->''"I'm a Time Lord. I'm the ''last'' of the Time Lords."''
-->- '''The Ninth Doctor''', two episodes into the ''Series/DoctorWho'' revival

So, you've got a character with their own series. And they've got a whole supporting cast of characters with similar powers, [[TrueCompanions almost a super-powered family]]. To make the character more "special", they get rid of all the similar characters.

Inversion of TheChosenMany, where a unique character becomes part of a group of similarly-powered characters. Although a LongRunner (like many comic book series) might go back and forth between the two repeatedly.


* The two most famous examples both involve TheDCU. Has happened repeatedly to GreenLantern, and the ResetButton has been pressed every time. The great Power Battery exploded, leaving only a few Lanterns active. ...but then the Guardians were brought back, rebuilt, and recruited new Corps members. ...so a few years later, Hal Jordan [[FaceHeelTurn went crazy-evil]] and killed off most of the Corps, leaving Kyle Rayner as the only one with the power. ...until he got a copy of Hal's original ring, which could create new copies, brought back the Guardians, and recruited new Corps members. And so on.
* The biggest ComicBook/PostCrisis change to Comicbook/{{Superman}} was the decision that "last son of Krypton" meant ''last'', as in no other Kryptonians ever, period. General Zod becomes a Russian, Kandor becomes an alien ghetto and thus devoid of actual Kryptonians, ComicBook/PowerGirl becomes an [[{{Atlantis}} Atlantean]], and ComicBook/{{Supergirl}} becomes... uh, [[ContinuitySnarl you'd better see that entry for yourself]]. They've lightened up on that in recent years, without returning to constantly tripping over one more Kryptonian a la pre-Crisis comics (or ''Series/{{Smallville}}''), as various writers attempted to reclaim the concepts ''without'' hitting the ResetButton -- [[http://en.wikipedia.org/wiki/New_Krypton at least, so fa-.]]
** ''WesternAnimation/SupermanTheAnimatedSeries'' handled this by making Supergirl from a nearby planet (thus getting the same powers and suffering the same fate as Krypton). And Krypto is [[MythologyGag Bizarro's pet... thing.]] (The actual dog himself did make a few [[TheCameo cameos]]).
* Done to the entire ComicBook/JusticeSocietyOfAmerica in ''ComicBook/LastDaysOfTheJusticeSociety'', to get rid of the extra ComicBook/TheFlash, extra ComicBook/GreenLantern, extra Hawkman, etc. Naturally, they were brought back several years later. And then most of them were killed off in ''Zero Hour'' [[CListFodder just to crank up the drama]], leaving Wildcat, Jay Garrick (the original Flash), Ted Knight (the original Comicbook/{{Starman}}), and Alan Scott (the original Green Lantern).
** Amazingly, the JSA was rebuilt by three of those four (with [[spoiler:Ted Knight retiring permanently and dying at the end of the {{Comicbook/Starman}} series]]), using [[LegacyCharacter legacies]] and the occasional resurrected character. Even then, some resurrected old-school JSA members, such as [[spoiler:the first Hourman, who came back during Black Reign]], stay retired. The JSA has a ''lot'' of legacies.
** With the ''ComicBook/{{New 52}}'', the Justice Society has suffered a major legacy implosion, with the all of the children and grandchildren wiped from existence and the original JSA members becoming young again. The divide between ''ComicBook/{{Earth2}} and the main DCU also has brought up a kind of OneSteveLimit, in that Franchise/TheFlash and Franchise/GreenLantern are the only superheroes with ongoing stories to have versions in both universes[[note]] Earth 2 also had versions of Batman, Superman, and Wonder Woman, but they get killed off in the prologue of the series[[/note]]. Every other superhero is editorially confined to either one continuity or the other. So, for example, ComicBook/TheSpectre, traditionally a JSA character, is now in the main DC universe instead of Earth 2 with the rest of the rebooted Golden Age characters.
* During ''ComicBook/InfiniteCrisis'', Bart Allen absorbed the entire [[MetaOrigin Speed Force]] into himself, and became the only ComicBook/TheFlash-style super-speedster. The ensuing series lasted only 13 issues, and ended in favor of a ''Flash'' series by Mark Waid, the guy who pretty much built the previous "Flash Family", focusing on Wally West and his [[SpinOffspring superpowered kids]].
** ''TheFlash'' suffered this again in the ComicBook/{{New 52}}. Wally West is who knows where, Jay Garrick is on [[ComicBook/{{Earth 2}} another Earth]], Max Mercury and the Quicks could be either. Bart Allen still exists, but doesn't currently have a real connection to Barry.
* Following "War Games", Franchise/{{Batman}}'s TrueCompanions were imploded piece-by-piece, with the exceptions of marketable stalwarts Robin and Nightwing. Orpheus dead, Spoiler dead [[StuffedIntoTheFridge for dubious reasons]], long-time confidant Leslie Thompkins implicated in killing the latter "to teach Batman a lesson", current Batgirl realizing a FaceHeelTurn, former Batgirl Oracle bombed out of her headquarters and sent away from Gotham City along with her Birds of Prey team, Onyx inexplicably vanished from the books, Commissioner Gordon (who'd already retired by then) moving out of Gotham, the rest of the GCPD pretty much turning against him... Some of these got [[AuthorsSavingThrow undone]]: Steph [[BackFromTheDead wasn't really dead]], and became the new Batgirl, Cassie turned out to be under mind-control and joined Batman Incorporated as Black Bat, Jim Gordon moved back and was reinstated as commissioner, the GCPD resmued relations with Batman, and Babs returned to the Bat-fold as Batman Inc's computer specialist. As of the ComicBook/{{New 52}}, Babs is Batgirl again, however the fate (or existence) of the others is currently unknown. (WordOfGod is that Stephanie and Cassandra are "[[ChuckCunninghamSyndrome toxic]]"). Both Cassandra and Stephanie later returned, but thanks to the new continuity, neither girl was ever Batgirl.
* Comicbook/{{Aquaman}}'s supporting cast were killed off one by one to add drama to the book and boost sales.
* This was the major criticism of ''ComicBook/BlackestNight'' (generally well-received otherwise) and ''ComicBook/BrightestDay''. In the former, the number of non-legacy characters who died and ''stayed'' dead was exactly one, [[Comicbook/{{Aquaman}} Tempest]], with other casualties including [[ComicBook/{{Hawkman}} Hawkgirl II]], [[ComicBook/HawkAndDove Hawk II]], Damage (one of the numerous inheritors of the original [[ComicBook/TheAtom Atom]]'s mantle), Gehenna Hewett (half of ComicBook/{{Firestorm}} II), and Doctor Polaris II, the last of these only receiving an offhand mention and never actually being shown. Seeing a pattern here? ''ComicBook/BrightestDay'' killed off yet another Atom legacy and [[ComicBook/MartianManhunter Miss Martian]] was presumed dead for a couple issues, too. The fans didn't take any of this particularly well, and it added more fuel to the EpilepticTrees that the DC suits want UsefulNotes/{{the Silver Age|of Comic Books}} back.
** It got to the point that editor Ian Sattler had to defend the company's commitment diversity in the face of complaints about how DC was systematically killing off its [[AffirmativeActionLegacy more racially diverse Legacy Characters]] in order to bring back their white predecessors.
*** The ComicBook/{{New 52}} reboot then tried to answer some of this. Jason Rusch (the black Firestorm) shared ownership of the identity with the original, and Ryan Choi was initially stated to be the only Atom. DC has since [[FlipFlopOfGod backtracked a little]] by introducing a new, female Atom instead [[spoiler:who turned out to be evil]].
* As you might notice above, this happens to ''ComicBook/{{Hawkman}}'' with some regularity, in varying degrees. It never sticks, and only ever makes the MindScrew of a ContinuitySnarl that is Hawkpersons even more [[TangledFamilyTree tangled]].
* In [[ComicBook/{{New52}} The New 52]] Jaime Reyes is now the first ''ComicBook/BlueBeetle''. Well, he isn't the first user of the Scarab, but the previous user was a ''Mayan astronomer'', meaning both Dan Garrett and Ted Kord apparently no longer exist.
** Ted Kord is definitely around running Kord Industries, but he's not a superhero. (Yet?)

