Thanos

Thanos appeared in 1972 Marvel Comics called Iron Man.

Thanos was one of the last sons of A'Lars, progenitor of the second colony of Eternals on Titan, and Sui-San, the last survivor of the original settlement of Eternals in this moon. He was born with purple, hide-like skin and a massive body due to his Deviant Syndrome. The very first time his mother laid her eyes on the baby, she was driven mad and tried to kill him.

After that, the Cosmic Ghost Rider from an alternate future came to kill the baby, but when the Penance Stare didn't work on Thanos, the Rider decided to take the baby under his wing and change the future. The Rider tried to convince Galactus to help him raise the baby, but the cosmic being refused and instead wanted to kill the baby himself. With the Watcher bearing witness, the Rider vowed to raise the baby on his own, creating an alternate timeline where Thanos grew to become an interplanetary dictator. The Guardians of the Galaxy of said timeline tried to prevent their future by stopping Frank, but he, and eventually baby Thanos, killed them all. They were subsequently greeted by Thanos' future self, who sported the same clothes Frank used as the Punisher. He brought both of them to his future, showing Frank the authoritarian world he had built on his example, including a past version of himself living with his wife Maria. Realizing the consequences of his intervention in his life, Frank killed the future Thanos and returned his baby self to the past, erasing the alternate timeline. Death appeared before Frank to confirm that his actions had nonetheless instilled the baby Thanos with the bloodlust that would make him her agent.

Thanos grew up to have an introvert nature, but despite this and his unusual appearance, Thanos was well accepted by his peers. He was a mild-mannered intellectual that dreamed of becoming a scientist like his neglectful father. However, signs of his true nature started to creep up early on. For instance, he liked to draw dead animals despite vomiting at the prospect of performing a dissection. Thanos' life reached a tipping point when a mysterious girl convinced him to explore with his friends a dangerous cave to overcome his fear of killing. A cave-in separated Thanos from his friends for three days, during which he refused to even think of murdering the inoffensive creatures that lurked underground for sustenance. When he found his friends, they had been killed by the animals living in the caves. After Thanos returned to society, the same girl convinced him to go back to the cave and slaughter the critters in revenge.

By the time he was a teenager, Thanos excelled academically and learned faster than he was ever taught. He began to vivisect creatures in secret in order to gain knowledge while searching for an answer to his abnormal genetic makeup. The girl that had helped him overcome his fear of killing became his confidante. Thanos' search for answers escalated into killing fellow Titanians, carrying out the first murders in the history of Titan. Despite declaring that his first two murders were going to be the last, Thanos eventually killed again, and found out that he enjoyed it. Thanos fell in love with his confidante, who enabled and further motivated and Thanos' actions, but she rejected his advances.

After murdering seventeen people in total, Thanos killed his mother in hopes of finding in her body the key to who he was, both spiritually and physically. At some point, Mephisto approached Thanos and convinced him to go to Earth and fight the Prehistoric Avengers. Thanos was later recruited by Doom Supreme from alternate universe alongside other powerful versions of notable villains into the Multiversal Masters of Evil. He and his fellow Masters would travel through the multiverse and destroy the Prehistoric Avengers of each universe in order to rewrite the future and conquer them despite the interference of the Deathloks. However, when finally invading Earth-616, they were met with resistance from the Prehistoric Avengers and the present day Avengers, leaving Doom to betray them and forcing both Thanos and Dark Phoenix Mystique to escape. Thanos informed Mephisto that their plan had failed but he revealed that he had been siphoning the energies of the universes they had conquered and intended to conquer the First Firmament. Following this, Thanos would return to his present time.

He left Titan afterwards, swore off killing, and found a menial job with a pirate crew with whom he explored the cosmos. As years went by, Thanos became detached and unemotional. In many different planets, he would find a partner and mate with them in hopes to feel something again, to no avail. He always abandoned them and the babies they bore him. Thanos eventually came into conflict with his captain in the pirate crew due to his disinclination for murdering. In an act of complete instinct, Thanos slaughtered him, and subsequently seized control of his crew.

Thanos decided to embrace his murdering nature and returned to Titan in secret. He was approached by his old confidante and tried to court her again. She demanded that Thanos proved he belonged only to her, so he embarked on a journey to kill all of his offspring and razed every planet they stumbled upon for the sake of his love for death. Additionally, Thanos experimented on his own body, granting himself a variety of powers. Thanos' confidante became his companion, and eventually declared that for her to love Thanos, he would have to become a god, a supreme destroyer above all else. After Thanos discovered that none in his crew could see her, she revealed her true nature, that she was the physical manifestation of Death itself. Driven mad by this revelation, Thanos gave in to Death's promises of romance and used his fleet to ravage Titan. Once his armada bombarded Titan, Thanos personally descended to murder the survivors. He was confronted by the elder A'Lars, who managed to make Thanos doubt whether Death was actually by his side or if he was simply demented. Thanos spared his father solely so he could watch his son defile the cosmos and prove his sanity. Death finally kissed Thanos, but he found her embrace to be cold. Without his thirst quenched, Thanos continued his journey of destruction.

