Story
The Space Coliseum is the final area visited by the party as part of the Dark Erde Kaiser sidequest in the post-game. In order to reach it, the player must have defeated the bosses at the Desert, Factory and Heaven's Ruins and have taken Sequencer D from Segment File 12. The party then must head to the Desert and activate the multi-colored Forbidden Device located there. At the Space Coliseum, the Professor and Dark Professor confront each other and the Dark Professor summons the Dark Erde Kaiser, which the party must fight. After it is defeated, the Dark Professor admits defeat but states there are even more powerful enemies out there, which unlocks Baal Zebul, Phobos Rigas and Mikumari.
