I think Seymour is pretty cool myself.

I mean, yeah, he's totally creepy. He creeps me out in ways that only a strange uncle you meet for the first time at a family reunion could creep me out. However, these traits of pure creepyness fit his character well.

Spoiler:
Think about it, he murdered technically both his mother and father. All of his life has been tourment for being a half breed guado-human. And he's still probably haunted by his mothers passing in the aeon that he now controlls. His personallity is supposed to be creepy so that you as the player can immedietly identify him as the bad guy. So you can get that feeling of "I knew there was something wrong with that guy from the minute I saw him." Just like Tidus did.


I just wish his boss fights weren't such a chore. (Seriously, auto-potioning body guards in one. Zombie followed by full-life in another, GIVE ME A BREAK!)
