Kaible
A blue-eyed, horned, clawed 7-foot monster wearing a holy symbol that looks like a Star of David with a cross. His human version is Greg Marx, who is fast, but not tall or strong.
Greg Marx is like a demon who can't do push-ups.
He ran by me like a demon, but he couldn't even touch the ceiling.
He's a demon in human form, but he can't even lift his own coffee cup.
