Mister Mxyzptlk

Cover to Action Comics #80 (January 1945), art by Wayne Boring.

Mister Mxyztplk (the original spelling) was introduced in the Golden Age as an imp from the "fifth dimension".[5] Not being bound by our physical laws, he can do things that seem to be magical. In his first appearance, Mxyztplk wreaks havoc across Metropolis by using his powers to pull all manner of pranks, first pretending he got hit by a truck and killed, then increasing his weight when the ambulance gets there and waking up to shock them. What is more, he destroys Superman's worldview of himself. Mxyztplk jumps out a window, fooling Superman into thinking Mxyztplk is committing suicide. When he appears unharmed, an astonished Superman exclaims "I-I thought I was the only man who could fly!!". He gives the Mayor the voice of a donkey, then blows papers over the town. Mxyztplk soon tells Superman that he is a jester in his home dimension, explaining why he uses his powers to play practical jokes. But one day he found a book which told him of this world.

Originally, Mxyztplk has designs on conquering the planet for himself, but soon settles for tormenting Superman whenever he gets the opportunity.[6] His only weaknesses are that he cannot stand being ridiculed and if he says or spells his name backwards, Klptzyxm (kil-pit-ZEE-zim /kɪlpɪtˈziːzɪm/), he is involuntarily sent back to his home dimension for a minimum of 90 days. He first gets fooled when Superman asks what the word is and he says Superman would have thought him stupid enough to say "Klptzyxm", before realizing what has happened and being transported home. Mxyztplk often looks for ways to counter the latter weakness, but he always proves gullible enough for Superman to trick him time and time again. In the Golden Age, saying "Klptzyxm" will not only send Mxyztplk back to the fifth dimension, but also anyone else who said it. To return to his/her home dimension, one has to say one's own name backwards.

Mxyztplk originally appeared 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 and white hair on the sides of his head in the mid-1950s, although the bowler hat remains adapted to the new color scheme. In Superman #131 (1959), the spelling of Mxyztplk's name changed (by some accounts through a mistake) to "Mxyzptlk".[7]

It was explained in the Silver Age Superman comics that Mister Mxyzptlk could affect Superman because Superman is susceptible to magic, which was established as a major weakness for the superhero.

When a Mxyzptlk jaunt causes a special appearance by Superman to be cancelled and children, who had done nothing to Mxyzptlk, to be disappointed, Superman himself decides to turn the tables and visit the fifth dimension (how is not explained), making trouble for the imp, who is running for mayor. For example, when Mxyzptlk furnishes a huge supply of food for prospective voters, he says, "Eat up, folks, the food's on me!" Superman uses super-breath to blow the food all over the imp and then chortles to the voters, "Like he said, folks – the food is on him!" The imp tries to get the Man of Steel to say "Namrepus" (Superman backwards) repeatedly, but when he finally succeeds, it does not work and Superman remains in the fifth dimension. Mxyzptlk ultimately loses the election, and, his mission accomplished, Superman banishes himself back to Earth by whispering "Le-Lak" (his Kryptonian birth name Kal-El backwards).[8]

After the establishment of DC Comics' Multiverse in the 1960s, it was later explained that the purple-suited Mxyztplk (the "t" and "p" are transposed to slightly alter the name) lives in the fifth dimension connected to Earth-Two and the orange-costumed Mxyzptlk in the fifth dimension connected to Earth-One. The Earth-One version is also retconned into Superboy stories as the young red-haired Master Mxyzptlk, who bedevils Superboy during his youth in Smallville. He even appears as a deus ex machina to stop the Kryptonite Kid, who was killing a helpless Superboy, so that he could continue to bedevil Superboy and, later, Superman.

A 30th-century descendant of Mxyzptlk appeared in Adventure Comics #310 (July 1963) with similar abilities. Much crueler than his ancestor, this version kills most of the Legion of Super-Heroes until Superboy tricks him into falling victim to the same "Kltpzyxm" weakness, reversing the effects of his magic. However, in another story from Adventure Comics #355 (April 1967) featuring the 30th-century Adult Legion, the brother of the cruel Mxyzptlk teams up with a descendant of Lex Luthor to save the Legionnaires from the Legion of Super-Villains and join the Legion themselves.

