If Setzers H-Bomb counts as fire, the only move that comes to mind of his that would help is the diamond one. I don't think the Chocobos hit the cranes, but I'm not very sure on that. With low levels I'm not sure if he'll be effective at al right now. I'd think you took reflect ring of Gua, as it wouldn't help much only hurt if they bounced off and powered themselves up.
