* FanNickname: After Steve Rogers was revealed to be a [[spoiler:Hydra agent]] in Nick Spencer's "Captain America: Steve Rogers", fans have started to call him [[spoiler:Captain Hydra]].
* KeepCirculatingTheTapes: Until the last couple of years, there were very few Captain America trade paperbacks and those few that did exist were reprints of recently published stories. Since then, the last year and a half of Steve Englehart's Captain America run (the Secret Empire and Nomad stories) have been collected, along with all of Jack Kirby's 70s Captain America run, key storylines from Mark Gruenwald's Captain America, and all but one key issue of Mark Waid's first Captain America run (omitted as it is part of an OldShame of Mark Waid, even though it contains major plot advancement for his [[ComicBook/{{Agent 13}} Sharon Carter]] storyline).
* RunningTheAsylum: As with all comic books, this is inevitable, but two instances of well-received re-retcons stand out in recent years:
** EdBrubaker's first story line for Captain America was ''The Winter Soldier'', which rehabilitated KidSidekick ComicBook/BuckyBarnes from a laughingstock ComicBook/{{Robin}} wannabe who only existed to make Steve sad into a fan-favorite badass who's had two ongoings of his own. He's said in interviews that when he learned, as a kid, that the oft-flashbacked-to story of Bucky's death wasn't actually a story of its own but a retcon that the first thing he'd do if ever wrote Captain America was undo it. He did, and crowned it with Bucky's run as Captain America. Brubaker has also said it's a good thing Mark Waid brought Sharon Carter back during his run, or else he'd have done that, too.
** Rick Remender's run brought ComicBook/TheFalcon in on the third story line and slowly reintegrated him until, like Bucky, it was time for him to take his turn as Captain America. Sam's second issue as Cap ''eviscerates'' the retconning of Sam's backstory as a good-natured social worker who was marooned on an island and fought the local injustice into being a thug and criminal who was brainwashed with false memories by the Red Skull to be a sleeper agent against Steve. Not only does Sam reject the retcon as being the true false memories, he says that the Red Skull was ''counting on'' everyone who heard it being racist enough not to question it. Remender, like Brubaker, has since said that he's been wanting to eliminate that story since he read it as a kid.
* WhatCouldHaveBeen: J. M. [=DeMatteis=] wanted to have Captain America stay an 80 year old man/give up being Captain America to be a peace activist in Captain America #300 and have the issue end with Nomad assassinating Cap, in order to shame the US and the Soviet Union into embracing peace. Oh and a recently introduced character known as Black Crow (a Native American hero) would have become the new Captain America.
** Roger Stern and Creator/JohnByrne once pitched a "Bucky Returns" storyline where Captain America would find that ComicBook/BuckyBarnes survived the plane explosion, but had lost his arms and legs and was disfigured (but not Literature/JohnnyGotHisGun disfigured, as far as Bucky simply having his face burnt and having full speech/hearing/sight). Bucky would call for Captain America after finding out that he was going to die, leading to a tearjerker scene as Cap would be reunited with Bucky to say hello to him, before dying.
** After his return in Captain America: Reborn, Steve originally was going to take the Shield back. However, seeing that many fans had grown to love Bucky in the Role of Cap, they decided to let him be Cap. So they temporarily shared the title.
** Cap's original name was slated to be "Super-American", but Creator/JackKirby & Joe Simon decided on "Captain America" for the name, citing that there weren't enough "Captain" superheroes.
** In the late 90s, Marvel and Saban were planning a solo animated series for Cap on Creator/FoxKids, and stories, character models, and a [[https://www.youtube.com/watch?v=Sd7VinvTfiw one-minute pitchfilm]] were all made, but was canned because of Marvel's bankruptcy; its slot in the Fox Kids lineup was filled by ''WesternAnimation/TheSecretFilesofTheSpyDogs''.
** A Captain America musical was planned in 1985, in the hopes of duplicating the success of Theatre/{{Annie}}. Insufficient financial backing meant that the project would never make it to the Broadway stage.
* WordOfGod: Invoked by writers after ''Comicbook/CivilWar'' to declare that Steve Rogers was [[BlatantLies killed off for real]].*
* ZeroEpisodeWonder: A cartoon based on the seires was scheduled to premiere on Creator/FoxKids in the fall of 1998, but the bankruptcy of Creator/MarvelComics meant it was not to be.
