Mad Drill

Mad Drill is a Mechaniloid that appears as an enemy in Mega Man X5.

Mad Drills attack with their drill coming in and out of the wall that they are attached, and even though the drill hitbox is surprisingly smaller than the drill sprite, the attack is an instant kill. They are stationary and can't be killed. They appear in Grizzly Slash's stage, in the middle of the second section of the level, where players need to reach the other side before the trains explode.
