- "Will this demonic machine drive through its rivals and skittle them?"
- — Jonathan Pearce
Demon was a very basic box-shaped robot, painted yellow with a front shunting wedge that bore a devil's face, steel ramming spikes at the rear and a very low top speed of only 2MPH. The low speed was because the motors came from an indoor wheelchair, which were less powerful than outdoor wheelchair motors.
In the Gauntlet, Demon crawled out of the starting gate, and dived into the Sentinel route as the sphere came rolling past. As Demon tried to dodge The Sentinel it was pinned against it repeatedly by Matilda, sustaining damage from the chainsaw. Despite this Demon pushed Matilda towards the End Zone, before turning and being shoved perilously close to the pit. After just about escaping that, Demon turned and spun past Matilda and Sir Killalot, before eventually squeezing into the End Zone.
In the King of the Castle trial, Demon again tested its pushing power as it was immediately caught by Dead Metal, taking punishment from the circular saw. The House Robots nudged it towards the edge although Demon withstood the pressure, before Sergeant Bash came in with a charge and took both itself and Demon off the ring, giving it a time of 27.47 seconds.
Demon came up against The Mule in the Semi-Finals, withstanding early aggression and lifting from Roger Plant's machine. The Mule shoved Demon towards the PPZ, until Demon fought back and shunted The Mule into the PPZ itself. Despite this, Sir Killalot came in and attacked Demon as it had become immobilised. As the fight came to a close, Sir Killalot tried to drive up the front of Demon. The fight went to the Judges, but they ruled in favour of The Mule.
