Mister Mxyzptlk
Mister Mxyzptlk is a reality manipulating imp from the 5th Dimension who antagonizes Superman. Not actually evil, he does no long-term damage although he constantly seeks to pester and prove he’s smarter than the man of steel. He cannot be made to return to his home dimension until he’s tricked into saying his own name backwards “Kltpzyxm.”
