Dream Eaters are new critters in Kingdom Hearts 3D that players can train and fight with. The multiplayer mini-game will use a different battle system and these fights can upgrade Dream Eaters for the main story. Nomura says the game will use ad-hoc connectivity, which means its local play.
Concerning Organization XIII, Nomura said a secret about the hooded group will be revealed. Players will see Zexion, Lexaeus, and Axel in Kingdom Hearts 3D as humans with memories of their time being nobodies. A mysterious man wearing a black coat from Kingdom Hearts: Birth by Sleep Final Mix will be in Kingdom Hearts 3D too.
