List of fictional doomsday devices explained

Doomsday devices, when used in fiction, are capable of destroying anything from a civilization to an entire universe, and may be used for the purpose of mutually assured destruction, or as weapons in their own right. 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 franchise.

Overview

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 Buster 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.

Alpha Omega Bomb - an ICBM worshiped by the underground dwellers. The missile contains a thermonuclear bomb with a cobalt casing. When launched it would result in an explosion hot enough to ignite the atmosphere, thus destroying the surface of the Earth.

Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb

The end of the film (when Russia's Doomsday Device is released) shows Dr. Strangelove exclaiming, "Mein Führer, I can walk!" (to the American President) before cutting to footage of nuclear explosions, with Vera Lynn and her audience singing "We'll Meet Again". This footage comes from nuclear tests such as shot "Baker" of Operation Crossroads at Bikini Atoll, the Trinity test, a test from Operation Sandstone and the hydrogen bomb tests from Operation Redwing and Operation Ivy. In some shots, old warships (such as the German heavy cruiser Prinz Eugen), which were used as targets, are plainly visible. In others, the smoke trails of rockets used to create a calibration backdrop can be seen. "The film is often considered one of the best comedies ever made, as well as one of the greatest films of all time." - Wikipedia: Dr. Strangelove

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.
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, fifth 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.
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 "The Big Bang" the TARDIS nearly destroys the Universe when it explodes by unexplained means in "The Pandorica Opens".
The Hand of Omega can be used to destroy planets by manipulating stars, as demonstrated on the Dalek homeworld Skaro.
The Osterhagen Key detonates 25 nuclear weapons in strategic points under the Earth's crust, causing it to rip apart. Only be used if "Humanity were suffering unbearably, with no hope or help ever coming..." in "The Stolen Earth" and "Journey's End".
The Tenth Planet, set in 1986, features the Z-Bomb, a weapon that could destroy the Earth, at a South 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 "Remembrance of the Daleks" The Doctor explains that the Dalek mothership "has weapons that could crack this planet like an egg".

In the TV series , 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 science fiction feature film The Core, Project DESTINI was designed as a tactical weapon, but had the unforeseen effect of ceasing the rotation of the Earth's magnetic core, causing catastrophe, and threatening to end all life on Earth, unless the rotation could be restarted.
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 is that the knowledge of wormholes contained in the head of John Crichton can be used to create a planet-killing weapon; in 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.

In Spaced Invaders the D.O.D. (Doughnut Of Destruction) is a ring-shaped device which the aliens claim would destroy Earth but leave them unharmed as they would be in the center of the blast. Upon activation the device fails to detonate, but instead falls apart, having been improperly assembled.
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 . 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 in 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. In the Monsterverse film Godzilla: King of the Monsters, the creature is capable of creating massive superstorms which, had the creature not been killed by Godzilla, would have rendered Earth effectively uninhabitable by anyone save itself, as it is stated the creature intended to reshape to the planet to suit its own needs. 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 science fiction series season 2 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", and subsequently launches an Eagle, what the villain of the episode Mentor reveals as "A Robot Device, designed to destroy Psychon". One can assume that the Eagle was heavily equipped with nuclear charges, sufficient enough to at least destroy life on the planet.
In , the Red Lantern Corps ship, dubbed Shard, carried giant monolith-shaped devices called "Planet Killers" that were bombs capable of destroying entire planets.
The Dark Heart from Justice League Unlimited.

