The Colosseums are... The Gateway Colosseum, the Main Street Colosseum, the Waterfall Colosseum, the Neon Colosseum, the Crystal Colosseum, the Sunny Park Colosseum, the Magma Colosseum, the Sunset Colosseum, the Courtyard Colosseum, and the Stargazer Colosseum.
They might be banned or you haven't completed the game.

The final Colosseum is the Deep Colosseum after the Game, Pokemon here are Level 60-65, this is where you can catch the Pokemon you missed from the Admins earlier and a Shadow Shuckle.
if you can connect colosseum to a gba, then trade the Pokemon to the gba game and migrate!
You can only unlock it by transfering a deoxys from a Pokemon DS or DSI game.
Colosseum is a game for the Nintendo gamecube.
