In Kingdom Hearts Birth by Sleep Final Mix, Illusion-B is a Friendship Command that takes up two slots in the Command Deck and has a maximum level of 3. Using Illusion-B command transforms the user into a Belly Balloon and grants them its abilities. The transformation lasts until the Illusion Gauge empties or the user uses the Revert command.
The Belly Balloon jumps on the spot when stationary and skips around to move. It performs a basic attack by shooting a jet of air from its hands at an enemy. It cannot block, but it can perform a low jump by pressing . If it takes too much damage, it overheats and rolls into enemies for a while before exploding, dealing damage and then undoing the transformation.
