Awesome Moments: Reading Rawhead getting his comeuppance at the hands of an angry mob of Muggles is pretty satisfying.
Complete Monster: Rawhead Rex himself is a monster from the days before Christianity, released from the Earth in a small English village. Rawhead promptly dispatches the man who dug him out and sets about trying to regain his kingdom. The first thing he does is to murder a farmer, eat the man's little daughter alive, and kill the man's wife before attacking a police car, castrating the survivor of the crash and then burning him alive. Rawhead corrupts the local verger and hideously mutilates the reverend out of contempt for his "weak" religion. At the story's climax, Rawhead attempts to burn down all of Zeal in his fury. Unlike many literal monsters, Rawhead is a sapient being that amounts to a brutish bully who loves carnage, pain and especially eating children.
