Whether he's fighting giant bugs in the school's basement, rescuing cats from trees, or making the perfect spaghetti sauce, Machine Boy is always looking for the best way to help others. But when his heart begins to interact dangerously with other debris from space, Machine Boy wonders if he can be a power for good after all.
