Robot statistics correct as of its most recent appearance on the show
Maximus was a wedge-shaped robot. It fought exclusively in the New Blood Championship of Extreme 2, losing in the second round to Roobarb. It could run at 15mph and was armed with a spinning disc and a flipper that become a front 'shield' when locked into position. The team claimed the disc to be three times as powerful as Hypno-Disc's, spinning at a maximum of 18000RPM.
Maximus faced Mr Nasty and Niterider in its first battle. From the off, Maximus was caught by Mr Nasty and shoved around the arena onto the arena side wall. Mr Nasty shoved it several more times, activating the pit in the process, before being shoved onto the flame pit. Refbot then examined Maximus, who wasn't moving itself, but its flipper still was, so Refbot moved over to the immobile Niterider and counted it out. While the House Robots attacked Niterider, Mr Nasty pitted the now fully immobile Maximus, but both were through. Next, Maximus faced Roobarb. Roobarb began by lifting Maximus and tipping it over. Maximus tried to self-right but was only able to do so with Roobarb's help, balancing on its own flipper. Roobarb then flipped it again, this time onto its side, before trying to flip it out of the arena, but was only able to right it. Maximus drove into a CPZ, was attacked by the House Robots, and immobilised. Shunt put the fallen robot onto the Drop Zone, which dropped a cooker onto Maximus. Mr Psycho finished the battle with a blow from his hammer.
Maximus was technically one of four robots to come back to life whilst being counted out by the Refbot. Though it only moved its weapon, this was still enough to convince the Refbot that it was still mobile.
