Makankōsappō (魔貫光殺砲) - Special Beam Cannon, Light of Death or (literally) Demonic Penetrating-Light Death-Cannon.
A powerful beam attack created by Piccolo as a way to destroy his then arch-enemy Goku. Piccolo first used the Makankōsappō in the battle against Raditz, killing both him and Gokū in one shot.
The move is performed by touching the index and middle fingers of one hand to the forehead and charging enough energy to attack. When ready the fingers are extended forward, the attacker shouts the name of the attack and a thin curly-cue like ray of energy is released. The resulting beam is quite powerful, drilling through most targets, and exploding on the ones it can't. The main disadvantage of the attack is the time required to build up enough energy for the focused burst.
During the battle with Nappa, Piccolo used a blast with a similar appearance, though he fired it differently (both hands fully outstretched) and did not have to charge it up.
In the anime, Piccolo uses it additional times when battling Garlic Jr. and as a mental projection created inside Buu's mind. Gohan also uses a very similar move while practicing with Krillin (in a mental battle) on the way to Namek.
Additionally, it is used by Cell twice, the Cell Juniors, and later by Buu after he absorbs Piccolo. Because this skill is chosen in combat so much, whether by Piccolo or someone else, one can assume that it is among the best techniques to use.
In the non-manga uses of this move, the charging time is much shorter, though the resulting blast is seemingly much less powerful.
