Katnip (sometimes spelled KatNip) was the first featherweight of Cold Fusion Team, although created by Team Kat at the time. It fought and lost in the featherweight competition of Extreme 2 of Robot Wars. Katnip had been created long before its driver, Stuart Barnwell, had had anything to do with Cold Fusion Team, following a competition by Rex Garrod called Rex's Robot Challenge in the magazine Real Robots.
