It first appeared in the novel as an original labor, and later appeared in the TV series with the same design but with different settings.

In the novel, it is a handmade labor painstakingly built by a father and son at a labor repair shop in town. When the survival game AI installed in it goes out of control, it ends up fighting Ingram with a girl inside. Even though it is AI-controlled, its performance is so high that it can fight Ingram on equal terms. The protruding part on its shoulder is a remote control hand, and there is a scene where it picks up a dropped survival knife. There is a risk of a huge explosion if the tank for the air machine gun on its waist is hit.
