History ApocalypseHow / ClassX2

* ''Franchise/StarWarsLegends'' features some weapons capable of doing this, such as the Sun Crusher (which causes stars to go nova, which would result in not only its own destruction but that of any system of habitable planets it may have maintained), and the Galaxy Gun, which can blow up planets anywhere in the galaxy without having to the leave the safety of the Empire's most heavily defended world. There's also the innocuously named Centerpoint Station, an [[LostTechnology ancient superweapon]] whose functions had been long since forgetten... until it's discovered (by the BigBad of the story, naturally) that, like the Sun Crusher, it can cause stars to go nova, along with other less directly destructive but still incredibly useful functions. {{Lampshade|Hanging}}d and parodied in ''Destiny's Way'' by Creator/WalterJonWilliams, in which Han Solo ridicules the proliferation of super-weapons (and by extension the authors responsible for giving every new ExpandedUniverse novel in TheNineties a new superweapon-of-the-week).

* Rogue planets, cold dark bodies that drift through the galaxy without orbiting a star, have effectively lost both their sun(s) and any fellow planets which were once their neighbors, although their original systems may still exist somewhere. A large enough Rogue planet could several disrupt the orbits of objects in any solar system it wanders into.

* ''Fanfic/ProjectGethinator'' ends with the last Perkele3000 mineral scanner in the galaxy (the same model of scanner used by Tali's idiot crewmate Prazza to accidentally blow up a star and kick off the plot of ''Fanfic/IngloriousBoshtets'') being used by [[spoiler:Admiral Xen]] to destroy the star of Eta Carinae and cause it to go hypernova, in a mad VillainousBreakdown-driven bid to destroy the Normandy and everyone on it. [[spoiler:Not only do Shepard and the others make it out in time thanks to Legion's quick hacking skills, but the Collector fleet Harbinger fielded to destroy Shepard warps in just in time for the blast to reach them]].

* The final {{Kamehameha|doken}} Cell of ''Anime/DragonBallZ'' launches has enough power to destroy the entire solar system. Since he's derived from, and is at that point many orders of magnitude stronger than, a being that can both survive in the vacuum of space and live through a planetary explosion, it seems like he could pull it off.
** [[spoiler:Then he gets killed by Gohan, who pulls a one-handed Kamehameha to finally destroy him.]]

* ''Film/StarTrekGenerations'' has Dr. Tolian Soran blowing up suns to alter the course of The Nexus.
** He's not merely ''blowing up'' suns; he's shutting them down. The way he forces their collapse, it causes the suns to forcefully expend their photospheres, destroying nearby planets.

* Say hello to Starkiller Base in ''Franchise/StarWars:'' ''Film/TheForceAwakens''. A gigantic planet-sized spaceship flies into a system and sucks up all the matter from its star. It then concentrates that matter and fires it across the galaxy at hyperspeed to destroy multiple planets in another system.
** Going beyond the destruction of the targeted planets, the planets in the system where the star was used will all not only die, but will end up flying off in all directions since they no longer have gravity holding them into their orbits.
** It has been implied that the firing of the weapon also causes a tear in hyperspace, possibly causing environmental damage to the galaxy itself.
** And even the destruction of Starkiller Base isn't a savior for the system it was in. All it did was cause the star swallowed by Starkiller Base to reconstitute in a new location. As a result, the system now has ''a new center of gravity'', and the orbits of its planets will be greatly disrupted, with all the havoc that may entail.

After converting her prison ship, [[spoiler:Ruby White]] in "Goodbye, Sarah Jane Smith" [[spoiler:travelled to many worlds, but warns Clyde not to look out for them, as they're "no longer with us".]]
* ''Series/StargateSG1'''s Samantha Carter [[RememberWhenYouBlewUpASun drops a stargate, opened onto a Black Hole, into a star, causing the star's mass to be depleted and explode]], destroying the BigBad's fleet, and [[spoiler:unfortunately throwing SG-1 into a different galaxy.]]
** Which ''makes no sense whatsoever'', given that long-lived stars have low masses, while Hypergiants have a life-span of one or two million years.
*** One possibility is by essentially having the core sucked out from the middle of the star, simulating the core collapse in high-mass stars that triggers a supernova.

*** Rodney doubtless also still resents the fact that Carter gets mad props for deliberately blowing up an entire star system, where as he only gets mockery for ''accidentally'' blowing up most of one...

* TabletopGame/{{Warhammer 40000}} naturally has one of these as well. If several Blackstone fortresses are linked, they can make a star go supernova and consequentially destroy the star system with it.

* ''Franchise/MassEffect'' brings us an example in the second game's DLC ''Arrival''. [[spoiler:Shepard has to blow up a [[PortalNetwork Mass Relay]] in order to slow down the invasion of the [[EldritchAbomination Reapers]], who prefer doing the Class X-3, long enough for the galaxy to get its act together and unite against them. Of course, in the process the exploding Relay took out the system it was in along with the 304,942 Batarian people living there, therefore all but guaranteeing war between the Human Systems Alliance and the Batarian Hegemony. Damned if you do, damned if you don't.]]
** [[spoiler:Until the third game rolls around, and we find out that the Reapers showed up and [[AlwaysABiggerFish obliterated]] [[EvilVersusEvil the]] [[TheEmpire Batarian Hegemony]] before they could fire any shots against humanity, proving to the few Batarian survivors that Shepard was [[TheExtremistWasRight in the right]].]]

