Special Beam Cannon (魔貫光殺砲, Makankōsappō; English "Light of Death"; Literally meaning "Demon Impaling Light Killing Gun") is an energy wave technique in the Dragon Ball franchise. It made its debut in "Gohan's Hidden Powers", the 4th episode of Dragon Ball Z, which premiered on May 17, 1989. The technique is a vastly powerful laser beam created by Piccolo as a way to destroy his arch-enemy Goku. Piccolo first used the Makankōsappō in the battle against Raditz, killing both him and Goku in one shot. Piccolo uses it in the battle with Turles with little effect.
