Dr. Fung

 is an elderly Chinese doctor residing in San Francisco's Chinatown. He wears a white smock, matching his wizened appearance and is one of the best physicians in the wastelands, capable of replacing organs, implanting battle armour plating and general healing.

He taught Dr. Holliday of Broken Hills.
