Chaos 2 was a wedge-shaped robot armed with an extremely powerful pneumatic flipper. It was armoured in aluminium and polycarbonate. It was a very successful robot, winning two series of UK Robot Wars in a row, the only robot to do so. It also had the honour of being the first robot in UK Robot Wars to flip another robot out of the arena, (over the arena wall) doing so to Firestorm in Robot Wars: The Third Wars. Chaos 2 is also capable of doing this in some of the games it appears in. Chaos 2 is one of only two robots, itself and Pussycat to appear in all five of the Robot Wars video games.
