Thanos

Thanos is a supervillain appearing in American comic books published by Marvel Comics. Created by writer-artist Jim Starlin, the character first appeared in The Invincible Iron Man #55 (cover date February 1973). An Eternal–Deviant warlord from the moon Titan, Thanos is regarded as one of the most powerful beings in the Marvel Universe. He has clashed with many heroes including the Avengers, the Guardians of the Galaxy, the Fantastic Four, the Eternals, and the X-Men.

In creating Thanos, Starlin drew inspiration from Jack Kirby's New Gods series for DC Comics, particularly the character of Darkseid. Thanos is usually portrayed as a villain, although many stories depict him as believing his actions to be justified. Perhaps the character's best-known storyline is The Infinity Gauntlet (1991), the culmination of several story arcs that see him gather the six Infinity Gems and use them to kill half of the universe's population, including many of its heroes, to woo Mistress Death, the living embodiment of death in the Marvel Universe. Although these events were later undone, the storyline has remained one of the most popular published by Marvel.

Debuting in the Bronze Age of comic books, the character has appeared in almost five decades of Marvel publications, as well as many media adaptations, including animated television series and video games.

In the Marvel Cinematic Universe, the character was first played by Damion Poitier in the film The Avengers (2012) and then by Josh Brolin in Guardians of the Galaxy (2014), Avengers: Age of Ultron (2015), Avengers: Infinity War (2018), Avengers: Endgame (2019), and the first season of the animated series What If...? (2021).

Creation
Writer-artist Jim Starlin conceived of Thanos of Titan during college psychology classes. As Starlin described:

"I went to college between doing U.S. military service and getting work in comics, and there was a psych class and I came up with Thanos, (inspired by Sigmund Freud's concept of human Death drive, or Thanatos), but I'm not sure how he fit into it, just anger management probably. So I came up to Marvel, and editor Roy Thomas asked if I wanted to do an issue of Iron Man. I felt that this may be my only chance ever to do a character, not having the confidence that my career was going to last anything longer than a few weeks. So they got jammed into it. Thanos was a much thinner character and Roy suggested beefing him up, so he's beefed up quite a bit from his original sketches ... and later on I liked beefing him up so much that he continued to grow in size."

Starlin has admitted the character's look was influenced by Jack Kirby's Darkseid:

"Kirby had done the New Gods, which I thought was terrific. He was over at DC at the time. I came up with some things that were inspired by that. You'd think that Thanos was inspired by Darkseid, but that was not the case when I showed up. In my first Thanos drawings, if he looked like anybody, it was Metron. I had all these different gods and things I wanted to do, which became Thanos and the Titans. Roy took one look at the guy in the Metron-like chair and said: 'Beef him up! If you're going to steal one of the New Gods, at least rip off Darkseid, the really good one!'"

The character's origin was expanded in the five-issue Thanos Rising miniseries by Jason Aaron and Simone Bianchi which was published monthly beginning in April 2013. Later that same year, Thanos played a central role in the Infinity miniseries written by Jonathan Hickman and drawn by Jim Cheung, Jerome Opeña, and Dustin Weaver.

In May 2014, Jim Starlin and Ron Lim worked together on the one-shot Thanos Annual, which is a prelude to a new trilogy of original graphic novels. The first, Thanos: The Infinity Revelation, was released the following August. Beginning in February 2015, Starlin also penned a four-issue miniseries titled Thanos vs. Hulk, which was set prior to the graphic novels. The second installment in the trilogy, Thanos: The Infinity Relativity, was released in June, 2015. The third graphic novel, Thanos: The Infinity Finale, as well as the connected mini-series The Infinity Entity were published in 2016.

In 2017, as part of Marvel NOW!, Thanos received his own solo title written by Jeff Lemire and drawn by Mike Deodato. After 11 issues, Donny Cates and Geoff Shaw took over as the creative team. This storyline crossed over with Donny Cates' Cosmic Ghost Rider storyline.

