BFG - Television Tropes & Idioms

Doom is the Trope Namer, wih the BFG-9000 appearing in all the games. It stands for "Bio-Force Gun" in the Doom movie, and "Big, uh, freakin' gun" in the Quake II manual, but the Doom design document (known among fans as the Doom Bible) specifically names it as "Big Fucking Gun."
Quake had the BFG10K in II, and the BFG in III.
- In Quake IV it was named "Dark Matter Gun", but functioned almost identically to the Quake II BFG.
- The Quake III BFG was very different from previous incarnations, being essentially a rapid-fire rocket launcher. Much fun can be had with a BFG-only deathmatch.
A mod for Unreal Tournament 2003 took the Q3 BFG to its logical extreme with the "OMFG Gun" — a 30-round rocket launcher with a fire rate of 30 rounds per second. Oh My Friggin'/Fuckin' God indeed.
- The Unreal Tournament series also features the Redeemer, literally a shoulder-mounted nuclear warhead launcher. Launching this puppy in a clearing full of enemies is one of the best ways to get a MONSTER KILL or HOLY SHIT.
  - And then someone went and modded the OMFG Gun into UT 2004.
Crysis has the TAC Launcher, a thermonuclear grenade launcher. Unfortunately it's an event item in the single player campaign which means you can't even use it until a certain scene (in which before that one, it would've been more useful). But in multiplayer (and you can cheat to get it in single player), it has similar, devastating effects to the Redeemer.
- The expansion pack introduces the PAC Cannon which you can freely use (bonus points for infinite ammo), but you only acquire it some 2 minutes before the end of the game...
- You can get the TAC Launcher via cheats, but it's very underwhelming. It's as if the effect guys (Crowning Moment Of Awesome) forgot to tell the stat guys (Powerup Letdown) that it's a freakin' nuclear freakin' weapon!
Tomb Raider 3 has the rocket launcher, an extremely powerful weapon collected about halfway through the game. There is a very small amount of ammo for it in the entire game (and that's if you explore almost everything), so the player must use it very, very wisely. Since most enemies are too weak for the gun to be used on them and only a couple of the bosses are vulnerable to weapons (although it is very effective in those instances), the rocket launcher is Too Awesome To Use.
Every game in the Grand Theft Auto features one of these, which can, against all the laws of physics, can be fired by the player while standing still. And yet the player characters are supposed to be average humans. "Average human" goes out the window the first time your character gets flung out of a windshield and stands up without a scratch.
- Not quite true, GTAIV had relatively modest weapons (Rocket Launcher not withstanding).
Vulcan Raven of Metal Gear Solid. His codename is based on the fact that he wields an M61 Vulcan gatling gun◊. A normal Vulcan gun is 188 cm in height and weighs 112 kg, and he not only hefts the gun but also its ammunition: an ammo drum the size of a refrigerator. In Metal Gear Solid 2, we have Fortune, also known as Lady Luck, who carries a rather large railgun. Her motion actor said that the dummy gun she had to point around was so big and heavy she 'had bruises all over [her] body' from handling it. It was made of wood and cardboard — one can only imagine the weight of the real thing. To top it off, Colonel Volgin wields a Davy Crockett miniature nuclear warhead in the third game, even though he only uses it once in a cutscene.
- In the fourth game, Snake finally gets his own hands on one after defeating Crying Wolf, which is the one Fortune has on MGS2 and was given to Wolf by Vamp, which can take down almost anything in one shot. Snake can also purchase a Barrett M82A2, a semi-automatic bullpup version of the famous M82A1 Anti-material rifle that can take down just about anything. It can kill five to ten lined-up enemies in one shot, it can take down a helicopter in two, and kill Gekko in one, so long as you aim for the neck.
Parasite Eve 2 allows the small-framed heroine, Aya Brea, to pick up a shoulder-mounted railgun in New Game Plus — it's as long as she is tall, made from solid metal, takes several seconds to charge, and the recoil sends her skidding back several feet each time she fires it.
The OICW from Eternal Darkness is the best gun when it comes to tearing apart Eldritch Abomination monsters.
A full-sized rocket launcher pops up repeatedly in the Resident Evil series, often used to defeat a particularly indestructible monster towards the end, and later obtained in an "infinite ammo" variant in the New Game Plus. Resident Evil 2 upped the ante by adding an infinite-ammo Gatling gun to the arsenal.
- Resident Evil 5 ups the ante even further by having two BFGs exclusive to boss fights: when fighting Excella you use a laser satellite tracker similar to the Hammer of Dawn of Gears of War fame; and of course the traditional RPG finisher on Wesker in the final boss fight, and of course since this is a co-op based game, Wesker gets TWO rocket launchers to the face. With a quick-time event and everything.
The Ratchet And Clank series, where nearly every gun (and there are a lot of them) is at least half the size of the protagonist. As they upgrade, they soon match the name on the firepower scale, too.
- This didn't stop them from making a big fraggin' gun so big and fraggin', that it actually warranted a new acronym: the Rip You a New One. What's more, the RYNO was only the first in a series of four guns (RYNO, RYNO II, RYN 3 O/RYNOCERATOR, and RYNO IV/RYNO 4-EVER). Mind you, the last one never past the blueprint stade because it was deemed too powerful. This coming from a company that created a portable black hole launcher and Colony Dropping handguns.
- Also, let's not forget the Harbinger/Supernova from Ratchet: Deadlocked. Apparently Dreadzone, the evil game show the eponymous hero gets kidnapped by, felt that the RYNO guns were too sissy, and design a gun that calls Frickin Laser Beams down from space like it's the damn wrath of god, and can be upgraded 99 TIMES.
  - And you have yet to see the RYNO V, best described as two interlocked gigantic gatling guns along with a huge ass missile launcher in the middle. This thing is the friggin Cosmic Horror of weaponry, three times bigger than the character that use it.
  - To sum it up: Ratchet is the new god of Engineers. "Use more gun", indeed.
KOS-MOS in Xenosaga wields a number of BFGs, notably a triple-barreled tri-gatling gun (that's three sets of three barrels each — and it's her weakest special weapon).
- And she dual wields them.
- Some would point out that KOS-MOS is, in and of herself, a BFG.
Chris Stone in Freedom Fighters can wield a Kalashnikov PK-74 machinegun like a normal assault rifle.
Final Fantasy X-2's Gippal has a Big Fragging Pink Gun. With a sawblade on the end.
Breath Of Fire III 's resident Gadgeteer Genius, Momo, uses this as her weapon.
Zone Of The Enders 2 has the Vector Cannon, huge even by the standards of most of its Humongous Mecha and forcing the protagonist's Super Prototype mech Jehuty to actually land before it can be charged and fired.
Serious Sam has a minigun almost as long as Sam is tall and a man-portable cannon firing explosive DU cannonballs. The ability of Sam to use either while running and jumping has led to suggestions that he be "upgraded" from Badass Normal to Charles Atlas Superpower-user.
- In the second game, the above-mentioned cannon is so large Sam actually rides it while it's equipped.
The Turok series is known for its big bad guns. Some of the more notable examples include the Quad Rocket Launcher, Fusion Cannon, and Chronoscepter from the first game, the Scorpion Launcher and Nuke from the second game, and the PSG (Portable Singularity Generator) from the third game.
Makai Kingdom allows you to equip your forces with Gatling Guns, Bazookas, or Flamethrowers.
