History Main / SwissArmyGun

* 2012's ''Film/{{Dredd}}'' features the same Lawgiver as ''Film/JudgeDredd'' below, with its trademark [[CallingYourAttacks voice-selectable ammunition]].

* ''Series/BlakesSeven'' featured some of these for the last season when they started going more overtly CyberPunk. Quite how one makes a relatively small handgun fire [[SlowLaser Slow Lasers]], [[StunGuns unspecified less-lethals]], [[KineticWeaponsAreJustBetter "old-fashioned percussion bullets"]] and [[InformedAbility a bunch of other stuff they never get around to using]] ''just by swapping magazines'' was glossed over.

** Other countries have experienced with the same or similar concept as well, such as the Australian AICW (Advanced Individual Combat Weapon), the South Korean Daewoo K11 DAW (Dual-barrel Air-burst Weapon) and the Chinese QTS-11. However, most if not all of them fall victim to the same drawbacks as the XM29, namely weight and cost.

* The Beretta ARX160 is designed to be easily and rapidly customizable. It's grenade launcher can be quickly detached and replaced with a bipod and it's barrel can be swapped out in seconds. This allows it to conceivably go from an assault carbine to a light machine gun or a marksmen's rifle during a fire fight if someone had the need and parts.

* Crossfire was a combination gun (both rifle and shotgun), expected to be universally handy weapon, suitable for any circumstance. It was introduced in 1988 as semi-auto .308/12ga weapon, but actual producion guns became pump-action and 5.56mm/12ga. Turned out that they are too expensive, unreliable and very uncomfortable to use.

* Activision had the game ''videoGame/{{Apocalypse}}'' starring Bruce Willis. Willis was scientist Trey Kincaid, a master with nanotechnology who used his technologies to develop a weapon that was a humble machine gun, but with the proper ammunition could become a laser, particle beam or various explosive weapons.

* Similar to the guns in ''Literature/OldMansWar'', Jeffrey Thomas's novel ''Blue War'' had the Assault Engine. Assault Engines are a combination shotgun, carbine, grenade launcher and energy beam projector to deal with any threat in the jungles of an other dimensional Vietnam-expy.

* Similarly, in Jefferey Thomas's ''Blue War'' that's part of the ''Punktown'' setting, humanity brings Assault Engines to an other-dimensional war similar to the US-Vietnam War. Assault Engines can fire energy bolts, high-calibre bullets, flechettes and grenades.

