The CoolShip needs an equally cool weapon. If it's a sufficiently humongous CoolShip, it will be equipped with a [[FrickinLaserBeams Laser Beam]] on steroids: the Wave Motion Gun -- an enormous RayGun that fires a massive energy beam capable of blowing away an enemy ship (in the "blow a battleship in half" sense), sometimes an entire fleet, with one shot, and maybe even [[EarthShatteringKaboom blowing up an entire planet]]. Sometimes, it doesn't necessarily have to hit. If you're too close, the sheer energy bleeding off from the beam can be deadly. And don't think about trying to ward it off with DeflectorShields.

Frequently, the Wave Motion Gun is made of LostTechnology, or is [[NoPlansNoPrototypeNoBackup an experimental prototype]], but sometimes they're a dime a dozen. It also explains how a small fleet can win consistently against enemies that grossly outnumber them: the defense units just have to hold their ground until the Gun(s) is ready to fire. Invariably, just before firing, TheCaptain has to [[CallingYourAttacks order the attack]].

This sort of weapon could also qualify as a KillSat, or a {{BFG}} if it is held or installed in a HumongousMecha. If it's built into a famous real-world location, then it's a WeaponizedLandmark. If the bad guys have one, it's a DeathRay. Wave Motion Guns usually require a significant charging period before firing and re-charging/cooldown afterwards (occasionally depicted by SuckingInLines. The WaveMotionTuningFork is a popular subtrope used for visual effect.) Can lead to [[IncrediblyLamePun Wave Motion Fun]].

WaveMotionSword is the [[SwordBeam sword]] counterpart to this trope.

!!Examples:

[[foldercontrol]]

[[folder: {{Anime}} and {{Manga}} ]]

