Able to take the form of powered armour, small mecha and other light walkers, the mimic is a very much unwelcome suprise when it reveals it self. Shadding its assumed form to reveal powerful Swarm beam weapons in the midest of a formation is often desisive.
It is thought that the Mimic's main function is recone but it has proven adept as fullfiling commando or specal forces type rolls.
