I've gotta check the bestiary, but I don't recall someone *that* difficult in Omega Ruins... my biggest problem usually comes from Master Tonberry and the Great Marlboro. However, I've been working on building some customized armour to deal with the Marlboro. I figure once I get strong enough (my average offensive statistics are at the 80--90 level at the moment) I'll be able to handle the Tonberry.