* VideoGame/JazzJackrabbit's long blue gun, the LFG-2000 Blaster, is designed to be compatible with most types of ammunition, conventional or otherwise. This includes plasma rounds, rubber bullets, freezing rounds, small homing missiles, large exploding rockets, flamethrower fuel, pepper spray, electric charges, even standard TNT.
* ''HardReset'' has not one but ''two'' {{Swiss Army Gun}}s. One of them acts as a [[MoreDakka chaingun]]/[[GatlingGood gatling]] [[JackOfAllStats assault rifle]], a ShortRangeShotgun, a GrenadeLauncher, a [[StuffBlowingUp rocket/missile launcher]] and a minelayer. The other shoots bolts of energy, [[LightningGun a stream of energy]], [[BuffySpeak zappy electrical field grenade things]], a high-power pinpoint-accurate sniper mode with shots that penetrate walls, and explosive [[EnergyBall energy bolts]] that 'phase' through cover to find your target. Oh, and each mode has a SecondaryFire too.
* In ''VideoGame/PerfectDark'', nearly every weapon in the game has a secondary function, some of which are quite unique. Eg. the Laptop Gun (SMG and automatic sentry), Dragon (assault rifle and proximity mine), K7 Avenger (assault rifle and threat detector), RCP-120 (SMG and cloaking device), etc.
* ''VideoGame/SaintsRowIV'': The "'Merica" gun. As its description says, it's "a dozen guns, a rocket launcher, and a flamethrower, all wrapped together behind one convenient trigger." [[SoundtrackDissonance Complete with patriotic music playing whenever it's held.]]
* In Videogame/StarWarsTheOldRepublic the Republic Trooper class (no matter the Advanced Class choice) has this as a weapon. It can fire regular shots, an "explosive round", fire mortars, lay down a close AOE Ion Pulse, and can [[HealingShiv heal teammates]].
* ''VideoGame/ParasiteEve'' featured a weapons customization feature that allowed you to take 'features' from other weapons and put them on whatever weapon you wanted. A NewGamePlus weapon might be a pistol capable of firing exploding bullets [[MoreDakka in three round bursts with shotgun-like spread]]. [[VideoGame/ParasiteEve2 The sequel]] featured a more realistic version of this, the [=M4A1=], which can accept any number of modifications ranging from rather benign attachments such as a bayonet or a magazine attachment to double the ammo count per-magazine, to the really fantastic stuff like an underbarrel armor-piercing laser or high-power paralyzing taser.
* The Playstation FPS ''Codename: Tenka'' (or "Lifeforce Tenka" overseas) featured the "Self-Generating Polymorphic Armoury" or SG-26, an assault-rifle-sized weapons system that could shoot standard lead, lasers, grenades, missiles and mines, some of them upgradeable with various sub-modes (like dual and chargeable laser beams, and automatic rifle fire).
* Pandora from ''VideoGame/DevilMayCry4'' is a demonic briefcase which is able to change its configuration and is apparently bottomless. It can be transformed into a [[GatlingGood gatling gun]], an [[FuumaShuriken oversized three-bladed shuriken]], at least two types of rocket launchers of various efficacy, a [[WaveMotionGun big laser cannon]] and a floating platform [[MoreDakka laden with]] [[MacrossMissileMassacre rocket launchers]]. Overall, this briefcase has [[NumberOfTheBeast 666]] forms, but we get to see [[TakeOurWordForIt only the ones described above]] and the last-resort one, ''[=PF666=]: Omen'', which is activated by simply [[SealedEvilInACan opening up its lid]].
* In ''Videogame/BattleZone1998'', the astronaut's automatic plasma rifle can be shouldered to use an integrated [[SnipingTheCockpit cockpit-penetrating sniper rifle]]. In the sequel, the Pulse Rifle used by ISDF has the same functionality, with the addition of a telescoping barrel and a more ergonomic digital scope that pops up from the rear of the receiver. The sequel also has a 'Bazooka' alternate weapon, which can fire (relatively) rapid-fired rockets, or a massive high explosive blast.
* ''Videogame/GunmanChronicles'' is made of this trope. It has little more than 6 actual weapons, but each weapon has at least 4 submodes, that can even have their own ''sub-sobmodes'': you can program a Rocket Launcher for firing homing or non homing missles, and sub-program said missles to be high explosive, grapeshot, or attach to the surface as laserwire high explosive/grapeshot mines.