In 2021, Thanos was later reintroduced as a primary antagonist in the comic series Eternals vol. 5, #1-12, by the writer Kieron Gillen and artist Esad Ribić, and plays a prominent role in exploring Eternals mythos and retcons.

Fictional character biography
Thanos was born on Saturn's moon Titan as the son of Eternals A'lars and Sui-San, the grandson of Kronos, the nephew of Zuras, and the grandnephew of Oceanus and Uranos. His brother is Eros of Titan. Thanos carries the Deviants gene, and as such, shares the physical appearance of the Eternals' cousin race. Shocked by his appearance and the belief that he would destroy all life in the universe, Sui-San went insane and attempted to kill him, but she was stopped by A'lars. During his school years, Thanos was a pacifist and would only play with his brother Eros and pets. By adolescence, Thanos had become fascinated with nihilism and entropy, worshipping and eventually falling in love with the physical embodiment of Mistress Death.

At some point in his youth, a younger Thanos was sent to Earth by Mephisto where he fought the prehistoric Avengers where he was repelled.

As an adult, Thanos augmented his physical strength and powers through his superior scientific knowledge using a combination of mysticism and cybernetic enhancements. He also attempted to create a new life for himself by siring many children as well as becoming a pirate. He finds no fulfillment in either until he is visited again by Mistress Death, for whom he murders his offspring and his pirate captain.

Wishing to impress Mistress Death, Thanos gathers an army of villainous aliens and begins a nuclear bombardment of Titan that kills millions of his race. Seeking universal power in the form of the Cosmic Cube, Thanos travels to Earth. Prior to landing, his vessel destroys a nearby car as a family witnesses his arrival. Unbeknownst to Thanos, two of the family members in the vehicle survive: the father's spirit is preserved by the Titanian cosmic entity Kronos and is given a new form as Drax the Destroyer while the daughter is found by Thanos's father, Mentor, and is raised to become the heroine Moondragon. Thanos eventually locates the Cube, and also attracts the attention of Mistress Death. Willing the Cube to make him omnipotent, Thanos then discards the Cube. He imprisons Kronos and taunts Kree hero Captain Marvel, who, with the aid of superhero team the Avengers and ISAAC (a super-computer based on Titan), is eventually able to defeat Thanos by destroying the Cube.

Thanos later comes to the aid of Adam Warlock in a war against the Magus and his religious empire. During the process, he ends up adopting Gamora to use her as his assassin and kill Adam Warlock before becoming Magus. During this alliance Thanos cultivates a plan to reunite with Mistress Death, and secretly siphons off the energies of Warlock's Soul Gem, combining these with the power of the other Infinity Gems to create a weapon capable of destroying a star. Warlock summons the Avengers and Captain Marvel to stop Thanos, although the plan is foiled when Thanos kills Warlock. The Titan regroups and captures the heroes, who are freed by Spider-Man and the Thing. Thanos is finally stopped by Warlock, whose spirit emerges from the Soul Gem and turns the Titan to stone. Thanos's spirit eventually reappears to accompany a dying Captain Marvel's soul into the realm of Death.

During the "Infinity Saga" storyline, Thanos is eventually resurrected and collects the Infinity Gems once again. He uses the gems to create the Infinity Gauntlet, making himself omnipotent, and erases half the living things in the universe to prove his love to Death. This act and several other acts are soon undone by Nebula and Adam Warlock. Warlock reveals that Thanos has always allowed himself to be defeated because the Titan secretly knows he is not worthy of ultimate power. Thanos joins Warlock as part of the Infinity Watch and helps him to defeat first his evil and then good personas, and cure Thor of "warrior Madness".

Thanos later recruits a team of Earth-bound super-villains and puts them under the field leadership of Geatar in a mission to capture an ancient robot containing the obscure knowledge of a universal library and extract its data. Thanos uses information from the robot to plot against and battle Tyrant, the first creation of Galactus turned destroyer. When trapped in an alternate dimension, Thanos employs the aid of the brother of Ka-Zar, Parnival Plunder and later the Hulk to escape, although both attempts are unsuccessful. Thanos is eventually freed and comes into conflict with Thor, aligning himself with Mangog in a scheme to obtain powerful mystical and cosmic talismans which will allow him to destroy all life in the universe, and during their battles Thanos decimates the planet Rigel-3.

