Omega. Omega is the most powerful type of Thanosi clone. He had powers similar to both Thanos and Galactus, and allegedly his abilities surpassed those of Galactus as well.
Omega, a clone of Thanos that incorporates the power and genetics of Galactus, easily ranks among the most powerful Thanos variants in the multiverse and the most crucial cosmic beings in the Marvel Universe.
1 Thanos / Darkseid
The duo actually seem made to contrast with one another. Thanos is fixated on death and uses the Infinity Gauntlet to spread it across the universe. Darkseid wants to control all life and searches for the fabled Anti-Life Equation to do so.
Kang is more powerful than Thanos
Thanos certainly presented the Avengers with a challenge, and his power continued to grow as he amassed the various infinity stones. Kang, though, seems to have almost limitless power once he can access even one aspect of his hyperadvanced technology.
An alternate version of Thanos appears in the limited series Marvel Zombies 2, set in the alternate universe of Earth-2149. Having been "zombified" and recruited into the cosmically powered Galacti, the character is killed by a cosmic-powered Hulk after an altercation over food.
One Above All was one of the many victims of Thanos in his eternal quest to please Death. He was obliterated along his fellow Celestials by Thanos when he stabbed Black Bolt to death in order to use his destructive voice as weapon.
King Thanos is an alternate-reality variant of Thanos from the Thanos solo run & Cosmic Ghost Rider storylines of Marvel Comics. He is a Thanos who defeated the Avengers and who is near victory in his genocidal quest.
Ant-Man and The Wasp: Quantumania director Peyton Reed hints at Jonathan Majors' Kang the Conqueror as a bigger villain than Thanos.
1 Galactus
Marvel has many powerful immortals, but few can match Galactus. The World Devourer controls the full might of the Power Cosmic, which gives him near complete control of energy and matter.
Drax The Destroyer
While there are many Marvel villains that love and adore Thanos, there are some heroes in the universe that simply despise him. One such hero, who very much hates Thanos and seems to survive for the sole purpose of being able to kill him, is Drax, the Destroyer.
The Asgardian Son of Odin was extremely close to ending Thanos at the end of Avengers: Infinity War. After gaining the powerful weapon Stormbreaker, Thor becomes the wielder of the most powerful weapon in the universe. Stormbreaker is capable of killing Thanos outright, and only Thor is currently worthy of wielding it.
Odin would win in a fight against Thanos. Odin overpowers Thanos at almost every turn. He is more intelligent, durable, and faster, and his centuries of warfare led to more advanced combat skills.
Hela, the Asgardian Goddess of Death, rules two of the nine realms: Hel, land of the dead, and Niffleheim, land of eternal ice. With a simple touch, she can cause gods to perish, but Hela's purpose is to receive Asgardian souls, as well as their followers.
Omnipotent(ial) Thanos is immensely strong and resistant to injury, invulnerable to nearly all types of poison, disease, and telepathic attack. He also has incredible psychic abilities; he can sense things several star systems away.
The most powerful Thor variant is Ultimate Thor, who's real name is Thorlief Golmen. Golmen discovers he is the most recent reincarnation of Thor Odinson and begins his journey as the new God of Thunder. This version of Thor was less reliant on Mjolnir as a power source.
1) Thor. Thor, one of the most powerful Avengers in the MCU, is known for his incredible strength, lightning powers, and indestructible hammer Mjolnir. He is a formidable opponent, and in Avengers: Endgame, he wields Stormbreaker, a weapon that is even more powerful than Mjolnir.
1. Thanos (Avengers: Infinity War, Avengers: Endgame)
Galactus was killed by Thor during the "Herald of Thunder" story arc in Thor (vol. 6) #1–6 (March 2020 – August 2020), and reappeared after a two-year hiatus in Fantastic Four (vol. 6) #45 (July 2022) — the final issue of the event "Reckoning War" — where Galactus is resurrected by his former heralds.
Thanos. Perhaps the Avengers villain that MCU fans are most familiar with, Thanos's motivations in the comics are slightly different, but his power remains a constant. He's a true force to be reckoned with, and one that inspires a legion of his own that also has to be contended with.
Instead of aliens, androids, and wizards, Thanos is afraid of aliens, Asgardians, and wizards. The theory posits Ego, Odin, and The Ancient One as three of Thanos' greatest fears, and he waited until all of them were dead to make his move.
Thanos has long been aware of the immense power and strength of Hulk, which is why he has a fear of the Avenger. The only time Thanos has faced off against the Hulk in a one-on-one physical fight was in the comics, and it did not end well for him.
Kang has arrived. At Comic-Con 2022, Marvel Studios' Kevin Feige made official what many fans had been theorizing for some time: Kang the Conqueror is the MCU's next Thanos-like villain.
Being surprised with Nebula's trust in what he had said, Thanos thanked her for believing him and finally admitted that perhaps he had treated her too harshly. Before he could say anything else, an enraged Thor decapitated Thanos, killing the Mad Titan.
In 2014, Nebula and Gamora, under orders from Thanos, are dispatched to assist Ronan the Accuser in obtaining the Power Stone. After learning Gamora has it, Nebula goes to Knowhere and shoots her pod down and takes the Stone for Ronan, who then betrays Thanos, intending to destroy the planet Xandar and kill Thanos.
In the mini-series event "Judgment Day", where the Eternals went to war with the mutants of Krakoa, Starfox refers to himself as a "mutant". His brother, Thanos, was always referred to as a mutant of the Titan Eternals.