* In ''Videogame/HardReset'', the player is only given two weapons from the start - the C.L.N. Firearm and the N.R.G. Weapon. However, these two weapons transform. The C.L.N. Firearm can shift into ballistic and explosive weaponry such as a standard machinegun, a shotgun, a grenade launcher, RPG launcher, and a mine thrower. Likewise, the N.R.G. weapon can shift into energy-based, and electric weaponry such as a plasma rifle. shock blaster, electric mortar, energy railgun, and a ''smartgun'' that fires homing projectiles. However, the entirety of the weapons do not transform, only the muzzles, or barrels do.
* In ''Videogame/{{Overwatch}}'', Widowmaker's rifle functions as a sniper rifle when using the scope or a machine gun when hip-firing.
* In ''VideoGame/DonkeyKongCountry2DiddysKongQuest'', King/Kaptain K.Rool arms himself with a blunderbuss that while looking rather plain and ordinary, is able to rapid-fire massive cannonballs along with various types of debilitating gases that hinder the Kongs' ability to dodge his attacks. He's also able to use it as a jet to propel himself around the arena at high speeds and as a vacuum to draw the Kongs close so he can [[PistolWhip club them with its stock]]. The last function ends up working against him as clogging it up with a cannonball will cause it to backfire explosively.
** The king wields the same blunderbuss in his appearance in ''[[VideoGame/SuperSmashBros Super Smash Bros. Ultimate]]'', where it retains its multi-purpose nature, being able to fire cannonballs as well as vacuum up both enemy projectiles and opponents for use as ammunition.
* Your character in ''VideoGame/NoMansSky'' only has a single Multi-Tool. Instead of acquiring new guns, you install modules into your Multi-Tool that weaponize it in different ways, such as a Boltcaster that turns it into an automatic gun, a Blaze Javelin that charges over a couple seconds and uses carbon as ammo, or a Plasma Spitter that functions as a grenade launcher. The Multi-Tool also accepts non-combat modules, such as the Mining Beam or the Terrain Manipulator, as well as non-offensive modules such as a force shield. You start with a small Multi-Tool with limited capacity for modules, and as you progress through the game, you can replace it with larger Multi-Tools that can accept more modules as well as more upgrades.
* Throughout the ''VideoGame/BlazBlue'' series, Noel Vermillion's Nox Nyctores Bolverk has taken on the form of a pair of [[HandCannon Hand Cannons]], a minigun, a rocket launcher, a shotgun and a {{BFG}} that fires a massive laser beam at the opponent, to name a few.
* Activision had the game ''Apocalypse'' starring Bruce Willis. Willis was scientist Trey Kincaid, a master with nanotechnology who used his technologies to develop a weapon that was a humble machine gun, but with the proper ammunition could become a laser, particle beam or various explosive weapons.
* The Service Weapon in ''VideoGame/{{Control}}'' is less an actual gun and more gun-ness manifest, taking on the shape of any gun its user envisions with [[BottomlessMagazines unlimited ammo]]. For Jesse, it can be a revolver, a shotgun, a submachine gun, a borderline sniper rifle, and a grenade launcher. According to the lore, it's closer to a SwissArmyWeapon, [[spoiler:theorized to have been fabled weapons like Excalibur and Mjolnir]], but that never appears in the game.
* 10tons's ''Jydge'' features a character who's a mashup of ComicBook/JudgeDredd and Film/{{Robocop}}. So it's fitting that its gun, the Gavel [=Mk1=] is the unholy offspring of a futuristic lever-action carbine, the [=FN SCAR=] and a steel sledgehammer. This makes it a gun that's awfully good at smashing skulls. The Gavel [=Mk1=] has different firing modes that not only turns it to a shotgun or assault rifle, etc. with unlimited ammo (but still needs reloading), but also lets it fire lasers, plasma and ion bolts as well. The Gavel [=Mk1=] can add a special weapon that lets it fire a limited number of rockets or [[StarfishRobot spider drones]] and other things. It can also house up to 3 different mods giving the gun abilities such as recovering health from killing and giving your gun better rapid-fire. The only drawback to the Gavel is that it can only switch out its settings when not on a mission.
* Captain Deadbeard from ''VideoGame/PlantsVsZombiesGardenWarfare 2'' has a ShortRangeShotgun that shifts into a SniperRifle whenever his crosshair is zoomed in.

