Mario's aerial attacks and Dr. Mario's identical, derived
animations in Super Smash Bros. Melee.

A clone (officially known as a "model swap character" (モデル替えキャラ) on Melee's Japanese website, and as an Echo Fighter in Super Smash Bros. Ultimate) is a character with a moveset that is considerably similar to another character's. Often, the clone's moveset will have a few tweaks made, and may have their physics altered to a degree, but on the whole, the characters are similar and typically have the same special move mechanics, to such a degree that both characters can be played optimally using a very similar or even identical playstyle. Clones are a common inclusion in various fighting games, as developing a character using an existing one's moveset and/or model as a base is less time- and resource-consuming than starting from scratch.

Semi-clone is a term used for characters who share some of their moveset with another character, with some similarity in physics, but have enough differentiating moves and characteristics that calling them a "clone" wouldn't be entirely accurate. "Semi-clone" status can differ among players' minds depending on their basis of the term; for example, one basis for dubbing a character a semi-clone would be their differences in special moves from the character they are cloned from. This process of a clone breaking away from its roots and establishing its own identity as it undergoes divergent evolution is known in the Smash Bros. community as Luigification, named after how Luigi originally was a clone of Mario but eventually came into his own in both the Super Mario and Smash Bros. series. Jigglypuff is the only character who started as a semi-clone and eventually became its own completely unique character.

Super Smash Bros. 4 introduces alternate characters that act as alternate costumes, namely Alph for Olimar and the Koopalings for Bowser Jr. They have their own voice clips and the Announcer refers to them by name. However, since they bear no gameplay differences and are not treated as separate characters, they are not considered to be clones.

The term "clone" is also used to refer to individual moves cloned from another character's move. For example, Falco's Blaster is a cloned move of Fox's Blaster, with the former being the same general type of attack with animations taken from the latter, but with altered properties and functioning so that makes it its own move. Usually cloned moves share animations, while altering the cloned move's function and/or properties in some way, though sometimes the inverse happens, such as in the case of Ness's and Lucas's down tilts in Brawl; Ness's down tilt is a low rapid kick where he pokes his foot out, while Lucas's involves him rapidly spinning around while kicking, but both have identical functioning as extremely fast but extremely weak low kicks that semi-spike with a high tripping chance. Cloned moves can also happen between characters who otherwise have no other aspects cloned, such as Charizard's Flamethrower being cloned from Bowser's Fire Breath, both being the same type of move with identical animations and functioning, but with a minute property difference (Charizard's Flamethrower reaches farther with thinner hitboxes in Super Smash Bros. Brawl, and in Smash 4 it flinches with all its hitboxes, while Bowser's Fire Breath does not do so, alongside his move covering a larger area).

Clones or semi-clones are almost always unlockable or downloadable characters rather than starter characters. The only exceptions are Lucas in Brawl, Luigi and Toon Link in SSB4, and Ganondorf exclusively in Super Smash Bros. for Wii U.

Clones in Super Smash Bros.

Smash 64 only had one clone in Luigi, and a semi-clone in Jigglypuff, with the rest of its cast consisting of unique characters. All of the unlockable characters were created with the premise of reusing some of the preexisting characters' movements and models.

Original	Clone	Differences
Mario	Luigi	Luigi's dash attack and down tilt are unique moves. All three of his special moves have slight differences: Luigi Cyclone launches foes instead of sucking them in, Luigi's Fireballs are immune to gravity, and the Super Jump Punch either does massive damage and knockback or almost none. His taunt is also different. Overall, Luigi has slightly lower frame data and power than Mario, but has better KO ability due to the aforementioned up and down specials.
Semi-clones
Kirby	Jigglypuff	Both share similar forward smashes, down smashes, neutral aerials, forward aerials (Kirby's hits multiple times, but he extends both legs in front of him as does Jigglypuff), down aerials, tilts, back throws, item animations, and ledge animations. Both also have near identical physics, with similar size, shape, weight, and falling speed, and both have five midair jumps (while all ten other characters have one). Their special moves, however, are all completely different.

Notes

• The Fighting Polygon Team is composed of complete clones, sans special moves, of all 12 playable fighters.
• Samus and Captain Falcon share neutral aerials, down smashes, floor attacks, forward and up tilts, and dash attacks, but have enough unique moves of their own, along with vastly different physics, to not be classified as semi-clones.
• Mario, Luigi, and Ness all share a polygon form, a neutral attack, a forward tilt and a floor recovery attack.

