"It was too big to be called a sword. Massive, thick, heavy, and far too rough. Indeed, it was a heap of raw iron."
- One of the combatants in the Tournament Arc of Battle Angel Alita: Last Order wields a "sword" that's big enough to need its own propulsion system and features its own energy weapon, making this a Big Fuckin' Gunsword. The combatant himself also counts — his legs have been replaced with blades and he attacks by launching himself like a shuriken. It's justified when he mentions his preferred opponents are warships.
- Berserk:
- Guts and his 6ft long, 400lb Dragon Slayer are a classic example. The story behind the Dragon Slayer is an interesting one — the blacksmith who made it was commissioned to make a sword that could kill dragons in one stroke. But since dragons did not exist (at the time), he forged a sword too large and heavy for humans to wield, because the only way to kill an impossible creature is with an equally impossible weapon. The only reason Guts can swing it around at all, let alone as skillfully as he does, is that he's been training with oversized swords since childhood: he began with a normal-sized longsword, which was much too big for him when he was six years old, and simply scaled up the size of his weapon as he grew up. The Dragon Slayer is simply the logical conclusion of this progression, but unfortunately the Dragon Slayer hasn't yet lived up to its name when comes to dragon slaying aside from cover art
◊. Ironically, despite a painstaking attempt to portray the weapon somewhat realistically with a lot of momentum and almost no real cutting edge, author Kentaro Miura has admitted in interviews that he originally hit upon the idea of the huge sword just as a gimmick to attract readers. - The portrayal of the Dragon Slayer's weight extends to the Dreamcast video game based on the series, as it's nigh-impossible to swing the Dragon Slayer in tight corridors without it bouncing off the wall to little effect (and in the manga, Serpico tried to fight a duel with Guts in a tight space precisely to exploit this flaw). In the next licensed game for PS2, set in the Millennium Falcon arc, this simply isn't an issue — most of the action takes place outdoors, while the few indoor or underground areas that Guts goes into are spacious enough to allow him to use the Dragon Slayer to full asskicking effect.
- Many other characters have large versions of non-sword weapons as well, such as an atlatl-style spear thrower that generates cannon-like force or, in a Downplaying an Indian-style flexible sword that is of normal length but has far more blades than normal (based on a real Indian weapon known as an urumi).
- Many of the Apostles wield massive weapons while in human form, but they have superhuman strength because their true forms are enormous monsters.

- In Black Clover Asta's first sword is a huge claymore nearly as long as he is tall. He also gets a second one later on; more along the lines of a proper longsword, but still quite large. Aside from having slightly different (but still Anti-Magic) powers, the longsword is useful in situations when the larger sword's size makes it too unwieldy. His third sword can remove effects caused by spells and even negate Reincarnation magic.
- Black★Rock Shooter has plently of small-to-average ladies with ridiculously massive weapons, optimal range be damned, but the most recognizable one is Black Gold Saw's signature weapon, the King Saw. It is a massive scimitar-like blade with a serrated false edge, and a similarly serrated bladed handguard in its now-most common depiction. Even when taking her horns into account, the thing is still around as long as she is tall, and similarly to Ginjo below, she is quite tall.
- Kuroki, one of the operatives in Blazer Drive wields a sword that looks suspiciously like Allan's.
- And now it's a Whip Sword like Renji's and Hibana's.
- Bleach:
- All Captain and many Vice-Captain level Soul Reapers would possess swords the size of skyscrapers if they didn't seal their power when not using it, and control their power even when using it. When transformed, some Soul Reapers gain tremendously huge weapons as a result, especially in Bankai. Tite Kubo has stated that Soul Reapers don't feel the weight of their zanpakutō because it is part of their soul.
- Ichigo's sword Zangetsu is huge even in its most basic form because he cannot properly seal his power. As a result, the sword's baseline size generates surprise among Soul Reapers who first see it. When he releases his power, his Zanpakutō unusually shrinks in size as he gains greater control. As his power develops, Zangetsu's base form shrinks in size, but still remains unusually large.
- Renji's sword Zabimaru can transform into a large extendable serrated whip-blade. In its Bankai form, Sōō Zabimaru, it becomes an incredibly large version that can demolish entire sections of Seireitei with a single swing.
- Komamura's Bankai transforms into a giant samurai wielding an equally giant sword.
- Ikkaku's Bankai Ryūmon Hōzukimaru transforms into a giant weapon with three chain-linked blades that seem like huge, modified monk's spades and guandaos.
- Several Vizards have oversized weapons in the form of an unnaturally large spear for Lisa, a giant club for Love and a giant serrated saw blade for Hiyori.
- Shinsō, Gin's Zanpakutō looks like a short knife in its sealed form, extends to the length "of a hundred swords" (roughly 60 to 70 meters or 197 to 230 feet) in the first release and grows to a whooping thirteen kilometers (or eight miles) in Bankai. However, it remains slim thorough all the extensions.
- Kenpachi Zaraki's sword Nozarashi is almost as long as a tall man in base form because he's the only Soul Reaper apart from Ichigo who cannot properly seal his sword. When the sword is in its true Shikai form, it becomes a giant cleaver roughly twice the size of his own (very large) body.
