"With licensed stealth technology, so undetectable by enemy radar, … quickest in the field at 40 miles and hour, and also the smallest, at an itsy-bitsy 60cm!"
Jonathan Pearce introduces The Demolisher

Demolisher (also known as The Demolisher in Series 1) was a featherweight robot which 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 UK Championship. Despite this, Demolisher reached the Heat Final in Series 1, losing to Cunning Plan, and won the Series 2 Featherweight Championship, although the latter was only partially shown as part of the end-of-series special, The Grudge Matches.

Demolisher did not return after this, as the Series 3 Featherweight Championship was cancelled. However, it later attended the Series 4 qualifiers, winning a friendly match against Firestarter after constantly driving around and ramming into it.

In addition to its aforementioned appearance at the Series 4 qualifiers, Demolisher was frequently used in Robot Wars media. It was featured in the VHS release of Robot Wars: The First Great War where Derek Foxwell demonstrated the robot's inner workings, and made several appearances in Dr. Zulu's column for the original Robot Wars Magazine.

Demolisher in Series 2

Demolisher was based on a radio-controlled car, and featured a welded aluminium shell with a pair of ramming spikes at the rear, and 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.

Robot HistoryEdit

Series 1Edit


The Demolisher speeds away to complete The Gauntlet

The Demolisher zipped through the Gauntlet seemingly quickly, but was placed third on the leaderboard, as it had overturned mid-way through the course by bumping too hard into Sergeant Bash. Matilda then uprighted The Demolisher and allowed it to finish its run. However, this was not seen on the televised show.

"That's taking the Michael!"
Jonathan Pearce on The Demolisher's swift Gauntlet performance

The Demolisher lies overturned in Stock Car

The Demolisher performed equally well in the Stock Car Race trial. When activate was called it immediately toppled itself after crashing into the first corner behind SAT'arn and Cunning Plan. Fortunately, The Demolisher was flipped back over with assistance from the latter, and it quickly took the lead due to its massive speed advantage and completing two whole laps. However, on its final lap, The Demolisher clipped the outside of Sergeant Bash's plinth, overturning it once again and allowing Cunning Plan to cross the finish line in first place. Cunning Plan subsequently pushed The Demolisher over the line, putting it through to the Arena stage, although The Demolisher's performance would have still been good enough to allow it to progress anyway, since Krayzee Tokyo broke down near the end of its first lap.

Matilda's chainsaw begins its descent

The Demolisher redeemed itself in its Arena Semi-Final battle against SAT'arn. The Demolisher began defensively, as it dodged SAT'arn's initial charge. The Demolisher then whizzed round the arena, before SAT'arn chased it down and spiked it, and then pushed it into a CPZ. Then as The Demolisher escaped, SAT'arn suddenly broke down in the centre of the arena. The Demolisher attempted to spike its opponent, but Shunt drove in, pushing and almost overturning The Demolisher, but survived, and then it joined Shunt in ramming the immobile SAT'arn, until Matilda intervened. The house robot cut through the body of SAT'arn with her chainsaw and stopping short of cutting into The Demolisher as it got wedged in between.

This intervention put The Demolisher through to the Heat Final against Cunning Plan. In what became the quickest battle across the first two series of Robot Wars, with The Demolisher starting tentatively, Cunning Plan closed in slowly and then spurted forward, using its wedge to topple The Demolisher over straight away, eliminating it as Demolisher had no means of self-righting.

"It flipped over in the Gauntlet as well..."

Series 2Edit

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. Next, Anarchy, built from an old RC car, was soon defeated as Demolisher gave it a mighty slam, before it turned on Armadillo, far outpacing the opponent. Demolisher was then briefly overturned, after driving onto Armadillo's lifting tail, but Matilda and Sergeant Bash re-righted it, with Demolisher landing on Armadillo's sloped side, and escaping before it could be flipped again. Demolisher spent the remainder of the fight pushing Armadillo around the arena, at one point onto the arena floor spikes where Armadillo struggled to escape, and was pressurised by the House Robots. Demolisher would go on to win the subsequent judges' decision and the Featherweight Championship.

  • Demolisher is one of 23 robots to have completed The Gauntlet, and one of only three 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.
  • The Demolisher's loss to Cunning Plan in Series 1 became the quickest immobilisation and the shortest battle for a number of years.
  • The Demolisher was the first robot to suffer a Self-inflicted immobilisation, turning itself over during both of its Series 1 Gauntlet and Stock Car runs.
  • The Demolisher is the lightest robot to have competed in the main competition 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.
