Peter Nicols

An evil and possibly insane student at Sunnydale High who tried to sacrifice Cassie Newton to the demon Avilias. Buffy saved Cassie and killed Avilias (though Cassie died of a heart attack later, anyway), but not before Avilias bit Peter's neck, causing him to bleed. As punishment for what he had done, Buffy and Spike made no effort to help him, helping Cassie instead, and Peter presumably bled to death because of this. He appeared in Help and was portrayed by Zachery Ty Bryan.
