The 10 Most Powerful Versions of Thanos, Ranked

Thanos is best known for his use of the Infinity Gauntlet, but strip that away, and he is still a Titan who has five decades of comic book history. On top of the Infinity Gauntlet, he has wielded the Cosmic Cube, the Heart of the Universe, and a device that lets him kill the very being who created the Multiverse. Debuting in Iron Man Vol. 1 #55 (1973) by Jim Starlin and Mike Friedrich, Thanos is not a villain who has one basic power level, and across continuities and storylines, he has wielded wildly different power sources. While everyone knows about the Infinity Gauntlet and Cosmic Cube, other deep cuts like the Astral Regulator and the Cancerverse show how terrifying Thanos can be.

From his most famous moment, where he wiped out half of the universe, to the non-canon moments like The End, here are the most powerful versions of Thanos, ranked.

10) Cosmic Cube Thanos

This version of Thanos appeared the year after his debut in a storyline told in Captain Marvel #25-34 (1973-1974) by Mike Friedrich and Jim Starlin. This is Thanos’s first major bid for universal domination, where he seeks out the Cosmic Cube, a reality-altering device that grants him unlimited power to reshape reality and impose his will. Using the Cosmic Cube, Thanos abducts and overpowers Captain Marvel, Iron Man, Drax the Destroyer, and Moondragon, and he reshapes events to his will. However, his power here is all dependent on using the Cube, and when Captain Marvel destroys it, Thanos loses that power and is easily defeated.

9) Ultimate Thanos

This Thanos is the one from the Ultimate Marvel Universe, and he debuted in Ultimate Fantastic Four #35 (2006) by Mike Carey and Pasqual Ferry. The Ultimate version differs from mainline Thanos because he doesn’t care about the Infinity Gems and instead wants to use the Cosmic Cubes to rule the universe outright, and not as a means to attract Death. Thanos uses the ancient Cosmic Cube to conquer countless worlds, and he rules the empire called the Endless Resurgence. He doesn’t age, can resurrect himself by killing others, and becomes more powerful the longer he remains dead. He is a god-tier conqueror, but once again, he relies solely on the Cosmic Cube.

8) Annihilation Thanos

This is the Thanos who appeared in the “Annihilation” (2006-2007) crossover event. The main villain here was Annihilus, who invades the positive-matter universe, and Thanos allies himself with the villain, offering up his scientific genius to the Annihilation Wave’s attacks. With Thanos’s help, the Wave captures Galactus and Silver Surfer. Thanos engineers the machinery that turns Galactus into a living weapon, siphoning his world-devouring power to threaten the entire multiverse. Thanos finally starts to turn on Annihilus by freeing Moondragon, but Drax the Destroyer shows up and kills Thanos, ending his time in the series and fulfilling his purpose in life.

7) Infinity Crusade Thanos

The Infinity Crusade (1993) by Jim Starlin and Ron Lim is the third part of the Infinity trilogy, and here, Thanos works with the heroes. The Goddess gathers thirty Cosmic Cubes into a wish-granting Cosmic Egg and brainwashes Earth’s heroes. The Goddess targets Thanos as her first threat, but Adam Warlock saves him, and they form an uneasy alliance. Here, Thanos shows his genius as a strategist who helps Warlock and Mephisto bring down the near-omnipotent villain. This is a rare chance for Thanos to show how powerful he is without a major power source, as his tactical brilliance against omnipotence-tier power proves his might.

6) Thanos Imperative

The Thanos Imperative (2010) by Dan Abnett and Andy Lanning is set in the Cancerverse, a parallel reality where Death has been banished. As a result, life runs rampant like a cancer, bleeding into the main universe through the Fault. Thanos is the key here because he is the avatar of Death itself, the one weapon the deathless Cancerverse cannot survive contact with. Lord Mar-Vell is the Cancerverse’s avatar of Life, and when they face off, Thanos surrenders before unleashing Death, which claims Mar-Vell and collapses the Cancerverse. As the literal embodiment of Death, he has reality-ending powers, but it is all conceptual and not as deadly as other versions of Thanos.

5) Thanos Quest

The Thanos Quest (1990) is a two-issue miniseries by Jim Starlin and Ron Lim that is the direct prelude to The Infinity Gauntlet. Death resurrects Thanos to cull half the universe, and this is when he learns about the true nature of the six Infinity Gems. With Death’s blessing, Thanos hunts down each Gem from the cosmic entities who hold them, outwitting and overpowering beings far older and stronger than himself. Thanos defeats and strips the Gems from the Elders of the Universe and exploits the concept-being known as the In-Betweener at the Nexus of Reality. Without the Infinity Gauntlet, Thanos is at his cleverest and most strategic here and defeats beings much more powerful than him to prepare for one of his greatest accomplishments.

4) Infinity Gauntlet Thanos

The most famous version of Thanos is the one from the Infinity Gauntlet crossover event. In this story by Jim Starlin, George Pérez, and Ron Lim, Thanos gathers all six Infinity Gems, places them in a single Infinity Gauntlet, and then gains control over time, space, mind, soul, power, and reality. It is here that Thanos achieves omnipotence. Because he wants to court Mistress Death, Thanos snaps his finger and erases half of all life in the universe, including many of Earth’s heroes. He humbles most of the surviving heroes, including Adam Warlock and the Silver Surfer. However, what holds him down here when it comes to his overall power levels is that his ego is his undoing, losing the Gauntlet to Nebula and then Adam Warlock.

3) King Thanos

Thanos Vol. 2 #13-18 (2017-2018) by Donny Cates and Geoff Shaw introduces the far-future King Thanos in the “Thanos Wins” storyline. This story sees present-day Thanos dragged into a future where he has already won, but now rules over a dead, conquered universe ruled from a compound built from the bones of a fallen Celestial. King Thanos has murdered nearly all life in the cosmos and holds the Twilight Sword in a universe he emptied. This version of Thanos kills Galactus and turns Cosmic Ghost Rider into a servant. He keeps a savage Hulk chained up like a pet and then kills the Silver Surfer. This is the Thanos who enjoys the ultimate victory.

2) Marvel Universe: The End Thanos

Marvel Universe: The End (2003) is a six-issue miniseries by Jim Starlin and Al Milgrom, and the device that Thanos uses here is the Heart of the Universe. This is an energy source from which the entire cosmos is built. Absorbing it makes Thanos one with everyone and everything, explicitly more powerful than he ever was with the Infinity Gauntlet. With the Heart of the Universe, Thanos kills Celestials and other cosmic gods and overpowers the assembled cosmic beings, including the Living Tribunal. He absorbs the entire multiverse until nothing remains. He then chooses to act as savior rather than destroyer, uses the Heart to heal space and time, and remakes the universe from the ashes. It is one of the most powerful versions of Thanos ever depicted in Marvel Comics, thanks to Thanos reshaping reality.

1) Thanos With the Astral Regulator

The Astral Regulators are devices created by the One-Above-All to keep the infinite realities of the Multiverse from colliding. Contact with one normally means instant extinction for any being. However, because Thanos had died and been resurrected countless times, he is a being who can’t ever really die, meaning he can hold the Regulator without instant extinction. In Thanos: The Infinity Siblings, Thanos: The Infinity Conflict, and Thanos: The Infinity Ending (2018-2019) by Jim Starlin and Alan Davis, Thanos confronts and absorbs the Living Tribunal and even the One-Above-All. This was Thanos’s greatest victory. Thanos only fell here when he died by suicide to free all beings, and since he beat the One-Above-All, there is no other version of Thanos more powerful.
