History Main / StarKilling

* In Christopher Ruocchio's ''Literature/TheSunEater'', the glossary of the series mentions that there was a historical event during the Crusade where the Gododdin system was destroyed by protagonist Hadrian Marlowe. ''Howling Dark'', the 2nd book of the series, has a character Suzuha give Hadrian some information about her famous father Kharn Sagara. She mentioned that in the distant past humanity created A.I. and it reached a point where they far exceeded human intelligence. The A.I. created star killing weapons far beyond human capacity - weapons that created cold, weapons that actually destroyed matter and weapons that tore the fabric of reality. Her father Sagara, liberated humanity and is the sole keeper of these weapons.

* ''WesternAnimation/MightyOrbots'': In the final episode, SHADOW had developed a new weapon called the Sun Smasher which they used once to show it lived up to its name. This would be SHADOW and Umbra's undoing as Mighty Orbots was able to cause the Sun Smasher to backfire and blow up the star system that Umbra is housed in.

* In ''Manga/Toriko'', there were legends of a "Demon King" that would someday eat the sun. While such a creature turned out to not actually exist (at least not in that form), the Appetite Demon NEO was a threat to the world and the entire universe.

* ''Literature/SpaceAcademyDropouts'': The purpose of the SKAMM missiles is to trigger supernovas in healthy yellow stars within a matter of hours.

* In the ''VideoGame/SpaceEmpires'' series, blowing up a star destroys everything in the system. If that's not enough, [[UpToEleven you can turn it into a black hole]], which also destroys the raw materials you can use to [[GenesisEffect recreate planets]].

** It's been previously established that going to warp inside a solar system is a high-risk move, and reiterated within the episode itself (Kira only does it because [[GodzillaThreshold if they don't, there won't be a solar system left]].) Some novels seem to indicate that activating a warp engine too close to a star can cause serious problems for the star, which also falls under this trope, so....

* A novel by Barrington J. Bayley included a weapon which worked by eliminating all of the electrons in a star, thereby rendering fusion impossible. A star hit by the weapon would lose about 0.05% of its mass and instantly go out. In RealLife, making the electrons spontaneously disappear without something else changing as well would cause the star to blow itself apart due to the immense repulsion between the protons.
%% The 0.05% was formerly 1/1400. If that was the book's theory, it should probably stay.

* ''VideoGame/StarTrekOnline'' reveals that the Hobus supernova that destroyed Romulus and Remus in 2387 was caused deliberately by a rogue faction of the Romulan [[StateSec Tal Shiar]] acting in service to the [[AbusivePrecursors Iconians]]. The nature of the weapon used caused the shockwave to propagate through subspace, reaching the Romulan system in a mere 27 hours. (This is the game's way of explaining the [[SciFiWritersHaveNoSenseOfScale completely nonsensical]] destruction of Romulus in ''Film/StarTrek2009''.)

* In the backstory of ''VideoGame/StarControlII'', the Shofixti [[HeroicSacrifice blew up their own sun]] to stop the advancing Ur-Quan fleet. It was a futile effort, though; while the Ur-Quan lost about a third of their fleet, they still won the war while the Shofixti were effectively driven extinct. [[spoiler:It is possible to repopulate them, however, much to the delight of the last surviving male.]] Later, a similar bomb is used to destroy the Ur-Quan [[TheMothership Sa-Matra]].

* In Christopher Ruocchio's ''The Suneater'', the glossary of the series mentions that there was a historical event during the Crusade where the Gododdin system was destroyed by protagonist Hadrian Marlowe. ''Howling Dark'', the 2nd book of the series, has a character Suzuha give Hadrian some information about her famous father Kharn Sagara.

Her father Sagara, liberated humanity and is the sole keeper of these weapons.

* In the ''Franchise/GreenLantern'' instalment of ''ComicBook/FinalNight'', the Sun-Eater was killing Earth's sun, Hal Jordan does a HeroicSacrifice that saves it and restores the damage. In the process, it shone green for a day.

'''Human:''' ''[[ShutUpHannibal Once.]]''

So you've got a star. Main sequence type, more or less middle of its life-cycle, nothing special. Probably has an inhabited planet or two orbiting it. Of course, the Evil ([[RecycledInSpace Space!]]) [[EvilEmpire Empire]] wants the people on the planet(s) dead. They ''could'' just carpet bomb the planet or maybe [[EarthShatteringKaboom even blow it up]], but instead they decide to go for broke. When a faction or character goes StarKilling they go about ending a star's life in any of a variety of ways that dooms all life in the system to a ApocalypseHow/ClassX2 ApocalypseHow.

* ''Webcomic/KillSixBillionDemons'': If Incubus and Solomon David are to be believed (the former is a liar, the latter usually too proud to lie), the Demiurges are able to use their powers to destroy or steal suns. Solomon also moved and/or created a pair of suns to replace one that was destroyed.

Interesting: even though immediate aging of a star is extremely unlikely, it is theoretically possible to increase the speed of a normal star's aging. Usually, most matter within a star is a hydrogen/helium mixture, and most of the star's life cycle it burns hydrogen into helium. However, a tiny part of the star's mass consists of carbon-nitrogen-oxygen, which transform into each other through the CNO cycle, catalyzing (i.e. accelerating) the burning of hydrogen. So, dump enough carbon or nitrogen[[note]]Not ordinary oxygen. Any time O16 appears in its ground state, that particular participant in the CNO cycle ends.[[/note]] into an average star[[note]]The CNO cycle won't run at all if the star isn't massive enough to trigger catalyzed fusion in its core. It takes at least 1.3 solar masses for the CNO cycle to become its dominant energy source. The prime candidates for adding carbon or nitrogen would be massive, old stars that formed before the interstellar medium became enriched with heavy elements.[[/note]] and it probably will age faster AND burn hotter.[[note]]That may be the natural conclusion, but in RealLife, [[RealityIsUnrealistic the opposite would happen]]. Upon the initial boost in fusion, the star would expand, slowing down the fusion reaction. Gravity would be weaker as well. A new stable equilibrium would be reached where fusion would occur at the slower rate sufficient to balance the weaker gravity. Stellar fusion would slow down.[[/note]] The effect won't be immediate, though. The mixing of star matter is slow, and distribution of additions will take many years, maybe even ages.

* ''Comicbook/{{Excalibur}}'' #50 has [[CosmicEntity Phoenix]] and and [[BigBad Necrom]] in a rapidly-escalating battle in Space that starts by throwing asteroids at each other, but they're destroying stars. Phoenix realizes that at the rate things are escalating, it won't be long before they [[ApocalypseHow destroy the universe]], so instead she allows Necrom to absorb her power and thus kills him via PhlebotinumOverload.
* In the ''Franchise/GreenLantern'' installment of ''ComicBook/FinalNight'', the Sun-Eater was killing Earth's sun, Hal Jordan does a HeroicSacrifice that saves it and restores the damage. In the process, it shone green for a day.

* In ''Videogame/Destiny2'', the invading Cabal Empire deploy a massive starship known as the Almighty to prepare to destroy Earth's Sun. It's said that the Red Legion, the fleet that has invaded the Solar System, makes it a policy to destroy the sun of a star system once they've finished conquering all resistance and [[PlanetLooters stripped the system of all useful resources]], to seal their victory and remind everyone else they fight of the price for resistance. The player Guardian eventually has to sabotage and destroy the Almighty, since without it being taken out any victory elsewhere against the Cabal is meaningless.

* The "Star Harvester" from ''Film/TransformersRevengeOfTheFallen''. [[BigBad The Fallen]] wants to use it so he can destroy the entire Solar System.