Literature

The Deplorable Word, as used in The Magician's Nephew, by author C. S. Lewis, is a magical curse which ends all life in the fictional world of Charn except that of the one who speaks it (see Omnicide).
Obliterators used by Honored Matres in Frank Herbert's (1985) and later sequels by other authors are capable of combusting the entire atmosphere of a planet, and ultimately its full surface.
Stone burners, a type of nuclear weapon which could potentially destroy a planet by burning into and destroying a planet's core in the Dune universe.
Vogon Constructor Fleets in The Hitchhiker's Guide to the Galaxy. 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, book, and the 1981 TV series 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)^[3]
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 Xeelee have a handgun-sized weapon capable of destroying stars and neutron stars. Also, during their final war with humanity from 700,000 AD, the Xeelee built giant Dyson shells around every star in the Milky Way, which 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:
1. "super-atomic bombs"
2. rendering a planet "loose" (inertialess) and directing it into a star
3. a "nutcracker", maneuvering two loose planets to crush a third
4. a "negasphere", an antimatter planet^[4]
5. "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
6. 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.
Device Ultimate in The Xenocide Mission
In Kevin J. Anderson's Saga of 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 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.
In Greg Bear's The Forge of God, alien aggressors inject two high-mass weapons made of neutronium and antineutronium into the Earth which orbit the Earth's core until they meet and annihilate, destroying the planet.
L. Ron Hubbard's Battlefield Earth (1982) planet-buster tactical nuclear weapons^[5] are teleported to a distant planet, where they are contained in a protective force-field that directs the blast into the mined-out and somewhat hollow planet. It first causes apocalyptic volcanic activity as half of the bombs' force breaks the crust and reaches the core, and the rest creates such temperature and pressure that it undergoes nuclear fusion and becomes a star. Battlefield Earth also features a device known as the "Psychlo ultimate bomb", which, when activated, causes all matter it touches to break down into hydrogen atoms (technically fission, although there is no mention of release or absorption of energy). The device featured at its core a sphere of extremely dense metal with an atomic number considerably larger than any listed on any periodic table of elements. This device was used on a moon, which was consumed faster than ships based on that Moon could launch. The resulting cloud of hydrogen later compressed under its own gravity, analogous to a gas giant planet. It is implied that it developed electron degeneracy, as it was described as having an electric field of "uncountable quintillions of megavolts" and would vaporize anything that approached it with an electric arc.
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)(Andromeda TV Series)
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 star's 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 on 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.

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.
Quark bombs in the novel Lord from the Planet Earth by Sergey Lukyanenko. A group of radical cultists from another planet wanted to destroy Earth with a quark bomb, but are foiled by the protagonists.
The Q-bomb, a prototype doomsday device that could destroy the world if triggered in The Mouse That Roared, a 1955 novel by Irish American writer Leonard Wibberley.
In Chris Walley's Lamb Among the Stars novels, a polyvalent fusion bomb is capable of rendering a planet inhospitable due to radiation if detonated in a solar system. Project Daybreak was intended to inject one into the core of a star, with an estimated blast radius of several dozen light-years.
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.
In the German science fiction series Perry Rhodan, the humanoid Arkoniden (English: Arconides) had the Arkon Bomb, which could destroy an Earth-sized planet within hours, or the Lemurians, the ancestors of the Arconides and the Terrans, had the Armageddon Bomb which was similar to the Arkon Bomb. The tyrannical rulers of the Andromeda Galaxy had planet killers, which could devour whole planets and were referred to as "Mobies" by the fictional characters within the series. In this series, weapons with the power to eliminate whole galaxies were mentioned as well.
In A Hole in Space by Larry Niven, Monk ships carry a stern-facing device called the hachiroph shisp which causes stars to go supernova. The Monks use these devices to propel their ships from star to star, unless the star they are visiting has a civilization that can build a launching laser for them to use instead.
Hypernet gates in The Lost Fleet explode when disrupted, with a yield ranging from insignificant to supernova-level depending on the order in which the gate's many "tethers" are destroyed. The alien Enigmas provided the technology to humans during a large war, hoping that humanity would destroy itself when the warring factions (the Alliance and the Syndicate) discovered the gate-collapse technique and began using it on each other.
In The Shiva Option, the Bug "home hive" systems are neutralized by carpet bombing their inhabited planets with antimatter munitions.
In The Mortal Engines Quartet by author Philip Reeve, set in a post-apocalyptic world, the ODIN device is an ancient orbital energy weapon capable of destroying whole cities in a single blast. Stalker Fang, a main character in the series, plans to use ODIN to target volcanoes to plunge the Earth into a volcanic winter to extinguish humanity, which she sees as responsible for all of Earth's problems.
In Rainbow Six a group of bio-terrorists attempt to release a virus which will kill almost all human life on Earth.

