Mr Nasty was a competitor robot that entered Series 6 of Robot Wars as well as the New Blood Championship in the second series of Robot Wars Extreme. It did not enjoy great success, being eliminated in the first round in Series 6 and losing to Mute in the second round of the Extreme 2 New Blood Championship. Following the introduction of the active weapons rule in Series 7, Mr Nasty was unable to take part, and thus did not return following these appearances.
