Pokémon Stadium

Pokémon Stadium is a Pokémon stage in Super Smash Bros. Melee located in Kanto. 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 on regular intervals it will change into one of four different terrain types: Water, Fire, Rock, or 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. Unlike the stage Pokémon Stadium 2, no Pokémon appear in any of the different forms the stage changes into.

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 Pikachus.

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.

In Super Smash Bros. Brawl, there is a similar stage, called Pokémon Stadium 2 that is just a enhanced version of this stage. The original is also unlockable.