* The [[TropeNamer eponymous main weapon]] of the ''UchuuSenkanYamato''. Notably, the original Wave Motion Gun itself wasn't just a heroes-only weapon. By season 2 most ships in the Earth Defence Force carried one.
** Also, once exposed to the Wave Motion Gun, everyone else tried to copy or modify one. Desslok/Dessler had his Desslok Cannon, said to be weaker than the Wave Motion Gun, but not so much that you'd really notice, and the Comet Empire had their weaker (only one ship at a time), but longer ranged 'Magna-Flame Cannon'.
** ''Blue Noah'' the expy/ripoff of Yamato by the same producer (The Nish) has the Anti-Proton Gun.
* The Macross Cannon, AKA Superdimensional Converging Beam Weapon, as well as the Grand Cannon, in ''SuperDimensionFortressMacross'' and its sequels. Originally found on most Zentradi ships of the line, by the time of ''MacrossFrontier'' the concept is increasingly common in the U.N. Spacy fleet, finding itself as the Heavy Quantum Convergence Cannon of the smaller carrier Macross Quarter.
** ''Frontier'' really takes a cake here. They managed to pack a fully functional (if smallish) Macross Cannon into a ''[[TransformingMecha fighter]]''! It doesn't have [[ThereIsNoKillLikeOverkill as much oomph]] as does battleship version, but stil has enough power to punch out the DeflectorShields of a capital ship.
** Notably, the original Macross Cannon provided the impetus of the plot: the [[NeglectfulPrecursors Supervision Army]] gunship that later became the Macross had been rigged to fire upon Zentradi reconnaissance ships, which it did, prompting the arrival of a full combat fleet. Also, activation of the ship's [[TransportersAndTeleporters Fold Engines]] left the Cannon bereft of power conduits for a while, prompting the [[TransformingMecha iconic transformation]] (which allowed the Cannon to reconnect with its power source due to the new configuration.)
** Also, while the original Cannon was an integral part of the Macross' design, posterior models of similar (and superior) classes modified it into a detachable gunpod.
** The Zentradi Mobile Fortresses (Fulbtzs Berrentzs class) were each equipped with a Wave Motion Gun so powerful that any direct fleet engagement essentially boiled down to the question "who will be the first to fire?" This is vividly demonstrated in the original movie where Bodolza is so adamant about opening up on Lapramiz' MF that he willingly sacrifices thousands of his own screening force ships which just happen to be in the line of fire.
* Synchro Cannons in ''RobotechTheShadowChronicles''.
* The Nadesico, from ''MartianSuccessorNadesico'', had the Gravity Cannon. When that got old and stopped working against the enemy, they upgraded to the Phase Transition Cannon.
* ''MobileSuitGundam'' and its sequels, spinoffs, and {{Alternate Universe}}s have a number of these, starting with the Solar Ray, an entire space colony converted into a laser cannon ([[ThatsNoMoon That's no space station...]])
** The ''Gundam Wing'' anime has a veritable collection of these:
*** In the early episodes, the role was filled by the Noventa Cannon, which barely had a chance to fire once before it was dismantled piecemeal by no more than two mobile suits manned by secondary character pilots.
*** Next came the cannon mounted to the Fortress Barge space battle station. In keeping with wave cannon tradition, it required a lengthly charging time and room of technicians to fire properly.
*** Finally, the weapon mounted to Battleship Libra was the series' crowning achievement in high-velocity destruction. Along with wiping out any number of generic mobile suits, it destroyed not one, but two of the titular Gundams. Also, it's lengthly recharge time was [[JustifiedTrope justified]] due to the fact that the engineers who designed it built a flaw into the design so that it could not be fired in rapid succession.
*** Wing Gundam's signature Buster Rifle happened to be a ''[[{{BFG}} handheld]]'' one of these, and its successor Wing Gundam Zero wielded a ''Twin'' Buster Rifle that not only packed twice the firepower, but could be [[BifurcatedWeapon split into]] [[GunsAkimbo a pair of Buster Rifles]]! The Twin Buster Rifle is so powerful, [[spoiler: that the recoil from firing it 3 times in a row is one of the primary causes of the destruction of the Wing Zero Custom]]
***In ''Endless Waltz'', there is the Tallgeese III's Mega Cannon, which Zechs uses to destroy the Mariemaia Army's base at asteroid MO-3.
***Though not as devastating or as iconic as the Wing or Wing Zero's Buster Rifle, the Vayeate mobile suit carried around a large rifle very similar to its counterpart on the Gundams. Considering the Vayeate's purpose was to focus entirely on offensive capability and that it was designed by the Gundam Scientists, saying this laser was big may be something of an understatement.
** ''Gundam SEED'' and ''Gundam SEED Destiny'' have a few of 'em:
*** ''Gundam SEED'' spacecraft of the Archangel (Earth Alliance vessels; specifically, the Archangel and the Dominion) and Izumo (Orb vessels; the Kusanagi) class have a weapon known as the Lohengrin, which is quite close to being a Wave Motion Gun. It shoots a beam of ANTIMATTER at the target, although it's somewhat based in fact: It is a positron beam cannon, and positrons are a form of antimatter that have been proven to exist (they're electrons, but with a positive charge instead of the requisite negative charge). They have to be charged before use, which involves SuckingInLines.
**** Positron guns in ''SEED'' and ''Destiny'' are clearly based on aforementioned ''Blue Noah'' version, up to the placement of the gun and charging animations. A long tradition, there!
*** The GENESIS (from ''Gundam SEED'') is a Wave Motion Gun powered by freakin' NUCLEAR EXPLOSIONS! (Technically it fires a laser made of gamma radiation instead of light)
*** ''Gundam SEED Destiny'' has the Archangel and Kusanagi, which still have their Lohengrins. There are more Izumo-class Orb vessels, as well, meaning there are even more ships with the weapons, as well as artillery versions used by ground forces. ZAFT even gets in on the action with the Minerva, which has the Tannhauser, a positron cannon (essentially a positron beam cannon without the word "beam" in its name).
*** Remember the GENESIS from ''Gundam SEED''? Well, ''Gundam SEED Destiny'' has the Neo GENESIS. It's a smaller, faster-charging version of the original GENESIS, which was destroyed at the end of ''Gundam SEED''. ''Destiny'' also has the Requiem, which is a giant beam cannon fired from the far side of the moon (its beam can be redirected with magnetic fields, allowing it to be aimed at virtually anything).
**** And don't forget GENESIS Alpha in GundamSEEDAstray.
** The Satellite Cannons of ''Gundam X'', which had the power required to fire it beamed to it from a base on the moon.
** ''{{Gundam 00}}'' has Virtue's and Seravee's GN Bazookas, as well as Memento Mori in the second season.
*** Don't forget the Gadessa's GN Mega Launcher, or the GN Particle Cannon on BigBad's mothership with the power to take out an entire fleet.
** It's actually kinda of a custom in ''Gundam'' now that every series must a huge Wave Motion Gun, sometime even two in one series. It usually involved in the final battle or close to the end. It is usually destroyed by the heros blowing up its [[ForMassiveDamage weak point]] and causing the whole thing to go kaboom.
**The Gryps 2 Colony Laser apparently figured prominently in ''ZetaGundam''.
**GGundam goes BeyondTheImpossible with CrazyAwesome with Neo-America's secret weapon- the Statue Of Liberty Cannon! It shoots from the torch.
* The Iron Ri Maajon (and a number of other Ri Maajon patterns) from ''{{Simoun}}''.
** They aren't ''guns'', they're Wave Motion ''Prayers''.
* The Positron Rifle from ''NeonGenesisEvangelion''. The rifle can manage just two shots in the available time and needs to be ''slowly charged with all the electrical power of Japan''.
** The angel said Positron Rifle is employed against (Ramiel) produces a beam that goes through several buildings. Then it applies [[TimTaylorTechnology more power]] and fires right through a custom heat shield many meters thick. Next comes a series of blasts that seriously disfigure the surrounding countryside, vaporizing elements of Tokyo 3's point defense system. Finally (when hit by a beam from the Positron Rifle mentioned above), it gets ''[[TurnsRed really pissed off]]'' and charges a blast that ''melts away'' a fairly large mountain.
*** They also had a Positron Cannon, a combat version of the Rifle(the rifle was a prototype and wasn't supposed to be used at all). Too bad it didn't really help Asuka when facing off against the 15th.
* From ''MagicalGirlLyricalNanoha'', the title character has three attacks that are basically a magical Wave Motion Gun, the first being "Divine Buster," the second being "Excellion Buster," and the third being the ''even more'' powerful "Starlight Breaker." The CoolStarship, the Asura, also has the "Arc-en-ciel".
** Several of Nanoha's other characters have Wave Motion Guns of their own; Fate and Hayate in particular have their respective attacks "Plasma Zamber Breaker" and "Ragnarök Breaker", and the original Reinforce had a virtual arsenal of these attacks, some of them copied from the heroines.
*** Hayate probably still has most of them.
* Arika's "Bolt From The Blue" in ''{{Mai-Otome}}''. Unfortunately, her equal and opposite number Nina has a similarly-powerful attack as well [[spoiler:in both her robes]]. Natsuki also has her Howling Silverwolf attack, debuting near the end of the series in a massive BeamOWar with Nagi's siege cannon.
** Similarly, in ''{{Mai-HiME}}'', Mai's [=CHILD=] Kagutsuchi can take out an entire aerial fleet.
* The super weapon in ''BlackHeaven'' falls under this trope as well as being rather hard to activate.
* The rifles carried by the gigantic Nobuseri leaders almost qualify, but more properly, the main guns of the Imperial Capital ''[[SamuraiSeven Samurai 7]]''.
* One of the most powerful ones is the Ideon Gun from ''SpaceRunawayIdeon'', which can devastate a good portion of a star system. It's particularly fun to use in the SuperRobotWars series, as it can oftentimes wipe out the entire enemy force (and maybe some friendlies) in a single shot if you line it up right.
* Both the OVA and TV incarnations of Ifurita from ''[[ElHazardTheMagnificentWorld El Hazard]]'' wield a wave motion gun in the form of her "Power Key Staff." How she wields it is probably the crucial difference between the two worlds: OVA-Ifurita is a tragic figure, struggling to balance her nascent emotions with her nature as a living weapon of mass destruction; TV-Ifurita is a [[{{Cloudcuckoolander}} massive ditz]] with a ''really big gun''.
* The manga series ''{{Blame}}''! features the ''Gravitational Beam Emitter'', a wave motion '''''pistol'''''. Its power is so great that if it were to be used in a regular atmospheric environment (like, you know, ''ours''...), it would have irreversible environmental side effects. [[InformedAbility Or so]] [[WordOfGod we've been told...]]
* In the ''{{Digimon}}'' franchise, a few machine-based {{Mons}} have these, most notably Imperialdramon (his type isn't Machine if you wanna get technical, but his design is based on TransformingMecha.) He's got ''three'', ranging from "standard finishing attack" to "frag the whole area" to "SpiritBomb as strong as a small nuke."
* Odd as it might seem, Excalibur from ''FateStayNight'' and ''FateZero'' is essentially a Wave Motion ''Sword''. When [[PowerGlows it is charged]], it can fire off [[SwordBeam waves of destructive light]]. Using it one-handed reduces it to mere concrete-rending level; using with both hands can raze cities.
** Ea, the Sword of Rupture, was specifically designed to resemble [[EverythingsBetterWithSpinning a subterranean tunnel drill]], and [[PowerGlows once charged up]]--via, naturally, spinning--it can rip apart spacetime. So far, it is the only weapon in {{Nasuverse}} ever classified "Anti-''World''."
* Bizarrely enough, ''OnePiece''. How often do you see a pirate sloop armed with one of these things?
* ''TheBigO'' has the [[ForgottenSuperweapon Final Stage]] attack, which, [[spoiler:in something of a twist, ''misses''.]]
** [[spoiler:It still quite neatly eliminated almost half of the [[BigBad Big Bad]]'s [[HumongousMecha Megadeus]].]]
*** [[spoiler:Not that the missing half matters, as Big Fau is still functioning after the blast.]]
* Hadron cannons in ''CodeGeass'', which come in both mech-mounted and battleship varieties (the latter are the really powerful ones). Then there's the Guren's Radiant Wave Surger...
* Guchuko from ''{{Potemayo}}'' has two "horns" on the sides of her head that function like this.
*In ''{{Zoids}}'', a few Zoid types are equipped with Charged Particle Cannons, usually piloted by [[TheDragon Dragons]] or the [[BigBad Big Bad]]. Of particular note is the Berserk Fury, which has ''three'' charged particle cannons.
* ''NausicaaOfTheValleyOfTheWind'', anyone? The God Warrior's primary weapon is essentially a WMG. [[spoiler: Which is of the same design, origin, and firepower as the Eye of the Crypt of Shuwa. The God Warrior and the Crypt even fire their respective beams at one another during the manga's climax.]]
** While we're on Miyazaki, we forgot ''{{Castle In The Sky}}''! Sodom and Gomorrah were but two places destroyed by it, according to Muska.
* In the original ''GetterRobo'', the Eagle Unit (one of the three machines that forms the titular CombiningMecha) was a small jet that could fire puny laser beams. By ''Shin Getter Robo'' it had [[BiggerIsBetter upgraded]] [[BeyondTheImpossible itself]] to a ''beyond planet sized'' star-ship, and its laser appropriately became a fleet/planet busting Wave Motion Gun with an energy output high enough to potentially ''cause a Big Bang.''
** And in ''Will of Evolution'' [[spoiler: it actually happens. In fact, it's implied that this is how the universe was created. By a HumongousMecha-slash-CoolShip shooting beams of [[EvolutionaryLevels evolutionary energy]] into space]].
* [[{{Trigun}} Vash the Stampede]]'s Angel Arm is a proper, honest-to-goodness wave motion gun. If it gets shot at medium power, it annihilates entire cities. If it's shot at full blast, it ''carves gigantic craters in other planets''. The best part is that it basically consists of a tiny cylinder of AppliedPhlebotinum in his revolver. Talk about miniaturization...
*In the ''{{Naruto}}'' manga series, [[spoiler: Pain, the BigBad leader of the Akatsuki, uses a gravity-based version of this to ''flatten Konoha'']].
** [[spoiler: Flatten is an understatement.]]
** [[spoiler: Or the Technique he wanted to make with the Bijuu, capable of destroying entire COUNTRIES in an instant.]]
*** Maybe. Given that [[spoiler:the things are really the chakra of some sort of EldritchAbomination]], who knows what that "weapon" really was.
** Naruto and KillerBee have their own version. At full power Bee's destroys part of a mountain range. Naruto's is less spectacular, with only half power, but still manages to leave a trail of destruction several miles long.
* Possibly a lampshade on this in ''ExcelSaga'', where Excel calls the weapon on the Puchuu starship a Wave Motion Gun.
* Parodied in ''SoraWoKakeruShoujo''. When Leopard asks Akiha to fire his antimatter cannon -- and he's a living space colony, so this is a huge cannon -- he prepares for it with bravado. It's a dud. Then played straight when the right components are obtained. [[DoesThisRemindYouOfAnything The show being what it is, though...]]
*''TengenToppaGurrenLagann'' 's [[spoiler:Big Bang Storm is a borderline version; How many times do you see someone being attacked with the [[NoKillLikeOverkill Everlasting Hellfire of The Universe's Creation]]?]]
** What's more important about this one is the fact that [[spoiler:the main characters not only block it, but through sheer awesome ''absorb'' it and turn its power against its wielder.]]
* In ''ElHazardTheMagnificentWorld'' Ifurita's full power gun blast is basically a "nuclear bomb ray." She destroys an entire city with in in the anime, and a mountain in the manga. It takes some time to recharge, but not much.
* Evangeline from ''MahouSenseiNegima'' uses one to blow up the Demon God in the Kyoto arc.
** [[spoiler: One of Asuna's [[FlashBack Flash Backs]] reveals during magical war, among (slightly smaller than the above mentioned demon) god solders, ancient war dragons, and [[MagicKnight Magic Knights]], [[SpaceWhale battle whale ships]] that wielded one of these called the divine/spirit cannon. Presumably the strongest artillery weapon in the [[MagicalLand Magic World]], Asuna's [[AntiMagic Magic Cancel]] completely eliminated it]].
* ''Detonator Orgun'' has a solar-powered, chest-mounted WMG.
* ''{{Guyver}}'' has the Giga-Smasher, a plasma cannon whose range, beam width, and power appear approximately equivalent to a Macross Cannon.
** That's a [[spoiler:one shot weapon only, however. It can only be used one time by one of the Guyver's equipping the Gigantic upgrade; One shot with the Giga-Smasher uses up the upgrade's energy reserves and it automatically disattaches from the user, leaving them with just their normal Megasmasher and an assload of fatigue.]]
* ''TheFiveStarStories'' has the Buster Launchers, enormous cannons the bigger of which (starting from the 2 meter caliber) are fully capable of [[EarthShatteringKaboom obliterating planets]]. The common ''Prowler'' [[OldSchoolDogfighting fighter]] usually mount at least two of these, and as such is considered [[{{Understatement}} somewhat]] [[ThereIsNoKillLikeOverkill overpowered]], and was replaced by the [[HumongousMecha Mortar Headds]] planetside. Later, though, a couple of [=MHs=] were armed with busters, making them the most heavily armed mechas in the universe.
* ''MazingerZ's'' [[ChestBlaster Breast Fire]] was always close to this, but ''{{Mazinkaiser}}'s'' Fire Blaster goes all the way when it's fired over the heads of several Mechanical Beasts... and ''still'' melts them.
* The flagship of the Iron Tribe's fleet is equipped with one of these in ''HeroicAge''. It can destroy and ignite entire planets, causing massive shockwave damage to nearby units. The Az-Azoth fleet commanded by Nilval Nephew also has specialized "core" units that apparently serve no other purpose than to be enormous space-based cannons. Bellcross's rarely used mouth-beam attack also qualifies, as does Artemia's more powerful beam attacks. Finally, [[spoiler: the Argonaut has the capability to shift into an enormous gun form, firing a WaveMotionGun aptly named the "Star Blaster".]]
* Something that has remained fairly constant throughout the various incarnations of AstroBoy is Astro's arsenal. One of his staple weapons, aside from the small laser guns in his fingertips (and the infamous machine gun barrels in his butt), is turning his arms into laser cannons.
* In ''{{Bleach}}'' [[spoiler:Coyote Starrk]] has pistols that fires CERO, in his released form. Think of Gravitational Beam Emitter. Did I mention that he has ''two'' of them?
* EurekaSeven: [[spoiler: The ultimate attack of the spec-[=III=] Nirvash [=typeZero=].]]

