Stinger

Stinger was a robot with a large spiked mace on the end of an arm. The arm was designed to swing around whenever the driver reversed the motors. Stinger had virtually no body; all the electronics were within its two large wheels. Stinger entered in Series 3, 4, 5, and 6. In Series 3, a grinding wheel (or pizza cutter, as described by fans) was used instead of the mace, but the old Stinger was far too difficult to control, bouncing off Mace II and driving into the pit.

Stinger was a surprise entrant to the 4th wars. It had gotten the number 30 seed based purely on its popularity, but surprised everyone with its aggressiveness and potential. It disposed of newcomer Hammer & Tong in its first one on one battle, then continued to the Semi Finals, meeting Panic Attack. A controversial judges decision saw Stinger move through to the Grand Final, much to the chagrin of many of the audience members, who believed that Panic Attack had done more. Meeting Chaos 2, Stinger proved very aggressive again, breaking the case from Chaos 2's back, but the judges ruled in favor of Chaos 2.

They couldn't enter Series 7 because of a new rule that stated that every robot must have a moving weapon.