- Arrancar, being Hollows that also possess Zanpakutō, can also end up with huge weapons when they transform into their true forms.
- Baraggan Louisenbairrn has Arrogante, a Big Effing Axe. When he releases his power, the axe grows even larger.
- Harribel's sword Tiburón is a giant blade in the shape of a shark's tooth.
- Nnoitra wields Santa Teresa, a giant half-moon axe-scythe hybrid. When his power releases, his weapon transforms into six large scythes that he wields one-handed (one in each of his six hands).
- Ginjō's cross pendant transforms into a giant longsword that's almost as tall as he is. He's very tall himself.
- All Captain and many Vice-Captain level Soul Reapers would possess swords the size of skyscrapers if they didn't seal their power when not using it, and control their power even when using it. When transformed, some Soul Reapers gain tremendously huge weapons as a result, especially in Bankai. Tite Kubo has stated that Soul Reapers don't feel the weight of their zanpakutō because it is part of their soul.
- In Brave10, Saizo has one, the Mari Blade. He later has it reforged after too much damage in the finale. Date Masamune and Sanada Nobuyuki also sport massive swords in the few scenes they get to show them off.
- A subversion from Cardcaptor Sakura: The sword wielded by Syaoran looks to be more-or-less realistically sized, but because Syaoran is just a little boy, it looks huge in his hands.
- A Certain Magical Index:
- Fiamma of the Right is able to produce a Flaming Sword that is 30-40 km long.
- Kanzaki has one as well though "Shichiten Shichitou" (Seven Heavens, Seven Swords) is "only" a 2m long katana.
- Acqua of the Back wields Ascalon, which is roughly 3.5 meters long and weighs roughly 441 pounds, beating out even Guts' Dragon Slayer. It was even created under similar circumstances, with the maker fashioning based off the legend of Ascalon killing a dragon and calculating for the measurements a sword would realistically need to be at to be able to kill a dragon about 50 feet long. Deconstructed when Acqua is eventually Brought Down to Normal. He's forced to abandon Ascalon because he can't pick it up without the Super-Strength of a Saint.
- The Knight Leader wields Hrunting, the sword Beowulf used, which is roughly 3.9 meters long yet weighs as much as a regular sword. Hrunting shrinks down to 80 cm when not powered up.
- The Di-Swords from Chaos;Head are giant swords wielded by the six main girls of the show. In addition to being very large, they also glow, feed off emotions, and are invisible to everyone except other Gigalomaniacs.
- Father Remington from Chrono Crusade carries a crucifix-laser-broadsword that is taller than him. he gets over maneuverability issues by simply letting the sword tip slice through the ground during a sword swing.
- The warriors in Claymore wield, well, claymores, which are really just replicas of the historic Scottish swords that are longer and thicker. They aren't extravagantly large for BFS standards (though still nothing to sneeze at; they're typically three inches longer than the wielder is tall), but they seem to be realistically proportionate for the female warriors who wield them, who are half-demon anyway and are able to wield them single-handed, something that ordinary humans can't do. That, and the blades are indestructible.
- Post-time skip Raki has also entered the ring, as he wields a humongous sword of his own.
- The Galahad Knightmare Frame from Code Geass, personal ride of Knight of One Bismarck Waldstein, possesses a sword so huge that the sheath needs its own propulsion system. Bismarck himself also wields a human-scaled replica, which is still pretty over-sized. But then again, so is Bismarck.
- Tohka has one in Date A Live. During her Roaring Rampage of Revenge in the first novel(third anime episode), it grows to 10 meters long.
- Hibana "The Punishment" Daidara from Deadman Wonderland has a BFS Whip Sword that no one else can pick up. Pretty impressive for an eight-year-old Creepy Child.
- The Shining Trapezohedron of Demonbane looks unweildy but it has the ability to cut through dimensions and seal away powerful gods.
- Allen Walker and the Earl of Millennium from D.Gray-Man have matching (yin-yang) swords that resemble giant cricket bats. Lavi's weapon is a hammer that can become huge.
- Susanoomon from Digimon Frontier has what is, proportionally, the biggest effing blade ever with his "Zero ARMS: Orochi" weapon. He creates what looks like a BFG that's bigger than he is (which is made even bigger by the fact that he's probably more than 20 feet tall; there may be no "proportionally" about it) that creates a Laser Blade big enough to bisect the entire Digital World whenever it is swung. When purged of all the armor pieces made from his components, it reveals KaiserGreymon's sword (see below), albeit without the crest at the base of the blade.
- Most other blades belonging to individual Digimon are very large, if not quite to the same degree as that of Susanoomon. Memorable examples include Imperialdramon Paladin Mode, KaiserGreymon, ShineGreymon, VictoryGreymon, and most of Shoutmon's Xrossed forms. Digimon World 4 is a game more or less devoted to taking several famous Digimon and giving them BFSs.
- Minervamon and Mervamon both use greatswords as big as them. Minervamon even wields hers one-handed.
- Mervamon's Wide Hi-Vision Sword, a sword as wide as she is tall and three times as long.
- Brioche Dalkian of the Biscotti Republic Omitsu Squad is shown to have one in the second season of Dog Days. It's difficult to estimate the size of it as we never see all of it on screen at once. The best estimate of it size come from Lupine God Void Fang standing tall behind a line of hills, about a mile over them. Then she attacks with it.
