I stuck with the team of Lulu, Yuna and Tidus for far too many play-throughs, so I never took advantage of his usefulness until many replays later.
How foolish I felt when I saw how awesome he became so quickly.

I manage to get his STR quite high early on, so it's smooth sailing when using him in my party. Though I'm far more partial to utilizing my entire team as opposed to the one party, he's always up first along with Lulu and Yuna (retained those lovely gaiz. <3)
But yeah, those status effects are brilliant. Pity about his attire though...
