Wakka

Wakka is a minor character in the Kingdom Hearts series, originally from Final Fantasy X.

Kingdom Hearts
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, but this one lacking the bumps and Spiran script for the word "blitzball" of the original Blitzball. Nevertheless, this makes him, out of all the Destiny Islands and Twilight Town Final Fantasy characters, the only one to use the exact same weapon as his original incarnation.

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 makes no apperance in Kingdom Hearts II, including Tidus. The two are only breifly mentioned by Selphie when she is talking to Kairi early on in the game, described as being "wrapped up in their ball game." (a reference to Blitzball from Final Fantasy X)
