"I have traveled far and seen much. Yet nothing warms my heart so much as the sight of a gun so massive that its fury makes the very world tremble."
First Captain Lysander of the Imperial Fists, Warhammer 40,000

The Cool Ship needs an equally cool weapon. If it's a sufficiently humongous Cool Ship, it will be equipped with a Laser Beam on steroids: the Wave Motion Gun — an enormous Ray Gun 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 blowing up an entire planet. It doesn't necessarily have to even hit; if you're too close, the sheer energy bleeding off from the beam can be deadly. And don't even think about trying to waste your time with puny Deflector Shields — it'll just punch right through 'em.

Frequently, the Wave Motion Gun is made of Lost Technology, or is 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) are ready to fire. Invariably, just before firing, The Captain has to order the attack.

Naturally, such Superweapons tend to have built in Power Limiters in universes where the power level of everything isn't cranked up. Wave Motion Guns usually require a significant charging period before firing and re-charging/cooldown afterwards (occasionally depicted by Sucking-In Lines; the Wave-Motion Tuning Fork is a popular subtrope used for visual effect). They can be Too Awesome to Use or Awesome, but Impractical. These weapons can often be the weaponized equivalent of a Dangerous Forbidden Technique, especially the most powerful varieties. Some require Explosive Overclocking of the power grid they're attached to, making them risky to use. Sometimes they draw so much power that everything else has to be shutdown to charge them. Others require ... unconventional ... power sources, or they may be a Nuclear Option with risks of heavy collateral damage.

This sort of weapon is frequently mounted on a Kill Sat and is likely to be fired using converging streams. If it's built into a famous real-world location, then it's a Weaponized Landmark. If the bad guys have one, it's a Death Ray. When it's built into the ship so that it's always pointed straight forward, it's a Fixed Forward-Facing Weapon. Kamehame Hadoken is the equivalent of this trope for characters who use Ki Manipulation, Functional Magic, Supernatural Martial Arts, or some other form of superpower. For dragons, it's a Breath Weapon. Facing one of these on foot often involves a Corridor Cubbyhole Run.

    Anime & Manga 
  • Space Battleship Yamato: The eponymous main weapon of the Yamato. Notably, the original Wave Motion Gunnote  itself wasn't just a heroes-only weapon: by season 2, most ships in the Earth Defence Force carried one (some had two), and once exposed to the Wave Motion Gun, everyone else tried to copy or modify one. Desslok/Desslar 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.

    Interestingly, the Wave Motion Gun was not treated as something invincible: at the end of the first season, Desslar's one was reflected back at him, and in the second season we have three different incidents of Wave-Motion Guns utterly failing in their job (first was the Comet Empire's vanguard fleet flagship firing her Magna Flame Cannon while inside Saturn's ring, only for the energy beam to explode against the rings' particles, giving Earth's fleet the time to reach their weapons' range and annihilate the vanguard fleet; then the Earth Defense Force fired ALL their Wave Motion Guns at the Empire's comet fortress, but failed to do any damage; third was the Yamato finding herself attacked again by Desslar and charging the gun, only for Desslar to mine the space before the muzzle and get a good laugh as the Yamato couldn't fire without being destroyed by her own weapon).
  • Space Battleship Yamato 2199 ups its lethality to ridiculous levels, showing that it's capable of wiping out a continent the size of Australia. Later, when the Yamato has to deal with an enemy base on Pluto, blowing up the whole damn planet is considered a viable option. No Kill like Overkill indeed. 2199 even gives the weapon a longer name: Dimensional Wave Motion Explosive Compression Emitter (though the cast still use the term Wave Motion Gun in practice). And they even explain how it works: by generating Micro Black Holes out of the power from the Wave Engine and harnessing their ability to emit Hawking Radiation bursts, which is actually what shoots out of the gun's barrel.

