has arguably received the greatest amount of changes out of all the returning Mario veterans. His dinosaurian, hunched posture from previous games is replaced with an upright stance. In correspondence with these changes, Bowser now uses his legs in many of his attacks as well as when dashing, as opposed to the scuttling animation from previous titles. Bowser's greater mobility and improved approach options have significantly benefited his utility in competitive play.
 * DrMarioIcon(SSB4-U).png (Unlockable): Originally, Dr. Mario was to be an alternate costume for Mario, but it was decided during development that the fans of his original moveset would appreciate the full character's inclusion. As a result, Dr. Mario returns from Super Smash Bros. Melee. He is the first fighter to be absent in between Smash Bros. installments, followed by the DLC fighters and . While his moveset was recreated faithfully, the changes made to Mario in Brawl make Dr. Mario more distinct from the fighter he was cloned from, and various tweaks done through the equipment mechanic also result in him functioning like a stronger, yet slower Mario. His Final Smash is a variation of the Mario Finale that uses giant Megavitamins, appropriately dubbed Doctor Finale.
 * RosalinaIcon(SSB4-U).png (Starter): The mysterious Rosalina debuted in 2007 as an important side character in '. She allied with Mario to defeat Bowser, who stole the stars she had used to power her . She is a celestial caretaker of the cosmos, who watches over the stars with her many star-shaped companions, the Lumas. Since her debut, Rosalina has received widespread acclaim and has had many reoccurring appearances in the platforming Super Mario games and the Mario Kart series. Rosalina - accompanied with Luma' — was announced for SSB4, the first newcomer unveiled after the E3 2013 showcase. Her character embodies a "puppet" mechanic, where one who controls Rosalina also controls Luma. Her unique physics and attributes are closely inspired by Super Mario Galaxy''. She is a starter character in both versions of the game, which is unique considering that Rosalina has had to be unlocked in every previous game she was playable in.
 * BowserJrIcon(SSB4-U).png (3DS: Unlockable; Wii U: Starter): Bowser Jr. is Bowser's spoiled son, introduced in the 2002 title '. Like his father, Bowser Jr. has the unquenchable desire to defeat Mario. He has become a reoccurring antagonist in the Mario series. This is especially prevalent in the New Super Mario Bros. subseries, where he often appears as the primary villain while Bowser takes a secondary role. In the subseries he pilots his, a flying, emotive vehicle that is stuffed with unorthodox weaponry. It is this interpretation of Bowser Jr. that appears in SSB4, where he pilots his Clown Car during battle and utilizes its bizarre gizmos. Uniquely, the Clown Car receives less damage when hit than Bowser Jr. himself, allowing for unique styles of defensive play. What's also special about Bowser Jr. is that he is not alone — instead of alternate colors, Bowser Jr. can be swapped with one of the seven Koopalings', who also use their own personal versions of the Junior Clown Car. Bowser Jr. and the Koopalings were leaked as playable characters during the ESRB leaks and were officially confirmed during The 50-Fact Extravaganza. He is an unlockable fighter in Smash for Nintendo 3DS, but is a starter character in Super Smash Bros. for Wii U''.

Each one has its own hazards, platform layouts, set order, and is based on a unique location. The three phases are:
 * Hither Thither Hill: a grassy plain from . A large windwill provides secondary rotating platforms. Towards the end of this phase, a large Fan Thing is erected on the left side of the stage and blows powerful gusts of wind. Paper Mario’s columnar Ω form is staged in this phase.
 * S.S. Flavion: a seafaring vessel from '. Due to the limitations of the 3DS system, the paper-made sea is not swimmable. The ship is occasionally approached by the giant from The Thousand-Year Door or is blasted into the sky by the  from the original '.
 * Bowser's Sky Castle: Bowser's flying fortress from Sticker Star. The main platform is a precarious, tilting bust of Bowser with two small rising platforms to its left and right.

for Wii U
Stages exclusive to the Wii U version. Unused data left in the game's files suggests that a stage based on  was planned but ultimately scrapped. Like Wily Castle and Gaur Plain, it would have included the es as bosses.
 * DelfinoPlazaIconSSB4-U.pngDelfino Plaza (Starter): staged on floating platforms that travels to various locations on the titular island plaza from . Like Skyloft, the primary platform brings the fight to various areas around town, such as the .

