X-Terminator

X-Terminator was a wedged box-shaped robot that competed in Series 3 through 7. Its weapons were originally a spiked axe and a front scoop. It also had a pneumatic spike on each side to assist in self-righting. For Series 4, the robot had a flipping arm that could be interchanged with the axe. For Series 5 and 6, the axe was enlargened and the self-righting spikes were replaced with small arms, similar to Behemoth's. For Series 7, the original X-Terminator was sold on eBay and a new model was built with two horn-shaped spikes on the sides. The axe was replaced with a vertical spinning disc with enough power to fling opponents out of of the arena.

In Series 4, the robot was changed from red to silver and was known as X-Terminator 2. Although it reverted back to its original name the following series, a logo reading 'XT2' remained on the side of the machine until Series 6, when the robot was given a new silver and black colour scheme. The new model that competed in Series 7 was painted silver and blue. X-Terminator reached the semi-finals of Series 4 and came 4th overall in Series 7.
