Colosseum (コロシアム Koroshiamu) is a huge soccer arena in Server Continent.
The Colosseum is the location of the Crest of Sincerity. The Chosen Children arrives at the Colosseum in search of Jou's Crest, as suggested by his flashing Tag. They are then attacked by a Greymon under Etemon's control, and gets trapped under an electric cage disguised as a goal post. The Crest of Sincerity turns out to be under the ground of the cage. Agumon turns into Skull Greymon through Dark Evolution here.