    It also becomes a point of morality in Yamato 2199, where Starsha was horrified that the Star Force had weaponized the Wave Motion technology and almost didn't give them the Cosmo DNA as a result. This was because the Iscandarians themselves had developed Wave-Motion Guns before, and went kinda Drunk on the Dark Side (unlike the Yamato crew, they didn't balk at blowing up planets with theirs).
    • And you can totally see her fears manifesting in a time of crisis. There was an artifact of activating the Cosmo DNA that saved the earth, it left a dimple in space and time called the Time Vault, where time ran much faster inside than out. This allowed Earth to build and field enough ships to - barely - withstand the overwhelming onslaught of the Comet Empire's fleet. But this survival was slowly costing the peoples of Earth their humanity.
    • Notably, Bandai Namco were effectively ordered by the production crew, for its appearance in Super Robot Wars V, to use Applied Phlebotinum to disable the Wave Motion Gun for practically all of the game, purely to keep that moral code intact. It's only used unrestricted in two scenarios — the final battle against the Invaders (since they're willfully-evil beasts who would eat every living thing in the universe given half the chance), and the last stage in the game, where it is the single most devastating weapon on the field, being able to, with the right commands, One-Hit KO the final boss's entire force!note 
  • Likewise Space Carrier Blue Noah, the Spiritual Successor/ripoff of Yamato by the same producer (The Nish), has the Anti-Proton Gun.
  • The Wave-Motion Tuning Fork-type Macross Cannon, AKA Superdimensional Converging Beam Weapon, as well as the Grand Cannon, in Super Dimension Fortress Macross and its sequels.
    • The original Macross Cannon provides the impetus of the plot: the 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 Fold Engines left the Cannon bereft of power conduits for a while, prompting the iconic transformation (which allowed the Cannon to reconnect with its power source due to the new configuration.)
      • When the recon ships were fired on, they were below the horizon from the point of view of the Macross. It actually fired through several MILES of the Earth's crust, and still managed to spear the primary target through the center of mass, and killed the other through bleed-off. And somehow the planet was still inhabitable.
    • By the time of Macross Frontier 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 also manages to pack a fully functional (if smallish) Macross Cannon into a fighter! It doesn't have as much oomph as does the battleship version, but it still has enough power to punch out the Deflector Shields of a capital ship. Also, while the original Cannon was an integral part of the Macross' design, later models modified it into a detachable gunpod. That will be hard to clean up.
    • 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 movie adaptation Macross: Do You Remember Love?, 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.
    • The Grand Cannon fired only a single shot in SDF. The novelization of the US adaptation Robotech states that this destroyed more Zentradi warships than had been lost in the entire history of the species. It makes Dolza change his mind about eradicating the humans and decide he should ally with them against his other enemies. Too bad he'd already laid waste to the Earth and slaughtered most of the population.
  • Synchro Cannons in Robotech: The Shadow Chronicles. The aliens who gave the REF the designs made them purposefully defective as part of an elaborate betrayal later.
  • The Nadesico, from Martian Successor Nadesico, had the Gravity Cannon. When that got old and stopped working against the enemy, they upgraded to the Phase Transition Cannon.
    • Arguaby a Deconstruction in the latter case. They fired it once in battle, against live targets (they had been fighting mostly Mecha-Mooks until then, they are so horrified by the ease and scale of destruction unleashed that they never fire the PT Cannon again.
    • The PT Cannon wasn't originally designed as a weapon. They salvaged a second PT engine (FTL drive) and attached it to the ship, basically to make it more powerful and faster. In desperation during a fairly hopeless fight, they decided to have the two engines focus opposing PT fields (warp fields basically) on the same area of space, literally folding space around anything in the area and crushing it out of existence, similar to what a black hole does.
    • Also from Nadesico, the Cosmos fires 7 Gravity Cannons. This is one of the few times a Wave Motion Gun also qualifies as a spammable attack.
  • Mobile Suit Gundam and its sequels, spinoffs, and Alternate Universes have a number of these. It's kind of a custom in Gundam now that every series must a huge Wave Motion Gun, sometime even two in one series. It's usually involved in the final battle or close to the end, and destroyed by the heros blowing up its weak point and causing the whole thing to go kaboom.
    • While Universal Century timeline is usually overlooked in the BFG department, especially compared to Mobile Suit Gundam Wing, it is actually better supplied with various WMGs and offers such notable pieces:
      • Ordinary warship guns in the setting are called mega particle cannons. Starting with Big Zam from the original Mobile Suit Gundam many mobile armors were equipped with upgraded versions powerful enough to blow away multiple warships in one shot. Not to be outdone entirely you later saw ships such as the Argama and Nahel Argama equipped with 'hyper mega particle cannons made to pulverize asteroid bases in one shot. This trope in its purest form, but not nearly the biggest guns in the setting.
      • For actual super weapons you have the Federation's Solar System - a scaled-up version of the mythical Archimedes Death Ray, using tens of thousands of computer-controlled mirrors to reflect sunlight at a target and possessing enough power to take a nice chunk out of the asteroid base Solomon. Zeon meanwhile has the confusingly named Solar Ray Cannon, also called a Colony Laser, which is an entire space colony converted into a laser cannon.
      • Both would be seen again under the control of the Titans in the form of Gryps II Colony Laser, as well as Solar System II was used by their prototype form during the pseudo-prequel Operation Stardust to try and stop a Colony Drop.
      • The eponymous Gundam and its deriatives from Mobile Suit Gundam ZZ has a head-mounted version of this, called Hyper Mega Beam Cannon. It is so powerful to the point where it often drains the Gundam's fusion reactor after repeated use, and at full output it can produce a beam with 20% the power of the Gryps Colony Laser.
      • The 08th MS Team OVA. After the failure of Operation British, The Principality of Zeon commissioned the construction of the Apsalus, a Mobile Armor with a beam cannon powerful enough to simply blast through the dozens of meters of earth and rock protecting the Federation's underground Jaburo base. The completed Apsalus turns out to have scalable power output, capable of putting out anything from the full-force Mountain-killer to tiny, rapid-fire pulses for punching huge but precise holes in mobile suits.
      • Finally Unicorn gives us the Beam Magnum, essentially a super-charged version of the standard beam rifle. In the Universal Century, beam rifles have e-packs, effectively energy-based magazines which contain enough energy for roughly seven or eight shots; the Beam Magnum expends all of the e-pack's energy in a single shot, producing a battleship-class particle blast. It even has a specialized magazines containing several e-packs for recharging. The same series also fields the Nahel Argama again and puts Gryps II back in service, requiring the Unicorn (and Banshee) to tank it with psychic forcefields in the finale.
    • The Mobile Suit Gundam Wing anime has a veritable collection:
      • 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 lengthy charging time and roomfuls of technicians to fire properly.
      • Finally, the weapon mounted to Battleship Libra was the series' achievement in high-velocity destruction. Along with wiping out any number of generic mobile suits, it destroyed not one, but two of the eponymous Gundams. Also, its lengthy recharge time was 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.
      • The titular Wing Gundam's signature Buster Rifle happened to be a handheld one of these. It's a large beam rifle with replaceable e-pacs capable of firing beams at various output; at maximum power it can fire a 150 meter wide beam capable of penetrating an entire space colony in one shot, though its e-pac can only allow for 3 shots of such output before reloading. Its predecessor Wing Gundam Zero wields the Twin Buster Rifle with not only twice the firepower, but can also be split into a pair of Buster Rifles. And since it is powered by a direct connection to the Wing Zero's powerful fusion reactor, the Gundam can practically fire it as many times as the pilot wants to. The Twin Buster Rifle is so powerful, the recoil from firing it 3 times in a row is one of the primary causes of the destruction of the Wing Zero Custom (though Wing Zero Custom had been badly damaged by its previous combat engagements, and was also taking heavy fire from enemy forces on the ground - both of which may have contributed).
      • Also worth mentioning is the Vayeate, designed by the Gundam scientists, which carries a large beam cannon as powerful as a Buster Rifle, but lacks the ammo restrictions because it's powered by a large energy collector strapped to its back.
      • In Endless Waltz, there is the Tallgeese III's Mega Cannon, which Zechs uses to destroy the Mariemaia Army's base at asteroid MO-III. Like the Buster Rifles above its output is also variable, with its maximum output being comparable to the combined Twin Buster Rifles, but it cannot be split into two.
    • Mobile Suit Gundam SEED and Mobile Suit 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. The Archangel-class has two of these, one in each leg. Insanely, the Izumo-class has FOUR, with two mounted to each side of the stern sections of its hull. 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 Sucking-In Lines. They're clearly based on the 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. However, the asteroid sized mirrors need to be replaced each time they're fired.
      • 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 Mobile Suit Gundam SEED Astray.
      • The GFAS-X1 "Destroy" is probably the closest a mobile suit gets in this series to packing one. In mobile armor mode, it wields two twin-barreled high-energy beam cannons on its back, while in mobile suit mode, it can launch blasts of multi-phase energy from three 1580mm cannons in its chest and one 200mm cannon in its mouth. Any one of these weapons is capable of blasting straight through an army, leaving behind nothing but molten slag. It also packs, between its two modes, twenty thermal-plasma composite cannons, ten beam cannons on its fingers, 24 missile launchers, and four 75mm automatic chainguns, for extra killing power.
    • The Satellite Cannons of Gundam X, which had the power required to fire it beamed to it from a base on the moon. The DX has two Satellite Cannons and fires them both at once. It can also fire without almost no cooldown.
      • The Satellite Cannons have the distinction of being possibly the most powerful Gundam-mounted beam weapon in the franchise. They are anti-army weapons that are so overpowered that they're almost useless for most of the series. The first time the Twin Satellite Cannon is fired, it pretty much vaporizes an island. The first Mid-Season Upgrade the Gundam X gets, in fact, involves the removal of the Satellite Cannon in exchange for weapons more suited to actually downing other Mobile Suits.
    • Mobile Suit Gundam 00's Memento Mori in the second season.
      • Every single one of Tieria's Gundams has at least one One-Hit Kill cannon on it. For Virtue and Seravee, it's the GN Bazooka; for Raphael, they're Seravee II's pincers.
      • And just like Seravee, Graham Aker's later machines, Susanowo and Brave have the Tri-Punisher, which creates a massive ball of GN particles and fires it at the target.
      • Don't forget the Gadessa's GN Mega Launcher, or the GN Particle Cannon on Big Bad's mothership with the power to take out an entire fleet.
      • And of course, Ribbons' ship, the Celestial Being, which fires a beam so massive, it takes an ENTIRE GN DRIVE IN TRANS-AM (albeit a false one) just to fire one shot. And damn is it powerful!
      • Whenever someone uses Trans-Am, whatever they fire is MASSIVELY beefed up, with no Arbitrary Weapon Range at all. Especially visible with the 00 Raiser which fires what looks to be a gigantic sustained shot but is actually a HUNDREDS OF KILOMETRES LONG BEAM SABER. The 00 Qan[T] has an even bigger version longer than the Moon's diameter.
      • Zabanya's Shield Bits can already cooperate with the Gundam's main weapon to produce Beam Spam but they can also combine into a chain of three rectangular frames that together fire a single crazy powerful shot with a maximum range in the tens of thousands of kilometres.
      • Then, of course, there's the Gadelaza, which has a beam that can blast a ship big enough for deep space exploration to bits in one shot.
    • Mobile Fighter G Gundam: Neo-America's secret weapon- the Statue of Liberty Cannon! It shoots from the torch.
    • Mobile Suit Gundam AGE has the Photon Blaster Cannon on the Diva, spruced up from the AGE Builder.
      • Which was beefed up even further with the development of the Photon Ring Ray, which in combination with the Photon Blaster can destroy colony sized targets.
      • AGE-3 has a handheld version of the Diva's Photon Blaster called the SigMaxiss Rifle, capable of killing almost any Vagan mobile suit in a single shot. It even comes with an attachment that acts as a portable Photon Ring Ray that's powerful enough to destroy capital ships.
      • The AGE-FX has the Stungle Rifle, which has even more power and range per shot than the SigMaxiss Rifle, while being about half the size. It can be attached to a larger barrel to form the Daidal Bazooka, easily capable of punching straight through capital ships.
      • Not to be left out, the Vagans have their space fortress La Gramis, which can be configured to fire a gigantic beam that can wipe out entire fleets.
    • Gundam Reconguistain G has the Conque de Venus which is a Mobile Armour which microwaves enemies. Yggdrasil has the tender beam which keeps branching off into lesser beams creating a giant "tree" of beams that destroy entire fleets.
    • Mobile Suit Gundam: Iron-Blooded Orphans has one in the form of Mobile Armor Hashmal, an ancient AI-controlled mobile armor and a relic from the Calamity War, it attacks mobile suits in proximity indiscriminately.
    • SD Gundam Force gives us the end of all examples; ultimate villain General Zeong has a beam that, at full power, can wipe out the entire universe when fired. To put it into perspective, a blast at 0.01% caused shockwaves that can be felt in another dimension.
  • The Medaforce behaves like this or a Wave-Motion Tuning Fork for most of the Medabots that can use it.
  • The Iron Ri Maajon (and a number of other Ri Maajon patterns) from Simoun. Strictly speaking, they aren't guns, but rather Wave Motion Prayers.
  • Neon Genesis Evangelion:
    • The Positron 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 that said Positron Rifle is employed against (Ramiel) produces a fusion-powered beam that goes through several buildings. Then it applies 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 really pissed off and charges a blast that melts away a fairly large mountain.
    • There's also 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.
  • RahXephon had the Vermillion equipped with an assault rifle. While it's primary function was that of a machine gun, the weapon could also fire an energy bolt that exploded with the force of a small nuke.
  • From Lyrical Nanoha:
    • The title character has three attacks that are basically a magical Wave Motion Gun, the first being "Divine Buster", the second being "Excelion Buster", and the third being the even more powerful "Starlight Breaker." The Cool Starship, the Arthra, also has the "Arc-en-ciel", which is famously used to destroy Reinforce's berserked defense program.
    • Several of Nanoha's other characters have Wave Motion Guns of their own; Fate and Hayate in particular have their respective attacks "Plasma Zanber Breaker" and "Ragnarok", 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.
    • This video shows why Quattro's face was once the page image for Oh, Crap! (and has been reinstated as the Anime and Manga page image).
    • More or less, any mage that has the title of "Ace" (Nanoha was already an Ace in the first season) or above have their own versions of the Wave Motion Gun.
  • Arika's "Bolt From The Blue" in My-Otome. Unfortunately, her equal and opposite number Nina has a similarly-powerful attack as well in both her robes. Natsuki also has her Howling Silverwolf attack, debuting near the end of the series in a massive Beam-O-War with Nagi's siege cannon.
  • Similarly, in My-HiME, Mai's CHILD Kagutsuchi can take out an entire aerial fleet.
  • The super weapon in The Legend of Black Heaven falls under this trope as well as being rather hard to activate.
  • In The Red Ranger Becomes an Adventurer in Another World, Tougo's Victory Kizuna Buster unleashes a huge laser that causes a massive explosion on impact. But it only works if all of its users are in sync and not arguing with one another, otherwise the beam will split in half and completely miss its target.
  • The rifles carried by the gigantic Nobuseri leaders almost qualify, but more properly, the main guns of the Imperial Capital Samurai 7.
  • Space Runaway Ideon has more than one.
    • The Ideon Gun is one of the most powerful examples, powerful enough to devastate a good portion of a star system. It's particularly fun to use in the Super Robot Wars 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.
    • In the movie Be Invoked, the Buff Clan have their own WMG in the form of a colossal space station that concentrates the energy of a supernova into a beam. It finally destroyed Ideon, at the cost of getting rid of everyone.
  • In El-Hazard: The Magnificent World, both the OVA and TV incarnations of Ifurita wield a "Power Key Staff" whose full power gun blast is basically a "nuclear bomb ray." She destroys an entire city with it in in the anime, and a mountain in the manga. It takes some time to recharge, but not much. How she wields it is probably the crucial difference between the two continuities. 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 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. Or so we've been told... The GBE is considered a Class 9 weapon of mass destruction in Blame and is VERY rare to to come across. To give you an idea, at lowest setting, it can shoot a beam 70 km long. Anything in this path is obliterated. At maximum firepower...um...you'd have to see it for yourself.
    • And the recoil is so powerful that it has a pretty good chance of utterly obliterating the wielder's arm and flinging him like a ragdoll on anything but the lowest setting.
    • Pretty much every non-mook gun in a Tsutomu Nihei series. The various artificial humans in Biomega all have these; the male lead has two, just in case.
  • 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 Transforming Mecha). He's got three, ranging from "standard finishing attack" through "frag the whole area" to "Combined Energy Attack as strong as a small nuke."
  • In Fate/stay night and Fate/Zero:
    • Odd as it might seem, Excalibur is essentially a Wave Motion Sword. When it is charged, it can fire off waves of destructive light. Using it one-handed reduces it to mere concrete-rending level; using with both hands can raze cities.
      • Actually makes sense from a mythological standpoint—Excalibur's legend was derived largely from the sword Caladbolg in Irish Celtic Mythology, a two-handed sword which can emit destructive energy beams.
    • Ea, the Sword of Rupture, was specifically designed to resemble a subterranean tunnel drill, and once charged up—via, naturally, spinning—it can rip apart space-time. For a while, it was the only weapon in Nasuverse ever classified as "Anti-World." As of FGO's release, it's now matched by Rhongomyniad.
  • Bizarrely enough, One Piece has these, thanks to its Ocean Punk theme allowing for even a pirate ship to be armed with one of these things:
    • The Thousand Sunny, the Straw Hats' second ship, has the "Gaon Cannon" technique, which concentrates three barrels' worth of cola into a massive, badass and powerful energy beam. Luffy was brought to Tears of Joy the first time he saw that attack.
    • Marine Admiral Kizaru can shoot massive beams of light from his hands and feet thanks to his Devil Fruit, the Glint-Glint Fruit.
    • The Pacifistas, robot weapons built in the likeliness of Warlord Bartholomew Kuma, have laser beams as their main weapons in lieu of the real deal's Paw-Paw Fruit power. These beams were implemented thanks to Dr. Vegapunk's research on the Glint-Glint Fruit.
    • After the Time Skip, Franky upgraded his body with some of Vegapunk's technology, allowing him to use his own freakin' laser beam, the Franky Radical Beam. His Robot Me, the General Franky, has one of its own for good measure.
    • The oldest example in the series dates back to the very first movie; non-canon though it is, its villain El Drago had consumed the Scream-Scream Fruit, which gave him the ability to project beams of energy from his mouth using his vocal chords.
    • Eustass Kid is able to summon a massive cannon with his Devil Fruit. Referred to as "Damned Punk", it was key to getting Big Mom off Onigashima.
  • In My Hero Academia, Yuga Aoyama's Quirk gives him a small-scale version of the trope, allowing him to shoot lasers from his navel. His customized costume allows him to shoot from other parts of his body as well.
  • The Big O has the Final Stage attack, which, in something of a twist, misses.
  • Hadron cannons in Code Geass, 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.
    • Don't forget the Shen-Hu's Baryon Cannon.
  • 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 Dragons or the Big Bad. Of particular note is the Berserk Fury, which has three charged particle cannons.
  • In Nausicaä of the Valley of the Wind, the God Warrior's primary weapon is essentially a Wave Motion Gun. 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.
  • In Castle in the Sky, Sodom and Gomorrah were but two places destroyed by it, according to Muska.
  • Getter Robo:
    • In the original, the Eagle Unit (one of the three machines that forms the eponymous Combining Mecha) was a small jet that could fire puny laser beams. By Shin Getter Robo it had upgraded 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 it actually happens. In fact, it's implied that this is how the universe was created. By a Humongous Mecha-slash-Cool Ship shooting beams of evolutionary energy into space.
    • Shin Dragon in Getter Robo Armageddon has one inside the dragon's mouth powerful enough to blow up one of Jupiter's moons!
  • 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 Applied Phlebotinum in his revolver. Talk about miniaturization...
  • In the Naruto manga series:
    • Chakra cannons were basically this, charged up by the chakra of groups of ninjas. One of them was powerful enough to potentially destroy the moon.
  • A lampshade is hung on this in Excel♡Saga, where Excel calls the weapon on the Puchuu starship a Wave Motion Gun, in the episode that parodies space operas.
  • Parodied in The Girl Who Leapt Through Space. 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. The show being what it is, though...
  • Tengen Toppa Gurren Lagann 's Infinity Big Bang Storm is a borderline version; how many times do you see someone being attacked with the Everlasting Hellfire of The Universe's Creation? What's more important about this one is the fact that the main characters not only block it, but through sheer awesome absorb it and turn its power against its wielder.
  • In Negima! Magister Negi Magi:
    • One of Asuna's flashbacks reveals during magical war, among (slightly smaller than the above mentioned demon) god soldiers, ancient war dragons, and Magic Knights, battle whale ships that wielded one of these called the divine/spirit cannon. Presumably the strongest artillery weapon in the Magic World, Asuna's Magic Cancel completely eliminated it.
    • And then there's Chachamaru's Artifact, a freaking Kill Sat she uses to utterly obliterate the Eldritch Abomination that a few moments earlier had cut in half a Gold Dragon like butter.
  • 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. It's a 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 detaches from the user, leaving them with just their normal Megasmasher and an assload of fatigue.
  • The Five Star Stories has the Buster Launchers, enormous cannons the bigger of which (starting from the 2 meter caliber) are fully capable of obliterating planets. The common Prowler Space Fighter usually mount at least two of these, and as such is considered overpowered, and was replaced by the Mortar Headds planetside. Later, though, a couple of MHs were armed with busters, making them the most heavily armed mechas in the universe.
  • Mazinger Z's 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.
    • While the Photon Beam is usually Mazinger Z's weakest attack, the one from Shin Mazinger becomes this after being throttled to maximum power.
  • The flagship of the Iron Tribe's fleet is equipped with one of these in Heroic Age. 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, the Argonaut has the capability to shift into an enormous gun form, firing a Wave Motion Gun aptly named the "Star Blaster".
  • Something that has remained fairly constant throughout the various incarnations of Astro Boy 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:
    • Coyote Starrk has pistols that fires Cero in his released form. Think of Gravitational Beam Emitter, times two.
    • In the first movie has something called the Kido Cannon, which destroyed an entire pocket dimension.
  • Eureka Seven: The ultimate attack of the spec-III Nirvash typeZero.
  • Fairy Tail:
    • The Magical Convergent Cannon: Jupiter. Extra points... to Erza, actually, because she just tanked it in the face before going off to kick even more ass.
  • In Angel Links, the Links Cannon ("shooooo-toh!") settled pretty much every fight. Some fans, expecting more frenetic space combat scenes in the style of Outlaw Star, were a bit annoyed by this.
  • The combined power of four Weapons and one meister, Kirikou (with a little help from Kim), creates one of these in Soul Eater which destroys Medusa's Black Clown. Lightning, fire, and two pistols.
  • Gunbuster's Buster Beam. It destroys fleets with one shot.
    • And the sequel, DieBuster, slices a planet in half with the weapon.
  • From Slayers: Dragon Slave!
  • In Legend of the Galactic Heroes the fortress Iserlohn is equipped with the weapon "Thor's Hammer" that is more than capable of destroying entire fleets in a single blast.
  • Battle Angel Alita: Last Order, features a 500 ton Jovian combat cyborg among other things armed with a miniature wormhole connection to the inner parts of the planet Jupiter. You may try to imagine the scale of destruction caused by the pressurized plasma-or-whatever-may-be-the-next-state-of-matter-after-plasma in there being released in a focused beam, but it's probably nowhere close.
  • Tekkaman and its reimagining Tekkaman Blade both have the Voltekka as ultimate attacks.
  • Super Atragon: The enemies' giant black cylinders fire lasers that can cut a modern destroyer in half in seconds.
  • IRIA: Zeiram the Animation:
    • The burabudin cannon is basically a hand-held WMG. While capable of firing controlled and precise blasts, it can also fire massive continuous beams that can sweep whole armies off the map.
    • The maduradin cannons are similar to the burabudin, but in vehicle form.
  • Starship Operators, the Amaterasu's plasma cannon.
  • In Vividred Operation, Vivid Yellow's Vivid Collider is a human portable particle accelerator / wave motion cannon capable of vaporizing the show's monster of the week pretty much instantly.
  • Arpeggio of Blue Steel Super Graviton Cannons. The weakest variants, wielded by Fleet of Fog heavy cruisers, can easily vaporise anything in line of sight, likely up to and beyond low Earth orbit considering their weaker laser weapons can do this. The most powerful are the battleship-class cannons that take up the entire length of a ship and do a significantly scaled-up impression of Moses parting the Red Sea while they charge up; they warp spacetime in their line of fire.
  • Transformers: Armada has the Hydra Cannon, a Doomsday Device formed by the combination of the three MacGuffin weapons.
  • In Unlimited Fafnir, Yuu can summon a variety of these thanks to his contract with Yggdrasil, which can be used to kill dragons. Unfortunately it's a Dangerous Forbidden Technique, as summoning these weapons costs him some of his memories.
  • Made in Abyss—Reg has one of these implanted in each of his robotic hands; it's made from unidentified precursor technology, and dubbed the "Incinerator" by Riko. Most of the time he focuses it into a relatively small beam, but the first time he fires it after losing his memories, he goes overboard and vaporizes a cluster of stone pillars the size of skyscrapers; whether even that was the limit of its power is unknown. This has a major Achilles' Heel in that he passes out for two hours shortly after firing it.
  • Artralia in The Dark Queen and I Strike Back is a massive stationary railgun that can hit anywhere on the continent with enough power to reshape the landscape. It's also powered by the lives of inhumans; this fact discourage the inhumans from using it when they capture it.
  • Puella Magi Madoka Magica The Movie: Rebellion: Mami is known for making firearms with her magic, but we get to see her Tiro Finale which she conjured on a dual rail line, and it's powerful enough to annihilate several city blocks and kaiju sized familiars.
  • Rebuild World:
    • When Akira upgrades to his fifth model of Powered Armor, the KIRYO CA 31R, it comes with a back mounted AF anti-material cannon particle weapon to deal with Mini-Mecha or Kaiju. He can also put it onto the remote weapon mounts of his Cool Bike to allow his Virtual Sidekick Alpha to fire it. It has a dispersed blast mode for use against smaller enemies gathered in The Swarm, but that’s not cost-efficient.
    • When Akira gets hired for an Escort Mission of a Big Badass Rig convoy, the vehicles are equipped with some of these to handle the bigger monsters common to the east of where Akira lives.
    • When a giant cloaked Flying Saucer attacks said convoy, it sends smaller black Attack Drone saucers down while providing fire support with its own beam weapon. The transport Akira is on nearly gets obliterated by it, but since the saucers are targeting a different group of monsters, Akira destroys the last one of those just in time to make it fire its huge blast at a different monster further away.
    • Akira ends up fighting a giant bee shaped Mechanical Monster with one of these in place of a stinger, designed for air-control by the Old World Neglectful Precursors.
    • Carol eventually brings a laser cannon equivalent to Akira’s AF cannon she uses for Combination Attack strikes with Akira and Alpha. After spending part of The Siege of Akira and Sheryl’s Home Base jumping between rooftops to take out enemy armor, Carol ends up losing the cannon in the chaos, where it’s eaten and assimilated by a monster.
    • Akira eventually replaces his AF cannon with a TGP Laser Cannon.
  • GaoGaiGar: The Solitary Waves used by the synchronized Mic Force demonstrate immense destructive force.
  • Blame! in the early sequences of the movie, Killy saves the electro fishers with his Gravity Beam Emitter which fired an extremely long red beam that instantly put a large perfectly cut hole in everything it touches.

    Card Games 
  • Yu-Gi-Oh! has a couple of these, such as the much-loved/loathed/feared/dreaded Wave Motion Cannon, which charges up as the turns go by and can be removed from the field to blast the enemy for 1,000 damage per turn it has charged; Satellite 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 Seto Kaiba's signature monsters — XYZ Dragon Cannon uses this whenever he discards, etc.
  • ZG has a special class of weapons intentionally referencing this trope. It is differentiated from ranged weapons by laying down a pattern of cards that hits everyone in the designated "zone". It is called a Zone Weapon.
  • Magic: The Gathering's Kaladesh set has the Aetherflux Reservoir, a massive artifact that resembles a cross between a water tower and a snowglobe, and has been nicknamed the Death Star for its ability to blast any target for a full 50 damage in one shot. For context, Emrakul, a cosmic horror that is basically the in-universe equivalent to Cthulhu, can take 15 total damage before dying. Yes, this thing can one-shot an ancient eldritch god three times over. Of course, firing this monster requires you to expend an equivalent amount of life, but it also lets you charge it up by granting you exponentially increasing amounts of life for each spell you cast on the same turn.

    Comic Books 
  • The Dark Empire series of Star Wars comics gave us the Eclipse-class Star Destroyer, which has a bow-mounted, downsized version of the Death Star's superlaser. ("Downsized" means "Won't actually blow the planet apart, but will still kill everything living on it.")
  • All Fall Down has the Reducto-Beam, a colossal shrink ray on the moon that runs on Living Batteries.
  • Albedo: Erma Felna EDF has the Matter Conversion Cannon, a weapon so powerful, it can, in theory, dwarf in power the Space Battleship Yamato 2199 version of the Trope Namer, since it can destroy a whole galaxy in a single shot by eating matter from near sources and weaponize it against a single target. Eating the matter from a star could, in theory, destroy not only the star itself but also everything near it due of a supernova.
  • In the Pre-Crisis days of DC's Legion of Super-Heroes, one of their many overpowered weapons was known as the Concentrator, which would supposedly channel all of the energy in the universe at once into a single, concentrated death ray. When it was fired, all the stars temporarily went out, cars and other machines ground to a halt, etc. (Although for some reason people and other living beings continued to be able to move and act just fine).

