He's actually not too hard once you figure it out... Or you can just get Omnislash, that'll make things alot easier than pairing materia and hunting down the best armor and what not.
what i never got was that there was that there was a target area(that 'orb'-ish thing in the middle bottom) that you could attack, but nothing at all seemed to have any effect at all. i mean, it didn't matter to his hit point nor to any attacks against the team that i know of, so why was it targetable? maybe something left out during the porting over to u.s.?
Bizzaro Sephiroth is way too underrated. You hardly ever see fanart of this form. I absolutely loved his theme song, maybe even more than One Winged Angel.
Wow, people calling FF VII hard. I think the whole game was too easy, even the weapons. Without KoTR and some other materias they were impossible, but with all the needed materias with nice levels they were easy as hell (and long and boring, since you cant skip summons)
This boss wasn't so much hard as tricky, because you always had a party of 3 awesome characters and maybe two underleveled losers with bad materia who invariably ended up in the same party.