[[folder: {{Film}} ]]

* The best-known example of all is the Death Star's planet-destroying Superlaser in ''Star Wars''.
** Followed by the Expanded Universe Eclipse-class Super Star Destroyer's
* The "Death Blossom" that was installed in ''TheLastStarfighter'', although that's more of a MacrossMissileMassacre combined with a bit of BeamSpam rather than a Wave Motion Gun, but has the same energy-draining drawback.
* The Zeus Cannon from ''[=~Final Fantasy: The Spirits Within~=]''.
* {{Gamera}}'s Mana Cannon and any variant of {{Godzilla}}'s Breath Weapon, be it Red, Golden or [[ThisIsADrill Spiraling Red]] all count as such. When things are hit with them, they die almost universally and they often re-aranges the landscape. Godzilla's usually occur after a brief chargeup period. Gamera's does as well, but also has other nasty side effects--like cutting him off from humanity and draining the health of the earth itself.
* The surprisingly good Roger Corman B-Movie ''Battle Beyond The Stars'' (''Seven Samurai'' IN SPACE) features a weapon called the "Stellar Converter". It appears to be exactly what it says on the tin, in that when the villain uses it, the weapon appears to ignite an inhabited planet into a small white dwarf star.

[[/folder]]

[[folder: {{Literature}} ]]