- Eat-Man has a few of these, though The Boer Sword deserves a special mention. Despite the fact that it's only ever used in one hand the thing's easily twice the size of anyone who uses it, dangles a mass of apparently self-motivating cables, and commands the allegiance of an army of monsters.
- Gretel in Fairy Musketeers has the Missing Grave, a giant Sword with flowers growing on it. It can only be used because she wears a pair of Oven Mitts that give her strength like an Ogre. The sword is taller than most of the cast.
- Fairy Tail:
- Erza has Multiple BFSes in her possession.
- Pantherlily's sword, Bustermarm is four times his size (and he's a big guy most of the time).
- Gajeel's Karma God: Demon Blade is so huge it's comparable to buildings.
- The Musica sword found by Pantherlily can become one at will.
- At one point, a couple of mooks in Fist of the North Star team up to swing a giant sword against their opponent. Being Fist of the North Star mooks, the mookiest mooks in mookdom, they are easily bloodily killed one panel later in a Subversion of this trope.
- Full Metal Panic! gives us monomolecular cutters for use by 10-meter-tall mechas — swords with a chainsaw-like edge. Mao is shown to even have a holster for one. Although the first season only shows that one instance, The Second Raid has Clouseau owning Savages with a similarly sized scimitar.
- Being a shonen centered on fighting, Gamaran has a modest number of BFS users, usually with a proper justification, and tend to be focused on One-Hit Kill tactics. These include:
- The Ichinose clan (including Zenmaru and Kai) wields the Sadanaga blades, referred to as "Kaitou" (Beast Sword/Mystery Sword), which are large, heavy nodachi with no crossguards designed for an aggressive battle style. Both Zenmaru and Kai are shown to be rather proficient only because they both trained with it since childhood.
- Shingo Mido of the Four Divine Spears wields the "Onidachi" (Demon Splitter), a 4 meters long x 48 pounds spear. He trained so much that he can be very efficient with that.
- Ryuho Kibe the Silver Ogre wields a weapon which he calls "Colossal Steel Sword", but is actually a very large kanabo. Thanks to the Juugan battle drug he can wield the whole beast with one hand. Two other members of his squad use oversized swords in combat, heavy enough to crack the earth on impact.
- Minor character Ginji Tatehara carries around a "Mystery Sword" called Kasumi Shirosada, which is a nodachi with a thinner-than-usual blade, which makes it faster.
- Inverted with Arimaru: her sword is normal sized, but her shield (which is vital to her fighting style) is enormous.
- Sequel Series Gamaran Shura features Shiba Hien as Iori's Starter Villain and first major opponent belonging to the Shogunate's best 100 warriors: Hien took over by force the secrets of the Genba Ryuu of Nodachijutsu and wields a precious zanbato called "Monohoshizao Masamune". Unlike the Sadanaga, this sword resemble a normal katana but the wrapped maki hilt extends beyond the tsuba, which lets him wield the sword even in close combat with deadly effect.
- Again in Shura, assassin Raio Magami wields a massive Whip Sword called Shiva, which has a rather broad and long blade but is extremely thin, being an urumi and all.
- Two of the members of the Genkai Tenpei note have oversized weapons: Homare, a bona fide Action Girl and Amazonian Beauty can use a massive spanish sword known as "Montante" to mow down her opponents, while the sinister Genra wields a massive iron oar as his weapon of choice.
- After using the Goldion Hammer (not a BFS, so much as a Big Friggen Hammer) during the original series run, GaoGaiGar gets to use the Goldion Crusher — a hammer of light made out of battleships — during the OVA.
- And yet, when the main villain of the OVA Pulls out a regal-looking mech-sized blade, GaoGaiGar counters with a green crystal version of Gai's "Will Knife", just scaled up to GaoGaiGar size.
- Surprisingly enough, it's a Super Robot known as Ganbarugar in Genki Bakuhatsu Ganbaruger that had one of these and played it pretty realistically in its use. The sword is huge, but because of that it's really hard to accurately swing it at a moving opponent, so the mecha has to paralyse the enemy first.
- Housen in Gintama fights with an umbrella, like all Yato. Since Housen is also The Night King, it's a freakin' huge umbrella.
- Defied in Goblin Slayer, as the main character is dead set against using longswords because they're unwieldy in the caverns and tunnels where goblins live (and we see one New Meat character die precisely because his sword is too long to swing in a goblin cave and he knocks it right out of his hand). Note that the series has a Guts stand-in with a large sword who's seen fighting in the open to great effect. But the titular main character, as the name implies, is heavily specialized in killing goblins. A weapon poorly suited for that role is a weapon he doesn't want.
- Gundam is rich with its own share of BFS, since technically every beam saber used are suitably large enough to be used for the mobile suits who are at least 15 meters on average. Many mobile suits are taller than that, and even more have swords bigger than they should be:
- Mobile Suit Zeta Gundam: Zeta Gundam's beam saber is fairly standard, but the Psychic Powers of its pilot Kamille Bidan can enhance its length to an impressive size.
- There's also the Double Zeta's Hyper Beam Saber, which is one of Double Zeta's beam cannons that can be converted into a beam saber; it is nearly twice as long as the average beam sabers. Their more recent appearances in Super Robot Wars really ramp up how big the sword gets.