Thanos then uses the heroes Thor and Genis-Vell (Captain Marvel's son) against the death god Walker, who attempts to woo Mistress Death and then destroy the entity after being rejected. Thanos then devises a plan to become the All-Father of a new pantheon of gods created by himself. Thanos, however, finds himself opposed by the Avengers' former member Mantis and her son Quoi, who apparently is destined to be the Celestial Messiah. Thanos abandons this plan after having to unite with Mistress Death to destroy the "Rot", a cosmic aberration in deep space caused by Thanos's incessant love for Death. Thanos also once conducted extensive research on genetics, studying many of the universe's heroes and villains before cloning them, and gene-spliced his own DNA into the subjects. Although he later abandons the project, five clones survive, being versions of Professor X, Iron Man, Gladiator, Doctor Strange, and Galactus respectively. A sixth and unnamed version of Thanos also appears, and it is revealed the incarnations of Thanos encountered in the past by Thor and Ka-Zar were actually clones. The true Thanos – with the aid of Adam Warlock, Gamora, Pip the Troll, Spider-Man, Captain Marvel, and Dr. Strange – destroys the remaining clones.

When the ancient Egyptian pharaoh Akhenaten uses a source of cosmic power, the Heart of the Universe, to seize power in present-day Earth (killing most of Earth's heroes in the process), Thanos uses a time-travel stratagem to defeat him. Thanos then uses the Heart of the Universe to reverse Akhenaten's actions and was also compelled to correct a flaw in the universe, for which Mistress Death kisses him, and speaks to him for the first time. Changed by the experience, Thanos advises confidant Adam Warlock he will no longer seek universal conquest.

Thanos decides to atone for the destruction of Rigel-3, and agrees to aid a colony of Rigellians in evacuating their planet before Galactus can consume it. During the course of this mission Thanos learns Galactus is collecting the Infinity Gems in an effort to end his unyielding hunger. Thanos later learns Galactus is being manipulated into releasing a multiversal threat called Hunger, which feeds on entire universes. Despite opposition from Thanos, Galactus unwittingly frees the entity, and when its intentions are revealed, the pair team up and attempt to destroy it.

En route to the Kyln, an intergalactic prison, Thanos meets Death for the first time since re-building existence with the Heart of the Universe. Death claims to be worth wooing, but says Thanos must offer something other than death. At the Kyln Thanos encounters Peter Quill, who has retired himself from the role of Star-Lord, and the Strontian warrior Gladiator of the Shi'ar Empire, who are both prisoners, as well as the Beyonder, who has been rendered amnesiac by its choice to assume a humanoid female form. Thanos battles the Beyonder, causing its mind to shut down and leaving its power trapped within a comatose physical form. Thanos then instructs the Kyln officers to keep the Beyonder on life support indefinitely to prevent the entity from being reborn. The destruction frees Thanos and his fellow inmates, and he finds himself accompanied by the chaos-mite Skreet in his plans to leave the remains of the prison. He discovers, however, that the destruction wrought by the battle with the Beyonder has freed the last prisoner brought in by Peter Quill before he gave up the title of Star-Lord: the Fallen One, revealed to be the true first Herald of Galactus, who had been held in a container deep in the Kyln. Thanos defeats the former Herald and places him under complete mental control. He later appears in Wisconsin attempting to charge a weapon called the Pyramatrix with the life force of everyone on Earth until he is defeated by Squirrel Girl. After the battle, Uatu the Watcher appears and confirms to Squirrel Girl that she defeated the real Thanos, not a clone or copy.

