in the first series of Extreme. In its first round battle, Hypno-Disc was placed up against Behemoth, and it was favoured to win. In the battle, the disc of Hypno-Disc couldn't cause any more than superficial damage to the World Championship runners-up, while Behemoth managed to push Hypno-Disc around the arena and into CPZs, even managing to avoid damage from the house robots, after they would always attack Behemoth whenever the competitors would enter the CPZs. Hypno-Disc was overturned by Behemoth at one point in the battle, and got to use its srimech arm for the first time at one point in the battle, but it had a mechanical problem late on in the battle, and was pushed, and left on the flame pit by Behemoth. Hypno-Disc was counted out by the Refbot, and cease was immediately called afterwards. This eliminated Hypno-Disc from the competition. Hypno-Disc returned later on in the series for the Annihilator. It went in, going up against Splinter, Arnold A. Terminegger, Pussycat, Thermidor 2 and X-Terminator. Hypno-Disc was considered one of the favourites to win the whole annihilator, but its performance was similarly disappointing, due to all its competitors ganging up on it. In the first round, Hypno-Disc was immediately flipped by Thermidor 2 before it could get its disc up to speed, and was then continually axed by X-Terminator, Splinter and Arnold A. Terminegger, to prevent the disc getting up to speed at all for the whole battle. Despite this however, Hypno-Disc still scraped through to go through to the next round, due to Thermidor 2 breaking down, and being counted out by the Refbot. In the second round, Hypno-Disc failed once again to get the disc to anywhere near its full speed, and once again it took damage, notably from Arnold A. Terminegger and Sergeant Bash. However, Hypno-Disc had another lucky break when Pussycat knocked X-Terminator's removable link out, immobilising the recent Semi-Finalists. X-Terminator was counted out, flipped by the arena floor flipper, and Hypno-Disc survived to go through once again, although its movement was minimal by the time X-Terminator was fully counted out. Hypno-Disc had so far proved very lucky in the annihilator, however, Hypno-Disc was eliminated in the third round. Although the disc was finally up to speed in this round, just one hit on Arnold A. Terminegger was enough to knock the drive motors out completely, once again. The flywheel was