    Fan Works 
  • In Power Girl story A Force of Four, the heroes use the Purple Ray, a giant energy canon, to destroy Mars once and for all.
  • The first chapter of Bait and Switch has a brief mention that the Kira Nerys, an obsolete Bajoran patrol frigate that the protagonist served on as a noncom, featured a spinal phaser cannon that took long enough for the bridge to bring to bear against an Orion Syndicate pirate ship that the Orions shot up the ship pretty bad and were able to beam several boarding parties aboard. Once they got it into position, though, it blew the other ship away in one shot.
  • Doing It Right This Time: When Shinji talks about Ramiel and his humongous particle beam, he describes that Robeast as "the Angel of Wave Motion Gun".
  • HERZ: In order to try to gain the upper hand against HERZ's Evangelions several countries build downright massive proton cannons, some of them mounted on weaponized satellites, which shot huge laser blasts. They were effectively used against the MP-Evas.
  • In Monsters In Paradise, we get Water Sign: Newton's Wave Cannon, the first step in Patchouli's plan to develop a Last Word spellcard for herself. Its appearance isn't outright revealed in-story, although a bed-ridden Remilia complains that Patchouli pretty much ripped off the Master Spark when creating it.
  • Once More with Feeling: In episode 7 the cast fights Ramiel -an Eldritch Abomination armed with a huge laser blast-, building a gigantic cannon shot a massive particle ray.
  • In Origins, a Mass Effect/Star Wars/Borderlands/Halo Massive Multiplayer Crossover, the Star Dreadnaught Ultimatum mounts one of these in the form of a superlaser. So does Cronos Station—but that one doesn't work. Just because you know how to build a superlaser doesn't mean you can do it right.
  • In Thousand Shinji, The UDPIDTEPW, or Unidirectional Positron Initiated Deuterium-Tritium Enhanced Plasma Weapon is a very big thermonuclear weapon. Unofficially it's actually called the Wave Motion Gun.
    “It’s called the Wave Motion Gun by the build team, isn’t it?” Shinji suddenly asks.
  • A Crown of Stars: The positron cannon that protected Postdam's missile launch complex was a massive laser beam cannon. It was capable of blasting an eighty-meter-tall Transforming Mecha.
  • Two of these show up in Fantasy of Utter Ridiculousness. The first is the Idiot Gun, courtesy of Megas, and it lives up to its name with no small thanks to Sagume Kishin. The second is Yuuka's Double Spark; it was already a powerful attack in its own right, but after she was scaled up to Megas's size, the resulting beam becomes large enough to be seen from space.
  • The New Adventures of Invader Zim has the Lost Superweapon known as Project Domination, which at minimum power unleashes beams of energy the size of airplanes, and at maximum power is speculated to be able to punch holes into the Earth's surface the size of Lithuania.
  • In Blessed with a Hero's Heart, Megumin creates a spell she names "Big Bang" with Izuku's knowledge about nuclear physics, which is much stronger than Explosion and consumes less mana. She later modifies it by leaving a hole in the containment field to force the energy out through it, creating a death ray strong enough to blast through the Destroyer's barrier and split its head, calling it "Eraser Blast".

    Films — Animated 

    Films — Live-Action 
  • Star Wars:
    • A New Hope, Rogue One and Return of the Jedi all feature the Death Star (in the case of Return, a second one). The Death Star is a space station roughly the size of a small moon, capable of traveling anywhere in the galaxy, featuring a superlaser that blows up planets (or in the second Death Star's case, blows up capital ships and planets). Rogue One and its supplementary materials particularly play off the nuclear weapon metaphor: it was first conceived as part of an arms race during a war, and on the lowest "only destroy a city" level, it leaves a giant mushroom cloud. The first Death Star is famously weak in a tiny thermal exhaust port at the end of a long trench.
    • The Force Awakens tops the Death Star with the Starkiller. Its Superlaser is embedded inside an ice planet, Thousands of times the size of the Death Star. It drains the mass of a nearby star and converts it into multiple beams that can destroy an entire star system on the other side of the galaxy. The Death Star showing up in your system would be bad news, but with the Starkiller, you wouldn't even get that warning.
    • In The Last Jedi the First Order brings out a battering ram cannon, which is a massive cannon bigger than an AT-AT that is built on miniaturized Death Star superlaser tech.
    • And then The Rise of Skywalker tops all that with a fleet of Star Destroyers that are all armed with planet-busting superlasers.
  • Godzilla and related films:
    • The reoccurring Maser Cannon weapons, which fire a beam of electro-atomic energy, and are actually one of the few manmade weapons that consistently hurt kaiju.
    • Kiryu also had the 'Absolute Zero Cannon', which was capable of equal destruction.
    • In Godzilla vs. Megaguirus, the humans decide to try and use one called the Dimension Tide on Godzilla, which literally fires a Black Hole. Side effects include ripping a hole in the fabric of space and time and creating the movie's main monster.
    • The Mirror of Amaterasu from Yamato Takeru is capable of launching a beam of divine sunlight powerful enough to destroy Tsukuyomi's physical form. After it helps Yamato Takeru transform into the giant warrior Utsuno Ikusagami it turns into an even more powerful weapon, and delivers the final blow to the Yamata no Orochi.
  • 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.
  • The "Hammer", the primary weapon equipped to the city-destroyers in Independence Day certainly qualify. Fired down from the saucer, they can easily demolish an entire city.
  • The Bifrost, properly mishandled, is almost one of these in Thor. And it has the greatest range of anything on this list, striking through wormholes, though it takes longer to get to work.
  • Half of the super weapon used by the bad guys in Star Trek (2009). It's actually an orbital mining laser used by the Romulans to get Red Matter into the core of a planet.
  • Star Wreck: In the Pirkinning has got the Excavator, the most powerful battleship from the Babel-13 universe. It is equipped with an extremely powerful and destructive main Ray Gun which draws a lot of energy from the ship after it has been fired: The Excavator remains devoid of electricity for one minute. Everything has to shut down, including the heating.
  • In War of the Worlds (2005), the Tripods have these, on top of their heat rays. While the heat rays function primarily as antipersonnel weapons, turning a victim (quite explosively) into a cloud of ash without even burning through their clothing, the larger energy weapons used by the same war machines are capable of turning an entire block to rubble with no effort, or shredding the Bayonne Bridge like it's made of cheap cloth ribbons.

    Literature 
  • The Dr. Device/Little Doctor in Ender's Game, so named because it was developed as the Molecular Disruptor 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. It allows Ender to rewrite the book on military strategy by attacking the enemy formation where its ships are most heavily concentrated. Ender asks if the device could be used on a planet; the response is a horrified shudder. And then he tries it on the Bugger homeworld, annihilating it in a single shot.
    • In the film, the weapon has a recharge rate of several minutes, and only a single ship is equipped with it. Also, despite annihilating a large Formic fleet, it only turns their homeworld into a volcanic hellhole instead of atomizing it.
    • Thousands of years later, the weapon has been turned into a torpedo. Why? Because it has a relatively short range on its own, and trying to use it against anything big (like a planet) will likely result in the firing ship being destroyed as well. A torpedo essentially consists of an engine, a guidance system, and the Little Doctor. The Little Doctor is designed to fire at the inner housing of the torpedo, effectively turning the torpedo's own mass into the initial blast, meaning the torpedo doesn't actually have to impact its target, just get close enough for the destructive field to reach the target. It's also designed to be easily disarmed to avoid any accidents. Another advantage of using a torpedo is that the firing ship doesn't actually have to decelerate from near-light speeds to deploy it, thus sparing the crew from spending too much time decelerating and accelerating (let's ignore the Park Shift for this one).
    • The weapon's development is shown in the prequel Formic Wars series. Originally designed as an efficient means of asteroid mining (vaporize the rock, vacuum up the molecules), the "gravity laser" (or "glaser") has proven to be nearly as dangerous to the mining ship as to the asteroid due to the size of the field. During the First War, they are used both as weapons and in so-called "shatterboxes", which are two boxes, each holding a glaser, pointing at one another and connected by a rope. They're launched bola-style at the enemy and use the opposing gravity forces to limit the size of the field to the target ship.
  • The Lensman Arms Race is a trope for a reason. E. E. "Doc" Smith's novel Second Stage Lensmen features the sunbeam, a weapon which concentrates into a single beam the entire radiant energy output of a star. (And the enemy had plans to extend the principle to novae or supernovae.) Starkiller Base from the Star Wars franchise operates on much the same principle for its energy, but the Sunbeam uses various dispersed deflectors and beam-steering grids floating in space and has a much more limited range (its developers admit they can't hold the beam together from the sun of the enemy system to its eighth planet).
    • The "primaries", so-called because they're the primary weapons of the ships. When some new (readily portable) tech comes along, those become the primaries and the former primaries become secondaries (or tertiary, and as far down the list as you care to go before they're no longer worth the mass/space to take along). The culmination of this (which happens even before they start throwing planets around) is the one-shot primaries, which are the strongest beam weapons available deliberately overloaded so that they emit one unbelievably strong pulse before exploding. This was initially developed by some Boskonian genius who realized that trading one gun and its crew for one enemy ship and its crew was actually a pretty good exchange if you weren't a member of the gun crew involved. The Patrol, once they figured out what was going on, made it non-lethal (to the attacker) by shielding the hell out of the inside of the turret and operating them by remote control.
    • The ultimate ultimate weapon of the Lensman series was a psychic Wave Motion Gun, since the Eddorians could not be killed by any physical force, however applied. It consisted of the gestalt mind of the Children of the Lens (the UNIT), backed by the integrated minds of all of Arisia and powered by the maximum-effort mental output of every Lensman of the Galactic Patrol.
  • In one of John W. Campbell's Arcot, Wade and Morley novels, the eponymous 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.
  • 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.
  • Stanisław Lem's The Invincible, while having a crew that was at best Mildly Military, 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".
  • Ed Hamilton's The Star Kings featured a Disruptor — 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.
  • In Iain M. Banks's Against a Dark Background the Lazy Guns were ancient weapons created by a long dead race that destroyed their target with a suitable dark humoured effect. A person might suffer a heavy anchor to appear above them, or a shark to materialize and bite their head off. A city will be unexpectedly hit by a comet or have a volcano erupt in its main square. The implication is it plucks something from elsewhere in the multiverse and pops it into its own universe where it dispatches the target - with a sense of humour.
  • In the universe of the Culture, there are several versions of this, from CREWs (Coherent Radiation Emitting Weapons), basically lasers, to "Line Guns" which go largely undescribed but appear to generate transient 1-dimensional gravity singularities — effectively a black hole beam.
  • In Sergey Snegov's The Men Like Gods, people use a device called "Tanev's annihilator", which can convert spacetime to matter and vice versa, as an engine. While not initially being all that warlike, they find the side effects of their favorite space drive quite useful later, when rather unfriendly aliens appear. The heroes go on to befriending the crap out of said aliens, in the best Nanoha-style, and then teaming up with them when the next bunch of the enemies arrived. THREE TIMES. Also, the Ramirs (ancient super-advanced civilization, which lives in the galactic core) utilise Roton Beam, which can be switched from "burn the planet" to "blow up the star" mode and has an interstellar range.
  • The Forges of Mars novel Priests of Mars brings us an especially remarkable example — in a setting where you already have weapons capable of destroying suns — during the climactic space battle of the book in the form of the Speranza's secret main gun, a chrono-weapon from the Dark Age of Technology that none the crew of the ship were even aware of which is capable of generating a black hole that disrupts space and time without the need of Warp sorcery in an astronomic area of effect.
  • Larry Niven's Known Space stories include 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 Man-Kzin Wars, the Terran system is defended from invaders by the Mercury Laser; it's 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, lasers powerful enough to drive solar sails are just as grand.
    • In "The Warriors", a human colony ship uses 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 war and weapons haven't been seen on Earth for hundreds of years now. The captain has a 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. He explains that since he was trying to get away from the Kzin ship, he naturally pointed the drive in exactly the opposite direction: directly toward the Kzin ship. His crew are still pretty squicked by it, because there's considerable evidence he knew exactly what he was doing.
    • There are a lot of 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 Word of God that all these technologies were created with a dual-purpose in mind by the paranoids of ARM.
    • The story "Madness Has Its Place" has as protagonists a former ARM agent and some allies who go to some lengths to arrange that one of them will be at the Mercury Laser station at all times, just in case it needs to be pointed at ... something. It's left somewhat ambiguous whether they actually got away with the plan or were allowed to get away with it, and whether the very existence of the Mercury Laser in the first place is a lucky happenstance or a matter of foresight on the part of like-minded people years ago.
    • "The Soft Weapon" features a 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.
    • The Wunderland Treatymaker, based on an alien 'excavation tool', creates two areas, one that suppresses the negative charge of electrons, and one that suppresses the positive charge of protons. The humans made an orbital version. After it was used, they renamed the planet Canyon after its defining feature.
    • The Ringworld itself is defended by a laser that is generated from artificially produced sunspots. It shoots a laser beam larger than Earth's moon. The kzin on the team comments, "With such a weapon I could boil the Earth to vapor."
  • Footfall (by Niven and Jerry Pournelle) has some real-world realizable ones: The climactic battle involves the Orion-drive powered Archangel Michael (see Real Life section below for a description of what the fuel for one of these suckers is like) that also drops 'spurt bombs' into the drive blasts to power them up. They fire beams of coherent x-rays. The aliens use landing vessels the size of an aircraft carrier, which are launched back up to orbit on launch lasers. That means they've got ground based lasers with hundreds of times the sustained energy output of the largest chemically powered rockets.
  • 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 multiple stars 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.
  • In Alan Dean Foster's Humanx Commonwealth series:
    • The various Precursor races 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 Grand Finale, Flinx Transcendent. Flinx finds a roaming Tar-Aiym 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 that isn't enough, 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 Revelation Space Series. Some can blast big holes in a planet's crust. Others can destroy stars (or so we're told).
    • The Hypometric weapons are rather less flamboyant, but in many ways more alarming. They simply cause everything in a specific volume of space to just... disappear. No debris, no radiation, no explosion. The effect propagates at lightspeed, and appears to be impossible to defend against (though perhaps the Inhibitors might have some tricks in that regard).
    • The Inhibitors have a range of techniques and designs for dealing with troublesome interstellar species. They used one such trick to generate a lethal solar flare and destroy the civilisation on Resurgam. When the inhibitors noticed a new civilisation there, they decided to construct a "Star Singer": a device built around its star that triggers a gigantic and continuous solar flare, or in other words an interplanetary flamethrower, to reduce the surface of the inner worlds around the star to slag one by one. This substantially reduces the star's mass, turning it into a red dwarf.
  • 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".
  • Stephen Donaldson's The Gap Cycle 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 Death from Above 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 (successfully) fired. A sort of a reverse Chekhov's Gun. Despite its supposed usefulness, the good guys do not have one — even at the space police headquarters at Earth.
  • Andrey Livandny's The History of the Galaxy series has the LIGHT annihilation system, developed by the Free Colonies to combat the technological superiority of the Terran Alliance. How it works is not explained, but it acts as a weapon of mass destruction on a planetary scale. As an example, the first time it was used in battle it obliterated a moon and two armadas. Needless to say, it was later more used as a deterrent than a weapon. The reason was stated that the firepower of the weapon could not be adjusted. It simply turned to energy anything in its path with destructive results. Apparently, anything within a light minute of the target is simply vaporized. One of the novels has a Terran Alliance admiral plotting to capture an intact LIGHT system, even though his Number Two keeps pointing out the ridiculousness of the action. The Alliance could build one if they wanted to, they've done enough scans of the colonial weapon to be able to reproduce it, it's just that it's not worth the expenditure in time and resources due to its uselessness as a weapon of war. The admiral in question actually wants the weapon as part of his plan to usurp the leadership of the Alliance from the aging Admiral Nagumo. It's to be his ultimate deterrent against his political opponents trying anything. The colonials manage to self-destruct the system, though.
  • In Mikhail Akhmanov's Arrivals from the Dark series has many alien races using Annihilators (i.e. antimatter cannons), the only defense to which are Deflector Shields. The first novel, Invasion, shows humans get their asses handed to them by an alien starship armed with these, while humans are still using missiles, magnetically-launched icicle spreads, and low-power plasma weapons. The subsequent novels shift the Annihilators into the more common variety of weapons with missiles and magnetic weapons relegated to ground-based use (no one in their right mind would use antimatter weapons in an atmosphere). Plasma weapons remain as secondary weapons for capital ships and primary weapons for fighters.
    • These also can be used to turn a planet into a smoldering hellhole in about an hour, although this is rarely done, as habitable worlds are valuable.
  • In the Dale Brown novel Flight Of The Old Dog, the Soviets use a laser system rated at hundreds of megawatts for anti-ballistic missile, anti-satellite and basically anti-whatever purposes. The eponymous Airstrike Impossible is carried out to destroy it.
  • Timothy Zahn's The Conquerors Trilogy has the human's CIRCE weapon, which is capable of completely obliterating any fleet it goes up against. Subverted because CIRCE doesn't actually exist. The first and only battle where it was 'used' was actually won by an insane fluke of luck. The politicians of the allied nations who owned the fleet came up with a fake ultimate weapon as an explanation and used it as a threat to secure their own political power.
  • In the Star Trek Expanded Universe novel Vendetta, the USS Repulse uses a deflector dish weapon (much like the ones used in Star Trek: The Next Generation — see below) to blow a Borg ship to bits. To be fair, though, that cube had already been heavily damaged in a battle with a spaceborne version of The Juggernaut.
    • Additionally, the Alternate Universe Star Trek: Voyager story Places of Exile seems to reference the trope itself; shortly after Species 8472 blew up a Borg planet (like in "Scorpion"):
    This time they were not so lucky. "The first bioship is on a pursuit course," Tuvok reported.
    "Just one? That's a relief," said Paris. "I'd hate to have to take on the other nine and that wave-motion gun of theirs." Janeway assumed the weapon description was another of Tom's obscure twentieth-century cultural allusions.
  • Hellbores are fusion cannons rated in megatons per second and standard armament on Bolos; the larger Bolos mount several. They were originally developed from weaponry intended for use as the primary armament of space battleships.
    • Eventually Hellbores were made part of a Bolo's secondary weapons to the point where a Bolo could have over a dozen Hellbores, granted the secondary Hellbores were smaller in size.
    • Some Bolos were equipped with a Hellbore variant called a Hellrail. These were normally larger than the Bolo's main armament, but could not be depresed to engage ground targets. They were intended explicitly to engage spacecraft. As a Hellbore is capable of pin-point accuracy at interplanetary range, this is a serious threat to any enemy operations in an entire star system.
  • Besides the Death Stars mentioned above, the Star Wars Expanded Universe has several other superlaser platforms, mostly large ships. They're not planet killers, but are instead mostly used against other large ships. Centerpoint Station also has a pretty impressive gun.
    • Special mention must go to the Hutt superweapon, the Darksaber, which was quite literally a Death Star stripped down to the bare essentials, an engine, a powercore, and a superlaser, shaped like a lightsaber. Except it didn't work because the Hutts cheaped out on the construction. Worst. Big Bad. Ever.
  • In Troy Rising, the SAPL is one. The acronym stands for Solar Array Pumped Laser (the protagonist had a lot of Fun with Acronyms, "SAPL" was intended to also stand for "Serious-Ass Powerful Laser" and was made of various "Very Dangerous Arrays," "Very Scary Arrays," and "Big Damn Arrays" that officially stood for something else), despite it not actually being a laser; it consists of a whole friggin' lot of mirrors in solar orbit, the most critical of which have Lots of High Tech in order to reflect up to petawatts of sunlight without immediately blowing up. The first time they're used, against an alien cruiser that basically took over the Earth in the first chapter, the beam is aimed at a patch of shield that was collapsed by a breacher round. It misses, hits the undamaged front shields, and punches straight through the entire ship.
    • Then they upped output by few magnitudes. Best part? It was used primarily for orbital mining.
  • The Mortal Engines Quartet uses them as a plot device with MEDUSA (salvaged from old tech) and then ODIN, the Kill Sat.
  • Honor Harrington:
    • Zigzagged in the first novel. Honor is horrified that her ship is stripped of most of its regular armament to make room for one of these. Why? Because it only works at short range, and her opponents can easily blast her light cruiser to smithereens long before she gets there. Then Double Subverted in that the novel conspires to put Honor and her opponent in exactly the situation where she can legitimately use the weapon against him. Then turned back into a subversion with the brass accepting the overall uselessness of the weapon, and electing to not mount it on any more ships.
    • Defied at some point prior to In Enemy Hands. A Noodle Incident mentioned by Admiral White Haven had saner heads veto an attempt by Admiral Hemphillnote  to fit ships of the wall with enormous spinal energy weapons. The obvious problems being A) at this point in the series it's impossible to generate a Deflector Shield to cover the front of the ship, so you're leaving yourself open when you attempt to use it, and B) it would still probably be drastically outranged by missile spam.
  • The protagonist of Charles Stross's Accelerando uses a "blaster" at one point. Apparently it consists of a wormhole system, one end of which orbits within the photosphere of a star. Pulling the trigger briefly opens the portal, and (rather surprisingly) doesn't destroy everything in the vicinity. Some of the highest levels of overkill in a handweapon, given that the same design could conceivably slag an entire world.
  • The Hostile Takeover (Swann) series has the Linac, a kilometer and a half long railgun that accelerates projectiles to half the speed of light. It is unique in the universe, not because no one else has the technology to build one, but because no planetary government would allow such a thing in orbit around their planet. Bakunin has no government, so when Proudhon Spaceport Corporation built it, no one bothered to stop them.
  • Perry Rhodan tends to not make much use of this trope in part because after the introduction of the transform cannon fairly early on at the latest the setting's mass-produced stock weapons are already incredibly destructive. When your battleships can already teleport dozens of 1,000-gigaton nukes per salvo each wherever they want them, subject only to the limits of their targeting systems, and keep that bombardment going for fairly extended periods, there's not much call for even bigger guns. (Some rare examples have come up, such as the one-of-a-kind Selphyr-Fataro device installed on the BASIS which was in principle capable of sending matter in a large sector of space on a one-way trip into hyperspace; however, that one in particular, while used as a plot device a couple of times, never actually fired a shot in anger at an enemy.)
  • In The Night Land and Awake in the Night Land the human Citadel City can release a powerful blast of energy on order to obliterate a horde of monsters trying to invade the city. However this is only used in extreme circumstances, since it consumes too much energy and leaves the city without power for days.
  • Sure people know the planet-busting weapons of the Star Wars movies and perhaps the now non-canon books or comics. But long before the Death Star, the galaxy had the mighty turbo-laser. One of the DK info books mentions how powerful some of the Star Wars weapons were. When put to max power, the laser cannon on an X-Wing becomes a kiloton class weapon, while proton torpedoes and concussion missiles are 4 times more powerful than that. But the turbo-laser on a Star Destroyer clocks in as a whopping megaton class weapon, with power equalling the Hellbores of Bolo.
    • When the Rebellion became the New Republic, they used their new-found wealth to buy Turbo-Laser artillery to deal with Imperial hold-outs. These were basically an anti-grav blimp with a Star Destroyer gun. One shot from this would punch through any fortifaction and instantly vapourize the near-invulnerable AT-AT walker.
    • In the now non-canon stories, the superweapon before the Death Star was the Torpedo Sphere. This was a mobile space station with large batteries of proton torpedoes. The torpedoes were used in mass against worlds that had planetary shields, but when the shields were down the Sphere would then use its real hitter: large batteries of turbo-lasers that would bombard cities and defense installations.
  • L.E. Modesitt Jr. uses the same magical Wave Motion Gun in two different series, The Spellsong Cycle and The Saga of Recluce: a magic spell which concentrates all the sunlight for dozens (or hundreds) of miles around into a destructive beam of energy.
  • The Expanse has a couple. In Persepolis Rising there's the Magnetar-Class battleship's main cannon, which shoots out a directed wave of magnetism so powerful it spaghettifies everything in its path. In Tiamat's Wrath, the Precursor Killers cause a neutron star on the edge of collapsing into a black hole to collapse, releasing a gamma ray burst so powerful it destroys the star's gate, the gate opposite that gate in the Slow Zone, possibly the star system that second gate led to, and everything that was in a straight line between them aside from the central station, which is left glowing for weeks afterwards.