- The Shining Finger Sword. Just watch the thing in action from Mobile Fighter G Gundam.
- Mobile Suit Gundam F91 spinoff manga Mobile Suit Crossbone Gundam has the Crossbone Gundam X-3, whose signature "Muramasa Blaster" is a fairly large sword to begin with but gets much bigger when the fourteen beam sabers built into it are activated. (It also has a beam rifle built in.)
- The V2 Gundam pulled this as well in its final battle, though the saber didn't grow in width, just in length. It also has the "Wings of Light", a pair of beam wings whose primary role is propulsion but can also function as kilometers-long beam sabers.
- Mobile Suit Gundam Wing has Epyon, the Evil Counterpart to the main character's Wing Zero. While Zero wields a Wave-Motion Gun BFG, Epyon has a beam sword powered by a direct connection to its nuclear fusion reactor, meaning its size can grow to incredible lengths. This can be seen in one episode where Epyon's pilot extends the sword to incredible size and uses it to slice through the colony-sized space fortress Barge length-wise. To put that into perspective, Barge is a giant cylindrical fortress about 8,000 meters long.
- Wing also has the Endless Waltz version of Gundam Sandrock. In the TV series, its heat shotels are longsword-sized weapons that happen to have a C-curve◊; in EW, they're as big as Sandrock itself◊.
- Mobile Suit Gundam 0083: Stardust Memory has the Gundam Physialis, which possesses a beam saber with a larger size and intensity than normal ones. Gato once over-charges it to overpower the beam saber of Kou's Zepyranthes. The series also introduces the giant mobile armor Orchis, which wields a gigantic beam saber whose handle is about as big as the (normal-sized) Gundam that controls the Orchis, and produces a blade as long as the entire thing. Its rival Neue Ziel also has a pair of beam sabers which fit its enormous size on its hand claws, though it is slightly shorter and thicker than Orchis'.
- Mobile Suit Gundam SEED introduced anti-ship swords, which are sword-shaped cheese slicers with energy blades on its edge, using the extra weight for impact (although non-beam edge variants exist such as the Grand Slam sword and the anti-ship swords carried on the IWSP pack. Both are able to be used by the Strike and its variants, although they were never featured in the anime). In Destiny, the anti-ship swords are reused by the Impulse, Sword Calamity, and Strike Noir Gundams which carry a pair (though Strike Noir's are somewhat shorter) as well as the Destiny, which carries one. In addition, there is the METEOR units, a huge support unit operated by the Freedom and Justice Gundams which feature a pair of huge beam sabers on each arm. At one point, Kira uses one to cleave an Agamemnon-class carrier in half lengthwise with a single blow. For reference, an Agamemnon-class carrier is 300-meters long.
- The spinoff manga Mobile Suit Gundam SEED Astray has two more examples: Blue Frame's Tactical Arms, and Red Frame's Gerbera Straight II, a hundred-and-fifty-meter katana, requiring special equipment just to use it. The katana is more than eight times as long as the Red Frame's height (and similar to the length of mothership), and unlike the other examples in Gundam, it's not a beam weapon but an actual metal sword. At one point, Lowe impales a battleship with the Gerbera Straight II, as the battleship is only 130 meters long. If you have to ask why Lowe Gear decided to forge a 150-meter katana, he just thought it would be awesome to have a katana that large and really, can you disagree?
- The title mecha of Mobile Suit Gundam 00 normally wields a pair of average-sized swords, but can get into BFS range when the built-in beam sabers are activated. And then when combined with the 0 Raiser support fighter to form the 00 Raiser, in Trans-Am mode it can form two gaint beam swords that rival even the Shining Finger Sword in size.
- The spinoff Gundam 00V supplemental material includes the 00 Gundam Seven Sword variant, with one of the seven swords being a physical blade (the GN Buster Sword II) that's taller than the mecha itself and weighs about 10 tons.
- Episode 17 of the second season contained one of the largest examples in the franchise: the Raiser Sword. 00 Raiser in Trans-Am mode is able to create a truly MASSIVE beam saber capable of reaching up to orbit to slice in half the Memento Mori while the 00 Raiser is at the edge of the Atmosphere. According to the background material the Memento Mori is on an orbital ring 10,000 kilometers above the Earth's surface. The crew of Memento Mori is initially relieved when the "beam cannon" fired at them missed...until they realize it's a sword, which gets lowered down to slice through them.
- Note that the sword itself is stated by Word of God to be about 10,000 kilometers long. The Mecha that wields it is 20 meters tall. That means it wields a sword that's 500,000 times longer than the Mecha is tall!
- Gundam Build Divers Re:RISE featured these examples:
- The Nu-Zeon Gundam's main handheld weapon is the enormous Zeonic Sword that can be used in 2 different modes as either the Hi Mega Bow Gun or the Hi Mega Saber mode in which the weapon can either emits a long beam saber or a beam replica of the Axis asteroid which can then be dropped on enemies and destroying them instantly.
- The Gundam Aegis Knight in its King Mode can combine all of its weapons and side skirt armor parts to form the Keraunos Hyper Beam Sword, which can emit a massive green beam blade with maximum power.
