Phwillite

Phwillite was a planet that housed the Colosseum, one of many copies of Earth landmarks that was sold by the renegade Brancheerian Monty Punnions.

Professor Rulas was using the Colosseum as a giant arena where his super computer the Colossus selected 'players' in an effort to find the strongest and bravest fighters in existence by placing them in the arena to decide the champion of the universe. The Colosseum was abandoned when Rulas was tricked into becoming a competitor and shut down the Colossus in order to survive. (COMIC: Colossus of the Colosseum)