Clones in Super Smash Bros. Melee

The selection screen places the six clones on the far right and left, adjacent to their counterparts.

Originally, Masahiro Sakurai was going to include significantly fewer playable characters in Melee. However, with fans wanting more characters while time was constrictive, Sakurai decided to add clones later in development to pad out the roster, as these characters would take a lot less time to develop than unique characters. This led to Dr. Mario, Pichu, Young Link, Falco, Roy, and Ganondorf being added to the cast as clones. Luigi and Jigglypuff also returned, though Luigi was significantly decloned into a semi-clone, and Jigglypuff was decloned to the point of not even being a semi-clone anymore.

Original	Clone	Differences
Mario	Dr. Mario	While all attacks have identical animations, many of them have different properties. Forward smash lacks a sourspot while dealing electrical damage, neutral aerial is a sex kick that gets stronger over time, and forward aerial is very strong but does not meteor smash. Dr. Mario's attacks are also much stronger in general. Note that they also share identical physics with the exact same size, shape, weight (not in PAL regions), and falling speed, though interestingly Dr. Mario has faster air speed. Mario can wall jump, but Dr. Mario cannot, and Dr. Mario's hurtbox is slightly larger.
Link	Young Link	Like the Mario/Dr. Mario pair, while all animations are essentially identical, some attacks act differently. Young Link's forward smash has weak, set knockback on the first hit and only combos into the second hit, while his arrows are on fire and his Spin Attack is a multi-hit move when grounded. Young Link also has some slightly different physics (faster running speed, higher jumping height, and much slower fast falling speed), and is generally a faster character with weaker attacks. Young Link is also a smaller character and can wall jump.
Fox	Falco	All attacks have near-identical animations and functions, though many have had their knockback altered, changing which ones are good for KOing, such as Falco's forward smash and down tilt being considerably stronger than Fox's, while Fox's up smash and up aerial are considerably stronger than Falco's. Falco's special moves have identical mechanics but have changed enough that they have different applications, as his Blaster shots are laggier and make opponents flinch, his Reflector produces vertical knockback instead of horizontal knockback, Falco Phantasm can meteor smash, and his Fire Bird lacks a charging hitbox. Falco also runs slower and jumps higher than Fox while being slightly heavier, and has a single-hit spike for a down aerial.
Pikachu	Pichu	Pichu's attacks are faster than Pikachu's but are also weaker. Its up smash is a headbutt instead of a tail flip, its down smash emits no electricity while only hitting once, and its forward smash is a multi-hitting attack. Their special moves, while identical in name and animation, have some differences, as Pichu's Skull Bash can be charged longer and gain more power, Thunder is a multi-hitting attack, and Agility travels further than Quick Attack, while not having hitboxes and being slower. Pichu also can wall jump and damages itself for every electrical attack it uses.
Captain Falcon	Ganondorf	While most attacks have near identical animations, many of them are carried out more slowly for Ganondorf, with many having altered functionality, and most if not all attacks being overall stronger. Ganondorf's forward aerial is unique (with an overhead punch instead of a knee) and has only one, powerful hitbox, and Ganondorf's up tilt is radically altered to a point where it can be considered unique, where Ganondorf "charges" with his leg up while smoke is generated, before crashing it down in a large and extremely powerful explosion. Ganondorf's jab is only a single attack while Falcon's has three plus an infinite. Other moves possess differences in functionality. Ganondorf is heavier and has a surprisingly higher ledge jump, but the rest of his physics are overall slower than Falcon's, with Falcon having space animal physics and wall jumping capabilities. This is the only clone pair in the entire series where neither character comes from the same universe.
Marth	Roy	As Roy's sweetspot is at the hilt of his sword instead of the tip as with Marth's, even attacks that appear to be unchanged in animation and function (that is, almost all of them) must be used differently. Non-sweetspot differences include Blazer being a multi-hit move with set knockback, Counter having a multiplier for determining the strength of the counter strike (as well as a different counter strike animation), Roy's jab consisting of one hit only, Roy's down tilt hitting opponents vertically instead of semi-spiking, and Roy's up smash being a multi-hitting move. Roy's physics, while similar to Marth's, also have some differences, such as Roy falling faster with a shorter jump. This is the only clone pair in Melee where both the original and the clone are unlockable characters. Roy is also slower and weaker overall.
Semi-clones
Mario	Luigi	Luigi's many changes from Smash 64 to Melee have distanced him from Mario considerably. In addition to his previous differences, he now has a unique forward smash, up tilt, down tilt, neutral combo, forward aerial and side special; his other specials have also been further tweaked, such as the Super Jump Punch going straight up and no longer giving horizontal distance. Additionally, Luigi's down smash and neutral aerial have been altered to hit vertically while Mario's hit horizontally, and Luigi's down aerial consists of one strong hit (that can also meteor smash), while Mario's is a multi-hitting attack.

