Mr. Mxyztplk

Mr. Mxyztplk is a mischievous imp from the Fifth Dimension who repeatedly travels to Superman's world to cause magical chaos and mischief, tormenting the Man of Steel with reality-bending pranks that can only be stopped by tricking him into saying his own name backwards.

Few characters in comics history can claim a Golden Age pedigree quite like Mr. Mxyztplk, who burst onto the scene in 1944 courtesy of the legendary duo Jerry Siegel and Joe Shuster. This imp of the funny pages has kept remarkable company across more than seven decades of publication — sharing adventures with Superman, Clark Kent, Lois Lane, and even Batman and Bruce Wayne — a roster that puts him squarely at the heart of comics' most iconic stories. Appearing across Action Comics, Superman, and The Menomonee Falls Gazette, his presence spans a breathtaking 72 years, a testament to the enduring appeal of a Golden Age original. Whether you're a seasoned collector or just discovering the deep roots of the Superman mythos, Mr. Mxyztplk is a delightful reminder that some characters cast a very long shadow from a very memorable debut.
