Doctor 8

Doctor 8 is a pre-War acoustician operating the Big Empty in 2281.

Background
Doctor 8 is a pre-War doctor who became a think tank to continue his work at the Big Empty. He has lost the ability to talk due to damage sustained to his voice module during an encounter with another visitor, most likely Elijah. Instead, he transmits RobCo sound waves, which appears in subtitles as patterned RobCo terminal symbols. However, after passing a high Science check or a Perception check, the player seems to understand his language without altering the subtitled text.

Quests

 * On The Same Wavelength: Though there is as language barrier between the player and Dr. 8, you can still communicate with him Perception of 7 or a Science skill of 75.

Appearances
Doctor 8 appears in the Fallout: New Vegas add-on, Old World Blues.

Behind the scenes

 * His collection of clocks (seen in his home and his room in the Think Tank) may be a reference to Doc Brown from the movie "Back to the Future", whose home contained 60 clocks in addition to a large audio amplifier.
 * His name is a reference to infinity, as the number 8 an infinite loop. This is featured in a conversation with Doctor Mobius.
 * His name may also reference a possible obsessive-compulsary focus on the number 8. In his home, you can see 8 coffee cups, 8 clocks, 8 photos, etc.
