* There are many multiverse fics where MCU characters somehow interact with their comic or cartoon counterparts. This is especially true with Steve and Tony fics, as the duo's relationship is very prominent in a lot of different realities in different ways; for example, their decade long angsty friendship in main comic continuity, domestic co-captaincy in ''WesternAnimation/AvengersAssemble'' or straight-up being married in Earth-3490. Alternative versions of them are mostly used as foils/reflections of MCU Steve x Tony's relationship.

* After ''Film/CaptainAmericaTheWinterSoldier'', many stories have been focused on Steve trying to rehabilitate a broken Winter Soldier/Bucky, who is sometimes seen suffering from PTSD, guilt or other types of mental issues due to his brainwashing, mistreatment, and assassination orders by HYDRA. Common beats include eschewing canon compliance past CA:TWS, a first act or prologue where Bucky is in the wind and Steve has to track him down, Steve and Bucky reuniting much earlier and/or under different circumstances than they do in canon, Tony learning the truth of his parents' deaths through less-traumatic ways than how he actually finds out in canon, Steve and Bucky moving into Avengers Tower, and Tony working on Bucky's arm. Fics are generally split on whether Bucky joins the Avengers, or chooses to give up fighting for good (and potentially motivates Steve to do the same).

* Stories that turn Peggy into a supersoldier like Steve are also quite common. This is often done by way of a BloodTransfusionPlot, in which Peggy is severely injured and Steve is the only person around who shares her blood type. He gives her his blood, and she gains at least some of his powers. Authors of more explicit stories sometimes invoke DeusSexMachina instead, with the general effect remaining the same. Alternatively, Peggy is used as a [[TestedOnHumans test subject]] for some other variant of the serum, and she gets her powers that way. In most cases, Peggy getting Steve's powers leads to her being frozen with him and them waking up in the present day together. This became HilariousInHindsight and something akin to AscendedFanon with the ''WesternAnimation/WhatIf2021'' series, the very first episode of which consists of [[ForWantOfANail Peggy receiving the serum instead of Steve and becoming Captain Carter]]. [[spoiler:And when the Watcher informs Peggy in the Season 1 finale that Steve was meant to receive the serum in the Sacred Timeline, Peggy replies that would've been quite the sight, her tone of voice making it clear that--though this Peggy fell in love with her universe's Steve [[SingleWomanSeeksGoodMan for the same reasons as her main counterpart]], even when he's still the scrawny kid from Brooklyn and she's now a {{statuesque|Stunner}} AmazonianBeauty--she's ''very'' interested in [[EatingTheEyeCandy taking a look at a post-serum Steve]].]]

* Fics where Peter Parker visits the Avengers tower on a field trip with his school are common among the MCU Spiderman fandom. Tony often has [[HappilyAdopted Peter as his son]], occasionally even his blood son from his pre-Afghanistan womanizing days. Expect a {{Flanderization}} of Flash that lines up more like a dumb physical bully than the nerd rival as he is in canon.

* A post-''Endgame'' scenario that's gained some popularity, especially among Stucky shippers, entails what's known as the "2012-verse"- the timeline where Steve steals Loki's scepter by claiming to be HYDRA, gets into a fistfight with himself, and tricks his way out of the fight by telling his 2012-self that Bucky's alive. It's been surmised that these would kick off the reveal of HYDRA early and, on a lighter note, more than likely lead to Bucky's rescue under less-traumatic circumstances.

* Many people have wondered what would have happened if the ''other'' half were snapped in ''Infinity War'' like [[https://www.youtube.com/watch?v=5rKkv9xWZ0s here.]] Even if it's not the exact other half, many people have wondered if there was any other random combination other than the one depicted. Given the franchise has LoadsAndLoadsOfCharacters, there's over fourteen million possible scenarios.

* There is heavy amounts of multiverse fics where MCU characters somehow interact with their comic or cartoon counterparts. This is especially true with Steve and Tony fics as the duo's relationship is very prominent in a lot of different realities in different ways, such as their decade long angsty friendship in main comic continuity, domestic co-captaincy in ''WesternAnimation/AvengersAssemble'' or straight-up being married in Earth-3490.

