Dr. Who is the most recurring antagonist of the show.

King Kong Escapes
Hideyo Amamoto played Dr. Who in the live action film. The character 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 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.