Notes

• In the transition from Super Smash Bros. to Melee, characters like Jigglypuff and Captain Falcon have been differentiated with new attacks. In Jigglypuff's case, it has kept some of its moves from Smash 64, while Kirby has received new ones.
• As Luigi and Dr. Mario share a "parent" in Mario, it stands to reason that both of these "child" clones are technically semi-clones of each other.
• Samus, Captain Falcon, and Ganondorf all share floor recovery attacks, and have dash attacks that are shoulder blocks and up tilts that are some form of axe kick.
• Bowser and Giga Bowser are clones with identical movesets, although most of Giga Bowser's moves have additional effects along with altered knockback.
• Each clone character's stock icon faces the opposite direction from their original character's stock icon, including that of Giga Bowser. This follows how Luigi's sprite faced the opposite direction than Mario's sprite in the original Super Smash Bros.
• The Male and Female Wire Frames are clones of Captain Falcon and Zelda, respectively. They lack special moves, however, and their moves lack any special effects that Falcon's and Zelda's equivalent have, such as electricity and flame.
• Master Hand and Crazy Hand can be considered clones, as they share most of their attacks.
• When deciding a clone for Mario during development, Wario was considered; ultimately, Dr. Mario was chosen instead.

Clones in Super Smash Bros. Brawl

Among the Melee clones, four were completely cut from the roster (Pichu, Young Link, Dr. Mario, and Roy). The two clones that returned, Falco and Ganondorf, were significantly decloned to being semi-clones. Luigi was also slightly decloned further, though mostly through Mario being given new attacks. Among the 18 new playable characters, none are full clones, with Toon Link and Lucas being semi-clones.

