Template:Articleissues In science fiction, a planet killer or Planet Buster (or some variation on that meaning) is an object capable of destroying an entire planet or rendering it uninhabitable.[1] One of the most notable examples of a planet killer is the Death Star from the Star Wars franchise or *The Doomsday Machine,seen in Star Trek.


Planet killers function in a variety of ways depending on the series. Weapons such as the Death Star and the titular ship in Lexx use a directed energy weapon capable of obliterating a planet in moments. In the game Spore, the planet killer is an antimatter bomb that is inserted in the center of the planet, causing the planet's center gravity to give away and split into countless little bits. Other weapons, such as the Shadow Planet Killer in Babylon 5 and Covenant warships in the Halo series, render a planet uninhabitable. The Shadow Planet Killer does so by firing missiles which burrow into the planet's core and detonate, causing planet-wide volcanic activity which renders the planet lifeless. Covenant warships use plasma weapons to superheat a planet's surface, called "glassing."

Some planet killers do not target the planet at all, but rather the star in the solar system. Nova bombs in Andromeda, the Sun Crusher in the Star Wars novels, and Dr. Tolian Soran's trilithium torpedo in Star Trek Generations are all capable of causing a supernova, obliterating every planet in the solar system.

Planet killers in fictionEdit


Film & TelevisionEdit


  • All Commonwealth warships were equipped with a limited stock of "Nova-bomb" warheads for their missiles, one of which is sufficient to cause a star to nova, thus destroying its planets.

Babylon 5Edit

  • Babylon 5: The Lost Tales - Centauri Superweapons, hinted at by a dream sequence set 30 years into the future that Sheridan experiences. While only NYC is destroyed in the scene, it is implied that all of Earth gets wiped out.
  • Shadow Planet Killer
  • Vorlon Planet Killer
  • Mass Drivers used by the Centauri against the Narn homeworld in the episode The Long, Twilight Struggle
  • Starships and orbital platforms were supposedly also capable of laying waste to a planet, such as the Shadow Battlecrab, a Minbari Sharlin Cruiser, the Narn-Drazi fleet that leveled Centauri Prime, and the Global Orbital platforms in Earth orbit.


  • The Lexx - Capable of entirely destroying planets.
  • The Foreshadow - predecessor of the Megashadow. Reduces the surface of Brunnis-2 into molten slag, using a large scale version of the "Black Pack" weapon often seen in the LEXX series.
  • The Megashadow - Annihilates an Ostral-B asteroid base and the surrounding field in a single shot.
  • Mantrid Drones

Stargate SG-1/Stargate AtlantisEdit

Although Stargate depicts a number of devastating technologies, few count as unreserved planet killers.

  • The Stargates themselves are composed of Naqahdah, and, if caused to detonate, would cause considerable damage.
    • Anubis's Ancient weapon that charges a Stargate powerfully enough that it explodes.
    • A wormhole passing through a star is capable of introducing super-heavy elements into it, thus destabilizing fusion processes and changing, possibly catastrophically, the climates of planets orbiting it.
    • P3W-451 has fallen into a black hole; an in-bound wormhole to its stargate propagates the gravitational influence back to the dialing gate. Initially this caused time distortion effects near the gate, but as P3W-451 got closer to the black hole objects were pulled into the gate, as of Exodus a gate dialing from a star would exert such a pull that it could not only remove matter from the star, but do so fast enough to cause it to go supernova. The effect of dialing from a planet at this point was not described.
  • A Mark 9 Naqahdah-enhanced nuclear weapon has a "Multi Gigaton" yield.
  • Anubis's mothership, powered with the Eye of Ra as well as four other "eyes", in "Full Circle"
  • The Dakara Superweapon in the Temple of Dakara can return all matter in its range to its base state, it is not powerful enough to destroy entire planets.
  • The Asgard managed to destroy Halla by causing Halla's sun to become a black hole.
  • The Ori Priors can turn planets into Point Singularities (Black Holes) to power their supergates, and have done so twice thus far.
  • The Replicators have spread across the surface of an entire planet and converted everything on it into replicator blocks.
  • A tainted Zero Point Module can explode with enough energy to destroy a portion of a solar system.[2]

