(Update) It's far, far more than 20 Chaos Drones now
20 drones made by Scrapmetal called Chaos Drones. They are the Chaos Contingent's version of Autotroopers, pretty much. They take orders from the Chaos Contingent only, and not questioning them. They are equipped with various weapons, but always keep two mini-missile launchers. They transform into futuristic cars.
