Zipman!!

When a brilliant but somewhat unhinged scientist creates the ultimate combat robot, he expects to be hailed as a genius. Instead, his creation is deemed a failure, leading him to an unexpected, tragic end. But death is rarely the end of the story, especially when a devoted, if slightly less intelligent, twin brother is involved. Determined to honor his brother’s legacy and prove his genius to the world, the surviving twin takes a drastic step: he merges with the robot, becoming a new kind of hero. Now, as the unlikely fusion of man and machine, he must navigate a world he barely understands, fighting to protect the innocent and fulfill a promise made beyond the grave.
