Mutants will soon be a big part of the Marvel Cinematic Universe (MCU). Not only will the upcoming Avengers: Doomsday movie connect with the X-Men films from 20th Century Fox, but the MCU is also preparing to introduce its own version of the X-Men. While fans are excited about seeing fresh interpretations of well-known characters like Wolverine and Magneto, they’re especially eager to see some mutants brought to life on screen for the very first time.
Many popular X-Men characters haven’t been featured in movies yet. While it’s not surprising that newer characters like Egg and Honey Badger are missing, some long-standing, classic X-Men haven’t appeared in live-action films either. With the Marvel Cinematic Universe now including mutants, there’s a great opportunity to introduce these veteran characters to a wider audience.
Polaris Was the X-Men’s Earliest Recruit
Lorna Dane, also known as Polaris, is the longest-running X-Men team member never featured in a movie. She gained her powers – the ability to manipulate metal and magnetic fields – from her father.
Polaris first appeared in X-Men #49 in 1968 and officially became a member with issue #60 the next year. This made her the first new hero to join the original X-Men team, excluding Mimic, who was a temporary villain, and Changeling, whose backstory was later changed to reveal he had pretended to be Professor X.
Polaris has appeared in various shows and media beyond movies, most recently in X-Men ’97. Her growing popularity makes it likely she’ll be included in the Marvel Cinematic Universe, and exploring her relationship with Magneto as a parent would offer a fresh take on his character, different from how he was portrayed in previous films.
Thunderbird Debuted Alongside the Most Iconic X-Men
The comic Giant Size X-Men #1, published in 1975, featured a story where the original X-Men were taken prisoner. Professor X then gathered a new group of mutants to save them. While members like Wolverine, Storm, Colossus, and Nightcrawler quickly became fan favorites, the other two – Sunfire and Thunderbird – didn’t achieve the same level of popularity.
Sunfire went back to Japan after finishing the team’s mission, so he didn’t become a permanent member of the X-Men. However, Thunderbird, also known as John Proudstar, stayed with the team. He’s an Apache man with a mutation that gives him incredible strength and speed, similar to what Beast had before he transformed into his furry, blue form.
I’ve always thought it was a shame Thunderbird didn’t get more time to shine! He tragically died so soon after he was introduced in the comics – just a few months after his first appearance in X-Men #95, and he wasn’t brought back for decades. But with the MCU actively working to include more Native American heroes like Kahhori and Echo, I’m really hoping we’ll finally get to see a more substantial version of Thunderbird on the big screen. It feels like the movies could really give him the spotlight he deserved.
Rachel Summers Replaced a Founding Member of the X-Men
There’s been a lot of guessing about her identity, with some fans believing she might be Rachel Summers – a powerful telepath from the famous “Days of Future Past” story arc. Rachel is the daughter of two original X-Men members, Cyclops and Jean Grey.
Rachel Summers originated in a bleak future version of Earth, but she journeyed back in time to the primary Marvel Universe and joined the X-Men. When Jean Grey was believed to be deceased following the events of “The Dark Phoenix Saga,” Rachel stepped in to take her place on the team, beginning with issue #188 of Uncanny X-Men in 1984.
Although there’s been speculation about Sink potentially joining the Marvel Cinematic Universe, it’s doubtful Rachel will appear in it anytime soon. Introducing a time traveler from another reality would make the already developing X-Men franchise overly complex, and her story would only resonate with audiences if they already had a connection to the MCU’s Cyclops and Jean Grey.
Longshot Was the X-Men’s First Non-Mutant Member
Although the X-Men are usually a team of mutants, they’ve occasionally accepted non-mutants as members. Longshot was one of these individuals, first appearing in his own comic series in 1985 before officially joining the X-Men in Uncanny X-Men Annual #10 in 1986.
Longshot is a hero created through genetic engineering who first appeared in the Mojoverse, a reality governed by powerful beings. His main power is manipulating luck to create favorable outcomes – but it only works when he has good intentions.
Longshot’s chances of appearing in the Marvel Cinematic Universe (MCU) depend heavily on whether the character Mojo shows up first. While the MCU hasn’t shied away from unusual ideas like those found in Mojo’s world – something the X-Men films under Fox didn’t often do – there are more well-known villains, like Mister Sinister, that Marvel will likely focus on before bringing Longshot to the big screen. This makes a Longshot appearance less likely at this time.
Forge Became the X-Men’s Main Engineer
Forge was mentioned in the X-Men films – his name appeared on a computer screen in X2: X-Men United – but he never actually showed up on screen. Originally appearing in the Uncanny X-Men comic book in 1984, Forge is a mutant with the unique ability to instinctively understand how to create and construct anything.
I remember when Forge first showed up – it was kind of a bummer because he started out as someone working against the X-Men! It turned out Henry Gyrich was using Forge’s inventions to take away mutant powers, which wasn’t cool. Thankfully, Forge switched sides and eventually became a full-fledged member of the team with issue #255 back in 1989. He actually held that position longer than anyone else did, but things changed and the group dissolved around issue #289.
Out of all these characters, Forge has the best chance of showing up in the Marvel Cinematic Universe. Like Thunderbird, he’d add Native American representation to the X-Men team, but he’s a much bigger character in the comics. His popularity has also been growing recently because of his appearance in X-Men ’97. Plus, Forge has powers that are unlike those of any other X-Man, something you can’t say about Polaris, Thunderbird, Rachel, or Longshot.
