Pokémon Stadium


 * Not to be confused with Pokémon Stadium 2.

After ten years, it's back! In addition to the basic stadium formation, the stage also switches between Fire, Water, Rock, and Grass variations. If you want to win on this stage, you'll have to alter your strategy based on the current formation! Announced at E3 2001, Pokémon Stadium (, Pokémon Stadium), is a stage debuting in Super Smash Bros. Melee and returning in both Super Smash Bros. Brawl and Super Smash Bros. Ultimate. It is commonly referred to as "Pokémon Stadium 1" to avoid confusion with its similar successor, Pokémon Stadium 2.

In Melee's All-Star Mode, this stage is played on when the player faces and any of its teammates.

In Melee, Pichu and Jigglypuff are fought here for their character unlock battles; in Ultimate, Pokémon Trainer is fought here for his character unlock battle.

In Ultimate, the jumbotron has a wider screen just like Pokémon Stadium 2.

Basic Version
The basic stage is symmetrical and consists of one large main platform, with two floating soft platforms above. After a varying period of time, the basic stage transforms into a random one of four variants, each based on a from the Pokémon series. After a while, the stage reverts to the basic form, and the cycle repeats. The same variant can occur consecutively. All forms have an impassable vertical pillar underneath the main platform.

In the background, a large crowd watches the fight while fireworks go off in the sky. There is a large jumbotron which can display the battle itself, a symbol representing the upcoming variation during a stage transition, or the current standings of fighters and the match timer. In Brawl, the jumbotron in the background shows the fight in a lower picture definition than in Melee, and uses a new, clearer font for its display. When the jumbotron displays the "Current Leader" in Melee and Ultimate, the font of the character's names matches that color of their player port. Additionally, in Team Battles, the color of the CPU players' names matches their respective teams color but with less saturation. In Brawl it will show only one character's name even if there's currently a tie between multiple characters for the highest score/stock count, and in Team Battles, will only display the character leading the team with the higher score rather than the entire winning team. When playing on this stage in Training Mode in Melee, the stage will not transform and the jumbotron only focuses on the battle or zooms in on one of the characters.

Grass Version
The  variant takes place in some kind of forest or park. The main platform has slightly elevated plateaus on both sides. A small stream separates the left plateau and the central area, causing a slight depression. A wooden structure with two platforms, one above the other, occupies the middle-left part of the stage, while in the right part there is a tree whose branches form a third platform.

Fire Version
The  variant takes place in a burning forest. The center of the main platform is occupied by a small depression. On the left side there is a ruined tree: players can stand on top of it, but, due to its height, often need double jumping to reach its top. From the left side of the tree stems a branch which supports a soft floating platform.

On the right side there is a burning shack, the roof of whose porch acts as another soft platform. Note that the fire in the background is purely aesthetic and has no gameplay effect.

Water Version
The  variant takes place near a pond or lake. The whole right side is occupied by a flat pond, while on the left there is a small elevated pier which slopes down on both its sides. Over the pond, two soft platforms are suspended by water spouts, the right one higher than the left one.

On the left side there is a windmill. Its arms spin slowly and can be stood upon, but players on the current lowest arm fall. The arms are soft in Melee and Ultimate but hard in Brawl. In Brawl it's possible for small items to get stuck in the windmill if one lands in the center of the windmill just as it becomes solid. Poké Balls will not activate while stuck there.

Rock Version
The  variant takes place in a canyon near a mine. Its terrain is the most uneven of all versions. The right part is flat and empty, while in the middle there are three soft platforms one above the other, of which the bottom one touches the ground and can be walked up from it.

The left side is occupied by a large solid mountain, on whose right side stem two more soft platforms. The walls it creates can cause infinites and caves of life. The top of the mountain itself acts as a solid platform. The mountain's left side is almost vertical and ends almost at the right edge of the stage, leaving a small walkable space.

Ω form and Battlefield form
In Super Smash Bros. Ultimate, the Ω form and Battlefield form are set on the default transformation of the regular form and does not transform into any of the four variants. The soft platforms are also absent. The main platform is also resized and reshaped to match and, respectively. The three soft platforms of the Battlefield form are based on the ones in the normal form.

