Drill Man

Drill Man (ドリルマン Doriruman) is a Robot Master originally created by Dr. Cossack to dig in construction sites. When Dr. Wily forced Dr. Cossack to work for him, Drill Man was converted into a combat robot to fight against Mega Man in Mega Man 4, basing himself deep underground, in a mine shaft. Similar to Crash Man, Drill Man has no hands. Instead, he has two powerful, all purpose drills made for grinding through solid rock and earth, which he incorporates into his attacking strategy- burrowing into the ground to avoid attacks, before leaping up from underground to ambush his foes. His Special Weapon, the Drill Bomb, is a powerful explosive with a built-in drill, launched from his arms to pierce into dense objects or armor, before detonating inside of them to cause the maximum possible damage, akin to the Crash Bomber, Crash Man's weapon. His weakness is the Dive Missile, which can trace his heat signature and home in on him (although the games claim that rock can block his signature).