Rozalin from Disgaea 2 utilizes a Gatling gun in one of her special attacks.
Sasha, the Heavy Weapons Guy's primary gun in Team Fortress 2, which weighs 150 kg and fires up to 2,400 $200 rounds per minute. And its sister, Natascha.
Gauntlet: Dark Legacy's Archer had a Turbo-attack that, while not strictly speaking a gun, was the biggest, most complicated automatic repeating quadruple crossbow ever seen. And that includes Van Helsing!
- And Gauntlet: Legends did the Archer one better by making her fully-charged special a huge cannon. The narrator's voice calling the attack actually named it B.F.G.
Maya Schrödinger in Wild ARMs 3 has a gatling gun hidden up her skirt. She wriggles her hips and it just falls out.
The Super Scope item in Super Smash Bros Melee and Brawl can be charged up for quite the shot given the opportunity, and the Cracker Launcher from Brawl can be aimed for firecracker shooting fun. And then there are the Dark Cannons used by the Subspace Emissary bad guys, that automatically turns any Smash fighter into a trophy!
- Samus's fully-charged Arm Cannon possibly counts, and if not her Final Smash definitely does. There's also a BFG on the Halberd stage, as well as one featured in Subspace Emissary that takes down said battleship in one shot.
The agents of Syndicate Wars (and to a lesser degree Syndicate) have a whole arsenal of BFGs, including miniguns, pulse lasers, plasma lances, graviton guns and nuclear grenades. They need upgrades to their skeletons to wield them effectively.
- The Gauss Gun from the original Syndicate definitely counts. It's a rocket launcher that can fire a rocket, instantly, across half the map and will kill nearly anyone in one hit (or destroy cars, etc). Also tends to set things on fire a lot. Pity they didn't keep any of these around for the sequel...
  - Thought that too, until I experienced the almighty power that is Satellite Rain.
The Spartan Laser in Halo 3 is a huge shoulder-mounted anti-tank beam weapon. One shot can burn straight through three Warthogs lined up back-to-back. Not to mention tanks, enemy dropships...
- Also from Halo, the Fuel Rod Gun fires green, highly explosive energy that can deal very severe damage, has a five round clip, and can fire pretty freakin' fast for something that powerful.
- Spartans (and Elites) can also wield gigantic Tri barreled minigun from the hip. This is a weapon that is about as long as the average UNSC Marine is tall.
  - The "AIE-486H Heavy Machine Gun" (the minigun) only uses 7.62x51mm SLAP(Sabot Light Armor Piercing) ammunition.
- Let's not forget the fact that all UNSC capital ships are "built around a gun,"-that being a giant Magnetic Aceleration Cannon (MAC gun). It fires multi-ton slugs at a fraction of the speed of light; things it hits tend to go away. Puny Humans may not have the technology of their adversaries, but they definitely have more firepower.
Super Robot Wars has so many BF Gs it's almost impossible to list them all. Some of the most noteable are the SRX's HTB cannon, R-Gun ITSELF, any of the Macross battleships main gun, Wing Gundam Zerp's twin buster rifle, the Huckabein's black hole gun, DX Gundam's Twin sattilite cannon, F-type Evangelon unit 1's N2 launcher and Impact bolt. The most nefarious of them is the Ideon gun in SRW Alpha 3, which is probably the most powerful gun on this list, as it frys a huge part of the galaxy in front of it. It has huge damage, and the map attack version can annailate the whole map, AND kill the final boss and his army IN TWO SHOTS.
Done with a twist in the System Shock games. In the first game, the strongest energy weapon is the LG-XX Plasma Rifle, which fires refracting orbs of plasma that leave glowing marks where they ricochet. In the second game, the Fusion Cannon takes the title, taking up 1/3 of your view and firing huge green balls of death. The problem with both weapons? You're more likely to kill yourself than your enemies, especially in cramped quarters, and more conventional weapons prove to be more useful in later stages of the games.
The Fallout series features a slew of BFGs, even getting their own skill set for use. They range from the mundane Bazooka to laser Gatling guns and plasma rifles. The third instalment has the "Fat Man", essentially a handheld nuclear catapult. Since There Is No Kill Like Over Kill, there is a unique Fat Man that fires eight mini nukes at once. Can kill anything with one shot, but the 8 mini nukes have a combined cost of over 2000 caps.
The indie game Shadowgrounds has a few. For one, the minigun can be upgraded to have a shorter spinup time and can be placed on the ground as a sentry. For two, the rocket launcher's alt-fire is a dirty bomb. For three, the lightning gun can fry even the biggest mooks in a second.
Shadow The Hedgehog has a few of these, obviously. Most notable is the chain gun, probably the most broken weapon in the game. It gets more ammunition than any other, has the best firing rate and is one of the more powerful weapons as well. Oh, and he wields it in one hand.
Seraphim characters in Sacred 2: Fallen Angel can learn an ability called BeeEffGee which summons, well, a BeeEffGee. Its strength scales with both the character's level and the BeeEffGee ability level and is usually more powerful than other weapons you can acquire at the time, but the ability takes up one of your very limited "buff" slots. It's also available in the original.
Devil May Cry started out by giving Dante a revolver grenade launcher to play with, along with an energy shooting...thing, which covered his entire forearm. This was only a taste of the silliness that would come along later.
- Devil May Cry 2 had him tool around with a distinctly more excessive Stinger missile launcher instead of the grenade launcher.
- 3 really got into the swing of things, throwing Dante a colossal Lahti L-39 anti-tank rifle called Spiral. And let's not forget Lady's BFG, Kalina Ann: a rocket launcher with a rather large bayonet attached. It's about as big as she is, and yet she can not only lift it, but somehow whip it out in time to stick the bayonet in a wall after being dropped off a tower.
- In Devil May Cry 4, Dante sports the Pandora, a suitcase which can transform, among other things, into a bazooka, a stationary laser turret and a flying craft equipped with roughly twenty rocket launchers, all of which fire at once. Nero, meanwhile, has a carbine-sized Hand Cannon which can be powered up to fire timed-delayed high explosive bullets.
General RAAM from Gears Of War carries a fragging troika/shotgun combo for his weapon of choice in the first game!
Iji has several BFGs.
- The MPFB Devastator
- The Velocithor,
- The Plasma Cannon
- The insane Phantom Hammer, which is capable of shooting through several kilometers of rock. While they are usually mounted on space ships, the final boss carries one of these.
- The Massacre is the grand king of BFGs. How powerful is the Massacre? This powerful.◊
The first Max Payne game, near the end, gives you a Pancor Jackhammer, which is an fully-automatic shotgun that the PlayerCharacter still fires semi-auto. This is because it can kill any Mook you can see in one shot. Combined with the slightly less powerful Colt Commando, the bulk of the last level basically consists of running up a staircase and occasionally stopping to shoot.
Planescape Torment features a level 8 spell, ''Mechanus Cannon'. Casting it fires a giant energy cannon on the plane of Mechanus, with the blast passing through a portal to strike your target.
Jak II: Renegade. Near the end, you power up A GUN THE SIZE OF A SKYSCRAPER to punch a hole in the Metal Head nest.
- In Jak 3, there's a gun actually had to be shrunk so Tess could hold it.
StarCraft has a gauss rifle designed to be fired while wearing Power Armor.