The E.C.Tubb story 'Little Girl Lost' (also, a filmed adaptation was done for USA TV Series NIGHT GALLERY) presents a scenario where a researcher, working on atomic weapons (in the TV adaptation, he is working for the US, in the original, for the British government) suffers a nervous breakdown when his daughter is killed in a car accident. In order to keep him working at his project, a psychologist is brought in to keep him in a delusional state, thinking that she is still alive ... it seems that he is completely fooled by this ruse until the end, where it is discovered that his weapon can (and does) destroy the planet, or at least that is implied ...

▪ Stephan Ames Berry Kronarian book series has two versions of planet busters one produced by the old imperium burrows into a planets cores and explodes destroying the planet from the inside out. The other was produced by the Trel called a worm maker creates a wormhole to consume a planet or in some cases whole solar systems. this one was copied by the antagonist AI's and was used against them destroying their fleet.

The System Killer as well as the Von Neumann Construct random menaces from the Sword of the Stars series.^[6]
The Annihilaser from Planetary Annihilation is used by building 5 massive Catalysts on the north pole of a metal planet, allowing the player to fire a weapon from it. After a short charge, the planet will rotate to its target and fire an extremely powerful beam of energy that goes straight though a planet, expanding and destroying it. The Annihilaser can destroy any rocky planet regardless of size, and can even destroy small planets that are being fired at another planet. It cannot destroy gas giants or stars.
Ragnarok, again from Planetary Annihilation, is a doomsday structure that, once built, deploys and drills a hole to the mantle of a planet for one minute before dropping a device into the core, exploding it in a fashion similar to the Annihilaser.
EA and Maxis' 2008 life simulation Spore features some examples in the game's "Space Stage", accessible once a civilisation evolves enough to develop space travel.
- The Planet Buster is described as a superweapon "feared by all", capable of destroying an entire planet with a single blast by causing its mantle to expand and turn the planet into a ball of lava. This weapon breaks the Galactic Code, causing a heavy relationship penalty to any empire within 10 parsecs of the planet destroyed. However, the Grox, a malevolent empire, will instead be impressed if they witness its usage on a planet that isn't theirs.
- Another planet-killer in Spore are the terraforming tools. While unable to completely shatter a planet, they can destroy the ecosystem, freeze or melt the planet, or make the atmosphere too thin or thick for life to survive, regardless of whether there's life on the planet or not. Planets with colonies may lose cities depending on the T-level the planet ends up at after being terraformed, with planets at T-0 only being able to support one City Hall. The Grox species are the only exception, being able to prosper at T-0 and losing their cities at any higher level.
- Using the Fanatical Frenzy ability (only available to the Zealot class) hastily converts an entire planet to your religion and replaces its residents with yours. It instantly conquers it and breaks the Galactic Code, though it's not explained in-game whether it actually kills the original population.
- The Gravitation Wave (only available to the Scientist class) is a bomb of very tightly packed gravity, instantly levelling all structures and killing the planet's sapient inhabitants. It does not outright destroy a planet, but it breaks Galactic Code and destroys its population.
The Hammer of Dawn in the Gears of War series could wipe out an entire civilization with ease.

Tiberium in the Command & Conquer franchise slowly eats away at the Earth.
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).

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 – 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 "Weak nuclear force decoupler" from Perfect Dark (Nintendo 64)
The Space Colony ARK's Eclipse Cannon from Sonic Adventure 2 and Shadow the Hedgehog
The Alphacore (Omega Boost)

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 De-Planetizer's purpose was to break planets apart so that Chairman Drek could harvest choice fragments to assemble into his own new planet.
The Ragnarok space station is capable of destroying anything off of the face of the Earth. (Mega Man Zero)

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.
In Dead Space 3 it is found out that if the alien Necromorph 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 on 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 an unusual form of kinetic weaponry: an asteroid equipped with a propulsion drive with enough power to destroy mass relay. Mass Effect 3 involves disarming an old Turian bomb that was placed on the Krogan home world in case of a rebellion.

