Pollux Assassin Droids were rather taller than a human, and somewhat resembled Super Battle Droids in size and physique. They had an angular humanoid chassis, and lean faces, dominated by four red photoreceptors beneath a sharp, swept-back crest. Although their primary function was the assassination of specific targets, these droids typically fought in sizeable teams, overpowering their targets with firepower and combat skill rather than stealth. They seem to have been used sparingly, and on both their recorded front-line deployments, they were sent against groups of Jedi at the direct command of the most senior Separatist commanders.