    Live-Action TV 
  • Babylon 5:
    • The Vorlon Eclipse-class "Planetkiller" seen towards the end of the Vorlon-Shadow war.
    • The Great Machine on Epsilon III was hinted to be such, and certainly seemed to have the power to do it, but its ultimate purpose was never completely revealed.
  • The main weapon of the Victory-class Destroyers in the Babylon 5 spinoff Crusade is definitely an example: It's an incredibly powerful (and visually impressive) Vorlon beam weapon that draws so much power from a relatively underwhelming Minbari-sourced power plant (rather than the Vorlons' usual hyperspace tap) that it cripples the ship for a minute after firing.
    • Also, Earth Alliance has its own variation in the heavy particle beams mounted on combat satellites and the new Warlock-class advanced destroyers (which have two). The satellites had been already hinted to have it in Babylon 5 proper, and when they finally fired (here from 3.20) anything they hit was one-shot into oblivion. On the Warlocks, we only had Word of God about it for a long time, but in The Lost Tales we saw one firing, for obliteration of its poor victim.
      • According to the Expanded Universe, they acquired the design from the Drazi, a Proud Warrior Race with expansionist tendencies. Thankfully, they don't build warships large enough for it, so they only have it on defensive satellites and space stations, and gave the design to Earth during the Earth-Minbari War for defensive purposes (then again, Humans Are Bastards, and the Earth-Minbari War left them a bit scarred...).
  • Lexx:
    • The primary weapon of the 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.
    • In the very first minute of the very first episode, there's a rather hellish weapon (the Foreshadow, the flagship of His Divine Shadow) that eradicates the surface of a planet in about 5 shots.
  • The Star Trek: The Original Series episode "The Doomsday Machine" features a miles-long Planet Killer, a conical-shaped machine made of a virtually indestructible material that destroys planets and then uses the rubble to refuel itself. It was theorized by Kirk that the Planet Killer was created as a bluff to keep an all-out war from occurring, but that it somehow was activated and couldn't be stopped, destroying both its creators and their enemies before continuing through the universe. 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 — an impulse engine overload.
  • Star Trek: The Next Generation:
    • 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", in which it is used against a Borg cube. It doesn't work, though it would have — the Borg were forewarned and protected themselves against it. It also doesn't work the only other time it was used, to try to free the ship from a Negative Space Wedgie. Other than its complete failure in field testing, the deflector "cannon" features 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. You have to wonder whether the weapon would have fared better if tested on the Enterprise's sister ship... the USS Yamato.note 
    • 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.
  • Star Trek: Voyager:
    • In "Scorpion", Species 8472 combine the output of nine ships into one single wave of destruction — which even looks like a wave.
    • The Doctor uses a weapon called the "Photonic Cannon" during one of his daydreams in "Tinker, Tenor, Doctor, Spy". Obviously, the Voyager has no such weapon, but they later pretend to in order to scare off a superior foe.
  • Star Trek: Enterprise reveals the "verteron array" on Mars. Although primarily used to divert comets to the Martian ice caps, it can also fire a powerful beam of death anywhere in the solar system...which turns out to be a bad thing when an Absolute Xenophobe seizes control of it.
  • In Super Sentai, and by extension its adaptation Power Rangers, the heavier Humongous Mecha 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 team-wide Super Mode, as well as US-exclusive power-ups like the Battlizers, may or may not have these as well.
  • Doctor Who:
  • In the old German SF series Raumpatrouille, the starship has the aptly-named "Overkill" weapon capable of blowing up small planets.
  • Though not technically a gun per se, the wormhole weapon in Farscape fits this trope; it makes a freaking black hole.
    • Lo'La's Weapons Cascade.
  • The Ori put these as standard armament of their HUGE warships. These things can oneshot a Ha'tak with full shields as well as heavily damaging 304-class ships, potentially destroying them if they can land three hits. Combined with the freakishly strong Ori shields, these guns make Ori ships the spaceship equivalent of Physical Gods.
    • Asgard plasma beam weapons can also qualify since these are the only weapons known to be able to defeat even Ori ships. And unlike the Ori super-cannon, plasma beam weapons have the same rate of fire but are MUCH smaller to the point where at least four can be fitted onto a single 304-class ship, turning them into Pintsized Powerhouses.
      • These prove to be useless in the Stargate Atlantis series finale against the super-Hive, a combination of Wraith and Ancient tech. Given that even the Ori motherships can be fairly easily taken down with these beams, this makes the super-Hive the single toughest vessel in the known universe.
    • And of course there's the Ori satellite weapon. And the much bigger Lantean version that can literally cut a Wraith hiveship in half. Really, the Ancients are rather good at these.
      • The Asurans have a version of this that involves strapping a hyperdrive to a stargate and sending it to the target location, at which point an extremely-powerful beam is fired at their stargate back on Asuras. The power of the beam can keep the gate open indefinitely (beyond the usual 38-minute cut-off) and also powers the Nigh-Invulnerable shield around the "aiming" gate. Essentially, it's a weapon that can destroy anyone without ever leaving home.
    • The Eye weapon built by Anubis for his mothership is capable of fighting off an entire fleet of Ha'taks and destroying the surface of a planet.
  • 12 Monkeys: It's revealed in Season 4 that this is the true purpose of Titan, the Army of the Twelve Monkeys' city-sized time machine. Once completely and fully functional, it's capable of destroying the world simultaneously across every day of existence, creating a paradox so big that time would totally collapse.

    Music 

    Pinball 
  • Bally's Star Trek pinball game has the USS Enterprise(!) firing one from its front sensor dish.

    Tabletop Games 
  • Aberrant: Although characters are generally played at a much lower level of power, akin to your average Marvel Comics 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.)
  • Dungeons & Dragons:
    • The seventh-level spell Prismatic Spray mixes this with Beam Spam: a rather trippy, multicolored blast that can do (randomly) anything from setting foes ablaze to instant petrification. Among fans, it's popularly called "Taste the Rainbow!"
    • 3rd Edition's Epic Level Handbook introduces the epic spell Vengeful Gaze of God. It has a range of twelve thousand feet and is quite possibly the most powerful offensive spell in the entire game, dealing 305-1830 points of damage, enough to One-Hit Kill pretty much anything (including gods)...and also 200-1200 points of damage to the user.
  • Exalted:
    • The Eye of Judgment weapon from Titan-class citadels is not terribly resource-efficient, as it requires a crew of 5000 and the Eye is focused by an orichalcum lens a mile across, but the look on an enemy's face as a Titan citadel begins charging its weapon is easily worth it. Yes, someone with a perfect defence will survive, but the surrounding five miles or so will not.
    • The Godspear of the Five-Metal Shrike does, effectively, infinite damage at ground zero. If you have the right charms, though... you can block it.
  • GURPS Ultratech: At peak output, the Heavy Disintegrator Cannon can instantly vaporize 660 thousand metric tons of any substance per second. That's just the tank sized version, Spaceships has larger ones.
  • Jovian Chronicles has them in the form of the Valiant class patrol carriers. These ships, explicitly designed for groups of PCs in the vein of White Base and The Macross, packs a high powered laser in a spinal mount easily capable of outright destroying the heaviest capital ships in one shot.
  • Mekton Zeta:
    • You can build your own. Mega-Beam plus Charging Time plus Lots Of Kills Worth Of Damage...of course, it'll weigh about seven tons, take up all the space in both your arms, and/or cost a fortune in space efficiency, but just think what it'll do to whatever you point it at.
    • The ship construction rules have one already pre-designed — the Core Cannon. This takes three full turns to charge and inflicts 1000 Kills of damage. For comparison, a humanoid mecha built at middleweight scale can take maybe 60 kills of damage total (and a maximum of about 12K to any given component before said component becomes shrapnel) with another 60K in armour, meaning a shot from the Core Cannon could vaporise eight times over. Admittedly, with the size difference the Core Cannon is unlikely to ever hit a normal-scale mecha (that's what the Close-In Defence System is for). But it's still absolutely sodding huge and does huge amounts of damage, so it counts.
    • Thanks to the inclusion of Dragon Ball Z into the Fuzion system (which is directly derived from the Mekton edition of Interlock), Kills scale geometrically. 1,000 Kills is the structural integrity of a heavy striker type starship (about the size of the USS Enterprise NCC-1701, or a modern aircraft carrier). 3,200 Kills is the structural integrity of an Earth-type planet. 12,400 kills and you're one-shotting Jupiter. (reference: [1])
  • Rocket Age: The larger disintegrator rays; the Europans claim they either have enough of them in their fleet or a large enough cannon to wipe out the Earth.
  • Sentinels of the Multiverse:
    • Bunker is a hero so named because of his Powered Armor suit. One of his weapons is the Omni-Cannon, which he can charge up by putting three of his cards under it every turn. When he fires it, he destroys all the cards under it, dealing 2 damage for each. It can be one of the most powerful attacks in the game.
    • Omnitron, the giant self-aware robotics factory has one in the form of Disintegration Ray. While not as big or flashy as Bunker's, it can deal quite a bit of damage. Fortunately,it can be broken if Omnitron takes 7 or more damage in a single round.
  • Star Fleet Battles: Maulers, ships 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, less so otherwise.
  • Tales Of The Floating Vagabond has rather simplistic gun rules, however the most powerful guns are labeled "Don't Point That At My Planet!"
  • Traveller features "spinal mount" weapons, so named as they form the spine of the capital ships they are mounted on. In other words, the ship is built around this weapon. They are the most powerful weapons in the game, able to shred smaller ships in one shot (if they can hit: there are penalties for attacking sufficiently small targets), and at least one version of Traveller has details for a non-canon "superlaser" version intended (with sufficient scaling up) to model a Planet Destroyer.
  • Warhammer: The College of Light's Luminarks of Hysh are a fantasy version of this. A Luminark is a giant contraption made out of a chariot bearing an array of large lenses through which the device's attendant wizard casts a light spell called Solheim's Bolt of Illumination, which the lenses focus into a powerful ray of light that carves its way through whatever unfortunate enemies happen to be in front of it, dealing increased damage against daemons and the undead because Holy Burns Evil.
  • Warhammer 40,000:
    • The Blackstone Fortresses' combined-shot star-killing trick, even the single ship version of their warp cannon.
    • Planetside, any gun that fits into the Destroyer weapon class. Typically mounted on Superheavy vehicles, most typically Titans, they are the biggest guns on the battlefield. They don't care if you're insanely tough, incredibly well armoured, or seeking shelter behind a conveniently placed building... Destroyer weapons will vaporize everybody they hit, unless they have a force field that holds up or happens to be immune to being vaporized.
    • The monstrous Hellfury Cannon mounted on the Squat Cyclops super-heavy vehicle, from the second edition of the Epic gaming system, fires a stream of phased particles that react with each other to create a beam of pure energy that can destroy any target it hits. Even energy fields are little protection as the energy flux within the beam overloads them in swift succession.

