Cable and Deadpool are extremely close despite Deadpool's personality being obnoxious even at the best of times. Despite Deadpool's general lack of allegiances, he genuinely believes in what Cable attempts with Providence, and Deadpool was the first person Cable pictured/made psychic contact with while trying to decide whether to blow himself up. They were genetically commingled, so that "one phone call" would have happened even without intent....And Cable needed to make that contact to manipulate Deadpool into Doing The Right Thing.
Both Cable and Deadpool are well aware of their Life Partner status, especially evidenced when they both regularly called the time during a small falling out between them ("Small falling out" in this case being Deadpool's new membership in a mercenary group hired to destabilize Cable's fictional country Providence. Said membership was revealed when 'Pool shot Cable in the back of the head.) a "divorce". Despite their split, the two have a secret pact no one else has been clued in on; they will protect each other's loved ones if the other dies by destroying the deceased's safe houses.
Once when asked about his relationship with Cable by well-known gun-for-hire The Cat, Deadpool responded that it was a 'Don't ask/Don't tell deal'. Feel free to interpret that however, you wish.
Deadpool and Spider-Man seem to be heading into this territory in their recent 2016 series. Issue 12 has them spend Christmas together, and Deadpool mentions how much he appreciates Spider-Man's friendship. The feeling is mutual. They got each other gifts, and decide to open them at the same time. It turns out that got one another sweaters with their faces on them, but the faces are reversed on each sweater. They both go out wearing their sweaters, and say they ride and die together, and are "bad besties for life." Much like Cable & Deadpool, their relationship contains a bit of Ho Yay, if not more given Deadpool is genuinely trying to change his ways to gain and keep Spider-Man's respect. In addition to Itsy Bitsy, their "daughter" being created from their combined DNA. She refers to them both as "daddy."
Luke Cage and Danny Rand, also of Marvel Comics, with Luke going so far as to name his daughter after Danny.
Their close friends Misty Knight and Colleen Wing also are considered Heterosexual Life Partners, with Luke Cage going so far as to recommend the two get "gay married."
When Danny is asking Luke to join his new non-profit, he says 'I love you with every fiber of my being'.
Openly mocked by Spider-Man, in an issue where Luke's wife Jessica, upon finding out that Spider-Man was Peter Parker, gushed that they went to the same high school and she had an enormous crush on him. Later, Luke is clearly in a mood and not talking to Spidey, while Spidey tries to explain that he never really noticed her and it was years ago anyway. There's a pause, then Spidey lets fly with this one: "But you and Iron Fist broke up, right? 'Cause I'd like to take a shot at that action." Luke goes from looking mildly annoyed to seriously pissed.
Spider-Man is famous for having met, teamed up with, and/or fought every hero in the Marvel Universe, but his friendships with The Human Torch and Daredevil are the closest and oldest.
Matt Murdock and his best friend and law partner Foggy Nelson were roommates in college and started their own law firm after graduating. Foggy has spent most of Daredevil's history as Matt's Secret-Keeper, and after everyone in New York was given Laser-Guided Amnesia to forget Matt Murdock was Daredevil, he immediately re-revealed his identity to him. Notably, a guest appearance in a 2018 issue of Amazing Spider-Man shows Foggy attending an anonymous support group for the friends and families of superheroes who struggle to bear the secret alone.note Among the other attendees are Ganke Lee (friend to Miles Morales), Wong (friend of Doctor Strange), Pepper Potts (associate of Tony Stark), Willy Lumpkin (mailman of the Fantastic Four), and Mary Jane Watson (girlfriend of Peter Parker)
Foggy: I mean, he's my friend. Sometimes, I see the injuries, the wounds, and I just feel...helpless.
Supervillain example, Mentallo, and the Fixer. Though they "broke up" when Fixer joined the Thunderbolts, Judging by the MODOK's 11 mini, Mentallo stills misses the Fixer.
Fixer also seems to have this status with Baron Helmut Zemo.
Previously, villains Black Tom Cassidy and the Juggernaut.
Also Wolverine and Nightcrawler.
Also Nightcrawler and Colossus as well. Sometimes two would fight over the other like jealous girlfriends. Nightcrawler and Captain Britain too, though they didn't always get along.