During the Annihilation War, Thanos allies himself with the genocidal villain Annihilus. When the Annihilation Wave destroys the Kyln, Thanos sends the Fallen to check on the status of the Beyonder, whose mortal form he finds has perished. Before the Fallen can report back to Thanos it encounters Tenebrous and Aegis: two of Galactus's ancient foes. Thanos convinces Tenebrous and Aegis to join the Annihilation Wave to get revenge on Galactus, and they subsequently defeat the World Devourer and the Silver Surfer. Annihilus desires the secret of the Power Cosmic and asks Thanos to study Galactus. Once Thanos learns Annihilus's true goal is to use the Power Cosmic to destroy all life and remain the sole survivor, he decides to free Galactus. Drax the Destroyer kills Thanos before he can do so but discovers that Thanos had placed a failsafe device to allow Silver Surfer to free Galactus in the event that Annihilus betrayed him. During a climactic battle with Annihilus, Nova is near death and sees Thanos standing with Mistress Death.

During "The Thanos Imperative" storyline, a cocoon protected by the Universal Church of Truth is revealed to be hiding Thanos, who has been chosen by Oblivion to be the new Avatar of Death. Resurrected before his mind could be fully formed, Thanos goes on a mindless rampage before being captured by the Guardians of the Galaxy. Thanos pretends to aid the Guardians against the invading Cancerverse, and after discovering its origin kills an alternate version of Mar-Vell, the self-proclaimed Avatar of Life. This causes the collapse of the Cancerverse, and Nova sacrifices himself in an attempt to contain Thanos inside the imploding reality. Thanos escapes and returns to Earth seeking an artificial cosmic cube. He forms an incarnation of the criminal group Zodiac to retrieve it, but he is defeated by the Avengers and the Guardians of the Galaxy and remanded to the custody of the Elders of the Universe.

During the "Infinity" storyline, Thanos soon invades Earth again after being informed that most of the Avengers have temporarily left the planet. He launches an assault on Attilan, which he offers to spare in exchange for the deaths of all Inhumans between the ages of 16 and 22. Black Bolt later informs the Illuminati that the true purpose of the invasion is to find and kill Thane, an Eternal/Inhuman hybrid that Thanos had secretly fathered years earlier. Thanos is trapped in a pocket limbo of stasis by his son. Thanos is freed by Namor and was among the villains that joined his Cabal to destroy other worlds. Thanos later meets his end on Battleworld, where he is easily killed by God Emperor Doom during an attempted insurrection.

Investigating a temporal anomaly on Titan during "The Infinity Conflict", Thanos finds Pip the Troll and an older Eros who has come from the future. Eros tells him about an enemy made out darkness that will destroy Thanos in the future. Eros and Thanos craft a plan, but when they go to implement it Thanos is confronted by his future self who tells him to alter the plan to ensure his safety. The future Thanos then takes control of the past Thanos' body. Under the control of his future self, Thanos began searching through ancient temples and sites to find something that would allow him to eventually become like his future. Through his journey he was also forced to kill Adam Warlock who might interfere with his future's plan. After being unable to locate Eros, his future self tells Thanos that Eros was extremely important to his cosmic masterwork. Then after locating a moving comet Thanos goes to the comet which contained a treasure more powerful than the Infinity Gems. Despite the speed of comet being enough to immediately vaporize any being Thanos was able to get it since he "existed outside the norm". With this artifact Thanos was able to absorb every cosmic being that exists in his universe, eventually facing Eternity and Infinity. Despite their best effort Thanos defeats them and absorbs the two beings. He then merges with his future self finally taking the battle to the Living Tribunal and the One Above All. Facing the One Above All and the Living Tribunal, Thanos' future self went on to absorb both of them becoming the entirety of the Multiverse. As the multiverse began dying, while his future self searched for Eros, present Thanos was locked away within his future's psyche not allowed to interfere. In a desperate ditch effort to prevent all of this Eros, alongside Pip, travel to different points of Thanos' past and tell him he is not alone and that he is loved. However, it is all in vain as Thanos simply did not care, but these temporal paradoxes did allow present Thanos to use that little access of his future's power to talk to Eros through his past selves. He directs Eros and Pip to his future's psyche and had Eros free him, but unfortunately this allows future Thanos to finally find Eros and had him absorbed inside his universe. Then Adam Warlock came and refuses to free Thanos because he would end up as Eros and tells Thanos that trust would be the only thing that would stop future Thanos. As his future self saw that existence was just a never-endless cycle which trapped all beings decided to commit suicide and "free" everyone from this "torture". Thankfully, Kang prevented Eros from going to talk to Thanos' past selves which allowed him to avoid capture. This caused future Thanos to get distracted which allowed present Thanos to take control and reset everything prior to his future machinations, while erasing his future in the process.

