History Main / ConquerorFromTheFuture

* In ''Film/StarTrekFirstContact'', [[TheVirus the Borg]], realizing that they're having a lot of trouble assimilating TheFederation, travel back in time to prevent the Federation from being formed (and assimilate the Earth in its more vulnerable past). It initially succeeds, as a new timeline is created where the Earth is populated by Borg drones, but the Enterprise was protected from the changes due to being in the wake of the Borg ship's "temporal vortex". The Enterprise follows them into the past and sets history right.
* ''Film/StarTrek2009'': After being sucked back in time, Nero decides to get "revenge" on Starfleet for not averting a [[NegativeSpaceWedgie oddly powerful supernova]] in time to save his home planet. Of course, Starfleet has no idea what he's talking about.

* In the 2009 ''[[Film/StarTrek Star Trek]]'' film, after being sucked back in time, Nero decides to get "revenge" on Starfleet for not averting a [[NegativeSpaceWedgie oddly powerful supernova]] in time to save his home planet. Of course, Starfleet has no idea what he's talking about.

* Creator/MarvelComics has Kang the Conqueror, Rama-Tut, the Scarlet Centurion, and Immortus. The catch is that these are all actually the same guy: he's traveled through time so often, and created so many [[AlternateTimeline Alternate Timelines]], that there is now an entire LegionOfDoom called the Council of Kangs made up entirely of his own iterations. Immortus, it seems, is the original Kang and the oldest, who is now a BoxedCrook: forced to spend eternity undoing the ContinuitySnarl that is the Marvel universe thanks largely to him.
** The miniseries ''ComicBook/AvengersForever'' is little more than an attempt to tie together all those threads. One issue was spent entirely summing up Kang's convoluted history.
** The Scarlet Centurion also appears in Marvel's alternate-universe ''ComicBook/SquadronSupreme'' limited series, albeit without the ContinuitySnarl baggage.
* Also from Marvel comics, we have Zarrko the Tomorrow Man, who came from a perfect pacifist utopia but got so bored of it he decided to snatch a nuke from the past and take over. He and Kang know each other and don't get along; they've had time wars occasionally.
* ComicBook/DoctorDoom also occasionally plays this role, thanks to his invention of the Time Platform. [[InTheBlood He happens to be a proud descendant of the aforementioned Rama-Tut.]]

** Lesser known but equally badass are JSA antagonists Extant (a two-bit hero turned into a deranged incarnation of Chaos) and Per Degaton (a time-travelling Nazi).
* Two of Comicbook/TheFlash's most powerful villains are minor examples of this trope. Abra Kadabra, a mad terrorist from the 64th century, uses futuristic technology to pass himself off as an EvilSorcerer. Professor Zoom, meanwhile, is a criminal from the 25th century who uses future technology to become the Barry Allen Flash's EvilTwin and ArchEnemy.
* In the ''ComicBook/DCOneMillion'' story arc, ComicBook/VandalSavage, an [[{{Immortality}} immortal]], evil JuliusBeethovenDaVinci who has been alive since 50,000 B.C., manages to do this, when it is revealed that he is still alive in the 853rd century and has hatched a plot to send a deadly cybernetic virus backward in time to change the future.

* The Future, one of the five heads of the Fraternity in Creator/MarkMillar's ''Comicbook/{{Wanted}}'', is a Conqueror From The Future clearly based on Kang and his crew. Only [[StupidJetpackHitler crossed with Nazis]].
* Max Bubba in ''Comicbook/StrontiumDog'', who travels back to the end of the eighth century and sets about wrecking the timeline in order to get revenge on [[FantasticRacism the future]]. It's unclear just how aware he is that he's wrecking the timeline.

* The Disney comic [[http://coa.inducks.org/story.php?c=D+99119 "The World Begins And Ends In Duckburg"]] features a villain from the future who comes and turns off all electricity. (AnAesop follows about not relying on modern technology.)
* The robot [=Futur10n=] from ''ComicBook/TheIncredibles'' comics. His arsenal includes [[DevolutionDevice Devolution Bombs]].
* Also from the DCU, Xotar the Weapons Master, a criminal from the 120th century who fought the ComicBook/JusticeLeagueOfAmerica. His first attempt (the JLA's second ever appearance, in ''ComicBook/TheBraveAndTheBold'' #29) actually addressed the history problem: Xotar had found a fragmentary old historical document mentioning that he had traveled to 1960 to defeat the Justice League. The story ends with the document being written, revealing that with all the missing portions in place it is an account of his ''unsuccessful attempt'' to defeat the Justice League.
* Two separate future versions of {{ComicBook/Brainiac}} have pulled this, the more successful being the 64th century native Brainiac 13, who nearly conquered the entire 21st century universe in ''ComicBook/OurWorldsAtWar''.
* ''ComicBook/{{Vampirella}}'': Professor Benjamin Quatermass originates from a timeline 100 years in the future when humanity has abandoned the Earth's surface for floating cities. In a variation, he invades the past to make sure that his ancestor will ''invent'' time travel technology, allowing for the incredibly complicated series of events to ensure that he'll control all timelines.

