History Main / ArmCannon

* ''ComicBook/TheWarlordDC'': After [[BackFromTheDead being resurrected]] by Deimos, the mercenary Chakal had his right arm replaced with an energy weapon.

** Most protagonists in the series have one. It includes [[VideoGame/MegaManClassic Mega Man]], [[VideoGame/MegaManX X]], [[VideoGame/MegaMan Model X]], and [[VideoGame/MegaManLegends Volnutt]]. In the former two cases they also fire most [[PowerCopying copied]] Special Weapons from it.

** [=MegaMan=].EXE in the ''VideoGame/MegaManBattleNetwork'' seres also has a buster, but its main firing mode is very weak until it [[MagikarpPower gets upgraded]], so early on it's way more practical to use batle chips. Some battle chips are also fired from the buster.

* At the end of ''VideoGame/MetalGearSolid'', Gray Fox shows up wielding a laser cannon arm; with absolutely no explanation as to where it came from.

* ''VideoGame/MightyGoose'': The titular character has Megaman-style cannons in place of wings, and uses them to blast incoming enemies.

* ''ComicBook/DungeonTwilight'': Red Marvin gets two powerful one with his armor, he can use them as transportation to leap away from trouble and are the only weapon that can hurt Elyacin, the resident {{Juggernaut}}.

* ''Anime/AstroBoy'' in the 2003 series. Before that, he had rocket hands, but rarely used them, as his weapon of choice was instead a pair of machine guns that [[UnusualWeaponMounting popped out of his tush]].
* ''Anime/{{Daltanious}}'s sub-robot Atlaus shoots metal from his arms, and refers to the attack as "Gatling Flasher".
** Remake ''Manga/{{Pluto}}'' also has Gesicht, whose hands turn into cannons (one shoots non-lethal gas, the other shoots a powerful shell). Another robot, North Mk. II, cheats a little by having extra limbs devoted to his weapons.

* ''Franchise/MegaMan'' in many incarnations. All versions justify this by having his arm morph from the cannon to a regular hand.
** Zero has a transforming handheld [[SwissArmyWeapon saber, shield, pogo lance, hookshot, and tonfas]], and a looted energy pistol. It doesn't stop him from using the Z-knuckle to graft enemy turrets and flamethrowers onto his arm, classic-style, in the fourth game.
** And on the subject of ''VideoGame/MegaManZero'', Fighting Fefnir. By extension, Model F users in ''ZX'', which actually falls into the second category. Model FX users just have {{Hand Cannon}}s [[GunsAkimbo Akimbo]].
** In the ''VideoGame/MegaManX'' series, Zero's arm cannon is actually of the second type, emerging from his forearm. He lost his original body at the TimeSkip between the ''X'' and ''Zero'' series, and the so-called Z-Buster is a pistol he grabbed off a dead RedShirt to fight the Pantheons.
** [=MegaMan=].EXE in the ''VideoGame/MegaManBattleNetwork'' series can use an similarly to his ancestors, as well as certain weapon battle chips such as the Cannon, Shotgun, V-Shot, and 3-way. The [=MegaBuster=] itself, however, starts off very weak and lacks the ability to charge its shots [[MagikarpPower until gets upgraded]].

* Brad Fang of ''VideoGame/{{Contra}}: Hard Corps'' has a gun grafted onto his arm which can function as a machine gun, vulcan cannon, or flamethrower.

* The Alien Mutant in ''Film/SlaveGirlsFromBeyondInfinty'' is a hunchbacked alien with a laser rifle for an arm.

* ''VideoGame/{{Bioforge}}'': One of the enhancements that the protagonist got as part of his UnwillingRoboticization. As the weapon is small and concealed, he doesn't even realize it for the longest time.