    Video Games 
  • In Aquaman: Battle for Atlantis, Ocean Master's big plan is to destroy Atlantis's dome with his depth cannon gun.
  • Capcom vs.:
    • Whenever he's featured in a Capcom fighter, Iron Man has the Proton Cannon, a huge, shoulder-mounted weapon that shoots out a massive repulsor stream. Marvel vs. Capcom 3 adds the possibility to fire the beam at an angle upwards.
    • Mega Man's "Hyper Mega Man" hyper combo transforms him into a behemoth of a robot whose buster cannon fires a devastating beam that is nearly as wide as the screen is tall.
    • Morrigan's "Soul Eraser" creates a massive Arm Cannon that unleashes a powerful laser, accompanied by two Attack Drones that also fire lasers.
    • In Tatsunoko vs. Capcom, MegaMan Volnutt has his Shining Laser as a hyper combo.
  • A common staple of Command & Conquer games:
    • GDI's Ion Cannon in the Tiberium series, is an orbital satellite-mounted energy weapon. In first two games, it fired a focused blast upon a small section of the landscape, while in the third one the beam was followed up with a massive explosion enough to take out a modest-sized base. The Scrin also possess a more... low-flying version. It is just as much of a Kill Sat, but it slowly moves on the actual game map along with all other aircraft, rendering it vulnerable. But if it gets to your base, it can fire off the same massively destructive beams over and over.
    • Similar to the above Command & Conquer: Generals' as USA's Particle Cannon. It does differ in its firing mechanics - it fires up from the ground and uses orbital mirrors to bounce the beam to wherever you want it to go. Additionally, rather than providing one short burst, it creates a contiguous beam that can scrape across the map in order to take out several buildings in one shot. Oh and you can build multiples of them at once if you really want to rake over the enemy's base.
    • Command & Conquer: Red Alert 2, for the Allied Prism Tower and Prism Tank. The former can be charged up by other Prism Towers in range with tangible effect, while the latter's Prism Cannon has a flap on the rear which animates when the Cannon is shooting.
    • The Empire of the Rising Sun in Command & Conquer: Red Alert 3 has an interesting version in the Wave-Force Artillery. Besides the usual full power blast, it can be turned down for More Dakka. It's also their heavy tower, which likewise can be modulted to fire lower-damage bursts that recharge faster.
    • The Shogun Battleships, despite looking like a catamaran Yamato, don't use this (their special ability is to put on a burst of speed to ram enemies) but the Wave-Force Tricannons (used on their Floating Island Fortresses) do.
  • Crysis provides a rather hilariously underwhelming example of this technology when 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). 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.
  • The Savior boss's ultimate attack from Devil May Cry 4 is of this variety.
    • In the same game, Dante obtains a portable version in the form of the PF398: Revenge, one of the (seven of) 666 forms Pandora can assume. Any non-boss enemy on the receiving end of this laser is all but assured to be reduced to ash. Beyond that, whipping it out on the aforementioned Savior is one of the easiest ways to instantly incapacitate it so that Dante can go in for the kill. Have fun.
  • In Devil May Cry 5, if Dante has both Kalina Ann (hidden in an early stage) and Kalina Ann II (given to him late-game), he's able to dual-wield them and can unlock a Gunslinger move in which he combines them to fire off a massive laser.
  • It's standard for the Disgaea series to provide any unit that uses a gun long enough with a weapon skill that turns their normally modest weapon into one, Dark Filament from Disgaea 4 probably being the best example (And a Shout-Out to the original wave motion gun).
  • 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 Obvious Rule Patch doomsdays could be fired remotely, and did not disable jump-drives, making them complete game breakers.
    • In a more recent update, the Doomsday Device has been changed to a giant laser beam which is used to take out another, usually equally large, ship within a few seconds.
    • In addition, Jamyl Sarum of the Amarr Empire used a chaining Wave Motion Gun against a Minmatar Titan, destroying it together with it's support fleet. The gun is Lost Technology, 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 cutscenes.
    • The 11th patch/expansion, Dominion, will modified doomsday weapons to be, in the words of Eve blogger/podcaster Winterblink, "Macross cannons": In exchange for losing the AOE damage, they do massive damage to a single target via either a large energy beam (Amarr Avatar charges fires a literal Lazer, Gallente Erebus fires an antimatter beam) or a death blossom of enormous missiles (Minmatar Ragnarok, Caldari Leviathan). CCP has also hinted that more doomsday weapons are on the way...
    • ...which have arrived, as of the Citadel expansion. These include a conical area blast and a station-mounted chaining beam.
  • Final Fantasy uses this trope from time to time:
    • Final Fantasy V's Soul Cannon and GBA bonus boss Guardian.
    • The Final Fantasy VI and Final Fantasy VII incarnations of Alexander fire a laser from their mask; it's relatively thin, but it blows up the entire battlefield.
      • The Air Force boss and a handful of mechanical mooks have an attack called Wave Cannon that deals heavy lightning damage to all of its enemies. The Air Force uses it after its countdown completes.
    • Final Fantasy VII features a Mako Cannon, named "Sister Ray", built by the Shinra Electric Power Company for the sake of taking out the impenetrable barrier around Sephiroth. It is fired only once; Diamond Weapon stands in its way and 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.
      • 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.
      • The prequel 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.
    • The Guardian Force Eden in Final Fantasy VIII has an attack 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.
    • On the subject of Final Fantasy, Sin itself (from Final Fantasy X) should count, given the damage its Tera Gravitation attack causes to the planet when it is fired. Also, the machina that the Al Bhed and later the party use to attack Sin.
    • Final Fantasy X-2's Vegnagun, which Shuyin tries to use to destroy Spira. It was originally designed to help in the war between Bevelle and Zanarkand, but it was sealed beneath Bevelle when it failed to distinguish friend from foe.
    • Final Fantasy XII brings us the Mist Cannon, which is deployed at the end of the game against the Rebel fleet, to devastating effect, as it is capable of destroying A SMALL FLEET IN ONE SHOT. Doctor Cid also designed scaled-down ones so that he could personally fill rooms with laser-y death. To emphasize how powerful it is, the Superboss Omega can use their Wave Cannon attack, which usually takes many turns to power up, without charging.
    • Final Fantasy XIV has a few. Many Magitek enemies have Magitek Ray; the Cloud of Darkness retains her Particle Beam attack; and Omega uses Delta Attack to incapacitate Shinryu, and later uses it against the players as well. Several important dragon characters have an ability called Akh Morn, which is a cross between this and a Breath Weapon.
  • 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.
  • In Fuga: Melodies of Steel, the Taranis' ultimate weapon is the Soul Cannon, a massive energy cannon capable of wiping out any enemy in a single blast. There is a catch to using it, however: first off, it can only be called upon when the Taranis' HP is low. Second off, is requires that one of your crew of Child Soldiers consents to be used as the power source, dying in the process.
  • The original Galaxy Angel games (see Galaxy Angel gameverse) have the Chrono Break Cannon. It's so powerful that the Elsior originally had it removed, but the events of the first game have Moon Goddess Shatoyan decide that it'll be necessary to defeat Eonia, and it's used in the climax to destroy Eonia's flagship and later the Black Moon. In Moonlit Lovers, it's equipped on Unit #7 (piloted by Tact and his chosen Angel) along with a Chrono Field Canceller to disable the shield on Nefuria's ship, allowing them to fire it at point-blank range. In Eternal Lovers, Unit #7 is hijacked by Wein, who uses the Chrono Break Cannon to damage the Elsior, and later to try and destroy planet Juno (though in this case it's blocked by the Angels' wings of light).
    • In Galaxy Angel II, the Luxiole receives the Dual Chrono Break cannon, which as its name implies is twice as powerful as its predecessor. About two thirds into the final game, it's revealed that its two parts can be fired independently from each other by each one of the separate sections of the Luxiole, which is crucial to defeat Sorbet by firing at his vessel from two different angles to break through the shields.
  • Halo:
    • The Scarab is equipped with a Wave Motion Gun, which can be found by the player in plasma-rifle-size form as a Halo 2 Easter Egg, and is mounted on the "Beammaster" variant of the Grunt Goblin in Warzone Firefight. Notable in that the Scarab's gun was originally conceived for heavy excavation, until somebody in the Covenant realized that the huge stream of plasma meant to melt through and vaporize rock & ore could just as easily do the same to enemy vehicles and fortifications.
    • The Spartan Laser, an anti-materiel weapon that is used to destroy tanks...and aircraft...and turrets...and high-health enemies...
    • The Prophet of Regret's insta-death beam. The Hunters in Halo 2 and Halo 3 are equipped with a similar beam.
    • 343 Guilty Spark's death laser.
    • The Forerunner particle cannons found from Halo 4 onward. In one instance the beam is wider than several Pelican gunships flying in formation. It should be noted that it was used against three Pelicans flying in formation; of the three, one was brought down, and the other two were outright vaporized. Said cannons are also seen later one easily pulverizing UNSC ships.
    • From the same game, the Composer, which looks impressive, but doesn't actually do any landscape damage, instead painfully converts the biomass of any organism in its path into digital information, which is then forcefully embedded in a hardlight frame to produce a combat-ready AI.
    • Most Covenant capital ships mount at least one in the form of a plasma projector, capable of melting unshielded UNSC ships with ease. Said projectors can also be mounted on space stations, one of which heavily damaged the UNSC Infinity.
  • 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 Sucking-In Lines, and blast it in his chest, hoping that he doesn't stomp up and hit you while you're vulnerable.
  • In Heavy Weapon, you have the Megalaser, which destroys everything on the screen. You can collect up to four parts by destroying several enemies on the screen. It comes with a kick-ass wave-motion laser with an amazing sound and the guy screaming "MEGALASER!!!" once you collected all four parts.
  • Homeworld:
    • The Siege Cannon from Homeworld Cataclysm, which take 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, can be fitted to Archangel Dreadnoughts 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 Phased Cannon Array of the Dreadnought and Sajuuk from Homeworld 2.
    • Or just the good ol' Ion Cannons.
  • 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; 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 Dungeon Bypass.
  • Possibly Dan Smith's Collateral Shot from Killer7. 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 The Last Remnant, David's remnant is called the Gae Bolg. It Gaes hard, it Bolgs hard, and it's shaped like a giant penis!
  • Mass Effect:
    • Mass Effect 2 has the Collector ship's main weapon, fully capable of blowing the original Normandy in half with a glancing hit. Later in the game, you can get the Thanix Cannon, a recent Turian creation, which takes two shots to vaporize the Collector ship in kind. Both these weapons are watered-down versions of a standard Reaper weapon; the beam is actually a constant stream of liquid metal fired at C-fractional velocity. If that description doesn't scare you, look up C-fractional velocity, we'll wait. According to the codex, the Reaper version hits with around the force of 450 kilotons of TNT. To put that into perspective: the Hiroshima bomb had a yield of 13 kilotons of TNT. Not only that, but this cannon can be fired every five seconds and never runs out of ammo.
    • Mass Effect 3 has a weapon that combines the effects of two Mass Effect 2 Heavy Weapons (the Blackstorm Projector, and the Cain): The one-shot Reaper Blackstar; it is guaranteed to One-Hit Kill any enemy within it's enormous radius, and according to it's codex entry, it is thought to cause both a fission and fusion reaction.
  • One of the final weapons projects that a faction can research in Master of Orion II is the Stellar Converter. It's a massive ground based cannon capable annihilating even Titan class military vessels. If the player also researches Doom Stars, a Stellar Converter can be mounted inside. This grants a new option once the Doom Star has destroyed any fleets defending an enemy colony: destroying the planet entirely, leaving an asteroid belt in its place.
  • Metroid:
    • The Hyper Beam from Super Metroid, which is actually an attack taken from Mother Brain by the now-adult-sized Metroid that you saved on SR 388 in Return of Samus, who, after realizing you are its mother, gives it to you after draining Mother Brain of (most of) her energy. It is only used for a short time during the final boss fight and brings the once-powerful creature to its Yugo-sized knees.
    • The Hyper Beam returns in Metroid Dread when Samus fully taps into her Metroid powers, and it annihilates everything in its path. Just as before, Samus uses it to destroy the last form of the final boss and whatever gets in her way during the escape sequence.
  • In Koei's Warship Gunner series, basically Dynasty Warriors 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.
  • The #3 ranked assassin Speed Buster in No More Heroes wields a shopping cart... which transforms into an all-annihilating Wave Motion Gun.
  • 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 Sucking-In Lines) The Cannon was previously Dummied Out of another Bungie game, Marathon. All that survived in the data files was its name, leading to Wave Motion Gun WMG.
  • Radiant Silvergun: Many bosses, starting from the second one have at least one attack that involves firing a long-lasting wide laser that in some cases covers a lot of the screen.
  • In the RTS Rise of Legends, the Cuotl race have practically built their entire society off of Wave Motion Guns. Oh, and machines made of stone. But really the Frickin' Laser Beams.
  • 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, taking out an endgame-sized enemy in a single hit. It should be noted that, humorously, the guns are fired by pressing the helm of the ship like honking a car horn.
  • R-Type:
    • Just about every fighter in the 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 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 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. No Kill like Overkill indeed.
  • Sins of a Solar Empire:
    • The TEC's Novalith Cannon. 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.
    • Possibly the Advent's Deliverance Engine, which essentially fires weaponized love. Kinda.
  • The Egg Carrier in Sonic Adventure has one of these.
    • The Eclipse Cannon that first appeared in Sonic Adventure 2. Also, the Power Laser for Tails' and Eggman's mechs (battle mode and second enemy boss battle only). The former of which is advertised as being powerful enough to destroy planets when fully charged, and delivers as promised in Shadow the Hedgehog.
    • Sonic Battle: The Death Egg's Final Egg Blaster destroys A FLOCK OF STARS in a single blow. And unlike the Eclipse Cannon, it doesn't need even a single Chaos Emerald. Its sheer demonstration causes Emerl to go berserk, absorb it, and threaten to fire it at Earth.
    • Sonic Heroes: The Final Fortress features several of these. They are arranged in sets of three, and are Color-Coded for Your Convenience.
    • Smaller versions are also featured in Sonic 2 and Sonic 3 & Knuckles, aboard the Wing Fortress, Flying Battery and Death Egg.
  • 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.
  • Terran capital ships aka battlecruisers in the StarCraft universe are equipped with a Yamato Gun (naturally, named after Space Battleship Yamato), which fires a massive bolt of energy with massive damage in exchange for a large chunk of the unit's energy meter. This is easily acceptable, though, given the fact that the Yamato Gun is the only use for said energy. In story, it's referred to as a terrifyingly powerful weapon "capable of devastating entire cities" and taking out practically anything in just a few hits.
    • The battlecruisers actually fire a directed nuclear blast, basically Casaba Howitzers (see Real Life). The Yamato cannon creates a containment field, detonates a "small nuclear bomb", focuses the detonation, and uses it to propel a jet of plasma.
    • Protoss capital ships like the Carrier supposedly have this ability, though we never see it in-game until the sequel.
    • StarCraft II brings back the Yamato Gun (renamed to Yamato Cannon, and which now fires plasma instead of a nuke), and also has the Drakken Laser Drill (only seen in the campaign mission The Dig, though usable in the Co-Op missions as Rory Swann), a beam brought to break into [[Precursors Xel'Naga]] temple, which is so absurdly tough that it takes many minutes to melt through it when in comparison the Drill takes out a Protoss Archon, which has 300 shield points and great defense, in under three seconds - it takes longer to actually switch targets than to kill it. On the Protoss side we have the Void Ray, which should qualify as its initially decent attack becomes much stronger over time, and the Planet Cracker, a cut ability for the Mothership, and the in-game Purifer Beam, which basically does what sounds like.
    • Interestingly, the Yamato Gun seen in the game and in one cutscene (Emperor Arcturus I's acceptance speech) have different visuals. The version in the game is, basically, a big yellow-and-black pulsing blast that travels to the target. The cutscene version is a bright-red energy beam.
  • Squad 51 vs. the Flying Saucers have you facing the aliens' mobile hover-turrets, who attacks by firing a thick blast that covers a big chunk of the screen. If there's two or three turrets appearing onscreen, expect them to attempt crossing their beams together to take you down.
  • In Star Fox 2, Andross's battleships have weapons called "Planet Cannons". If they manage to reach Corneria and fire off a shot, the cannon will inflict a whopping 50% damage on Corneria, potentially destroying it in two shots and ending the game.
  • Star Fox 64:
    • Gorgon (the "Area 6" boss) with its giant rainbow laser (though it's simply red in the 3DS version).
    • And the Saucerer, with its Katina-base-destroying laser that takes a full minute to charge up.
  • You do battle against a Wave Motion Gun in Super Mario RPG, controlled by the evil Power Rangers-spoofing Axem Rangers on top of their blade-shaped Cool Ship (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.
  • Super Robot Wars:
    • In Super Robot Wars: Original Generation, the capital ship "Hagane" wields a massive, energy-guzzling 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 "Hiryuu Custom"'s Gravity Cannon and the SRX's Hyper Titanic Blasting Tronium Buster Cannon also count. Its full name, according to Ryuusei, is the Tenjou Tenga Ichigeki Hissatsu hou or Heaven and Earth One-Hit Sure-Kill Cannon.
    • Super Robot Wars W adds the Valstork's Double Proton Cannon, which can even link with the Valhawk to utilize it's Chest Blaster for even more power. The Dimension Breaker, the Chest Blaster of the Valzacard, by comparison, is its least powerful attack, which, by comparison again, is apparently the Valstork's Double Proton Cannon redirected.
    • In Super Robot Wars Z, Setsuko Ohara's final upgrade, the Balgora Glory, has the Gunnery Carver, which is powered by Break the Cutie. And is it ever. It comes in straight-line MAP attack form, damaging destroying every enemy in its path, made even more effective by the squad system the game employs, or it can use a Full Burst The Glory Star, complete with Pre Ass Kicking One Liner, to fire one of the most impressive beam attacks ever to grace the franchise, reducing the enemy to stardust with a spectacle of explosions.
    • Shin Super Robot Wars has the Hermodr's laser cannon, which destroyed a group of space colonies and acts the primary obstacle in the final scenario of the Space Route. It also appears in the Super Robot Wars Alpha series.
  • Super Smash Bros.:
    • Samus Aran's Zero Beam, her Final Smash, consists of an all-consuming, screen-filling beam that will (very likely) instantly KO anyone standing in its path. Unfortunately, it's so powerful it breaks apart her Power Suit.
      • She uses this Final Smash in the sequel as well, minus Samus losing her suit.
      • In Ultimate, Dark Samus has their own version of Samus's Final Smash, the Phazon Laser.
    • In the story mode for Brawl, 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 thereafter destroyed by Kirby, riding a tiny Air Ride Machine. Miniature airplane trumps world crushing battleship. Who'da thunk it.
    • Smash Bros has a lot of WMGs. Lucario's Aura Storm, Mario's Mario Finale, Ho-oh's Sacred Fire, Deoxys's Hyper Beam, Pokémon Trainer's Triple Finish, Mii Gunner's Full Blast...
    • The 3DS and Wii U iterations of the game add the Daybreak from Kid Icarus: Uprising. It requires one player to gather all three of its components at once, but its power is almost equal to Samus's Zero Laser.
    • Ultimate introduces King K. Rool, whose Final Smash is him firing his Blast-O-Matic from Donkey Kong 64 to destroy Kong Island.
  • Supreme Commander:
    • The Aeon Galactic Collossus and Cybran Monkeylord are experimental tier units that are expensive and slow, but can vaporize everything in front of them with, respectively, a giant phason beam and microwave laser. Cybran ACU itself can wield the main weapon of the Monkeylord too, while invisible to boot.
    • In the Forged Alliance expansion, the UEF got a Kill Sat with one of these. Its main strength lies in being unkillable due to being located in the orbital layer, out of range of all weapons - it can only be brought down by destroying its control center.
  • 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.
  • System Shock: The mining laser. One shot is enough to turn all of Central Florida to glass.
  • Space Manbow and Thundercross II have a boss that fires this throughout its level, and eventually uses it as one of its attacks when the player challenges it.
  • Touhou Project:
    • Marisa Kirisame's Master Spark and Final Spark spellcards certainly count, whether she's using them as your ally or your enemy. It also appears in the fangame Gensou Skydrift as Marisa's Last Word, where it has the rather odd effect of clipping through the level geometry, allowing her to hit opponents from a completely different section of the track if she uses it in the right spot.
    • Yuuka Kazami is actually the creator of Master Spark, which Marisa copied and modified. Aside from the regular Master Spark, Yuuka is also able to clone herself and fire two, albeit slightly smaller Sparks, an attack commonly referred to as the Dual Spark. Fanon occasionally also gives Yuuka a better version of the Master Spark, nicknamed Ultimate Spark.
    • Mima has the fangame exclusive Twilight Spark.
    • Utsuho Reiuji, whose incredibly powerful Arm Cannon is nuclear powered.
  • In Treasure of the Rudra, the Wave Motion Gun was used to kill the existing races on Earth.
  • Wing Commander:
    • Wing Commander: The Kilrathi Saga:
      • The Sivar dreadnaught from the Wing Commander add-on The Secret Missions mounts a gun that creates a gravity anomaly that increases gravitational pull 137 times, which is used to destroy the Goddard colony. The focus of the add-on is hunting down and destroying the Sivar.
      • The Concordia in Wing Commander II has the Phase Transit Cannon, a modified version of the Sivar cannon that is less powerful than the Kilrathi weapon from which it was derived but can be used to target warships, and is still powerful enough to destroy just about any ship with one shot. It has a tendency to not be available when most useful, however, and was removed from service shortly after the events of Wing Commander II.
      • The Behemoth from Wing Commander III is, like the Sivar cannon, a planet-killer, though using a Frickin' Laser Beam instead of gravity manipulation to do the job. The functionality of the gun beyond its initial test firing in the Loki IV system is unknown, however, as it's destroyed before it can be put to use against Kilrah.
    • In Wing Commander: Prophecy the Nephilim has the Kraken, whose plasma cannon can destroy an entire fleet in one shot. Later, it was equipped on the TCS Midway after being reverse engineered from a captured example, though the human version needed extra help to kill an entire fleet.
  • 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 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.
    • Don't forget the Durandal, which has beam weaponry capable of wiping out an entire fleet of Gnosis within seconds. And then there is KOS-MOS herself, who's pretty much a walking Wave Motion Gun. Her most powerful attack, the X-Buster, was one of the only few that got an in-battle video sequence in Episode I.
  • The Jehuty gets one in Zone of the Enders: The Second Runner, called the Vector Cannon. The player's mecha is frozen in place for half a minute while charging it up, but rest assured that whatever's on the receiving end of it will die.
    ADA: "Shift to VECTOR CANNON Mode. All energy lines connected. Landing gear and climbing irons locked. Inner chamber pressure rising normally. Life-ring has started revolving. ...Ready to fire."
  • The Mana Cannon from Tales of Phantasia and its prequel, Tales of Symphonia. Notable in that it is only used in cutscenes, rather than by the player, and also notable in being a horrible idea that almost always fails horribly. Turns out that a cannon shooting vast quantities of raw mana is a horrible idea when the source of mana only generates a finite amount and can be overstressed. The cannon is used four times over a roughly eight thousand year period.
    • The first use, in the backstory of Symphonia, goes apocalyptically badly, leading to a World Sundering and thousands of years of tyranny.
    • The second use, in Symphonia proper, breaks even, neither dooming nor solving anything.
    • The third use, between Symphonia and Phantasia once again goes apocalyptically badly, destroying advanced civilization and leaving the survivors to be knocked back to the dark ages by a meteor.
    • The fourth use, in Phantasia proper goes moderately badly, crippling the hero's side and setting back the sympathetic bit of the villain's plans. Why people keep thinking that reinventing and using it is a good idea is a bit of a mystery.
  • The Cetus Imera Photon Blast from Phantasy Star Online 2 turns the player's MAG into a biomechanical fish that fires a massive laser beam. Too bad it's aim is so god-awful...
    • In the Emergency Quest "Mining Base: Despair", players can operate a Mini-Mecha that comes equipped with one. A miniaturized version of said mecha's WMG can be used by players with Launcher weapons as a Photon Art called "Sphere Eraser".
  • The Capitol Ships from Empire Earth space age epoch has the DBoD or Devastating Beam of Death. It uses the game's Mana Meter so takes a long period of time to recharge. Longer than the duration of most space battles in fact. The prototype of the Capitol Ship was named, appropriately enough, the Yamato.
  • Space Pirates and Zombies has the Titan Beam, a true WMG with all the characteristics: It's useful, it's a laser, and it's required to advance.
  • Master of Orion II:
    • The Stellar Converter, which can only be mounted on ships of Titan class or largernote , is the most powerful beam weapon in the game, and can indeed be used to destroy entire planets. It can also be built on planets as a defensive weapon.
    • The most powerful beam weapon in the first Master of Orion, by a factor of ten, is the Death Ray. Obtaining it mid-game is very feasible (unless Orion is on the far side of the galaxy, or you're in the middle of a hot war and can't spare the battleships), and at mid-game tech levels the weapon is so large and has such high power requirements that one instance of it may or may not fit into an otherwise empty cruiser hull. It is also powerful enough to take out an enemy cruiser in one shot, almost regardless of shields or armour (extra-heavy neutronium will sometimes withstand it), and is the only beam weapon guaranteed to be effective against planetary defenses all the way through the game. 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 Master of Orion, the Stellar Converter is merely longer-ranged weapon, with no Earth-Shattering Kaboom effect on planets.
  • You don't get to use one in Gradius except maybe for the E-laser in Gradius V, 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).
  • Fraxy gives you the Laser in 3 different sizes and the Sonic Wave, which pushes people away.
  • 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.
    • The last mission of the expansion campaign features the Eclipse Super Star Destroyer, fitted with a weaker version of the Death Star's planet-busting beam. It can One-Hit Kill any ship and is very useful, since you have to fight both The Empire and the Rebel fleets. Conveniently, the beam stops working just as another SSD jumps into the fray, so you have to destroy it by conventional means. The Star Wars Expanded Universe novels indicate that the Eclipse could easily take on a large New Republic fleet on its own and win.
  • Another Star Wars example. The Mass Shadow Generator in Knights of the Old Republic. Turned Malachor V into a mass grave, killed most of the Mandalorians and all but one of the Jedi in proximity (and said Jedi had to go Force-deaf to survive it), and was so destructive that even the Mandalorians were horrified by it.
  • Ace Combat:
    • Not a laser, but Ace Combat 6: Fires of Liberation has the giant railgun Chandelier as its Final Boss. 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: The Belkan War, which is a laser, the Arkbird's laser cannon in Ace Combat 5: The Unsung War, and the Stonehenge railgun array in Ace Combat 04: Shattered Skies.
    • Ace Combat 5 and Ace Combat Zero also have unlockable planes with laser cannons as special weapons, the ADF-10A/F Falken in both, along with the ADFX-01/02 Morgan in Zero
    • Ace Combat 3: Electrosphere has Rena's X-49 Night Raven, with a laser that can destroy an island in one shot. The playable version is toned down though.
    • Ace Combat X: Skies of Deception has both a wave motion gun (the Shock Cannon of the Gleipnir airborne fortress) and wave motion missiles (the same fortress' Shock Wave Ballistic Missiles).
  • Air Force Delta Strike features the Leupold Battery of guns so large, you have to fly down the barrel to destroy it. There are three of them.
  • Armored Core:
    • Armored Core 4 has the Kojima cannons, massive Phlebotinum shooting beam weapons charged by Sucking-In Lines, that if they actually hit are an instant kill. Unfortunately, outside of two missions in for Answer,they're useless.
    • And in For Answer there's the Assault Cannon, Lethaldose, a Kojima Cannon of immense power that instead of having the traditional charge time of a Kojima Cannon, it uses your Primal Armor instead, which then takes a long time to recharge.
    • The series' signiature weapon, the KARASAWA (renamed CANOPUS) laser rifle, is one of these, generally the single most powerful energy weapon in its given game. In Armored Core 4, a middleweight craft wielding two of these can S-Rank the infamous March Au Supplice mission with ease, provided the player is experienced enough. Of course, in every game, they are severely hampered by their weight and the amount of energy they consume with each shot.
  • 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. Enemies must be captured and consumed in order to fire your Alpha beam, and certain powerful enemies will make your Alpha beam more powerful.
  • The above is actually a call back to a previous Taito game, Metal Black, which has a wave motion gun that can be charged by collection small power ups called newalones.
  • 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 though. The use of either of these weapons is pretty much the only thing which is outlawed on a galactic scale and will piss off any neighbors close enough to detect it.
  • This is in Space Channel 5, 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 Thunder Force 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 Game-Breaker.
  • X2: The Threat and X3: Reunion have the Phased Shockwave Generator, which is a Game-Breaker. 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 X2 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... (It is a heavy capital ship.)
    • The PSG was thankfully reduced to capital ship only in X3: Terran Conflict. Now the best contender for Wave Motion Gun is if you fit a Boron Thresher frigate with fixed forward facing Photon Pulse Cannons, which lets a player-piloted Thresher snipe capital ships quite effectively. A Thresher so equipped is a Glass Cannon however: in addition to the class having below-average shielding, you can get off maybe two or three blasts from your main guns before you've completely depleted your energy reserves.
  • 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 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 Astro Boy 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.
  • Kingdom Hearts:
    • Kingdom Hearts II:
      • The Surveillance Robot Heartless can be turned into one with the appropriate reaction command, spinning around and essentially vaporizing any enemy its beam hits.
      • The Storm Rider boss Heartless has an electric and stationary version of this as its ultimate attack.
      • Xaldin's strongest attack during his boss fight involves blasting the arena with a stream of wind resembling one of these.
      • Xemnas's ship form literally has an attack called Wave Cannon, a powerful wave of darkness.
    • Kingdom Hearts II Final Mix +: The Lingering Will can morph his keyblade into a giant cannon to shoot explosive bursts of magic at you.
    • Kingdom Hearts: Birth by Sleep:
      • The aforementioned "morph keyblade into giant cannon" attack is Terra's final Shotlock.
      • Vanitas has his own personal Shotlock called Dark Cannon, which fires a large beam of dark energy from his Keyblade.
    • Kingdom Hearts 3D [Dream Drop Distance]: For the Brawlamari Dream Eater's fight against Riku, it gains access to a huge laser beam, which Riku has to avoid by hiding behind a rock.
    • Kingdom Hearts III: Donald Duck unveils the Zettaflare spell, used only in a cutscene. It's a massive laser that outright obliterates Terra-Xehanort in one shot.
  • The Liberty cruisers of Freelancer are built around wave motion guns.
  • Planescape: Torment has the Mechanus Cannon spell, which opens a portal to a giant frikkin energy cannon and blasts your target enemy with it.
  • Warblade has a long string of different weapon upgrades Then, halfway through, they become fairly close to this. You have the standard single, double, triple weapons that appear all the time in other space-invader-style shmups, then quadruple fire. Then there is an upgraded triple fire, then plasma, which shoots a blue ball of energy, followed by fireballs (a wave motion gun in itself), then a laser, and finally upgraded plasma which is like normal plasma but has a wider spread and melts absolutely everything. And that's WITHOUT Super Autofire, which pretty much quadruples firing rate. It's probably safe to say that if you pick up a triple shot powerup if you have something really awesome, you are totally screwed.
  • The UIMS' Cannon Seed from Galaxian^3 Also Gourb from the PlayStation version
  • Ranger X features the Solar Mining Cannon, which covers 2/3rds of the screen and blows the camera forward instead of sending the eponymous Ranger backwards as might be expected.
  • The Spur, the Infinity Plus One Gun from Cave Story. At lower power settings it fires Frickin' Laser Beams, but its fully-charged blast is squarely in Wave Motion territory.
  • In Dungeon Fighter Online, the Launcher subclass actually gets two. One is his/her bread-and-butter Laser Rifle, which can be charged into not only a larger laser, but causes the rifle to expand. The other is a technique that starts off as 4 separate rotating beams, then merges into a more powerful one. Fired by a Kill Sat. Female Launchers, on the other hand, create a gigantic beam cannon that works as a more direct version of the above attack, while male Launchers later get a slightly smaller but even more powerful handheld beam cannon that they either rapidly sweep the room with before firing a blast that causes the ground to explode or quickly sweep once to gather all enemies in the same spot before firing an even more concentrated beam that errupts into a pillar of energy.
  • The so-called "Turbo Attack" from Gauntlet: Legends and Gauntlet: Dark Legacy. Although the Turbo Attack is actually a magic spell and not a technological device, it fits the trope in every other way.
  • The Particle Beam Smart Bomb weapon in Lightning Fighters.
  • The Fusion (and maybe Omega) Cannon in Descent.
  • The makers of Infinite Space sure love their WMGs. You've got both Krebs, the ZR, the ZR 2, Project Stetalumo, and that's even before you get onto the ones that you can actually use, namely the High-Stream Blaster (which is apparently an antimatter cannon) on the Corsair, Mayr and Evstafi, the Surface Blast on any number of ships (the Zanetti is the one that comes to mind) and the Meteor Plasma on the Freedom. Unfortunately, the ones you can use are a bit rubbish, and once you get to the later stages of the game, even one volley from your fleet is way more powerful, if much less awesome.
  • Raiden, the Big Guy/Brute in the Virtual-ON series, has this as its signature weapon.
    • Final boss Z-Gradt has the largest one of all, in which a giant cannon extends from its body and tracks the player. After a moment, it fires a giant beam that can severely damage any mech, and is particularly devastating to the more lightly-armored ones. As its health gets low, it can even fire this beam while still moving, and tends to back itself away into a corner to try and prevent the player from simply walking around it to dodge. Unfortunately (for Z-Gradt), it is extremely vulnerable to all attacks during this phase.
    • In the same game, hidden boss VR-Jaguarandi has a variation of Raiden's cannon, unforgiving on players that get caught in it.
  • The first Reactor Boss in P.N.03 is guarded by a pair of these, and getting hit results in instant death. The Seerose, Gardenie, and some of the Pilz are also equipped with a WMG-type charge-up attack. The Final Boss's second phase beam spams you with a dozen wave motion guns after it Turns Red.
  • The Leviathan from Conduit 2 is a gigantic sea serpent who shoots a massive laser beam from its mouth.
  • The Shock Beam cannon in Battleships Forever adds a damage multiplier to the base damage when fully charged, causing it to deal +150% damage while making the beam much larger.
  • The Legend of Dragoon has 2, the first one being the Black-Burst dragon's shadow cannon, and the second one being the infamous divine dragon cannon.
  • The Tale of ALLTYNEX series uses this in all three games in various shapes and forms. A special note goes to the ZODIACs, whose laser blast sometimes cover the entire screen.
  • Hellsinker:
    • Stage 6 features a huge beam coming from the bottom of the screen as a setpiece. While the player isn't in control of the beam, enemies also take damage from being hit with it, and it can be used to break through walls or even kill the midboss.
    • Kagura's "Xanthez" discharge has the shortest duration of any discharge in the game but is also the most powerful.
  • Three major versions exist in Escape Velocity Nova. There's the Vell-os psionic weapons, including the "turreted" Autumn Petal and the even-deadlier fixed Winter Tempest. The Aurorans get in on the action by importing Vell-os tech, applying their standard Tim Taylor-meets-Worf design scheme to it, and create the Thunderforge dreadnought and its "Triphammer" main guns (also qualifies as an example of More Dakka). Meanwhile, the Polaris Capacitor Pulse Lasers were just as deadly as either and vastly more common, being mounted on all their capital ships save the Dragon (frigate analog).
  • Frontier: Elite II, Frontier: First Encounters, and Elite Dangerous have the Plasma Accelerator, a Wave Motion Gun that comes in two sizes, Small and Large.
  • The Brahmastra from Asura's Wrath It and the Karma fortress it resides in are powered by human souls. It ends up being fired twice: Once at the intended target, Gohma Vlitra, a continent-sized monster that the Guardian Generals/Seven Deities have been fighting for eternity. All it does is piss Vlitra off. Later, it gets fired at Berserker Asura, who by this point is singlehandedly destroying the Deities' entire fleet. It manages to damage Berserker Asura's extra arms and force him into the less overly destructive but still horribly powerful Wrath form.
  • The Pokémon games have some, the most known of which is probably Hyper Beam and its variations. Due to its nature, most are more likely to use the more practical wave motion guns available to them such as Flash Cannon, Dragon Pulse, and Solar Beam (in the sunlight), etc. Needless to say, the franchise has built up a Wave Motion Arsenal.
    • There are also a few Pokémon themselves with bodies that function or look like powerful beam cannons: Clawitzer has a gigantic claw, bigger than the main body, that shoots energy projectiles; Vikavolt and Alolan Golem have protrusions on their bodies (mandibles for Vikavolt, shoulder mounts for Alolan Golem) that resemble and function like electric Railguns; and Regidrago's battle stance has to going up into the air and positioning its arms to look simultaneously like a dragon's head and a large beam cannon, with a Signature Move, Dragon Energy, in the form of a huge laser beam. Mega Blastoise is a borderline case, with one huge cannon coming out of its back rather than the three iconic cannons in its shell, and while it can fire energy projectiles too, Mega Blastoise is more closely associated with large amounts of pressurized water than the usual application of this trope.
  • In Tales of Eternia, Fog/Max's Elemental Master arte turns his gun into one by firing a laser that covers the length of the entire battlefield and almost reaches the top of the screen.
  • Tales of the Abyss has two: Anise's X-Buster and Luke's Lost Fon Drive.
  • In Mana Khemia: Alchemists of Al-Revis this is one of many features built into Flay's mechsword.
  • In Skies of Arcadia, when you fight DeLoco for the second time, his ship has a Moonstone Cannon prototype that unleashes a giant yellow beam of death. Once you get your own ship, it comes with the finished version.
    • The Galcian Battlestation: Hydra comes with an improved version of the Moonstone Cannon.
    • Silver Gigas: Zelos comes with 2, a small one at the beginning of the fight and a much larger one after it transforms.
  • Various monsters in Monster Hunter are capable of using deadly beam attacks that are often unblockable without the Guard Boost armor skill. Common elements for these beams include Fire, Ice, and Water.
  • In Kongai, Angelan Series D's long-range attack is a Wave Motion Fist. But it's not that big.
  • The alien ship's death ray in Fallout 3: Mothership Zeta. At one point, the aliens fire it on Earth. In the quest's final battle, you use it against another alien ship. The Tesla Cannon in Broken Steel is one of the smaller man-portable type.
  • The Sectopods in XCOM: Enemy Unknown are equipped with no less than two. They are smaller than most examples, but since they're only being used on modern humans and their technology, that's perfectly fine. They are one of the most powerful weapons in the game (second only to the claws of a Berserker), and what makes the WMG's really bad is the Sectopod's ability to fire twice in one turn at separate targets AND set up Overwatch to shoot any of your soldiers if they move. Combined with their health (highest in the game) and high defense that makes it hard for your troops to hit, and you have the strongest, most feared enemy in game.
  • The "Hellball" spell in Neverwinter Nights 1 probably qualifies for this trope because it's the most powerful Area Of Effect spell in the game and although it acts as a Guided Missile, it takes time to reach the enemy giving them time to kill you first, and also if you don't back off immediately after casting, you'll be caught in the blast and suffer its effects as well.
  • A few enemies in The Binding of Isaac have wide beam attacks, particularly Gluttony, who rips open his chest and apparently fires a massive beam of his own blood. The player can get this attack for themselves with the Brimstone power-up, and it is quite deadly in exchange for charge time. Combine it with Polyphemus, and you get a beam of destruction that takes a painfully long time to charge, but One-Hit Kills all but the toughest bosses (and the fact that you can charge a Brimstone laser before you enter the next room usually eliminates the charge time problem as well.) You can also find a power-up called Shoop Da Whoop, which does exactly what you'd expect.
  • Omega Boost: Lester uses one of these in the opening cinematic, but you don't actually get one in-game.
  • Star Trek Online: The Galaxy Dreadnought Cruiser, a copy of the three-nacelle Enterprise-D that appeared in Star Trek: The Next Generation: "All Good Things...", features a spinal phaser lance that can do incredibly high amounts of damage ... if it hits. In practice it's decidedly Awesome, but Impractical: Its firing arc is narrow*, its accuracy is horrible, it causes massive weapons power drain, it has an absurdly long cooldown, and it basically locks you into using phasers for your primary weapons if you want to max out its damage.* Not to mention min-maxers have duplicated its high damage with the much more usable Beam Overload bridge officer skill.

