Background
Doctor Mobius was one of the Big MT "Think Tank" executives before the Great War. Sometime after the War, he became a think tank in order to continue his work at Big MT. After a dispute with Doctor Klein, Mobius removed all the chips of all personalities of The Sink and left, settling in the X-42 robo-warfare facility, or Forbidden Zone. He is the inventor of the Robo-scorpions that surround the facility as well as all of The Sink intelligences, except for Muggy who was created by Doctor 0.

Other interactions

 * If the player character has a repair skill of 75, this allows them to repair the "ghosting" in Mobius optical sensors. This will open up the conversation to leave him be without having to kill Mobius.
 * If the player character cannot perform the 75 repair check, they will be forced to kill Mobius, as the conversation can only end with "enough, I came here to kill you."
 * He will offer the Courier a tin of Mentats upon interacting with him through dialogue, once per 24 hours.
 * If one has consumed alcohol and Mobius asks them if they would like a Mentat, they may turn it down saying that they would rather avoid mixing it with alcohol.
 * If one is already addicted to a drug when he asks them if they want some Mentats, they can refuse, stating that they are tripping as it is already.
 * Once combat is entered, Mobius will activate a Stealth Boy, this making it impossible to target him in V.A.T.S.
 * Dr. Mobius has significantly more health than the other Think Tank members, and along with Doctor Klein is the only Think Tank that levels with the player character.
 * The player character cannot yield to Mobius. The decision to assault him is final.

Mobius 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 Mobius' appearance designed after Dr. Morbius from Forbidden Planet.
 * If the player character has taken the Wild Wasteland trait, Mobius will mention keeping several "Plan 9s in place" which is a reference to the film Plan 9 From Outer Space.
 * The Wizard of Oz is referenced by both a line of dialogue and a script note in Mobius' dialogue.