Hazards Off
With hazards off in Ultimate, the stage remains in the Basic Version for the whole match.

Origin
While the stage is not specifically based on anything from the video game series, it may be a general representation of a. A possible specific origin could be the Pokémon Stadium games, from which the stage's name possibly comes from and whose arenas in-game feature a Poké Ball logo in the middle, a crowd watching the battle and, in the case of Gym Leader battles, type-related aesthetics. However, the arenas in the Pokémon Stadium games, including the type-themed ones, do not affect the battles in any way. Despite sharing its name with the game , the stage features no direct references to it or its sequel.

Another possible source is the  anime, in which, during tournament battles, the arena changes its terrain frequently to hinder or help either Pokémon. This was seen at least in the preliminary rounds of the, during which each of 's four initial battles was in a different battlefield representing a specific elemental type.

Melee
Pokémon Stadium was one of the few stages that people in tournaments have almost never questioned being legal, and for a long time, was a starter. Many people considered Pokémon Stadium to be one of the fairest stages in Melee because the shifting terrain was generally not very disruptive to gameplay, and for some time, was thought to prevent excessive projectile camping. However, recent metagame developments have shown that and  have a very large advantage on this stage because the geometry of the stage and terrain allow them to projectile camp with Blaster very safely. It is also the only legal stage with walls, allowing Fox to perform the drill shine infinite. The large horizontal size of the stage benefits their movement greatly, while hindering other characters who cannot traverse across the stage as easily, while the low ceiling allows even earlier KOs for Fox's two main finishers. The transformations also benefit Falco, and especially Fox, greatly in several matchups by either giving them more room to approach or safe spots to camp in.

While the long stage size, platform placement of the main stage, and low ceiling can also benefit characters with good dash dances such as and, the advantages that these characters gain pale in comparison to the aforementioned advantages realized by Fox and Falco. As such, it has been deemed a counterpick stage in more recent rulesets, with some Melee players arguing that it should even be banned because the advantages given to those two characters are too overwhelming for the majority of the cast. Many players will choose to "wait out" the Fire and Rock transformations by moving to the opposite side of the stage as their opponent, without approaching or attacking them, until the transformation returns to neutral. As a result, many players complain that the transformations result in several minutes of wasted time during a set.

"Frozen Stadium", a modded version of Pokémon Stadium which disables the stage transformations, has become increasingly popular in competitive play. It was first used sporadically in regional scenes, such as at, and became more widespread following the dominance of online play in 2020, as the Project Slippi netplay system uses Frozen Stadium as a default stage in unranked play. Frozen Stadium has now become widespread in offline tournaments, but is not universal, as a few tournaments, such as, have kept the unfrozen version. Supporters of Frozen Stadium argue that the removal of transformations makes the stage less randomized, more balanced, and removes the time wasting components often seen during the Fire and Rock stages. Opponents of Frozen Stadium argue that this would open up a path towards increased levels of modding and possibly the introduction of new player-built stages, making it more difficult to run in tournaments and possibly leading to legal issues with Nintendo. They also argue that stalling during the transformations should be seen as a viable counterpicking strategy, and that Frozen Stadium's layout is too similar to that of, further hurting characters who have a perceived disadvantage on both stages.

Brawl
The stage is more debatable in its neutrality; while it is a starter in the Unity Ruleset and always in seven-stage starter lists, Lylat Cruise is often chosen over it in five-stage starter lists, while never being a starter in three-stage starter lists. The change in unquestioned neutrality comes from changes to the stage itself: first, the lips at the edges of the stage are much more thin and deceptive, occasionally flustering recoveries from slightly underneath the stage or even regular recoveries away from the stage. The most notable change in the stage, however, comes from the redesigned water transformation: while it looks almost the same as in Melee, the blades of the windmill are no longer soft platforms and cannot be passed through in any direction, resulting in stage traversal difficulties and significant caves of life. Like in Melee, Brawl players tend to camp out the Rock and Fire transformations, hiding behind the large rock and the tree until the transformation has ended, slowing down gameplay and matches.

