Vote up the weapons that are so needlessly big they move past ridiculous and circle back to amazing.

One of the greatest things about anime it that it doesn't have to follow the rules of reality. Whether it's four-foot tall girls wielding swords bigger than them, or shy nerds somehow getting a harem of girls obsessed with them, anime doesn't play by the rules, man. Of course, this means that there are a lot of weapons in anime that are so huge, they would actually be a massive liability for anybody to wield in real life.

A minor quibble: giant robots don't count as weapons. What does count are the weapons wielded by giant robots which are still way too big.

Here are the most absurdly, improbably, and ridiculously big weapons in all of anime. This is going to be sweet.

    Dragonslayer From 'Berserk'

    Guts is the great-granddaddy of big dudes wielding bigger swords, and his chosen weapon looks the part. Huge, simple, and dangerous, this thing looks like it is ready to mess up somebody's day. Big time. Get it?

    Punisher Cross From 'Trigun'

    Nicholas D. Wolfwood’s Punisher Cross is the Swiss Army knife of guns. You know, if instead of being portable, Swiss Army knives were the size of an adult person. In addition to being massive enough to use as a shield, the Punisher also contains a machine gun, a grenade launcher, and small armory of hand-held pistols.

    Kubikiribocho From 'Naruto'

    This humongous machete’s name roughly translates to the “Decapitating Carving Knife.” Apparently, this is what passes for a "knife" in the Naruto universe. Their steaks must be epic.

    Gideon From 'The Seven Deadly Sins'

    Embedded in a mountain and ostensibly too large for any man to wield, "Gideon" is the name of a huge hammer. Even the giantess who wields this weapon, Diane, is dwarfed in comparison to the thing. Massive doesn’t even begin to cover it.

    Harkonen From 'Hellsing Ultimate'

    Harkonen is a massive anti-tank rifle that Seras Victory wields like a regular rifle. As if that wasn’t rad enough, she dual wields them later in the series. Best of all, this happens in a setting where she is one of the weaker vampires. Guess size doesn't matter in the Hellsing universe.

    Zanbato From 'Rurouni Kenshin'

    Zanbato is massive, and also the single most generic weapon on the list. It's just a big piece of sharp metal on a stick. How generic is it, you ask? Generic enough that Sanosuke, its wielder, stopped using it after only a few episodes. Presumably for an even bigger sword that also shot fire, or whatever.

    Though not technically weapons, there has to be an exception for the Galaxy Shuriken. No, "Galaxy Shuriken" is not the name of the weapon, these are just actual, full-sized galaxies used as projectiles by an unimaginably big robot.

    Bustermarm From 'Fairy Tail'

    See how Bustermarm’s wielder has to fly in the air to even point this thing menacingly? This sword is so large it crosses the line from being intimidating to just plain goofy.

    Bui's Axe From 'Yu Yu Hakusho'

    Bui is tall as a tree, built like a house, and has the anime standard eight-pack abs. Even so, his axe still looks way too big for him. Like, you could never chop firewood with that thing.

    Before Bleach got all sorts of insane (what even is a "Quincy," anyway), the series started off with a man, a sword, and a dream. Presumably the "dream" was to wield a massive butcher knife that looks like it should be in a horror movie, because that’s the one that came true.

    Tessaiga From 'Inuyasha'

    Tessaiga is a classic big ol’ katana. You know, totally awesome. The sword has a mind of its own and has the ability to absorb the powers of defeated enemies. Appearing as a normal-sized (and rather battered) katana normally, it transforms into its gargantuan form when wielded by a demon who cares about a human.

    Mami's Derringer From 'Puella Magi Madoka Magica'

    Mami’s Derringer is counterintuitive to everything you know about small guns. While it's nominally a derringer, it's completely massive. Forget about having a strong trigger finger, you need to give this thing a bear hug just to fire it!

    Double Medium From 'Shaman King'

    Double Medium is huge, but only sometimes. Because it is made of “spirit energy,” the Double Medium can be as big or small as it wants and still weigh the same as a normal-sized katana.

    Nobody actually catches boomerangs when they come back. That's an objective fact. It hurts like hell, and it's super hard to do. Nobody, not even a badass demon hunter, could catch a boomerang as hilariously over-sized as Hiraikotsu when it comes back.

    In a medium full of person-sized swords, Yoru goes the extra mile by having something none of its competitors have - an equally stupidly sized hilt. The mystery as to how anybody could possibly wield this thing, even if they were strong enough to lift it, will endure until the end of time.

    Positron Sniper Rifle From 'Neon Genesis Evangelion'

    The Positron Sniper Rifle from Neon Genesis Evangelion is so large, not even a giant robot can wield it standing up. They have to go prone. Additionally, it's so electricity hungry that firing it causes the entire city of Tokyo to have a blackout. But hey, that's your Second Amendment right.

    Demon Slayer Sword From 'Black Clover'

    Although it's an old and ancient Anti Magic Weapon, the Demon Slayer Sword proves to be quite useful for a wielder like Asta. It's not just great for cutting down magic. You can also manipulate the sword's Anti Magic and use it as a flying hover board. It's definitely large enough to stand on, so why not?

    Judgement of the Ten Heavenly Kings From 'Akame ga Kill!'

    Seryu Ubiquitous possesses the "Judgement of the Ten Heavenly Kings" which consists of ten powerful weapons that serve as modifications to her body. Therefore, she can easily switch between them as they're an extension of her. And of course, each of the weapons are insanely massive. Go big or go home, right?