* ''VideoGame/{{Onimusha}} 3: Demon Siege'' features a rare inversion as the villains from the distant past use time travel to take over the future: specifically [[DemonKingNobunaga Nobunaga Oda]] uses a magic portal to send demon hordes from Japan to invade modern day France.

* Creator/MarvelComics has Kang the Conqueror, Rama Tut, the Scarlet Centurion, and Immortus. The catch is that these are all actually the same guy: he's traveled through time so often, and created so many [[AlternateTimeline Alternate Timelines]], that there is now an entire LegionOfDoom called the Council of Kangs made up entirely of his own iterations. Immortus, it seems, is the original Kang and the oldest, who is now a BoxedCrook: forced to spend eternity undoing the ContinuitySnarl that is the Marvel universe thanks largely to him.

* ''VideoGame/MOTHER3'': [[spoiler: Inverted by Porky who traveled from the past and conquered a [[AfterTheEnd post-apocalyptic]] future with a primitive rustic society.]]

* In ''Manga/MahouSenseiNegima'', Chao Linshen is a subversion: the major antagonist for a huge portion of the story, bringing advanced technology from the future to meet her goal, she seems like this, but with two key differences: a) she doesn't want to conquer the world, just break the ExtraStrengthMasquerade earlier than "scheduled" and thus prevent a tragedy, and b) she's arguably not even a WellIntentionedExtremist, because she specifically ''avoids'' going to moral extremes to avoid becoming one: She doesn't lie, and [[TechnicalPacifist doesn't kill]]: her army of robot minions are equipped with [[TheNudifier disarmament beams]].

* [=Futur10n=] from ''ComicBook/TheIncredibles'' comics.

* Quint, an evil version of ''VideoGame/MegaManClassic'' from the time just before VideoGame/MegaManX's awakening, or possibly an alternate timeline, travels back in time to menace his past self in the second and fifth GameBoy games and the UsefulNotes/WonderSwan game ''[[VideoGame/RockmanAndForteMiraiKaraNoChosensha Mega Man & Bass: Challenger from The Future]]''.

->'''Cueball''': Well, you know what they say, the past is a foreign country-\\
'''Black Hat Guy''': -with an outdated military and huge oil reserves... hmmm...
-->-- ''Webcomic/{{xkcd}}'' looks at it from the other direction.

* {{Subverted}} in ''WesternAnimation/SabrinaTheAnimatedSeries:'' Sabrina goes back to ancient Rome with [[TheLibby Gem]] and the two wind up in front of UsefulNotes/JuliusCaesar. Gem tries to intimidate him with a flashlight, but he's [[DeadpanSnarker less than impressed]].

* ''Flight from Tomorrow'', by Creator/HBeamPiper. A future dictator escapes a revolution with a time machine, and is determined to carry out this trope, then return with an army to seek revenge! Unfortunately he turns out to be a WalkingWasteland because future mankind has become acclimatized to high levels of radiation after a series of atomic wars; twentieth century humans track this radioactive TyphoidMary and carpetbomb the valley he's in, then fill it with concrete from one mountainside to the next.

* ''Series/DoctorWho'' is full of these. The two most prominent examples are the Master, who is the EvilCounterpart to the Doctor's time traveling alien, and the Daleks, who are {{Cyborg}} aliens. Both want to conquer the universe... in all time periods, past, present, and future.
** Arguably the most prominent new series example appears in the form of the Toclafane [[spoiler: who are later revealed to be the mangled remains of humanity from the far future, having traveled into the past with the help of the Master in order to escape the end of the universe.]]

* Also from the DCU, Xotar the Weapons Master, a criminal from the 120th century who fought the JusticeLeagueOfAmerica.

* ''VisualNovel/Sunrider'': [[spoiler:Inverted by Crow Harbor, an [[AbusivePrecursors ancient Ryuvian warlord]] from two thousand years in the past. Having accidentally transported himself into the present in a failed attempt to alter the outcome of a battle in his favor, and having broken his time machine in the process, he decides to conquer the galaxy and rebuild the Holy Ryuvian Empire]].

* In the ''Series/StarTrekTheNextGeneration'' episode "Time's Arrow", MarkTwain believes Data is this trope.

* {{Subverted}} in ''WesternAnimation/SabrinaTheAnimatedSeries:'' Sabrina goes back to ancient Rome with [[TheLibby Gem]] and the two wind up in front of Creator/GaiusJuliusCaesar. Gem tries to intimidate him with a flashlight, but he's [[DeadpanSnarker less than impressed]].