Alan Moore offered a radically different interpretation of the character in the 1986 two-issue story Superman: Whatever Happened to the Man of Tomorrow?, a possible end of the adventures of the Earth-One Superman. Mister Mxyzptlk (appearing in darker colors and looking more sinister than in the past) explains that the problem with immortality is finding ways to spend the time. He spent his first 2,000 years without moving or breathing, the next 2,000 years doing only good deeds, and the following 2,000 years being the mischievous character that he is normally portrayed as. He has now decided to try being evil, and is responsible for all of the nightmarish events in the story (also musing that after 2,000 years of evil, he may spend the next 2,000 years feeling guilty). Before attacking Superman, he reveals his true form, which is described by Lois Lane as having "height, width, depth, and a couple of other things." He is killed when Superman sends him to the Phantom Zone at the same time that Mister Mxyzptlk begins an escape to the fifth dimension by saying his name backwards voluntarily, tearing him in two. Despite having recognized that his foe was too dangerous to be stopped any other way, remorse over the killing prompts Superman to drain himself of his powers using gold kryptonite.

Another final appearance of Mister Mxyzptlk was in the final issue of DC Comics Presents, which shows Jor-El's discovery of the Phantom Zone. By the end of the story, the Phantom Zone, the fifth dimension and the Bizarro World are all destroyed, and Mister Mxyzptlk, infilled by power endowed by a hideously disfigured wizard who was a denizen in the Phantom Zone, is transformed into an entity not even remotely human. He then throws the dead Argo City into Metropolis, littering it with tons of kryptonite and dead Kryptonians, and announces to an exasperated and horrified Superman that this was his last jest, that he will never be able to top it, and so says farewell to Superman.

Mxyzptlk made it through the Crisis on Infinite Earths relatively unchanged, although the unpleasant nature of his pranks and the psychological effects they have on others is played up more, such as when he animated the Daily Planet building heedless of the occupants inside who were being violently thrown around with its movements. He also began smoking cigars, symbolic of his newer, more antagonistic nature. His first appearance in this new continuity saw him initially adopting the guise of "Ben deRoy", an omnipotent mystery man resembling the Beyonder, who was threatening the Marvel Universe around the same time. He resumed his more familiar appearance when he was confronted by Superman.

In his first Post-Crisis story, Mxyzptlk played the "Name Game" with Superman, with saying or writing his name backwards sending him home. However, in his next appearance, this has no effect; the "condition" that would send him back to the fifth dimension would be anything he stated it to be for the occasion, and the act itself would not banish him, but instead be Mxyzptlk abiding by his own terms. After his first encounter with Lex Luthor taught him how to lie, Mxyzptlk began rigging his contests with false or misleading aspects to make his challenges greater. Ultimately, the stories reverted to Mxyzptlk having to say his name backwards to get him to leave.

One of Mxyzptlk's most prominent storylines in the new continuity was the "Krisis of the Krimson Kryptonite" storyline, when he provided Lex Luthor with a sample of red kryptonite that took away Superman's powers so long as Luthor never revealed to Superman that Mxyzptlk was involved. Despite Superman's lack of powers, he still risked his life to battle Mammoth and the mad scientist Thaddeus Killgrave. Eventually, the spell was lifted when Luthor told "Clark Kent" where the red kryptonite had come from, believing that he would not be breaking Mxyzptlk's rule about not letting Superman know the truth if he told Kent and Kent told Superman (in a one-page aside in this story, Mister Mxyzptlk is implied to also be the Impossible Man, spending his off-time badgering the Fantastic Four of the Marvel Universe).

Many of Mxyzptlk's later stories have a postmodern feel to them, similar to Ambush Bug, as he comments on editorial decisions, clichés of the genre, etc. This was most obvious in Superman: The Man of Steel #75, a pastiche of Superman's death in Superman (vol. 2) #75, where Mxyzptlk creates a duplicate of Doomsday. The confrontation 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 Mxyzptlk does not appear in Grant Morrison's JLA, Morrison took advantage of certain similarities to tie Johnny Thunder's Thunderbolt and Aquaman's nemesis Qwsp to the fifth dimension, implying the dimension may be the origin for legends of djinn. This story also saw the first Post-Crisis appearance of Mxyzptlk's Earth-One girlfriend, Ms. Gsptlsnz (described as his "quinto-partner"; pronounced Giz-pit-lez-nez or "Gizbie" for short).

In 2001, DC published Bizarro Comics in which Mister Mxyzptlk fought an all-powerful entity named A who is conquering and wrecking dimensional worlds—including the 5th dimension—by use of toys and games. Mxyzptlk retains the services of a version of Bizarro who calls him Greg, and pads the story out by writing and drawing 27 off-beat stories using the DC superheroes, taking 160 pages. Bizarro is in two of them. Also of note is the depiction of Bahdnesian thunderbolts and Zook's species as native to the fifth dimension.

In Countdown to Final Crisis, the modern Mxyzptlk claims to have always felt the need for a "public" in the third dimension and that Superman was not his first victim.

