Thanos

"In time, you will know what it's like to lose. To feel so desperately that you're right, yet to fail all the same. Dread it. Run from it. Destiny still arrives."

- Thanos

Thanos, referred to as the Dark Lord by his most loyal underlings and the Mad Titan by the galactic community, is a powerful Titan warlord who rules over a distant region of space and commands two massive armies, known as the Chitauri and the Outriders. His own main objective was to bring stability from the universe, as he believed its massive population would inevitably use up the universe's resources and condemn it. However, his methodology to succeed was warped; through use of the ancient Infinity Stones, he intended to harness their power to exterminate half of all life in the universe.

He spent many years hunting down the stones and his desire to achieve his goal is what led him to forge deals with Loki and Ronan the Accuser in their respective campaigns against Earth and Xandar, as seen in his promising to aid them in exchange for an Infinity Stone. Both of these new alliances cost Thanos much of his resources, including one of the stones and the loyalty of his two daughters, Gamora and Nebula, and inadvertently resulted in the formation of the two superhero groups: the Avengers and the Guardians of the Galaxy. Fed up with these failures of his subordinates, Thanos has opted to seek out the six Infinity Stones himself. After a difficult, intense war for the Infinity Stones with the Avengers, Masters of the Mystic Arts, and Guardians of the Galaxy, despite sustaining a severe injury and almost being defeated, Thanos ultimately triumphed over his enemies with the finally completed the Infinity Gauntlet, using it to finally complete his goal and destroy half of life within the universe.

Fall of Titan
"When Thanos took my homeworld, he killed my parents in front of me. He tortured me, turned me into a weapon."

- Gamora to Star-Lord

Thanos was a member of the Titans, a race of powerful, god-like beings that evolved on a planet with which they shared their name. Thanos was born misshapen, bearing a physical mutation that left him marked as an anomaly amongst his people and therefore left him an outcast. Despite his status, Thanos sought to save Titan when the planet became threatened by an imminent catastrophic event. His idea, however, was considered too drastic and was dismissed by his people, which resulted in Titan becoming subsequently devastated as well as nearly uninhabitable. Another result of this devastation was that the Titan species was on the verge of extinction.

Sometime after Titan's fall, Thanos became a world-conqueror, moving throughout the universe and destroying half of the planets he conquered due to his ideology of balancing the universe by destroying half of all life. He became one of the most powerful and feared warlords, even ruling over a distinct region of space, and gaining control over the deadly army of the Chitauri.

Training his Children
"Flesh is weak. Weakness must be cast aside for the sake of power."

- Thanos Thanos collected orphans from each race that he conquered, such as when he massacred the Zehoberei race, as well as a Luphomoid family, to raise two young women from both races, Gamora and Nebula, to be devoted and deadly assassins. Usually, when Nebula lost in a duel against Gamora, Thanos removed a body part from her, which according to him was to make her stronger than Gamora. Aside from Gamora and Nebula, Thanos took in and trained other children as well, namely Corvus Glaive, Ebony Maw, Cull Obsidian and Proxima Midnight. The latter four warriors, more faithful and devoted to Thanos' command than Gamora and Nebula, comprised the Black Order. Thanos also acquired the services of the Other to act as his servant.

Quest for the Infinity Stones
With the destruction of Titan weighing heavily on his conscience, Thanos came to believe that the universe's large swell of life was depleting its finite resources, and would eventually cause the destruction of the universe itself. Deducing that the Infinity Stones, objects of immense power that held considerable dominance over the various forces that occupied the universe, could solve this issue, Thanos made it his life's goal to gather them, and forged several alliances in order to locate them. He successfully located at least one of the stones; the Mind Stone, which he then hid inside a Scepter that was capable of manipulating minds.

Through many years of searching, Thanos discovered a lead on the Orb's location, sending Nebula and Gamora to the Cloud Tombs of Praxius under Korath's command. Nebula fell victim to a trap during the mission, and Thanos, not one to tolerate failure, forbade Gamora from rescuing her. Nebula was forced to amputate her own arm in order to escape. The Orb was never recovered, but Thanos let the failure pass and resumed his search.