Thanos is unintentionally brought back to the universe by Galactus.

When Thanos prepares to raid a Project Pegasus facility to steal a Cosmic Cube during the "Civil War II" storyline, he is ambushed and defeated by a team of Avengers who were tipped off by a vision from Ulysses Cain. During their battle, he mortally wounds War Machine and critically injures She-Hulk. After his defeat, he is imprisoned in the Triskelion, and manipulates Anti-Man into facilitating his escape. Thanos goes on a killing spree, but Black Panther, Blue Marvel and Monica Rambeau are able to stop him by devising a device that blocks the electrical synapses in his brain.

Thanos somehow later recovers during the "Thanos Returns" story and escapes captivity, and reclaims his Black Order forces from Corvus Glaive. After retaking command of his Black Quadrant outpost, Thanos discovers that he is dying. Thanos tries to force his father, Mentor, to find a cure for his malady, but kills him when he is unable to. Soon after Thanos would be battered and detained by the Shi'ar Imperial Guard after he invaded the very planet station of his father's facility sitting in their territory. A quick jump into the future shows Thanos's estranged son Thane having bested his mad father with the personification of death at his side. Presently locked within a maximum security cosmic Alcatraz, Thanos sits alone within a cell as his sickness ravages his body. All while being mocked by its prison warden whom he lured into a false sense of security to escape; ripping off his arm for escape access and murdering half his personal staff in a bid for freedom. Having narrowly escaped his imprisonment before its self-destruction, Thanos retreats to a hidden outpost where a roving mercenary colony loyal only to him was once stationed. Only to find it decimated at the hand of the new lover of Mistress Death; who reveals that she had stricken her former avatar with his fatal sickness, being his son Thane, now boasting the power of the Phoenix Force. Whom under her coaxing, had banished the mad titan back to the decimated Moon of Titan now entirely stripped of his godlike powers. For the next few months, Thanos would survive alone and all but powerless in the ruins of his home city. Surviving off the flesh of mutated vermin and being accosted by local scavengers who preyed upon him in his weakened condition, he is soon picked up by the unlikely crew of Thane's betrayed cohorts Tryco Slatterus, his adopted daughter Nebula and his brother Eros of Titan. Having heard of their plight, the three were dismayed to find Thanos stripped of all he was and had ever been; his second daughter only agreeing to come along so she could kill her father, immediately assaulted him. Starfox was able to preempt her attempt at patricide while inviting his wayward tyrant of a brother aboard their vessel. Thanos mentioned the only way for him to be relieved of his mortality was to seek out the God Quarry heralded by The Witches of Infinity. Starfox initially wrote this off as fable and folklore. Now on the path to the cosmic coven set at the edge of the known universe, Thanos and crew stop short of a black hole, knowing full well that it is where the witches make their home. The Mad Titan jumps into the pinhole of nothingness alongside his brother; having survived the crushing force of the singularity they dove into, Thanos and Eros are greeted by the Coven at the godly graveyard. Thanos demands the three that are one to return his godhood to him. Starfox tries his best to charm the enchantresses only to be rebuked by them, much to Thanos's joy when they prematurely aged him. Seeing as it was neither their place to destroy nor turn away those seeking them, The Witches profess the only way for the warlord to be made whole again was to climb down into the God Quarry and await a trial that would test his soul. Immediately after setting foot within the graveyard of old gods, Thanos is subsumed into the bedrock within which they rest. As his journey of the core being commenced, Thanos's trial began with him as leader of earth and the universes greatest champions, the Avengers. But he is unable to escape the nagging feeling that he has forgotten something, until the quarry itself wearing the guise of Falcon reminds him of who he used to be; tempting him to live as a hero and a man at peace for the first time in his immortal life. But Thanos laughs maniacally as he coldly rebukes such a path, ruthlessly killing his would-be friends and allies while choosing to remain whom he always was. His cosmic might returned to him, Thanos is freed from the God Quarry, wherein he immediately accosts his brother Eros and threatens the coven to release him from their domain so that he might do away with Thane once and for all.

