The Guts Tank (also known as the Guts-Dozer) is a massive robot tank created by Dr. Wily that appears as the boss of the third Wily stage in Mega Man 2. Its design is clearly based on Guts Man.

The Guts Tank has no weapons, but will constantly spawn Metalls from a hatch in its torso. Mega Man can stand on the flat surface at the front of the tank base and fire upon the robot's head. Atomic Fire inflicts the most damage on this boss.