Chitauri Invasion


"The Tesseract has awakened. It is on a little world, a human world. They would wield its power, but our ally knows its workings as they never will. He is ready to lead, and our force, our Chitauri, will follow. The world will be his, the universe will be yours. And the humans, what can they do, but burn?"

- The Other to Thanos

Thanos discovered that the Tesseract was on Earth and allied himself with Loki in order to retrieve it, providing him the Scepter and his Chitauri army, who would help him conquer the entire planet in exchange for handing over the Tesseract to him. Through his intermediary, The Other, Thanos threatened the Asgardian god of mischief, saying that if he failed in delivering the Tesseract to him, Thanos would force him to endure a new kind of horrific suffering. Despite his vast army of the Chitauri and powerful weapons, Loki was defeated during the Battle of New York, and the Scepter-laden Infinity Stone came into HYDRA's hands, while the Tesseract was transported to Asgard by Thor, along with the now captured Loki. The Other reported to his master how the Earth's inhabitants were not as weak as they were thought to be. He also declared that challenging the Earth's heroes would be to court Death. Thanos rose to his feet and smiled at the prospect of what was coming.

Quest for the Orb


"Your politics bore me. Your demeanor is that of a pouty child. And apparently, you alienated my favorite daughter, Gamora. I shall honor our agreement, Kree if you bring me the Orb. But return to me again empty handed and I will bathe the stairways in your blood."

- Thanos to Ronan the Accuser

Sometime later, Thanos brokered a deal with his old ally, Ronan the Accuser of the Kree Empire, promising to lend a fraction of his forces in a genocide against the Xandarians in exchange for locating the Orb for the Mad Titan. Ronan and Korath the Pursuer quickly discovered the Orb on Morag and attempted to deliver it to Thanos, but the stone fell into the possession of a Ravager called Star-Lord who was trying to sell it to Broker before Ronan could claim it. Unwilling to be denied the stone, Thanos ordered Ronan to pursue Quill and recover the stone, sending Gamora to aid the Kree in his pursuit. Gamora found Quill first, cornering him on Xandar where he was attempting to sell the Orb. She recovered it, but what Thanos did not realize is that Gamora had chosen to cut all ties with him, due to the torture she and her many siblings have suffered through from the Mad Titan and planned to hand the Orb over to the Collector, who also sought the Infinity Stones for his own purposes. When Ronan relayed news of Gamora's betrayal to Thanos which he had learned had been planned for some time, the Kree berated the Mad Titan for not taking the situation seriously and even murdered The Other when he lectured Ronan on not showing Thanos respect. Undaunted by The Other's death and Ronan's complaints, Thanos turned Ronan away, instructing him to return to his task and correct Gamora's betrayal, which he was only slightly irked by. Thanos then instructed Nebula to take Gamora's place as Ronan's aide.

Ronan the Accuser's Betrayal


"BOY! I would reconsider your current course!" "YOU CALL ME "BOY"?! I will unfurl one thousand years of Kree justice on Xandar AND BURN IT TO ITS CORE!! Then, Thanos, I'm coming for you!"

- Thanos and Ronan the Accuser

Ronan the Accuser and Nebula both eventually stole the Orb from the Guardians of the Galaxy, but when Thanos was contacted by Ronan to be updated on their progress, he was furious to discover that the Kree, having experienced the true power of the Orb, intended on keeping the Infinity Stone for himself, despite Korath the Pursuer noting Thanos was the most powerful being in the universe. Nebula joined with Ronan, contemptuous towards Thanos after the horror he forced her to endure throughout her youth. Now believing himself superior to Thanos, Ronan promised to come after the Dark Lord when Xandar was destroyed. Unphased, Thanos cut contact with them without a word. Ronan would eventually lose his life at the hands of the Guardians of the Galaxy, who gave the Orb to the Nova Corps, making yet another Infinity Stone lost to Thanos.

War for the Infinity Stones
"Fine. I'll do it myself."

