Master Mxyzptlk
Master Mxyzptlk
A youthful and red-haired imp from the Fifth Dimension of Zrfff with magical abilities that easily affect Superboy. He can be forced back to his home dimension (most chronicles say for a period of one month to ninety days) if he says his name backwards ("Kltpzyxm").
Superboy first meets Mxyzptlk when the mischievous imp crosses over into our universe after running away from his parents. Meeting the Boy of Steel, Mxyzptlk decides to play pranks on him, making him a laughing stock. Superboy thwarts Mxyzptlk’s attempts, which incenses the imp. In response, Mxyzptlk creates a Jor-El ghost to convince Superboy to leave Earth. However, Superboy realizes the ghost is fake because the color blind Mxyzptlk has reversed the red and green in Jor-El’s outfit. Fuzastl, Mxyzptlk’s father, sends a message to Earth that tells Superboy how to send his son home by convincing the imp to say his name backwards. Tricking Mxyzptlk, Superboy sends him home to the Fifth Dimension. This defeat at Superboy‘s hands is the beginning of a feud between the two that lasts for several years, when the two opponents are known as Superman and Mr. Mxyzptlk (SB No. 78/3, Jan 1960: "The Ghost of Jor-El!").
Superboy also encounters Master Mxyzptlk on several later occasions (for example, SB No. 83, Sep 1960: "The Dreams of Doom!", SB No. 120, Apr 1965: "The Invulnerable Imp!"; SB No. 131, Jul 1966: "Lex Luthor, Imp!").
