Doctor 0

Doctor 0 is a pre-War scientist operating in Big MT $$

Background
Doctor 0 is a pre-War doctor that became a think tank to continue his work at Big MT. Doctor 0's scientific specialty is in robots, both in construction and deconstruction. He also has a large hatred for Mr. House and his founded company, RobCo Industries. As a result, he built Muggy with the intent of mocking House's Securitrons. He also recognizes the Pip-Boy latched around the Courier's left wrist and would have forcefully removed it out of spite, if he still had hands.

Upon dialogue with Dr. 0, the Courier discovers that his name is not Doctor O, but Doctor (Zero), and everybody has been reading his name wrong.

Effects of player's actions
If the Courier has helped out 0 with his name problem, and they do not have a 100 in Science or 85 in Medicine to convince Dr. Klein alone, 0 will side with the Courier in convincing Klein to back down.
 * If the Courier passes Barter skill checks during their initial dialogue with the Think Tank, he will give them 50 caps upon request once per day.

Appearances
Doctor 0 appears only in the Fallout: New Vegas add-on, Old World Blues.

Behind the scenes

 * Chris Avellone stated that according to Brian Menze, the Think Tank members are depicted (left to right) as Dala, O, Borous, Klein, 8, and Mobius on the Old World Blues intro slide.
 * With the Wild Wasteland trait, one of his broadcast messages across the crater will be "Attention: Lobotomites. Do not neglect to wash the walking eye." This is a reference to an episode in The Venture Bros when Dr. Venture is seen washing the walking eye in front of a gathering crowd.