- Thanos

With both Loki and Ronan the Accuser having failed Thanos in their tasks of conquering worlds and bringing him the Infinity Stones, and both of his daughters lost to him, Thanos had finally grown tired of the lack of progress in his crusade and decided to take matters into his own hands. Thanos forced the dwarves of Nidavellir to forge the Infinity Gauntlet in order to control the power of all the 6 Infinity Stones at once and then began to hunt for the Stones himself, believing himself to be capable of completing the task while smiling confidently to himself at the prospect of victory. During his hunt, Thanos abandoned his armour in favour of more practical clothing.

Acquiring the Power Stone
Sometime before encountering Thor and the Asgardians, Thanos went to Xandar and massacred the entire planet and retrieved the Orb from the Nova Corps.

Obtaining the Tesseract
"Let him have his fun"

- Ebony maw

With his ship, the Sanctuary II, Thanos tracked down the ship carrying the Asgardian survivors of the cataclysmic Ragnarök on their way to Earth, Loki and his brother Thor among them. After killing Loki for failing him during the Chitauri Invasion, Thanos claimed the Tesseract and retrieved the Space Stone from it.

Interrogating the Collector
Thanos had arrived on Knowhere long before the Guardians of the Galaxy could and after killing the Collector and retrieving the Reality Stone, having predicted the arrival of the Guardians, tricks them successfully with a realistic illusion conjured by the Reality Stone that made it look as if he was still torturing the Collector and was caught off-guard and killed by Gamora. Quickly revealing himself, he easily defeats both Drax and Mantis and restrains Gamora. When Gamora begged Peter to kill her, Thanos simply used the Reality Stone to turn it's ammo into bubbles and teleports away.

A Tragic Sacrifice
Back on his ship, Thanos demanded Gamora to tell him the location of the Soul Stone, but she refused. However, Thanos forced Gamora to reveal that the stone is on Vormir by torturing her sister Nebula. Gamora and Thanos travel to Vormir where they meet the Stonekeeper, who guided them to the top of a nearby cliff. The guardian of the Soul Stone explained to Thanos that obtaining the Stone requires the sacrifice of a loved one. Upon hearing this, Gamora mocked Thanos as heartless and uncaring, but Thanos, having truly loved Gamora as his daughter, sheds tears that he would have to kill her. Although Gamora desperately attempts suicide, Thanos used the Reality Stone to turn Godslayer into bubbles and then threw her off the cliff still in tears. He then obtains the Soul Stone.

Battle of Wakanda
Having obtained the powers of the Time, Space, Reality, Soul and Power Stones, Thanos arrives on Wakanda to retrieve the final Infinity Stone, the Mind Stone. Even with all of his army destroyed, Thanos with the nearly complete Infinity Gauntlet is now far too powerful for all of his opposers and effortlessly defeats and incatipates them. Despite Maximoff's tearful sacrifice of Vision to destroy the Mind Stone, it is for naught as Thanos simply uses the Time Stone to rewind to before Vision's death and then forcibly carves it out, finally completing the Infinity Gauntlet.

Universal Genocide Complete
"He did it..."

- Nebula

Almost immediately after completing the Infinity Gauntlet, Thanos was engaged by Thor. Shooting an energy beam at the Asgardian, Thor managed to deflect the blast with Stormbreaker as he charged at him, successfully lodging the axe part of the weapon into his chest. Despite being severely wounded, Thanos is undeterred, musing to Thor that he should have aimed for his head, as he weakly activates the Infinity Gauntlet. Before Thor can react, Thanos snaps his fingers, releasing a burst of light. When the light fades, Thanos is mysteriously healed and in a landscape where he meets a young Gamora and when she asked him the cost of his goal, he solemnly said it cost him everything. Thanos then teleported to another planet as his goal to wipe out half the life of the universe unfolded. Having at last accomplished his objective, Thanos sat to enjoy a sunset.

Personality
"Fun isn't something one considers when balancing the universe. But this... does put a smile on my face."

