List of planet killers
In science fiction, a planet killer, planet buster, or similar variations on that meaning, is a fictional object or device capable of either destroying an entire planet or otherwise rendering it uninhabitable – a variety of a doomsday device. Examples of such devices include the Death Star from the Star Wars film franchise, the "Doomsday Machine" seen in the original Star Trek television series or the atomic-powered stone burners from Frank Herbert's Dune books.

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 core to split into countless fragments. 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 the surface of the planet; the crust is turned into a glass-like substance rendering it uninhabitable. In Star Blazers, missiles that can destroy a planet (and even a star) with a single hit exist.
Some devices can destroy entire star systems. Nova bombs in Andromeda, the Sun Crusher and Centerpoint Station 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 fiction
Film and television
- 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 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 – They consume all forms of matter (including planets) to replicate themselves.
- In Justice League: Crisis on Two Earths, the Quantum Eigenstate Device (QED) is a planet-killing or possibly universe-killing weapon.
- Most cosmic beings and even some heroes or villains have the power to destroy a planet.
Stargate SG-1/Stargate Atlantis
- A tainted Zero Point Module can explode with enough energy to destroy a portion of a solar system.
- Project Arcturus, an abandoned Ancient project capable of extracting energy from our own universe, unlike a normal Zero Point Module which draws energy from subspace, would create exotic particles with unpredictable properties, and would overload to actually destroy approximately 5/6 of a solar system.
- 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 inbound 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.
- The Dakara Superweapon in the Temple of Dakara can return all matter in its range to its component molecules. Its range is normally limited to Dakara and its surrounding space, however the wave will propagate through the wormhole of an active Stargate (unimpeded by either iris or Goa'uld shield technology) and expand on the far side to cover the planet's surface, but unlike Dakara itself, the wave will not propagate into orbit. Ba'al however modified the Dakara Stargate, using a 'hack' of the DHD's correlative update function to dial every Stargate in the Galaxy simultaneously, turning the weapon from a strategic threat to a Galactic scale superweapon against all planets within the Milky way Stargate network.
- A Tauri Mark 9 Naqahdah-enhanced nuclear weapon has a "Multi Gigaton" yield.

It was also capable of using these devices to reduce ships and space stations into digital patterns, destroying the originals in the process.
- Genesis Device (a terraforming project; not really intended as a weapon but if used against an existing biosphere it will destroy it in favor of a new one)
- Reman warbird Scimitar: Emits a specific type of "thalaron" radiation that will kill every living thing on a planet in seconds
- Son'a collector (intended to strip radiation surrounding a planet thus rendering it uninhabitable)
- Trilithium torpedo. Used by Dr. Tolian Soran in Star Trek Generations to stop all the fusion reactions in a star, causing it to go nova, much like the Tox Uthat.
- Red Matter. A material capable of creating black holes. It could be used as a planet-killer by being injected into a planet's core, creating a black hole that imploded the planet by consuming it from the core outward. Red Matter is also potentially strong enough to consume a star. An example of a ship that used this is Spock's ship, the Jellyfish. The Narada also used the supply on Spock's ship when they captured it. (Star Trek (2009)).

- The Pirate Planet materializes around other planets, destroying them.
- Additionally, the Daleks and Time Lords 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. Image of the Fendahl reveals the Time Lords trapped the world of the Fendahl, 5th planet of the Solar System, in a time loop. In The Trial of a Time Lord it is revealed the Time Lords devastated Earth with a fireball and moved it two light years around 2,000,000 AD. Daleks have also been stated to have been responsible for the destruction of The Doctor's home planet of Gallifrey, planet of the Time Lords, though at other points in the series the impression is given that the world has, rather, been removed from reality. It is later claimed the Doctor destroyed his world to end the Time War using 'The Moment', thinking it would destroy the Daleks. The Daleks have shown themselves to be capable of destroying planets; in "Asylum of the Daleks" they destroy the Dalek Asylum with an attack from space. in The Daleks' Master Plan the First Doctor uses their weapon, the Time Destructor, against them, turning the jungle planet of Kembel into a desert. In "Journey's End" Davros and the Daleks attempt to destroy all Universes with the Reality Bomb, which breaks down matter and is transmitted using stolen planets that include Earth.

