[1] Professor William Omaha McElroy is an Egyptologist at Yale University who suffers a blow to the head during a student riot that causes him to develop amnesia and believe he is a reincarnation of Tutankhamun.
Ever since, he has made several attempts to conquer Gotham City and defeat Batman, Robin, and later Batgirl, only to suffer more blows to the head that revert him to his original personality before he can succeed.
Throughout his appearances, King Tut's plans to take over Gotham have involved ancient scarab beetles capable of creating a mind control potion; gaining assistance from two Yale students who suffered their own blows to their heads and believe themselves to be King Tut's royal jester and Lord Chancellor; masquerading as a crime predictor and claiming Bruce Wayne is Batman while attempting to secure a scroll that will lead him to a god statue; and joining forces with Dr. Cassandra Spellcraft and Cabala, among other supervillains, in a bid to take over Gotham City in exchange for being allowed to rob Gotham's museums.
A depiction of King Tut, Victor Goodman, made his DC Comics Universe debut in Batman Confidential #26 (April 2009), and was created by Christina Weir, Nunzio DeFilippis, and José Luis García-López.
After Batman goes through a complicated Egyptian puzzle set up by Tut, the Riddler decides to quit and leaves, thinking about the advice Luthor gave him.
