8 Iconic Superman Villains Yet To Appear On Film
3. Mr. Mxyzptlk
It's probably for the best that Mr. Mxyzptlk has never appeared in a Superman movie.
The devilish imp from the 5th Dimension would probably have lowered the tone to nothing short of farcical, but then again, Superman III and IV did that without his help.
Although Mr. Mxyzptlk is often used for comic relief, winding the Man of Steel up something rotten with his repertoire of mysterious tricks, he's actually one of the hero's oldest super-powered foes, the pair first crossing paths in 1944.
What's more, he's can claim to have been more successful than most at thwarting Supes, since his powers have their roots in magic - the only thing besides Kryptonite and a punch from Doomsday that can bring the Man of Tomorrow to his knees.