- The Hand of Omega in the TV series Doctor Who can be used to destroy planets by manipulating stars, as demonstrated on the Dalek homeworld Skaro.
- The Osterhagen Key detonates 25 nuclear weapons under strategic points in the Earth's crust, causing it to rip apart (But to only be used if) "Humanity were suffering unbearably, with no hope or help ever coming.." in "The Stolen Earth" and "Journey's End" on Doctor Who.
- The Tenth Planet, set in 1986, features the Z-Bomb, a weapon that could destroy the Earth, at a North Pole base. There are apparently others at strategic positions around the world. The General commanding the base tries to use it to destroy the planet Mondas, while its inhabitants the Cybermen try to use it to destroy Earth as Mondas is absorbing too much energy from Earth, which eventually destroys it.
- In The Dominators the villains of the title try to destroy the peaceful planet Dulkis, as a fuel source for their fleet, by sending a seed device into the planet's core.

- In the science fiction feature film Men in Black II, Serlena's ship is seen making vengeful blasts on searched planets, causing an icy one to shatter and another to implode.
- The Displacement Engine in the TV series Farscape is a device which employs a wormhole to draw a large mass of fusing plasma from the core of a star, and then deploys it against a target. The device is described as being able to destroy a solar system.
- A major plot of the series Farscape is that the knowledge of wormholes contained in the head of John Crichton can be used to create a planet-killing weapon; in Farscape: The Peacekeeper Wars Crichton finally builds and activates such a weapon to show that it is much worse; it is in fact a galaxy-killer. Under threat of everyone being consumed by the weapon, he convinces the Peacekeepers and Scarrans to pursue peace negotiations in return for him turning it off.
- In the German TV series Raumpatrouille, a weapon called Overkill was used to destroy an object the size of a planetoid. The explosion seems to be strong enough to destroy a planet as well.

- The Illudium PU-36 Explosive Space Modulator In the classic Bugs Bunny short Haredevil Hare in 1948. Marvin the 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.
- The 'Sun Harvester' in Transformers: Revenge of the Fallen. This is hidden inside one of the pyramids in Egypt and uses the Matrix to power up, destroying the sun to turn it into energon.
- In the Tokusatsu Kaiju Film Ghidorah, The Three-Headed Monster, King Ghidorah attacked Venus (Mars on the English dub), leaving the planet uninhabitable. A variant version of King Ghidorah from the Rebirth of Mothra film trilogy sees the creature wiping out all dinosaurs on Earth, effectively acting as a Planet Killer in this respect, though life returns to the planet, and is eventually dominated by humanity. King Ghidorah. like Unicron (listed above), stands out from others on this list for being a living creature, something few other planet killers on this list have in common with it.
- In the British Sci-Fi series Space: 1999 Season Two opening episode- THE METAMORPH, Commander Koening orders General Order Four, which Tony Verdeschi reveals is "a coded signal to destroy the place it originated from".

The Hitchhiker's Guide to the Galaxy
- 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 Hactar (a giant space-borne computer). It is 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 hyperspatial supernova. The weapon was designed for a race of extinct aliens but was taken up again by the inhabitants of the planet Krikkit so as to wipe out all other life in the universe and permit them to be the only remaining inhabitants. Also, the Krikkit Battleclubs can destroy major suns with their hypernuclear grenades.
Lastly, although not typically considered part of the main five-book trilogy, the short story Young Zaphod Plays It Safe mentions Zaphod passing by the doors of rooms filled with chemical and other agents that could sterilize, irradiate, explode, et cetera a planet; he then remarks that he is therefore glad he is not a planet.
- The Inhibitor machines from Alastair Reynolds' Revelation Space 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.
- The Spacer nuclear reaction intensifier in Isaac Asimov's Robots and Empire (1985)
- 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.)
- In Stephen Baxter's Xeelee Sequence, the Xelee have a handgun-sized weapon capable of destroying stars and neutron stars. Also, during their final war with humanity from 700,000ad, the Xeelee built giant dyson shells around every single star in the Milky way, this forces the human inhabitants of the worlds to flee as the planets freeze.
- 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)
- Quantumbusters in Peter F. Hamilton's Commonwealth Saga
- At least six methods in E. E. "Doc" Smith's Lensman saga:
- "super-atomic bombs"
- rendering a planet "loose" (inertialess) and directing it into a star
- a "nutcracker", maneuvering two loose planets to crush a third
- a "negasphere," an antimatter planet
- "Nth space planets" from other dimensions which travel at superluminal speeds and can be used to ram planets or stars (creating supernovas) – there was even the worrying possibility that these could cause the Big Crunch in zero time
- 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
- Of these, the Nth-space planet is considered the most lethal as its speed and inter-dimensional nature leaves no means to defend against it; this knowledge precipitates the final battle in Children of the Lens.

