Swordplay can add some serious visual panache to any anime. Though the medium allows for a wide variety of mythical and imaginative weapons, swords seem to be the tried-and-true instruments of animated mayhem.
There are plenty of noteworthy swords in anime, but the greatest blades are obviously the ones with legendary backstories. While the Tessaiga can slay 100 demons at once, it's the myths surrounding the sword that distinguish it from the bargain-bin sabers.
A blade should be judged by its appearance, its destructive capabilities, and by the fortitude of its wielder - the very best swords will brandish all three.
Zangetsu is Ichigo's Zanpakuto, a device with powers that vary depending on the contents of the user's soul. Their primary function is to help Shinigami bring stray souls to the afterlife. Zangetsu is the first Zanpakuto in the Bleach universe to take on a human form.
Specifically, his form represents Ichigo's hidden, darker thoughts and emotions.
The tessaiga was originally created using one of Inuyasha's father's fangs alongside its sister sword, the tenseiga. Inuyasha inherited the sword from his father, while his brother Sesshomaru inherited the tensaiga. Inuyasha's grisly blade is capable of slaying 100 yokai (demons) at once. At its most powerful, it's able to send whatever it touches to Hell.
By contrast, the tenseiga can restore life, making it just as impressive if not more so - but because the tessaiga is considered more powerful, Sesshoumaru feels slighted by their father and deeply resents his brother Inuyasha.
The Dragon Slayer is less a sword than a giant club made of iron. It can slice, but it's more likely to crush via sheer brute force. Guts is one of the only people capable of wielding it, as most others buckle under the weight.
Not everyone can handle the power that comes with the epic Dragon Slayer.
Calling Ea a sword is like calling Shou Tucker from Fullmetal Alchemist a jerk - it's technically true, but it's also a massive understatement. Ea created the world by slicing it away from the heavens. It contains the secrets of the universe, and it's entirely capable of wiping out the planet should its wielder choose to do this.
It's also impossible to replicate because it's made of materials that can't be found on Earth. As one might expect, this sword can't be wielded by just anyone; only Gilgamesh can handle Ea.
