The Underdrome (冥界コロシアム Meikai Koroshiamu, lit. "Underworld Coliseum") is the Underworld counterpart of the Olympus Coliseum. It is where all tournaments are fought in Kingdom Hearts II.
Story
Described as a "killer" coliseum that made the one above look like "an Olympic kiddie pool", Hades had fiends of all kinds fight in the Underdrome. However, Zeus was against such senseless violence and locked the place up, hiding it beyond the Lost Road. Upon learning from Pete that the Keyblade could open ANY lock, Hades kidnapped Meg and put her in the Underdrome. With that as incentive, Sora unlocked the Underdrome and rescued her. Hades sent the heroes off to fight the Hydra, while beginning his plans to restart the games.
Sora, Donald and Goofy later return to the Underworld in their quest to find Organization XIII's hideout. They see the Underdrome and are informed by Auron that "some fool" must have unlocked it. Hades then forces the trio and a disheartened Hercules into the Hades Cup, brainwashing Auron into being his assassin. However, Sora, Donald and Goofy manage to break Hades' spell and help knock the villain into the River of Styx.
Hades later gets out, deciding to hold tougher tournament to kill Sora, Donald and Goofy. However, they mange to beat even the Hades Paradox Cup. Infuriated, Hades is kicked by Pegasus as the team celebrates.
Tournaments
The Underdrome hosts eight tournaments in all; four regular cups, and four "Paradox" cups that can only be entered by talking to Hades; the first three Paradox cups are merely reruns of their normal counterparts, except that the opponents have been empowered, while the final Hades Paradox Cup is a lengthy tournament taking elements from all previous cups.