- 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 Daniel Edward's Division, planet-eaters focus gravity onto a planet, ripping it apart. This technology is used on Earth, destroying it utterly. Several other planet killers are mentioned
- In E. E. Smith's The 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.

- L. Ron Hubbard's Battlefield Earth (1982) features a device 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 Kurii 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). Not precisely a weapon per se; the destruction it produces is a side effect (albeit one the creators are aware of and consider acceptable, since it will also produce a great deal of usable energy).
- The Dahak-class Planetoid-of-the-Line (David Weber's Heirs of Empire trilogy)
- Two of David Weber's books; The Armageddon Inheritance, and The Shiva Option, feature inhabited planets biospheres destroyed by the impact of asteroids or moons on deliberately modified intersecting orbits.
- Throughout David Weber's Honorverse series just about any warship has the potential to wipe out all higher life on a planet by kinetic bombardment and this has happened in the past.
- S.T.A.R Platforms (The Blank Horizon), originally used for faster than light communication by artificially generating a molecule-sized wormhole, are capable of focusing over 1000 km square of a stars surface output into a beam a little over 2 cm wide, reaching temperatures in excess of 4.2 billion degrees, which could theoretically cut a planet apart and combust its atmosphere. This is never put into practice however, as the platforms are self-destructed to prevent them from being captured and used against their creators.
- In the Looking Glass series by John Ringo and Travis S. Taylor, the alien Dreen possess an explosive powerful enough to destroy planets, and the alien black box starship drive will generate a field capable of destroying entire star systems if exposed to high voltage electricity.
- The Demolio is a bomb which can shatter planets in Brian Herbert's Timeweb Chronicles.
- The Supernova (Matthew Reilly's Temple) - A weapon based off a fictional radioactive element. The weapon was described to be able to destroy a third of the mass of the planet. The element used as the core of the device is only found, rarely, in meteorites - only one active sample has ever been found and is being pursued by the American military and several terrorist organizations.
- 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 in the novel Cat's Cradle by Kurt Vonnegut 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.

- In M. Andrew Sprong's book Haley Cork and the Blue Door two forms of planet killers are employed. In one case the Enemy uses an anti-mercury bomb to destroy half of the planet's population in order to blind the sensors of its guardian moon. In another, Haley, as a personified biomechanical weapon, teleports billions of copies of herself using quantum foam technology to the same exact location in order to convert herself into a blackhole and destroy the Enemy's planetary armada.
- The Berserker series is a series of space opera science fiction short stories and novels by Fred Saberhagen, in which robotic self-replicating machines intend to destroy all life. These Berserkers, named after the human berserker warriors of Norse legend, are doomsday weapons left over from an interstellar war between two races of extraterrestrials.
- 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 (commonly called glassing) 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.
- Motherships are stated to instantly destroy entire planets
- Most larger warcraft have purification beams, which easily crack open planets and let the magma do the rest of the work
- Bombardment with apocalypse class nukes, FTL-capable nukes meant to be launched en-masse. 1000 is extreme overkill for wiping out all life on a fortified planet, with explosions easily visible from orbit