Around the time of the New Thor's appearance, Thanos is approached by a mysterious hooded woman, who proposes an alliance. He tasks her with bringing him the hammer of the deceased Ultimate Thor. The woman fails, but removes her disguise to reveal herself as Hela, the Norse goddess of death. She tells Thanos that she needs his help to reclaim Hel, and in exchange, offers to give him the one thing he has been searching for his entire life: death. After this, the two kiss.

Some time after his battle with Thane during the "Thanos Wins" story, Thanos travels to the Chitauri homeworld. However, upon subjugating the planet, he is attacked by a being identified only as The Rider, who captures Thanos and uses a piece of the fractured Time Stone to bring Thanos millions of years into the future, where he encounters an elderly version of himself who has destroyed nearly all life in the universe. At first, Thanos believes it to be some sort of trick, but is convinced once the future Thanos utters the name Dione, which Thanos's mother had planned to name him before she went insane. King Thanos reveals he needs his younger self's assistance to defeat the Fallen One, the last being left in the Universe, so that he may finally reunite with Death. The Fallen One soon arrives, revealed to be a darkened Silver Surfer armed with the hordes of Annihilus and the deceased Thor's Mjolnir, using the latter to swiftly kill the Rider. The Surfer is distracted by the feral Hulk that Thanos kept chained in his basement, allowing the two Thanos to kill him using Surtur's Twilight Sword. Upon the Surfer's death, Death arrives, and Thanos realizes the true reason that King Thanos brought him into the future: so that King Thanos can finally die, reasoning that if he must die, it can only be at the hands of himself. At first, Thanos is more than happy to oblige his future counterpart's request, but quickly stops, disappointed at how pathetic and submissive his older self has become. Resolving to never become as pathetic and complacent as King Thanos has become, Thanos uses the fragment of the Time Stone and the Power Cosmic left in the Surfer's corpse to return to the present day. As the future begins to crumble around him, King Thanos realizes that his younger self has taken the steps necessary to ensure that this timeline will never take place. As he fades into nothingness, King Thanos asks Death what his younger self did, to which she simply responds "he won."

During the "Infinity Wars" storyline, Thanos later discovers that the Infinity Stones are being collected once again and begins plotting to reassemble his gauntlet. However, he is assaulted by Requiem, whom he apparently recognizes, and is quickly killed. She then destroys the Infinity Gauntlet and also commands the Chitauri loyal to Thanos to die.

In a prelude to the "A.X.E.: Judgment Day" storyline, Thanos is revived by Druig and Phastos as their plan to remove Zuras from his leadership after learning the Machine's purpose for their resurrection. Druig places a device inside his body to prevent his treachery. After receiving a vote from the Uni-Mind, Thanos becomes the Prime Eternal and kills Zuras for revenge and Druig to hide his weakness. He has Druig revived and visits his great uncle Uranos in the Exclusion where Thanos learns the Eternals' three principles. After Druig departs, Uranos gives Thanos an imprint key that enables an armory to access the fail-safe that Uranos put in. Thanos is told by the Eternal scientist Domo that his genes deriving from Eternals and Deviants are the reason why the Machine does not recognize him as an Eternal. As Thanos fights the Eternals, Druig betrays Thanos and activates the fail-safe in Thanos' armor which causes Thanos to die from his mutation. With Thanos gone, Druig becomes the new Prime Eternal.