- But the crowning king of Gundam BFS's has to be the Helmwige Reincar's Valkyria Buster Sword from season 2 of Mobile Suit Gundam: Iron-Blooded Orphans. Handles fully extended, this thing is TWICE as tall as the Mobile Suit it's equipped to (The Helmwige is 21.1 meters, meaning the sword is at least 42 meters). Functionally, it's more of a Double Weapon that where the lower half can split to act as a club, leaving a sword that's STILL huge, just as big as the MS itself. It's SO big that it can only be stored on its crotch in a way as if it was still being held. It's SO big that its feet expand just to give it enough stability to wield the thing. It's SO big that it's treated by fans as the main attraction of the High Grade kit...and the MS as a mere accessory for it.
- Mobile Suit Zeta Gundam: Zeta Gundam's beam saber is fairly standard, but the Psychic Powers of its pilot Kamille Bidan can enhance its length to an impressive size
- The Heavy Blade class in the .hack series all wield these as a rule. For some reason, another rule for this class is skimpy armour for females, but that's another story entirely.
- (Most of) The male Heavy Blades also use skimpy armor, but you don't get many of those on your team.
- As far as this series is concerned, Black Rose's new blade really takes the cake!!
- .hack//G.U. Trilogy: Haseo in his B-st form. He is Dual Wielding Chainsaw Good BFS, complete with field of BFS.
- Hanaukyō Maid Team La Verite episode 11. Captain Konoe Tsurugi's Onee-sama has one almost as tall as she is, which she uses against Konoe during their battle.
- Shidou "Sid" Misako from Hayate X Blade has a sword that is notably bigger than most of the other girls'.
- Inuyasha's sword Tessaiga is a normal-sized and rather dull-bladed katana in its unempowered state, but transforms into a BFS for use in battle whenever he has the desire/resolve to protect a human. Bankotsu's Banryuu, though technically a halberd, makes an even bigger BFS than Tessaiga.
- On the other hand, the three swords wielded by Master Swordsman Sesshoumaru are all of normal size.
- Jakotsu's sword looks like its only a bit bigger than average, if that. In reality, its actually a bunch of very thin, very hard blades attached tip-to-tip which he can swing around with an incredible amount of force and control.
- Lapis from Kaze no Stigma carries a BFS which can nullify jutsu/magic.
- From Kill la Kill, Ryuko Matoi has half a scissor. That can transform to the size of a sword. Which can triple in length. In the Episode 25 OVA, she supersizes the blade into a several thousand foot monstrosity in order to fight a Giant Mecha.
- Kurohime gets a Laser Blade and cuts earth in half.
- Lyrical Nanoha has Fate Testarossa and her intelligent device, Bardiche. Not only does its Zanber Form start out larger than she is, but it can grow to such immense length that Fate could cleave through Humongous Mecha at a distance. Slightly justified in that Bardiche only transforms into its hilt; its blade is made of magical energy, which means that Fate can extend the blade further so long as she has the mana to spare.
- While not quite as oversized as Fate's, Signum's Levantine/Laevatein/Laevateinn is still (depending on artist and camera angle) longer than she is. Her new sword in the FORCE manga is even bigger.
- Cypha has two. Vita's Graf Eisen can upsize to the point that she's invisible when showing its full size. And Deville's axe. Goodness.
- Magic Knight Rayearth:
- When Fuu's Escudo sword evolves, it just gets bigger, to the point where it becomes longer than she is tall. It also weighs a ton if anyone other than her tries to use it, although that has more to do with its made-just-for-her nature than its mass. (In contrast, the other girls' swords gain more elaborate designs on the hilt.)
- The Mashin/Rune Gods themselves wield BFSs, but they're large magical mechs, so It Makes Sense in Context.
- Magi: Labyrinth of Magic:
- Alibaba's sword Amon takes the form of an enormous, and extremely wide black sword which also has fire powers. Since the size is so different from it's normal sealed form, he has trouble wielding it without performing a full-djinn equip.
- Ren Kouha's blade on the other hand makes Amon seem tiny. Kouha's sword is basically a giant cleaver that's even bigger than his entire body, (although that's partly because he's not very big himself) and it's magical abilities allow it to grow even bigger, to the point that he could use it as a shield for a large portion of his army.
- The Kaiser Blades from the Mazinger Z OVA series Mazinkaiser. The movie sequel has two smaller blades that are deployed from the shoulders, but the original/Final Kaiser Blade was pulled out of Kaiser's chest, was three times the length of Kaiser, and able to cut through damn near anything.
- While Mazinkaiser wields three swords named Kaiser Blade, the main one is the technical BFS. It is ejected from its chest, requires both hands to wield and is powerful enough to cleave Hell King Gorgon in quarters. It's no wonder that Super Robot Wars games that use the Mazinkaiser OVA storyline refer to this weapon as "Kaiser Blade Full Power".
- The Medicine Seller from Mononoke has a weapon that is less of a sword and more of a blazing energy blade attached to a sword handle. It can be just as long as it needs to be, including building-length.
- Mikoto from My-HiME fits the main trope when she becomes a Dark Magical Girl later in the series.
- Arika from My-Otome is the proud wielder of both a BFL◊ and a BFS◊.
