Grab Buster, known as Snatch Buster (スナッチバスター Sunacchi Basutā?) in Japan, is Mercury's special weapon from Mega Man V. When Mercury uses it against Mega Man, he can steal weapon energy, Tanks and P-Chips. Mercury can also fire it diagonally. When used by Mega Man, it sends a shot straight forward that can steal energy from the enemy to heal two units of health. Pluto and L. Knuckle and R. Knuckle are weak to this weapon. With the exception of these three and Brain Crusher's second form, all other bosses are immune to this weapon.
