- "That weapon's a vertical 20kg spinning disc, but they have other problems, exposed wheels, light armor and the fist could be a little limp-wristed."
- — Jonathan Pearce
Doctor Fist was a silver axle-shaped robot, which was compact and invertible, the machine was armoured with a 3mm welded aluminium chassis. It was armed with a 20kg vertical spinning disc spinning downwards at 2000RPM at the front powered by two 5HP petrol engines.
However, not only did Doctor Fist suffer from having exposed wheels and light armour, it was beset with problems in Series 6 as one of the engines did not work to drive the disc. The drives would also prove to be unreliable in its New Blood heat, ultimately costing it the battle.
In its one and only battle in the main competition, Doctor Fist faced Dantomkia, Mr. Nasty and Crushtacean, where it barely moved at all during the battle. It drove to the side of the arena and then broke down. Dantomkia then came in and rammed it a couple of times, tipping it onto its side. Little happened to Doctor Fist after this 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.
