Supervisor Greene is an olive green Mister Handy model robot with a personality modified into that of an archetypal game show host. He, along with the two other supervisors, White and Brown, have much more advanced cognitive processors than the typical Mister Handy as well as distinctive personalities derived from the favorite television show characters of their creator, Dr. Edward Gray. Greene offers limited merchant services akin to a general goods trader.
Greene will attempt to reward the Sole Survivor with a "brand new" car, although will instantly offer a "cash prize" of 100 caps instead. Passing a speech check can increase the reward to 150 caps, another speech check increases it to 200 caps, then a final speech check can increase it to 300 caps.
Greene is a general goods merchant. It can also be assigned to specific merchant stalls if those are built at Graygarden; although it will not move to the location, still offers their full inventory.
Greene will almost always be found tending the settlement's mutfuit orchard, and will from time to time engage in conversation with the other supervisors.
↑Supervisor White: "The worker drones carry out labor and maintenance. We supervisors - that is, myself, Greene and Brown - possess sophisticated cognition processors. We are capable of complex analysis and decision-making, a testament to the genius of our creator, Doctor Edward Gray." (Supervisor White's dialogue)
↑Supervisor White: "Perhaps you've noticed that I possess a rather singular personality, as do the other supervisors." Sole Survivor: "Why did Doctor Gray give you these unusual personalities?" Supervisor White: "Genius is restless, darling. It abhors stagnation. Doctor Gray was tired of the standard Mister Handy personality. He looked to his favorite television characters for inspiration, and we are the result." (Supervisor White's dialogue)