    To add insult to injury, the Nausicaan Guramba Siege Destroyer has a similar disruptor javelin which is almost as damaging but has a third of the cooldown and no accuracy limitation, making it much more usable.
  • Star Trek: Klingon Academy: The largest Federation and Klingon dreadnoughts are equipped with the "Assault Phaser". A forward mounted heavy beam cannon that can punch through shields or punch through hulls where shields are not available. The Federation dreadnought, the appropriately named Yamato-class, is equipped with two. Starbases also have multiple weaker versions of this weapon.
    • There's also the AMFP (Antimatter Field Projector), which takes the form of one of these.
  • The Artillery Beam from FTL: Faster Than Light takes up an entire room separate from your other weapon systems. The thing pierces shields, and takes up the slot where your cloaking device ought to be on a similarly-sized craft (before the expansion). It takes nearly a full minute to charge up, and fires automatically.
    • On the conventional weapon side, the Glaive Beam is one of the few weapons to take four power bars to activate, and is the slowest weapon in the game barring artillery systems at 25 seconds base. While it doesn't pierce shields, if you get the enemy ship unprotected before firing it deals three damages per room hit, which, if properly aimed, will probably One-Hit Kill the other ship.
  • The Fusion Beam from Space Pirates and Zombies can drain your ship's capacitor very quickly, and fires continuously for a lot of damage. In fact, it needs to be augmented by a Leech Beam, lest it leave you defenseless. The Leech Beam actually compensates very well for the fusion beam's massive power drain; as two can keep you going with every other slot filled by a fusion beam.
  • In Borderlands: The Pre-Sequel!, the center of the Helios station (a giant satellite) houses a laser, also known as the Eye of Helios. It's later revealed that it's powered by the eye of the Destroyer, the Eldritch Abomination that served as the Final Boss of the original Borderlands, prompting Moxxi, Roland and Lilith to sabotage it.
  • Several bosses and heavy enemies in Vanquish have these, usually lethal in one hit. The Romanov's Chest Blaster variant can pass through cover objects.
  • MechWarrior generally relies on relatively "normal" sized lasers (well, normal for Humongous Mecha), but the Heavy Large Lasers in Mechwarrior Living Legends are scalpels of death; they scythe through even the toughest armor with alarming speed, use a long-duration continuous hitscan beam laser, emit a deep rumble, and pump out enough heat to melt the vehicle they're mounted on with careless use. The Morrigu, an 80 ton siege tank, can mount three Heavy Large Lasers, which can gib a light mech in a single salvo. It's highly recommended to Alpha Strike when only completely submerged in water, as air doesn't dissipate the weapon's heat fast enough to prevent overheating damage.
  • Half-Life has two of them:
    • The Tau Cannon fires somewhat slowly, but does a lot of damage. This gets magnified if you use the charged shot. Just before obtaining it, you can overhear a scientist and a security guard getting reduced to Ludicrous Gibs due to the latter's callous handling of this. Incidentally, it returns mounted on the scout car in Half-Life 2.
    • There's also the Gluon Gun, essentially a backpack-sized nuclear reactor that is quite capable of chewing through enemies fast and its ammo supply (shared with the Tau Cannon) faster.
  • The final part of the game before the Final Boss in Freedom Planet has the player travel up the inside of a Wave Motion Gun on Brevon's ship and having to hide in safe spots while it fires (taking the full blast is easily a One-Hit Kill.)
  • Steredenn has bosses, regular enemies, and even the player using these, in the form of huge, charged laser beams.
  • The Assaultrons in Fallout 4 have Wave Motion Eye Beams that can kill the player in one shot.
  • These are employed by the final boss of the Genocide Route in Undertale, in which they are known as Gaster Blasters.
  • The Particle Lance and its upgrade, the feared Tachyon Lance of Stellaris. The capstone of the beam weapon tree, the Lances can only be mounted on the largest hardpoints of the greatest capital ships and devour an obscene amount of reactor power. They also tear through armor, have enough range and accuracy to be fired from across entire solar systems, and deliver simply grotesque amounts of raw damage with every blow.
    • The Titan Laser. Employed exclusively by Fallen Empires, they'll vaporize virtually any player-made ship in one shot.
    • The planet-cracking Colossi could be said to have these, though they're remarkably short-ranged for such an endeavor. But if you're willing to use mods, the Gigastructural Engineering mod offers perhaps the ultimate example of a wave-motion gun in the Nicoll-Dyson Beam: An entire young star turned into a giant beam cannon capable of destroying planets from many, many star systems away.
    • Gigastructural Engineering later one-upped itself with the Quasi-Stellar Obliterator, which can only be built around the supermassive black hole at the core of the galaxy. It is capable to annihilate not only planets, but also stars, and even entire star clusters (a star and all adjacent systems) at full power.
  • In Overwatch, Hanzo's ultimate ability, Dragonstrike, is a beam of two huge intertwining dragons (or wolves, with the right skin) that go through walls, do continuous damage to any character in contact with them, and keep going until they hit the boundary of the map. (Although most of the time they'll have gone off into the sky or into the ground by then and no longer pose a serious threat.) Being caught in a Dragonstrike will reliably kill most characters including tanks unless they can get out of the way immediately after they start taking damage, have a temporary invulnerability ability like Reaper or Mei, or are protected by Zarya's barriers or the massive amount of healing from Zenyatta's ultimate.
  • The Lancer class of Distant Star Revenant Fleet carries no weapons, but has, as it's special ability, a powerful laser cannon. It's intended to be used as a sniper.
  • Sunrider:
    • The titular ship has the Vanguard Cannon, a beam so powerful that it can obliterate almost any enemy caught in its path and can destroy multiple targets in a single shot. A special cutscene plays whenever you give the order to fire it.
    • Big Bad Veniczar Arcadius's flagship Legion has an even bigger one that he uses to nuke cities from orbit. When fought as a boss, its beam is a One-Hit Kill to any of your units that don't get out of the way before it fires.
  • In The Legend of Zelda: Breath of the Wild, any Divine Beasts you have liberated will fire utterly massive lasers at Hyrule Castle, taking out 1/8 of Ganon's health bar per beast (for a total of half if you freed them all) in a burst of glorious light. The lasers are each as large as one of the castle's towers.
  • In Subnautica the game's story is kicked off by your ship being shot down by one of these, and further driven by your efforts to turn it off so you can leave without being shot a second time.
    • You actually get to see what this weapon can do if you're standing on the beach by the Quarantine Enforcement Platform when the Sunbeam attempts to come in for a rescue. Seeing your first hope of rescue be taken out like that is... Hard.
  • In Octogeddon, both the Stomp-A-Tron X and The White House use one to attack Octogeddon.
  • Call Of Duty Infinite Warfare: F-SpAr (Focused Spectral Array) cannon installed on the Olympus Mons, it can one-shot most other ships. In one of the final missions, the player controls it.
  • TerraTech has the Hawkeye company's AKIRA railgun. Although it fires in short bursts, the railgun deals more damage per shot than any other energy weapon in the game.
  • Nexus: The Jupiter Incident has the siege laser, a Fixed Forward-Facing Weapon mounted first on Gorg battleships and then, after the ceasefire, on Noah battleships as well. It's an extremely powerful weapon that can punch through any shield, including the massive fort shield, and deal heavy damage directly to the hull. It also has incredible range. However, in order to fire the weapon, the battleship must use its entire power supply, plus that of two other ships. When the siege laser is charging or firing, the three ships are locked in place with their shields dropped and can't do anything else, including maneuver, so if the target manages to get out of the way, the three ships have to maneuver while maintaining their formation.
  • In Shining Force, the party encounters an ancient superweapon called the Laser Eye. It takes several turns to charge, and after the countdown is complete, it fires a wide beam of light that causes great damage to all units in its path, including your enemies.
    • This scenario is repeated in Shining Force Gaiden II: The Sword of Hajya with the Statue of Iom. Instead of navigating a narrow rock bridge as in SF I, you have to navigate a narrow canyon and use the few hiding spots you can find to dodge its beam when the crystal turns red.
  • Warframe:
    • Grineer Balor Fomorians, which are capital ships, carry huge laser cannons with a charge cycle and a low rate of fire that can blow up capital ships and space stations in one shot. Several Tenno Relays met their unfortunate end at a Balor's hands.
    • Tenno Railjacks — smaller, four-man spaceships — have a Fixed Forward-Facing Weapon, the Tunguska Cannon, that can vaporise other ships of similar size, overkill single-person attack craft, and even destroy capital ships if it hits weakpoints. Fittingly, as you charge it fires six lasers into a single point before firing off the unified blast.
  • Viy fires off a bunch of these in La-Mulana, though their main effect is to disintegrate the platforms, making his eye harder to hit. Later on, Tiamat fires off seven at a time, and if Lemeza even so much as clips the edge of one, he might not be killed in one hit, but he'll be hurting.
  • Armored Hunter GUNHOUND EX: Players can unlock one in the form of the Anti-Ship Energy Cannon, which can be unlocked by scoring a total of 30,000,000pts.
  • Doom Eternal has the BFG-10000, an orbital defense cannon stationed on Phobos powerful enough to shoot a hole into Mars and uses the BFG-9000 (which is more of a Lightning Gun than a WMG) as a power source. There's also a smaller Ion Cannon nearby, which the Doom Slayer uses to Human Cannonball himself into the freshly-created hole in Mars.
  • O.N.G.E.K.I. which is part Rhythm Game and part Bullet Hell, features laser blasts as enemy attacks in a few songs. "conflict" is well known for a section where multiple lasers come down followed by a massive beam down the central lanes as the second refrain kicks in, in reference to the original music video.
  • Star Wars: Squadrons has the Composite-Beam Cannon, a weapon for bomber-type starfighters that converges two beams together to fire a powerful green laser that can make short work of smaller capital ships while also wreaking havoc on the subsystems of larger ships.
  • Nox The fully empowered Staff Of Oblivion. It does about 300 damage per second and always hits as long as you are facing in towards the target(s). Right after you get it Hecubah shows up with a veritable army of Mooks which you can still wipe out singlehandedly. The only downside to the staff is it can run out of mana, and the area helpfully has a bunch of mana crystals. Against Hecubah in the Final Boss fight, it's not quite the "I win" weapon it is against mooks, but is still the best thing to use on her (unloading it on her when it's fully charged does around 250 damage.
  • Beam weapons in Next Jump SHMUP Tactics require four units of energy to fire, and cost 8 units of scrap to boot. For context, that's all the energy a ship can hold without an Extra Battery accessory. They are appropriately flashy and powerful, firing a 4-space long laser beam. They come in Hull and EMP variants.
  • In Bloons Tower Defense 5 and 6, The Ray of Doom is the final upgrade of the top path of the Dartling Gunner. It fires a powerful beam that pierces a lot of bloons and deals a large, constant amount of damage to anything it touches, typically destroying most of the less powerful bloons in seconds.
  • In each of the Destroy All Humans! games, the most powerful weapon on Crypto's Flying Saucer is the Quantum Deconstructor, which fires a mammoth energy blast capable of annihilating an entire city block in one shot.
  • The Acceleration Blast from the Blaster Master series often shows up as this. It is the epitome of Awesome, but Impractical in terms of gameplay - with completely full weapon energy, you have to sit completely still as you charge it up, and being hit by an enemy will interrupt the charge, but once it fires, you can safely kiss every mook and most bosses in front of you goodbye. The Invem Sophia knows how powerful this weapon is and, unless it's firing its own, it will dodge the attack by literally flying out of the arena. Every Skeleton Boss incarnation, and every boss that makes use of the Gaia System, will go down in one hit from any variant of this weapon, but the latter group must exhaust their energy reserves before that can happen.

