One of anime's biggest draws lies in its battle and fight scenes, always made more epic by the introduction of cool guns and weaponry. Gunfight scenes in anime elevate the gunslinger trope to another level by giving the fighters unique firearms with abilities you hardly see in other media, much less real life.
The very best anime guns do more than just fire bullets; they shoot flames, cast spells, and even possess souls of their own. Only the finest anime gunslingers are capable and deserving of such formidable weapons, whose power is sometimes even beyond their control.
While Trigun's Vash the Stampede never shoots to kill, he always arrives to save those in danger with his AGL Arms .45 Long Colt revolver. The silver revolver is part of a pair created by Vash's twin brother, Knives, and holds a dark power. Vash's revolver transforms into the Angel Arm canon, a weapon so powerful Vash once lost control of it and blew a hole in the moon.
Though both of Alucard's Casull guns boast considerable firepower, the vampire needed extra destructive force to injure his most deadly enemies. Thus, the Jackal was born. While the handgun is too heavy for mortals, the supernatural Alucard uses the Jackal with ease to mow down enemies in the world of Hellsing. Against one vampire, the Jackal managed to take out an entire leg with a single shot.
Weighing in at 300 lbs, the Punisher is the large cross-shaped gun of Nicholas D. Wolfwood. This non-Vatican approved weapon boasts two machine guns and one rocket launcher, and even carries sets of backup pistols. One of only 10 in existence, the Punisher's over-the-top firepower solidifies it as the most famous gun from Trigun.
Most partnerships in Soul Eater involve a master and a living weapon, such as Maka and her scythe buddy Soul. Death the Kid, however, teams-up with two demonic sisters, Liz and Patty, who transform into Demon Twin Guns. While the Thompson Sisters differ in personality, their combined might provides spiritual ammo for Kid to fire and internally wound his enemies.