- Thanos

Thanos is nothing less than the ultimate personification of sadism, cruelty, megalomania, infinite destruction, death, power, and madness as shown by his searching for the Infinity Stones with the apparent goal of controlling all of existence. He desired to use the Tesseract to look beyond the known worlds to find greater ones that it would unveil. He is also relentless as seen by finding children to take as his own so he can raise them as assassins while forcing them to watch as he murders their families and highly intimidating, as Ronan the Accuser was visibly fearful in his presence and Loki doing so at the mere mention of him, as well as being able to command the Chitauri and Outrider armies, both being highly savage and powerful creatures, unchallenged.

He is unforgiving of failures; The Other warned Loki that he would know a new kind of pain if he did not give them the Tesseract, Thanos threatened to bathe the starways in Ronan's blood if he failed to deliver the Orb and forbade Gamora from rescuing Nebula when the latter fell into a trap whilst on a mission in the Cloud Tombs of Praxius. He has little to no regard for his followers, showing absolutely no empathy when Ronan killed The Other and referring to Gamora as his "favorite daughter," even with Nebula present.

He inspires no love, as he is despised by his own "daughters," Gamora and Nebula. Raising them in a brutal way, Thanos would pit them against each other in the hope that Nebula would beat Gamora; however, when Nebula lost, he would remove parts of her in order to make her stronger, taking her apart piece by piece and replacing her with artificial limbs and organs so she would be able to defeat her sister. He is also manipulative and mistrustful, sending Ronan to retrieve the Orb for him and not telling him that it contained an Infinity Stone. He keeps a low profile, lurking in the shadows and making others do his work for him. However, he is fully willing to take action when necessary or having had his patience pushed to its limits, as after both of his alliances backfired, he decided to hunt for the Infinity Stones himself. However; he is shown to love his adoptive daughter Gamora as he is shown crying when he realizes that to get the soul stone he must through " a loved one" off the cliff, knowing the only one he loves is Gamora and then again when Peter asks where she is.

He is also highly confident, to the point of borderline arrogance, as he was shown to be smiling when The Other told him challenging the Avengers would be like courting Death. He was even unfazed at the idea of Ronan powered by the Power Stone coming after him despite knowing well that Ronan was already very powerful even without the Stone and the fact that he was backed up by Nebula who had betrayed him, displaying only anger at the betrayal. He also smiled confidently after deciding to hunt for the Infinity Stones himself. Whilst he claims his mission of “balancing the universe” puts him above pleasure or enjoyment, Thanos ultimately considers his quest for the Infinity Stones and the attempts of the Avengers to stop him “fun” and “put a smile on [his] face."

Even though he was shunned by his own people for a hideous mutation he bore, he ultimately cared for them even though he was ostracized. His plan for saving his homeworld was rejected and thus lead to the fall of his race. This incident would have presumably turned him into the being he is now today and the hardships he suffered might have been the reason he tortured Gamora and Nebula and not actually caring for them. However, it is revealed that while Thanos oddly did not care at all for Nebula and cruelly tortured her without mercy, he did truly love Gamora and cried when he pushed her to her death.

Thanos has also shown himself to be surprisingly honorable, as he did not kill Iron Man after acquiring the Time Stone as he promised to Doctor Strange and instead simply left Titan. He also wished that people would remember the heroism and will that Iron Man fought with if he was removed from existance once he used the Infinity Gauntlet

Despite his malicious and dark nature, Thanos believes that he was born with only one destiny: to save the universe from itself. He speaks of wanting to wipe out half of the universe to create balance, even stating that half of humanity will be spared from destruction.

Powers and Abilities
"Master, you cannot! Thanos is the most powerful being in the universe!"

