Dr. Who (also known as Dr. Hu) is the main antagonist in the 1966 American/Japanese animated TV series The King Kong Show, and its 1967 Japanese film adaptation King Kong Escapes. He is a mad scientist who desires to capture King Kong for his own evil schemes.
The King Kong Show
Dr. Who is the most recurring antagonist of the show. He is a dwarf, bald, big-brained, and bespectacled mad scientist who wants to capture King Kong to serve his manipulative, blasphemous, and diabolical plans. He often uses giant robots or monsters to fight King Kong, notably Mechani-Kong. Doctor Who tries to destroy Susan Bond by freezing her heart and by sending snakes to stop her. Doctor Who takes Susan's watch and makes a clock snake to defeat and stop Susan. Doctor Who finds Susan and threatens to whip her. Susan starts to try to run away but the evil doctor finds her and starts to whip her.
King Kong Escapes
In King Kong Escapes, Dr. Who is very different from his cartoon counterpart, as he's not dwarf nor bald nor bespectacled. He also seems to be even more sadistic and cruel, as seen when he kills an old man for no apparent reasons.
As in the cartoon, he is the creator of Mechani-Kong, although he has just created him to dig for Element X from the Arctic underground. After his robot has been damaged, he captures the real King Kong and then kidnaps Susan Watson, the only person who can control the giant ape. However, King Kong escapes and swims to Tokyo, with both Mechani-Kong and Dr. Hu in hot pursuit. After defeating the robot, Kong attacks Dr. Who's ship and destroys it. Inside, Dr. Who is crushed by falling debris and is soon killed as the ship finally floods and sinks.