Star Wars: Empire at War and its expansion. The original didn't really have any (besides the Death Star and planetary turbolasers), but the expansion was rife with them. First, besides the Death Star II and planetary turbolasers, there's the Aggressor-class Destroyer that has, not one, but TWO: A giant freaking Ion Cannon and a giant freaking Plasma Cannon that can take out enemy ships and hardpoints in one shot. Then there's the MZ-8 Pulse Cannon, basically a treaded tank built around a superzised BFG 9000. Zann Consortium space stations also get a giant plasma gun starting at Level 3. Then there's the quad tri-barrel Mass Driver cannons of the Vengeance-class Frigate.
Marvel Vs Capcom. Say it with me... PROTON CANNON!!!
Monster Hunter has a couple of different classes of BFG-like weaponry. Heavy Bowguns are technically supposed to be crossbows, except that they're about as long as the wielder is tall, clip-fed, and capable of launching cluster bombs. In a similar vein, Gunlances are essentially a one-handed gauntlet with a cannon - yes, a human-sized cannon - mounted on it, and a bayonet mounted on that. The Gunlance is actually more of a melee weapon, although it does have some ranged attack capability, but come on - it is what it is.
Harman Smith of Killer7 wields a Barrett M82 anti-material rifle, which he holds aloft from his wheelchair. Keep in mind that such guns weigh about 13kg and are used to destroy lightly armoured targets, but have recoil mechanism that allow it to be fired from the shoulder.
The Coffin in Gungrave, which the main character carries strapped to his back, can transform into either a heavy machine gun/gatling gun, a bazooka, and a missile launcher. Grave can also smack the bad guys with it as a melee attack.
Ciel in Tsukihime wields the Seventh Scripture, a harpoon gun that fires holy scriptures designed to prevent reincarnation and also kill things. She weighs around 90 pounds, the Scripture weighs around 130. And that's without all the optional bits added on, which can double the weight. Yea, a gun that weighs 250+ pounds carried by a 90 pound girl. It doesn't seem to slow her down much except in Melty Blood during a sub boss fight so she's actually still possible to beat.
The Conduit has two. The SMAW rocket launcher technically qualifies as a BFG due to its size, while the Carbonizer Mk16 is a big, flashy, high-tech Energy Weapon that cooks enemies in seconds.
In Lost Planet: Extreme Condition, most VS weapons can be used on foot. Gatling gun? Check. Massive shotgun? Check. Four barrel homing laser? Check. Insanely large rocket launcher? Check.
Wolfenstein (the 2009 game) has the Leichenfaust 44, a Nazi superweapon powered by extradimensional energies. It fires large globules of said energy that cancel out gravity within their area of effect and reduce enemies to piles of scorched bones.
In possibly the first ever example of a man-portable firearm in The Legend Of Zelda series, Twilight Princess introduces us to Auru and his weapon of choice - a shoulder-fired mini-cannon that shoots bombs.
Uncharted2 lets Nathan Drake walk around with a GAU-19 .50 calibre rotary gun. It's the most powerful weapon short of explosives, but suffers from accuracy issues and weight. Still a lot of fun to use.
The John Woo game Stranglehold has two of thse — the M-249 machine gun for those who prefer More Dakka, and the Rocket Launcher for those who prefer to BLOW THINGS UP. Both of them can be used to devastating effect with the Tequila Bomb Barrage attack, and using the latter weapon with Barrage is the best way to take out the helicopter miniboss in the final stage.
The Contact Beam in Dead Space is powerful enough to vapourize any non-boss Necromorph with one hit. It's meant to blast through dense rock strata. It's also probably meant to vapourize pirates too.
Speed Buster's Buster Launcher from No More Heroes, just look at the thing.
If the Discworld ballista mentioned below qualifies as a BFG, so does the crossbow wielded by Regulus in the game Demigod. When loaded it's as long as he is tall.
Mass Effect 2 gives the player access to an entire range of BFG-tier guns, known appropriately enough as "Heavy Weapons." These include a miniature nuclear missile launcher, and the Blackstorm Projector, which is quite simply a portable black hole cannon.

AC/DC's song, "Big Gun". If you can't hear the lyrics, the chorus goes a little something like this:

Big gun, got a hot one Big gun, got a number one Big gun, loaded and cocked Big gun, hot hot hot Got big gun, ready or not Big gun, give it, give it a shot

A number of weapons from Ghost in the Shell Stand Alone Complex, including Saitou's sniper rifle, Batou's Gatling-type gun, and Ishikawa's glue-bullet capture gun. Of course, considering that they are all cyborged to various extents, it makes some sense that they can wield these weapons. Togusa, the only non-cyborg, just uses a Mateba autorevolver. In the original movie Batou also uses a man-portable HEAT SPIW (High-Explosive Anti-Tank Special-Purpose Individual Weapon), which he affectionately calls "your standard-issue Big Gun".
In at least one occasion on the classic cyberpunk anime Bubblegum Crisis, (entirely human) police officer Leon McNichol makes use of a massive anti-mecha gun that appears to be some sort of miniaturized cannon. Again seen in the episode "Red Eyes" when Linna is equipped with a prototype motoslave connected to a huge cannon capable of not only reaching but vaporizing a Kill Sat in orbit. And somewhat humorously presented in Revenge Road where the ADP has to deal with a rampaging super-car that seems to have taken on a digital mind of its own. Their response is to drag out a decommissioned tank so as to have a gun capable of stopping it.
The weapon of choice for the Capital Police in Jin-Roh: The Wolf Brigade is a hand-held version of the MG-42 heavy machine gun from WWII. In real life, this weapon weighed well over 11 kg and was only accurate with a tripod, and was normally used by a team of two to four men. However, in the movie, they take steps to make the use of a man-portable one seem more realistic, such as an added foregrip and a shoulder-mounted compartment that holds the ammo-belt. The weight-balance problem was more than likely evened out by the heavy armor they wore. Plus, they always seemed to use them at ranges of only 10-15 feet from the target, and at such a close range, accuracy problems for a heavy machine gun become essentially non-existent, since the spray fire is going to kill everything.
In Hellsing, Seras Victoria, a recently turned vampire, uses a 30mm cannon that weighs 120 pounds unloaded. Her strength enables her to wield it like a mundane personal rifle, much to the shock of the human troops. And this is one of the smaller guns in the series.
Natsuki Kruger in Mai-Otome is a proud wielder of a BFG from Hammer Space (literal, in-story Hammer Space, accessed via Applied Phlebotinum). It is at least 1.5 times as long as she is tall◊, if not longer.
There's also the experimental laser rifle Kaneda gets a hold of in Akira, when it's shown that Tetsuo can halt ordinary bullets in midair.
Trigun thrives on this trope. Wolfwood wields the Cross Punisher, which actually contains a machine gun, a missile launchers, and (in the anime) between six and eight normal-sized guns. Knowing that Wolfwood's Punisher is slightly taller than him and that Wolfwood is about 1.85m, the weapon must weigh at the very least 100 kilos, which makes it a more than honourable BFG (and Wolfie one honourable Badass). Millie also has a machine gun than must weigh more than her. Kain the Longshot, one of the Gung-Ho Guns, has a sniper rifle with what appears to be a thirty foot long barrel. It is highly accurate until Vash uses his Improbable Aiming Skills to put a bullet square down the barrel from a kilometer away.
- Not to mention Vash and Knives' Angel Arms.