Thanos is extremely prideful, violent, deceptive, malevolent, treacherous and ruthless to the point that he doesn't care about sacrificing innumerable planets and civilizations, even his own race, in order to praise Death and gain its affection. Thanos also possesses an insatiable hunger for power, always seeking to obtain objects of incalculable might & influence, such as the Cosmic Cubes or the Infinity Gems. However, Thanos often speaks in a sophisticated manner with a calm and collected demeanor, described by the Silver Surfer as professorial. Thanos has also shown an appreciation for farming and seeking knowledge.

Despite his overall megalomaniacal; if not outright omnicidal personality, Thanos doesn't wish to destroy everything. Even willing to join forces with heroes when he perceives a threat more dangerous than himself. He worked together with Adam Warlock to stop Magus and the Goddess, teamed-up with Thor and Genis-Vell to defeat Walker, teamed up with Adam Warlock, Gamora, Spider-Man and the Defenders to defeat the Thanosi clones, thwarted the Hunger entity with the help of Galactus, helped the Guardians of the Galaxy in order to stop the invasion of the Cancerverse, and worked with Deadpool to release Death from Eternity's prison. He also has a genuine respect for Mar-Vell and Adam Warlock. Thanos even helped Mar-Vell in his journey to the afterlife, and he once considered Adam his only friend. In spite of all this, however; Thanos is still a rather malignant individual at his core. Taking a rather sadistic glee in how he goes about massacring as well as demoralizing whole planets and/or their individual life-forms from time to time.

Like how he prevented a human college student from bringing about world peace through subtle changes to events that had brought it about, or when cruelly tormenting another earthborn from infancy to adulthood with a plague of cruel happenstances he was blamed for, going so far as to set Kehlrassian farmers upon one another when after murdering their god and sabotaging his system of virtuous rebirth for sick and demented amusement. He can also be rather pragmatic in regards to evil, seeing more value in conquering and bridging the Earth with the wider galactic community when approached by a fledgling tithe of universal powers that attempted to recruit him in annihilating it. Given how countless greater forces than a clandestine cabal of underversal players have tried to decimate that wild and unruly planet; and failed time & time again, himself included.

