Let's say they add a Hypothetical Multiplayer Mode that is the Colosseum, who will we play as?
We know for a fact that Sora and Riku are playable, Aqua is playable in 0.2 so it wouldn't be too hard to bring her over to this game. I hope we can at most play as all of the Seven Lights.
I'd hope it would be anyone with a full move set. Similar to Days, it would be awesome to pick heroes and villains to play as. Sora, Donald, Goofy, Kairi, Lea, Axel (yes, both), Riku, Aqua, Terra, Ventus, Roxas, Terranort, Xemnas, Ansem, Marluxia, Larxene, Data/Replica Riku, Xion, Vexen, Saix, Demyx...I'm not sure if I'm missing anyone from both sides...