* The Dr. Device/Little Doctor in ''[[EndersGame Ender's Game]]'', so named because it was developed as the '''M'''olecular '''D'''isruptor Device. Somewhat different in that it has a short-range area effect rather than being a projectile or beam, but this field can start a chain reaction of apparently unlimited size - it obliterates everything in its area of effect, everything ''next'' to its area of effect, everything next to that, and so on until it hits an area without enough mass to continue the chain-reaction. Ender asks if the device could be used on a planet; the response is a horrified shudder. [[spoiler:And then he tries it on the Bugger homeworld, annihilating it in a single shot.]]
* In E.E. "Doc" Smith's novel ''Grey Lensmen'', we are introduced to the sunbeam, a weapon which concentrates into a single beam '''the entire radiant energy output of a star.'''
**Also, throwing planets at things (or crushing them between two planets). Later, because even that isn't quite powerful enough, we get [[spoiler:planets from an alternative universe with a velocity greater than that of light]] thrown at enemy-held planets.
*** The LensmanArmsRace is a trope for a reason.
* In one of John Campbell's Arcot, Wade and Morley novels, the titular heroes come up with the molecular motion gun, which turns the random molecular motion of an object (heat) into motion in a single direction. The ray is catalytic in nature, so basically any object it is used on, from a city to (in one chapter) an entire star, is a) frozen to absolute zero, and b) hurled off in any direction desired.
* {{Stephen Baxter}}'s Xeelee stories are nothing but greater and greater Wave Motion Guns. Wormhole weapons are used to conquer Earth. Humanity escapes this after accidentally using some old Xeelee tech to hasten the life of a sun. We rebuild and conquer everything in the Galaxy except the Xeelee at the center. Weapons include neutron stars being used as bullets. This gets worse. The Xeelee had a greater foe. The photino birds are a form of exotic matter lifeform going around blowing up every sun in the universe that's not already a red dwarf in order to make the universe more palatable (for them). In response the Xeelee manipulate the entire history of the Universe to escape, sending fortresses in every galaxy in the universe to the Big Bang and spending all 15 billion years of history building a portal to other universes.
* The most powerful weapon in the ''{{Antares}}'' novels is probably the antimatter projector, which fires a continuous stream of antimatter. Not only is it pretty much unbeatable, but it's standard armament for both human and alien blastships.
* StanislawLem's ''Invincible'', while having a crew that was at best MildlyMilitary, certainly didn't lack in firepower. Even its recon planes packed an antimatter gun, and the starship herself could, quoting from the novel itself, "boil a medium-sized sea".
* This, however, takes a backseat to a couple of SpaceOpera examples. Ed Hamilton's "The Star Kings" featured a ''Destructor'' -- the gun that destroyed the ''space itself''. It ate up a good part of a starship's energy balance, but where it hit, nothing remained.
* On the other hand, in Sergey Snegov's "The Men like Gods" people used similar device ''as an engine''. While not initially being [[MildlyMilitary all that warlike]], they found the side effects of their favourite space drive [[SuperweaponSurprise quite useful]] later, when rather unfriendly aliens appeared.
** The heroes went on with ''[[DefeatMeansFriendship befriending]]'' the crap out of said aliens, in the best [[MahouShoujoLyricalNanoha Nanoha-style]], and then teaming with them, when the next bunch of the enemies arrived. THREE TIMES. Interesting folk, SpaceOpera writers...
* In LarryNiven's KnownSpace stories, there exists several of these:
** In ''"Ringworld's Children"'', human starships are armed with a weapon called simply "The Anti-Matter Bullet"; guess what it fires.
** In ''"Protector"'', the Brennan-Monster destroys an entire fleet of Pak warships with something he calls the Finnagle Gun. It fires bowling-ball-sized pellets of pure neutronium.
** In ''"The Man-Kzin Wars"'', the Terran system is defended from invaders by the Mercury Laser; its a laser the size of the equator of the planet Mercury, and is capable of destroying ships as far out as the orbit of Neptune. It turns out that while a purpose-engineered Wave Motion Gun is fun in itself, [[{{SuperweaponSurprise}} lasers powerful enough to drive solar sails]] are just as grand.
** And in his short story ''"The Warriors"'', a human colony ship uses [[WeaponizedExhaust a photon drive as its means of propulsion]]. When a Kzinti warship pulls up near them with hostile intentions, the crew has no idea what to do as [[CrystalSpiresAndTogas war and weapons haven't been seen on Earth for hundreds of years now]]. The captain has a [[ActualPacifist disturbingly sick idea]] and turns the ship so the engine faces the Kzinti ship and turns it on, which slices the Kzinti ship cleanly in two.
** There are a lot of [[SuperweaponSurprise devices]] like the previous two examples in the era of peace leading up to the first Man-Kzin War. Mining lasers for slagging asteroids that can slag warships just as easily, light-sail launch cannon that can fire coherent beams to the orbit of Neptune, mass drivers for sending material between planets that can just as easily sling chunks of metal at high speed towards invading ships, highly efficient photon drives that double as super-lasers, super-powerful fusion drives for interplanetary and interstellar ships that can spray streams of hot plasma over planetary distances. All of which were key in humanity's overwhelming victory over the Kzinti warfleet in the first Man-Kzin War, since Kzinti telepaths had reported that "humans have no weapons at all." It's all but WordOfGod that all these technologies [[GovernmentConspiracy were created with a dual-purpose in mind by the paranoids of [=ARM=]]].
** Let's not forget the Soft Gun, which is an multi-function alien device that can, in one of its modes, convert matter into energy at a distance. It should be noted that this is a ''hand-held'' device.
** There's also the ''Wunderland Peacmaker'', based on an alien 'excavation tool', it creates two areas, one that suppresses the negative charge of electrons, and one that suppresses the positive charge of protons. [[HumansAreBastards The humans made an]] [[KillSat orbital version]]. After it was used, they renamed the planet '''Canyon''' after it's defining feature.
** It turns out that [[spoiler: Ringworld]] has a laser that [[spoiler: is generatd in a star. It shoots a Solar Flare sized lazer larger than planets.]]
*In Jack L. Chalker's "Well World" series the entire universe is actually a simulation running on a gigantic computer called the Well of Souls. Humanity figures out how to hack it to a minor degree and builds "Zinder Nullifiers" for use in a major intergalactic war, weapons that basically reformat a large region of space into a default empty vacuum state. The war gets a bit heated, the Nullifiers are overused, and the Well World starts suffering a progressive memory fault that will eventually destroy the entire universe unless our intrepid heroes are able to get into the Well of Souls' control center to fix it.
* Colin Kapp's ''The Chaos Weapon'' was powered by pulling a '''star''' into its ammunition feed; it used a ring of black holes to focus the resulting beam. What this beam did was manipulate entropy: if something bad would '''ever''' happen in the target area, the Chaos Weapon could make it happen '''NOW'''. Lightning strikes, dams giving way, earthquakes.... You say that star's not due to go nova for another twelve million years? Guess what.
* The various [[{{Precursors}} Precursor races]] in AlanDeanFoster's ''HumanxCommonwealth'' series developed a number of these, especially the Tar-Aiym and Hur'rikku who fought a galaxy-spanning war 500,000 years in the past. One weapon (the Krang) requires a planet-sized power source and creates miniature artificial black holes, while another (the anticollapsar weapon) creates ''reversed'' black holes made out of pure antimatter. The latter's unique power source has a charging time on the order of thousands to hundreds of thousands of years, quite possibly a record in fiction.
** It gets better in the GrandFinale, ''Flinx Transcendent''. Flinx finds a roaming Tar-Aiym [[LostSuperweapon weapons platform]] that has ''hundreds'' of Krangs, which when fired simultaneously can cross the intergalactic void and destroy entire star systems from the backlash alone. Even [[TheWorfBarrage that isn't enough]] to affect the UltimateEvil, though, so he goes and locates a Xunca superweapon that extends across multiple dimensions and pulls in several million galaxies' worth of energy.
* The 'Hell-class' weapons from Alastair Reynold's RevelationSpace. Some can blast big holes in a planet's crust. Others can ''destroy stars'' (or so we're told). [[spoiler: The Inhibitors get some as well; how does a ''stellar flamethrower'' sound?]]
* The ''Andalite Chronicles'', a side-story of {{Animorphs}}, mentions that a dome ship's main shredder is a laser "as thick as a tree trunk, capable of blasting chunks off a planet".
* The ''{{Halo}}'' novels have the Magnetic Accelerator Cannon, or MAC, which are a type of railgun that fires (depending on the book) ferrous or depleted-uranium slugs, and are initially the only human weapon (other than nuclear bombs) that can pierce Covenant ship-based shields.
* Stephen Donaldson's ''The Gap'' series features the awesomely named Super-Light Proton Beam cannon, which, in addition to being stupendously powerful, is the only weapon in the series capable of dealing DeathFromAbove to planets... ''we're told''. However, despite essentially being the series' main antagonist for the last three books out of five, the weapon is never (succesfully) fired. A sort of a reverse Chekhov'sGun.
** Also, despite its supposed usefulness, the good guys do not have one - even at the space police headquarters at Earth.

[[/folder]]

[[folder: {{Live Action TV}} ]]

* The main weapon of the ''Excalibur'' in ''{{Crusade}}''.
** Arguably, the Vorlon planet destroyer ship in ''{{Babylon 5}}''.
* The primary weapon of ''{{Lexx}}''. (In fact, the ''only'' weapon of The Lexx.) Being a living ship and the most powerful weapon in two universes, it's not like the Lexx needs additional firepower. As an added bonus, the CGI effect of the Lexx firing even ''looks'' like a wave front.
** Also, in the very first episode in the very first minute, there's a rather hellish weapon that erradicates the surface of a planet in about 5 shots.
*** That would be the Foreshadow, the flagship of His Divine Shadow.
* In ''StarTrek TOS'', the episode The Doomsday Machine features a giant space carrot that goes around mindlessly destroying planets. The episode makes a very un-subtle allusion to the H-bomb.
** In a stroke of {{Irony}}, it is then stopped by essentially a ''real'' H-Bomb - [[spoiler: impulse engines overload]].
* In ''StarTrekTheNextGeneration'', the navigational deflector dish of the Enterprise-D is modified into one of these on two separate occasions, most notably during "The Best of Both Worlds", where it was used against a Borg cube. [[spoiler:It didn't work. It also didn't work the only other time it was used, to try to free the ship from a subspace anomaly. Other than its complete failure in field testing,]] the deflector "cannon" featured all of the ''drawbacks'' of the Wave Motion Gun trope, including long charge times, potential damage to the ship from the firing process, and even the necessity of clearing all the decks surrounding the dish to avoid irradiating the crew. This editor wonders whether the weapon would have fared better if tested on the Enterprise's sister ship... the USS ''Yamato''.
** In the ExpandedUniverse novel ''Vendetta'', the USS ''Repulse'' uses the deflector dish weapon to blow another Borg ship to bits. To be fair, though, that cube had already been heavily damaged in a battle with a spaceborne version of TheJuggernaut.
** Conversely, the future Enterprise in "All Good Things" features an enormous phaser cannon on the bottom of its saucer section which can destroy powerful Klingon warships with a single shot; it does not appear to cause significant power drain or require a long reloading time.
** In ''StarTrekVoyager'', the Doctor uses a weapon called the "Photonic Cannon" during one of his daydreams. Obviously the Voyager has no such weapon, but [[spoiler:they later pretend to in order to scare off a superior foe.]]
** Species 8472 can combine the output of nine ships into one single [[EarthShatteringKaboom wave of destruction]]--which even ''looks'' like a wave.
* In ''PowerRangers'', the heavier HumongousMecha tend to have these. The drawbacks usually aren't mentioned... however, such an attack ''is'' usually only used as a finisher or after conventional weapons have already been tried. Rangers themselves can often combine their weapons for a smaller one of these.
* The Ori beam weapon in ''{{Stargate SG-1}}'', and subsequently the Asgard beam weapon mounted on Earth ships.
** These aren't very good examples of the trope at all, as the weapons don't seem to drain the energy very levels too much (probably not in the least for the Ori toiletcruisers), and the Asgard weapons [[spoiler: require several hits from two ships to kill a Aurora-class cruiser]]. Now, the beam Anubis' mothership uses to [[spoiler: destroy Abydos]], on the other hand...
* In Gene Roddenbery's ''{{Andromeda}}'', the big bad has ships equipped with Point Singularity Projectors. Essentially capable of firing off black holes which measure several dozen meters across and can blow holes in anything, from spaceships to planets, to a sun.
* The Hand of Omega, in ''{{Doctor Who}}'', which isn't even supposed to be a weapon. In the new series alone, the Delta Wave, the Reality Bomb... And that's just for starters. This a series where the final shot of a war ''erased two races from history''.
* In ''{{Buffy the Vampire Slayer}}'', Buffy, Xander, Willow, and Giles mystically combine to become a Super-Slayer capable of reality-bending feats and destroying the Big Bad. However, they can never use it again as doing so offends the First Slayer, who tries to kill them in their dreams in retaliation.
* In the old German series ''Raumpatrouille'', the starship has the aptly-named "[[ThereIsNoKillLikeOverkill Overkill]]" weapon capable of blowing up small planets.

