(weapons are in order of weak to strong)

~1~ Sapphire - This one attacked Junon city when Tifa was going to be killed. You never had to fight him cuz Rufus kills it with 'Sister Ray'.

~2~ Dimond - Kills Rufus and blows up the Shin-Ra tower in Midgar. The battle you have to fight is just about as hard as fighting a lone Chocobo. Cast your strongest summons twice or once if it's KOR and you win.

~3~ Ultimate - He fly's around any place. Also he runs away in the middle of the battle all the time, but never gains back his HP. He's not tough at all. Just the hole cast strong summons and kill him like a normal big boss.

~4 & 5~ Emerald & Ruby - There are two ways to kill ether weapon click here for the #1 on Emerald ~ click here for the #1 on Ruby. And for those of you who like to kill kill kill and not really have to fight (remember- kill kill kill blood makes the grass grow/ and if you think about it in this game it really does) now my way is simple and it will work on any boss or enemy that you can same before fighting. Take Cait Sith into a battle before the big one and get his Limit filled up (Slots is the limit you want) Then have him use magic or have you r other people kill them selfs. After the battle equip him with 'Sprint Shoes' or any other item that will put him in auto-haste. Once there go to the boss and save just before the fight. When you get in the fight cast slots and if you don't get 'instant death' re-set and go back and cast slots again if you don't get 'instant death' re-set and ...well you get it. But you have to remember - if you can do it in the game with out a game shark or mod-chip then its not cheating! >^_^<
