Psychosprout was an unusual spherical robot that competed exclusively in the first series of Robot Wars. At the time, it was a Middleweight. It was entered by father and son team Chris and Toby Marsden, and reached the Trial stage, where it was eliminated. However, its spherical design enabled it to receive the first Most Original Entry award at the end of Series 1. The Boy Sprouts were originally expected to take part in Heat F of the First Wars, but were transferred to Heat E, which forced Psychosprout to take part in a Trial that was less suited to its design.