[[folder:WebAnimation]]

[[folder:WesternAnimation]]

* Exaggerated in the ''WesternAnimation/AdventureTime'' episode "Varmints", where Princess Bubblegum uses a strange shotgun with a knob that adjusts between many bizarre firing modes: [[SlowLaser Slow Lasers]], [[TransformationRay projectiles that turn things into flashlight batteries]], force fields, and creating a ''second'' gun of the same kind that starts out fused at the barrel to the first one.

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

* Daisuke's gun from ''Anime/HeatGuyJ'' may count. The gun itself only has one particularly notable feature, a retractable hook at the bottom of the grip used for close combat. However, it can use a variety of ammo, including standard bullets, [[spoiler:presumably]] a silver bullet, explosive Red Tab bullets, and electric Blue Tab bullets that stun those they hit.
* A one-shot character in ''Anime/KirbyRightBackAtYa'' wields a machine gun/sword/flamethrower.

[[folder:ComicBooks]]
* ComicBook/JudgeDredd's Lawgiver, which has specific rounds for basically any given situation.

* ''ComicBook/{{Nightwing}}'' villain Torque was given a assault rifle supplied by Intergang that had various voice-activated functions. It could do laser blasts, explosive blasts, an optics flare for blinding people and a kinetic pulse-type feature that could push something away. When Torque goes overboard and the gun starts overheating, it gets another function: as a bomb.

[[folder:{{Fanfiction}}]]

[[folder:{{Film}}]]
* Zorg on ''Film/TheFifthElement'' has developed one, and gives a very helpful [[Film/JamesBond Q Speech]] on its features, in this quote:
--> ''[[GunPorn Voila, the ZF-1]]. It's light; handle's adjustable for easy carrying, [[RightHandedLeftHandedGuns good for righties and lefties]]; [[IKEAWeaponry breaks down into four parts]], undetectable by X-ray, ideal for quick discreet interventions. A word on firepower. Titanium recharger, [[BottomlessMagazines 3000-round clip]] with bursts of 3 to [[MoreDakka 300]], and with the Replay button (another Zorg invention) it's even easier. One shot... ''(shoots training dummy)'' ...and Replay [[RoboTeching sends every following shot to the same location]]. ''(demonstrates by spraying bullets at the Mangalore warriors; the bullets arc back to the training dummy)'' And to finish the job, all the Zorg oldies but goldies. [[StuffBlowingUp Rocket launcher]]... [[AutomaticCrossbows arrow launcher]] [[TrickArrow (with exploding or poisonous gas heads)]], very practical... our famous [[NetGun net launcher]]... [[FireBreathingWeapon the always-efficient flamethrower]], my favorite... and for the grand finale, the all-new '[[FreezeRay Ice-cube System]]'''. [[labelnote:*]]The [[SchmuckBait unmentioned]] last feature? [[SelfDestructMechanism self-destruct]].[[/labelnote]]

* Similar to the above example, 2012's ''Film/{{Dredd}}'' features the same Lawgiver, with its trademark [[CallingYourAttacks voice-selectable ammunition]].
* ''Film/InvitationToHell'' has the main character helping to develop a suit meant for an expedition to Venus, which comes with a retractable gun in [[NothingUpMySleeve its sleeve]] that [[EnergyWeapon shoots laser beams]] and can also act as a [[FireBreathingWeapon flamethrower]].
* In ''Film/{{Blastfighter}}'', Pete gives Tiger an untraceable high-tech shotgun. It has an interchangeable rifle barrel, can fire rifle grenades (including tear gas), and comes with a variety of ammo, including, high explosive, incendiary, and amour-piercing. Needless to say, all of its functions get a workout during Tiger's LastStand.

[[folder:{{Literature}}]]
* In "Literature/TheSoftWeapon", a 1967 story by Creator/LarryNiven, the titular weapon includes a wide variety of functions. It is also a MorphWeapon.
* The dial-a-gun or "dallygun" from Creator/GordonRDickson's 1970 SF war novel ''Literature/TacticsOfMistake''. It wasn't very practical for the harsh combat environment, as dirt could jam it and it required that lots of different ammunition and spare parts be available, but the protagonist used it once to great effect.
* The rifle used by CDF troops in Creator/JohnScalzi's ''Literature/OldMansWar''. It can shoot bullets, grenades, flames, microwaves, rockets... Even better, one can customize to fire, say, a blast of flame followed by a grenade. The "ammunition" is a block of nano-machines which assemble into the correct type of ammunition upon firing.
* The Memory Sword in ''Literature/TheDarkSideOfTheSun'' by Creator/TerryPratchett can become a wide variety of weapons, from swords to molecular strippers to projectile guns that make ice bullets by freezing atmospheric moisture.
* Colonel Fedmahn Kassad's FORCE-issue rifle in the ''Literature/HyperionCantos'' includes flechette grenades, laser beams, and several other weapons in one package.
-->It was designed to do everything but cook the troops' food, and with its energy weapon component on its lowest setting, it could probably do that too.

* David Gunn's ''Death's Head'' series has protagonist Sven Tveskog's SIG-37, a HandCannon with a true A.I. that can select various ammo types for Sven, aid in targetting enemies and fire a built-in PlasmaCannon for harder targets. The SIG will also offer conversation, tactical advice and whatnot. It also freaked out when it was given a poor paint job.