In Young Justice #3, Peter David showed Mxyzptlk's origins as a serious-minded researcher, who travels through time, summoned by computer-based occultists. He takes the opportunity to conduct some scholarly studies. He chooses to examine a Halloween party in Happy Harbor, focusing on the results of aging a portion of the teens and causing some of the others to frantically dance out of control. What Mxyzptlk does not know was that Robin, Superboy, and Impulse were hired by the town's adults to chaperone the party. When the boys confront Mxyzptlk, they realize that this was not the same Mxyzptlk whom Superman had regularly faced; indeed, he appears to not have even assumed the name "Mxyzptlk" at this point, regarding it as sounding like something somebody randomly typed (which is, indeed, how the character chose his name in his first Post-Crisis appearance). Upon discovering the chaotic future that awaits him, Mxyzptlk declares that he would dedicate his life to learning and knowledge. However, those words led to a shift in time, creating an apocalyptic world everywhere but outside the building where the Halloween party is being held. This is because Mxyzptlk was not left to annoy Superman. In order to avoid this, Robin, Superboy, and Impulse realize that they need to instill Mxyzptlk with his trademark wacky sense of humor.

A Three Stooges film is uncovered and watched via an old projector. Mxyzptlk is entertained by the comedy in the movies. He tries out a Stooge-style poke in the eye on the projectionist Mick Gurk (an homage to the name "McGurk", the name used by Mxyztplk for a statue he animated in his first appearance), finding the slapstick humor to his liking. He promises that, when it is time, he will hassle Superman as he is supposed to, in honor of Superboy, Impulse, Robin, and even Mick Gurk.

Time is restored to as how it should be...mostly. Outside the civic center is an unexpected Mxyzptlk theme park, the only change to the world.

However, it appears that Mxyzptlk has forgotten this incident as the years have passed. When confronted by Superboy later on, the imp declares that he had no knowledge of his adventure with Young Justice. Whether or not this is true, or Mxyzptlk was merely playing a trick on the Boy of Steel, is never revealed.

In "Emperor Joker", a multi-issue story throughout the Superman titles, Mxyzptlk has his powers temporarily stolen by the Joker, who then remakes the Earth in his own image. The imp is unable to remember what to do to break the chain of events that daily culminates with Superman being dragged back to Arkham Asylum by Bizarro. Fortunately, Mxyzptlk is able to reveal the truth to Superman, who manages to find the power to break the cycle and defeat the Joker. As the Joker prepares to end existence, Superman realizes that, for all his power, the Joker still cannot erase Batman, as the Joker defines himself by his constant opposition to the Dark Knight, allowing Superman to shatter the Joker's control of reality. However, Mxyzptlk saves some of the Joker's creations and transfers them into the 'real' world, including Scorch, Gorgeous Gilly, the new Bizarro and "Ignition", a black-armored villain who first appeared in the "Emperor Joker" story, but was created by someone else (exactly who has never been revealed).[9]

It has also been implied that Mxyzptlk sees himself as serving an important purpose, in teaching Superman not to take everything too seriously.

In Adventures of Superman #617 (2003), Mxyzptlk is reinvented as fraternal twins with an intense hatred for Superman. Amongst other things, they claim responsibility for the creation of the present-day Persuader.[10] A year later, in Superman Secret Files and Origins 2004 (2004), he returns to his usual self following a fellow imp in the fifth dimension combining the twins with the classic Mxyzptlk, resulting in his normal form and personality.[11]

Mxyzptlk formed a significant part of Greg Rucka's "Ruin" storyline in Adventures of Superman. His appearance here is similar to his Golden Age look, with the addition of a single lock of hair, resembling Superman's S-shaped forelock. This version of Mxyzptlk is less abrasive than he had been previously, and is portrayed as basically on Superman's side. The metafictional aspects of the character were also played up, as he visits the DC Comics offices in the real world, presented as fumetti.

At the same time, Mxyzptlk appeared in Superman/Batman #23. During this time, his appearance is similar to the more typical "modern" version of the character. He is trying to prepare Batman and Superman for the upcoming Infinite Crisis (while chronologically taking place before Infinite Crisis, the issue itself came out afterwards). The incident features alternate universe versions of Superman, Batman, and Deathstroke the Terminator and implies much chaos that was not shown, such as the planet Mogo visiting Earth to reclaim an old land mass. At the end of this storyline, Mxyzptlk indicates he has erased the knowledge of Superman's identity from Lex Luthor's mind.

A weakened Mxyzptlk is seemingly killed by Ruin while protecting Superman, art by Karl Kerschl.

