The most powerful mutant in Marvel is Franklin Richards, a reality-warper who has built entire universes, followed by Legion, Proteus and Jamie Braddock. House of X #1 (2019) named 14 Omega-level mutants; Marvel has since added dozens more, including Professor X in 2025. Below, the 15 that matter most, ranked by feats and versatility.
An Omega-level mutant is one whose dominant power has, in Marvel’s own wording, “an undefinable upper limit.” That is a ceiling, not a score, so this ranking weighs what each mutant has actually done on the page and how many problems their power can solve. For where the term came from and the full definition, see our Omega-level mutants explainer; for fighters who are not Omegas, see the strongest X-Men ranked.

1. Franklin Richards
Franklin Richards is a reality-warper who can create, reshape and restore entire universes. As a child he spun a pocket universe into existence during Heroes Reborn (1996), and his power helped rebuild the multiverse after Secret Wars (2015).
He was on the original House of X #1 list as Powerhouse. Fantastic Four (2020) #26 then ruled that he was not a true mutant, and a 2024 Fantastic Four story reopened the question by revealing he had been repressing his powers. Mutant or not, nothing else on this list operates at his scale. Full record: Franklin Richards in the Codex.
2. Legion (David Haller)
Legion is a power-manifestation Omega whose hundreds of personalities each carry a different ability, from telepathy to time travel. Charles Xavier’s son rewrote Marvel history in Legion Quest (1995), when his attempt to kill Magneto in the past killed his own father instead and created the Age of Apocalypse.
His ceiling is effectively unlimited; his control is not. That instability is the only reason he ranks below Franklin.
3. Proteus (Kevin MacTaggert)
Proteus is a psionic reality-warper who reshapes matter and perception around him, limited only by the host bodies he burns through. Moira MacTaggert’s son nearly broke the classic X-Men in his 1979 debut arc, and he was stopped only because metal disrupts his energy form.
That weakness is the only thing keeping him out of the top two. A Proteus with a host that does not burn out would be a planet-level problem.
4. Monarch (Jamie Braddock)
Jamie Braddock sees reality as strings he can pull, rewriting people, probability and physical law. The brother of Betsy and Brian Braddock took the name Monarch on Krakoa in Excalibur (2019) #1.
His power is arguably on Proteus’s level. What drops him to fourth is a long record of madness and manipulation by others, which means he rarely brings that power to bear with a clear goal.
5. Jean Grey
Jean Grey is Marvel’s benchmark Omega-level telepath, able to read, rewrite or shut down minds on a global scale. The rating attaches to her telepathy specifically; her telekinesis is elite but not Omega, and the Phoenix Force is a separate cosmic entity she hosts.
Strip the Phoenix away and she still ranks fifth, because unlimited telepathy wins most fights before they start. More: Jean Grey’s sourced feats and our Phoenix Force guide.
6. Hope Summers
Hope Summers is an Omega-level power manipulator who can copy, amplify and redirect the abilities of mutants near her. The “Mutant Messiah” born in Messiah Complex (2007) became the engine of Krakoa’s resurrection protocols, boosting the other members of the Five so they could rebuild dead mutants.
Her power borrows from whoever is in range, so her ceiling is set by her surroundings. Next to Omegas, it is enormous.
7. Mister M (Absolon Mercator)
Mister M manipulates matter at the subatomic level, rearranging objects, bodies and his own form at will. Introduced in the Mutant Town series District X, he is the least-used name on the 2019 chart.
That is a writing problem, not a power problem: matter manipulation without a stated limit is a reality-warper in all but name.
8. Vulcan (Gabriel Summers)
Vulcan absorbs and projects almost any form of energy, which makes him one of the few Omegas who can win a straight slugfest. The third Summers brother seized the Shi’ar throne in The Rise and Fall of the Shi’ar Empire (2006–07).
He is raw output with little finesse, which is exactly why the versatility test below puts him mid-table.
9. Magneto
Magneto controls magnetism on a planetary scale, bending metal, electromagnetic fields and the Earth’s own magnetic field. His most infamous feat is tearing the adamantium from Wolverine’s skeleton in X-Men #25 (1993).
Magnetism touches almost everything, which makes him the most battle-tested Omega on the list. See his Codex record and the magnetism power page.
10. Storm
Storm is an Omega-level weather manipulator who can control atmospheric conditions across an entire planet. She was on the original 2019 list, ending years of fan debate about her rating.
She also supplied this ranking’s logic. In X-Men: Red #16 she told the Arakkii warlord War that fights between Omegas are “all about versatility,” and weather gives her lightning, cold, wind and pressure in one package. Her lightning also earns her a spot among the best electricity superheroes. Codex: Storm.
11. Professor X
Professor X is the newest household-name Omega: X-Men vol. 7 #13 (March 2025) formally rates his telepathy at that level. He was conspicuously absent from the 2019 chart, which appeared in his own files.
The upgrade is covered in detail by Screen Rant. It ranks him below Jean because two Omega telepaths are equal on paper, and Jean’s feats are bigger.