Traditional Magical Girl shows usually have the heroine wielding a cute little magic wand. In Magical Girl Lyrical Nanoha, the heroine's weapon of choice is a long magical staff that turns into a BFG capable of firing Wave Motion Gun-class blasts of energy.
- The third season later introduces us to the Numbers Cyborg Dieci. Her weapon is called Enormous Cannon, which is just what it sounds like.
Bolt Crank's affectation for comedically over-sized armaments of all shapes and sizes amounts to half the appeal of Eat-Man.
Gundam OVA The 08th MS Team had one of these. Imagine Seras Victoria's Artillery piece, scaled up to be used by a humongous mecha.
- In the original series (and later spin-offs), many of the normal Mobile Suit troops often carried giant 250mm+ Bazookas. According to the series' backstory, these were originally used to launch nuclear warheads.
On the subject of Gundam, there's also the infamous Buster Rifle from Gundam Wing. It's a beam cannon that kills space colonies, but only has fuel for three shots. Halfway through the series, it gets upgraded to an even MORE powerful version that can be fired as many times as Heero wants. There's also the colossal Gatling wielded by Gundam Heavyarms, which is later upgraded into two Gatlings side by side. And then in Endless Waltz, it's got a double Gatling in each hand (supplied with Hammerspace bullets.) That's just excessive.
- And even then, the power of the Satellite Cannon in Gundam X completely dwarfs the guns in Wing.
Sakuya of Koi Koi 7 can call forth any gun at any time, and has a preference for BFGs.
Hitomi Landsknecht from ICE wields one, with a gorgeous Steam Punk design.
Miyu from the Mai-Otome manga has a tri-barrelled triple gatling that is almost certainly a Xenosaga Shout Out. Unfortunately, the enemies she attempts to use it on have Deflector Shields...
Chachamaru of Mahou Sensei Negima at one point wields a gun as long as she is tall. It's powerful enough to temporarily contain an uber-powerful demon.
America's ultimate weapon in Getter Robo Hien is a BFG, made by transforming the Statue of Liberty into a laser cannon which is then wielded by one of their Humongous Mecha.
Bleach - 2nd Division's Captain, Soifon, an expert in assassinations and melee combat, truly dislikes her Bankai. Why? Because it's a freakin' cannon◊. And it makes an insanely giant boom.
Cowboy Bebop - The plasma cannon mounted on Spike's red hot rod spacecraft.
Tengen Toppa Gurren Lagann: Yoko's enormous sniper rifle. The gun is about as long as she is tall, and is capable of taking down Humongous Mecha, occasionally in one shot.
Scryed: George Tatsunami's Alter, Big Magnum, is, as its name would suggest, a Big Fucking Revolver that shoots Big Fucking Bullets.
The Law Of Ueki: Any one-star or above Celestial being, most notably Robert and Ueki has a weapon called Kurogane, which turns their arm into a giant, 6-foot cannon that completely overshadows the user in size.
Though not actually that big, Lady Eboshi's gun in Princess Mononoke is the prototype of a BFG especially designed to be used by women. It's a shoulder-fired matchlock musket which fires shot well over an inch in diameter and has a really big muzzle flash. With it Eboshi mortally wounds two very powerful forest spirits and decapitates The Great Forest Spirit with a single shot.
Eboshi: "Now watch closely, everyone. I'm going to show you how to kill a god."
Many of Gao Gai Gar's predecessors in the Brave series had their ultimate forms come equipped with BFGs (while the former went down a different route). Two of the most famous (and most appropriately named) are Fire J-Decker's Max Cannon Mode and Great Might Gaine's Perfect Cannon.
In Transformers: Victory, Deathsaurus has the Living-Metal-Destroying Cannon.
At one point, Lt. Surge has a bazooka. What makes it awesome is its ammo...which are Voltorb and Eletrode. Seriously.
Death the Kid wields two of these when using Death Cannon, which are somehow merged with his arms. They're usually normal-looking pistols.

The M134 Minigun carried by Jesse "The Body" Ventura's character in the movie Predator, lovingly nicknamed "Old Painless." In reality, the weapon is mounted to attack helicopters.
The Terminator smiles over an identical minigun in T2? John Connor notes, "Oh, yeah. It's definitely you." On set, Schwarzenegger was the only person on the set that could physically carry the minigun by himself.
First subverted, and later used straight, in Men In Black, when Agent J (Will Smith) asks for a really powerful gun, and Agent K (Tommy Lee Jones) gives him the Noisy Cricket — an incredibly tiny gun which turns out to be incredibly powerful, with enough recoil to knock J across the room. Towards the end, however, they both get some really big guns.
- In the Animated Series J eventually acquires a suppressor for the Noisy Cricket that reduces the recoil to where he can fire it without bowling himself over each time.
One of the more divisive (between Rule Of Cool and Video Game Movies Suck but most certainly under Refuge In Audacity) moments in the Hitman film of the game series is when Udre Belicoff goes Guns Akimbo with two SAWs.
Played completely straight in The Matrix: Mouse, the wimpiest member of the team, similarly attempts to go Guns Akimbo with two drum-fed fully automatic shotguns. Sadly his attempt to provide More Dakka does not result in any deaths at all except his own. Although the film has "lots of guns", they're mostly the type that can be concealed under a Badass Longcoat.
Nearly all the Prawn weapons in District9 counts as BFG's.
One of the most plausible instances of this trope appears in the sci-fi film Aliens. In order to save colony survivor Newt, Ellen Ripley straps an automatic pulse rifle/grenade launcher combo to a flamethrower with duct tape, along with a belt of extra grenades, making her a one-woman army. In the extra material on the DVD, Sigourney Weaver actually carried the weapon around the set while shooting scenes, although it was ridiculously heavy, and had to be taken off at regular intervals.
- Don't forget the M56 smartguns, which Cameron had constructed from German machineguns, Kawasaki motorcycle parts, and camera harnesses.
Hellboy's latest weapon, "Big Baby" from Hellboy II: The Golden Army, is a modified shotgun with an insanely large six-shooter attachment. Deleted scenes reveal that the gun's gigantic cartridges have bottles drawn on the sides, with the message, "Suck on this" written on the shells.
Hellboy: You woke up "the baby!"
Rambo is big on this one.
General Jack D. Ripper in Doctor Strangelove kept an M1919A4 machine gun in his golf bag!
Guy Ritchie likes to turn BFGs against their owners:
- In Lock Stock And Two Smoking Barrels, one of Dog's bandits brings a Bren light machine gun to hold up the pot growers. The gun is so loud that Dog threatens to kill him if he fires it again. Ultimately a girl grabs the gun and unloads the thing on Dog's crew. In slow-motion, the shells hitting the ground sound like oil drums.
- In Snatch, Vinnie brings a giant semi-auto shotgun to hold up a bookie. Sol remarks, "It's a fucking anti-aircraft gun!" Vinnie uses it to blow a hole in the wall and force the girl at the counter to lower the protective shield, but she ultimately snatches it and fires on the thieves before making her exit.
The Doom movie, where it's lampshaded by being called the "Bio-Force Gun." Of course, when The Rock's character gazes in awe at it before acquiring it, he says to himself, "Big fucking gun..."
While there is no specific BFG in the movie, Split Second might have been the first to refer to them as such. "We need to get bigger guns. BIG FUCKING GUNS!" These were the "Combat Shotguns" they checked out from the police armory- in actuality a pair of miniguns that used shotgun shells instead of bullets.
