Shark Tooth was a middleweight robot built by students from California State University Long Beach (also referred to as Long Beach State or CSULB Robotics) which competed in the 2009 BattleBots Collegiate Championship.

One of the more unusual and heavily-armed designs to appear, it was a black and silver robot with two-wheel drive, a low box-shaped chassis and a multitude of spinning weapons. Alongside a pair of drums at the back, Shark Tooth featured a row of five circular sawblades on a centrally-mounted assembly over its top panel.

Shark Tooth initially received a bye into its first scheduled match against Cattitude - previews for which featured in the first and so far only publicly-released episode.[2] Official BattleBots records confirm that it lost to Cattitude on a Judges' decision, but redeemed itself with victories over JailBrake and Bear Punch in the Loser's Bracket. Though Shark Tooth would again be defeated shortly afterwards, this time by the University of Miami's Category 5, its recovery ensured that it finished the Collegiate Championship fifth overall with a 2-2 record.[3][4]

Shark Tooth gets kicked in the air by Cattitude

After receiving a bye into the second round of the main Winner's Bracket, Shark Tooth's first matchup was against Cattitude. Brief highlights of the battle showed it to be kicked up in the air by Cattitude's drum spinner at one point. Shark Tooth would survive the full three minutes, but lose on a Judges' decision.[3]
