Mutants are soon to become a major focus of the Marvel Cinematic Universe. In addition to Avengers: Doomsday crossing over with 20th Century Fox's X-Men film franchise, the MCU has begun setting the stage for its own iteration of the X-Men. Fans are looking forward to new takes on classic characters like Wolverine and Magneto, but even more exciting is the prospect of certain mutants being adapted for the first time.
Several notable characters from the X-Men comics have never made their way to the big screen. While that is understandable for newer characters, like Egg or Honey Badger, there are also some classic X-Men yet to appear in any live-action films. The MCU has a chance to finally shine the spotlight on these mutant veterans, bringing some of the team's most senior members into the mainstream.
Of all the official X-Men members who have never appeared on the major screen, the oldest is Lorna Dane, better known as Polaris. She is the daughter of Magneto, and she inherited her father's mutant ability to control metal and magnetic fields. Your scores are shown below.
The character with the highest number is your match. Read their description to discover which hero the universe chose for you. Brilliant, driven, and uncompromising in your ambition.
You believe that the right technology — in the right hands — can solve any problem, and you’re confident enough in your own abilities to back that up. Beneath the armor and the bravado, you carry the weight of responsibility deeply. When it truly matters, you’re willing to sacrifice everything.
Principled, courageous, and steadfast. You have an unshakeable sense of right and wrong, and no amount of pressure, politics, or power can make you compromise it. People trust you instinctively — not because you demand it, but because you’ve earned it.
You lead not by authority but by example, and you will always get back up. Strategic, precise, and formidably self-reliant. You don’t need a suit or a superpower — your greatest weapon is your mind and your nerve.
You keep your cards close, trust slowly, and operate three steps ahead of everyone else. Your past is complicated, but you’ve turned it into something that makes you nearly impossible to stop. Powerful, honorable, and ultimately humbled by what truly matters.
You came into your power believing it was your birthright — and then you learned it had to be earned. Your strength is immense, but your greatest growth came from learning to serve rather than reign. Loyal to your people, terrifying to your enemies, and always magnificent.
Quick-witted, deeply compassionate, and driven by a responsibility you didn’t ask for. You’ve learned the hard way that great power comes with great cost — and you show up anyway. You stay grounded when others would ascend, and your humanity is your greatest strength.
You make it look effortless. It never is. Polaris debuted in X-Men #49 from 1968 and joined the team in X-Men #60 the following year.
This made her the first true addition to the original X-Men roster, not counting Mimic, a villain who briefly joined the team, or Changeling, who was retconned to have impersonated Professor X to fake his death. Polaris has been featured in several non-film adaptations, most recently X-Men '97. Her popularity in other media means that she is likely to appear in the MCU, especially because the parenthood angle would set a new version of Magneto apart from Fox's depictions.
In 1975's Giant Size X-Men #1, the original X-Men were captured, and Professor X assembled a new team to rescue them. Most of these mutants -- namely Wolverine, Storm, Colossus, and Nightcrawler -- became some of Marvel's most popular. However, that was not the case for the other two members of the team, Sunfire and Thunderbird.
Sunfire did not actually join the X-Men, returning to his homeland of Japan once the mission was complete, but Thunderbird remained on the roster. Thunderbird, whose real name is John Proudstar, is an Apache man whose mutation grants him superhuman strength and speed, not unlike Beast prior to his blue, hairy transformation. The reason for Thunderbird's lack of popularity is that he passed away in X-Men #95, mere months after his debut, and was not revived until decades later.
The MCU has made a concerted effort to represent Native American characters, like Kahhori and Echo, so it would not be surprising if the films gave Thunderbird a larger role than the comics. Sadie Sink's mysterious character in Spider-Man: Brand New Day has been the source of much speculation, and some have theorized that she will be Rachel Summers, a telepathic hero introduced in the "Days of Future Past" Storyline. She is the daughter of two founding X-Men: Cyclops and Jean Grey.
Rachel was born in the dystopian future of Earth-811, but she eventually traveled to the past of the main Marvel universe and met the X-Men. Jean was presumed dead at the time as a result of "The Dark Phoenix Saga," So starting with 1984's Uncanny X-Men #188, Rachel took her mother's place on the team. Despite the conjecture about Sink, Rachel is unlikely to appear in the MCU, at least any time soon.
A time traveler from an alternate reality would be a needlessly complicated addition to a fledgling X-Men franchise, and Rachel's story would only hold emotional weight if viewers were already attached to the MCU's versions of Cyclops and Jean. On rare occasions, the X-Men have welcomed non-mutants into the fold. Such was the case for Longshot, who debuted in an eponymous self-titled limited series from 1985 and joined the X-Men in Uncanny X-Men Annual #10 the following year.
Longshot is a genetically engineered hero originally hailing from the Mojoverse, a dimension ruled over by the bizarre, television-obsessed tyrant Mojo. Longshot possesses several superpowers, most notably the ability to manipulate luck in his favor, though he can only do so if his intentions are pure. The odds of Longshot appearing in the MCU are directly tied to those of Mojo doing the same.
Unlike Fox's X-Men franchise, the MCU has been willing to explore wacky concepts akin to the Mojoverse. However, there are far more beloved villains whom the MCU will surely prioritize over Mojo, such as Mister Sinister, making Longshot's big-screen debut less probable. Forge technically existed in Fox‘s live-action continuity, as his name was listed on a computer in X2: X-Men United, but he never physically appeared in any of the films.
Introduced in Uncanny X-Men #184 from 1984, Forge's mutant power gives him an inherent understanding of how to build anything. Forge was originally an antagonist to the X-Men, albeit against his will, as Henry Gyrich weaponized his creations to strip mutants of their powers. He was the earliest and longest-lasting of Storm's love interests, though they broke up in Uncanny X-Men #289.
Of all the characters on this list, Forge is the most likely to appear in the MCU. Like Thunderbird, he would bring some Native American representation to the X-Men, but he is far more prominent in the comics than Thunderbird. He has become even more popular in recent years thanks to his role in X-Men '97.
Additionally, Forge's power is unique among the X-Men, which cannot be stated of Polaris, Thunderbird, Rachel, or Longshot.