* Marvel has done this with Scott Lang, the second [[ComicBook/AntMan Ant-Man]]. He was killed off in ''Comicbook/AvengersDisassembled'', but almost as soon as he was resurrected in ''Comicbook/TheChildrensCrusade'', Marvel killed off Eric O'Grady, Lang's successor. Now Lang stars in ''Comicbook/{{FF}}'' while Hank Pym, the original Ant-Man, operates without a CodeName [[NotWearingTights or costume]].
* The same thing happened with ComicBook/TheVision, who also died during ''Disassembled''. As soon as Creator/BrianBendis brought the original Vision back and had him rejoin ''Comicbook/TheAvengers'', the teen Vision from ''YoungAvengers'' [[DroppedABridgeOnHim had a bridge dropped on him]] in the finale of ''Comicbook/TheChildrensCrusade''.
* MarvelComics did this to the ComicBook/XMen with ''House of M/Decimation''; millions of mutants all over the world were depowered, except for 198, supposedly chosen at random. Very few characters anyone cared about at all lost their powers, and those who did gained them back pretty quickly. Recently, a new mutant baby has been born, signaling the return of mutants to the wider MarvelUniverse.
* In a storyline right before ''ComicBook/SecretWars2015'', an intelligent version of ''ComicBook/TheIncredibleHulk'' known as Doc Green ran around the Marvel Universe, depowering all the other gamma-powered characters regardless of alignment, exposure, or popularity. [[spoiler: At the end of the storyline, the only remaining gamma mutates were Hulk himself, ComicBook/SheHulk and the super villain The Leader.]]

* The 2005 revival of ''Series/DoctorWho'' set up the complete destruction of Gallifrey in its BackStory, leaving the Doctor as the last of the Time Lords, [[spoiler: until the Master returned at the end of the third season.]]
** Unlike most examples of this trope, however, Series/{{Doctor Who}}'s LegacyImplosion has (a) been reasonably popular and (b) stuck. This was because (a), the new series is phenomenally popular, and a large faction of fans of the older one viewed the Time Lords as a dull culture with a severe tendency to provoke ContinuityLockOut. And as for (b), the only Time Lords seen in the new series were [[spoiler: the Master, and a ShadowArchetype seems like a reasonable exception to a "last of the..." rule]], and some others brought back briefly and temporarily by TimeTravel. At some point Gallifrey might be brought back, who knows, but six seasons and counting is a longer duration of this implosion than most.
** [[spoiler: Though Gallifrey was eventually saved, absolving the Doctor the guilt of the genocide, it remains stuck in a pocket dimension, preserving the same effect as far as plots are concerned. The exception so far is, once again, the Master.]]