[[folder: {{Real Life}} ]]

* [[http://en.wikipedia.org/wiki/Boeing_YAL-1 Boeing YAL-1 Airborne Laser]]. I mean, [[http://en.wikipedia.org/wiki/File:Airbornelaserturret.jpg look at the size of the friggin turret]]!
* The US Navy's upcoming [[http://www.onr.navy.mil/emrg/electromagnetic-railgun.asp 64 megajoule railgun]]. Mach 5, 200 mile range, pinpoint accuracy and sucking down most of the ship's power to fire. [[http://gizmodo.com/351467/navy-rail-gun-test-destroys-everything-it-touches-at-5640-mph Yep]].
** Except, the railgun ''isn't'' an energy weapon. It's still a [[KineticWeaponsAreJustBetter kinetic weapon]], which fires a projectile.
* A hypothetical real-life Wave Motion Gun would be [[http://www.projectrho.com/rocket/rocket3x.html#shapedcharge Nuclear Shaped-Charge]] weapons. They've never been built([[OrIsIt or have they...?]]), but they are possible. Basically, you take the might of a Nuke, and instead of wasting it in an undirected explosion, you convert it into a ravening plasma beam, as hot as a star's core. Simply awesome.
* Some space objects (Quasars, dying supergiants, neutron stars colliding)can produce what is called a Gamma Ray Burst, basically two ''humongous'' lasers shooting out from opposite sides. The scary part? ''[[TheWorldIsAlwaysDoomed At least one star capable of producing a GRB is pointed at the Solar System, is extremely old, and may fire one off in the next 200,000 years]].'' Talk about massive FrickinLaserBeams.
** The above entirely fails to convey the sheer devestation these things cause. If a Gamma Ray Burst ''were'' to hit the Earth, the atmospere would boil away and everything down to the bacteria would be dead within minutes. There is a very real chance that this would render Earth entirely uninhabitable (by ''anything'') forever.

[[folder: {{Tabletop Games}} ]]

* Nova Cannons in ''{{Warhammer 40000}}''.
** Not to mention the Blackstone Fortresses' combined-shot star-killing trick, or the aptly named Planet Killer.
*** Even the single ship version of the Blackstone Fortress' Warp Cannon probably counts.
** Planetside, the Shadowsword's Volcano cannon probably counts, as it is immensely powerful - it is a Titan gun, after all - but drains the capacitators, rendering it unable to move or fire again until they have recharged.
* Spinal mount particle accelerators and meson guns in ''{{Traveller}}''.
* Maulers in ''StarFleetBattles'', a ship built around a Wave Motion Gun and its associated power systems. Very effective in the hands of a skilled player with a grasp of the right tactics to employ them to their best, [[AwesomeButImpractical less so otherwise]].
* The Godspear of the [[CoolShip Five-Metal Shrike]] from ''{{Exalted}}''. It does, effectively, infinite damage at ground zero. If you have the right charms, though...[[BeyondTheImpossible you can block it.]]
* ''YuGiOh'' has a couple of these, such as the much-loved/loathed/feared/dreaded [[ExactlyWhatItSaysOnTheTin Wave Motion Cannon]], which charges up as the turns go by and able to be removed from the field to blast the enemy for 1000 damage per turn it had charged, [[KillSat Sattelite Cannon]], a monster that cannot be killed by anything below a certain level and possessing a similar charge-up ability (1000 ATK per turn, loses it after it attacks), and more than one of [[TheRival Seto Kaiba's]] signature monsters -- [[CombiningMecha XYZ Dragon Cannon]] uses this whenever he discards, and Blue-Eyes White Dragon happens to have this as an attack. [[http://yugioh.wikia.com/wiki/Burst_Stream_of_Destruction Which was later made into a card,]] namely a [[ShockAndAwe Rai]][[RocksFallEveryoneDies geki]] {{Expy}}.
* Although ''{{Aberrant}}'' characters are generally played at a much lower level of power, akin to your average MarvelComics character, the game has Quantum powers at levels 4, 5, and 6 (which could only be acquired after a very long campaign if you play by the standard rules.) One of the level 6 powers is Quantum Inferno which allows the character to fire a Quantum Bolt capable of punching a hole, hundreds of kilometers wide, clean through the planet (which needless to say is the immediate predecessor to the planet's destruction.)

[[/folder]]

[[folder: {{Video Games}} ]]

