Brutal mass murderer. Disturbed as a child, he was chosen to be inflicted with the Curse of Thorn, which focused his rage on his family and made him invincible. He has murdered scores of people, but is catatonic between Halloweens in which the Thorn constellation is present.
Michael Myers as a character was blemished by having his ass kicked by Busta Rhymes in Halloween: Resurrection.
A curse which makes the bearer invincible, but also forces him/her to kill his/her immediate family. Every once in a while on Halloween (and only Halloween), the Thorn constellation appears in the sky, signalling the followers of Thorn to curse a new person. When done, prosperity falls on the whole tribe. Michael Myers is currently cursed with Thorn, and Terence Wynn (who is currently missing) serves as his watcher. A person with allegiance to Thorn can be identified by a Thorn tattoo on their right wrist.
