Marvel Comics, unlike the MCU, does not have any limitations as to which hero can be showcased and which hero cannot. To that end, Marvel has used its entire hero roster up to maximum use. One hero who is part of one team can easily become a part of another major superhero team. The Avengers have also given memberships to heroes from yet another prominent superhero team from Marvel Comics. And you won’t ever be able to guess which heroes we are talking about. Presenting – 15 Popular X-Men heroes who Fans never knew have been Avengers!!!
Storm has been a part of the X-Men since Avengers vs. The X-Men of 2012. But she has been a part of the Avengers as well. In 2006’s Marvel Adventures: The Avengers #1, Storm becomes an official member of the Avengers squadron. In 2011, Storm aka Ororo Munroe became a part of the Avengers again in Avengers #19 and fought Norman Osborn.
Avengers vs. The X-Men issues left a lot of bad blood between two of Marvel Comics’ greatest superhero teams. Rogue was chosen to be a member of the Avengers Unity Squad, a group formed after the events of the storyline to help the X-Men and the Avengers come back together. Rogue was one of its longest standing members. That membership came to a screeching halt only this year in 2018.
X-23 has now officially embraced her rightful legacy as the heiress to the clawed demon that is Wolverine. But in the 2000’s, she was a freaking hot mess of a mutant hero. She was put up along with other trainees in the X-Men, where they were trained to hone their skills and tame their powers. After that, she was also selected to become a part of the Avengers trainee squadron of young superheroes. X-23 has always been an Avenger and an X-Man in her core and she reflects the ideals of the Avengers and the Honour of the X-Men whenever she graces the comic book pages.
The Summers brothers are all very powerful. Cyclops and Vulcan are masters at strategy, tactics and energy manipulation. And so is Havok. But he has always failed to get out of his big brother’s shadow that almost always got the lion’s share of the spotlight. In 2012’s Uncanny Avengers #1, Havok finally has his big break when he is made the leader of the Avengers Unity division. Havok has quit being an Avenger after 2014’s ridiculous crossover arc Axis, where his memories were altered after time travelling to the future in an alternate reality dimension (don’t ask).
At heart, Cable has always been the leader of the x-Force, the mutant mercenary team from the future. But he has had his run-ins with the X-Men. Cable, when not engaged in taking care of Hope or leading a raid on a Sentinel convoy, has found himself in the past fighting alongside the X-Men on many occasions. Cable also has been a part of the Avengers Unity division since 2016. It was only recently that he decided to leave the group after he got out of a lengthy coma.

After the Unity squadron disbanded, Sunspot became the leader of his new superhero team called the U.S Avengers.
Sam Guthrie has always been am X-Man at heart. But there always comes a time where your alignments get the kick in the balls no matter how loyal you are.

Cannonball regularly part times as a superhero when need be.
He is always the villain. ALWAYS!! Or is he?? Sabretooth was part of one of the earliest iterations of the Avengers.

Sabretooth was also part of the Avengers Unity Squadron where he aided the team in one occasion before changing tracks to join Magneto’s Brotherhood.
12. Quentin Quire

The omega level telepath would later become an alien god and return back to Earth where he would star in his own reality TV Show.

The WCA heroes were reluctant to accept him but Quentin persuaded them with a promise of the immense funding he bought with him should they allow him to join their team.

For now, he is the principal of Jean Grey School for Higher Learning and is back to being a member of the X-Men.