Rachel Grey and Kitty Pryde are this, from Excalibur onwards, with the two usually being on the same team, rarely being seen apart for all that long, and Rachel being one of the bridesmaids at Kitty's aborted wedding to Colossus. It often drifted into Ho Yay, or a Pseudo-Romantic Friendship- they were creations of/developed by Chris Claremont, who was famous for doing a lot of both. Further complicating matters, in Rachel's Bad Future, Kate Pryde, her older version of Kitty, had been a close friend and a mentor, who sacrificed herself to save Rachel. Perhaps the crowning moments were when Rachel went into a miserable funk after Kitty got back together with Colossus in the 90s, when Kitty got ominously and angrily protective of Rachel's comatose body during the Excalibur era, and when Rachel, who thought she was about to die, hugged Kitty and tearfully asked, when she was born, if Kitty would take baby Rachel and 'give her a kiss hello'.
Magneto and Professor X: a tragic case of a broken life partnership and Depending on the Writer Magneto especially regrets that their ideologies have driven them apart.
In a similar, though more jarring sense, Cyclops and Wolverine, with their recent breakup and both sliding down different slopes. Prior to this, the two were often at each other's throats but in a manner similar to two brothers, and when push came to shove they'd be as thick as thieves. In fact, once Jean Grey (Scott's long time love and late wife, and the woman Wolverine had the hots for) died, thus removing the main source of their bickering, the two stopped arguing so much and became more openly close and friendly. Then Wolverine became a hypocrite and Cyclops became an extremist, and then Cyclops as the Dark Phoenix killed Professor X, and now the two can't stand each other - though before Wolverine died, they had it out (fought a monster, had a few drinks), with Cyclops pointing out Wolverine's hypocrisy, and Wolverine explaining this his main issue was the way that he felt that Cyclops kept justifying it/avoiding taking responsibility for what he'd done (whether he was responsible or not, on some level, is another matter, but it's a reasonable enough argument). After, they disagreed, but more amicably.
X-23 and Jubilee, the two 'daughters' of Wolverine who have similar issues. It's a tad darker than normal as it partially formed out of the two each agreeing to take the other down if they lose control.
Cannonball and Sunspot from New Mutants. The two boys quickly gravitated towards each other due to being the only guys on the initial team, and have been near inseparable since. At one point they get tired of being superheroes and break off from the New Mutants to go on a long-term holiday together, during which they're both drafted into the Avengers. When Cannonball finds himself a girlfriend there, Sunspot jokingly calls him a traitor. Then Cannonball and his wife leave to a distant planet to raise their son, only for Sunspot to show up after a few months with the (correct) assumption that Cannonball would immediately come back to Earth for whatever Sunspot has planned.
Rictor and Shatterstar of X-Force fame were this for a long time, along with that special touch of Ho-Yay, until finally the 'Heterosexual' part was thrown out.
Tony and Steve are almost in a bizarre, giant ass HLP Dodecahedron, given how many people they share this relationship with. As well as each other and the mentioned above, Tony, Depending on the Writer, has a, slightly more vitriolic, one with both Bruce Banner (one played up in the recent Avengers film) and Henry Pym, while Cap also has one with Clint Barton. Clint Barton, meanwhile, has one with Henry Pym too, making things all the more circular, while recent developments have given Hawkeye something similar with Captain Britain. Captain Britain, meanwhile, held a similar, though more aggressive, relationship with Nightcrawler, and, in-spite of introductions, a more pleasant one with Pete Wisdom.
In Guardians of the Galaxy, Rocket Raccoon and Groot. As the series went on, Rocket's relationship with Groot went from wanting The Big Guy for back up to this. And it only became more apparent after the Timely Inc. mini-series as they're currently the only active members of the Guardians of the Galaxy.
Jessica Drew and Carol Danvers. They're even approached as a pair during the recruitment drive in Avengers #2, while everyone else, except for Cannonball and Sunspot (another pair of Life Partners), got approached individually. Carol also has one with the other Jess, Jessica Jones; not surprising, given that Jones was an expy of Drew when first created.
