Fans of Marvel Comics and the Marvel Cinematic Universe alike know that there's nothing more exciting than seeing superheroes team up to take down a common enemy. Villains like Thanos, Ultron and Doctor Doom have forced several heroes with drastically different personalities to work together over the past several decades of comics, television shows and films, and a number of these surprising alliances ended up resulting in lasting friendships.
Crossover events and superhero team-ups have presented fans with some really unusual Marvel pairings over the years, and the most memorable friendships are always the ones that make absolutely no sense and produce drama and laughs behind the scenes. These classic dynamic duos probably never should have become friends, but somehow, they've made it work.
20 PROFESSOR X AND MAGNETO
Both Charles Xavier and Erik Lehnsherr want what's best for mutantkind, but their ideologies couldn't be more different. While Professor X prefers to work with humans and earn their trust, Magneto believes mutants are the superior beings and shouldn't have to appease their inferiors.
Magneto was the X-Men's greatest rival for years and his Brotherhood of Mutants created countless problems for Xavier, but somehow, these two never stopped being friends. As soon as their fighting ceased, they had no problem just sitting down together and playing a civil game of chess.
19 GROOT AND ROCKET RACCOON
It may seem weird that an anthropomorphic raccoon with a love for weapons and a Flora Colossus with an exceptionally limited vocabulary could become best friends, but these two just figured out how to make it work.
Groot's solemn nature helps balance out Rocket when he's throwing one of his classic temper tantrums, and he's happy to let Rocket call the shots when he's being level-headed. Rocket loves to hop on Groot's shoulder when Groot is in his adult form, and Groot loves to take a ride on Rocket's shoulder when he's a baby.
18 DEADPOOL AND SPIDER-MAN
Spider-Man and Deadpool are both known and loved for their great sense of humor, but they don't always get along all that well. Wade is basically obsessed with the friendly neighborhood wall-crawler, but Peter finds the regenerating degenerate's inability to ever be serious quite problematic and he doesn't like how willing Deadpool is to end the lives of his enemies. Luckily for the many fans of these two heroes, Spidey managed to make things work for three years of epic team-ups in Spider-Man/Deadpool.
17 LUKE CAGE AND IRON FIST
Iron Fist and Power Man are interesting heroes on their own, but there's a reason these Heroes for Hire have shared the spotlight in crossover comics for over four decades now. Fans love the unconventional friendship shared between this master of mystical kung-fu and the hulking Harlem resident with invincible skin.
Danny and Luke's powers are as different as their personalities, but for whatever reason, their differences don't stop them from being an effective duo.
16 IRON MAN AND WAR MACHINE
Tony Stark prides himself on being a rebellious billionaire playboy, while James Rhodes is a government man who prefers to follow the rules and play by the book. They never should have become friends in the first place with such different preferences and personalities, yet few duos in Marvel are as tight as these two.
Rhodey was Tony's first choice to don the War Machine armor, and when he stepped down from being Iron Man in the comics, Stark was happy to turn the mantle over to his best friend.
15 VISION AND SCARLET WITCH
Scarlet Witch was first introduced as the mutant daughter of X-Men villain Magneto, while Vision was an android member of the Avengers. They weren't even the same species, but that didn't stop them from instantly bonding and forming a romantic relationship with each other in the comics.
Wanda and Vision's friendship formed quickly in the MCU as well, even though Vision was practically her babysitter in Captain America: Civil War. Before the events of Infinity War, they fell in love, and the upcoming Disney+ show WandaVision will further explore their unconventional relationship.
14 SPIDER-MAN AND THE SUPERIOR SPIDER-MAN
Doctor Octopus was one of Spider-Man's greatest enemies for decades, but when Otto Octavius switched bodies with Peter Parker, the former villain finally learned that "with great power comes great responsibility." He sought to prove that he could be a better hero than his old rival, and became the Superior Spider-Man.
Peter eventually got his own body back, but Otto combined his DNA with Peter's in a clone body so he could again become Superior Spider-Man. The two heroes don't necessarily consider each other friends, but they have teamed up several times and Peter often gives his fellow web-slinger advice.
13 BEAST AND WONDER MAN
Avengers historians know that the one of the team's all-time best friendships was the one shared between Wonder Man and Beast. Henry is a shy bookworm while Simon is very outspoken and loves the limelight, but these two loved to go out drinking together and revel in their bachelor lifestyle. They became inseparable, and went on countless adventures together inside and outside of the Avengers.
12 THE PUNISHER AND DAREDEVIL
The Punisher and Daredevil have fought—both with their words and their fists—on numerous occasions over the ethics of eliminating criminals. They don't agree on much, but Matt Murdock is still the closest thing Frank Castle has to a friend.
Frank seeks Matt's legal council whenever he gets into a sticky situation, and he goes out of his way to protect Matt whenever he's in danger. Once, the Punisher actually surrendered himself to law enforcement after Daredevil was imprisoned at Riker’s Island, to keep Murdock safe from the people he put away.
