Dr. Who

Doctor Who is the antagonist in the 1967 King Kong film King Kong Escapes.

History
Doctor Who runs a nondescript, presumably criminal, enterprise. He plans to use Mechani-Kong and King Kong to mine the powerful Element X for an undisclosed country to make nuclear weapons with. After his initial mining attempts fail due to Element X's magnetic waves causing Mechani-Kong to break down, he begins to rebuild the robot. Operations continue until he hears of the real Kong's discovery on Bono Island, and decides to kidnap him instead. When Kong is in custody, Who implements hypnosis to control the gargantuan ape. For a short time all goes as planned, but the rays emitted by Element X caused the control apparatuses to malfunction, and Kong to awaken. After this, Who captures his former colleague Carl Nelson and Nelson's team. After initial noncooperation, Who locks them in a cell in his base in the Arctic. Who begins to torture his captives, but they are saved by King Kong's escape from captivity, which causes the base to collapse. Who spares no time in relocating to his boat. Who shortly decides to chase King Kong, who has gone to Tokyo, with Mechani-Kong to destroy him. Kong later destroys Who's boat, killing him and everyone else in it.