Ultimate
The stage is usually banned, as it has too many similarities to Pokémon Stadium 2 when hazards are turned off. Some regions, however, have Pokémon Stadium as a legal starter over Pokémon Stadium 2, most notably Chicago and, at one point, Maryland/Virginia. This is mainly due to some players believing the stage is a more reasonable size when compared to Pokémon Stadium 2. Opponents of this stage, on the other hand, cite several inconsistencies that make the stage more "janky" and therefore ill-suited for competitive play compared to its successor; most notably, the stage suffers from bugs that can cause players to clip inside the main platform of the stage, and prior to version, the right platform featured an invisible slant that made it impossible to perform locks over it. The stage's camera also causes the visibility of the edges to be obstructed.

With the release of Small Battlefield, Pokémon Stadium generally fell even more out of favor, as Small Battlefield could provide a significantly more compact alternative to Pokémon Stadium 2, and the need of a middle ground was not felt much by most of the community. As a result of all these factors, Pokémon Stadium is currently banned in almost every region worldwide.

Super Smash Bros. Melee

 * On the fire variant, if a character gets hit towards the right side of the tree's base, there's a chance they will fall through.

Super Smash Bros. Brawl

 * On the grass variant stage, if a character walks onto the very left where the tree stump is while it is forming, they will fall through.

Trivia

 * The icons flashing on the jumbotron, which denote the arena types, are derived from the type symbols of the, and in an early version of Melee, they looked exactly the same.
 * The icon that flashes when the stage is about to change into its Water form is the tidal wave from Japanese painter 's famous painting, .
 * Since the jumbotron takes up a large part of the stage, whenever it displays the match, the images on the jumbotron are replicated inside the projected jumbotron and so on, creating a.
 * When a player opens up the menu in Training Mode, the jumbotron will follow the game camera's zoom in on their character.
 * This is the only Pokémon stage to not feature any Pokémon in any capacity.
 * In Ultimate, if the jumbotron focuses on a character and the game is paused, the jumbotron will try to remain focused on that character if the pause camera is moved around.
 * If the pause camera is angled such that the "back" of it is towards the focused character and the camera is zoomed in, the jumbotron's image will be rotated 180 degrees and some of the pixels will be stretched to the edge of the screen. This also occurs on Pokémon Stadium 2.
 * Venusaur, along with other Pokémon, were originally planned to appear on the stage. However, this idea was scrapped, and Venusaur was instead a Poké Ball Pokémon in Melee. Background Pokémon would later be present on Pokémon Stadium 2.
 * If is currently on the stage, the jumbotron will display her name as "Samus" instead of "Zero Suit Samus". This also happens in Pokémon Stadium 2 and PictoChat.
 * This is the only past stage in Brawl to have three music tracks.
 * In Brawl whenever either this stage or Pokémon Stadium 2 is featured in an event match, the jumbotron will not display "SUCCESS" when clearing the event, but will display "FAILURE" if the event end in a failure. This was fixed for both stages in the PAL version.
 * When playing a game of Squad Strike, the names of the characters on the jumbotron will not change until it updates itself. This also happens on Pokémon Stadium 2.
 * This also happens when either adding more CPU opponents in Training Mode or swapping between and . This is unlike Melee and Brawl where the jumbotron updated whenever Zelda and Sheik transformed or Pokémon Trainer changed Pokémon.
 * In either a Stock or Stamina match, if a player slot is skipped, the jumbotron sometimes displays the wrong player number if a player loses their last life. For example, in a 3-player Smash involving P2, P3 and P4, if Player 2 gets defeated, the jumbotron displays "Player 1 Defeated" despite player 1 not being present.
 * On the left side of the background, a building with the word "POCKET" (the O being replaced with a Poké Ball) and a screen can be seen. This is likely based on the Game Boy Tower, a location that acts as a special built-in emulator (which is actually a modified version of the Super Game Boy 2's BIOS) used to play the Pokémon games inserted into the player's Transfer Pak in Pokémon Stadium and Pokémon Stadium 2. Additionally, the "POCKET" on the building is a reference to the Pokémon series' Japanese name, Pocket Monsters.
 * The following Assist Trophies can only appear on the Battlefield and Omega forms of this stage: Burrowing Snagret, Kapp'n, Arcade Bunny and Squid Sisters. Additionally, Marshadow can only be summoned on the stage's Battlefield and Omega forms.
