Sephiroth in ways is rather.. a stalking type, if he sees something he likes, he'll first collect all the info he can before making a move, something a perfectionist would do. He also loves to loathe in the fact he's powerful enough to be more than a God, it makes him so confident. However, he's mostly a pretty quiet man, decent if you get on his good side, but that won't stop him from almost using you for his needs. (Sephiroth from FF7)
