FusionFall

Cartoon Network Universe: Fusion Fall is an MMORPG (Massive Multiplayer Online Role-Playing Game) in which players can enter the Cartoon Network Universe as an original character in the fight against Fuse and his army of Fusions. The game announced in mid-2007 and set for release in the summer of 2008, but was delayed until January 14, 2009. The game features elements and characters from many Cartoon Network original series redesigned in an anime style by Midori Foo.

It is unlikey Gumball and Darwin will have NPCs due to the fact that the FusionFall art designer says that it is harder to make animal NPCs than Humans, stating why a character like Lazlo from Camp Lazlo isn't in the game.