The Annihilator 2000 in Beverly Hills Cop III, which is not only a highly powerful rail gun, but includes such additional features as — and none of thee are exaggerations — a cell phone, radio, CD player, and microwave oven.
In Tremors, the "Elephant Gun" used in the Rec Room. In reality, an 8 gauge side-by-side shotgun. Probably fired roughly a 2 ounce slug of hardened lead, if it was loaded for elephant. (Why wouldn't it be? You never know when you will face a war elephant.) In the sequel, there's the Grizzly Big Boar, a single shot .50 caliber rifle. Unfortunately, it was a bit too big.
- Tremors 4 goes that extra mile, featuring an 8-foot 4-inch, 94-pound punt gun with a two-inch ("A" Gauge) barrel. It was actually a prop built for the film using a triple-loaded 12-gauge inside to produce a muzzle flash; the barrel's inside was sprayed with WD40 prior to shooting to add more smoke. This is because apparently there are very few functional punt guns left in America today.
In the western Appaloosa, Viggo Mortensen's character carries a mammoth 8-gauge shotgun around with him at all times. The gun weighed 11 lbs and was 50 inches long. In reality, such shotguns were mounted to the sides of riverbarges and used to fire into large flocks of water fowl.
- The same type of gun (a punt gun) makes an appearance in Desmond Bagley's thriller The Tightrope Men. One of the protagonists recognises it for what it is, and they actually use it in the appropriate way, blasting a mook with birdshot. Comment: "What weapon did you have on that punt? A bloody flamethrower?"
In Eraser, Arnold (who else?) wields two rail-guns which can see through walls and fire bullets at near-lightspeed.
The eponymous Black Helicopter in Blue Thunder is armed with a 20mm rotary cannon. It's awesome.
In Transformers: Revenge of the Fallen, the human military gets to field a battleship-mounted railgun which puts down Devastator (who's the size of a building) in a single shot. It may have been an ignoble death for poor Devastator, but damn if it wasn't awesome.
- Nevermind the goddamn rail gun, any projectile carried by a Transformer automatically fits this trope due to being wielded by alien robots that on average are 20 feet in height. Although in particular, Ironhide, Megatron and Optimus fit this quite well.
In RoboCop the bad guys get hold of some "assault cannons" in order to take down the otherwise bulletproof cyborg hero. One of them test-fires one of the guns, blows up a car with one shot, and declares "I like it!"
Ellen Ripley gets one of these in Aliens.
In Superman returns, there was guy who's gun was so big he needed a crane thing to wield it.
In the 1997 film, The Jackal, Bruce Willis's character (The Jackal, who else?), has a custom-built BFG that he has to keep in the back of a car, controlling it remotely via a laptop. To test it, he blows off Jack Black's hand with a single shot.
Four Rooms: The Wrong Man segement... someone with a large caliber hand gun receives a phone call from another room in the hotel.
"No needles here, kid. Just a big fucking gun."
— Sigfrieg

In the Transmetropolitan series, Yelena Rossini briefly picks up one of these at a gun shop. She is acutely disappointed when she is not allowed to take it home, and asks whether it's because of her sex, but it turns out that the weapon is "designed for people with two backup spines."
The GAU Avengers used by the trolls (and Shiro) in Samurai Cat in the Real World.
- It should be emphasized here that Shiro is only a little kitten after all. Uncle Tomokato was impressed that he couldn't see the special effects lines.
In the Superman Elseworlds comic At Earth's End, Superman uses a comically oversized gun (it's twice his size!) to kill twin clones of Hitler.
In the first arc of Wildstorm's Gen 13, the newly gen-active Fairchild picks up a massive laser/rifle type weapon she obtained from one of the fallen I/O ops to brandish in her fight to save her new comrades....though it seemed to be more of just a chance to see a hot spandex wearing redhead brandish a gun considering she was now about 6'5 and superhumanly strong regardless.
Gene in Kingdom gets his hands on one when he falls in with the Wild Bunch. In his own words:
Gene likes the new kill-toy.
Don't know how we got this far without mentioning Rob Liefeld in general, and the way he drew Cable in particular. Third image from the bottom in this hilarious article:
“I think Cable should be holding a BIG gun on this cover.”
"Well yeah he usually is."
“Pffffft, no, I mean a REALLY big gun.”
In [1] Brianna is VERY fond of this trope.
"Don't worry, it's got a stun setting!
"A fifty milimeter gatling cannon with a STUN setting?!"
"Uh...Yeah.
In [[The Incredible Hulk]], a soldier in a battle mans a high-tech cannon about ten feet long. When a blast knock the weapon off its legs, pinning the soldier beneath, the Hulk (the really smart version) picks up the cannon, wields it in one hand, and to the enemy says "...let us reason together"
Sabretooth's shortlived partner Birdy was quite fond of guns which her tiny frame would normally find impossible to lift.

Itchy and Scratchy from The Simpsons have a duel where they come up with bigger and bigger guns; eventually Itchy has the good sense to actually shoot instead of getting yet another larger gun from hammerspace(his gun is already the size of planet Earth), and sends scratchy flying into the sun - improbable targeting skills at work, too!
Roadblock (and his Suspiciously Similar Substitute, Heavy Duty) from GI Joe.
- Roadblock's gun is identified in the original comics as carrying a M2 Browning machine gun, a gun that is usually operated by a squad or vehicle mounted, and weighs up to 120 lbs.
While not completely fitting with this trope (it's more of a Wave Motion Gun), the Justice League watchtower has a large laser that is quite literally called the Binary Fusion Generator. This was not unintended by the writers.
A lot of Transformers have these.
- The Requiem Blaster from Armada, which changes hands a couple times over the course of the series.
- In Robots In Disguise, Optimus Prime, Ultra Magnus, Hightower, Mega-Octane, and Rollbar had weapons which would qualify as BFGs. Optimus' was shoulder-mounted, though, and Mega-Octane had both a hand held one and a back-mounted pair of cannons.
- Ironhide's blasters in the live-action movie. According to the modelers, his guns have more pieces than some of the other Transformers in their entirety.
- Both Generation 1 and Animated Swindle have a giant gun that can mount on top of their vehicle mode.
- Megatron's fusion cannon from Generation One (and Megatron himself in at least one scene). Once he was upgraded to Galvatron, it became even more powerful - in a couple of the post-Movie episodes, it was used to destroy planets.
- The Animated Megatron also has a fusion cannon which is almost identical (if not a little bit bigger!) than the original and even uses the same sound effect.
- Meanwhile the Armada version of Megatron had a waist-mounted cannon which is so powerful it blows him backwards along the ground◊. Of course, most of the other Armada characters have similarly ludicrously powered weapons when they power up with Mini-Cons — Starscream's first test of his Null-Laser cannons leaves a huge crater.
- Rampage's Hellbelcher from Beast Wars.
- Another one is Rhinox's "Chaingun(s) of Doom,".
- And the ones on the base in this exchange:
  Megatron: (walking up to the Maximal Base, when half a dozen turrets come from out of nowhere) Ah! I come in peace!!
  Rhinox, through megaphone: (turrets fold away. twice as many turrets, three times as big unfold and point at Megatron) You'll leave in pieces.