Original	Semi-clone	Differences
Mario	Luigi	The main new difference is Mario Tornado changing from Mario's down special to his down aerial, which makes two more of their attacks completely non-cloned. For some additional new differences, Luigi's up smash has a clear sweetspot and sourspot hitbox while Mario's is the same strength throughout, Luigi has a slight tweak in animation of his neutral aerial, and Luigi's up aerial hits vertically while Mario's hits horizontally. Luigi's down smash also has an updated animation as well, distinct from Mario's. Other previous similarities/differences not addressed still apply in Brawl. For an aesthetic change, Luigi has for the first time been given his own voice, instead of reusing sped-up versions of Mario's voice clips. Luigi's general animations have also been differed from Mario's, most notably his helpless animation.
Link	Toon Link	One of the more disputed pairs, as some players believe they have enough similarities to be considered clones rather than semi-clones. Toon Link's unique attacks include his up smash, neutral aerial, forward aerial, back aerial, forward throw, and back throw, while his down aerial is a stall-then-fall that meteor smashes, and his forward smash functioning like a multi-hit smash, despite both having similar animations to Link's counterparts. Other moves of theirs have function differences: Toon Link's down tilt hits horizontally while Link's hits vertically and meteor smashes, Toon Link's dash attack semi-spikes and trips while Link's hits vertically, and Toon Link's down smash functions as a multi-hit attack while each slash in Link's is individually powerful. For an additional oddity, Toon Link's forward throw was not programmed properly (Toon Link's forward throw is considered a Leg attack like Link's even though it is a shoulder tackle). However, they are completely different in their physics and other statistics, such as size, shape, weight, and walking/dashing/falling/air speed.
Fox	Falco	Falco now has a different dashing animation, neutral combo, up tilt, forward smash, neutral aerial, forward aerial, and up aerial, while Fox was given a different back aerial. Both Fox's and Falco's down throws were altered, where Fox's hits opponents far away diagonally, while Falco's hits opponents a short distance horizontally. Falco's down special now involves him kicking his Reflector, which can also trip opponents. Additionally, Falco's physics were altered, where he falls slower with faster air speed and less gravity in comparison to Fox (though their physics are still similar). Other similarities and differences that existed in Melee not addressed here still apply in Brawl.
Captain Falcon	Ganondorf	Ganondorf's forward tilt, down tilt, up smash, up throw, and side special are now unique, along with other attacks receiving an alteration in animation, such as Ganondorf's dashing, rolling and crouching animations, up tilt, forward throw, down aerial, Warlock Punch, Dark Dive, and Wizard's Foot. His Final Smash is also unique, where he transforms into Beast Ganon. Captain Falcon's down aerial is also now different, with a shorter duration and gained a hitbox that launches at the Sakurai angle. However, other standard attacks, such as forward smash, up aerial, back aerial, back throw, down throw, and their special moves outside their side special and Final Smash remain identical or near identical in function. Other differences they had in Melee not addressed here still exist in Brawl.
Ness	Lucas	Lucas's standard attacks are unique with the exception of his down tilt, forward smash, and up aerial (while the down tilt has a different animation, and Lucas's forward smash utilizes a different type of weapon, they are identical in function to Ness's). Their special moves however, are very similar in name, appearance and have similar mechanics, but differ functionally. PK Freeze freezes opponents instead of being a very powerful vertical KO move like PK Flash. Lucas' PK Fire differs to the point where it can be argued to not be cloned, as it is a single hit projectile that knocks opponents away, while Ness' hits multiple times and traps opponents (additionally, Lucas fires his PK Fire with a different animation, and Ness can fire his down diagonally in the air). Lucas' PK Thunder can go through opponents while Ness' cannot, and his PK Thunder 2 is a multi-hitting move, while Ness' hits once. However, while the similarity in their moveset can be argued to not be quite enough to label them as semi-clones, they have very similar physics, with them having identical size, shape, weight, and falling speed. They additionally both suffer from 10 additional frames of lag when being grab released that no other characters in Brawl suffer from. Weirdly, Lucas (the semi-clone) is a starter character, while Ness (the original) is unlockable, rather than the other way around as with most clone pairs.
Other
Fox	Wolf	Wolf's status is very unclear and has been heavily debated amongst the community ever since Brawl's release. Some see him as a semi-clone (or even a full clone) of Fox due to their special moves and Final Smash being mostly identical in operation, while others say he is not any sort of clone as almost all his standard attacks are vastly different. However, Wolf is unlike all other potential clones/semi-clones in that the vast majority of his non-attack animations (such as dodges, getups, and item actions) are exactly identical to Fox's - for all other derived characters, the opposite is true, where their attacks are the same and their other animations are more likely to be unique. As a result, compared to the rules that work for the rest of the roster, Wolf does not fit well into any particular category.

Notes

• The Alloys are all clones (sans special moves): Red Alloy of Captain Falcon, Blue Alloy of Zelda, Yellow Alloy of Mario, and Green Alloy of Kirby.

Clones in Super Smash Bros. 4

Super Smash Bros. 4 reintroduces full clones, adding two new clones, Lucina and Dark Pit, and one returning clone from Melee, Dr. Mario. These clones, unlike the Melee clones, were originally developed as alternate costumes of the characters they were cloned from, similar to Alph and the Koopalings. Later in development, they were given moveset alterations from their originals—according to Sakurai, Dr. Mario had to have the differences from Mario he had in Melee in order to avoid disappointing fans of his previous appearance, Lucina was given no tippers to act as an easier-to-play version of Marth, and Dark Pit was given a different Final Smash, as Sakurai did not like the idea of him using the Three Sacred Treasures. Once these changes were made, however, it was decided that they each would be promoted to full characters, as "even a small difference in abilities" requires a unique roster slot. SSB4 groups these clones in their own area together on the character select screen, rather than placing them with their respective franchises.

None of the newcomers are semi-clones. Luigi, Falco, Toon Link, and Ganondorf return as semi-clones, though they were only minimally decloned. Wolf, whose moveset was partially derived from Fox, was cut from the roster, while Lucas and Roy return as DLC. Roy is now a semi-clone, as his moveset is further distinguished from Marth's.

Most clones and semi-clones also share at least one custom move, though full clones (Dr. Mario, Lucina and Dark Pit) have more custom moves in common.

