Doctor 0

Doctor O is a Think Tank member operating in the Big Empty in 2281.

Background
Doctor 0's scientific specialty is in deconstructing robots. He also has an excessive hatred of Mr. House and built Muggy with the intent of mocking House's Securitrons.

Upon dialogue with Dr. O The Courier discovers his name is Dr. 0 (Zero) and everybody has been reading his name wrong.

Quests

 * What's In A Name?: The player must have 9 Intelligence and/or the Math Wrath perk in order to help him with his name problem. The PC will suggest adding a slash through the zero to differentiate between a zero and O.

Behind The Scenes

 * James Urbaniak also plays the voice of Dr. Thaddeus S. "Rusty" Venture of the animated show The Venture Bros. Doctor O's name may be a reference to Dr. Byron Orpheous, a character from the show.
 * A second reference to the Venture Bros. may com from Doctor 0 (Zero's) name and the fact that Rusty Venture, try as he might, is never successful in being a super scientist, just like Doctor O.
