Mr. Mxyzptlk (roughly pronounced Mix-yez-pit-lick) is a supervillain in DC Comics' Superman comics.

Introduced in Superman #30 (September 1944) as "Mr. Mxyztplk", he was an imp from the fifth dimension. Not being bound by our physical laws, he could do things that seemed to be magical. He claimed to be a jester in his home dimension, explaining why he used his powers to play practical jokes. Superman was able to send him back to the fifth dimension by making him say his name backwards. Originally, Mxy 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, he was involuntarily sent back to his home dimenision for a minimum of 90 days. Mxy 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.

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

It was later explained that the purple-suited Mxyztplk lived in the fifth dimension connected to Earth-2 and the orange-costumed Mxyzptlk in the one connected to Earth-1. The Earth-1 version was also retconned into Superboy stories as "Master Mxyzptlk".

Mr. Mxyzptlk continued to be a thorn in Superman's side for many years. Despite Alan Moore offering a radically different interpretation of the character in Whatever Happened to the Man of Tomorrow? , he made it through the Crisis on Infinite Earths relatively unchanged, although the unpleasant nature of his pranks and the psychological effects they had on others was played up more, at least initially. In early post-Crisis stories the "condition" that would send him back to the fifth dimension was anything he wanted it to be but, since Lex Luthor taught him how to lie, making this meaningless, the stories have reverted to his saying his name backwards. Many of Mxy's later stories have a post-modern feel to them, similar to Ambush Bug, as he comments on editorial decisions, cliches of the genre, etc. This was most obvious in Superman: The Man of Steel #75, a pastiche of Superman's death in Superman (series 2) #75, which culminates with Mxyzptlk meeting the Supreme Being... who turns out to be Mike Carlin , the then editor of the Superman titles, who promptly brings him back to life.

Although Mxy does not appear in Grant Morrison's JLA, Morrison took advantage of certain similarities to tie Johnny Thunder's Thunderbolt and Aquaman character Qwsp to the fifth dimension, implying the dimension may be the origin for legends of djinn. This story also saw the first (and so far only) post-Crisis appearance of Mxy's Earth-1 girlfriend Ms Gsptlsnz (described as his "quinto-partner").

More recently, Peter David showed us Mxy's origins as a serious-minded researcher in Young Justice and, in a multipart story throughout the Superman titles, he had his powers temporarily stolen by The Joker. It has also been implied that he sees himself as serving an important purpose in teaching Superman not to take everything seriously.

He has also encountered Batman's implike tormentor Bat-Mite twice. The first was in Karl Kesel 's World's Finest book, in which they forced the heroes to compete against each other. The second was in the World's Funnest oneshot, in which they travel to various parallel Earths, including the worlds of Captain Carrot and His Amazing Zoo Crew and Alex Ross's Kingdom Come.

In recent books Mxyzptlk has been reinvented as different-sex twins, with a hatred of Superman. The reasons for this remain unknown.

Other Media

Mr. Mxyzptlk appeared in the Superfriends animated series, voiced by Frank Welker. In that series, the name was misprounced as Mix-ill-plick and he took to tormenting all the members of the team, even when Superman was absent.

In the more recent Superman: The Animated Series, Mr. Mxyzptlk was voiced by Gilbert Gottfried and his design was closer to the Golden Age version. This series also featured Sandra Bernhard as Ms Gsptlsnz.

In live action series based on Superman, Michael J. Pollard played the role in Superboy and Howie Mandel in the Lois and Clark: The New Adventures of Superman episode "Twas the Night Before Mxymas", where Mxy is said to be a leprechaun.

In Smallville there is a character called Mikail Mxyzptlk, played by Trent Ford , a young foreign exchange student who starts an underground gambling ring at the high school. Chloe is drawn into the ring and wins money on a football game, even though Mxyzptlk uses his powers to control all the players - including Clark. When Chloe discovers Mxyzptlk's secret, he kidnaps her and threatens to kill her unless Clark throws the championship game. Meanwhile, Lex threatens Mxyzptlk with deportation unless he uses his powers for Lex's benefit.