* Literature/TheRisenEmpire had its military armed with variaguns. These guns could use a variety of ammo for its ballistic hardware and also had a built-in RayGun that could stun or kill depending on setting.

* In 1980s post-apocalypse men's adventure series C.A.D.S, the titular [[PowerArmour C.A.D.S armour]] has 9mm machine guns, e-ball launchers and liquid plastic flamethrowers. The 2nd generation C.A.D.S armour changes the 9mm machine guns to cannons that can vary their calibres to shoot anything from small pistol rounds to mortar shells.

[[folder:LiveActionTV]]

* ''Series/LevelUp'': Wyatt's Blast-A-Ton is gigantic swiss army gun with lots of ammo and many types of ammo.
* Even at the most limited definition (things that could be the same basic effect to different degrees counts as one mode, and modes that ''could'' be used as weapons but aren't are discounted), Franchise/StarTrek's phasers have at least two attack modes: shoot at things to make them stunned/killed/disintegrated[[note]]disintegration is ''probably'' a separate function, but the stun/kill settings are implied more than once to be a matter of the strength of the attack more than any fundamental difference in what it does -- high stuns can kill, and low kills can sometimes be survived even by mundane [[PunyEarthlings humans]][[/note]], and blow up.

* ''Series/JuukouBFighter'' (and it's American adaptation, ''[[Series/{{Beetleborgs}} Big Bad Beetleborgs]]'') had the Input Magnum (in ''Beetleborgs'', the Sonic Laser), a laser gun that, depending on the 3-digit code inputted on the bright blue keypad on one side, would fire different beams or effects. The sequel, ''Series/BFighterKabuto'' (or ''Beetleborgs Metallix'') had the Input Card Gun (Data Laser in the US), where different Input Cards would be slid into the back for different effects.
* ''Series/{{Battlestar Galactica|2003}}''. Pilots are equipped with standard sidearm with a large-calibre underbarrel attachment for explosive rounds that can make Centurions' [[YourHeadAsplode heads explode]]. Presumably it also fires specialist loads like signal flares for downed pilots.
** This may be based off vierlings like the [[http://en.wikipedia.org/wiki/TP-82 Space Gun]], a combination sawed-off rifle/double-barreled shotgun designed as a compact foraging tool, since different game animals are easier to hunt with shot or bullets.

[[folder:TabletopGames]]

* In ''TabletopGame/{{Paranoia}}'', cone rifles and some other guns take multiple types of ammo (armor-piercing, hallucinogenic gas, etc.) with the same size shells, which are [[SarcasmMode never ever mislabeled]].
** And some of those mislabeled cone shells ''definitely'' wouldn't have a chance of being [[NukeEm tactical nuclear devices]].
* ''Tabletopgame/BattleTech'''s Mauser 960 Assault System, the standard issue rifle of the Star League, was a laser rifle with an integrated grenade launcher, a [[VibroWeapon vibro]] [[BayonetYa bayonet]], and an enormous survival kit (flares, emergency nutrient pills, a radio, a spade, and a medical kit) built into the stock. Few exist in the modern age, most of which are in horrible shape save for a sizable stockpile of pristine ones in [[ChurchMilitant ComStar's]] vaults. Like the real life OICW, it was an enormously heavy design that rapidly fatigued its users; and the Clan retrofit is even heavier.
* You have to be superhumanly strong to use most of them, but ''Naruni: Wave 2'' for ''TabletopGame/{{Rifts}}'' contains a series of mercenary multi-rifles, which tend to combine three weapons in one, such as the Silverfire, which contains a gun which fires silver projectiles, a flamethrower, and a laser; and others that combine plasma cartridge, laser, plasma beam, grenade, micromissiles etc. together, usually in combinations of three. Some can even have a vibro-bayonet mounted, for extra cost.
** The Daisho-10 made by the Oni in the [[SpaceOpera Three Galaxies]] setting is a nonomachine-based weapon that transforms between a Sub-machine gun and a Vibro-sword. The company that produces it also has a version reserved for its own use that has a fully-functional third form of a camera or hand-held computer.
* If you like the idea of using [[Film/TheFifthElement Zorg brand weapon clusters]] in your OGL science fiction games, there is a blatant copy in the OGL supplement ''1001 Science Fiction Weapons''. You will need to be proficient in both energy and slugthrower weapons to use the General Weapon System Mark 183, which contains a shotgun, particle beam, laser, micromissiles, and grenade launcher in one single handy pod. The more advanced Mark 490 contains an X-ray laser, stun ray, plasma gun, armour-piercing force bolt, and an antimatter gun.