* Just about every fighter in the ''{{R-Type}}'' series has one, complete with charge up! It's even CALLED a Wave Cannon!
** The giant warship in stage 3 of ''{{R-Type}} Final'' has a giant version of this, capable of [[EarthShatteringKaboom destroying entire planets]].
** Super-powerful Wave Cannons a common phenomenon in the R-Type universe (the boss of stage 1 in Delta, Moritz-G, has one, the 'boss' of stage 3 in Delta has two even larger ones, the boss of stage 1 in Final also has one... and so on). A few that're worth noting would be the Utgarda Loki in Tactics, and the Giga Wave Cannon in Final, that can be charged for 7 loops, and instantly destroys any enemy that can die in any difficulty, ''and'' it goes through physical obstacles like, say, meteors. In fact, the 'Final' Wave Cannon used to destroy the Bydo Core in stage F-A basically looks and acts like a fully charged Giga Wave Cannon.
**Final states that the "planet buster wave cannon" is the same as the fighter mounted wave cannons, but [[UpToEleven 100 million times more powerful]]. Given the amount of energy needed to destroy a planet, that means that the fighter-mounted wave cannons have a maximum output somewhere in the region of 100 ''teratons''. NoKillLikeOverkill indeed.
* The "Phase Transit Cannon" from ''WingCommander 2'', and the Nephilim-derived fleet killing plasma cannon equipped on the mothership of ''WingCommander Prophecy.''
** The main gun of the ''Behemoth'' from ''WingCommander III'' fits this trope perfectly--the ''Behemoth'' being a huge honkin' cannon with a ship wrapped around it.
* The siege cannon in the RealTimeStrategy game ''{{Homeworld}} Cataclysm''. It takes several real-time minutes to charge, and even when the fire button is hit, the shot takes an extra few seconds to charge up.
** Another weapon seen in Cataclysm, the Repulsor Cannon that can be fitted to Archangel Dreadnoughts [[spoiler:and forms the primary weapon of the Nomad Moon in the final single-player mission]] might be considered one of these, for all that it's actually not all that useful.
**Also, the Dreadnought and [[spoiler:Sajuuk]] from ''Homeworld 2''.
* In ''SuperRobotWars: Original Generation'', the capital ship "Hagane" wields a massive, energy-guzzling [[{{Unobtainium}} Tronium]] Cannon. However, it can be fired with no real recharge time for the ship, and is in fact used often with the 'gravity brake' off so the ship can use the massive inertia in a fancy escape maneuver. The "Hiryu Custom"'s Gravity Cannon and the SRX's Hyper [[strike:Titanic Blasting]] Tronium Buster Cannon also count. Its full name, [[CallingYourAttacks according to]] [[AscendedFanboy Ryusei]], is the Tenjo Tenga Ichigeki Hissatsu ho or Heaven and Earth One-Hit Sure-Kill Cannon.
** ''SuperRobotWars W'' adds the ''Valstork's'' Double Proton Cannon, which can even link with the Valhawk to utilize it's ChestBlaster for even more power. The Dimension Breaker, the Chest Blaster of the Valzacard, by comparison, is it's ''least'' powerful attack, which, by comparison again, is apparently the Valstork's Double Proton Cannon redirected.
* Terran capital ships in the ''StarCraft'' universe are equipped with a Yamato Gun (naturally, named after ''UchuuSenkanYamato''), which fires a massive bolt of energy in exchange for a large chunk of the unit's [[ManaMeter energy meter]]. This is easily acceptable, though, given the fact that the Yamato Gun is the only use for said energy.
* The original ''GalaxyAngel'' games (see ''GalaxyAngelGameverse'') have the Chrono Break Cannon.
* The Eclipse Cannon that first appeared in ''[[SonicTheHedgehog Sonic Adventure 2]]''.
** Also, the Power Laser for Tails' and Eggman's mechs (battle mode and second enemy boss battle only).
* "Moonstone Cannon.... Fire!" from ''SkiesOfArcadia''.
** Whle we're on the subject, [[LunarKnights "Purifex Cannon... FIRE!".]]
* ''FinalFantasyVII'' features a Mako Cannon (inexplicably named "Sister Ray") built by the [[TheManBehindTheMan Shinra Electric Power Company]] for the sake of taking out the [[DeflectorShields impenetrable barrier]] around [[BigBad Sephiroth]]. It is fired only once; Diamond Weapon stands in its way and is is cut through, but returns fire, destroying a fair chunk of Shinra headquarters and apparently killing the president. Despite the interference, the weapon succeeds in destroying said barrier.
** On top of that, the player can acquire a summon that calls a being known as Bahamut ZERO, a gigantic flying dragon that bombards its targets from space with a giant beam of destruction.
*** If used in the FinalBoss battle, which takes place deep underground, this summon ''ought'' to cause even more damage to the planet than the {{BigBad}}'s evil plot would have...but GameplayAndStorySegregation to the rescue!
*** ''Crisis Core'' brings us Bahamut Fury, which destroys (or at least melts) a good portion of the MOON to fire a giant laser at enemies.
** This actually pales in comparison to an even ''more'' over the top attack used by the Guardian Force Eden in ''FinalFantasyVIII'', in which Eden uses the enemy as ''ammunition'' for a beam that is fired into ''another galaxy'', which then ''explodes''. It's also powerful enough to break the 9999 HP Damage Cap, which applies to nearly every other attack in the game.
*** And in that note, the ''FinalFantasyVI'' and ''FinalFantasyVII'' incarnations of [[HumongousMecha Alexander]] fire a laser from their mask; it's relatively thin, but it blows up the entire battlefield.
** And then there's ''FinalFantasyX2'''s Vegnagun, which [[spoiler:Shuyin]] tries to use to destroy Spira. It was originally designed to [[spoiler: bring down Sin, but it was sealed beneath Bevelle when it failed to distinguish friend from foe.]]
***On the subject of Final Fantasy, Sin itself (from FFX) should count, given the damage its Tera Gravitation attack causes to the planet when it is fired.
** FinalFantasyXII brings us the Mist Cannon, which is deployed at the end of the game against [[spoiler:the Rebel fleet, to devastating effect, as it is capable of destroying ANY SHIP IN ONE SHOT.]]
* No mention of ''FinalFantasyV 's'' Soul Cannon and Guardian yet?
* A common staple of ''CommandAndConquer'' games:
** GDI's [[KillSat Ion Cannon]] in the ''Tiberium'' series.
*** Which was exported to ''CommandAndConquer Generals'' as USA's Particle Cannon. In the ''Zero Hour'' ExpansionPack, General Alexis Alexander's Particle Cannons were cheaper, stronger, and ''purple''.
*** That's probably not simply purple, it's just more [[TurnsRed red]] than the blue "common" Particle Cannon.
** ''Red Alert 2'' has the Allied Prism Tower and Prism Tank. The former can be charged up by other Prism Towers in range, while the latter's attack bounces between enemy units.
** The Empire of the Rising Sun in ''Red Alert 3'' has an interesting version in the Wave-Force Artillery. Besides the usual full power blast, it can be turned down to fire more often.
* Possibly Dan Smith's Collateral Shot from ''{{Killer 7}}''. It's the only thing that can kill the Heaven Smile hives and it uses all the bullets in his gun and three vials of blood.
* In ''Rogue Galaxy'', the Dorgenark carries a double-barreled Wave Motion Gun on the front--called, simply, 'The Big Guns'. According to an NPC, they can take out a small planet, and the one time they're used in-game, they live up to the hype.
* You do battle against a Wave Motion Gun in ''SuperMarioRPG'', controlled by the evil ''PowerRangers'' spoofing Axem Rangers on top of their blade shaped CoolShip (if you can call it that) called Blade. It takes 3 turns to charge it up but it has the potential to annihilate your entire party in one turn. Unfortunately, a boss later on in the game has the potential to use this attack every turn.
** ''SuperMarioBrosZ'' shows what happens when this is connected to a [[MacGuffin Chaos Emerald]] from the Sonic games. Even the Axem Rangers themselves are shocked. They don't get to use it again though, because [[spoiler:Mecha Sonic, the BigBad of the series, shows up, takes the emerald in question, and singlehandedly destroys them and Blade]].
*** For the record, what happens is that [[spoiler: IT DESTROYS THE ENTIRE MOUNTAIN RANGE OF YOSHI'S ISLAND.]]
* The ship-mounted railguns in the ''{{Halo}}'' universe definitely qualify, as they require a large chunk of the ship's power supply to operate, and the humans build entire space stations around extra large models.
** The Scarab is equipped with a WMG as well.
** The Titular Halos appear to be weapons of this type as well, given Halo 3's last mission.
** The Spartan Laser.
* In ''{{EVE Online}}'', Titan motherships are equipped with doomsday devices, enormous missiles capable of destroying entire fleets of (player) opponents. Even though it's in the hand of a player, this is a last-resort weapon that can only be used once an hour, prevents the Titan from jumping (effectively escaping) for 10 minutes and a single shot is more expensive than some smaller combat vessels. It's also subject to friendly fire (which limits its use to defensive purposes).
** Before the ObviousRulesPatch doomsdays could be fired remotely, and did not disable jump-drives, making them complete {{Game Breaker}}s.
** In addition, Jamyl Sarum of the Amarr Empire used a [[http://www.youtube.com/watch?v=PKdTJjDnYzE#t=1m30s chaining Wave Motion Gun]] against a Minmatar Titan, destroying it together with it's support fleet. [[spoiler: The gun is LostTechnology, [[MacGyvering MacGyvered]] into a modern ship hull. Firing it requires some {{Unobtanium}} and it ''melts'' the ship from within, including the crew. Suffice to say, it's reserved for [[CutscenePowerToTheMax cutscene]]s]].
** The 11th patch/expansion, ''Dominion'', will modify doomsday weapons to be, in the words of Eve blogger/podcaster Winterblink, "Macross cannons": In exchange for losing the AOE damage, they will do massive damage to a single target via a large energy beam. CCP has also hinted that more doomsday weapons are on the way...
* Every side in ''SupremeCommander'' has an enormous, Tier 3 artillery piece which takes a half hour to build and fires about once ever 10 or 15 seconds to a range of around 10-15km, enough to cross the small and medium maps and get almost across the large maps (the extra large maps are up to 81km). They're really only useful when used by UEF, and then in large numbers to try and take out the enemy's commander.
** The UEF also has a Tier 4 version, which is hideously expensive, has an insane build time, but has unlimited range and much better accuracy then the Tier 3 guns.
*** The Cybrans have their own Tier 4 artillery, which is cheaper, builds faster, does less damage, and fires fast enough to batter down shields in under 20 seconds, but takes obscene amounts of energy and has much shorter range (though it is mobile, barely).
** The Aeon and Cybrans also have tier 4 units that are expensive and slow, but can vaporize everything in front of them with a giant microwave cannon. In the expansion, the UEF got a KillSat with one of these.
* ''{{Crysis}}'' provides a rather hilariously underwhelming example of this technology when [[spoiler: a huge alien space cruiser opens up on a US aircraft carrier, complete with proper "charging" GFX and ominous "buildup" sound. The effect? Several broken bridge windows and some debris on the flight deck. This is made even more ludicrous when the alien behemoth continues the barrage, resulting in no further damage to the ship. One wonders why the aliens didn't just ram the carrier (the cruiser is previously involved in a head-on collision with a destroyer escort, resulting in one sunk destroyer and no apparent damage to the alien vessel).]]
**[[spoiler: The same alien craft also uses the said weapon on the final level of the Expansion Game where it blasts sections of an airfield before moving on to the carrier.]]
**If you'd pay attention, [[spoiler: the alien craft had a protective shield while ramming the destroyer before being disabled by the scientist.]] And less obvious that [[spoiler: there's a captured alien suit/craft in the carrier that the aliens tried recovering in Crysis: Warhead.]]
* The Jehuty gets one in ''ZoneOfTheEnders: The Second Runner'', called the Vector Cannon. It takes an absurdly long time to fire, but rest assured that whatever's on the receiving end of it will die.
* Bungie's ''{{Oni}}'' also features the Wave Motion Cannon, an absurdly BFG that was originally a part of a combat vehicle. It can either shoot a long, laser-like energy beam or launch grenades (and yes, each firing of the energy beam requires a few moments of SuckingInLines)
* To defeat Adam, the final boss of ''Headhunter'', you first need to steal his 'Judgment Cannon', a massive hand-held Wave Motion Gun, charge it up by SuckingInLines, and blast it in his chest, hoping that he doesn't stomp up and hit you while you're vulnerable.
* In ''Space Empires V'', and its predecessors, a weapon available for ships is a literal Wave Motion Gun, which is a powerful, long-range beam weapon.
* The Savior boss's ultimate attack from ''DevilMayCry 4'' is of this variety.