Original	Clone	Differences
Mario	Dr. Mario	Dr. Mario is largely unchanged from his appearance in Melee, but due to changes to Mario in Brawl in his absence, he is now slightly less of a clone. This includes retaining the Dr. Tornado as his down special and keeping his drill kick down aerial. New differences include much slower movement speed (fulfilling his design intention in Melee of being a "slower but more powerful Mario") achieved through the use of multipliers, a Super Jump Punch that only hits powerfully once and produces no coins at all, and a completely different entrance; on the other hand, he can now wall jump like Mario (removing a difference), and his new Final Smash is a fully-cloned move, simply using giant Megavitamins instead of fireballs. In addition, all of his custom moves are shared with either Mario or Luigi. Unlike Mario's Fireballs, Dr. Mario's Megavitamins are not absorbable.
Marth	Lucina	Marth and Lucina share effectively all the same animations, normal attacks, special moves, custom moves and attributes. Aside from Lucina being negligibly shorter, the only differences between them is that the hitboxes of almost all of Lucina's attacks are equally strong across her sword, whereas Marth's are more powerful at the tip. Lucina's down aerial is an exception, whereas instead the sweetspot placing is reversed. Lucina also has a different, more exaggerated charging animation for Shield Breaker, and has a faster dashing animation; however, this is purely aesthetic. Notably, Lucina is the first female clone introduced in the series.
Pit	Dark Pit	Both characters use the same animations and weapon types for all attacks, and almost all attacks are functionally the same, even dealing the exact same knockback with the exact same frame data. Additionally, Dark Pit's attributes, much like Lucina, are completely identical to Pit's. The few differences are Dark Pit having a smaller hitbox on his jab's rapid finisher, his forward tilt dealing weaker knockback, the arrows fired from his neutral special traveling with less control but being stronger and faster, and his side special dealing electrical damage with stronger knockback while hitting opponents at a horizontal trajectory. He also has a unique Final Smash from Pit—though it is cloned from Zelda and Sheik's Light Arrow. Notably, Dark Pit is the only clone who is so similar to his base that multiple tier lists do not give him his own placing, instead simply having him share Pit's spot. Additionally, Pit can activate Palutena's Guidance on Palutena's Temple unlike Dark Pit.
Semi-clones
Mario	Luigi	Luigi has a new down throw, where he throws opponents downwards and ground pounds them. He also has a new jumping animation that differs from that of his brother, now being his scuttle jump, and new animations for his first two jabs. Luigi does not share any custom moves with Mario, although one fireball variation makes his fireballs act like Mario's default ones.
Link	Toon Link	Link now has a new dash attack, being his jump slash, his up aerial has an altered animation, and his backwards dodge is now his back flip from Ocarina of Time. Toon Link's Spin Attack now produces green attack trails, and has a new edge attack where he rolls onto the edge and swipes his sword at the ground. Toon Link's down aerial now goes through opponents instead of bouncing on them like Link's. All of Toon Link's custom moves are distinct from Link's, except for Quickfire Bow/Piercing Arrow which is shared between them, though the charging speed, range, and hitting animation are different.
Fox	Falco	A few of Falco's moves were altered; his up smash has an altered animation and now hits twice, Falco flips on the horizontal axis when using up aerial, and his back aerial is a new move, being a backward kick similar to Wolf's back aerial. The latter two moves however were no longer cloned in Brawl, so these changes did not affect Falco's cloned status. No custom moves are shared, although one Blaster variation makes Falco's blaster act like Fox's default one and vice versa.
Captain Falcon	Ganondorf	While Ganondorf did not receive any new moves, he did receive minor functional and animation changes that further distinguish him from Captain Falcon. His grounded Warlock Punch and dash attack received some super armor and invincibility, respectively. Ganondorf's pivoted forward smash no longer has extra reach. His down smash now flips opponents. Dark Dive and Warlock Punch were also further decloned in animation. On the other hand, his down aerial and neutral aerial now behave almost exactly like Captain Falcon's, albeit with the latter having no set knockback on its first hit and an added hitbox on the foot with increased knockback. Captain Falcon's up aerial now deals vertical knockback like in the original Super Smash Bros, and his down tilt now semi-spikes instead of vertical knockback, making these attacks no longer functionally similar to Ganondorf's equivalents. Unlike most other semi-clones, Ganondorf does not share any custom moves.
Ness	Lucas	Lucas retains his moveset and attributes from Brawl, with only a few changes being made to his down throw, which temporarily buries his opponent, though this is merely aesthetic. His down tilt no longer has a chance of causing opponents to trip, and unless the tip of the foot hits opponents, the move no longer semi-spikes them, which largely declones the move from Ness's down tilt. His PSI Magnet also received some changes, as the end hitbox now only hits around the shiny part of the orb, instead of the whole orb. His up aerial is no longer connected to his head, though it has an animation more similar to Ness's than in Brawl. PK Freeze is also much quicker than all three variants of Ness's PK Flash, since it falls faster, covers more horizontal distance, and does not fully charge before it touches the ground. Additionally, his PK Freeze does not have fixed knockback, unlike Ness's PK Freeze. He also shares some extra animations with Ness despite having unique ones in Brawl, such as his Final Smash animation, dash ending animation, idle animation when holding items, and his defeated/No Contest animation. Ness has several custom moves that act similarly to Lucas's default ones while Lucas, like all DLC characters, has none.
Marth	Roy	Roy has now been given a different jab, dash attack, forward tilt, up tilt, forward air, down air and forward smash, while his other moves received alterations in animation and visual effects. Roy retains his neutral special's overhead slash from Melee, but it can now be considered unique due to the radical alterations to Marth's Shield Breaker beginning in Brawl. Roy's up special, Blazer is now performed while holding his sword with a reverse grip and can be angled, unlike Marth's. However, Roy's Double-Edge Dance no longer has exceptional knockback on the forward third hit, meteor smash hitboxes on the upward third hit, and multi-hitting properties on the low third hit, removing a difference, and as of Brawl, Marth's Counter works on a multiplier as well, albeit by a lesser factor. Roy's physics are also different from Marth's; he possesses faster air and dashing speeds, although with a much faster falling speed compared to Marth. None of Marth's custom moves even remotely function similarly to Roy's special moves. His Final Smash, while sharing the same name and retaining the same HP bar visual overlay, is also unique, where instead of dashing forward to deliver an instant KO, Roy stands in place spinning his blade around before slamming it downwards to deliver a massive fiery explosion.

