Doctor Klein

Doctor Klein is a pre-War scientist operating the Big Empty in 2281.

Background
Doctor Klein is a pre-War doctor and the administrator of Big MT. Sometime after the Great War, he became a think tank to continue his work at Big MT. He seems to be overconfident in his intelligence, as evidenced by returning all of the advanced technology and the Courier having to walk him through the plan for the next quest, as he couldn't figure out what to do.

Strangely, although being human at one point, he does not seem to have much knowledge of human anatomy, as he refers to the Courier's fingers and toes as "penises". He is shown not to like Mobius much although they were partners at one time. He seems to hold his colleagues in low regard, often ignoring their advice. At the end of Old World Blues, it is revealed that he and the think-tanks stole the Courier's brain in order to go into the Mojave and conduct ruthless experiments on both the Wasteland and its denizens much like the implementation of the Cloud in the Sierra Madre to test the chemical, Hazmat suits and Auto-Doc technology.

Behind the scenes

 * His name is a reference to the Klein bottle, a 4D non-orientable object.
 * The three perks that he can give the courier (Heartless, Brainless, and Spineless) are references to The Wizard of Oz: the scarecrow was missing a brain, the tin man was missing a heart, and the lion was missing courage.
