Terrorantula was a heavyweight robot which competed in Season 5.0 of BattleBots. It was a rather complex robot, using four omni-directional wheels for movement enclosed inside spiked wheel guards. These wheel guards could clamp together on both the front and rear ends of the robot using pneumatics, and the robot was armored on both the top and bottom with two gigantic spinning circular saw blades. Terrorantula did decently in competition, winning one battle before losing to Ringmaster.
Terrorantula was originally being built for Season 4.0 and named X-Terminator, but it was not finished in time for the competition.