- Atmospheric deprivation missiles in Homeworld are used by the Taiidan (or Kushan, depending on the player's choice of race), while (unknown to them) the Mothership was held up by raiders on the outskirts of the system. Afterwards, the northern hemisphere was blackened and fires were visible from high orbit. In Homeworld 2, the main antagonists (the Vaygr) attempt to use similar technology in the final mission – one of the mission's objectives is to intercept the missiles before they reach their target. However, the planet is not 'killed' after one missile strike; each missile kills approximately half of the current surviving population, and the mission is failed if too many slip by (it takes approximately 5 to fully depopulate the planet). The T-MAT Motherships and the Progenitor ship, the Sajuuk, are also considered as Planet Killers.
- Black Sun (Supreme Commander), an extremely powerful laser weapon that utilizes a gate network to target and burn multiple planets in a single firing. Fired from the Black Sun facility located in Hawaii.
- Mechanoid motherships (Rifts)
- Jenova in Final Fantasy VII, a parasitic being which drains life from any planet that it lands on. Described by Vincent Valentine as being "Heaven's Dark Arbiter."
- Meteor (Final Fantasy VII); it should be noted that the intention of its caller in the game required the Planet to survive.
- Shivan Juggernaut Sathanas could, as a group, create a gigantic ripple in the subspace field surrounding a star, causing the star to become unstable and go nova, ostensibily destroying all planets in the system.(FreeSpace 2)
- Shivan Super Destroyer Lucifer used three "flux cannons", which are more popularly known as "beams", to obilterate the surface of an entire planet, rendering it invulnerable. However, in the cutscene, the Lucifer used only one, which could release an expansive blast which could burn away a small fraction of a planet. (Descent: FreeSpace — The Great War)
- Star Generator (Space Quest 1)
- Stellar Converters (Master of Orion II: Battle at Antares), plasma cannons of immense size and power that are capable of tearing straight through virtually anything in the line of fire.
- The Kilrathi Dreadnought Sivar (Wing Commander: The Secret Missions) - This warship designed by the Kilrathi carried with it the Graviton Weapon, which could destroy a planet and all life on its surface by increasing its gravitational field 137 times the normal force.
- TCS Behemoth and the Temblor Bomb (Wing Commander III) - The TCS Behemoth was a super-heavy dreadnought which carried a superlaser capable of obliterating any target ranging from a starship to a planet. The latter weapon, the Temblor Bomb was designed to exploit the instability of a planet's fault line to trigger a super earthquake that would subsequently destabilize a world's entire tectonic makeup, literally shaking it apart to the point of implosion. The Temblor Bomb could only be launched via starfighter, and the player must destroy the Kilrathi homeworld of Kilrah by this means.
- Terror Star, a parody of the Death Star (although a fully functional star killer) from Galactic Civilizations
- The "Iron Helix" (used to destroy Calliope if you fail the mission)
- The "Nova Bomb" in X-COM: Interceptor – this was a missile carried on fighters which, rather than being used against a planet directly, was fired at the star inside the system. 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.

