"Seifer is a loud and outspoken rebel. Although he is belligerent and rude with delusions of grandeur, Seifer is troubled rather than evil. He is twisted by the sorceress's power, and pursues a warped version of his dream, although the degree to which he is controlled or influenced by her power is left ambiguous. He has been bullying other kids since he was young and is considered a "problem child" by the Garden staff. He defies authority figures and believes that others should defer to taking orders from him. He acts impulsively, and his rash decisions get him into trouble until he feels he can no longer back out." - Final Fantasy Wiki

Voice range: Medium to Medium-Low. Serious, bossy, and raspy. He has a bit of a stick up his ass. Try thinking of raspy-voiced rival characters like Chazz From YuGiOh GX, except not cartooney.
