Omega-level mutants possess uniquely powerful abilities, and Marvel has already introduced many such characters in various X-Men movies and TV shows.

Over multiple adaptations and continuities, various X-Men movies and TV shows have introduced Omega-level mutants. The mutant heroes and villains featured in the X-Men comics rank as some of Marvel’s most powerful characters. However, even among Marvel’s mutants, there are hierarchies of power, with the strength of mutants’ abilities ranked to indicate their status among their kind. The likes of Fox’s X-Men movies and multiple TV shows have introduced many such powerful characters.

The most powerful mutants are defined by their Omega-level powers. This status reflects the immeasurable strength of the character in question’s ability, meaning that their power levels cannot be surpassed in any measurable way, effectively rendering them as more powerful than any other character in one specific regard. Though the Marvel TV shows and movies featuring the X-Men don’t often delve into explanations of mutants’ power rankings, the on-screen adaptations have featured multiple Omega-level characters. With that in mind, here are all 11 Omega-level mutants who have appeared in Marvel’s X-Men movies and TV shows.

11. Ororo Munroe/Storm

Appeared in: Various

One of the most prominent Omega-level mutants featured in X-Men media, Storm is considered the most powerful character of her kind. Her ability to control the weather is unmatched within the X-Men universe, with no other mutants able to compete in terms of power. Storm’s various powers have been shown to influence the weather on other planets, and indirectly grant her a host of secondary abilities.

Storm has been featured in many X-Men movies and TV shows, including as a main character in X-Men: The Animated Series in the ‘90s and as part of X-Men ‘97’s cast. Storm appeared in Fox’s X-Men movies, played by Halle Berry in multiple movies, and Alexandra Shipp in X-Men: Apocalypse and Dark Phoenix. As a prominent member of the X-Men, Storm is one of the Omega-level mutants often featured in adaptations of the iconic Marvel heroes.

10. David Haller/Legion

Appeared in: Legion

David Haller is a complex figure within the X-Men universe. Best known as Legion, he possesses the ability to alter time and reality on a cosmic scale at will. Haller also has dissociative identity disorder, and his powers manifest in different ways depending on which alter is currently the dominant part of his personality. Legion is an Omega-level mutant, as his reality-warping abilities are immeasurably powerful compared with other similar characters in the Marvel universe.

Legion has most prominently featured in the TV show Legion, which aired for three seasons between 2017 and 2019. David Haller was brought to life by Dan Stevens, and the show explored his status as the son of Charles Xavier and the difficulties of living with such powerful abilities alongside a mental illness. Designed specifically to stand alone from other cinematic continuities, Legion ambitiously explored the complex and remarkable story of one of Marvel’s most powerful Omega-level mutants.

9. Rachel Summers/Askani

Appeared in: X-Men: The Animated Series – “Beyond Good and Evil, Part 4”

As the child of two of the most iconic members of the X-Men, Rachel Summers’ status as a particularly powerful figure within the Marvel universe is an interesting one. The daughter of Jean Grey and Scott Summers from the dystopian future of Days of Future Past, Rachel Summers, also known as Askani, possesses an array of psionic abilities including telepathy, telekinesis, psychometry, and chronoskimming.

Rachel was briefly featured in X-Men: The Animated Series, despite an incredibly limited role. Though she was clearly depicted within the TV show, her role as an Omega-level mutant is often debated. She’s technically unconfirmed as one in the comics, although it has also been explained that there is no upper limit to her power, which ultimately should qualify her as Omega-level. Despite her hugely powerful potential, Rachel Summers has only been briefly featured in wider X-Men media outside of the comics.

8. Bobby Drake/Iceman

Appeared in: Various

Historically speaking, Bobby Drake – better known as Iceman – is one of the most consistent members of the X-Men. The founding member of the team possesses the ability to manipulate ice and cold by freezing the water vapor around him. This allows Drake to use ice in almost any conceivable way, including covering his body in it and using it as a suit of armor. Iceman has been confirmed as one of Marvel’s Omega-level mutants, as there is no measurable way for any other character to surpass his ice-manipulation abilities.

Iceman appeared in multiple X-Men movies, starting with 2000’s X-Men, played by Shawn Ashmore. A younger version of the hero, the film presented him as a junior X-Man to the likes of Cyclops, Storm, and Jean Grey. Iceman has also been featured in multiple animated X-Men shows.

7. Kevin MacTaggert/Proteus

Appeared in: X-Men: The Animated Series

Kevin MacTaggert, also known as Proteus, is an Omega-level mutant and the son of Scottish genetic researcher Moira MacTaggert. Proteus’ psionic powers allow him to manipulate and alter reality, and mean that he exists in a state of pure psionic energy. This allows him to take possession of other people’s bodies, which in turn grants him access to their memories. The versatile nature of Proteus’ abilities make him a uniquely powerful mutant in the context of Marvel’s pantheon.

Proteus was featured in X-Men: The Animated Series, which adapted his origin story from The Uncanny X-Men. His appearance incorporated many of the key elements of the character, including the impressively powerful nature of his abilities. The version introduced in The Animated Series featured slightly revised powers, including the ability to take human form at will, although his Omega-level powers remained intact.