** Steve is the most popular target of this, and it's almost always given a full "role reversal" treatment where Steve falls off the train and Bucky is forced to become Captain America in Steve's place only to crash the ''Valkyrie'' and get thawed out in the future. A few versions of the story will depict him as a direct analogue of the Winter Soldier, such as in the ''[[https://archiveofourown.org/series/340963 One More Troubled Soul]]'' series. In such scenarios, most versions of this what-if scenario will depict Steve as "Captain HYDRA" and wearing a [[EvilCostumeSwitch modified]] version of his costume based off of the one in ''WesternAnimation/IronManAndCaptainAmericaHeroesUnited'' (which featured a few plot points similar to those of ''The Winter Soldier'', where Steve was brainwashed by the Red Skull). Also, whereas Bucky was an ExtremeDoormat who was forced into compliance via horrific torture, Captain HYDRA more usually tends have been brainwashed via MoreThanMindControl and thus retains more agency and enthusiasm in his actions.

* Another interesting scenario that's gained some traction following the release of ''The Winter Soldier'' entails WhatIf scenarios where other characters are either kidnapped or raised by HYDRA and brainwashed into becoming assassins. Steve is the most popular target of this, and it's almost always given a full "role reversal" treatment where Steve falls off the train and Bucky is forced to become Captain America in Steve's place only to crash the ''Valkyrie'' and get thawed out in the future, such as in the ''[[https://archiveofourown.org/series/340963 One More Troubled Soul]]'' series. Peter Parker and Tony Stark are tied for a distant second place- due to Peter's age, most fics have him under HYDRA captivity from toddlerhood, possibly kidnapped in the same incident that killed either his parents or Uncle Ben; and Tony is usually a second brainwashed HYDRA Asset alongside Bucky, kidnapped and brainwashed either when the Soldier killed his parents (with or without aging him down or moving their deaths further back in the timeline) or sometimes after the events of ''Film/CaptainAmericaCivilWar''. Sam Wilson is in an even more distant third place, with nearly all fics having him kidnapped in the same incident that killed his wingman Riley, and his wings being painfully grafted to his back like Bucky's arm. Others include Peggy Carter, Matthew Murdock, Rhodey (in a role-swap fic where Tony and Steve plus most of their associates swap places, with Tony growing up in the 1940s and becoming Captain America), and even Darcy Lewis.

* Similarly to the above, some stories turn Peggy into a supersoldier like Steve. This is often done by way of a BloodTransfusionPlot, in which Peggy is severely injured and Steve is the only person around who shares her blood type. He gives her his blood, and she gains at least some of his powers. Authors of more explicit stories sometimes invoke DeusSexMachina instead, with the general effect remaining the same.

In most cases, Peggy getting Steve's powers leads to her being frozen with him and them waking up in the present day together.

** Likewise, there are plenty of fics using time travel to change the end of ''Endgame''.

Given the franchise has LoadsAndLoadsOfCharacters, there's an infinite number of different scenarios.

* If an ''Endgame'' fic isn't a fix-fic, it will focus on either Peter and Harley acting as [[spoiler:Morgan Stark's big brothers]] or a NextGenFic where Peter leads a new incarnation of the Avengers or even the Young Avengers (with Cassie assuming the mantle of Stature or Stinger, Harley becoming Iron Lad, Lila Barton as the new Hawkeye, and occasionally Morgan becoming Rescue).

* Budapest fics. If you ship Clint/Natasha, you've probably written something about [[NoodleIncident Budapest.]] Any fic revolving around the members of Strike Team Delta (Clint, Natasha, and Coulson) is likely to have some references to Budapest. It's also common for Budapest to be the place where Clint initially recruited and/or encountered Natasha.

It's been surmised that these would kick off the reveal of HYDRA early and, on a lighter note, more than likely lead to Bucky's rescue under less-traumatic circumstances.

* You get lots of [[HeelFaceTurn Loki redemption fics.]] Usually forced as his punishment for the events of ''Film/{{The Avengers|2012}}'' -- a vast majority involve Loki being forced to live with the Avengers (who [[ReformedButRejected mistrust and/or are hateful towards with him]]) in order to learn humility.

* Fics where a teenage girl who is either a S.H.I.E.L.D. recruit from a young age or has superpowers and a mysterious past ends up joining the team and living in the Tower are common. [[MarySue You can probably see where most of these end up going.]]