Notes

• As of Smash 4, Luigi's position as semi-clone of Mario is heavily debatable, as the characters' physics are noticeably different, over half of their standard and special attacks are unique, and even several of their shared moves have different hitbox placements and function differently from each other.
• As Luigi and Dr. Mario, as well as Lucina and Roy, share a common "parent" character in Mario and Marth respectively, both pairs can be considered semi-clones of each other.
• Many standard and special attacks of the Mii Fighters are cloned moves from existing characters. Several of the Mii Gunner's moves are similar to Samus's or Fox's (with a couple similar to Ness's and Robin's). Similarly, the Mii Swordfighter shares moves with the swordsters (specifically Link and Ike), while the Mii Brawler shares moves with Mario, Little Mac, and Captain Falcon.
• The Fighting Mii Team operate like Mii Fighters but lack special moves, much like previous enemy teams.

Clones in Super Smash Bros. Ultimate

Full clones are now labelled as Echo Fighters (ダッシュファイター, Dash Fighter). These characters have movesets that are based on those of pre-existing fighters, and possess very similar if not identical proportions as well. Unlike simple alternate costumes like Alph and the Koopalings, these fighters can have unique entrances, stances, idle poses, taunts and victory poses, as well as visible gameplay differences, such as Lucina's sword lacking a tipper, or Dark Pit's Electroshock Arm dealing electric damage and launching at a different angle. Some Echo Fighters also have completely different moves from their parent characters, such as Chrom having Soaring Slash as an up special instead of Blazer.

Echo Fighters are marked with an epsilon (ε) internationally and a prime symbol (′) in Japanese added to the number of their parent fighter on the character numbering system (in Japanese, the prime symbol is pronounced "dash," hence the term "Dash Fighter"; in mathematics, the prime symbol is used to designate that something is derived from something else, for example x′ would be derived from x).

Dark Pit and Lucina are the only returning characters to be marked as Echo Fighters, while Dark Samus, Daisy, Chrom, Richter and Ken are added as new Echo Fighters. Some characters that were previously officially clones, such as Dr. Mario and Pichu, are not treated as Echo Fighters.

In the August 8th, 2018 Super Smash Bros. Ultimate Direct, it was revealed that players can choose whether all Echo Fighters should have their own slot separate from their parent fighters or be stacked with their parent fighters on the character selection screen, in the Smash section of the Options menu. After stacking the Echo Fighters with their parent fighters, players can toggle between the the original characters and their Echo Fighters with a single button press.

In a Famitsu column, Sakurai noted that during development, Echo Fighters first receive unique taunts and victory poses, then have their remaining attributes and properties adjusted where necessary.

