Superhuman Strength: Thanos possesses vast superhuman strength the full limits of which aren't known. Death has increased his strength beyond their original limits to levels rivaling or surpassing those of the physically strongest Eternals. Thanos' strength is so vast he has destroyed entire planets with the simple force of his blows. He has proven capable of fighting Thor even when he had the Power Gem.[88] His strength is so vast that he has been able to easily defeat the likes of the Silver Surfer, punch away an attacking Hulk,[47] physically subduing with ease Beta Ray Bill and Ronan the Accuser (as well as casually breaking apart the latter's Universal Weapon)[89] and, most impressively, wrestle with the mighty Tyrant, although only by being additionally empowered by an external power source. Thanos can also augment his strength with his cosmic energy when needed.
Superhuman Speed: Despite his massive muscular bulk, Thanos is capable of running and moving at speeds greater than the finest human athlete.
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, Deathincreased his ability to resist injury to a much greater degree and he is nigh invulnerable. He has withstood at point blank range planet-destroying attacks without any harm. He has withstood blasts from the Silver Surfer 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.[44] He also survived being subjected to an artificial singularity.[90]
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 was formerly banned by Death itself from entering its realm, rendering him truly immortal. No matter the severity of any injury, Thanos was unable to die and completely recovered. This ban has since been lifted.
Accelerated 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 Annihilationevent, Thanos is unable to regenerate missing organs.
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.
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.
Energy Manipulation & Control: 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,[18] infrared heat-beams from his eyes, and disruptor beams, unilaterally striking separate targets with his optic blasts as well as use his mental link to his techno-mystical chair to form vastly powerful energy shields, barriers, and force-fields. The exact extent of Thanos' energy projection abilities are unknown, but his blasts have been capable of rendering the likes of Thor & The Hulk unconscious. He was also able to slightly damage Galactus' armor and blast the Devourer of Worlds off his feet. By collaborating with the In-Betweener they together released the latter from his prison created by Master Order and Lord Chaos.[91] It has been speculated that the nature of Thanos' cosmic energy reserve may be quasi-mystical in nature.
Telepathy: Thanos possesses psionic abilities. His mind is invulnerable to most forms of psychic attack. Thanos has demonstrated the ability to successfully defend himself against psychic assaults from Moondragon and Mantis. He also drove one of the Priests of Pama insane with a gesture, made the Hulk attack his fellow Avengers[36], and forced Conner Sims (the Anti-Man) to destroy his surroundings.[65]
Matter Manipulation & Control: Thanos has demonstrated some ability to manipulate matter on the atomic level, similarly to other Earthborn Eternals. On one occasion, he turned the Skrull, Skragg into stone.
Curse Casting: Thanos seems to be at least partially skilled in magic, evidence being him cursing Deadpool to be unable to die.
Flight: After his fight with Star-Lord wielding the Mandalay Gem, Thanos was shown to fly self-propelled.[92] Whether he recently acquired this ability or if he uses technical equipment for it hasn't been revealed yet.
Teleportation: Thanos can teleport himself across unknown distances through his link with his techno-mystical transport chair. 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.
Abilities
Super-Genius Intelligence: Thanos has a brilliant scientific mind rivaling the best in the Universe.[93]
Skilled Unarmed Combatant: Although he typically avoids physical combat, Thanos is a highly formidable hand to hand combatant. He is particularly skillful at using a combination of his physical and energy manipulative abilities during combat.[94]
Mystical Knowledge: He also has great knowledge of arcane and mystical lore
