Guts Tank (ガッツタンク Gattsu Tanku?), also known as Guts-Dozer, is the boss from the third Wily Castle stage in Mega Man 2. It is a large tank based on Guts Man's design, that resembles an enlargened version of Guts Man's torso with spiked shoulders and caterpillar tracks instead of legs. He releases projectiles from his mouth, and Mets exit from the opening on his chest. Mega Man can stand on his treads to reach his head, the only part of his body that receives damage.