It is one of the possible stages to appear in Level 6 of All-Star Mode as a home stage for Peach and Bowser. Its Ω form is an unused section of track risen high above the raceway.
 * LuigisMansionIconSSB4-U.pngLuigi's Mansion (Starter): staged in the titular haunted estate from . The arena consists of the mansions interior and exterior.

Items
Bold italics denotes an item or Assist Trophy new to the Smash Bros. series.
 * Fire Flower (shooting): a fiery plant from Super Mario Bros. Wielding it allows the fighter to erupt flames from its floral disk, although prolonged usage of the flower causes the flames to get smaller and eventually die. When it spawns, the Fire Flower slowly falls to the ground and sways back-and-forth, like in the New Super Mario Bros. games.
 * Super Star (status): a bouncing, traveling star from Super Mario Bros. that grants temporary invincibility on contact.
 * Green Shell (throwing): the discarded shell of a Koopa Troopa from Super Mario Bros. that trails along the ground when tossed. Unlike in Brawl, its proportions more accurately reflect the modern design of the Koopas' shells. Red Shells appear in Smash Run with an identical function.
 * Bob-omb (throwing): a sentient bomb from Super Mario Bros. 2. When it spawns, it will sit idle unless picked up. If left waiting too long, its key will begin to turn and the bomb will begin to walk until it detonates.
 * Freezie (throwing): a sentient crystal of ice from  that freezes any opponents it is tossed at. Unlike in Brawl, it does not slide off of ledges, and it will freeze any fighters who actively attack it instead of picking it up.
 * Super Mushroom (status): a traveling red mushroom from  that causes the users to grow on contact. This increases the damage output, range, and knockback of their attacks at the expense of a bigger hurtbox.
 * Poison Mushroom (status): a traveling red mushroom from ' that causes the users to shrink on contact. Unlike the other returning items in the game, the Poison Mushroom's design has not changed to reflect its recent pink-spotted purple appearance in '.
 * Metal Box (status): a special type of block from  that turns the user into their metal form. In this state the user does not flinch very easily and is very strong, at the cost of being incredibly heavy.
 * Golden Hammer (battering): a rare hammer from . Like the regular Hammer, the Golden Hammer sets the user in a locked state of constantly whacking the hammer. The duration of the attack is much shorter than it was in Brawl. While normally very powerful, there is chance of the hammer being a harmless, squeezable toy that leaves the fighter wielding it vulnerable. Despite formal acknowledgement of a Wrecking Crew series, the Golden Hammer is still classified as a Mario item.
 * Hothead (throwing): a sentient ball of flames from  that travels along the platform it was thrown to. It does not damage the user and grows bigger and faster if it makes contact with fire or electric attacks.
 * Banana Peel (throwing): discarded fruit skin from Super Mario Kart. Tossing it at an opponent causes them to trip. With the removal of random tripping, it is one of the few instances in the game where fighters can legitimately slip. It alternatively could be tossed on the ground as a potential trip-causing trap. It is also part of 's moveset.
 * Lightning (status): a bolt of electricity from . Touching the item either shrinks all of the user's opponents, the user themselves, or everyone.
 * Soccer Ball (special): a seemingly generic ball that cannot be grabbed, but when hit, will fly across the stage as a dangerous, inflamed projectile. This attribute comes from the  games.
 * POW Block (throwing): a destructive block from Mario Bros. that launches grounded opponents into the air when hit or thrown, much like the POW Blocks in the and Mario Bros. stages. It shrinks after each consecutive hit and can be hit a total of three times before disappearing.
 * Fire Bar (battering): a new battering weapon based on the spinning bars of flame from Super Mario Bros. Every second time it makes contact with an opponent, it loses a fireball. The greatest knockback and damage output is at the base of the bar.
 *  (transformation): a sentient bullet item from . It spawns on stage as a small bullet that can be picked up. When "thrown", the user transforms into a large Bullet Bill and flies across the stage.
 *  (container): pluckable red stalks from . Upon pressing the attack button, the grass is plucked and with it comes a randomly selected item. If the item can be held, it automatically is in the character's hand. If the item is used by touching it, such as a Super Mushroom, it instantly takes effect.
 * Super Leaf (status): a tanooki leaf from . When equipped, the user sprouts raccoon ears and a ringed tail. It allows the user to float in mid-air like . During development, it potentially was also going to allow users to strike opponents with the tail, but this concept was scrapped. When fluttering, the floating sound effect from Super Mario 3D Land plays.
 * Spiny Shell (throwing): a spiny, blue Koopa shell from ' that homes in and strikes an opponent when tossed. Its design is based on its appearance in ' and .
 *  (throwing): a blue boomerang from  that can be tossed and return to the user after going a certain distance. When caught, its power increases. Boomerangs can be caught by opponents.