- The Alphacore (Omega Boost)
- The Ancient Planetary Bombardment Platforms (Homeworld 2)
- The Biologic Space Labs research station in Metroid Fusion (Game Boy Advance) is equipped with a self-destruct system capable of destroying a planet within its blast radius. In addition, the planet Zebes was equipped with a planetary self-destruct mechanism in Super Metroid (Super Nintendo Entertainment System)
- The Black Egg and Mulligan artifacts (Starflight)
- The Crest of Annihilation (Star Ocean: The Second Story) (this device completely obliterates a planet, but it is allegedly powerful enough to wipe out the entire known universe)
- The Death Egg from Sonic the Hedgehog 2 and Sonic & Knuckles, a parody of the Death Star and a caricature of Dr. Robotnik. Armed with two ion cannons (supposedly) forming the "eyes" on the "face", it is damaged and repaired throughout the early Sonic the Hedgehog series.
- The Sa-Matra from Star Control 2.
- The Galactic Implosion Device (Total Annihilation)
- The 'PlanetBuster Maximus' in the video game Ratchet & Clank, a skyscraper-sized bomb "capable of reducing an entire planet to subatomic particles". There was another device named 'The DePlanetizer', referred to as "The most powerful laser ever invented". It consisted of a giant football field-sized platform with a large rotating laser cannon on the bottom and a giant red button on the top. It served as an arena during the final fight with Chairman Drek.
- The 'RYNO4ever in Ratchet & Clank Future: Tools of Destruction was a weapon so dangerous it was made illegal for sales.
- The Ragnarok space station is capable of destroying anything off of the face of the Earth. (Mega Man Zero)
- The Moon Dagger from Terminal Velocity. This largue warship used a huge missile that cycled on the target a Fussion Transference Wave, whose effects are described as similar to what a sawed-off shotgun causes to a human.
- The trih xeem in the Marathon Trilogy. Name literally means, "early nova."
- The Void (Super Paper Mario) (this consumes worlds completely, leaving bleak, endless white plains in their place)
- Vegnagun in (Final Fantasy X-2) can be seen instigating the destruction of Spira in a "bad ending".
- Smoke's Destroy-The-Earth fatality and Grey-Goo ending (Mortal Kombat)
- Planet Busters of (Sid Meier's Alpha Centauri) destructive power ranges from destroying a city to a continent depending on their power source. When used, these weapons increased the chance of the planet's native life seeking to annihilate humanity. In the novelizations, four gravitational singularity–powered Planet Busters used by the Believer's trigger such an event.
- Cannon Seed (Galaxian 3)
- Sorcery Globe (Star Ocean: The Second Story) disrupts a planets 'Expel's' orbit and causes it to crash into Energy Nede.
- The USG Ishimura in Dead Space, a deep space mining vessel that extracts minerals from a planet by ripping away large chunks of the crust, and the other planet cracker vessels built after it. The Ishimura herself is said to have cracked 34 planets during her 62-year service. Also, the pre-Ishimura space stations used to "harvest" Titan. Then in Dead Space 3 it is found out that if the alien Necromorph"s markers convert all the planet's life into more Necromorph mass, the planet becomes a Brethren moon, a sentient planet size Necromorph that has the ability of interstellar travel and the telepathic powers of the markers who consumes all life one other planets.
- The Parasite Machine that sucks energy from the Earth's core in Urban Assault
- In Mass Effect, mass accelerators are the primary weapon design, ranging from small arms to multi-kilometer capital ship cannons. One weapon's projectile was powerful enough for a glancing blow to result in a large rift on a planet's surface, comparable to Valles Marineris. Also, various planet-grade WMDs are listed: nuclear weapons of varying yield, asteroids and space stations, and invasive species. Mass Effect: Bring down the sky DLC has a state sponsored terrorist group attempt to navigate an asteroid into a Human colony. Mass Effect 2: Arrival DLC offers the penultimum of kinetic weaponry: an asteroid equipped with a faster-than-light drive can match the power of a supernova; that's how much damage it takes to destroy a mass relay. Mass Effect 3 involves disarming an old Turian bomb that was placed on the Krogan home world in case of a rebellion
- The Giant of Bab-il in Final Fantasy IV is teleported to the Blue Planet/Earth for the express purpose of annihilating all life on the planet.
- In Final Fantasy V, Exdeath unleashes the power of the Void on the world; Neo-Exdeath (an amalgamation of Exdeath and all the creatures trapped in the Rift) clearly implies that the Void could destroy all life in the universe.
- In Final Fantasy IX, Kuja destroys everything within his homeplanet with a Ultima spell.
- Capital Vessels in R-Type have Wave-Cannons stated to be a hundred million times the power of the standard mass-production fighter's, and capable of destroying planets. The in-game description therefore indicates that each of the dozens or hundreds of fighters fielded in every fleet has a re-usable weapon with an output in the low Teratons.
- Izanami from the Blazblue series with the True Blazblue can turn most things on the planet to seither and render it a husk.
Anime and manga
Many characters in the series can destroy planets with the exception of the untrained human characters.

