* ''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.

* Normally, the card game ''NuclearWar'' only goes so far as allowing players to irradiate the planet in a Class 3 or Class 4 situation. However, the rules state that if a player launches a 100-megaton warhead and spins the (improbable) "Hit nuclear stockpile" result, the game instantly ends as a chain reaction engulfs the planet and ''the entire solar system'' in a nuclear fireball.
* In the RPG ''{{Traveller}}'', the Darrians have a weapon that can send a star supernova.

* The [[AllThereInTheManual backstory]] of the Franchise/{{Halo}} universe states that the [[{{Precursors}} Forerunners]] deliberately did this several times in ([[ShaggyDogStory failed]]) attempts to stop the spread of [[TheVirus the]] [[PrecursorKillers Flood]].

* The final {{Kamehameha|doken}} Cell of ''DragonBall Z'' 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.

* ''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''.

* As revealed in Part 2 of ''FanFic/ClashOfTheElements'', [[spoiler:A Class X-2 Apocalypse happened long ago when the [[KingdomHearts Realm of Darkness]] started to overtake the real universe, taking many planets and stars into itself before it was stopped.]]

* One of the [[IHaveManyNames many names]] of the [[{{Satan}} Lone Power]] from the ''YoungWizards'' series is "Star Snuffer", since It has the ability to both render a star dark and cause it go supernova.

Star System-scale Physical Annihilation. You know that big ball of hydrogen/helium fusion and the bunch of rocks that used to circle it? Yeah, [[StarKilling they ain't here no mo']]. This usually happens due to that particular fusion ball doing something unpleasant like going supernova.

* Creator/AlanDeanFoster's ''HumanxCommonwealth'' series novel ''The End of the Matter'' is about a rogue Black Hole that threatens multiple star systems by devouring their suns, leaving them barren and lifeless. The protagonists spend their time looking for a LostSuperweapon reputed to have been developed by an ancient race specifically for use against this type of threat.

* When Cell of ''DragonBall Z'' launches his final {{Kamehameha|doken}}, he claims it 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 an 11 year-old kid.]]

* Magazine/NationalGeographic progam, ''Evacuate Earth'' (Evacuation Earth) , has this kind of sitaution with a rogue neutron star, [[http://channel.nationalgeographic.com/channel/videos/god-help-us/ not only destorying Earth]] but other plants in the solar system, possibly the sun as well.

* ''{{SimEarth}}'': At the end of the game, the sun expands and swallows up the planet.
* ''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.

* In ''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...]]

* In one ''ComicBook/{{Superman}}'' story during TheSilverAgeOfComicBooks, Superman inhaled all the sneezing powder Mister Mxyzptlk was sprinkling all over Metropolis, which forced him to quickly fly to a dead and desolate solar system and annihilate it with a single sneeze.

* In ''TheDarkPhoenixSaga'', Dark Phoenix recharges herself by consuming the D'Bari sun, causing it to go supernova and annihilating a planet of five billion people.

* In one ''ComicBook/{{Superman}}'' story during TheSilverAgeOfComicBooks, Superman inhaled all the sneezing powder Mister Mxyzptlk was sprinkling all over Metropolis, which caused him to quickly fly to a dead and desolate solar system and annihilate it with a single sneeze.

** While our sun's red giant phase will destroy the inner planets by swallowing them, those planets that won't be swallowed (which includes all the gas giants) will survive quite well so this won't be quite an X-2. Plus the sun will still be there as a white dwarf.

* ''[[Series/BattlestarGalacticaReimagined Battlestar Galactica]]'', believing that ''fifteen'' known cases of Class 2 by the middle of the third season was not enough, gave us a supernova at the end of "Rapture". This was a natural event... maybe.

* ''GallForce'' featured the System Cannon, a WaveMotionGun disguised as a Planet. Its primary purpose was, after the enemy was lured into its system, to would fire at its own star, blowing the entire system to space dust. Considering that its destruction formed our Asteroid Belt, perhaps it's for the best that it didn't hit the target.

* ''GalacticCivilizations II'' includes, in one of the expansion packs, the Terror Star: a [[DoesThisRemindYouOfAnything moon-sized space station]]:

* NationalGeographic progam, ''Evacuate Earth'' (Evacuation Earth) , has this kind of sitaution with a rogue neutron star, [[http://channel.nationalgeographic.com/channel/videos/god-help-us/ not only destorying Earth]] but other plants in the solar system, possibly the sun as well.

* ''{{Freespace}} 2'' ends in the Shivans doing this to Capella... for reasons that [[ShrugOfGod have not been explained]].

* In ''QuentynQuinnSpaceRanger'', when the Kvrk-chk ate a Racconan colony ship's passengers and broadcast that they would come after the rest next, the Empire retaliated by roasting one of the more populated Kvrk-chk star systems with a stellar lance.

* In ''{{Sinfest}}'', [[http://www.sinfest.net/archive_page.php?comicID=2685 Slick claims that stars are civilizations blowing themselves up.]]
* In ''{{Homestuck}}'', The Tumor is a bomb that can destroy the Incipisphere (a pocket dimension roughly with the size and contents of a solar system) [[spoiler:and is designed to do so to erase Null Sessions]]. [[spoiler:[[BigBad Jack Noir]]]] would have eventually destroyed the Kids' Session via a bunch of Class Xs, [[spoiler:and ends up doing this to the Trolls' Session]].

* ''Franchise/FinalFantasy: [[VideoGame/FinalFantasyEndlessNova Endless Nova]]'' revolves around this. [[spoiler: It turns out Paradorn has been pulling off Class X-4s on a regular basis, just to feed herself. Apparently she can use magic to turn a supernova into a universe-wide disaster.]]
* The plot of ''StarTrekBridgeCommander'' started and revolved around sun-shattering kabooms.
* {{Sierra}}'s ''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.

* The StarWarsExpandedUniverse featured some pretty badass weapons, ridiculous as they were, including the Sun Crusher (which caused a sun 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 was 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.