Assist Trophies

 * Hammer Bro.: an armored turtle from Super Mario Bros. that hops around and tosses hammers at opponents. It does not harm the summoner. Its design has been simplified to reflect its appearance in recent Mario titles. It also appears as an enemy in Smash Run.
 * Lakitu & Spinies: Lakitu is a cloud-riding turtle from Super Mario Bros. that flies to the top of the stage and drops Spinies onto opponents. It does not harm the summoner. Lakitu travels faster than it did in Brawl, making it more useful. They also appear as enemies in Smash Run.
 * Waluigi: Wario's mischievous partner from the Mario series. He dashes at a random opponent on stage and stomps them into the ground. After accumulating enough damage, he launches the opponent away with his tennis racket. He does not harm the summoner. He is the only Assist Trophy that does not also appear as an enemy in Smash Run. When Waluigi was unveiled during the "Smash Direct" of April 2014, he was presented as a Assist Trophy. This is notable because Waluigi had never appeared in a Wario title and Wario himself was not yet confirmed for SSB4.
 * Chain Chomp: a monster from  that resembles a toothy ball-and-chain. It lunges and chews on opponents within range of its chain, which is tied down by a post. Its post can be damaged by opponents and broken, releasing the Chomp onto the stage briefly before disappearing. It also appears as an enemy in Smash Run.

Smash Tour items

 * Super Mushroom ( Red ): a red mushroom from Super Mario Bros. The user starts battle in their giant form.
 * Poison Mushroom ( Red ): a red mushroom from Super Mario Bros.: The Lost Levels. The user shrinks a foe at the start of battle.

Enemies
Enemies that appear in both Smash Run in the 3DS version and Smash Tour in the Wii U version.
 * Kamek : Bowser's elderly attaché in the Mario and series.

In Super Smash Bros. Ultimate
The Mario universe once again has considerable representation in Ultimate. Despite already having the most characters in Smash 4, the Mario universe introduced two new fighters in the form of Daisy, an echo fighter of Peach, and Piranha Plant, the first DLC character for Ultimate. However, between returning characters and newcomers, the Pokémon universe now has more playable characters compared to Mario. All the characters from Mario's sub-universes also make a return, with the new addition of King K. Rool, included under the Donkey Kong universe. This is the first title since SSB where Mario is the only Mario universe fighter available from the start.