- Cell destroys King Kai's small planet towards the end of the Cell saga.
- The Original Super Saiyan destroyed the Saiyan's first home world when he couldn't control his power.
- The Spirit Bomb, a powerful technique taught to Goku by King Kai, must be controlled properly. If it isn't, the user can accidentally destroy the planet they are on.
- Dr. Wheelo attempts to use a planet killing technique to destroy the Earth and Goku.
- 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).
- One of the Outer Senshi, Sailor Saturn, can destroy an entire planet by just dropping her weapon (the Silence Glaive) with the intent to destroy, no attack calling necessary.
- Sailor Galaxia is also able to point at a planet and, if she possesses the will to, completely destroy it.
- The main protagonist, Sailor Moon, possesses the power to destroy an entire solar system, including its star.
In the first 3 Gall Force movies both sides the Solnoid and Paranoid Axis forces have had both their home worlds destroyed in a war of mutual assured destruction. They plan on using the last of their planet destroyers and include the new system destroyers in their final battle plans.
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 is made for taking out small galaxies.
"Space Battleship Yamato (Star Blazers)"
Throughout the series and movies, including Rebirth and the recent live action film, the Yamato (Argo) and similar battleships in the Earth Defense Force are armed with a Wave Motion Gun. This weapon of last resort is capable of obliterating entire fleets in one shot, as well as most moon and planetary sized objects. The downside of using this weapon is that it leaves the ship defenseless before and after firing due to the massive amount of energy needed to fire it (except in Rebirth, where the ship could fire six shots without recharging.) Also included would be the Desler (Desslok) cannon, built on the same principle (Tachyon Compression), and the main cannon in Zordar's dreadnaught, which was deployed at the end of season 2.
At the end of the series, it is established that the Coralians have the ability to engulf a planet and form their own version of a planetary crust, although they did not exercise it with the purpose of making a planet uninhabitable.
- Buster Machine III, aka the Black Hole Bomb in Gunbuster uses the mass of a gas giant planet (specifically, Jupiter) to create a black hole which ultimately destroys the center of the Milky Way galaxy.
- Galactus, a being from the Marvel Comics Universe, specifically the Fantastic Four books, consumes planets for their energy in order to sustain himself. He is often aided in this process by one of his heralds, the most famous among them being the Silver Surfer. His name is given to Galactus Syndrome. Also, there exists a great number of characters capable of planet busting.
- In DC Comics, the Warworld is a planet killer. As in Marvel, there is a great number of characters who can destroy planets.

- Big Venus (The Big O).
- Serpentera from Power Rangers.
- Erdammeru the Void-Hound (DC Comics)
- In Getter Robo Armageddon, the protagonists manage to create a massive Getter Beam Tomahawk powerful enough to slice through planets. Likewise, in some Getter Robo manga, an entire fleet of impossibly enormous Getter Emperors exist. These super-mecha are so large, they create their own gravity field that can actually shatter planets as they pass.
- In Vandread, A special variant of harvest ship can destroy planets that are not needed by Earth anymore.
- In the Eek! The Cat episode Eek vs. The Flying Saucers, aliens called Zoltarians threaten to blow up the earth using a death ray powered by Eek's 300-pound girlfriend, Annabelle, and want to do so because Earth "obstructs our view of Uranus."

- The Beast Planet in Shadow Raiders.
- The Desiccator in Dark Reign.
- The Ideon Sword (capable of slicing a planet in half) and the Ideon Gun (capable of cutting large swaths of destruction encompassing thousands of ships and celestial bodies) from Space Runaway Ideon. In addition, when ultimately destroyed, the resulting force caused by the detonation of its power source could potentially destroy the universe.
- The Planet and System Killers in Gall Force.
- The Dark Heart in Justice League Unlimited.
- In the Macross Saga segment of Robotech, when the entire Zentradi main fleet was brought together it could destroy the entire surface of a planet through large bombardments of its energy weapons. In Robotech continuity, the Neutron-S missile is thought to be an extremely powerful bomb, but it turns out to be a planet killer since it creates artificial singularities and hence turns any target into a black hole.
- Rave Master describes two powers capable of wiping out all life: the power of Etherion contained in the body of Elie and the being called Endless.
- The largely undescribed cascade missile in Sluggy Freelance (in the science fiction parody in chapter 24, "GOFOTRON Champion of the Cosmos").

In his discussion of the tradition of apocalyptic cinema Mitchell exemplifies what the film Doomsday Machine or Escape from Planet Earth characterizes as a "planet-buster" as belonging to the class of "Doomsday device". Secondary literature can also use terms like "planet-cracker" or "planet-busting superweapon".
As astronomer Phil Plait has pointed out, the amount of energy necessary to shatter an Earth-sized planet is extremely large: "about 2 x 1032 Joules.... about as much energy as the sun puts out in a week."
