Leighviathan was robot that competed in Series 2 of Robot Wars and was the successor to the Series 1 competitor robot Leighbot. It was over 3kg over the Heavyweight limit at the time. Like the team's previous robot, Leighviathan progressed steadily through its heat, even holding its ground to house robot Dead Metal, only being beaten by eventual heat winner Mace in the Heat Semi-Final. Its name was a pun on the word leviathan. Presently, Chris Malyon is working on converting Leighviathan into an autonomous snowplough.
