Gerbilov was a lightweight robot that competed in Season 4.0 of BattleBots. It was a full-body spinner which used a vacuum-formed lexan shell attached to a thick metal ring as its main weapon. Unfortunately, it lost its only match to Dracolich and never appeared again.
Gerbilov only fought Dracolich. Right off the bat, Dracolich slammed Gerbilov hard into the wall, and then almost totally stopped moving. Gerbilov backed up and spun up, then hit the near-lifeless Dracolich. However, it only suceeded in killing itself. Dracolich moved on.
