These toys had moving weapons and, in most cases, a pullback motor, meaning they would move forward on their own once pulled back along the ground. When first released, the pullbacks were usually priced at £10 apiece and always came with accessories. For example, obstacles from the Pinball arena and football tournament. Some of the toys are quite fragile, with X-Terminator 2's axe often being bent, and Chaos 2's flipper often refusing to retract. The weapons were activated in many different ways, such as pressing a button to activate a flipper, or by simply running a robot's front wheels along the ground to utilise a spinning disc. The Firestorm and Wheely Big Cheese pullbacks were notorious for having two small front wheels which were not present in real life, thus decreasing any effectiveness the weapons had.
Two robots did not have pullback motors: Stinger, activated using a ripcord, and Sir Killalot, who used a friction motor.
The Phase 1 house robots (and Hypno-Disc) came with interchangeable parts, such as Hypno-Disc's rear armour and Matilda's chainsaw and flywheel. Parts that weren't on the actual robots included the hammer with Sir Killalot and the top of his lance with Dead Metal. Later, the Phases 2 and 3 robots didn't have interchangeable parts apart from X-Terminator 2 and Tornado.
