I hope someday that you will read my post. The Mortibody could fight Seifer and keep him at bay. Its Shattering Claw could severely hurt Seifer and keep him distracted long enough to give Seymour enough time to attack with some kick ass magic.

Enough of just statistcs and moves. A part of these battles are analizing the character's mind and such.

Seifer is impulsive. He is so fucking arrogant that he wouldn't take Seymour seriously. He'd blow him off and dance and shit because he has the brain of a piece of shit.

Seymour is calculating. He does not rush into a battle. He examines an enemy and configures that person's or persons' weaknesses.

With Seifer taking him lightly and Seymour observing all Seifer's faults, Seymour could easilly win.
