Berzerker 2000 was a heavyweight robot that fought in Seasons 2.0 and 4.0 of BattleBots built by a group of students from the University of Oklahoma. It was a circular robot armed with a spinning tire with attached flails and two triangular wedges. Berzerker 2000 was not very successful, losing its only battle in Season 2.0. After this loss, the robot was revised, named The Bevo Blender, and entered by a completely different team for Season 4.0. It still couldn't win a battle, and the robot was retired afterwards.