11 HUMAN TORCH AND SPIDER-MAN
It's surprising that Spider-Man and the Human Torch can get anything accomplished when they team up, because they both have a hard time staying serious and their competitive friendship often leads to each of them trying to one-up the other.
Spider-Man briefly took Johnny's place in the Fantastic Four for a period of time, and the rest of the team was probably thankful to not have both wise-cracking heroes on their roster at once.
10 WOLVERINE AND NIGHTCRAWLER
Wolverine is the best there is at what he does, and what he does isn't very nice. Nightcrawler, meanwhile, prefers non-violence and is one of the X-Men's most spiritual members. They're a rather unlikely set of friends, but they've become incredibly close over the years.
Logan and Kurt frequently go out drinking together, and enjoy pulling pranks on their fellow mutant teammates.
9 STAR-LORD AND GAMORA
Star-Lord and Gamora have become one of the most beloved duos in the Marvel Cinematic Universe, but their relationship doesn't make much sense. Peter is somewhat of a slacker and a goofball, while Gamora is often strictly business and would rather focus on the task at hand than dance around to some old tunes.
Sure, they balance each other out well and it's nice that Star-Lord taught Gamora to loosen up a bit, but these two probably wouldn't have become friends at all in real life.
8 ANT-MAN AND WASP
Here's another Marvel Cinematic Universe twosome that isn't always the most believable. Hope is all business, but Scott loves joking around. Scott took ages to figure out how to become a competent superhero, while Hope was practically a natural.
If there wasn't so much attraction and chemistry between these two, it's more likely that they'd become enemies than friends.
7 DEADPOOL AND CABLE
Cable is one of the most serious and professional mutants in Marvel Comics, so readers were understandably surprised when he became friends with everyone's favorite funnyman Deadpool. The time-traveling son of Cyclops and Jean Grey's clone has hilarious chemistry with the Merc with a Mouth—they're polar opposites and fight each other as often as they fight their enemies, but that's what makes them such a fun duo.
6 THOR AND LOKI
Loki spent most of his life on Asgard resenting Thor and planning his brother's downfall. He tried eliminating the God of Thunder in Thor and attempted to take over Earth in Avengers, but when they found a common enemy in Malekith in Thor: Dark World, these two formal rivals miraculously became friends.
No matter how many times Loki betrayed Thor and proved unworthy of his trust, Thor gave his brother another chance. They teamed up again in Thor: Ragnarok, and the trickster god lost his life trying to help Thor in Infinity War.
5 GAMORA AND NEBULA
Thanos raised Gamora and Nebula as sisters, but he never intended for them to actually like each other. The Mad Titan loved forcing these two to fight each other, and whenever Gamora defeated Nebula, he replaced her body parts with cybernetic enhancements to make her a more formidable fighter.
Nebula grew to resent Gamora as a result, but when Gamora apologized in Guardians of the Galaxy vol. 2 and the two sisters realized that Thanos was the one to blame for their rivalry, they finally put aside their differences and became friends.
4 PETER PARKER AND MILES MORALES
In Marvel's Ultimate universe, Miles Morales became Spider-Man after Peter Parker lost his life in a fight against the Green Goblin. Thanks to some universe hopping, however, Miles eventually found himself on Earth-616 and could finally train with and befriend his fallen idol.
Peter and Miles have since teamed up on numerous occasions, and while Peter wants Miles to become his own hero and is occasionally weirded out by the existence of another Spider-Man, he's always willing to offer help and guidance when needed.
3 CYCLOPS AND EMMA FROST
Cyclops and Emma Frost's relationship can be quite the controversial topic with X-Men fans. Some people will always say that Cyclops' soulmate is Jean Grey, and refuse to accept Emma as a hero because of her villainous start with the Hellfire Club. Some, however, say that Scott's bond with Emma was stronger than the one he shared with Jean, and prefer to see Cyclops with the White Queen.
They both have a rebellious side, care a lot about mutantkind and are both great leaders, so even though they started out as enemies, it does make some sense they they became close.
2 HUMAN TORCH AND THE THING
If Johnny Storm and Ben Grimm weren't founding members of the Fantastic Four, they probably never would have become friends. Ben is far too serious and boring for Johnny's liking, and Johnny makes too many jokes at his teammate's expense for Ben to possibly enjoy spending time with him.
The Thing and the Human Torch are still always there for each other, though, despite their many fights and differences.
1 WOLVERINE AND KITTY PRIDE
Wolverine is one of the most brutish members of the X-Men, but Kitty Pryde has always been able to see good in Logan and chose him as her personal mentor over more similar-minded mutants like Jean Grey, Storm or Nightcrawler.
Over the years, Wolverine has helped Shadowcat master her powers and learn how to fight, and he goes out of his way to teach Kitty life lessons and show her who she really is. Logan often loses faith in himself and worries about whether or not he's doing the right thing, but he does everything he can to keep Kitty from having those same concerns about herself.