- Korath to Ronan

Powers
Since he prefers to manipulate events through emissaries, Thanos has not demonstrated much of his powers at this point. However, it is conceivable that he is terrifyingly powerful, as he is able to easily intimidate other formidable beings such as Loki, Ronan the Accuser and Hulk. He also rules the powerful Chitauri army unchallenged. Korath fearfully acknowledged that Thanos is the most powerful being in the universe. When Nebula told Gamora that she planned to kill Thanos, Gamora plainly told Nebula that she didn't know if this was possible. Thanos's power is so great that he can easily handle the power of the Infinity Stones, which speaks for his immense power as very few could do such a feat and most of them showed great difficulty in wielding the Stones. He holds this much power and reputation even without possessing the Infinity Stones; according to Gamora, he would be capable of "[wiping] out half the universe" with a simple snap of his fingers if he were to obtain all six of them.
 * Superhuman Strength: Thanos's physical constitution has displayed a tremendously high level of supernatural strength, as he is easily strong enough to crush the Tesseract with just a single hand to retrieve the Space Stone. His strength allows him to physically overpower, lift, restrain, and knock down even those like Hulk and Thor with his full powers unlocked. Indeed, he was able to effortlessly beat Hulk to bloody pulp, wound Thor badly with few punches and almost killed him by squeezing his head, and easily strangled Loki to death with one hand. His strength is even great enough to allow him to easily wield the Infinity Stones without suffering any strain, something that very few could do. Though he initially struggled and was overwhelmed by the combined efforts of Iron Man, Spider-Man, Doctor Strange, Drax, Nebula, Mantis and Star Lord, he was eventually able to overcome them and regain control of the Infinity Gauntlet, proceeding to defeat the said team.
 * Superhuman Durability: Thanos's physical constitution grants him tremendously high levels of supernatural resilience and durability, rendering him capable of easily handling the Infinity Stones with the Infinity Gauntlet without any strain or harm done to himself, a feat that very few, such as the Celestials, have been seen capable of. Unarmed blows from beings like Thor and Spider-Man barely stagger him. While wearing his armor, he is completely unfazed and unharmed by Hulk's blows, who was capable of destroying a gigantic Leviathan with a single punch. He only received a slight cut on his face after repeated full power blows from Iron Man's nanosuit. His durability is great enough that it took a surprise attack from a fully powered Thor wielding Stormbreaker, a weapon enchanted to cut through anything, to finally severely wound him by lodging the blade directly in his chest. Even then the otherwise fatal wound was not enough to stop him from using the Infinity Gauntlet.

Infinity Gauntlet
After equipping the Infinity Gauntlet into his left arm, combined with his already immeasurable powers, Thanos was able to safely harness the supernatural powers of all the six Infinity Stones, gaining dominion over the fabrics of reality the stones represented as well as becoming so powerful that he was able to destroy half of life in the Universe by just snapping his fingers. So far he has shown he following supernatural powers.
 * Energy Manipulation: After inserting the Power Stone into his Infinity Gauntlet, Thanos is granted the stone's power to project extremely powerful purple, fire-like energy and used it to unleash powerful energy beams in his fight on Titan and even projected an Omni-directional shockwave of energy when he tears through his opposers to retrieve the Mind Stone. He was also capable of using the destructive energy of the Power Stone to destroy planets such as Xandar and charge objects to quickly destroy it, as he did to the Statesman causing it to explode shortly after.
 * Force Field Generation: Using the same energy from the Power stone, Thanos could generate extremely strong force fields capable of easily deflecting repulsor beams from Iron Man in his Mark XLVIII and instantly vaporizing bullets upon contact.
 * Regenerative Powers: After Thor made an attempt at Thanos's life with the Stormbreaker, he managed to severely wound him. After the weakened Thanos activates the Infinity Gauntlet, a large burst of light emerges which knocks Thor away and Thanos was completely healed.
 * Telekinesis: After inserting the Space Stone into his Infinity Gauntlet, Thanos gains vast telekinetic powers, to the point that he was capable of ripping apart portions of Titan's moon and hurling them as meteors. He could also effortlessly levitate and throw many heavy objects, as he easily interfered with War Machine's flight by holding him down with large amounts of debris, as well as casually throw and restrain others with his telekinesis, as he easily sent Okoye to the ground before she had a chance to attack him with her spear.
 * Portal Creation: After inserting the Space Stone into his Infinity Gauntlet, Thanos is granted the power to open gateways to any part of the universe, effortlessly going to Titan and later Wakanda without the need for a spaceship.
 * Time Manipulation: After inserting the Time Stone into his Infinity Gauntlet, Thanos gains the ability to manipulate time itself. He was able to use the stone's dominion over time to resurrect Vision and recreate the Mind Stone, even after Wanda had destroyed both.
 * Reality Manipulation: After inserting the Reality Stone into his Infinity Gauntlet, Thanos is granted the supernatural power to have dominion over reality itself.
 * Illusion Conjuration: Thanos can create realistic illusions, as he created a vivid hallucination to fool Gamora, Starlord, Drax and Mantis into believing that he was torturing the Collector for the Reality Stone while in actuality he had already acquired it and had killed the Collector before they arrived in order to ambush them.
 * Matter Transmutation: He can even warp reality to the point of being able to easily transform weapons into harmless substances, as he instantly turned Star-Lord's ammo within his gun into a flock of bubbles before he had a chance to shoot and did the same with Gamora's sword before she attempted to kill herself.
 * Ground Manipulation: Thanos also can use the Reality Stone to manipulate the earth, as he easily made large concrete pillars rise from the ground to keep Black Widow in place.
 * Dematerialization: He is capable of dematerializing anything, like Bruce Banner and the Hulkbuster when he tried to attack him.
 * Death Inducement: With the combined powers of all of the Infinity Stones and with a snap of his fingers, Thanos was able to force half of the universe, including the majority of the Avengers, to die.

