Jonathan Pearce continuously referred the robot as "the purple pyramid", though it was painted blue; the team's previous robot was purple.
Cyrax was a roughly pyramid-shaped in design. Its main weapons were a electric-powered pickaxe on the back and a small rear-hinged flipper on the front. Both weapons were reasonably effective and the robot has a low ground clearance of 1cm, but its armour was thin. A flashing light appeared on top of Cyrax.
Cyrax's first battle of the Sixth Wars saw it in a potential grudge match with Team Tetanus, whose previous robot Flip Flop Fly controversially beat the team's previous robot Wild Willy, as well as Ruf Ruf Dougal and Weld-Dor 3. Cyrax started strongly, assisting Tetanus 2 in disposing of Weld-Dor 3 before it was pitted. Cyrax repeatedly buried its axe into Ruf Ruf Dougal and tried to lift it, before the dog's fur eventually caught fire. Cyrax kept away from the potential grudge Tetanus 2, and survived until the Judges' decision, where its aggression throughout the match allowed Cyrax to progress with Tetanus 2.
Cyrax had the misfortune to be placed against reigning champions Razer for the second round match. Razer started by trying to crumple the front flipper of Cyrax before managing to drive it into the jaws of Growler, who pushed Cyrax the length of the arena before letting go. Razer then managed to grab hold of a corner of Cyrax's pyramid shell and hold it in place while Mr. Psycho hit the robot twice with his hammer which knocked off part of the lense cap of the blinking top light. Cyrax responded by flipping Razer over but Razer managed to self-right and put one last hole in Cyrax before cease was called. The judges eliminated Cyrax, based on the large amount of damage sustained as well as poor driving and lack of aggression.
