Horror the Ancient resembles Talos of Greek Mythology. He is a large statue warrior that guards the Left Hand of Horror on the Isle of Peril. In the past, Horror was once a very fearful person and decided to magicaly channel all his fears into his left hand and cut it off so he would be forever brave. His dismembered left hand soon became the Left Hand of Horror.
This, however, did not work as planned for him because he was a "leftie" and couldn't even sign his own name.