* The Remco System 7 toy gun from the 1980s. Spinny-disk shooter, periscope, decoder, parachute launcher, ring key lock, secret compartment, and a lot of pure awesome.

[[folder:VideoGames]]
* Samus's ArmCannon from ''Franchise/{{Metroid}}'' certainly qualifies. It has been, among other things, a rocket launcher, grappling hook, freeze beam, shotgun laser, heat ray, and a recharge plug. The list just keeps growing with more games.
* VideoGame/MegaManClassic's iconic [[ArmCannon Mega Buster]] changes into the weapon of any Robot Master he defeats. In any one game, the Buster can function as a rocket launcher, flamethrower, ice gun, grappling wire, boomerang thrower, needle gun, and time manipulation device...just to name a few.

* The SICW in ''Classified: The Sentinel Crisis'' is a transforming machine gun/sniper rifle/shotgun/grenade launcher/gatling gun/rocket launcher. It's supposed to be man-portable, although the person carrying it ''is'' wearing powered armor.
* The canceled ''[[VideoGame/CommandAndConquer Tiberium]]'' FPS would have included a transforming weapon as part of its basic design. Wielded solely by the player, the "GD-10" served as a basic assault rifle, grenade launcher, missile launcher, and ''personal ion cannon''.
* In ''VideoGame/CityOfHeroes'', The eponymous weapon from the Assault Rifle powerset seems to do everything but dispense mixed drinks.
** Specifically: semi-auto rifle, shotgun slug, shotgun buckshot, grenade launcher, beanbag, sniper rifle, flamethrower, fully automatic rifle and missile launcher.
* ''VideoGame/StarWarsRepublicCommando'' cuts down the amount of equipment the characters have to carry by making the primary weapon modular, capable of swapping between automatic, sniper and grenade modes depending on which quick-change barrel assembly is currently attatched.
* ''VideoGame/{{Redline}}'' features such a weapon wielded by the protagonist. Besides the standard assault rifle mode, it can also become a [[ChainsawGood buzzsaw]] (with optional nitro upgrade that makes you fly around for a limited time), a rocket launcher, an EMP device (handy for those vehicles!), a shotgun, a grenade launcher, an alien goo shooter, a sniper rifle, and a {{hitscan}} plasma beam weapon.
** Creator/{{Accolade}}'s earlier TPS[=/=]FPS ''Eradicator'' also outfitted all three characters with Swiss Army Guns. In both games, to use the extra gun modes, you just collect the required ammo scattered throughout the levels-no need to collect prerequisite guns first!

* The obscure ''Videogame/GunmanChronicles'' is made of this trope. It has little more than 6 actual weapons, but each weapon has at least 4 submodes, that can even have their own ''sub-sobmodes'': you can program a Rocket Launcher for firing homing or non homing missles, and sub-program said missles to be high explosive, grapeshot, or attach to the surface as laserwire high explosive/grapeshot mines.

* Crossfire was a combination gun (oth rifle and shotgun), expected to be universally handy weapon, suitable for any circumstance. It was introduced in 1988 as semi-auto .308/12ga weapon, but actual producion guns became pump-acion and 5.56mm/12ga. Turned out that they are too expensive, unreliable and very uncomfortable to use.

