The X-Men movies have featured many mutant heroes over the years. But these X-Men have had their reputations ruined by Fox Studios. They will never get a solo movie.
Jubilee is a mutant hero that debuted way back in 1989. Her status as an X-Men member divided fans. Half of the fans liked Jubilee as a character. The other half hated it. Nevertheless, Jubilee has remained a popular Marvel hero. She was nothing more than a redundant extra in the first three X-Men films. In X-Men: Apocalypse, Jubilee became the tour guide for new Xavier Institute students. Her character has gone through a lot. From a valley teen to a vampire mom, there’s a lot the X-Men movies could have explored. Sadly her on-screen reputation stands ruined.
There were indeed rumors that Fox is planning a Sabretooth solo film after X-Men origins: Wolverine. Even someone as talented as Liev Schreiber could not bring him to the frontlines. Sabretooth’s legendary rivalry with Wolverine is the stuff history books are made out of. It is so sad to see such a wonderful character go to waste. Both movie iterations of Sabretooth, be it Tyler Mane or Liev Schreiber, failed to capture to raw savagery of the original Victor Creed.
For ardent X-Men fans, no X-Men character from the movies screams a louder ‘missed opportunity’ than Psylocke. This fan-favorite psionic ninja warrior is the sister of Captain Britain and a crucial member of the X-Men. And she was botched twice in the movies. Psylocke first appeared as an extra in X-Men: The Last Stand. She was a member of the Omegas, a group that was killed by Jean Grey. In X-Men: Apocalypse, Olivia Munn played the character to absolute imperfection.
Robert da Costa is a Brazilian mutant with the ability to absorb solar radiation. The guy first appeared as a member of the New Mutants team. Sunspot has since become incredibly popular. In X-Men: Days Of Future Past, da Costa participated in the initial fight against the Sentinels in the dark future timeline. In New Mutants, Sunspot failed to make a major impact and will soon be pushed into the annals of obscurity in the comic book film industry.
As far as mutant heroes are concerned, Warpath is a total badass. He is the Chuck Norris of the X-Men. The dude has a host of abilities at his disposal. Serving as the X-Men’s tracker, he was the one who realized the Sentinels are at the gates in Days of Future Past. He tried keeping the Sentinels at bay but the Sentinels melted off his face. His death was quite unceremonious. And the way the character was treated has squashed all hopes for a solo movie.
Jamie Madrox aka the Multiple Man has the uncanny mutant ability to create clones of himself. Despite what X-Men: The Last Stand showed us, he is not actually a bad guy. The movie shows that Multiple Man was caught robbing multiple banks at the same time. In the comics, Madrox has helped the X-Men on numerous occasions and even went on to found X-Factor Investigations, his very own detective agency. The movie version of Madrox was a smug and arrogant con-man and was nowhere near the mutant hero that enjoys a cult-like following within comic book fan circles.
His mutant ability is spontaneous evolution. You can put Darwin into a vat of molten steel or in the Mariana Trench. His body will adapt itself by changing its biology that can withstand any drastic change in its immediate environment. His ability is that Darwin can literally survive anything. In X-Men: First Class, Darwin was given so little screen time that it was downright criminal. And the way they had him killed was an affront to the very legacy of his character as well as the X-Men.