* Moves like Solar Beam, Skull Bash, Sky Attack or Focus Punch from ''{{Pokemon}}''. Focus Punch is a prime example, because it has an appropriate drawback; if the performing Pokémon is hit before it can fire, Focus Punch fails.
** The Hyper Beam-type moves, too, with the charging period afterwards instead of before.
* The #3 ranked assassin Speed Buster in ''NoMoreHeroes'' wields a shopping cart... which ''transforms'' into an all-annihilating Wave Motion Gun.
* ''StarFox 64'' has Gorgon (the "Area 6" boss) with its giant rainbow laser.
** And the Saucererer, with its Katina-base-destroying laser that takes a full minute to charge up.
* In Koei's ''Warship Gunner'' series, basically ''DynastyWarriors'' with battleships, the most powerful weapons in the game are "Wave Guns," which come in several sizes but all of which fire lasers larger than the player's ship (which cause the player's ship to rocket backward thanks to laser recoil) and can sink fleets of enemy ships, yet will do fairly little against the game's island-sized bosses, who can have multiple wave guns and giant, hull mounted instant death buzz-saws.
* In the space flight simulation ''{{FreeSpace}} 2'' most capital ships are equipped with up to a dozen very powerful beam weapons. They have a both visual and audible buildup of 3 seconds and fire beams that can blast straight through other ships. Their diameter is large enough to completely engulf smaller fighters, which are instantly vaporized if they happen to be in the beams path at the moment.
** This can lead to some irritating deaths where your fighter ''just happens'' to be in the path of one of those beams: the capital ship beams do not target fighters, but heaven help you if you decide to fight in between two opposing capital ships, because they hit instantaneously and are therefore ''undodgeable''.
* Subverted in ''TreasureOfTheRudras'' as the Wave Motion Gun was used to kill the existing races on Earth.
* The TEC's Novalith Cannon in ''SinsOfASolarEmpire''. The best way to describe it is that it does to planets what nuclear bombs do to cities. A single hit will depopulate all the but the most heavily populated planets. For those, you need two missiles. Oh, and there's fallout.
**Also, one of the Advent capital ships has one of these as its "capstone" ability, Cleansing Brilliance.
** Likewise, the Vasari Kotsura Cannon applies. Not sure about the Advent's Deliverance Engine, since it essentially fires weaponized love. Kinda.
* When you pilot the Super Dimensional Gear for a single battle in ''{{Xenogears}}'', you can opt to fire the Yggdrasil cannon for 9999 damage. The only drawback is that it costs 9000 of your 9990 fuel.
* ''{{Xenosaga}}'' has several. There's the Phase Transfer Cannon KOS-MOS uses, for starters. Then the Dammerung has a huge version called the Rhine Maiden designed to be fired [[ConvergingStreamWeapon in conjuction with three other ships]].
** Note that this is huge in comparison to the Dammerung itself. Also note that the Dammerung is ''huge'', with dimensions measured in ''kilometers''.
* Heavy Beam-class weapons in ''{{Sword Of The Stars}}'', ranging from the Heavy Combat Laser to the (anti-matter) Cutter Beam. Firing one on a planet leaves a large canyon, and Dreadnaughts can carry up to ''fourteen'' of them.
* ''{{Iji}}'' gives us the Phantom Hammer, a ship-mounted energy cannon that, used in numbers, can either render a planet uninhabitable, or destroy it completely. A shot from one of these can pierce through several kilometres of solid rock. The final boss carries a more compact version; [[OneHitKill it's no less powerful]].
** If Iji cracks together the two most powerful pieces of Tasen and Komato nanoweaponry, she gets the Velocithor, a hand-held Wave Motion Gun capable of blasting through enemies and walls alike, and is instrumental in a very specific bit of DungeonBypass.
* In the RTS ''RiseOfLegends'', the Cuotl race have practically built their entire society off of Wave Motion Guns. Oh, and machines made of stone. But really the FrickinLaserBeams.
* [[TouhouProject Marisa Kirisame's]] Master Spark and Final Spark spellcards certainly count, whether she's using them as your [[http://i41.tinypic.com/n154ox.png ally]] or your [[http://i39.tinypic.com/10gn1c3.jpg enemy.]]
** Yuka Kazami counts as well, since she's actually the ''creator'' of Master Spark, which Marisa [[strike: stole]] copied and modified.
** Don't forget [[http://www.youtube.com/watch?v=kofnEdB8Blc Mima]].
* The ''DwarfFortress'' LetsPlay [[http://lparchive.org/LetsPlay/Boatmurdered/ "Boatmurdered"]] features "Project Fuck The World", a device which ''redirects a stream of lava'' onto [[strike:anyone attacking the fortress]]'' the whole world.''
** Ballistae probably also qualify. A plain wooden ballista bolt will travel in a straight line through virtually anything, likely instakilling anything (friend or foe) that gets caught in its path and traveling forward until it hits a wall or runs off the map. Tipping it with adamantine? Oh jesus.
* Samus Aran's Zero Beam, her [[LimitBreak Final Smash]] in ''SuperSmashBrothers Brawl''. It consists of an all-consuming, screen-filling beam that will (very likely) [[ATwinkleInTheSky instantly KO]] anyone standing in its path. Unfortunately, it's so powerful it [[ExplosiveOverclocking breaks apart her]] [[FanService Power Suit]].
** While we're on the subject of SSBB, in the story mode, the Subspace army manages to pull what amounts to a huge gun with mounted turrets on its side out of subspace. Its about 10x the size of the Halberd, the annoying ship you chase for most of the game, and that ship is already ''hundreds of feet long''. This floating gun fires a huge energy blast that pushes the ''entire world into another dimension!''. Shortly destroyed by Kirby, riding a tiny Air Ride Machine. Miniature airplane trumps world crushing battleship. Who'da thunk it.
* The Mana Cannon from ''TalesOfPhantasia'' and its prequel, TalesOfSymphonia.
* The Capitol Ships from ''EmpireEarth'' space age epoch has the [=DBOD=] or [[ExactlyWhatItSaysOnTheTin Devastating Beam of Death]]. It uses the game's ManaMeter so takes a long period of time to recharge. [[AwesomeButImpractical Longer than the duration of most space battles in fact]]. The prototype of the Capitol Ship was named, appropriately enough, the [[UchuuSenkanYamato Yamato]].
* ''MasterOfOrion II'' has a weapon called the Stellar Converter, which can only be mounted on ships of Titan class or larger. It's the most powerful beam weapon in the game, and can indeed be used to [[EarthShatteringKaboom destroy entire planets]].
** It can also be built on planets as a defensive weapon.
** With enough miniaturization, one can fit a Stellar Converter on a Battleship. However, by that point in the game, one would be forgiven for asking "why bother". If the player has survived to that stage in the game, using SC-armed battleships is just demonstrating VideoGameCrueltyPotential.
** Note that the Stellar Converter from the second game shares only the name and enveloping damage with the first game's Stellar Converter. In the original ''MasterOfOrion'', the Stellar Converter is merely longer-ranged weapon, with no EarthShatteringKaboom effect on planets.
* You don't get to use one in ''{{Gradius}}'', but they certainly get used against you. The idea generally isn't to dodge them (which is fairly easy) but to keep from getting forced into a very bad place by the beams (which isn't).
* The ''NavalOps'' series of games featured the Wave Motion Gun as a naval combat weapon. And is used by several bosses.
* ''Fraxy'' gives you the Laser in 3 different sizes and the Sonic Wave, which ''pushes people away''.
* ''Star Wars: Empire at War'' and ''Forces of Corruption'' expansion: First and foremost: Both Death Stars. Then, there's the plasma cannons of the Zann Consortium space stations, Aggressor-Class battleships, and MZ-8 tanks. Captain Piett's Star Destroyer (the Accusor) also gets a Proton Beam weapon in both games.
* Not a laser, but ''[[AceCombat Ace Combat 6]]'' has the giant railgun, Chandelier as its FinalBoss. It normally takes a long time for it to fire one of its shots (about a minute and a half between "Stauros Preparing for launch" and the giant flash of the cannon firing), but when the crew realizes all is lost, failing to take it out then and there leads to the cannon firing 10 shots (and failing your mission) in a row before it collapses.
** And then there's the Excalibur in ''Ace Combat Zero'', which is a laser, the Arkbird's laser cannon in ''Ace Combat 5'', and the Stonehenge railgun array in ''Ace Combat 4''.
** ''Ace Combat 3'' has Rena's X-49 Night Raven, with a laser that can destroy an island in one shot. [[CutScenePowerToTheMax The playable version]] is toned down though.
* ''[[ArmoredCore Armored Core 4 and For Answer]]'' have the Kojima cannons, massive [[AppliedPhlebotinum Phlebotinum shooting]] beam weapons charged by SuckingInLines, that if they actually hit are an instant kill. Unfortunately, outside of two missions in for Answer,they're [[AwesomeButImpractical useless]].
** And in ''For Answer'' there's the Assault Cannon, [[NamesToRunAwayFromReallyFast Lethaldose]], a Kojima Cannon of immense power that instead of having the traditional charge time of a Kojima Cannon, it uses your [[DeflectorShields Primal Armor]] instead, which then takes a long time to recharge.
* ''G-Darius'' has the Alpha (player-fired) and Beta (boss-fired) beams. The scary part is that they can ''absorb each other'', and by doing so become ''larger, more powerful, and longer lasting''. The beam up top is a player-fired Alpha Beam that has absorbed no less than four Beta beams. Enemies must be captured and consumed in order to fire your Alpha beam, and certain powerful enemies will make your Alpha beam more powerful.
* In ''{{Spore}}'', a player who has made certain choices progressing to the space stage will gain the racial ability to unleash the Gravitation Wave, which will destroy all structures on a planet. Anyone can research a planet-killing laser, which will ''really'' torque the neighbors off.
* This is in ''SpaceChannel5'', of all series. Everyone you saved helps you charge up a super huge laser to take out Blank/Purge depending on which game you're playing. However, you have to hit all three "chus" that the villain gives you, or it's the bad ending for you!
* In the ''ThunderForce'' series of games, the Rynex-class starfighter can be upgraded with the Thunder Sword that requires several seconds for the spherical CLAW drones to charge up to full capacity and fires a huge beam with a comparative short range that will annihilate standard enemies in its path and can inflict heavy damage on Boss encounters.
* In several ''{{Kirby}}'' games, Kirby gains the power Crash. This power will destroy anything on screen, provided it is not a boss or a miniboss. Fortunately, this power can only be used once, preventing it from becoming a GameBreaker.
* The X space combat series has the PSG, which ''is'' a GameBreaker. Instead of firing a single energy bullet like most weapons in the game, it fires an expanding wavefront that is actually more deadly against capital ships, since it can hit them multiple times with a single shot. In X2TheThreat a single fighter with three Beta PSGs could destroy almost any ship or station ''en masse''. And then there's the Paranid Zeus, which can mount ''eighteen'' of the things...
* ''Mystical Ninja Starring Goemon'', on the N64. A surreal fantasy-action-adventure set in semi-mythological semi-feudal Japan, like a simplified Ocarina of Time but with a seriously twisted sense of humour. Some of the bosses are giant alien war mecha that you fight from the cockpit of a giant war mecha of your own called Impact, which looks like a giant grinning robotic Goemon. Impact can charge up a huge energy cannon by causing damage to a boss with conventional attacks; firing this cuts to a cool exterior shot of the beam slamming into the boss and knocking it backwards. Three or four shots of the Impact Cannon are usually sufficient to do away with even the end-game boss, which is effectively a Death Star in the shape of a giant peach and has a wave motion gun of its own...
* ''Front Mission 3'' has the Heavy P-Gun, a prototype beam weapon that exists on two bosses [[spoiler: and can also be acquired by the player through a subquest]]. It's capable of destroying most wanzer body parts in one shot, often resulting in a one-hit KO against a target, but the action point cost to fire it is so high it often can only be fired once every other turn.
* In ''{{Astro Boy}}: Omega Factor'', you have the Arm Cannon (mentioned above in regards to the AstroBoy anime & manga series), which, when fully upgraded, has an area that takes up around half the screen. The game even identifies this in the introductory stage as Astro's strongest weapon.
* In ''DeadSpace'', the [[{{BFG}} contact beam mining laser]] can completely vapourize a non-boss Necromorph monster in one shot, give or take a limb. It requires at least five seconds to charge up.