After the fallout of the events of Day of Vengeance (and, while not mentioned, the corruption of the fifth dimension as seen in JSA), the removal of magic from the Earth leaves Mxyzptlk nearly powerless, wandering the streets of Metropolis and unable to remember how to pronounce the inverse of his name to return him home. Superman attempts to help him, but the two are attacked by the villain Ruin. Ruin attempts to assassinate Superman with kryptonite-based weaponry, but Mxyzptlk pushes Superman out of the way, taking a kryptonite spear to the heart and vanishing. Right before he vanishes, he seems to whisper 'kltpzyxm'.

Action Comics Annual #10 states that Mister Mxyzptlk was last seen 190 days ago and that the pronunciation of his name is Mix-Yez-Pittle-Ick (as it was in the 1960s Superman CBS-TV cartoon show, mentioned previously).

Mister Mxyzptlk makes a one-page appearance in Countdown #31. On a walk in the fifth dimension with Gsptlsnz and his pet goldfish named Superman, he is grabbed by someone or something unknown, who then disappears with Mxy. It is later revealed in Countdown #23, Mxyzptlk was abducted by Superboy-Prime and imprisoned in the Source Wall.[12] Prime has been apparently torturing the imp into helping him bring back his "perfect Earth", i.e. Earth Prime. Mxyzptlk mentions that he has been coming to Earth for centuries, and has been referred to by many names (Loki, Coyote, and Anansi). He is later sent back to his home by Annataz Arataz, the Earth-3 counterpart of Zatanna, whom Prime had also captured. Arriving in the fifth dimension, he proclaims to Gsptlsnz that he has escaped an encounter with "the Beast" (implying that the fifth dimension is aware of Superboy-Prime, who is referred to as a being of pure evil). Knowing that Superboy-Prime will kill every living soul in the fifth dimension in order to get revenge on him, Mxyzptlk proclaims that their dimension must be sealed off from outsiders immediately and that he can never return to Earth.[13]

In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Mxyzptlk's history is revealed as a traveling wizard in the fifth dimension who entertained the King-Thing Brpxz of Zrfff. He did so by making 333 different three-dimensional worlds, and by challenging heroes in each world, with everyone being entertained by the one hero who could win the challenges, Superman. This led to Mxyzptlk becoming the king's favorite entertainer, and winning the love of the king's daughter, Gsptlnz. However, it also caused jealousy in the now-deposed original court magician, Vyndktvx. Vyndktvx eventually went mad and tried to kill Mxyzptlk, only to kill the king instead.[14] The instant of the murder of the king, committed with the Multispear - a hyper-weapon - reflected in the three-dimensional universe Superman inhabits as a lifelong struggle with the five-dimensional being. Mxyzptlk and his beloved wife descended to the three-dimensional universe to aid Superman in his struggle; their mortal forms perished in due time, still in the same instant in the time of their home world. There, even as he was defeated in the three-dimensional universe, Vndyktvx was arrested and imprisoned for the murder. Mxyzptlk became king and lived happily with his wife, the beautiful princess-now-queen, only to grieve as she died giving birth to their children. And so, he became the sad king that one day, the jester Mxyzptlk would come to entertain, and who would be slain by Vndyktvx in an eternal and apparently natural (for five-dimensional beings) cycle.[15]

After the New 52 Superman died and Pre-52 Superman took his place by the time of the DC Rebirth reboot, a mysterious Clark Kent appeared claiming to be the real one.[16] Despite everyone's hesitations and the previous event that outed Clark as Superman, the new Clark had the medical records to match, and when Superman questioned Clark with a telepathic probe, Clark presented a clear history of Clark Kent as a human being who was orphaned at three months old and subsequently adopted by the Kents.[17][18] Pre-52 Lois investigates the new Clark more after getting her job back at the Daily Planet.[19] Clark asks Lois out on a date which she accepts, but on the date, Lois finds that Clark rented the whole place out for the night and proposed to her, scaring her out of the date.[20] He follows Lois to her secret home and finds out about her marriage to Superman and their son, Jonathan. The next day, after spotting Clark, Superman and Lois's house and Jonathan suddenly disappear.[21] They track Clark down to his apartment, where he reveals himself to be Mister Mxyzptlk, who was absent from the New 52 universe because he was held captive by Mister Oz and used his powers to transform and brainwash himself into believing he was Clark Kent to avoid getting recaptured after escaping. His attacks on Superman are revenge for failing to notice he has been missing and he proceeds to make Lois forget about her own son.[22] As even Lois forgets that Clark and Superman were the same person, Superman agrees to play Mister Mxyzptlk's game to try and win back the 'right' to see his son again, but although Mister Mxyzptlk attempts to change the rules and ensure his victory, Jonathan is able to fight through his Mister Mxyzptlk-created prison with the aid of unspecified spirits that are revealed to be the New 52 versions of Superman and Lois, culminating in the creation of a new timeline where the essence of the Post-Flashpoint Lois and Clark are fused with their Pre-Flashpoint selves, so that the history of both worlds can co-exist.[23]