Powers and Abilities

• Titanian Eternal Physiology: By far the strongest and most powerful Eternal from Titan, Thanos is a superhuman mutant whose massive, heavy-bodied form was born with the capacity to synthesize cosmic energy for certain personal uses. The mad titan has increased his powers through bionic amplification, mystical enhancement and as a result of being resurrected by Death itself. He was deemed a Category 1 Life Ender by the Nova Corps, to have an "universal" threat level and to have been a one-time reality ender. Being seemingly categorized as a Cosmic-level threat, being sent by the Shi'ar Imperial Guard to the core cell of a galactic gulag.
• Superhuman Strength: Thanos possesses vast superhuman strength the full limits of which aren't known. Death has increased his strength beyond the original limits to levels where he is far surpassing those of the physically strongest Eternals. He has proven capable of fighting Thor even when Thor had the Power Gem. His strength is so vast that he has been able to defeat the likes of the Silver Surfer, punch away an attacking Hulk, physically subduing with ease Beta Ray Bill and Ronan the Accuser (as well as casually breaking apart the latter's Universal Weapon) and, most impressively, tango with the mighty Tyrant. He was also able to beat in melee fight the Hulk power-enhanced Annihilus. Thanos can also augment his strength with his cosmic energy when needed but doing it rarely as his own power is mostly enough. Thanos was also able to lift the Galactus Engine and recover it from the depths of Ego the Living Planet, destroy a planet in a battle with Drax (in his first incarnation), he was even able to fight hand-to-hand with a Phoenix Force empowered Thane with amped with the God Quarry. Thanos punched Thane into the planet they were fighting above and destroyed it by charging through him.
• Superhuman Agility: Despite his great size, Thanos' agility, balance, and bodily coordination are enhanced to levels that are beyond the natural physical limits of the finest human athlete. His agility is roughly equal to that of the average Eternal. He was able to dodge a Power Gem enhanced Champion of the Universe.
• Superhuman Reflexes: Thanos' reaction time is enhanced to a level that is beyond the natural physical limits of the finest human athlete. Like his agility, his reflexes are about average for an Eternal.
• Superhuman Stamina: Thanos' musculature produces almost no fatigue toxins during physical activity. As a result, he has nearly superhuman stamina in all physical activities.
• Nigh-Invulnerability: Before his "death", Thanos possessed an impressive degree of resistance to physical injury, even compared to other Eternals. After his resurrection, Death increased his ability to resist injury to a much greater degree and he is now nigh-invulnerable. He has withstood, at point-blank range, planet-destroying attacks without any harm. He has withstood blasts from the Silver Surfer to point-blank range - unharmed. He withstood a battering from an enraged, Power Gem-wielding Thor with nothing but a bloody nose. He possesses such an incredible resistance to injury that he has been shown to survive point-blank blasts from Odin, and Galactus. Thanos has withstood three full screams from Black Bolt, one at point-blank range, without any significant damage aside from damaging his suit, survived being subjected to an artificial 2-light year wide black hole, and withstood being stabbed in the chest by Wolverine's Adamantium claws without exhibiting any discomfort.
• Immortality: Thanos, like all Eternals, is immortal in the sense that he is immune to all known diseases and infections and is immune to the effects of aging. Thanos is banned by Death itself from entering its realm, rendering him truly immortal. He is able to die but he will always return, no matter the severity of any injury.
• Regenerative Healing Factor: Despite his extraordinary durability, it is possible to injure Thanos. Like all Eternals, however, Thanos is capable of regenerating damaged tissue with much greater speed and efficiency than a human being. His healing powers aren't as developed as those of some Eternals. Some Eternals are capable of regenerating any destroyed tissue. Given the circumstances of his death at the hands of Drax the Destroyer during the Annihilation event, Thanos is unable to regenerate missing organs, such as a heart.
• Energy Manipulation & Projection: Thanos has displayed great versatility in the use of his energy projection abilities. He has demonstrated the ability to project pure energy as a concussive force, "magnetic" energy, infrared heat-beams from his eyes, and disruptor beams, unilaterally striking separate targets with his optic blasts, as well as using his mental link to his techno-mystical chair to form vastly powerful energy shields, barriers, and force-fields but proven himself to be able to project some form of shields and barriers on his own. The exact extent of Thanos' energy projection abilities are unknown, but his blasts have been capable of knocking down the likes of the Hulk and Thor, and to temporarily defeat four alternate incarnations of the Silver Surfer with a simple casual blast. He was also able to graze Galactus armor and blast the Devourer of Worlds off his feet and send him across the moon. By collaborating with the In-Betweener they together released the latter from his prison created by Master Order and Lord Chaos.
• Telepathy: Thanos possesses strong psionic abilities. His mind is invulnerable to most forms of psychic attack and proven to be immune to mind gem. Thanos has demonstrated the ability to successfully defend himself against psychic assaults from Moondragon, and Mantis. He also managed to shut down the Maker's mind, turned the Fallen One into his herald made the Hulk attack his fellow Avengers, and forced Conner Sims (the Anti-Man) to destroy his surroundings. Thanos also once attempted to destroy the mind of Drax the Destroyer with a powerful psychic attack called the Time-Mind Sync Warp, that plunges the victim's mind into a psychedelic dimension of insanity, causing death or incapacitation.
• Matter Manipulation & Control: Thanos has demonstrated some ability to manipulate matter on the atomic level, similarly to Earthborn Eternals. On one occasion, he turned the Skrull Skragg, into stone. He also used his matter manipulation ability on Moondragon to purge the muscle controlling parasites implanted by Annihilus from her body.
• Mystic Capabilities: Thanos is skilled in magic, as he has cursed Deadpool with immortality.
• Flight: Thanos has shown that he is capable of flying.
• Teleportation: Thanos can teleport himself across unknown distances through his link with his techno-mystical transport chair. Like all Eternals he is also able to teleport on his own. When stranded in space with Terraxia, he could neither fly, nor teleport to his rescue, presumably because his chair got destroyed in the struggle before.
• Super-Genius Intelligence: Possibly Thanos' most dangerous ability is his mind. Thanos' intellect is dedicated to enhancing his own powers and to the annihilation of all life. Thanos is a genius in virtually all known fields of advanced science and has created technology far exceeding contemporary Earth science. He has also shown to quickly adapt to new battle situations, as shown in his fight with the Champion of the Universe, who outclassed him physically and whom he beat by dancing around him, blasting him with energy attacks and tricking him into destroying the planet they fought on. Thanos has remarked that, compared to himself, Bruce Banner's intelligence is only great for human standards.
• Skilled Unarmed Combatant: Although he typically avoids physical combat, Thanos is a highly formidable hand to hand combatant, having been trained in the Arts of War on Titan and having millenia of combat experiences. He is particularly skillful at using a combination of his physical and energy manipulative abilities during combat. He is also a skilled swordsman, being able to overwhelm a Mjolnir-wielding Silver Surfer.
• Mystical Knowledge: He also has great knowledge of arcane and mystical lore.

Arsenal

• Robotic Drones: Thanos has designed several different types of robotic drones to serve his needs. These drones carry out many functions, including maintenance, manual labor, record-keeping, and security. These robots come in many shapes and sizes dependent on their purpose.
• Time Machine: Thanos has been shown to have possessed a time machine, which he referred to as a "Time Probe". The present-day status of this machine is unknown.
• Stasis Rifle: An experimental weapon capable of generating a cube of pure force, which envelops the target and places them into near-complete physical stasis. This stasis cube was capable of holding the insane, power-gem enhanced Thunder-God Thor. The experimental version of this weapon carried charge enough for only one blast.
