Biography
Tidus is a friend of Sora, Riku, and Kairi, and is a resident of the Destiny Islands, spending most of his time with Wakka and Selphie.

In Kingdom Hearts: Chain of Memories, Tidus appears with Wakka and Selphie in both Sora and Riku's stories as part of the memory-based Destiny Islands in Castle Oblivion.

He does not appear in Kingdom Hearts II, but Selphie mentions that he an Wakka are "All wrapped up in their ball game," which, if he's anything like his original incarnation, is Blitzball.