Remember the quad-guns the Millenium Falcon had? The ones that Han and Luke used to shoot down TIE Fighters in the first Star Wars film? In StarWars: Clone Wars, a ARC Trooper carries one of those guns mounted on his chest. (See image at the top of the page.)
Almost subverted, but not quite, in the CGI-animated Action Man, when Coach gives Alex Mann a device called the BSU 10000. Alex thinks that this stands for something more sophisticated than the bazooka-like gun that it looks like at first glance, but Coach fires the gun at a pile of scrap metal (blowing it sky-high) and reveals that it really stands for "Blow Stuff Up". (Possibly a G-rated version of "Blow Shit Up", considering the show's audience.)
C.O.P.S. featured Mace, who carried a laser bazooka, and uses it in the opening to slice a hole in a reinforced concrete walkway.
- Also featured Buttons McBoomBoom who, along with having THE GREATEST NAME IN ALL OF FICTION, kept a pair of BFGs in his chest.
There's some debate among ReBoot fans as to whether Bob's guitar in the mindbendingly awesome guitar duel episode, which he refers to as a BFG, is a reference to this trope or not. The guitar is actually a Gibson BFG Les Paul, but that doesn't necessarily rule out a Doom reference.
- The unofficial ReBoot Episode Zero (a compilation of every cutscene from the PlayStation videogame) plays this a bit more straight. After Hexadecimal reveals that Dot is trapped inside one of her mirrors, Bob goes berserk. He brutally kicks Megabyte's ascii, then stares right at the mirror-slash-vidwindow above the Tor looking into Hex's lair. His next line, with progressive camera zoon-in on each letter: "Glitch: B.F.G.!". His already big gun turns into the poster child of More Dakka, then he points it straight up at the mirror, says his Catch Phrase ("Stay Frosty."), and blasts the crap out of it. (Watch the epic scene here, starting at 3:14.)

This trope even shows up on the Discworld, which is largely free of firearms, in the form of the massive 900 kg ballista siege weapon carried by Sergeant Detritus (an enormous troll made of rock) as a crossbow, "The Piecemaker." It is called this because the iron stone-piercing spear it used to fire was replaced with a bundle of arrows, which was presumably supposed to allow it to operated as an area weapon but unintentionally results in the arrows disintegrating into an expanding cone of burning wood fragments when fired, making it more like a (very inaccurate) shotgun that can blow holes through walls, doors, and presumably people.
- When the Piecemaker is first used, it uses a ballista bolt. The results were so horrifying (And probably expensive) that they just tied a bunch of bolts together instead. The results were even more horrifying.
  - The scene in Night Watch where it is fired - as a warning shot! - at an assassin is perhaps the most hilarous (and most destructive) scene in all of Discworld. Yes, this even includes the exploding cabbages.
Neal Stephenson's novel Snow Crash features "Reason,", a gatling gun firing depleted-uranium slivers at incredibly high velocities. It's a little hard to move around because its nuclear power supply, utilizing radiothermal isotopes, uses an outboard heat-disperser that drops into the ocean.
- "See, I told you they'd listen to Reason."
Neal Stephenson also features a Vickers machine gun in the World War II timeline of Cryptonomicon, which is less futuristic than Reason because of the lower-tech setting, but noteworthy because of the (characteristic) pages-long description of its badassery.
Piling up plasma cannons and other big guns in Iain M. Banks's Use of Weapons, Cheradinine Zakalwe says he'll need "FYT" weapons for a mission. His Culture handler says she doesn't recognise the term; it stands for "Fuck You Too".
Another Banks novel, Against a Dark Background has as a Mc Guffin the "lazy gun". Among other peculiarities is the fact that it weigh three times as much when it's upside down as when it's right side up. Its effect on its tend to be ... humorous ..., such as materialising a free-falling ship's anchor directly overhead, or a spear, piece of tsunami, small nuke, or asteroid. When researchers attempted to disassemble one its self-destruction took out a fifth of the city and killed half a million people.
One of The Executioner novels has Mack Bolan fighting the giant Igor Baibakov, a big and psychopathic ex-Spetsnaz terrorist who uses a Barrett Light Fifty as his weapon of choice. Not only does he use this .50 BMG monster in its primary role as a sniper weapon, but he's so big and powerful that he can use the thing at close range like an assault rifle, which is more justified by his impressive size and strength and the Rule Of Scary than anything else.
- Not to mention Mack's favourite sniper rifle, the Weatherby Mark V Rifle (.460 Magnum calibre).
Happens in the Star Wars novel Wraith Squadron, as part of a ludicrously complex plan to capture one of Zsinj's corvettes: Gamorrean (think the guys guarding Jabba's palace in Return of the Jedi, but smarter) pilot Piggy uses an X-wing laser cannon as a personal weapon. It blows clean through a floor/ceiling (and the officer above it) with one shot. Wedge even points out how implausible the weapon ought to be.
Wedge: "A laser cannon is nine meters long, Five."
Kell: "Not the essential components and housing, sir. Strip out all the computerized aiming and synchronization equipment, the diagnostics, the flashback suppressor, I think we could chop it down to a meter and a half, two meters."
In Phules Company, one of the sluglike Sinthians tries to shoot a full-auto shotgun... but since said trooper is half the body mass of a human and riding a Hover Board at the time, the resulting blast sends him into a rapid spin— fortunately Phule had the foresight to disable the "full auto" feature beforehand, so no further shots are fired and the surrounding soldiers remain unpunctured.
The Prince Roger series, by John Ringo and David Weber, features a lot of BFGs, but the giant four-armed Mardukans really take the cake. They can "off-hand" wield cannons meant to serve Humans as crewed support weapons and capable of blowing large concrete buildings and stone walls to dust. When some madman decides to equip a squad of them with a species-appropriate version of Powered Armor, the standard issue weapon that goes with it is more typically the main gun of a tank.
- Taken to the extreme by Erkum Pol, The Big Guy even by the standard of the nine-feet-tall-on-average Mardukans. He likes BFG's, and can carry the aforementioned tank gun without Powered Armor. On the other hand (one of them, anyway), his aiming skills aren't even up to Imperial Stormtrooper Marksmanship Academy standards. When he takes the tank gun along on a hostage rescue mission, Hilarity Ensues (for "hilarity" read "an entire city block being set on fire").
In John Barnes' Timeline War series, The Alliance issues its soldiers the SHAKK. It's only rifle sized... But the ammo is self propelled over a six mile range, seeks its target so aggressively it can even be fired from behind full cover using a remote camera, delivers enough kinetic energy with each round to liquify a human being, and comes in a 6000 round magazine that can be emptied in a few seconds on full-auto. Exploits include shooting down barely-visible planes and ripping modern-era tanks to scrap. The weapon can also manufacture more rounds from random trash. So... Yeah. At least in spirit, it is one very, very, very B.F.G.
The later Dale Brown books give users of the Tin Man Powered Armor the ability to wield railguns.
A more realistic depiction appears in Harry Turtledove's Hitler's War. A Czech expat fighting for the French scavenges an anti-tank rifle and spends the rest of the book wrecking light armor and blowing people in half.
"Starworld" by Harry Harrison. One of the Israeli commandoes is firing a handheld .50 calibre recoilless machine gun during the attack on Spaceconcert.
The M-300 grav rifles from John Ringo's Posleen War Series qualify, using gravity drivers to fling antimatter-loaded pellets (or, later, when supplies are low, regular uranium pellets) around at just below the speed of light.
