With almost all of Ulysses Argo's minions being made of metal, keeping them in working order is critical. His Repair Drones scuttle around affecting ad-hoc fixes during battles, deftly welding plates back on or performing quick rewires. Although not designed for combat, their appendages can deal out nasty injuries.
Rules for Repair Drones can be found in the Argonauts Program Guide, or the combined Villains Program Guide book. Miniatures are supplied unpainted and assembly may be required.