* In ''BobAndGeorge'', Dr. Light has a Wave Motion ''[[http://www.bobandgeorge.com/archives/index.php?date=051008 BB Gun]]''. It requires three hours of charging and half the power of a city, but it can accelerate a BB to ''relativistic speeds''. It's the perfect thing to use on gnomes. When George asked why he never used it before, Dr. Light had only this to say:
-->'''Dr.Light''': Jesus, George, it's just a harmless BB Gun!
* Ship to ship combat in ''{{Angels 2200}}'' seems to consist of capital ships firing their particle beams, powerful laser cannons that can ''[[http://andreas-lenz.de/angels2200/comic.php?show_image=comic/part6_397.jpg blow right through]]'' another ship, at one another, then letting the fighters duke it out while they wait for the beams to recharge.
* Really, How can we get this far without mentioning [[http://www.nuklearpower.com/2001/03/20/episode-007-kamehameha-or-something/ Black Mage's]] [[http://www.nuklearpower.com/2001/03/23/episode-008-adventurers-1-giant-0/ Hadoken]]?

* The {{BFG}} (binary fusion generator in the show, but we all know what it really means) on the Watchtower in ''JusticeLeagueUnlimited''.
* The flagship of the Irken fleet in ''InvaderZim'', The Massive, has one of these as its main weapon. Also seems to be present on their HumongousMecha.
** Both on the Megadoomer Stealth Assault Mech and the Maimbot. Also worth mentioning is the "Death Wave Cannon" mentioned by the Tallest in the beginning of episode Hobo 13. Although never shown in action, this cannon seems to be a Wave Motion Gun of its own.
* ''MegasXLR'' pulls out the WaveMotionGun, ''[[UchuuSenkanYamato Yamato]]'' and all, in the first episode of the show. Later, it pulls out the ''{{Macross}}'' gun, too.
* The ''Malevolence'', General Grievous' flagship from ''StarWarsTheCloneWars'', is equipped with a pair of gigantic ion cannons that each produce a blast so huge that they can hit an ''entire starfleet''. It's a bit different from the standard Wave Motion Gun, though, in that it only disables enemy ships, rather than destroying them; the ship then actually finishes them off with its [[BeamSpam immense array of turbolaser turrets]].
* The titular ''IronGiant'' has one in it's chest.

* ''Ankh Robot Gunchest'', naturally, [[ExactlyWhatItSaysOnTheTin has a pair of guns on his chest.]] Oh, but they're no ordinary guns, they fire pretty big beams. When he finally makes use of them, it's pretty sweet.
