I've got one which I'm surprised hasn't been mentioned yet - Spikasaurus.

All right, it might have got battered in the Northern Annihilator, its armour wasn't the most resilient, it could be flipped easily and its spikes didn't sound like they offered much of a threat even by Series 4 standards. But it had 3kW of drive power, enough to turn it into the robot equivalent of a raging bull (sorry Terror-Bull) and to allow those spikes to pierce Stinger, Suicidal Tendencies, Killerhurtz and even the wall with ease. It had self-righting rollbars which worked reliably when they weren't flattened. It survived to a Judges' decision in its only UK Championship battle, becoming the first of only a few robots to puncture Stinger's tyres in the process. It stood up to every axe blow Killerhurtz, Dominator 2 and Shunt could land on it in the Northern Annihilator, the very same competition which saw Chaos 2 and Stinger eliminated as a result of said attacks. As far as I'm aware, Spikasaurus never broke down on its own accord, either - the closest it came to doing so was when its batteries were running out in the Northern Annihilator final, but Dominator 2 had already bitten the dust by then.

In short, Spikasaurus may not have been quite as dominant or as precise as something like Tornado or Spawn of Scutter, but it still emerged as a worthy Annihilator champion through its speed, spikes and staying power.
