Hypno-Disc (sometimes spelled Hypnodisc or Hypno Disc) was a competitor robot that fought in Series 3-6 of Robot Wars as well as both series of Robot Wars Extreme. Hypno-Disc was one of the most famous and iconic faces of Robot Wars, and one of the most successful, reaching the semi-finals on four out of four occasions and reaching three successive Grand Finals, the only robot to do so. The Hypno-Disc team consisted of twin brothers Dave and Derek Rose and their father Ken. The Hypno-Disc team's motto was "Spin to Win", a motto soon adopted by other roboteers.
