I Own the Zombie Queen

In a post-apocalyptic wasteland, Robert, a top mechanic betrayed and exiled to the dead city, awakens the Mechanical Dominator System. With his infinitely evolvable mecha dogD.O.G., he builds an invincible underground fortress. He forcibly tames Anna, an S-class AI zombie queen sent to assassinate him. Relying on overwhelming firepower and mecha combat strength, he crushes hypocritical human forces and the zombie leader Alpha, rising from a desperate outcast to the mechanical king dominating the wasteland.
