Kuja is just amazing like that, or something. Firion actually found a use for Straightarrow, too, as utterly bizarre as that sounds. But yeah, Kuja is so broken there.

Mega Flare is considered long-range, but it's most fun if you blast someone in the face with it and smash 'em into a wall. There's no charge-up time, you just hit 'em good and hard. It's one of those attacks that hits for an extended period before the big blast, so you pin 'em to the wall and annihilate their sorry butts.
