Robot statistics correct as of its most recent appearance on the show
Doctor Fist was a competitor robot in Series 6 and Extreme Series 2 of Robot Wars. It was an unusually shaped robot, compact and invertible, with a 20kg vertical spinning disc spinning at 2000RPM at the front powered by two 5HP petrol engines. The machine was armed with a 3mm welded aluminium chassis, but was beset with problems in Series 6 as one of the engines did not work to drive the disc. It also suffered from having exposed wheels and light armour. Doctor Fist was eliminated in the first round of both Series 6 and the New Blood Championship in Extreme Series 2.
Doctor Fist only moved slightly in its battle. It drove to the side of the arena and broke down. Dantomkia then came in and rammed it a couple of times, tipping it onto its side. Little happened to Doctor Fist as Mr. Nasty had also broken down and Dantomkia was focusing on Crushtacean. Eventually Refbot counted Doctor Fist out and Dantomkia flipped it back onto its wheels. Sir Killalot then came over and tried to pick Doctor Fist up, but failed to do so. Instead Sir Killalot pushed Doctor Fist into the pit just as Mr. Nasty was pushed down by Sergeant Bash.
Doctor Fist fought in the last of four New Blood heats in Extreme 2. In its first round, Doctor Fist faced Piranha and Fatal Traction. While the other two robots attacked each other, Doctor Fist was busy losing the drive in one of its wheels and spining round in cirles by Refbot. The House Robot pushed it back into the action, where it continued to spin in circles. This was all it did for a while, until it was shoved onto the flame pit by Refbot. Its petrol engine burned, and Mr Psycho suddenly approached it and hit it with his hammer before ripping its drive wheel completely off. Matilda then hit it with her flywheel twice, and Refbot counted it out. This made Doctor Fist the only veteran robot to lose the first round.