- Arika gets one-upped by her own mother in My-Otome 0~S.ifr~. Her version of the Sword of Akatsuki is large enough to cleave an asteroid in half from several hundred meters off.
- Naruto:
- Zabuza, an ex-Seven Swordsman of the Mist and the first major villain that Team 7 faces has a rather nasty BFS named Kubikiribouchou ("Decapitating Carving Knife") that can repair itself with the iron from the blood of its victims. Kisame (also a former member of the Seven) has another BFS named Samehada ("sharkskin") that only he can use, and which is more or less a sword-shaped bundle of hooks as opposed to an actual blade. Its main strength is its ability to absorb the chakra of others in order to aid its master, and Kisame can also fuse with it if need be. It also happens to be alive, to the point where it's capable of abandoning its master if it finds someone else it likes better.
- Expanding on Zabuza, Kishimoto said Zabuza's early character designs had his sword about the size of a skycraper, or at least a small building.
- Outside of that group, the Raikage's bodyguard Darui has a sword that is a giant cleaver/ax with no point. It seems to be able to fold along a pivot sideways to be stored easier.
- Gamabunta's tantō (which for him is regular-sized) was temporarily used by Tsunade as an insanely giant sword.
- Yet another one of the Seven Swordsmen, Chojuro also has a pretty big sword, but when he really lets loose his "Hiramekarei" will reach BFS status due to the powered up chakra.
- The Sword of Nunbaku, formed from the Six Paths' Truth-Seeking Orbs, is a titanic DNA-shaped sword that can destroy and reform the landscape at the user's whim. Unfortunately, despite being presented, it never actually got used.
- Zabuza, an ex-Seven Swordsman of the Mist and the first major villain that Team 7 faces has a rather nasty BFS named Kubikiribouchou ("Decapitating Carving Knife") that can repair itself with the iron from the blood of its victims. Kisame (also a former member of the Seven) has another BFS named Samehada ("sharkskin") that only he can use, and which is more or less a sword-shaped bundle of hooks as opposed to an actual blade. Its main strength is its ability to absorb the chakra of others in order to aid its master, and Kisame can also fuse with it if need be. It also happens to be alive, to the point where it's capable of abandoning its master if it finds someone else it likes better.
- Negima! Magister Negi Magi:
- Asuna's Paper Fan of Doom can upgrade into a BFS. How this works depends on whether it's in the manga or the Alternate Continuity anime series Negima?! In any case, the fan is mainly for comedy (or sparring), while the sword is the business version.
- Meanwhile, Jack Rakan, a comrade of Negi's father, is known as "Rakan of the Thousand Swords". Apparently, it seems, including one the size of a skyscraper.
- Asuna's classmate Kaede is a semi-closeted Ninja whose signature weapon is a four-pointed Big Fuuma Shurikennote which is considerably wider from tip to tip than she is tallnote . Also, she sometimes seems to pull it out of nowherenote .
- Setsuna. That nodachi of hers is taller than she is (necessary for the demon-slaying work of her sword school).
- In weapon-to-wielder ratio, the sword that Evangeline's puppet Chachazero uses, mostly in Negima?!, also counts. It's not an unrealistically large sword, but not one that would be easy to wield one-handed. Chachazero does it just fine, though. She's less than a foot tall, making the sword seem absolutely gigantic.
- Yue has started wielding a sword that's longer than she is tall. She even manages to kill a powerful demon with it.
- Quartum can summon a pillar-sized sword with a spell. And it's on fire.
- Given that Ku Fei's pactio weapon is a staff based on the Ruyi Jingu Bang, and thus can expand to any size at will, it has at times been the largest melee weapon in a series packed with them.
- Tessai in Ninja Scroll carries a huge double-bladed sword that he can throw like a boomerang. It plays a big part in his own death.
- One Piece:
- Mihawk's main sword Yoru. Can be mistaken, however, for a grave cross. The first time you see Mihawk's sword, you can easily mistake it for a giant marble cross that he's resting against. Then he draws it. The sword is bigger than he is. It gets progressively more badass afterwards, to the point where he can use it to slice a (frozen) tsunami wave bigger than a fortress in half with it. Horizontally in half. Plus Mihawk has a whole pack of killer baboons who wield similar great swords to him on his island; Zoro had to fight the whole pack if he wanted a chance of receiving Mihawk's training.
- Inverted by the same character, when he wields a tiny dagger against Zoro's three swords to give himself a handicap. He still wins.
- Smoker's jitte isn't nearly up to Mihawk's standards, but it is still pretty huge.
- Whitebeard's glaive is in proportion to his body size, and the guy's 20 feet tall.
- Arlong's secret weapon is a huge, saw-shaped sword called Kiribachi (Cutting Plectrum, called the Saw Blade in the anime dub).
- Points for originality go to Funkfreed, Spandam's sword. It's a relatively average-sized sword that can transform into an elephant.
- The nodachi Trafalgar Law wields is nearly as long as he is tall, to the point that he carries it around in hand because the length doesn't allow him to strap it to his side.