Mxyzptlk appears in Year Three. He poses as the Spectre and sides with Superman and explains his motives as wanting to bring "Order" to the world,[25] helping him against Batman's Insurgence and John Constantine's secret machinations. However, many start questioning the Spectre's sanity in following Superman, only to be quickly dealt with.[26][27] In the ensuing battle against Trigon, it is revealed Mxyzptlk was posing as the Spectre all along (his long exposure to the Spectre's darkness ends up corrupting him, giving him a darker and more insane look).[28] As he battles Trigon the reality around is altered, rendering all nearby superheroes useless. In a final attempt to stop the fierce magical battle, Doctor Fate, with help from Billy Batson, sends both Mxyzptlk, Trigon, and himself into "the Void", a place as close to death as they can be.[29]

Superman and Batman: World's Funnest (2000) features Mxyzptlk and Bat-Mite in a battle of magic that kills almost the entire DC Universe and other worlds, at which point they laugh and agree to meet again "next Tuesday", thus revealing that the destruction is both temporary and also a regular source of entertainment for the magical pair.

In The Brave and the Bold #11, Superman is confronted with Ultraman, his counterpart from the Antimatter Universe which most famously housed Qward; however, they are interrupted mid-battle by Mixyezpitellik, Mxyzptlk's own Antimatter counterpart. This counterpart does not reside in Qward, but is another inhabitant of the fifth dimension; he loathes being compared to Mxyzptlk, who he refers to as a 'madcap imp'. Just as Ultraman is in every way the opposite of Superman - uncontrolled, violent, and petulant - so is Mixyezpitellik from Mxyzptlk. He appears dressed in a neat suit and carries an umbrella and wears a large fedora rather than the clownish bowler, though it is still colored purple like that of his counterpart, and refers to himself as 'a vowelled Knight of Order', suggesting that the use of vowels in the fifth dimension denotes rank. Notably, Mixyezpitellik specifically states his powers are magic-based and thus limited to some degree, as indicated by him being changed by the very nature of the matter-based reality to become more imp-like to fit into its reality structure. Mixyezpitellik's relationship with Ultraman also mirrors that between Mxyzptlk and Superman; while to Superman, Mxyzptlk is merely a mischievous annoyance who rarely makes a great impact upon him, Ultraman finds himself terrified by Mixyezpitellik's power and is thus made to act as his agent.

Mxyzptlk is the main villain in the miniseries. Here, he is disguised as the principal of Stanhope Boarding School, which Supergirl, Lena Luthor, and Belinda Zee attend. At the end of issue #5, Mxyzptlk and his henchmen (fellow teachers) reveal their true forms while laughing at the chaos they have spawned.

In the last issue of the series, it is revealed that Mxyzptlk was behind Supergirl's rocket landing in Metropolis, and almost all the catastrophes in the series, hoping to use her emotions to power a machine that would give him an unlimited amount of energy. It is even suggested that he might have been behind the destruction of Krypton in the first place, just to manipulate events to the current point. After being beaten by an omnipotent Supergirl, who is revealed to be the hand Krona saw, he retreats back to the fifth dimension...only to be banished to a two dimensional prison by his own henchmen, as punishment for "breaking the rules of the game".

Mister Mxyzptlk appears in Superman and Batman Generations. In 1959 he was pulled from the fifth dimension along with Bat-Mite by the Epsilon Eridanites to help find a hero that would help them defeat the Bortan Empire. Two of their representatives have found two worthy candidates in the form of Superman and Batman, and they wanted Mxyzptlk to test out Bat-Mite's hero Batman to find out his worthiness, while Bat-Mite tested out Mxyzptlk's hero Superman. Eventually Superman brought the whole contest over to Gotham City, having Bat-Mite's monster fight with Mxyzptlk's. Mxyzptlk decided at that point to create one giant tentacled monster to deal with both heroes. However, both Superman and Batman decided to make themselves look like they were totally defeated and destroyed by the monster so that the Epsilon Eridanites would end up choosing both Mxyzptlk and Bat-Mite as their heroes to take care of the Bortan threat, forever removing them from bothering either Superman or Batman ever again.[30]

