Pokémon Colosseum

Pokémon Colosseum, formerly known as Pokémon Stadium 3, is a starter stage in Super Smash Flash 2 coming from the Pokémon series. This stage's concept is similarly based off on Pokémon Stadium (from Super Smash Bros. Melee) and Pokémon Stadium 2 (from Super Smash Bros. Brawl), in the sense the stage can change into numerous forms based on Pokémon types.

Layout
The main hazard of this stage is its ability to change into numerous forms based on Pokémon types, which happens roughly every minute. Each form consists of a large main platform with an impassable pillar on the bottom, and the platform layout above this platform depends on the form. There is a large screen in the background that normally displays the current form of the stage and the names of the characters fighting. During a transformation into another form, a flashing image of that form will display instead.

The main form of this stage is the main form used at the start that each other form transforms back into. The main platform is green with a Poké Ball symbol in the center, and there are two small soft platforms above the main platform, with one on each side.

Bug, Steel and Ghost layouts have been seen so far.

Tournament legality
This stage is a neutral stage, due to its static, highly balanced stage layout when hazards are disabled. Some players even argue that the stage is more balanced than, as there is no top platform for more vertically-inclined players to camp with.

In v0.9b, the stage was banned in online play due to lag-inducing lighting effects. However, the addition of advanced quality settings in Beta has warranted that it be legalized in all circumstances.

Origin
This stage is obviously inspired and modeled after the Pokémon Stadium stages that appear in Melee and Brawl. These stages were in turn based on the Pokémon Stadium games.

The origins of the stage's name stems from the game Pokémon Colosseum, which could be considered the third game in the Pokémon Stadium series.