In Final Fantasy IX, Kuja destroys everything within his home planet with a Ultima spell.
In the original release of Final Fantasy XIV, the main antagonist Nael van Darnus pulls the lesser moon Dalamud from orbit in an attempt to destroy the beast tribes and the primals they worship. In reality, Dalamud is an artificial satellite used as a prison for the elder primal Bahamut, who destroys the world in a rage upon his release. The relaunched version and tts expansions expand upon this; Dalamud's fall and Bahamut's rampage were amplified by a phenomenon known as the Rejoining, in which the global story arc's antagonists, the Ascians, "rejoin" an alternate dimension split from the world, causing mass destruction and strengthening their god, Zodiark.
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.

GURPS Spaceships presents the Relativistic kill vehicle Azrael, described as a large AI-controlled missile that impacts its target with a force of 42 million megatons -enough to trigger an extinction event-.
In Kirby Super Star Ultra, a warrior known as Galacta Knight makes his debut. He is referred to as the greatest warrior in the galaxy and a warrior who was sealed away because his power was too great, as mentioned by the Galactic Nova. He later appears in , in which he is summoned by Star Dream, who says: He may end up destroying a nearby planet or two, but such is life.'. This indicates that Galacta Knight could quite easily destroy up to two planetary bodies at a time.
Void Termina (Kirby Star Allies) is mentioned to be the Destroyer of Worlds on his splash screen. This can be shown to be a valid description when his death causes a supernova.
In the Traveller roleplaying game there is a highly advanced weapon called a planet buster. It is believed to have been used by the ancients during the war that resulted in their extinction. It is very difficult if not impossible to gain one of these in a normal game.
The Ruin in Starbound is an ancient and giant biological being capable of destroying planets,it loathes all life and tries to kill it all and it was controlled by Arsa Nox and is the final boss of the game
In Outer Wilds, the alien race known as the Nomai constructed a space station capable of prompting its parent star to go supernova, destroying all planets within the blast. The Nomai would use the energy released to power the Ash Twin Project, sending a user's memories back in time 22 minutes. The Ash Twin Project was also linked to a probe cannon looking for a distant body known as the Eye. Sending the memories of the users and the data from the probe back in time allowed the probe to be fired an indefinite number of times, and for the loop to stop in the case of an emergency. Once the Ash Twin Project succeeded, it could tell the sun station to stop firing allowing the Nomai to find a way to travel to the Eye. However, the Sun Station did not output enough power to cause a supernova, and the Ash Twin Project would have to wait until the end of the Sun's natural life cycle to begin a time loop. At the end of Outer Wilds, the player does not find a way to stop the supernova, and must travel to the Eye, having deactivated the Ash Twin Project, using an ancient crashed ship whom the Nomai originated from. After a while, the Universe dies from heat death as all stars reach their deaths and go supernova, destroying all solar systems in the Universe, except for the Eye situated far enough from the blast of the Sun.
Also in Outer Wilds, interrupting a warp when there's still a duplicate of an object from the future will cause spacetime to break, presumably causing everything to cease existence.
In Fortnite Battle Royale, during the Chapter 2 Season 2 live event, the character of Midas builds a Doomsday Device in order to push back the storm from the loop, attempting to allow the loopers (players) to escape. The device fails, and the storm is turned into a gigantic tsunami.
Also in Fortnite Battle Royale, during the Chapter 3 Season 2 live event, the Imagined Order create a Doomsday Device in order to put an end to The Seven and restart the loop. They are stopped by The Paradigm controlling the rebuilt Mecha Team Leader while players control the guns of the mech.

Space Battleship Yamato (Star Blazers)

See also: Space Battleship Yamato. 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.

Secondary literature

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"^[7] as belonging to the class of "Doomsday device".^[8] Secondary literature can also use terms like "planet-cracker"^[9] or "planet-busting superweapon".^[10]

Science journalism

In the field of science journalism, a 1962 article examined various means "to put an end to the world", concentrating on "Doomsday Bombs".^[11]

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."^[12]
