"Mister Mxyztplk" məksɪtzpʌlk was introduced as an imp from the fifth dimension. Not being bound by our physical laws, he could do things that seemed to be magical. In his first appearance, Mxyztplk wreaked havoc across Metropolis by using his powers to pull all manner of pranks. What's more, he destroyed Superman's worldview of himself. Mxyztlpk jumped out a window, causing Superman to think Mxyztlpk was committing suicide. Mxyztplk was not. An astonished Superman exclaimed "I — I thought I was the only man who could fly!!". Mxyztplk soon told Superman that he was a jester in his home dimension, explaining why he used his powers to play practical jokes.

Mxyzptlk first appearence

Originally, Mxyzptlk had designs on conquering the planet for himself, but soon settled for tormenting Superman whenever he got the opportunity. His only weaknesses were that he could not stand being ridiculed and if he said or spelled his name backwards, Kltpzyxm (kil-tip-zee-zim [kɪltɪpzizɪm]), he was involuntarily sent back to his home dimension for a minimum of 90 days. Mxyzptlk would often look for ways to counter the latter weakness, but he always proved gullible enough for Superman to trick him time and time again. In the Golden Age, saying "Kltpzyxm" would not only bring Mxy back to the fifth dimension, but would bring anyone else saying it to the fifth dimension.

Mxyztplk appeared originally as a small bald man in a purple suit, green bow tie and purple derby hat. This was changed to a futuristic looking orange outfit with purple trim in the mid-1950s, although the hat remained. At around this time the spelling of Mxyztplk's name changed (by mistake) to "Mxyzptlk"

On one ocasoin Mxyztplk is tricked into giving nearly all of his powers to The Joker.

Superman is the only who can stop him, with the help of Mxyztplk. Superman is able to stop the Joker by pointing out that fact that Batman is above him -as The Joker never kills Bat's.

This shows that even with all of Mxyztplk powers there is always a weakness like saying his name backwards.