Original	Clone	Differences
Samus	Dark Samus	Dark Samus has has numerous different animations, with her floating in midair for her grounded movement animations. Dark Samus's attack animations that use her arm cannon have her using it without stabilizing it with her free hand. Dark Samus's Charge Beam and Final Smash have a much darker appearance. Most of Samus's fire-based attacks are changed into electric ones for Dark Samus as well. Additionally, Dark Samus's roll does not turn her into a Morph Ball either, and her up smash's hithox reaches lower, allowing her to hit most grounded opponents. Dark Samus also has a different victory theme from Samus, shared with Ridley.
Peach	Daisy	Daisy has the same moveset as Peach, but is very slightly shorter (though not to the same extent as Lucina in SSB4, whose height difference was much more significant), and she has various aesthetic differences, such as orange floral effects in place of pink heart effects, several unique animations, and her Toad having blue spots on his mushroom head instead of red ones like Peach's. Her Final Smash, Daisy Blossom, summons edible flowers as well, but is otherwise functionally identical to Peach.
Marth	Lucina	As in Smash 4, Lucina has the same moveset as Marth, but her Parallel Falchion does not have a tipper, and she has different though functionally identical animations on her Shield Breaker and Counter. She also now has a different victory theme as well, shared with Robin but not Chrom. However, Lucina's height has been changed to match Marth's, removing a difference.
Roy	Chrom	Chrom's up special is Soaring Slash, which is a faster version of Ike's Aether, albeit with a modified animation. Like Lucina, Chrom's Falchion lacks a sweetspot, doing equal damage at all parts. Unlike Roy but much like Marth and Lucina, Chrom's attacks lack a flame effect. Chrom also has his own unique Final Smash, Awakening Aether, different from those of both Roy and Ike.
Pit	Dark Pit	Dark Pit is mostly identical to Pit, but he keeps his Electroshock Arm, which deals electric damage and knocks back opponents horizontally. The Silver Bow also continues to travel faster and deal more damage while being harder to control. Dark Pit also has a unique Final Smash, keeping his Dark Pit Staff from Smash 4.
Ryu	Ken	The differences between Ryu and Ken are based on those that the two have in Super Street Fighter II Turbo. As such, some of Ken's attacks involve fire, his Hadoken is a different shape, and his Focus Attack is a kick. Some of Ken's standard attacks, including his forward smash, neutral aerial and back throw, are different from Ryu’s, most notably is the inclusion of his "crazy kicks," roundhouses that can be cancelled into his Inazuma Kick. His Heavy Shoryuken has a flame effect while hitting multiple times with high knockback as opposed to hitting once, and his Tatsumaki Senpukyaku hits multiple times though having lower knockback compared to Ryu's. Ken also runs slightly faster. Ken is also the first Echo Fighter based on a third-party veteran, as Richter was introduced alongside Simon.
Simon	Richter	Richter has the same moveset as Simon, but he has several different animations, and the fire from his Holy Water is blue as opposed to being red like Simon. Notably, Richter is the first third-party clone.
Clones and semi-clones that are not echo fighters
Mario	Dr. Mario	Cape and Super Sheet have new and distinct animations emphasizing their different hitboxes. Dr. Mario has a new down aerial attack where he stomps downwards, though the two Marios already had different down aerials in Smash 4; he also has a new back throw as well that removes the collateral hitbox.
Mario	Luigi	Luigi has new walking and dashing animations, and his backward jump and midair jump animations now have him performing fewer somersaults, similar to Dr. Mario in Melee. Additionally, Luigi now uses his Poltergust for his new tether grab, and has a grab aerial as well, though he does not have a tether recovery; all of his throws except for his down throw have been overhauled as a result. His forward tilt has a different animation which faces more toward the screen, and his down tilt is much faster, completely decloning it from Mario's equivalent move. However, his up tilt has been slightly recloned to resemble Mario's, and his traction appears to have been significantly increased.
Link	Young Link Toon Link	Contrary to most declonings, it was Link who received most of the moveset changes to differentiate him from his derivative, reflecting his overhauled appearance based off of The Legend of Zelda: Breath of the Wild, not Young Link and/or Toon Link. He now possesses the ability to pick up his fired arrows and multi-shoot them or use them as a conventional item, has replaced traditional bombs with the Remote Bomb Rune, and no longer has a hook/clawshot for a tether. He also now wields his sword with his right hand and faces the right, while the other two remain left-handed and face the left. Link also has a new Final Smash, Ancient Bow and Arrow, while Toon Link keeps Triforce Slash, which has also become Young Link's Final Smash. Link's Boomerang however, lost the gale effect, removing a difference. Young Link's neutral attack infinite now has a finisher hit, while Toon Link received a new forward smash that hits once and swings upward. All three Links now have different visual effects on their Spin Attacks.
Fox	Falco	Both characters have a new Final Smash called Team Star Fox, replacing the Landmaster from previous Smash games. Fox/Falco aims a single crosshair, calling his fellow teammates from the Star Fox team in their Arwings, who slam into any player caught in the crosshair's general area, activating a brief cinematic involving the bombardment of the caught player by Fox/Falco and his teammates. Falco's variation has a more erratic laser and flight pattern than Fox's in addition to launching opponents at a more upward angle, but is otherwise identical. Additionally, Falco's down throw has a significantly altered animation as well.
Pikachu	Pichu	Pichu has new animations giving it a bouncier feel overall. It still continues to damage itself when performing electric attacks. It retains its old neutral aerial while Pikachu receives a new one similar to that of Mewtwo.
Captain Falcon	Ganondorf	Ganondorf now uses his sword from the SpaceWorld 2000 demo in his smash attacks, giving them completely different animations and functionality from Captain Falcon's smash attacks. On the other hand, some of his moves were reverted to their Melee animations, such as his down aerial and Wizard's Foot, incidentally causing them to resemble Captain Falcon's equivalent moves once again. Additionally, Falcon Dive now resembles Dark Dive's animation from SSB4 onward.
Ness	Lucas	Ness's PK Starstorm has the meteors fan outwards, while Lucas's variant has them converge inwards. They are also assisted by two of their respective teammates (Paula and Poo for Ness, Kumatora and Boney for Lucas). Ness has a new up air and they both now grabs and pummels their opponents using PSI (still differently). Also, lucas has new back and foward animation, now their base movesets are all different.
Marth	Roy	Roy now has more fiery effects on his attacks. Shield Breaker can be angled while Flare Blade can be reversed mid-charge.
Villager	Isabelle	Isabelle has a unique neutral attack, up tilt, up smash, forward smash, down smash, neutral aerial, side special and down special. However, the rest of her moveset appears to be cloned from Villager's, albeit with different animations and altered functionality. She is faster than Villager, but lighter and floatier as well, and does not have the ability to wall jump either.