* In ''Videogame/SpaceEmpires'', you can blow up a star, killing everything in the system. However, sometimes that's not enough -- you can recreate stars and planets, after all. If that's the case, [[ThereIsNoKillLikeOverkill turn the system into a Black Hole]], which also destroys the raw materials for planets. [[SerialEscalation Then again, you can also destroy the resulting Black Hole...]]
** Then put a new star back in place, and put a Dyson Sphere around it, making the materials for a massive sphere from virtually nothing...
* {{Creator/Sierra}}'s ''VideoGame/SpaceQuest'' series has the Star Crusher, a (surprisingly small) energy weapon capable of vaporizing planets and detonating stars, thus theoretically capable of wiping out whole solar systems in one shot. Fortunately, the mad scientist who created it was exiled before he could use it, and his research confiscated.
** Of course, the people that confiscated the research didn't ''stop'' the project, oh no. They discovered their own star was dying, renamed the project the Star ''Generator'', and used it in an attempt to save their planet. And apparently, no one expected the original mad scientist to get upset and try to take his ''weapon'' back...

* In ''Webcomic/SchlockMercenary'', a coalition of races pop and invade a DysonSphere made by the [[HigherTechSpecies Gatekeepers]]. The Gatekeepers blow up the sun in the centre of the sphere in response, almost wiping out the offenders in the process (it's no big loss for them. They've got more).

*** However, in the ''very'' far future (''many'' billions after ''many'' billions of years) the probabilities of a star passing so close to our Sun that planetary orbits will get disrupted increase. It has been estimated that after [[TimeAbyss a quadrillion (1,000,000,000,000,000) years]] our dead and dark Sun will have all of its planets stripped, so by then the Solar System will have ceased to exist. [[https://arxiv.org/abs/2009.07296 Newer estimations]], however, suggest this will happen much earlier, "just" roughly 100 billion years from now.

* In ''Literature/Zodiac2014'', [[spoiler:this is what Aquarius's plan would cause -- namely, going through the sun, which would shut it down completely. Note that while it's a horrible thing that the protagonists need to stop, it's only a ''side-effect'' if Aquarius's ''actual'' plan came to fruition.]]

* ''Manga/GalaxyExpress999'' has the metallic humanoids who blow up the Sun to eliminate the Earth because they hate and fear humans. Fortunately there are still many human colonies across the galaxy, and they are all ''extremely pissed''.

* ''Literature/TheLastHero'': Technically, the threat to the Literature/{{Discworld}} counts as this, although its sun (which is only a few miles in diameter) would've been a much smaller loss, as celestial bodies go, than Great A'Tuin and the world-bearing elephants.

Note that while it's a horrible thing that the protagonists need to stop, it's only a ''side-effect'' if Aquarius's ''actual'' plan came to fruition.]]

* ''Videogame/SimEarth'': At the end of the game, the sun expands and swallows up the planet.
* ''Videogame/StarRuler'' allows the player to blow up stars, with sufficient firepower. The star will go supernova, annihilating everything in the system - planets will be blasted apart, and any ship that can't outrun the explosion or jump away will be wiped away in a nuclear hellstorm.

* The plot of ''VideoGame/StarTrekBridgeCommander'' started and revolved around sun-shattering kabooms.
* {{Creator/Sierra}}'s ''VideoGame/SpaceQuest'' series has the Star Crusher, a (suprisingly small) energy weapon capable of vaporizing planets and detonating stars, thus theoretically capable of wiping out whole solar systems in one shot. Fortunately, the mad scientist who created it was exiled before he could use it, and his research confiscated.

-->Of course, I already knew a way to do that - I told you all about it on Day 6. The two ghost worlds I accidentally created, by colonising them with empty colony ships. I could do the same again here, and end up with an almost entirely empty world that still counts as an owned planet. It would be my almost-entirely-empty-world, of course, so I'd have to give it to the Terrans first - perhaps for a tidy price - then immediately destroy it to terrify them.

* ''VideoGame/FreeSpace2'' ends in the Shivans doing this to Capella... for reasons that [[ShrugOfGod have not been explained]].
* In ''VideoGame/StarCraftII'', a planet containing one of the Xel'Naga artifacts is being burned up from an expanding sun by the time Raynor's Raiders reaches it. Within a few hours, the sun will have engulfed it.

* ''VideoGame/XCom: Interceptor'' has the ultimate weapon as the Nova Bomb. When fired at a star, it takes about a minute to accelerate to light speed, at which point it is unstoppable. When it hits the sun, it instantly goes supernova, wiping out the entire solar system. You're ''supposed'' to use it to take out the alien superweapon, but there's very little preventing you from targeting a star the aliens have built several mining bases around and pulling the trigger. The star ''does'' in fact disappear from the map.

* ''VideoGame/ZoneOfTheEnders: The Second Runner'' features the military fortress Aumaan, which when activated, can radiate enough energy to swallow the entire solar system. [[spoiler:BigBad OmnicidalManiac Nohman attempts to do just this, but Dingo destroys Aumaan's core and destabilises the reaction before it does much damage. Beyond, y'know, destroying one of Mars' moons.]]
* The Pfhor in the ''VideoGame/{{Marathon}}'' Trilogy have a Trih Xeem in their arsenal, a [[{{Precursors}} Jjaro]] technology which roughly translates to "Early Nova". Guess what it does. They deploy it when they take heavy casualties or lose outright when waging wars and/or suppressing slave revolts. [[spoiler:Thing is, when [[MagnificentBastard Durandal]] and [[OneManArmy The Security Officer]] come along and spank them and cause them to unleash Trih Xeem, no one bothered to mention to them that the local sun was keeping a [[EldritchAbomination being of chaos]] imprisoned—the attempted X-2 cascades into an X-3 that The Officer [[MindScrew (Maybe)]] spends the final game trying to undo.]]

* In ''Webcomic/{{Sinfest}}'', [[http://www.sinfest.net/archive_page.php?comicID=2685 Slick claims that stars are civilizations blowing themselves up.]]