- Mihawk's main sword Yoru. Can be mistaken, however, for a grave cross. The first time you see Mihawk's sword, you can easily mistake it for a giant marble cross that he's resting against. Then he draws it. The sword is bigger than he is. It gets progressively more badass afterwards, to the point where he can use it to slice a (frozen) tsunami wave bigger than a fortress in half with it. Horizontally in half. Plus Mihawk has a whole pack of killer baboons who wield similar great swords to him on his island; Zoro had to fight the whole pack if he wanted a chance of receiving Mihawk's training.
- Jio Freed in O-Parts Hunter eventually carries a Big Effin' Boomerang/Ninja Star whose size and amount of damage it can inflict is proportional to the fear and hate a person has. Thus to a fearful mook the thing fills the entire sky while to a pure-hearted angel it's a useless ring of metal (unfortunately the angel works for the bad guys).
- Mewtwo from Pokémon Adventures has a Big Friggin' Spoon, formed from psychic energy. No matter how stupid it may sound, it serves as an extremely effective close-range melee weapon, and it can stretch, curve, and turn into a fork to spear things with. And he once used it to deliever a Diagonal Cut on the Trainer Tower, slicing the building in two.
- Alice L. Malvin from Pumpkin Scissors has Mahne, a double-bladed sword meant to be used by cavalrymen. She uses it on foot, and wears a pair of sabatons in conjunction with it for the express purpose of kicking it free when one of the blades inevitably gets lodged in the ground.
- Cattleya from Queen's Blade wields a giant two-handed sword appropriately named "Giant Killer".
- Being that Ranma ½ is more a comedy than anything, it doesn't allow many blades of any size to get in. Shampoo still manages to get away with swinging around a massive sabre in her first appearance, even if she does trade it for Carry a Big Stick afterwards. How big is it? The blade alone is roughly the same length as the distance between the bottom of Shampoo's pelvis and the top of her head. And she swings it around in one hand. While carrying a chui (a long-handled mace with a basketball sized solid steel head) in the other.
- Ukyo fights using a huge okonomiyaki spatula.
- The Ten Commandments sword, used by Haru Glory in Rave Master, is nearly as large as its wielder. Luckily, this only applies to its base form, Eisonmeteor; its other 9 forms are much more reasonably sized, with the exception of Gravity Core, which is even larger.
- All BFS wielders in the series (and probably all BFS wielders in history) bow before the might of Uta the Eternal, who wields a sword 100 feet long and over 10 feet wide, even though he's only human sized (at least initially). It's seriously insane.
- Explored in CLAMP's debut manga, RG Veda, in which a major character carries one, and remarks that it wouldn't ever be able to cut anything, had the sword not been magical.
- In the manga Rikon Choutei, the protagonist has a really big sword, so big that [[spoiler:he is cutting the Earth to the core with his sword. It's actually part of a divorce process.
- Rurouni Kenshin:
- Sagara Sanosuke starts out with a BFS (a zanbatō, in fact) and a rotten attitude. It was his weapon of choice, hence his nickname (Zanza). Kenshin destroys it during their last fight. He says it is impractical and proceeds to easily outmaneuver the sword, which is bound by the laws of physics (especially momentum) to be a clumsy weapon. None of this stops Sano from breaking it out one more time in the Jinchū arc and showing it can be used for other things like playing baseball with cannon shells.
- Fuji of the Juppongatana also wields a tremendously gigantic sword. Fuji is gigantic in his own right, the sword being an oversized hunting knife large enough to allow him to demolish a building.
- Some of the Humongous Mecha/Samurai in Samurai 7 use swords so large that they are actually independently pilotable vehicles. In the last few episodes the titular heroes use one as transportation. And Kikuchiyo (who has a cybernetic body himself, but merely the size of a large human rather than a mecha) actually wields one during his Heroic Sacrifice scene.
- Sgt. Frog: In the first chaper of the Musha Kero saga, the first of the five crystals our heroes recover turns into this, just in time to grant Keroro a Moment of Awesome.
- God Keron is known to carry two of these.
- The other Humongous Mecha, Keroro Daishogun, that appeared at the end of the Musha Kero saga, had an even bigger one.
- God Keron is known to carry two of these.
- In Shakugan no Shana, Sorath has one he calls Blutsauger. Both Tanaka and Satou later make several attempts to lift it, but neither of them succeeds to get it off of the ground completely. In Season 2, Yuji takes a level in badass and wields it with ease, at one point throwing it one-handed as a finishing move.
- Silent Möbius features the magical shape-shifting sword Grospoliner, a sentient weapon of ridiculous size in its sword form. However, Katsumi rarely (or never) uses the blade of the sword to cut enemies, instead mainly using the weapon as a magic-focusing tool.
- One of Tsubaki's forms in Soul Eater is a katana called the Fey Blade. For some reason, after Black* Star's last fight with Mifune in the anime, it increases in length to up to twice, if not three times, the original length.
- A scythe example, Soul's Witch/Demon Hunter form is also massive. One of Ragnarok's equivalent modes makes him considerably larger than usual.
- Ideon from Space Runaway Ideon. One of its weapons, the Ideon Sword, a beam of pure light emitted from each of Ideon's hands. While the beam's destructive power is immense (even cleaving a planet in half at one point), its most peculiar quality is its length. While adjustable, the maximum length of the sword is depicted as being quite possibly infinite.
- Sword Art Online: When Kirito shops for equipment in ALO, he chooses one of those claiming regular swords are "too light".