Notes

• As with Fox and Falco, Wolf's Final Smash, instead of Landmaster, is now an airstrike attack involving his team; Wolf's version is called Team Star Wolf, and it launches opponents at a semi-spike angle.
• Several of Simon's moves in Ultimate, including his up special, down tilt and Final Smash, were originally used by Richter instead. As Sakurai noted in the Super Smash Bros. Ultimate Direct of August 8, 2018, Simon arguably echoes Richter as a result. This makes Simon and Richter the first clone pair in the series where both characters use moves from each other.
• In a Famitsu column, Sakurai said that Isabelle was not made into an Echo Fighter of Villager due to the two's proportions and personalities differing; Echo Fighters, as with clone fighters in past titles, are required to have similar or identical proportions to their base fighters in order to reuse the movesets and animations of their base fighters, which Isabelle does not have. Although many of her moves are cloned from Villager, all of her animations are in fact unique.
• In the Super Smash Bros. Ultimate Direct of November 1, 2018, Sakurai noted during the part where he described Ken that Luigi (although technically a heavily decloned semi-clone as of Ultimate) is the original Echo Fighter, as he was initially introduced as a simple palette swap of Mario in 1983's Mario Bros. with identical abilities. Likewise, Luigi was originally a full clone of Mario in Smash 64.

Trivia

• Mario, Link, and Marth are the only characters to have more than one clone of them.
• Jigglypuff and Ganondorf are the only characters to have been considered a type of clone of someone outside of their series.
• There is at least one Echo Fighter based upon a character introduced in each instalment of Smash.
  • Melee has the most with 3 inspired fighters.
• Lucina and Dark Pit are the only ventrens to be Echo Fighters.
• Fire Emblem is the only series to have more than one Echo Fighter.
• Street Fighter and Castlevania are the only third-party series to have a clone or Echo Fighter.
• Because Marth and Lucina share the same physics and frame data with minimal functional differences between them in Super Smash Bros. 4, players often refer to them together simultaneously using the term Marcina.
  • Simon and Richter Belmont are treated similarly in Super Smash Bros. Ultimate, in that the term Belmont is often used when discussing both of them simultaneously.
