Master Driller's hero costume consisted of a maroon-colored suit. His legs were covered with metal protectors. His left arm sported a metallic armband and forearm guard, while his right was a huge drill. From the little that had been seen of his personality, Master Driller had proven to be a person of great courage and resolution, determined to help his fellow heroes when they were in danger and to fight to the end, even if it costed him his life.