    Webcomics 
  • Cloudscratcher: Agathoth creates a weapon that, just from a test fire, turns an entire mountain into a smoldering wasteland. It's so powerful, it uses an energy source previously thought to be infinite, and completely drains it.
  • Homestuck: Eridan's laser rifle, Ahab's Crosshairs, fires very powerful, very large energy beams capable of killing anything they strike.
  • Stolen Generation: The Phase Transition Guns. One the size of a pistol can easily shoot down a futuristic fighter jet going at mach 10.
  • Suppression: The Doomsday Crush Cannon fires a destructive red beam wider than a person is tall.
  • Bob and George: Dr. Light has a Wave Motion 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!
  • Angels 2200: Ship to ship combat seems to consist of capital ships firing their particle beams, powerful laser cannons that can blow right through another ship, at one another, then letting the fighters duke it out while they wait for the beams to recharge.
  • Schlock Mercenary:
    • King LOTA's favorite toy can shoot you from the other side of the galaxy, through a wormhole, as long as LOTA has targeting information. Shields won't help, either, but not because it'll punch right through (though it certainly could), but rather because it bypasses them entirely.
      Kevyn: This is where I defecate in sympathetic reflex for every defense planner in the galaxy.
    • Additionally, the other end of the wormhole can be opened up inside solid objects, meaning the Long-gunner of the Apocalypse (LOTA), can destroy them from the inside out.
      Narrator: A fusion hot lance of anti-protons is a good tool for burning holes through hundreds of meters of hull. But firing on a point inside the armor and letting the beam find its way out? That's where it gets magical.
    • The Toughs acquire their own miniature version of LOTA's cannon from the Neoafa. It's mounted on a corvette-sized ship and can fire through (or rather, past) any known form of defense. However, it also uses up the ship's entire fuel supply in one shot,note  permanently irradiates the compartment it is mounted in, requires very precise targeting data and is also likely to attract far too much of entirely the wrong kind of attention.
    • These guns later become sort-of mass-produced, now referred to as Long Guns in 'honor' of King LOTA. Since they are so powerful there is literally no defense against them, the only thing holding the galaxy together afterwards is a mixture of ignorance and Mutually Assured Destruction between LOTA and the Neoafa. Petey is entirely unhappy about this, because the failure state is not something he likes at all, and there's always someone that doesn't care if they die and take the universe with them if it means their enemies die too.
    • Someone who doesn't care for reasons closer to immunity/formlessness eventually gets a hold of the technology, and builds the single biggest of them all. The Pa'anuri Hypercannon quickly becomes the longest-ranged, and biggest, weapon in 12 million light years around, capable of destroying anything there is so long as they have targeting data, and its wielders are sociopathic enough to simply keep taking potshots as they get closer to their real targets. This, of course, requires such absurd amounts of energy that when targeting data is hacked and it shoots itself in the back, the ensuing explosion could be mistaken for a particularly large Supernova.
    • One of Tagon's ships gets a more "conventional" wave motion gun that simply fires gravity-braided plasma, at close range it tears straight through shields.
  • Wayward Sons: With a minor modification and application of his power, Airez has turned his sidearm into one of these.
  • Girl Genius
    • The Death Ray Agatha built while in the Castle blew a hole through the fortress wall, the roof of one of the towers and the mountain a mile or so away.
    • As can be seen in this page, someone saw fit to equip a swan-shaped party sleigh with one of these, complete with it looking like the swan's Breath Weapon.