• Mxyzptlk first appeared in animated form in the Filmation series The New Adventures of Superman episode "Imp-Practical Joker," voiced by Gilbert Mack. In this appearance, Filmation used the official DC Comics pronunciation of his name. Mister Mxyzptlk causes mischief at a carnival outside of Metropolis until Superman arrives. Superman tries to get Mxyzptlk to say his name backwards at different attempts (one of them in his Clark Kent guise which, of course, did not work) and finally manages to trick Mxyzptlk into saying his name backwards by messing up the pronunciation of his name. Superman even taunts Mxyzptlk by pronouncing his name "Mixed Pickle", which brings an antagonized response from him each time.
• Mister Mxyzptlk appeared in the Super Friends animated series, voiced by Frank Welker. In that series, Mxyzptlk's name is pronounced as Miks-ill-plik (backwards, Kilp-ill-skim) and he takes to tormenting all the members of the team, even when Superman is absent.
  • In the Challenge of the Super Friends episode "The Rise and Fall of the Super Friends", Mxyzptlk forces the Super Friends to act out the roles in a movie he is directing. Superman secretly rewrites the script to include "Kltpzyxm" and tricks him into reading it to banish him.
  • In The World's Greatest Super Friends episode "The Planet of Oz", Mxyzptlk transports Superman, Wonder Woman, and Aquaman to the Land of Oz and tells them they must find the Wizard to get home. Along the way, Mxyzptlk takes the guise of the Wicked Witch of the Worst Kind and turns Aquaman into the Scarecrow, Superman into the Tin Woodman, and Wonder Woman into the Cowardly Lion, drastically weakening their powers. When the heroes finally find the Wizard and ask to be sent home, the Wizard reveals himself to be Mxyzptlk in yet another disguise and explains that during their journey, the heroes unwittingly collected ingredients for a potion that will render him immune to being banished to the fifth dimension. However, the heroes had figured out his scheme earlier and swapped out one of the ingredients, so after goading him into proving that the potion actually worked, he says his name backwards and banishes himself.
  • In the 1980s Super Friends episode "Mxyzptlk Strikes Again", claiming he is writing a novel, he uses a magic typewriter that makes whatever is written come true to torment the Super Friends and make them fight each other. Green Lantern uses his ring to reprogram the typewriter to only write "Kltpzyxm" and the imp unwittingly reads it and is banished. In the episode "Mxyzptlk's Flick", he traps Batman, Robin, the Wonder Twins, and Gleek inside a movie about cavemen and dinosaurs and torments them with a magic camera that can rewind and edit their actions into something embarrassing. After he is goaded into saying his own name, Gleek sneaks up on him and presses the Rewind button on the camera to force him to say it backwards and banish him. In the episode "Mxyzptlk's Revenge", he transports Superman and Batman to the fifth dimension to torment them, pointing out saying his name backwards is meaningless since he is already in the fifth dimension. Since the rules of reality are different in the fifth dimension, Superman eventually tricks him into saying his name forwards, transporting Superman and Batman back to Earth.
  • In the Super Friends: The Legendary Super Powers Show episode "Mr. Mxyzptlk and Magic Lamp", a small time crook named Benny steals a lamp from a museum. Mxyztplk decides to pretend to be the genie of the lamp and uses his powers to help Benny commit grand crimes and escape the Super Friends. When they decide to hack into bank accounts to get their passwords, Batman sends a signal that makes one of the passwords his name backwards, and he reads it and is banished. In the episode "Uncle Mxyzptlk", Superman is turned into a bratty toddler by a sample of red kryptonite and Mxyzptlk quickly takes him under his wing and encourages him to use his powers for mischief. Samurai rearranges the letters in a sign that spelled his name to spell it backwards and tricks him into reading it to banish him.
  • In The Super Powers Team: Galactic Guardians episode "The Bizarro Super Powers Team", Bizarro creates Bizarro duplicates of Wonder Woman, Firestorm, and Cyborg to serve as defenders for Bizarro World. Mxyzptlk takes the Bizarros under his wing under the guise of training them to be heroes, but instead teaches them to wreak havoc on Earth. Wonder Woman steals the Bizarro duplicator ray and uses it on Mxyzptlk so Mister Kltpzyxm, a Bizarro Mxyzptlk, is created, who promptly speeds off to turn the Bizarro World into a beautiful planet like Earth, much to Bizarro's horror. As the Bizarros return to Bizarro World to stop Mister Kltpzyxm, Mxyzptlk tries to tell them to ignore his counterpart and remain on Earth, accidentally saying his counterpart's name and banishing himself.
• In the 1990s cartoon Batman: The Animated Series, Mister Mxyzptlk briefly appeared as a silent, animatronic toy created by Dr. Karl Rossum in the third-season episode "Deep Freeze". His design is identical to the Bronze Age version, and he was seen riding on a flying carpet. Bat-Mite, Streaky the Supercat, and Krypto the Superdog can also be seen.

