odin is the best cause if you get daggers odins sword ability he dose more than 8k damige to necron even and bahamut dose arund 2-3k damige to anything but the weakest monsters its true later in the game most summons suck all i ever do is summon odin use holy flare and attack with zidanes ultimate weapon wich is good enught whats the point in wasting 50 mp on a move that dose 3k when you can use 20odd mp for an attack that dose 8k+ all the time or kills em with death. summon on X sucked becasue they where only about 2x the power of your 3 attakers apart from yojimbo