Star WarsEdit

Other Film and TelevisionEdit

  • In John Carpenter's sci-fi film Dark Star, intelligent and philosophically capable "Exponential Thermostellar Bombs" are used to destroy "unstable planets" which might threaten future colonization.
  • In the Mel Brooks feature film spoof Spaceballs, the Spaceballs' starship, Spaceball One, is capable of transforming into "Mega Maid", a robot maid in the shape of The Statue of Liberty holding a giant vacuum cleaner, which can suck the air from an entire planet and thus make it uninhabitable.
  • In the film Chronicles of Riddick, the Necromongers cull potential recruits from planets and kill all those who remain on the surface by executing their "Final Protocol", a series of gravity-based weapons that flatten everything on the surface of the planet, save for the series of monuments that produce them.
  • Hugo Drax's space station in Moonraker, which launches poisonous globes that would have wiped out mankind.
  • The Pirate Planet in Doctor Who. Additionally, the Daleks and TARDISes have both been shown to be capable of moving planets, and would thus be capable of relocating a planet into a star, nova, black hole, or other inhospitable location that would destroy it. Daleks have also been stated to have been responsible for the destruction of The Doctor's home planet of Gallifrey, though at other points in the series the impression is given that the world has, rather, been removed from reality. In Planet of the Dead, the Swarm is shown to annihilate all life on a planet's surface. In The End of the World, technology is shown holding the Earth together and preventing the sun from exploding, and thus the Earth is destroyed simply by deactivating this technology. In various episodes, The Doctor and his companions manage to stop threats that would destroy the Earth or other planets, with the indication that those threats are valid.
  • "Q Bomb" from Starship Troopers 3: Marauder
  • Unicron, a robotic predatory planet from the animated feature film, Transformers: The Movie.

  • In the TV series Earth Final Conflict, the Jaridians have a planet killer and have destroyed thousands of Taelon-occupied planets including their homeworld. The video archive of all the planets destroyed one after another is seen by William Boone but at the time he doesn't understand what it is until the circumstances are explained to him later by Da'an.
  • In the TV series Andromeda, point singularity weapons, nova bombs, Maximm charges, and in rare cases, kinetic missiles, are used to destroy planets.

  • The Illudium PU-36 Explosive Space Modulator In the classic Bugs Bunny short Haredevil Hare in 1948. Marvin Martian wanted to use it to blow up Earth because, as he said, "It obstructs my view of Venus". The explosive was in the form of a small red stick that resembled Dynamite that was screwed into a large telescope-like machine.

Literature Edit

Dune UniverseEdit

The Hitchhiker's Guide to the GalaxyEdit

  • Vogon Constructor Fleets

Vogon civil services are not only able to demolish entire planets, but have means and cause to do so regularly (to create and maintain hyperspace by-passes). The Earth falls victim to one such fleet in the beginning of the story to make way for a hyperspace expressway.

The radio and book versions of the story refer to demolition beams, though the mechanism is not shown distinctly in the 2005 film.

There is also the ultimate weapon designed by Haktar a giant space bourn computer. It's a very small bomb that when activated will join the heart of every major sun with the heart of every other major sun turning the universe into one gigantic hyperspacial supernova. The weapon was designed for a race of extinct aliens but was taken up again by the inhabitants of the planet Kricket so as to wipe out all other life in the universe and permit them to be the only inhabitants of the universe.