The Guide is not very specific about its size, but it's definitely not a gun to be trifled with: "The designer of the gun had clearly not been instructed to beat about the bush. "Make it evil," he'd been told. "Make it totally clear that this gun has a right end and a wrong end. Make it totally clear to anyone standing at the wrong end that things are going badly for them. If that means sticking all sort of spikes and prongs and blackened bits all over it then so be it. This is not a gun for hanging over the fireplace or sticking in the umbrella stand, it is a gun for going out and making people miserable with."

Joyce Brown's shoulder-fired Hammer Space cannon in It's Walky!!, which is even called a BFG and is over a foot wide at the muzzle. Somewhat justified by her superhuman strength.
The "Clenk Gon" from Girl Genius, possibly seen again wielded by Klaus much later. Agatha's various death rays are also good examples.
Kore the dwarf paladin from Goblins wields a pair of eight-shaft repeating crossbows. They are quite devastating.
In this A Miracle of Science comic: And if I say no? Gun. You make a convincing argument
Frequently shows up in Narbonic (usually in the hands of Mell, the evil intern). One reader posts comments keeping up with "Big Freakin' (tm) Gun Count".
Parodied in MegaTokyo with a BFWii control.
Plasma cannons in SSDD are illegal because they have a tendency to blow up their owners and anyone around them, but that doesn't stop Tessa from owning one (guess how sane she is).
Schlock the titular character from Schlock Mercenary uses a BFG-109 Plasma Weapon complete with Ominous hum and intimidating barrel glow.

Many of the heavy weapons in Warhammer 40,000 are BFGs. It is worth noting that normal humans have to mount them on mobile platforms and use them in teams of two — it's only the superhuman Space Marines who can use them like traditional BFGs, and even then most of them have to stay still and brace themselves before firing. Of course, there are some Badass Normal humans who can lift said weapons by themselves, and those are realistically seen as abnormal.
- It is worth elaborating that the standard Space Marine weapon is a fully-automatic gun firing rocket-propelled explosive-tipped "bolt" rounds, each of which is capable of punching through most infantry armor to detonate within the target, or with sustained fire blast apart lightly-armored vehicles.
- Special mention goes to the Tau Railgun, the main armament of the Hammerhead Tank and XV 88 Heavy Crisis Suit: "The tiny munition had passed through the vehicle with such speed that everything within the hull not welded down had been sucked out through the exit hole. Including the crew." Keep in mind that the "Vehicle" is a freaking tank.
- Kaptin Badrukk has a particularly awesome example - it was taken from an Ogryn (basically an Ogre IN SPACE!) and is loaded with highly unstable plasma cylinders. Standing near it is a death sentence. Though this is less due to its firepower, and more because it's hotter than Chernobyl. (Indeed, it's statistically more likely to put Badrukk at risk of injury than it is to actually hit anyone, thanks to how the Gets Hot rule works.)
  - As the upper-mentioned Gets Hot rule got changed, it's slightly less deadly to Badrukk now(if you call dying of it each second game less deadly). Not that he got any more accurate, sadly
Paranoia had the "plasma gun". It would also occasionally malfunction, and some of those malfunctions would cause the entire thing to explode; naturally, it being Paranoia, you couldn't tell which malfunction was which, and neither could the rest of the party. And you had to strap the thing on to use it; taking it off suddenly (say, to get away from the now-it's-a-bomb strapped to your back) was not easy.
- It also had nuclear hand grenades... and the explosive radius was classified above your security clearance.
Rifts has a number of heavy weapons, from railguns to missile launchers, with a perennial favorite being Plasma Cannons. One of the most infamous is the "Boom Gun", the railgun used by the Glitter Boy Powered Armor, which is so powerful the armor has to anchor itself to the ground before firing. A different style of Glitter Boy has a gun that can only be used by it because, without its unique stabilization system, any other mecha or vehicle would eventually shake itself apart with the recoil. Another weapon of note is the ATL-1 laser cannon, which is so powerful it drains an entire energy clip for a single shot. In Russia, the troops of the warlords there are so enamored with BFGs that they actually designed and used a servo-harness to allow normal humans to carry them around.
The Proteus expansion set to the now mostly forgotten Netrunner trading card game paid homage to the concept with the 'Big Frackin' Gun' icebreaker card — a powerful 'gun' for the Runner player to use in cyberspace to blow away the Corps's virtual sentries, cheap to install but with a hefty activation cost per 'shot'.
Traveller has the PGMP (Plasma Gun, Man-Portable) and the even more OTT FGMP (Fusion Gun, Man-Portable) for when there's No Kill Like Overkill. Some models can only be used if you're wearing Powered Armour.
The Heavy Disintegrator Cannon fromGURPS: Ultra-Tech is powerful enough to vaporize a building in one shot while you sit safely in the gunners seat hundreds of miles away. Rather than the long reload times of many BFGs this one can fire ten shots a second. The most powerful kinetic weapon is the Grav Railgun which can be carried by people in Powered Armor, it "only" fires with enough force to punch through a couple tanks and then kill the target... twenty times per second.
As below in Real Life, Call of Cthulhu has the Elephant Gun. It's used a lot, I hear.
Warhammer fabtasy battles has ogre leadbelchers that wield cannons in a blunderbuss like fashion. Dwarfs and Empire also has their fair ammount of big guns but none rivals the leadbelchers of the ogres.

Tech Infantry features a wide variety of plasma and other weaponry designed to be carried by heavy-weapons troopers in Powered Armor. It greatly helps that many of those soldiers inside the armor are Werewolves.
The final entry by Invertin in this topic.
"HIS REVOLVER IS A FREAKING TANK"
- This isn't very impressive until you realize how big a tank shell is, and how large his revolver would have to be. And this is a sidearm.
Big Fucking Steam Punk Guns!

Jaffa staff weapons in Stargate SG1 are pretty big on their own, but at one point Teal'c wields a dismounted anti-ship version taken from a Death Glider.
- And one-shots an Al'kesh with it. In the windshield.
- In Stargate: Continuum, Vala has to be dissuaded from bringing this◊ (the X-699) to Ba'al's extraction ceremony.
- How have human railguns not been mentioned? Not just a regular railgun, either, an automatic railgun. They even call attention to it in Stargate Universe.
  Eli Wallace: Wow, that is a big gun.
In The Prisoner's spy spoof episode "The Girl Who Was Death", the title character Sonia, having failed to kill Number 6 with various elaborate death traps, finally decides on the direct approach, escalating from a machine gun to hand grenades and mortars before finally drawing a bazooka on him.
Kamen Rider Ryuki: Kamen Rider Zolda (Kitaoka Shuuichi) wields a gun twice as long as he is tall (picture◊), and two pretty big guns mounted on his shoulders, too. And that's nothing compared to his Macross Missile Massacre Finishing Move...
- Let's not forget Kamen Rider Faiz's Faiz Blaster. That thing was HUGE. Sad its gun form was rarely used.
- Also, for that matter, Faiz's Final Form Ride in Kamen Rider Decade is the Faiz Blaster. Of course, this time it's human sized due to being the transformation of a person. Dunno if this makes it bigger or smaller than the original though...
Combining unique individual weapons into a BFG is a near-staple of Super Sentai and Power Rangers. Of course, so is the revival/enlargement of the monster by the enemy bosses right after it's been taken out by said weapon.
