Thanos

Thanos is one of the major characters from the Marvel comics.

An Eternal with the Deviant gene which makes him unique and extremely powerful, even amongst his own kind. Above all else, Thanos loves and worships Mistress Death. Few can equal his intelligence, strength and ambition for power. Thanos has wielded the Cosmic Cube, the Infinity Gauntlet and even the Heart of the Universe.

Personality
Thanos is extremely prideful, violent, deceptive, malevolent, 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 power, 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 megalomaniac 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.

Abilities
Being an Eternal, Thanos has superhuman strength, endurance, reflexes and agility. He is nearly invulnerable, able to endure extreme heat, cold, energies, radiation, and poisons. Due to his genetic heritage, Thanos is immune to aging and disease. Being one of Mentor's oldest children, Thanos' birth is estimated to the around 4000 B.C. Thanos could survive indefinitely without food or water even before Death "cursed" him with immortality. After Death resurrected Thanos, she increased all of his abilities, giving him even greater resilience and energy manipulating abilities. He is exceedingly powerful, tiered with individuals like Odin. Thanos' powers have increased to unknown levels, but it's a massive upgrade from his previous form.

Superhuman Strength
Thanos amplified his own abilities during his early life, prior to his published appearances. His physical attributes are considered exponentially superior to those of other Eternals. He is one of the strongest beings in the universe, being able to lift far in excess of 100 tons without any effort, and has destroyed entire planets with the simple force of his blows. His strength has enabled him to challenge and defeat several of the absolute strongest beings in the universe. He physically subdued Beta Ray Bill, and beat the Silver Surfer within an inch of his life, and has proven capable of fighting Thor even when he had the Power Gem. An attacking Hulk was sent away with a single blow from Thanos, and Thanos has easily defeated Ronan the Accuser as well as ripping the Accuser's Universal Weapon apart with his bare hands.

Invulnerability
Thanos possesses remarkable resilience and durability and has brushed off physical attacks from traditional powerhouses such as Thor and Drax. He was even able to trade blows with a maddened Thor in possession of the Power Gem with only a bloody nose, and was enjoying the fight, until he froze the Thunder God in a block of pure energy, using an experimental weapon. Perhaps what is even more impressive is Thanos' durability to Energy based attacks. Thor hit him with 2 massive lightning strikes and seemed unaffected during Infinity. He has taken a full power blast from the Silver Surfer without so much as flinching, and seemed unaffected by Odin's blasts until the latter called on his enchanted spear to amplify his power. Even after that, Thanos was not defeated, although Odin had the upper-hand in the battle. He has survived attacks from top tier abstracts, including Kosmos, Omega, and even Galactus, although with the latter two, this was done with the aid of his personal shields. He is even highly resistant to reality and matter manipulation as shown in his travels during the Thanos Quest in Nexus of reality. He also has withstood screams from Black Bolt at point blank range with only little damage.

Energy and Matter Manipulation
Through meditation and certain mystical techniques, Thanos augmented his power in still other ways, enabling him to tap, transform, and direct vast quantities of cosmic energy for destructive force. He can emit blasts of plasma and cosmic energy of devastating power from his eyes and hands. A example of this was blasting a well fed Galactus with such force, he sent him flying out of his own ship and flying halfway across a planet- though Galactus didn't sustain injury. Thanos has also destroyed his son Rot, in a blast so powerful it made the universe scream. His energy blasts have also been able to effortlessly KO the Thing and considerably hurt Thor. He was able to damage fully an enraged Hulk with his energy attacks that he almost knocked him out and Hulk needed time to recover even with his powerful healing factor. Thanos is also able to manipulate matter and other energies to his own purposes, such as in shields which are not tied to his technology. More interestingly, he was able to rearrange the Fallen One's brain on the atomic level to lobotomize and mind control him, as well as heal Moondragon of a supposedly fatal disease just by touching her.

Force Field Creation
Thanos is capable of creating force fields around himself or other objects or beings. Although he usually does this with the use of tech he proved to be capable of doing that on his own. Those force fields are so durable that they were capable of easily taking a blow from enraged Hulk and hold of Champion for a time (who at the time was wielding power gem). Thanos can use his superhuman reflexes to trap beings or objects travelling at high speeds. He was capable of stopping Mjolnir in a force field thrown at him by Thor and was also able to stop Beta Ray Bill's hammer Stormbreaker.

Telepathy
Thanso has powerful Psionic Abilities. He has proven to be even more powerful than Moondragon and has even entered into the mind of Galactus and battled him astrally. He can project psionic blasts and travel to the astral plane, as well as read the minds of various individuals including, but not included to Gamora. His telepathic abilities has allowed him to defeat Drax using a Sync-Time-Warp attack. According to Thanos, the attack had been 100 percent fatal until Drax resisted it, but was incapacitated by it. He has also been able to lobotomize powerful individuals, such as the Fallen One with ease, and recently mind controlled the Hulk. This feat is made more impressive due to the fact that the Hulk has high resistance to telepathic attacks because of his anger. Thanos's mind is also invulnerable to most forms of psychic attacks.

Teleportation
Like other Eternals, Thanos has the natural ability to teleport himself and others, and can also do so through the use of technology. For example, he banished Champion after the latter confronted Thanos about taking his power gem. His use of Tech may be due to the fact that Eternals find the process uncomfortable and it drains their power temporarily. However, given Thanos' power and durability, he may use Tech to teleport out of habit, rather than necessity.

Immortality
When Death resurrect Thanos, he was banished from her dimension. Thus, he became immortal, meaning that he cannot die by any means and has even been shown to regenerate from a skeleton.

However, Thanos seemed to be written below levels shown in The Thanos Imperative. During the Avengers Assemble arc, he opted to have the Hulk fight the Avengers instead of doing it himself. He also was warped against his own wishes by a man made cosmic cube, and afterwards quickly defeated by a large group of Avengers, among which Groot and Captain America were able to hurt him. However, considering his showings against The Annihilators, Ego and The Avengers recently, this could be panned to simply inconsistent writing.

Superhuman Intellect
Thanos was born with superhuman intelligence and has spent much of his life acquiring knowledge. While in the service of Death, he spent a great deal of time gazing into the Infinity Well and learning "secrets" of the galaxy. Aside from the Watchers, he is, perhaps, the most knowledgeable being in the known universe. Thanos' brilliance has allowed him to develop some of most advanced technology in the universe. Silver Surfer himself stated that Thanos' technology would strain Galactus' intellect, who himself had Reed Richards baffled by his Technology. He's erected force fields that Galactus has drained himself in piercing them. They were even able to protect him from Omega, a being stated to be twice as powerful as Galactus. He has also created bombs powerful enough to kill Hunger, a powerful cosmic that threatened the Universe and greatly weaken Galactus.

Thanos has also trained Gamora, helping her to become one of the universe's most feared assassins. While Gamora's training predates meeting Thanos, she has been given numerous upgrades by him, including Class 70 strength and a near indestrutible skeleton. He trained by her to assassinate Adam Warlock, though she didn't complete the task.