Mxyzptlk, as seen in Superman: The Animated Series

• In the 1990s animated series, Superman: The Animated Series, Mister Mxyzptlk was voiced by comedian Gilbert Gottfried. This version's design was closer to the Golden Age version. In his main introduction (after having pulled a few pranks on Superman without identifying himself), Clark sees him as a comic strip character in a newspaper Jimmy had given him and read his name using the pronunciation "Mix-ul-plict" (a nod to the Super Friends cartoon). Myx then demonstrated the correct pronunciation, "mix-yes-spit-lick", by turning into a mixer, an album cover of the band Yes, back into himself while spitting at Superman, and then a dog that licks Superman. In a nod to Lois & Clark, Mxyzptlk at one point tells Superman that he is responsible for inspiring Earth legends about imps, genies, and leprechauns. In this incarnation, he appears as a comical annoyance; once he explains to Superman his weakness, he is repeatedly tricked into saying his name backwards before he can put up much of a fight. In one visit, he interrupts Superman's heat-vision shave, but Superman tricks him by deliberately saying his name as Mister "Kltpzyxm". Another one sees him armed with a powered exoskeleton to kill Superman before he could be tricked, and is forced back offscreen in under three seconds. He is forced to leave Superman alone for good after being tricked into displaying "Kltpzyxm" twice in a row, but vows to find a loophole and return. He returns again in "Little Big Head Man" to trick Bizarro into attacking the Man of Steel after teleporting him from the Bizarro World. He gets in trouble with the fifth dimension's tribunal (voiced by Corey Burton who was not credited for the role) who punish him for his mischief by stripping him of his powers and sending him to the third dimension to do good deeds in three months in which he will be able to return if they are complete. Even saying his name backwards does not work. Following Bizarro's defeat, Superman learns what the tribunal sentenced Mister Mxyzptlk to do during the three months on Earth. When Mister Mxyzptlk offered to press his cape, Superman came up with a better deed for him to do. On the Bizarro World, Mister Mxyzptlk become Bizarro's assistant on his home planet by portraying each of the citizens. After snapping at Bizzaro for nearly hurting him, Mister Mxyzptlk gets chased up a tree by Krypto. As he rants about his torment, Superman is shown watching on the monitor as he works "Life am good."
  • According to the commentary for "Mxyzpixilated", there were plans for him to star in a Justice League episode, but neither writer Paul Dini (a huge fan of the character, who wrote "Mxyzpixilated") nor series creator Bruce Timm could figure out a story that would be suitable. He did make a "cameo" as a cardboard cutout used in a training exercise in the episode "Secret Society - Part 1", however. This incarnation resembles the original Mister Mxyzptlk, rather than the two more modern versions.
• Mister Mxyzptlk is featured in Batman: The Brave and the Bold, voiced by Kevin Michael Richardson. He is mentioned by Batman in "Legends of the Dark Mite!" when he learns that Bat-Mite is from the fifth dimension and that he tells Bat-Mite that a friend in Metropolis (Superman) had warned him about fifth dimensional beings. In "Battle of the Superheroes!", he is causing mischief in Metropolis until Superman tricks him into saying his name backwards with a knock-knock joke. In this series, his name is pronounced "Mix-ee-yez-pit-lik".
• Mister Mxyzptlk appears in Justice League Action episode "Mxy's Mix-Up", voiced again by Gilbert Gottfried. When he accidentally says his name backwards, it is pronounced "Kl-tp-zyx-m", while from the Superman series it is "Kl-tp-zy-xm." He crashes Superman, Batman, and Stargirl's battle with Gorilla Grodd and his army of gorillas where he mixes up the minds of Superman, Batman, and Stargirl to the point it causes them some difficulty fighting Gorilla Grodd. When the Justice League's bravo team (consisting of Cyborg, the Flash, the Martian Manhunter, Shazam, and Zatanna) arrive with Firestorm, Mister Mxyzptlk mixes up their minds too, though Mister Mxyzptlk did not count on him hearing Martin Stein's voice due to Firestorm having a dual mind. Martin Stein manages to trick Mister Mxyzptlk into saying his name backwards, which sends Mister Mxyzptlk back to the fifth dimension and undoes his magic on the Justice League enough for them to defeat Gorilla Grodd and his army.

• Michael J. Pollard portrayed Mxyzptlk in the 1988-1992 live-action syndicated series Superboy in two episodes from seasons 1 and 2.

• Howie Mandel portrayed Mxyzptlk in the 1990s live-action series Lois & Clark: The New Adventures of Superman episode "Twas the Night Before Mxymas".[31] Mandel pronounced the name ""Mix-yez-pit-leck". Mxyzptlk is said to have a long history of earlier visits to Earth, inspiring the myths of imps, genies and leprechauns, as well as real historic events, such as the Fall of Rome. Like the comics version, he is a native of the fifth dimension and could only be sent back by saying his name backwards, but he is more malevolent: his desire was to force Superman to leave Earth so he could take it over. He trapped Christmas Eve in a time loop where humanity became progressively more despondent and violent in each go-round because of the lack of hope for the future, edging toward World War III. Superman, the only being who could perceive the timeline's repetitions, restored the people's hope by proactively averting the impending tragedies before tricking Mxy into accepting a Christmas present from "Kltpzyxm", sending him back to the fifth dimension.