- Tokusou Sentai Dekaranger (adapted into Power Rangers SPD) has a Humongous Mecha that can transform into a BFG so big it takes two or three other Humongous Mecha to wield it. (Its usual procedure is carry a Monster Of The Week into orbit, and then use its BFG mode.)
- Don't forget Power Rangers Time Force (Mirai Sentai Timeranger). The Rangers each have very oversized cannons (to Narmy effect when they're carried around in a manner that makes them seem like... well, nearly weightless props.) Individually, they're bigger than most team-wielded weapons. And they can combine into an even bigger one for finishing purposes.
- Samurai Sentai Shinkenger has ShinkenRed transform his BFS, the Rekka Daizantou, into a BFG for the finisher attack.
BFGs are the weapon of choice against Daleks in the Doctor Who episode "The Stolen Earth". The one Rose carries looks like it weighs half as much as she does, and Mickey and Jackie wield equally impressive versions. They were first used in Season 2, though, by the Preachers.
- Jack Harkness, of both Doctor Who and Torchwood has always been fond of them. His weapon of choice is a modified defabricator that is the size of a minigun.
- The Special Weapons Dalek in the old-Who episode "Remembrance of the Daleks" was basically a self-propelled BFG that first blew down a large metal gate before taking out an entire rival Dalek squad. And they say its gun is fifty times more powerful than the normal Dalek gun. There's a reason the other Daleks called it "the Abomination".
Harper in the Sharpe series of novels and television dramas carries a Nock Volley Gun.
Where would this article be without Jayne of Firefly, who never left Serenity without enough firepower to take out a ship?
- Hey! She has a name, you know.
In Star Trek: First Contact, Worf takes a REALLY BIG gun, shouts "Assimilate this!", and blasts a group of Borg into oblivion.
In the Buffy episode "Innocence", the gang has to defeat an enemy called the Judge who "no weapon forged" could kill. However, that declaration was made before Christ, and humanity has much bigger weapons. Buffy decimates him with an anti-tank gun.
Although the Cylon Centurions in the new Battlestar Galactica have built-in automatic weapons, Cylon boarding parties can be seen hand-carrying heavy machine guns in "Razor" and "Daybreak".

Real life example, which ultimately is just about as impractical as the fictional ones: 76mm High Impulse Weapon System Remember to keep 80% of your weight on your front foot!
In WWII a Soviet soldier, Sgt. Antipkin, was documented to carry an enormous PTRS antitank rifle — a monster gun weighing 20 kg, about two meters long, and served by a crew of two at best — all by himself, as if it was an ordinary hunting rifle. He also used it to shoot down German planes — while standing. The guy was a veritable giant, though.
Who can forget the Barrett M82A1 Anti-Material rifle? Shoots a machine gun round, and can disable parked aircraft and light armoured vehicles. Did we mention that, according to Metal Gear Solid 4, it's endorsed by Hideo Kojima?
- Some M82s were modified to serve as Cobra Assault Cannons in Robo Cop.
- Its successor is the M107 Barrett: unlike this pistol the manufacturer went to great lengths to keep the recoil controllable.
Less known but even more powerful: the South African Mechem NTW-20 shooting either 14.5mm armor-piercing ammunition or 20mm (!) high explosive, fragmentation or incendiary shells. Depending on the version it weighs 29 or 26 kg. And yes, that's the one from Halo.
- For scale, consider that the sniper rifle in Halo was based off of this one, and it's still a pretty sizable weapon when used by a powered armor.
Also in the 20mm camp: the Croatian RT-20, which is a recoilless cannon, firing the massive 20mm Hispano-Suiza antiaircraft gun round.
Speaking of dual M-249s...
At the battle of Qala-i-Janghi in 2001, the SBS soldiers detached their general-purpose machine guns from their land rovers. They were later shown on the news firing from the hip.
The M-388 Davy Crockett tactical nuke, and the aforementioned M134 minigun, all of which are actual weapons, though the M134 is normally mounted on aircraft rather than carried by infantry. Attempts to produce man-portable rotary weapons have been made as well, though none have entered production.
The Beo Wulf .50 Caliber Assault Rifle as seen on the Future Weapons TV show.
Recoiless Rifles are man portable artillery pieces that have shoulder fired, tripod mounted, or vehicle mounted versions. One version, the Carl Gustav, is still in use today.
And then there's the Nerf N-Strike Vulcan EBF-25, which uses the power of six D batteries to launch darts from a plastic belt at a staggering rate of...about three darts per second. May not seem like much compared to real weapons (or paintball, or airsoft...), but if this thing had better range it would pretty much be the BFG of Nerfing.
- There do exist Nerf guns with far more firepower than that. Most notable is the gun with 20 darts, and two fire settings. One setting is fully-automatic fire...and that's the slow one. If you prefer, it can just launch all 20 darts at once.
- Wouldn't a better name be the Nerf Heavy Bolter?
- Meanwhle, the Super Soaker equivalent is the Monster XL, a double-barrelled monstrosity with a range of up to 41 feet, capacity of 3500 milliliters of water (or your liquid of choice) and six settings for each barrel. Takes a hell of a lot of pumps to get up to pressure though...
From WWII-era Finland comes the Lahti L39 20mm anti-tank rifle. The weapon was so large (it weighed 50 kilograms) that Finnish troops nicknamed it the Norsupyssy ("Elephant Gun"). It was even used as a sniper rifle. A fully-automatic version was used as an anti-aircraft weapon.
The Dillon Gatling Gun. Nobody has quite figured out how to fit it into a shoulder holster, yet.
The Barrett M109 Anti-Material Payload Rifle is, other than one-off prototypes, the closest you're going to get to the Harkonnen Cannon. An M82A1 scaled up to accept 25mm ammunition, the M109 is currently capable of penetrating 1.5 inches of rolled homogeneous armor at 1200 meters. Long-term optimizations are projected to result in a rifle that can penetrate greater than 2 inches of high-hardness armor at up to 2000 meters.
The Nock Volley Gun: 7 .52 caliber barrels fired together. It frequently broke the shoulder of the shooter.
The AA12 Shotgun: looks like a tommygun, but fires 12 - gage shotgun shells and microgrenade rounds.
The .700 Nitro Express.
- Topping even that is the .950 JDJ. It is based on a 20mm Vulcan cannon case, shortened and necked up to accept the half-pound bullet. Most rifles chambered for it weight about 100lbs, and the recoil will still probably break the shoulder of anyone who fires it standing. It is probably the most powerful rifle cartridge in the world.
Elephant guns (Fun Fact: in WW 1, soldiers would use elephant guns against tanks since they were the only guns that could pierce the tanks armor)
The KS-23. It's a 4-gauge (.92 inches, or 23mm, hence the name) pump-action weapon with a three-round magazine made from lathed-down rejected barrels for ZSU antiaircraft guns. There's some debate over whether it's a shotgun or a carbine, though it certainly better resembles the former; it can fire buckshot, riot rounds, or steel-core rounds that can go through the engine of a truck. At over 100 metres.
But if you want to get really big in shotguns, you need a punt gun. These colossal guns were designed to be anchored to the centreline of a boat and aimed by rotating the whole thing in the water, and could take out an entire flock of birds in one shot. An A-Gauge punt gun could have a barrel diameter of over two inches and throw well over a pound of shot into the air each time it fired.
