Der BiterBot was a heavyweight robot which competed in the final season of BattleBots. It was a blue invertible robot with a front spinning "milling tool". The robot was also splattered with red paint to simulate blood. The team had a story behind this involving a supposedly fictional team member named Bob.
"There was Bob; Bob isn't around anymore."

Der BiterBot did not do that well in battle, losing its only battle to Super Collider.
