Sebek is loud, hot-blooded, and prideful. Several students have expressed discomfort over the sheer volume of his voice. Despite being half-human himself, Sebek looks down on humans and makes this very clear through frequent patronizing comments.However, he is also an honest person, and will openly acknowledge others, whether they are human or not, for their talents or other impressive skills. He is blunt and not afraid to express his thoughts. But the delivery tends to come off as rude.