Powers and abilities
Thanos is a mutant member of the race of superhumans known as the Titanian Eternals. The character possesses abilities common to the Eternals, but amplified to a higher degree through a combination of his mutant–Eternal heritage, bionic amplification, mysticism, and power bestowed by the abstract entity, Death. Demonstrating enormous superhuman strength, speed, stamina, immortality and invulnerability among other qualities, Thanos can absorb and project vast quantities of cosmic energy, and is capable of telekinesis and telepathy. He can manipulate matter and live indefinitely without food, air or water, cannot die of old age, is immune to all terrestrial diseases, and has high resistance to psychic assaults. Thanos is also an accomplished hand-to-hand combatant, having been trained in the art of war on Titan.

Thanos has proven himself capable of briefly holding his own in battle against Odin, and of blasting Galactus off his feet.

Thanos is a supergenius in virtually all known fields of advanced science and has created technology far exceeding that which is found on contemporary Earth. He often employs a transportation chair capable of space flight, force field projection, teleportation, time travel, and movement through alternate universes. Thanos is also a master strategist and uses several space vessels, at least three under the name "Sanctuary", as a base of operations.

Impact
In July 2018, the Reddit forum /r/ThanosDidNothingWrong, dedicated to sharing theories and memes about the character, went viral when it was announced that half of the forum's subscribers would be banned, mirroring Thanos’ plan to eradicate half of all life in the universe. The number of subscribers rose from 100,000 users in June, to over 700,000 on July 9, leading to over 350,000 users being banned, the largest such banning in Reddit's history. JV Chamar of Forbes stated that "Thanos did nothing wrong" has become a popular internet meme, and that the film Endgame provides some evidence in favor of this view, in particular when Captain America says, "I saw a pod of whales when I was coming over the bridge . . . There's fewer ships, cleaner water." The author notes that given the contemporary extinction crisis driven by human actions, "you could indeed argue that Thanos did nothing wrong — and in the long run, the villain might have actually saved the world."

Amalgam Comics
An alternate version of Thanos appears in the 1996 Amalgam Comics books published jointly by DC Comics and Marvel. Thanos was merged with Darkseid to become "Thanoseid".

Earth X
An alternate version of Thanos appears in the limited series Earth X. Thanos dwells in the Realm of the Dead with the entity Death.

Kid Thanos
After having witnessed a fight between the prehistoric Avengers and a younger Thanos, an alternate version of Doctor Doom called Doom Supreme is persuaded by Mephisto to put together a variation of the Multiversal Masters of Evil made from the evilest villains in the Multiverse and conquer it while saving Earth-616 for last. One of its recruits is a variation of the younger Thanos called Kid Thanos. Kid Thanos accompanied Doom Supreme in attacking Avengers Mountain. They fought Black Panther, Namor, and Valkyrie up to the point where Avengers Mountain exploded. Afterwards, both of them had spoken with Mephisto and Iron Inquisitor before rejoining with the other Multiversal Masters of Evil members so that they can get back to work.

In a flashback, Kid Thanos was with the Multiversal Masters of Evil when they attacked Earth-91.

Kid Thanos was with the Multiversal Masters of Evil when they attacked an unidentified Earth. Afterwards, they were attacked by Ghost Rider where he used his Hell Charger to knock down Kid Thanos and Hound.

Kid Thanos was with the Multiversal Masters of Evil when they arrived on Earth-616 during prehistoric times. During the fight between the Multiversal Masters of Evil and both Avengers teams, Kid Thanos fights Captain America and Prehistoric Moon Knight. 9 days later, Kid Thanos gets taken over by Black Skull's symbiote upon his defeat. With some power donation from Soldier Supreme of 1943, Kid Starbrand and Reno Phoenix of 1868, Ghost Ronin of 1655, and the Tyrannosaurus Starbrand of 66,000,000 BC, Echo defeats Kid Thanos.

As Kid Thanos finishes recuperating, Mephisto appears as he tells them what happened to Ghost Goblin, King Killmonger, and Black Skull while also mentioning that Doom Supreme and Dark Phoenix have fled. With the corpses of Ghost Goblin, Hound, and King Killmonger as well as the unconscious body of Red Skull near him, Kid Thanos states that he can obtain fresh knowledge of his teammates on his dissection table. Kid Thanos is told by Mephisto that Black Skull isn't dead yet.
