Demolisher (also known as The Demolisher in the first series) was a featherweight robot that took part in the first and second series of Robot Wars. Weighing in at just under 3kg, and with dimensions of only 60cm by 36cm, it was easily the lightest and smallest robot ever to compete in the main competition of Robot Wars. Despite this, it reached the Heat Final in Series 1, losing to Cunning Plan, and won the Featherweight Championship shown as part of the Grudge Matches episode of Series 2, although the latter was not fully shown on television.
Demolisher did not return after this, as the Series 3 Featherweight Championship was cancelled. However, it later attended the Series 4 qualifiers, winning a match against Firestarter after constantly driving around and ramming it.
Demolisher was frequently used in Robot Wars media, featuring in the VHS release of Robot Wars: The First Great War where Derek Foxwell demonstrated the inner workings of the machine, making several appearances in Dr. Zulu's column in the Robot Wars Magazine, as well as its appearance at the Series 4 qualifiers in what may have been an exhibition match.
Demolisher was based on a radio-controlled car, and featured a welded aluminium shell with a front-mounted wedge intended to get underneath opponents and topple them over, although this was made more difficult because of its small size. Its shape also allowed it to roll back onto its wheels easily if it was flipped over.
Demolisher was also remarkably fast with a reported top speed of 40mph, making it the fastest robot in Series 1 and one of the fastest in the show's history. However, its small size, control issues (to the point that it even comically crashed through the arena railings during its introduction) and the fact it could be overturned fairly easily hampered Demolisher during its only main series appearance.
Demolisher zipped through the Gauntlet seemingly quickly, but was placed third on the leaderboard, as it had overturned mid-way through the course. However, this was not seen on the televised show.

Demolisher performed equally well in the Stock Car trial, immediately taking the lead due to its massive speed advantage and completing two whole laps. However, on its final lap, Demolisher clipped the outside of Sergeant Bash's plinth, overturning it and allowing Cunning Plan to cross the finish line in first place. Cunning Plan subsequently pushed Demolisher over the line, putting it through to the Arena stage, although Demolisher's performance would have still been good enough to allow it to progress anyway.
Demolisher redeemed itself in its Arena Semi-Final battle against SAT'arn. The two robots pushed each other around until Matilda intervened, cutting through SAT'arn's body with her chainsaw and stopping short of cutting into Demolisher as it got wedged in between.
This intervention put Demolisher through to the Heat Final against Cunning Plan. In what became the quickest battle across the first two series of Robot Wars, Cunning Plan used its wedge to topple Demolisher over straight away, eliminating it as Demolisher had no means of self-righting.

Demolisher later took part in the Series 2 Featherweight Championship. In the final, Ripper never moved more than a few centimetres due to an uncharged battery. Then, Anarchy, built from an old RC car, was defeated before Demolisher turned on Armadillo, far outpacing the opponent. Demolisher was briefly overturned, but the House Robots re-righted it, with Demolisher landing on its wedge side and escaping before it could be flipped again. Demolisher spent the remainder of the fight pushing Armadillo around the arena, winning the subsequent judges' decision and the Featherweight Championship.

- Demolisher is one of 23 robots to have completed The Gauntlet, and one of only 3 featherweights to do so (alongside Cunning Plan and SAT'arn.
- Demolisher, along with Wharthog, was among the few robots to transition from the main heavyweight competition into a smaller weight category. It is also the only robot to have successfully won a championship in that division.
- Demolisher's loss to Cunning Plan became the quickest immobilisation and the shortest battle for a number of years.
- Demolisher was the first robot to suffer a Self-inflicted immobilisation.
- Demolisher is the lightest robot to have competed in the main series of Robot Wars to date.
- In Dr. Zulu's column in the Robot Wars Magazine, he is pictured pulling a pile of wires from the base of Demolisher.