Trent Ford (right) as Mikhail Mxyzptlk with Chloe Sullivan (Allison Mack) in the Smallville Season 4 episode "Jinx"

• In Smallville, a character named Mikhail Mxyzptlk (pronounced Mix-ill-pit-ill-lick) appeared in the Season 4 episode "Jinx" portrayed by Trent Ford.[32] Mikhail is a young foreign exchange student sponsored by LuthorCorp who started an underground gambling ring at Smallville High School. In this series, Mikhail is from a line of people said to control luck (the "Kltpzyxm" family, until they changed their surname to Mxyzptlk and fled the Balkans). His power is to control a target's actions by verbal commands on an ultrasonic frequency. For example, when he mutters "trip" from all the way in the stands, Clark Kent trips in the middle of a football play. He was defeated and his powers apparently lost when Clark and Chloe Sullivan broadcast a sound frequency that disrupted his ability to use his powers. However, Lex Luthor later recruits him as part of the 33.1 Project, promising Mikhail the restoration of his powers. The character did not reappear on the show. In the season 11 comic book series, Lex encounters Mikhail's uncle, who is the Prime Minister of Russia. Mikhail's uncle reveals that Mikhail was eventually sent home, without having regained his powers.[33]

Thomas Lennon played Mxyzptlk in Supergirl's milestone 100th episode

• Mister Mxyzptlk appears in Supergirl portrayed by Peter Gadiot in season two[34] and by Thomas Lennon in season five.[35] He is an imp from the fifth dimension who shows up at the end of the season two episode "Luthors", before making his full debut in "Mr. & Mrs. Mxyzptlk". Just as Kara is telling Mon-El of her feelings for him, Mxyzptlk appears before her, having watched her from the fifth dimension and fallen in love with her. Mon-El angrily demands that he say or spell his name backwards, as that would banish him back to the fifth dimension. Despite his reality-warping powers, Mxyzptlk cannot directly make Kara marry him or stop her from killing herself, so he interferes with her life in increasingly dangerous ways as part of his vain efforts to win her over. Pretending to accept his marriage proposal, Supergirl lures him to the Fortress of Solitude and triggers an imminent nuclear meltdown, threatening her life until Mxyzptlk types in the kill code, which translates from Kryptonian to "KLTPZYXM", sending him away. In this episode, he declares that his name is pronounced as it is spelled. Mister Mxyzptlk reappears at the end of the episode "Back from the Future Pt. 2", where he appears at Kara's loft.[36] In the episode "It's a Super Life," Mister Mxyzptlk explains that Kara and Alex do not recognize him because he had assumed a different form last time in his attempt to win Kara over. Now ordered by some unspecified higher powers to atone for his past transgressions toward Kara, Mxyzptlk sends Alex Danvers and the Martian Manhunter to a paintball course and gives Kara a tape recorder with him saying his name backwards that she can use to get out of a problem. Mxyzptlk then shows Kara possible realities where Supergirl revealed her identity to Lena at different points, but Kara is unable to find a scenario where Lena will not react badly to the news, reactions ranging from Lena leaving National City or basically abandoning Kara in situations where Lena's assistance would have been crucial to Lena and Mon-El dying at the hands of Reign. Even when Kara tells Lena the truth from the beginning, it results in the death of Kara's loved ones when Agent Liberty and Otis kidnap Lena and Thomas Coville to lure Kara into a trap. When it came to a possible reality where Supergirl and Lena never met, it had Lena taking over the remaining half of National City and harnessing the energies of the fifth dimension to power her Hope-Bots, which explained why Mxyzptlk was unable to use his powers. It was also mentioned that the Hat was an old drinking buddy of his who took his hat. Once Mxyzptlk was able to draw on the powers of the fifth dimension, he undid the reality.

• Mxyzptlk was one of the villains considered for Superman III, as written in an outline by Ilya Salkind, but the idea was scrapped. The Mister Mxyzptlk portrayed in the outline varies from his good-humored comic counterpart, as he uses his abilities to seriously harm. Dudley Moore was the top choice to play the role.[37]

• Mister Mxyzptlk appears in Scribblenauts Unmasked: A DC Comics Adventure. He gives the players conditions in the game that, if followed, will reward the player with double the reputation points. Examples of those conditions are only using words that start with a specific letter or turning everything in the environment into zombies.
