Leg Cannon

Go To
A Sub-Trope of Unusual Weapon Mounting and sister to the Arm Cannon, the Leg Cannon is a cannon mounted on a leg, hidden in a leg, or IS the leg. Expect many of the same features as you would on an Arm Cannon, such as Bottomless Magazines and being fired on thought alone, if only because you could not easily reach a trigger mounted on your own shins.

  • The Big O: Big Duo launches ICBMs from them.
  • In one City Hunter arc, a bad guy who was humiliated by Ryo Saeba turns himself into a weapon, using an assault rifle for an arm and a Grenade Launcher for a leg. Neither weapon does him much good against Saeba in the end, even dying because of his leg bazooka, as Saeba shot a bullet in the barrel as he was about to launch his grenade.
  • In Cyborg 009, Albert/004 has rocket launchers installed in both of his legs. In a certain scene of the 2001 anime, he leaps in the air and swiftly fires both rockets at the same time.
  • Daitarn 3 has the DAITARN LEG CANNON!
  • Digimon Ghost Game: WezenGammamon has auto-cannons for legs, with two barrels under each foot. For added fun (and firepower), he’s a rare four-legged example.
  • Hyakkimaru from Dororo has a cannon that fires upwards out of his lower leg.
  • Fullmetal Alchemist: the pickpocket Paninya has rather unique automail legs, one of which has a 1.5" carbine housed in her left knee.
  • The villainous Bonnie in Gunsmith Cats first encounter went badly for her: Rally shot her thumb off and one of May's grenades blew off her legs below the knee. When she returned for revenge her new prosthetic replacements included a shotgun in one leg (with a bomb in that foot) and a thumb that included a garrotte.
  • Mobile Suit Gundam Wing: all incarnations of the Heavyarms Gundam have leg mounted missile launchers, among other things.
  • Post One-Year War variants of the Zaku II produced by the Zeon, and its successor, the Titans-produced Hizack, feature leg mounted missile launchers.

  • In Mobile Suit Gundam AGE, Gundam AGE-1 Spallow has needle guns which can be launched from its knees.
  • Mazinger Z: Mechanical Beast Deviler-X1 had cannons mounted inside his legs. The Beast blew one entire Mazinger's arm off with one of them. Ouch.
  • One Piece:
    • Buggy the Clown, who somehow manages to hide a functioning gun in his foot with the proportional power of a giant cannonball that can be used to level cities. It's not clear whether it's actually in his foot or his shoe, however, but seeing as his super power is the ability to harmlessly separate individual parts of his body, there's a lot of wiggle room.
    • Baby 5, who has the ability to turn her limbs or whole body into any weapon of her choice, has been seen transforming her leg into a machine gun.
  • Grey the Ninelives, a Killer Robot in the anime of Trigun (as opposed to the manga, where it was a horde of dwarves in Powered Armor) has a rocket launcher in its thigh that it uses to destroy its target after its upper half is destroyed.

  • In The A-Team, Mexican river pirate El Cahon has a shotgun in his fake leg. When cornered, he likes to nonchalantly rest it on the table, and then sucker-blast people. He tries it on Hannibal, but the paper shells were waterlogged from an earlier wade in the drink.

  • Tokusou Robo Janperson: Janperson mounts at least one Kneekick Missile in his right leg, more or less identical to Albert/004.

  • Occasionally, in BattleTech, some 'Mechs carry weapons in their legs. In spite of the importance of their legs to the 'Mech's effectiveness, the limited space and aiming restrictions for the leg locations means most 'Mechs don't mount weapons there, and heat sinks or jump jets are far more common alternatives. Notable examples of 'Mechs with leg weapons included the light Wasp and the heavy Crusader, both of which carry leg-mounted short range missile launchers. One particular piece of equipment called the A-Pod (antipersonnel-pod) is unusual in that its only allowed mounting points are in the legs. As it is essentially a leg-carried claymore mine, this is justified— infantry making focused attacks on 'Mechs have to scale them first, and these mines easily shred conventional infantry.

  • Honorable mention goes to the type 89 and type 10 grenade dischargers, Japanese infantry light mortars that when captured were sometimes briefly thought to be designed to be fired with the curved base plate on the thigh. The type 10 in particular due to a mistranslation. (The designation of "leg mortar" led to quite a few Australian soldiers being cas-evacced from New Guinea with shattered thighs, after stocks of this weapon were captured in one of the first Allied victories of the Far Eastern war).