Abilities

 * Master Manipulator: Thanos is an exceptional manipulator, as without leaving his throne, through only the manipulation of other powerful beings, easily deceiving even the extremely intelligent and skilled manipulator Loki into doing his bidding, he ultimately caused both the Chitauri Invasion and the Battle of Xandar. As Thor noted, Thanos has effectively manipulated the Avengers for his own goals.
 * Master Leader: Thanos is an exceptional leader, as he was able to lead the Outriders and Chitauri armies despite their savagery and power unchallenged and inspire absolute loyalty into his Black Order children. Thanos's outstanding leadership was displayed by the fact that he was known for having led his forces with such effiency as to having easily decimated many species and killing half of said species during his mission to rebalance the universe.
 * Master Combatant: Thanos is an exceptionally accomplished hand-to-hand fighter, with millennia worth of fighting experience. Thanos's skills allowed him to easily defeat and beat Hulk, the former undefeatable champion of the Grandmaster's Contest of Champions, to a bloody pulp and defeat Thor, the second greatest warrior in Asgard's history surpassed only by Odin, without much effort. He later easily defeated and grievously wounded Iron Man and was about to kill him until Strange made a deal to surrender the Time Stone in exchange for Thanos to spare Tony's life.
 * Genius-level Intelligence -  Even at his youth, Thanos was deemed a genius among his kind despite his deformation. His long life allowed Thanos to refine his intellectual appitude to the highest degree, making him exceptionally intelligent. While hiding in the shadows, Thanos's intelligence allowed him to create extremely complex and well-coordinated plans and execute them effectively, giving the Avengers and Guardians of the Galaxy great trouble all the while remaining anomyous. Thanos was even capable of surpassing the incredibly smart Loki, something few were able to do, as he easily tricked the God of Lies into becoming his minion and later easily predicted Loki would attempt a sneak attack and countered it casually and killed him.
 * Indomitable Will: Thanos's willpower is vastly strong. Despite being devastated by the destruction of his planet and species, Thanos was able to recover and became very determined to balance the universe by wiping out half of the life in the universe. With his unwavering belief, he devoted most of his lifetime on the goal of balancing the universe. Thanos's will is so strong that Mantis' power failed to completely sedate him and he even managed to eventually overcome it, something even a Celestial was unable to do.

Weapons

 * Infinity Gauntlet: A catalysmically powerful item that Thanos stole to allow him to channel the power of all the six Infinity Stones. He would successfully complete the Gauntlet and use it to wipe out half of the universe.

Other Equipment

 * Space Throne: Thanos' stationary home, he was accompanied by The Other until he was mercilessly killed by Ronan the Accuser.
 * Sanctuary II: A gargantuan spaceship commanded by Thanos.
