Hypno-Disc was the first UK competitor robot to be turned into a pullback. It featured the horizontal flywheel of the real robot, activated by moving the pullback forward/back, as the front wheels axle connects to the flywheel. The rear armour was interchangeable, allowing the user to attach the spiky rear end of the Series 4 iteration (without the srimech), or the plain armour of the Series 3 version, this armour also featured the srimech. Underneath the armour plates was a small representation of Hypno-Disc's innards.
It has the wheels from the Series 3 version, but the tyres on them can come off and are easily lost. The pullback's flywheel is based on the series 3 version of Hypno-Disc, as it has the same type of teeth seen on that model (one on the edge of the flywheel, one on the top). A pitstop and a minibot were also released.
Difference from real life
- Of the two shells featured with the toy,(the series three one, and the series 4 one (with the spikes)) the srimech is found on the wrong one (the series 3 one)
- Despite being based upon the series 4 version of Hypno-Disc, it features the series 3 wheels.
- The disc on the model is the series 3 disc, with one thin blade.
