* BigLippedAlligatorMoment: Any scene involving Gerber's infamous Elf with a Gun.
* BrokenBase: The [[Creator/KeithGiffen Giffen]][=/=][[Creator/JMDeMatteis DeMatteis]][=/=][[Creator/KevinMaguire Maguire]] revival in 2005 has acquired a mixed reputation. On the one hand, fans of that creative team bought it up, making it one of the few successful attempts to revive the franchise since the 1970s. On the other hand, the miniseries' comedic approached rubbed some longtime fans the wrong way, especially when it turned Umar - canonically one of the most powerful villainesses in the Marvel universe - into a sex-starved diva who blows off Dormammu's big plan to reshape the universe his image in order to have sex with the Hulk, which has rendered her [[NeverLiveItDown all but unusable to subsequent writers, because nobody sees her as a serious threat anymore.]]
* DeaderThanDisco: Despite being one of Marvel's top books in the [[TheSeventies 1970s]], the title's disastrous "New Defenders" revamp, the resurgence of the ComicBook/{{X-Men}} as a popular franchise, the rise of various spin-off books (ComicBook/NewMutants, Comicbook/{{X-Factor}}, West Coast Avengers), and Marvel moving the founding Defenders back to being solo heroes (and Namor being absorbed into the Avengers franchise), the book fell into a state of mockery as far as as a relic of a past period and not fit for modern comic readers. Attempts by Marvel to revive the book has largely failed and the only real successful revamp was a mini-series by the guys behind ComicBook/JusticeLeagueInternational which basically reduced the concept to an "odd couple" comedy. The Marvel NOW! version, ''Fearless Defenders'' lasted 12 issues.
* FanonDiscontinuity: All Elf With A Gun appearances that were not written by Steve Gerber, including the pay-off to the whole thing where [[spoiler:it was revealed that the Elf was killing off nexus people who were a threat to the stability of the timeline and that the elf was part of a larger group of elves that were trying to stave off an apocalypse that would occur if the founding four Defenders stayed together]].
* HilariousInHindsight: At one point the team had Daimon Hellstrom, the Son of Satan, as a member at the same time as Devil-Slayer.
** Bendis's controversial revamp of the Avengers has been denounced as him basically taking the Avengers and turning it into the Defenders. This was acknowledged by Bendis himself several years into his run, when he had Nighthawk say "Clearly you guys are the Defenders," during a period when the team consisted of Wolverine, the Thing, Luke Cage, Jessica Jones, Doctor Strange, Mockingbird, Ms. Marvel, and Squirrel Girl.
** In ''VideoGame/MarvelVsCapcom3'', Dr. Strange would mention plans to put together an all-female Defenders team. Three years later...
* MyRealDaddy: Creator/SteveGerber.
* TheyWastedAPerfectlyGoodPlot: The [[http://www.supermegamonkey.net/chronocomic/entries/defenders_66.shtml 'Val in Valhalla']] arc, where a shunned Asgardian named Ollerus tries to take over Valhalla and uses a fake Valkyrie to dupe the Defenders into helping him. A letter in issue 73 asked why the story had a great set-up but was ultimately underwhelming, and it was a case of RealLifeWritesThePlot: writer David Kraft was leaving Marvel having only delivered the first part of this arc, and as the deadline came closer, it forced penciler Ed Hannigan to get Kraft's notes and work out a plot of sorts.
