Deep Digger

Deep Digger (ディープディガー) is Uranus's special weapon from Mega Man V. This weapon can only be activated when Mega Man stands on top of certain square-shaped blocks, which he can pick up and throw forward in a straight line. Blocks that can be thrown will change color when Mega Man comes into contact with them. If a thrown block hits an object or wall, it will break into four smaller pieces that will ricochet in the opposite direction. The floor of Terra's lair is made of Deep Digger blocks; accordingly, this weapon is his weakness.
