ops, I haven't did that but I still could defeat him (after 64782089 tries)

Freya, Steiner, Garnet and Zidane. Zidane lvl 77, Garnet 46 (lol O.o), Steiner 67, Freya 72.

Incredible, Ozma didn't casted Meteor nor Curse in this battle, just Flare, Holy lvl 4, Death and Doomsday. The battle took forever bcuz of his/her Doomsday, I hadn't did that monsters quest... so it sucked and took me about 1 day of trying but I could do it