      Ishtvan: Could it always do that?
      Tweedle: How should I know? Knowing my grandmother's parties, probably.

No-one really wants to think about what sort of opponents would be so terrifying that a weapon that appears to worry even the archai was needed to defeat them.
    • As befits is quite hard sci-fi nature, the Thunderbolt was based on real-world theoretical physics, see below.
  • One of the weapon Hilda gives to X-Ray & Vav in the first episode of their eponymous series is a teacup whose true functions are unknown.

  • Battle Action Harem Highschool Side Character Quest's main viewpoint character, Anna Sanchez, has one. Or more accurately, she's using her Impeller field manipulation to simulate one via a process that involves poking a hole in the fabric of reality and focusing the catastrophic effects of doing so into a blast of energy. this leaves her with her shields down and missing an arm every time she does it. This whole process is called Wave Force Manipulation. The UN's attempt to recreate Wave Force involves a gigantic cannon on the moon.

The end result is a railway cannon capable of blasting a molten hole straight through a small mountain that is equipped to the arm of a Humongous Mecha.
  • Rose Quartz's laser light cannons from Steven Universe, which are shaped like giant roses and fire a beam of light shaped like a beautiful dancing women, but which are incredibly destructive, nonetheless.

    Real Life 
  • Hypothetical real-life Wave Motion Guns would utilize nuclear weapons as ammunition. There are several proposed variants of the concept:
    • The most famous is the Casaba Howitzer, also called a nuclear shaped charge. Basically, instead of wasting almost all of of a nuclear weapon's output in an omnidirectional explosion that would mostly miss the target, a bit of engineering ensures that a good 1 to 50% (depending on design and yield) of the energy is radiated into a cone, by using the nuke's energy to propel a solid mass. Most of the details have never been declassified, but as spin-off of Project Orion would be using technology decades old now. The original nuclear shaped charge concept called for a tungsten jet to be converted to a jet of plasma and propelled at tens of kilometers per second with a very wide cone angle of ~22.5 degrees. It was to be used as propulsion, and could supposedly focus 80-85% of a nuke's yield.
    • Also part of Project Orion was specific attempts to weaponize the concept, instead of just using it for propulsion. It was found that they could decrease the beam angle (theoretically) to a minimum of 5.73 degrees, and increase the velocity of the plasma jet to 280 km/s, by using a material with lower Z than tungsten. Up to 50% of the energy would be converted. Though this would only support a yield of a few kilotons and would still only be useful at a very close range. The Third Generation Nuclear Weapons Study out of Princeton also speculated that we could theoretically create a 'plasma howitzer' Casaba that propelled the jet to 1,000 kilometers per second with a cone angle of 0.57 degrees. Such a weapon could maintain 10% efficiency up to about one megaton of yield, after which efficiency rapidly degrades due to bare physical laws and the concept ceases to be practical.
    • There is only one known variant of the Casaba Howitzer concept to actually be tested: the Chamita test of 1985, part of Project Prometheus. Instead of utilizing a 'plasma howitzer' with a wide cone angle, the Chamita test attempted to focus its energy down a shaft to power a particle beam. The study stated that a small nuclear bomb could have up to 5% of its energy converted to kinetic energy in the form of propelled particles launched at about 100 km/s (at 50 kilotons of yield, this decreases to 1%, and it gets worse from there, so like the plasma howitzer the concept doesn't scale up particularly well). It was partially successful - the yield of the device detonated is unknown, but it managed to accelerate a 1 kilogram mass of tungsten to a velocity of 70 kilometers per second, for a total of 0.58 tons of kinetic energy. More importantly, the beam had a very small cone angle of 0.057 degrees, meaning it could be used at a much longer range than either the original concept or the plasma howitzer (against a non-maneuvering target, anyway), though the concept accommodated lower yields and even lower efficiencies for said yields.
    • Bomb-pumped lasers would instead use the nuke to power a single-shot bomb-pumped gamma-ray laser using hundreds of laser rods. This weapon was extensively studied, but suffered from Crippling Overspecialization: less than 0.00001% of the bomb's yield could be converted into a laser (in other words, using a 100 kiloton bomb would get less than one percent of a single ton), and the range would be limited to <100 kilometers. So why would you use such a weapon instead of just detonating the bomb? Well, as it turns out, it'd be pretty useful as a one-shot point-defense system for shooting down thin-skinned ICBMs... at least in theory.
    • It appears that directed nuclear weapons in general are Awesome, but Impractical, at least compared to what future-obsessed nerds think them capable of. The Princeton studies explain why:
    Third Generation Nuclear Weapons Study: "There is also a fundamental problem with both the Casaba and Prometheus concepts that becomes relevant at higher yields. Despite the alleged success in directing 5 percent of the energy of a small nuclear explosion into flying debris, a good portion of the remaining energy inevitably becomes blackbody radiation, which would quickly overtake the pellets. Even at 1 kiloton with optimistic assumptions, this poses the risk that most of the particles will be vaporized or even ionized, rendering them ineffective. The NKEW concept is thus one that may require subkiloton explosives to be feasible. If its feasibility also depends on employing shaped thermonuclear explosives to help direct the pellets or dust more efficiently, then the concept is further burdened by the difficulty of designing thermonuclear devices with yields less than 1 kiloton. Whatever the case may be, it is clear that demonstrating a rush of hypervelocity pellets from a nuclear blast, while perhaps impressive, in no way guarantees that a useful weapon will ever be derived from this concept."
    Fourth Generation Nuclear Weapons Study: "However, as most of the energy absorbed by the projectile will contribute to heating rather than accelerating it, the projectile may not go very far before disintegrating — unless only the rear part of the projectile is heated, and therefore acts as a working fluid pushing the front part ahead by rocket-effect. Thus, as can be seen from this example, the practical design of thermonuclear-driven devices is most likely to be very complicated, so that the discussion presented in the following subsection has to be understood as a description of idealized concepts."
  • Combine Wave Motion Gun with Beam Spam with Recursive Ammo and you get Project Excalibur, a theoretical X-ray laser Kill Sat powered by a nuke going off that Edward Teller thought up for ballistic missile defense. Eventually folded into SDI, but never left the drawing board after disappointing preliminary tests with X-ray lasers. It is quite possible to combine multiple shaped charges or explosively formed penetrators, as well as bundles of xraser rods, in one nuclear package. No Kill like Overkill, indeed.
  • Some space objects (dying supergiants or neutron stars colliding) can produce what is called a Gamma Ray Burst, basically two humongous lasers shooting out from opposite sides.
    • At least one star capable of producing a GRB is pointed at the Solar System, is extremely old, and may fire it off in the next 200,000 years.note  Talk about massive Energy Bursts. Some scientists think that a gamma ray burst is what killed off the trilobites and their cousins and made way for the fish to dominate the seas.
    • Excellent real-life example of what an unusually powerful GRB is capable of: the Oh-My-God particle. This is a proton with 300 EeV kinetic energy and speed 99.99999999999999999999951% of lightspeed (to quote The Other Wiki: "in a year-long race between light and the cosmic ray, the ray would fall behind only 46 nanometres") which in particle physics is simply unholy - energy equivalent to a baseball flying at 95 KPH. In a single subatomic particle. "Oh-My-God" indeed.
    • To date, the most distant GRB ever detected was 13.14 billion light-years away, making it not only the most distant GRB ever spotted, but also one of the most distant objects in the entire universe. Now that's what you call a Wave Motion Gun.
    • GRBs cannot hold a candle to black hole-powered active galactic nuclei as quasars, blazars, and others alike that can pull out the energy equivalent to the combined luminosity of up to hundreds of galaxies for a much longer time that them, at the same time that they usually project two collimated jets of subatomic particles moving at relativistic speeds along the rotation axis of the black hole, which may either interact with neighboring gas clouds producing extensive star formation, or hit close galaxies presumably ruining the day of hypothetical aliens present on them. Like the former, they are among the farthest objects known.
  • While we're at it, the Soviets were also one step from launching a megawatt orbital laser, the 17F19D Skif. The initial launch, on the untested Energiya booster, carried a disarmed platform strapped from off-the-shelf parts in little more than a month; it was carried upside down,explanation and it botched the flip-over maneuver preceding the orbital insertion burn, deorbiting itself instead.
  • The so-called "Sun gun" was a theoretical weapon first proposed in 1929, consisting of a satellite in low Earth orbit that would use an array of mirrors to reflect sunlight down to the surface of the planet, burning cities and boiling seas. Later, during World War II, Those Wacky Nazis intended to build one, but it would have taken years the regime simply didn't have.

How do you like that, Obama?! I pissed on THE MOON, YOU IDIOT!