- Symphogear: Tsubasa Kazanari's Symphogear is powered by a fragment of a legendary katananote and has the power to create swords. These can range from reasonably-sized but capable of lighting on fire to building-sized rocket-powered monstrosities that fall from the sky, and that's without using X-Drive mode. All made possible by The Power of Rock. It's that kind of show.
- In the first Tenchi Muyo! movie, Achika ends up turning Tenchi's sword, usually a lightsaber-ish weapon, into a massive energy blade, capable of cleaving Big Bad KAIN in half.
- In Tenchi in Tokyo, when the seven jewels Tenchi and the girls hold are united, they form into a massive crystal sword. Which Tenchi doesn't really use because he's such a Nice Guy.
- Kenshi Masaki in Tenchi Muyo: War on Geminar Has the Tenchi-ken, a sword made from a compressed mountain!
- Kamina from Tengen Toppa Gurren Lagann has one of these. He often makes a Rousing Speech when he draws it, and the longer the speech, the longer the sword, because Rule of Cool.
- In the final fight with the Anti-Spiral, the TTGL uses giant versions of Enki's swords. Oh, and did I mention the TTGL is 13 billion lightyears tall? That's a BFS! Actually, two BFS!
- Also, in the second TTGL movie Viral pilots a galaxy sized mech with 14 arms. Guess what 11 of those arms are wielding? Granted, they're not as big as the TTGL's BFS, IMO quantity over quality in this case.
- Also, in some official art of the Tengen Toppa Gurren, King Kittan, and Agodega, (which never appeared in the manga/anime/movies, you clearly see that the TTG is wielding a katana, like Kamina. The TTG is, you guessed it, galaxy sized. Considering Kamina's normal katana is already a BFS, the TTG's katana is a BFS of a BFS.
- Aya and Maya from Tenjho Tenge share a long, long katana that could not be wielded by either of them, y'know, in the real world.
- Torture Princess: Fremd Torturchen: Elisabeth Le Fanu's weapon of choice aside from conjured chains and torture and execution implements is the Executioner's Sword of Frankenthal, a longsword that, much like real executioner's swords, is rectangular with a blunt tip.
- After breaking four ordinary swords in a fight, Karula from Utawarerumono upgrades to a BFS that only she is able to lift; however, because she demanded it be unbendable, unbreakable, and never need sharpening, the edge is not as sharp as a regular sword, so people she hits with it tend to splatter. She tests it out by splitting a giant boulder. Several strong men had difficulty even carrying it.
- And then she breaks that one too, which is never mentioned again because it's back for her next fight.
- D's Masamune from the two Vampire Hunter D movies definitely fits this trope — if it wasn't for the curve of the blade, it would drag the ground whenever he wields it. As it is, it's a miracle he can unsheath it, let alone wield it with the superhuman speed he does. Well, he is a dhampir after all.
- While it's not particularly huge, Trom Bone from Violinist of Hameln wields his father's sword, which is a bit large for a boy his size. Hamel, on the other hand, wields a BFV?a Big Fraggin Violin.
- Balgus from The Vision of Escaflowne gets one in the second episode, when facing off against the Zaibach cloaked Melefs. Considering these things managed to incapacitate with ease several other melefs (for reference, melef=15 foot tall mecha), the fact that Balgus proved harder to kill when on foot and armed only with his 8-foot long sword makes him even more awesome.
- Averted in Yaiba, relatively speaking. Despite having a lot of swords and weapons, Aoyama rarely uses this trope. Yet, Kojiro's Laundry Pole has the power to grow really really long.
- Also the Devil King Sword (Mao Ken) is quite large compared to Gekko. Gold in the Underworld arc wields a gargantuan scimitar, but is quite justified because it fit its size.
- A number of monsters in Yu-Gi-Oh!, including Flame Swordsman, Swordstalker, Buster Blader, Amazoness Swordswoman, and Gilford the Lightning. A monster with a sword that is not a BFS is just out of place.
- Arguably the most ludicrously oversized sword in the series belongs to Gilford the Legend in Yu-Gi-Oh! GX. While it's pretty big in the first place, the guy who summoned Gilford proceeds to equip several more swords onto him, each of which is absorbed into Gilford's sword, making it even bigger. By the time he's done, the sword easily measures over twenty feet long.
- In Yu-Gi-Oh!: Capsule Monsters, Black Luster Soldier has one by default. Yami also gets some with his Black Luster Soldier and Blue-Eyes White Dragon armor.
- In Yuki Yuna is a Hero, Fuu has one of these as her main weapon. When she activates Mankai, it becomes skyscraper-sized, big enough for Togo to run along the blade’s edge. That’s one way to “carve a path.”
- Earth from Zatch Bell! is the king of this trope. All of his spells revolve around his sword, which isn't too big for demon standards. However, some of his spells increase the size of it. Jian Ji Sorudo causes a huge sword to form at the tip of his, which he can use accordingly. Varusere Ozu Maru Sorudon is one of his last resorts, in which he just makes it rain BFSs. It is shown that if he had stayed in the fight longer, he would've awoken Shin Varusere Ozu Maaru Sorudon that just causes him to summon more, larger, stronger raining BFSs.
