Mister Mxyzptlk


Mister Mxyzptlk, sometimes called Mxy, is a fictional impish character who appears in DC Comics' Superman comic books, sometimes as a supervillain and other times as an antihero.
Mr. Mxyzptlk was created to appear in Superman #30, in the story "The Mysterious Mr. Mxyztplk", by writer Jerry Siegel and artist Ira Yarborough. But due to publishing lag time, the character saw print first in the Superman daily comic strip by writer Whitney Ellsworth and artist Wayne Boring.
He is usually presented as a trickster, in the classical mythological sense, in that he possesses reality warping powers with which he enjoys tormenting Superman in a cartoonish way. In most of his appearances in DC Comics, he can be stopped only by tricking him into saying or spelling his own name backwards, which will return him to his home in the 5th dimension and keep him there for a minimum of ninety days. However, this specific limitation of the character has been eliminated since the Crisis on Infinite Earths reboot, upon which the character leaves only when he willingly agrees to do so after meeting some conditions he sets, such as having Superman succeed in getting Mxyzptlk to paint his own face blue.
The character appeared in live-action portrayed by Howie Mandel in the 1993 television series . The character, renamed Mikhail Mxyzptlk, also appeared in the television series Smallville played by Trent Ford. Mxyzptlk appears in the television series Supergirl played by Peter Gadiot in the second season and by Thomas Lennon in the fifth season.

Fictional character biography

Golden Age

Mister Mxyztplk was introduced in the Golden Age as an imp from the "fifth dimension". 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's 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. His only weaknesses are that he cannot stand being ridiculed and if he says or spells his name backwards, Klptzyxm, he is involuntarily sent back to his home dimension for a minimum of ninety 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.

Silver Age

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, the spelling of Mxyztplk's name changed to "Mxyzptlk".
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 5th dimension, 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" repeatedly, but when he finally succeeds, it does not work and Superman remains in the 5th dimension. Mxyzptlk ultimately loses the election, and, his mission accomplished, Superman banishes himself back to Earth by whispering "Le-Lak".

Multiverse

After the establishment of DC Comics' multiverse in the 1960s, it was later explained that the purple-suited Mxyztplk 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 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 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 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.

''Whatever Happened to the Man of Tomorrow?''

offered a radically different interpretation of the character in the 1986 , a possible end of the adventures of the Earth-One Superman. Mister Mxyzptlk 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. 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 5th Dimension, 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.
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 5th 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.

Modern Mxyzptlk

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.
Many of Mxyzptlk's later stories have a post-modern 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 volume 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.
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 & games. Mxyzptlk retains the services of a version of Bizarro who calls him Greg, and pads the story out by writing & drawing 27 off-beat stories using the DC super-heroes, taking 160 pages. Bizarro is in 2 of them. Also of note is the depiction of Bahdnesian thunderbolts and Zook's species as native to the 5th 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.

Secret Origin

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. 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, 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 merely playing a trick on the Boy of Steel, is never revealed.

Improper Use of Power

In "Emperor Joker", a multipart story throughout the Superman titles, Mxyzptlk has his powers temporarily stolen by the Joker, who then remakes the Earth. 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.
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, 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. A year later, in Superman Secret Files and Origins 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.
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. The incident features alternate universe versions of Superman, Batman, and Deathstroke 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.
After the fallout of the events of Day of Vengeance, 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'.

One Year Later

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.

Countdown

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. 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. 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". 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.

The New 52

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 5th dimension who entertained the King-Thing Brpxz of Zrfff. He did so by making 333 different 3-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. 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 cycle.

DC Rebirth

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. 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. Pre-52 Lois investigates the new Clark more after getting her job back at the Daily Planet. 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. 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. 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. 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.

Powers and abilities

Mister Mxyzptlk possesses the ability to warp reality, which has been described alternatively as the product of fifth-dimensional magic or advanced technology that appears to be magical to third-dimensional beings. Attendant with his abilities is the fact that Mxyzptlk himself is not limited by physical laws: he needs no sustenance such as air or water, can exist in any environment, has the ability to teleport anywhere, and is not susceptible to physical harm. His only apparent vulnerability is that whenever he speaks his name backwards, he is shunted back to the fifth dimension, and all effects of his magic vanish, making everything as it was before he appeared.
However, such a banishment is just a temporary deterrent: after ninety days, Mxyzptlk can again visit the third dimension at will. His reality warping powers exist in the fifth dimension but he exerts less control compared to the third dimension, due to the presence of other imps with the same powers.
Though easily the most powerful of Superman's recurring enemies, the scope of Mxyzptlk's true potential is limited by his personality: his gullible nature makes it easy for Superman or other individuals to trick him into saying his name backwards, and he is overall a fun-loving prankster who prefers to use his power for childish mischief and light-hearted harassment rather than malicious destruction or torment. Thus, he is more of an annoyance to the Man of Steel than a true threat.

Other versions

Injustice: Gods Among Us

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, 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. In the ensuing battle against Trigon, it is revealed Mxyzptlk was posing as the Spectre all along. 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.

Superman and Batman: World's Funnest

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.

Antimatter Universe

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 5th 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 as 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.

Supergirl: Cosmic Adventures in the Eighth Grade

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 the fifth issue Mxyzptlk and his henchmen 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".

Superman and Batman: Generations

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.

Cultural references

Due to the phonetic difficulties in pronouncing a name spelled without vowels such as Mxyzptlk, it has been pronounced in various ways by various sources over the past four decades. On the 1967 Filmation CBS Superman animated series, it was pronounced as mix-yez-PITTLE-ik; sources indicate that was the official DC Comics version of the time, furnished to the show's writers through DC Comics editor/writer E. Nelson Bridwell. During the 1980s, on the Super Friends cartoon, produced by Hanna-Barbera, it was approximated as Mix-Ill-Plick. Miks-yez-pit-lik is actually a general translation and other variations have included mix-yez-PIT-lek, mix-yez-PIT-ul-ick, and mix-yez-pittle-ik. To further complicate matters, Mxyzptlk says himself in the 1990s of Superman, that his name is pronounced the same as saying the words "mix, yes, spit, lick", even transforming himself into the appropriate illustrations for the words. Clark had pronounced his name as Mix-Ill-Plick before Mxyzptlk popped out of the comic and proceeded to correct him. In his appearance in the Superman Returns video game, Mxyzptlk proudly refers to himself as "the one and only Mr. Mix-yiz-SPIT-Lik!, straight from the fifth dimension!" Miks-il-piti-lik was used on Smallville, all while the original spelling of his name was pronounced mix-pit-tulk. This has created great confusion and even debate as to how his name is actually to be spoken.
In Action Comics Annual #10, "Superman's Top 10 Most Wanted" describes Mister Mxyzptlk and provides the pronunciation as mix-yez-pittle-ik, exactly like the 1967 animated series. So, phonetically, the pronunciation backwards would be "kell-tipp-ZEY-skim." Confusingly, the 1967 animated series used the backwards pronunciation "kulp-ti-Mix-im." It's fair to say that producers were free to interpret the name any way they wanted, just as they routinely changed other elements of comic lore to suit their various series.
