Wakka is a resident of the Destiny Islands and a friend of Sora, Kairi, and Riku. He spends a lot of time with Tidus and Selphie. He can be fought while on Destiny Islands. He uses his Blitzball to attack as he did in Final Fantasy X.

Kingdom Hearts: Chain of Memories
A memory-based version of Wakka appears in Kingdom Hearts: Chain of Memories inside the Destiny Islands simulation in Castle Oblivion.

Kingdom Hearts II
Wakka does not appear in Kingdom Hearts II, but Selphie mentions that he and Tidus are wrapped up in a ball game, most likely blitzball.