[[/folder]]

* Shotguns have an equally impressive variety of specialist ammunition; less-lethal ammunition like beanbags or rubber buckshot, a round that works like a one-use miniature taser, distress flares... There's even the Dragon's Breath round, which basically turns your shotgun into a mini-flamethrower.[[note]][[AwesomeButImpractical And probably ruins the barrel after a few rounds.]][[/note]]

* In ''Literature/LogansRun'', the Sandman guns had six [[TrickBullet attack methods]]: homer (a heat-seeking projectile), tangler (sticky net), [[KillItWithFire nitro]], vapor ([[AgonyBeam ignites every pain nerve in the body]]), ripper, and needler. In the movie there were no such settings.

* ''Film/InvitationToHell'' has the main character helping to develop a suit meant for an expedition to Venus, which comes with a retractable gun in [[NothingUpMySleeve its sleeve]] that [[FrickingLaserBeams shoots laser beams]] and can also act as a [[FireBreathingWeapon flamethrower]].

* ''Series/BlakesSeven'' featured some of these for the last season when they started going more overtly CyberPunk. Quite how one makes a relatively small handgun fire FrickinLaserBeams, [[StunGuns unspecified less-lethals]], [[KineticWeaponsAreJustBetter "old-fashioned percussion bullets"]] and [[InformedAbility a bunch of other stuff they never get around to using]] ''just by swapping magazines'' was glossed over.

* Exaggerated in the ''WesternAnimation/AdventureTime'' episode "Varmints", where Princess Bubblegum uses a strange shotgun with a knob that adjusts between many bizarre firing modes: FrickinLaserBeams, [[TransformationRay projectiles that turn things into flashlight batteries]], force fields, and creating a ''second'' gun of the same kind that starts out fused at the barrel to the first one.

* ''VideoGame/{{Redline}}'' features such a weapon wielded by the protagonist. Besides the standard assault rifle mode, it can also become a [[ChainsawGood buzzsaw]] (with optional nitro upgrade that makes you fly around for a limited time), a rocket launcher, an EMP device (handy for those vehicles!), a shotgun, a grenade launcher, an alien goo shooter, a sniper rifle, and a HitScan type plasma beam weapon.

* In ''Film/BeverlyHillsCopIII'', Serge's "Survival Boutique" sells [[{{Trope2000}} the Annihilator 2000]], a combination minigun, microwave oven, rocket launcher, portable TV, flamethrower, beverage cooler...

* ''VideoGame/{{Iji}}'''s personal favorite nanoweapon, a Tasen Gen2 Preloader, can form everything from a simple shotgun to a spray fire energy weapon to a giant laser to a repulsor to a [[NukeEm nuke]]. Perhaps noteworthy in that the player must [[HollywoodHacking trick]] the Swiss Army Gun into being able to utilize many of the more unusual configurations.
* In ''VideoGame/JakIIRenegade'', the Morph Gun starts out as a shotgun, but gets mods that not only increase its normal stats, but also turn it into a single-shot rifle, a machinegun, and a BFG. The third game adds a ReflectingLaser, a Ground-wave generator, a LightningGun, an Anti-Gravity generator, a Grenade Launcher, a Drone Launcher, a Homing Needle Gun, and a Pocket Nuke.

* The SICW in ''ClassifiedTheSentinelCrisis'' is a transforming machine gun/sniper rifle/shotgun/grenade launcher/gatling gun/rocket launcher. It's supposed to be man-portable, although the person carrying it ''is'' wearing powered armor.

[[folder: WebAnimation]]

** The tabletop game has rules for combi-weapons, basically a weapon with a different weapon attached and can be used once per game.

* In the ''Franhcise/MassEffect[=/=]VideoGame/CommandAndConquerTiberianSeries'' crossover ''Fanfic/{{Renegade}}'', the Global Defense Initiative has developed "Shapeshifter" weapons using mass effect technology, which consist of infantry rifles that feature various heavy weapon add-ons. This is following GDI's [[MoreDakka standard]] [[{{BFG}} design]] [[BiggerIsBetter logic]] when applied to the lighter, collapsible weapons that can be created using mass effect technology; after all, if they can make their guns ''smaller'' and fold out into full-sized weapons, then they can fit multiple weapons into the same space and weight that a conventional gunpowder weapon possesses.
