Demolisher

Demolisher was a competitor from the first series of Robot Wars. Weighing in at just under 3kg, and only reaching a maximum size of 60cm by just over 35cm, it was easily the smallest robot ever to compete in the main Robot Wars competition (although other, significantly smaller and lighter robots would later fight in their own tournament). Based on a toy racing car, Demolisher was a small box with a wedge on the front. The intention was to use the wedge to get underneath its opponents and topple them over, although its size made this task difficult. Its shape also meant it was easy to roll back over on its wheels if it was flipped over.

Despite its size, some control issues and the fact it could be overturned fairly easily, Demolisher made the heat final of its heat, losing to Cunning Plan. Although not fully shown, it also returned for a special Featherweight competition of Series 2, which it won.