Fighters

 * 01. MarioIcon(SSBU).png (Starter): the title character of the Mario franchise: "Mr. Video Game himself". He was suggested to appear during Ultimates then unnamed teaser trailer at the end of the March 8th, 2018 Nintendo Direct, and was later formally announced along with all other veterans during E3 2018. His moveset has been retained, but the animations for many of his attacks have been exaggerated and reflect changes to their mechanics. His dash attack no longer allows him to slide under projectile attacks. His design is based on his appearance in Super Mario Odyssey''. Mario's traveling companion from ' - - has replaced his standard cap, but he only reveals himself occasionally when Mario uses Super Jump Punch and through Mario's new side taunt, during which he tosses Cappy around in a circle. Mario has two new costumes: one is his builder outfit from ' and the other is his wedding tuxedo from '. Mario is one of eight characters available from the start, but he must be unlocked in Adventure Mode: World of Light. In this mode, he must be defeated on Final Destination and is always the first character unlocked during the campaign.
 * 09. LuigiIcon(SSBU).png (Unlockable): Mario's lankier twin brother: "the eternal understudy". He was the second-to-last veteran announced to return during E3 2018. Luigi returns once again as an unlockable fighter after being a starter in Smash 4. While Luigi retains many of his moves, he is much less slippery than in previous Smash Bros. entries and now has a new running animation derived from '. As alluded to during 's reveal trailer "Vampire Killer", Luigi now uses the Poltergust G-00 from ' for all of his grabs and throws. To unlock him, he must be defeated on the Luigi's Mansion stage.
 * 13. PeachIcon(SSBU).png (Unlockable): The Princess of the Mushroom Kingdom also returns, this time as an unlockable fighter after being a starter in Melee, Brawl, and Smash 4. Her design has been slightly modified, her dress physics return from Melee, and her particle effects have been greatly enhanced. Toad is more present in Peach's moveset now, participating in more attacks. With an increase in mobility and a better combo game thanks to improved moves, Peach is considered to be one of the best characters in the game.
 * 14. BowserIcon(SSBU).png (Unlockable): The King of the Koopas returns as an unlockable fighter for the first time after being a starter in Melee, Brawl, and Smash 4. His design is more monotone and dark, and his hair now has some physics-based movement. Bowser has received changes to mobility and power, although his infamous kill confirm from Smash 4 was removed. Bowser also received an updated Final Smash called Giga Bowser Punch, which has him teleport to the background of the stage, aim a reticle, and punch opponents in his Giga Bowser form. Giga Bowser is no longer a full moveset transformation Final Smash, but does one move (as Final Smashes for Ultimate were standardized and straight to the point).
 * 18. DrMarioIcon(SSBU).png (Unlockable): Dr. Mario returns as an unlockable fighter, and while he is still a clone of Mario, he is not labeled as an Echo Fighter. His design has received some minor changes regarding coloration, and his damage output and mobility has received some buffs. Dr. Mario also received a new down air that meteor smashes, akin to Captain Falcon and Ganondorf's equivalent move.


 * 48. RosalinaIcon(SSBU).png (Unlockable): Rosalina and her loyal servants return as an unlockable fighter after being a starter in Smash 4. Her design has been tweaked to be more like her appearance in Mario games. Rosalina was nerfed during the transition, with most of her best moves from Smash 4 being nerfed. Luma has also been nerfed, being KO'd much easier than in SSB4 and having more end lag on some of his moves.


 * 58. BowserJrIcon(SSBU).png (Unlockable): The Prince of the Koopas returns as an unlockable fighter after being a starter in Super Smash Bros. for Wii U. Like his father, Jr.'s design is much simpler compared to his Smash 4 counterpart. Bowser Jr.'s moveset has been mostly retooled to be more effective and less situational, at the cost of nerfs to his best moves from Smash 4. Like in Smash 4, the Koopalings appear as alternate costumes.


 * 13ε. DaisyIcon(SSBU).png (Unlockable): The princess of Sarasaland and a recurring character in Mario spin-off games makes her debut as an unlockable Echo Fighter of Peach. Unlike previous clones, there are no noticeable gameplay differences between Peach and Daisy, though Daisy has altered idle and running animations, along with some aesthetic differences (such as several of her attacks using yellow flower petal effects instead of pink heart ones).


 * 70. PiranhaPlantIcon(SSBU).png (DLC): The infamous recurring plant from the Mushroom Kingdom makes its debut as Ultimate's first DLC fighter. Its moveset and alternate costumes all make references to its many incarnations throughout the Mario series, and some of its alternate costumes have it fight inside a Warp Pipe instead of its usual pot. For its Final Smash, Piranha Plant summons Petey Piranha, who attacks in a similar fashion to his Subspace Emissary incarnation.

Boss

 * Giga Bowser SSBU.pngGiga Bowser: Giga Bowser returns as a boss in both Classic Mode and World of Light. In Classic Mode, Giga Bowser appears as the boss for and ’s routes. Unlike in Melee, the player has to deplete Giga Bowser’s health bar to defeat him rather than knocking him off the stage.
