|"I was hoping to save it for a special occasion, it's the attack I planned to use to defeat you."
— Piccolo to Goku, preparing to use the Special Beam Cannon against Raditz, in "Piccolo's Plan"
Special Beam Cannon or accurately referred to as the Makankōsappō (魔貫光殺砲; lit. "Demonic Piercing Light Murder Gun") is an energy wave technique in the Dragon Ball series, and is one of Piccolo's signature attacks, along with the Explosive Demon Wave. The technique is a very powerful laser beam created by Piccolo in order to destroy his then-arch-enemy, Goku.
