The CombatBot was a very advanced and expensive robot designed for combat in the frontline of a battlefeild. It had very thick armor plating and was capable of fighting more than five enemies at once. It was first tested in an alien base, where it successfully wiped out all the aliens at the station on its own. On its way to be mass produced, other prototype robots aboard the cargo ship experienced an error and started attacking everything in sight. The CombatBot survived and later entered mass production and remained in service until 2117 A.D.
