Pokémon Stadium
Pokémon Stadium is a Pokémon stage in Super Smash Bros. Melee. It is based off the stadiums used during the final battles of the Pokémon series. It is also based on the stadiums used in the game Pokémon Stadium. It looks like a simple stage, with two floating platforms, but every once in a while the stage will change into one of four different terrains Water, Fire, Rock, and Grass. The stage also features a giant screen in the background showing a close up of the battle or sometimes the current leader of the match.
The stage is featured in Stage 7 of Adventure Mode, which features the player going up against several Pikachu's. After Jigglypuff and Pichu are unlocked, they will randomly appear amongst the Pikachu's.
There is also an alternate track that usually plays when Pichu is battled. It is called "Pokémon Gold & Silver", which is a combo of many of the battle themes from the said game.
The stage has been seen in a few screenshots and trailers of Super Smash Bros. Brawl, showing that the stage will return. It will still change terrain.
