Angus MacGyver's most frequent opponent, a master assassin who never fails—except when MacGyver gets involved. Murdoc is an accomplished pianist, master of disguise, as well as highly skilled and creative in the use of booby traps. He is also very fond of heavy weapons, including flamethrowers, bazookas, and dynamite. Murdoc's signature for each hit is to take photographs of his victims at the moment of their deaths. MacGyver first encountered Murdoc in 1980: Murdoc was being followed by Peter Thornton, and MacGyver comes to Pete's aid. Their interaction convinces Pete to hire MacGyver to work with him at the DXS.
