6. King Tut
King Tut is one of the more successful of the series original villains largely because he has the most extensive and zany backstory. William Omaha McElroy is a well-respected Egyptologist professor at Yale until, that is, he hits his head. Then he believes himself to be a reincarnation of Tutankhamun intent on becoming the pharaoh of Gotham. Until he hits his head again and then he returns to normal. Until the next time he hits his head Tut is such a popular villain from the series theres even been a recent, more serious, version of the character in the Batman comics who is derived from Victor Buenos original creation. We'd love to see the comics tackle the next villain on our list...