12. Iceman
Iceman is an Omega-level cryokinetic who can freeze moisture across vast areas and rebuild his body from ice. Xavier’s notes called his potential Omega in X-Men Forever #3 (2001), long before most writers used it.
Few Omegas gained more from the label; it recast decades of jokey appearances as underuse. See cryokinesis in the Codex.
13. Exodus
Exodus is an Omega-level telekinetic and a powerful telepath who can heal and restructure bodies through psionic force. The ancient mutant who once worshipped Magneto as a messiah later sat on Krakoa’s Quiet Council.
14. Elixir (Josh Foley)
Elixir is an Omega-level biokinetic who can heal, rewrite or destroy living tissue with a touch. He was one of the Five behind Krakoa’s resurrections, which made him one of the most important mutants on the island.
His power is narrow, and that is what drops him this low on a versatility ranking.
15. Kid Omega (Quentin Quire)
Kid Omega is an Omega-level telepath whose raw psychic output rivals Jean Grey’s while his control usually doesn’t. He debuted in New X-Men #134 (2003) and took the name in #135.
Omega-Level Mutants Added Since 2019
The 2019 chart was a starting point. According to the running record on Wikipedia, Marvel has designated these Omegas since:
- Genesis and the Arakkii Omegas (X-Men vol. 5 #16, 2020; X-Men Red vol. 2, 2022–23): the mutants of Arakko, including Isca the Unbeaten, whose Omega power is that she cannot lose.
- The Four Horsemen (Death, Famine, Pestilence and War; X-Men Red vol. 2 #16, 2023).
- Forge (X-Force vol. 7 #1, 2024): Omega-level technopathy, but only while using a machine he built.
- Maggott (Storm vol. 5 #6, March 2025): Omega-level psychometry granted by Eternity, not born with.
None of them makes our top 15 yet, because most have a few years of feats rather than decades.
Omega-Level Mutants in 2025–2026: What Changed
- March 2025: Professor X and Maggott are designated Omega-level in X-Men #13 and Storm #6.
- October–December 2025: Age of Revelation jumps ten years ahead to a future where Magneto is dead and Quentin Quire runs a spy network of Omega Kids. It is a possible future, not current continuity.
- February 2026: Storm headlines Storm: Earth’s Mightiest Mutant.
- July–August 2026: X-Men ’97 season 2 aired on Disney+.
- December 18, 2026: Avengers: Doomsday brings back Ian McKellen’s Magneto and Patrick Stewart’s Professor X.
Who Isn’t Omega-Level (and Why)
Wolverine, Cable, Apocalypse, Emma Frost, Rachel Summers and Nate Grey are all hugely powerful, and none of them appears on any of Marvel’s Omega designations. Wolverine’s healing has documented limits. Rachel is the strangest omission, since Nimrod called her “Class Omega” back in Uncanny X-Men #208 (1986), the first use of the idea.
Why a Versatility Ranking Beats a Power Score
Most lists sort Omegas “weakest to strongest” as if the label were a number. Marvel defined it as an uncapped ceiling, so every mutant here is limitless at one thing. Comparing Iceman’s cold with Magneto’s magnetism is like asking whether infinity is bigger in miles or kilograms.
What actually separates them is how many problems a power solves, which is the test Storm named. It reshuffles the board: the reality-warpers sit on top because they change the rules instead of winning inside them; Hope outranks Vulcan because she borrows everyone’s power; Elixir falls because healing is one tool. For a broader board that includes non-mutants, see our most powerful comic book characters.
Collector’s Corner: Key Omega-Level First Appearances

- Uncanny X-Men #125 (1979): first full Proteus, an affordable Bronze Age key.
- New Mutants #25–26 (1985): Legion’s cameo and full debut; buy the pair.
- House of X #1 (2019): not a first appearance, but the issue that made Omega-level canon.
Frequently Asked Questions
Who is the most powerful mutant in Marvel?
Franklin Richards, a reality-warper who has created pocket universes, is usually ranked first, though his mutant status has been disputed since 2020. Among undisputed mutants, Legion, Proteus and Jamie Braddock top the list because they can rewrite reality.
How many Omega-level mutants are there?
House of X #1 (2019) listed 14. Marvel has since added dozens, including Genesis and the Arakkii Omegas, the Four Horsemen, Forge, Professor X and Maggott, and has not published a single updated count.
Is Professor X an Omega-level mutant?
Yes. X-Men vol. 7 #13 (March 2025) formally designated Charles Xavier an Omega-level telepath. He was not on the original 2019 list.
Is Storm an Omega-level mutant?
Yes. Storm was on the original House of X #1 list in 2019 for weather manipulation.
Is Wolverine an Omega-level mutant?
No. Wolverine’s healing factor has documented limits, and he has never appeared on any of Marvel’s Omega designations.
Is Franklin Richards still a mutant?
It is disputed. Fantastic Four #26 (2020) said he was not a true mutant, but a 2024 Fantastic Four story revealed he had been repressing his powers and reopened the question.
