Donald Hark

Donald Hark is PMT's first agent assistant. He helps Harold with his (Harold's) missions.

Harold The Spy
Donald was assigned to be Harold Douglas's assistant during the case of the Vine Street Shootings. He seems to be better at making decisions than Harold, but Harold thinks he has authority over Donald. In a deleted scene, he is promoted to a full agent.

Harold The Spy 2
Donald Hark was planned to reappear in Harold The Spy 2, but the film was ultimately canceled and Donald was replaced with a new character in Harold The Champion.
