G.B.H. (stylised as GBH on the robot) was a competitor in Series 2 and Series 6 of Robot Wars, entered by Team On-The-Edge, known as Team Joint Effort in Series 6. After reaching the Series Semi-Finals in The Second Wars, it was retired in place of Facet. In Series 6, the team returned to Robot Wars with GBH 2, which started promisingly but was eliminated in a close Judges' decision in the first round. The team now consisted of Mike Smith, his son Alex, and Steve Dove, formerly captain of the Challenger team, who also drove Eubank the Mouse in Series 1. He and Mike Smith had been work colleagues.