6. Gabriel Summers/Vulcan

Appeared in: X-Men ’97

Gabriel Summers, the third of the Summers brothers revealed in the X-Men comics, is better known under the moniker Vulcan. Vulcan’s energy absorption and manipulation abilities are essentially unparalleled within the Marvel universe, and he has been named as an Omega-level mutant as a result. As well as all traditional forms of energy, Vulcan has also been shown to be capable of manipulating other more exotic types, such as his brother Cyclops’ blasts.

The Omega-level mutant Vulcan appears in X-Men ’97 as part of the Shi’ar Imperium. Though the show has not explored the true extent of Vulcan’s abilities, the depiction is in line with his comic book appearance. His connection to other powerful figures within Marvel’s catalog of X-Men characters further cements his reputation as a dangerous Omega-level mutant, particularly as he has been known to act against the X-Men and the people of Earth.

5. Hope Summers

Appeared in: Deadpool 2

Hope Summers is undeniably one of the most important mutants in the Marvel universe. As the first mutant born after M-Day, Hope stands out even among her own kind. Her ability to psychically manipulate and mimic the powers of other mutants at their highest capacity makes her perhaps the most versatile figure in the X-Men mythos. With no upper limit to her powers established, Hope Summers is one of Marvel’s most prominent Omega-level mutants, and is considered by many characters to be the mutant messiah.

Though she may seem an unlikely addition to Deadpool 2’s cast, Hope Summers made an incredibly brief cameo in the X-Men movie. Shown in Cable’s flashback as the daughter murdered by Firefist in one potential future, Hope’s powers were not demonstrated in the movie. However fleeting her appearance may be, she’s still another Omega-level mutant to have appeared in an X-Men movie.

4. Erik Lensherr/Magneto

Appeared in: Various

Magneto is undoubtedly one of the most iconic and complex characters in the history of the X-Men comics. Most commonly depicted as a villain, Magneto’s complicated motivations and layered characterization make him one of Marvel’s most fascinating figures. His ability to create and manipulate magnetic fields have been shown on many occasions to be extremely powerful, and with no clear limit to his power, Magneto is another character defined as an Omega-level mutant.

Magneto has been featured in some way in practically every major X-Men movie or TV show. He’s typically written as a villain, such as in X-Men: The Animated Series or Fox’s initial X-Men trilogy, although other depictions, such as Michael Fassbender’s portrayal of the character in the prequel movies, are left more morally ambiguous. His prominent role in multiple X-Men stories means that Magneto is heavily featured in various adaptations of the comics.

3. Stryfe

Appeared in: X-Men: The Animated Series – “Beyond Good and Evil, Part 4”

Stryfe’s backstory is one of X-Men’s more complicated, and his status as an Omega-level mutant is also a complex issue. A clone of Cable, Stryfe possesses the original telekinetic and telepathic abilities of the original Nathan Summers, although without the additional complications of the techno-organic virus Cable was infected with as a child, Stryfe’s powers are seemingly at the Omega-level confirmed to have been Cable’s original capability. Alongside Nathan Summers’ natural mutant powers, Stryfe possesses multiple abilities as the result of genetic experimentation and augmentation, only furthering his status as a powerful villain.

Stryfe was briefly featured in X-Men: The Animated Series alongside Apocalypse. Though Cable has been featured more prominently, he has never possessed the Omega-level abilities that he’s capable of in any adaptation. Stryfe’s power levels are not explored in The Animated Series, and so he is presumably at his standard level.

2. Jean Grey/Marvel Girl

Appeared in: Various

Jean Grey is perhaps the most obvious example of an Omega-level mutant in the history of the X-Men. Her powerful psionic abilities grant her telekinesis and telepathy, which have been noted on multiple occasions to be Omega-level abilities. Her status as the physical embodiment of the Phoenix Force only adds to her aura of untapped power, but it’s the indefinable upper limit of her original abilities that qualify Jean Grey to be categorized as an Omega-level mutant.

Jean Grey has been featured in an array of X-Men adaptations in both movies and TV shows. As a main character of both X-Men: The Animated Series and X-Men ’97, Jean’s story was explored in depth. Played by Famke Janssen in Fox’s original X-Men movies and Sophie Turner in the prequel movies, the Omega-level telepath and telekinetic is one of the best-represented characters in the history of the X-Men.

1. Franklin Richards/Powerhouse

Appeared in: X2 (Easter Egg), with an indirect mention in Doctor Strange in the Multiverse of Madness

Though Franklin Richards has been retconned as a human mutate, he was originally written as a mutant with Omega-level abilities. The son of Mister Fantastic and the Invisible Woman possesses reality-warping powers on par with Marvel’s most powerful beings. While he hasn’t been directly featured in X-Men movies or TV shows, he was indirectly mentioned in Doctor Strange in the Multiverse of Madness, as Reed Richards references his children, and is also hinted at in an Easter egg in X2 that shows his name on a list of mutants.

Other Omega-level mutants have been hinted at in X-Men movies. Kid Omega was credited as appearing in X-Men: The Last Stand, but this was later revealed as a typo, and the character in question was, in fact, the mutant Quill. A mutant scavenger appearing in X-Men: Days of Future Past also closely resembles Nate Grey, though he has never been officially identified as such. As some of the most powerful characters in the history of the X-Men, Omega-level mutants often play vital roles in Marvel’s adaptations, so it makes sense that only a limited number have appeared so far.
