Jim Struts was a walking robot that competed in the Reserve Rumble at the end of Robot Wars: The Second Wars. The first walkerbot to ever appear in Robot Wars, it also became the first to win a battle, emerging victorious in the Rumble after all of its opponents became immobilised around it. As it only competed in the Reserve Rumble, Jim Struts is one of the few robots to have never lost a televised battle, a feat which was later repeated by its successor, Miss Struts.
