To describe him:
"Raiden of RPGs"
Yes, Raiden was whiny and was mr. i'm-so-good-because-i-completed-all-VR-training-but-since-i-don't-have-real-experience-i-suck. Yes, so Raiden (metal gear solid 2) and Tidus (FFX) does share a lot of things.

1.) has whiny, annoying voice
2.) goes into mental breakdown suddenly
3.) you fight own dad

Yeah, but this is for english FFX, because Japanese FFX has better voice (actually, perfect).