Other LiteratureEdit

  • The Inhibitor machines from Alastair Reynolds' Inhibitor series of novels, were capable of consuming worlds over time to convert to copies of themselves, or to create weapons capable of utilizing stars to destroy planets e.g. venting stellar core material in a collimated beam to burn away planetary crusts. In the same series, the "Greenfly" machines, developed by humans as terraformers, instead go rogue and start eating planets by reducing them to their atoms and rebuilding them into more such machines, as well as numerous domes filled with vegetation.
  • Spacer nuclear reaction intensifier (Robots and Empire)
  • Stephen Baxter's Moonseed: a virus-like microscopic object (or substance made from it) that transforms substances into more copies of itself - and thus consumes Venus and then the Earth by doing so. (Baxter has also employed geomagnetic storms (see Sunstorm) and larger universal constructors (see Evolution) as planet killers.)
  • The glass clock built in Terry Pratchett's Discworld novel Thief of Time, was effectively a doomsday device. Although its intended effect was to permanently freeze time on an entire world, rather than outright destroying it.
  • The Neutronium Alchemist (Peter F. Hamilton's The Night's Dawn Trilogy)
  • At least five methods in E. E. "Doc" Smith's Lensman saga: "super-atomic bombs"; a "nutcracker", consisting of crushing a planet between two others; a "negasphere," an antimatter planet; "Nth space planets" from other dimensions which travel at superluminal speeds can be used to ram planets or even create supernovas - there was even the worrying possibility that these could cause the Big Crunch in zero time; and a "sunbeam", a way of concentrating most of a sun's energy output into a narrow beam -- this one a defensive-only weapon against nutcrackers and negaspheres.
  • Device Ultimate in The Xenocide Mission
  • In Kevin J. Anderson's Saga of the seven suns, the ongoing war between the Faeros and Hydrogues see entire suns having their cores frozen.
  • In Orson Scott Card's Ender's Game, the MD (Molecular Disruption) Device, or "Little Doctor", generates a field inside in which it is impossible for atoms to coexist in a molecule. The field propagates in a chain reaction, and essentially destroys all matter until it reaches pure space. This was intended for ship to ship combat, but was eventually used to destroy an entire planet.
  • In E. E. Smith's Skylark of Space series various planet-killers are used or discussed. Throwing planets and moons out of orbit, incredibly high-yield atomic or copper bombs, near-instantaneous dematerialization of physical objects and the teleporting of close to fifty billion stars in order to wipe out a Galaxy-wide alien civilization are all used.
  • In L. Ron Hubbard's Battlefield Earth a device is created which, when activated, causes all matter it touches to break down into its constituent molecules. This device was used on a moon, which was consumed faster than ships based on that moon could launch.
  • In the Gor-novel series by John Norman, specifically "Tribesmen of Gor", the alien Kurrii deploy a weapon, apparently housed in a small space craft, to the eponymous planet. If it had been put to use, it would have to have rendered the planet uninhabitable not only to humans, but also to the Priest-Kings, who were sheltered deep inside a mountain range.
  • Nova Bombs (Starship Troopers)
  • Relativistic projectiles (Charles Pellegrino and George Zebrowski's The Killing Star)
  • The Electron Pump (Isaac Asimov's The Gods Themselves)
  • The Dahak-class Planetoid-of-the-Line (David Weber's Heirs of Empire trilogy)
  • The Supernova (Matthew Reilly's Temple)
  • Arkon-Bombs from the Perry Rhodan Books "ignite" all matter near it to burn away in a fission like effect. This can not be stopped but it is not very fast, giving the chance to evacuate the planet.
  • Ice-nine on the novel Cat's Cradle by Kurt Vonnegut. The ice-nine is a solid form of water at ambient temperature. It causes the end of the earth when some of it falls into the ocean, causing a chain reaction that transforms all the water on Earth into ice-nine.
  • Quark bombs in the novel Lord from the Planet Earth by Sergei Lukianenko. A group of radical cultists from another planet wanted to destroy Earth with a quark bomb, but are foiled by the protagonists.


Halo seriesEdit

  • UNSC NOVA Bomb (a group of nukes clustered around a core that forces the fissionable material together, magnifying the explosion)
  • Covenant Warships (starships equipped with plasma weapons used to vitrify the surface of a planet)

The Halo installations themselves only kill sentient life, leaving planets and their biospheres-as well as any creature without sufficient biomass to support The Flood-otherwise intact.

According to in-game details, the Nova Bomb slowly accelerates to light speed and burrows itself into the core, causing the star to go supernova, completely destroying the whole system. After the Doomsday Weapon built by the aliens is located (on the other side of a black hole), the player is told that it can only be destroyed with a Nova Bomb. The technology was considered so dangerous the scientific community asked for all knowledge of the bomb to be stricken from records so it would not fall into the wrong hands.

Anime & MangaEdit

Dragonball ZEdit

Many characters including Goku, Gohan, Vegeta, Piccolo, Trunks, Buu, Majin Buu, Kid Buu, Cell and Freeza have obtained strength through rigorous training and bloodline to suffice the power necessary to be a planet killer using ki energy.

Kiddy GradeEdit

  • Geo-Sort technology has the ability to reconfigure large amounts of matter at the molecular level; thus it can not only destroy entire planets, but make hostile planets habitable through terraforming.
  • The Deucalion presumably has this capability as well, since it is outfitted with Geo-Sort technology (but this is never demonstrated in the series).

Sailor MoonEdit

One of the Outer Senshi, Sailor Saturn, can destroy an entire planet by using her weapon (the Silence Glaive) and the attack "Death Reborn Revolution".

Gall ForceEdit

In the final battle with Kain, who is apparently powerful enough to destroy a planet on his own. Washu decides to have Kiyone make use of a "Dimensional Cannon". In spite of Kiyone's protests that you shouldn't even use it on a city because it's made for taking out small galaxies. That's planet killing on a massive scale.
