You will never survive my deadly robo-scorpions, technological terrors and, uh, um... BIGGER, more ATOMIC versions of these things!”— Mobius
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 the escape of the cazadores and night stalkers, Mobius became disillusioned with the methods of the other think tanks. He grew tired of the endless and horrible experimentation, and was deeply afraid of the damage the amoral and psychosis-ridden scientists would wreak upon the fragile, post-apocalyptic world in the name of Science.
Mobius voiced these concerns with Klein and they had a falling out, resulting in Mobius being exiled from The Think Tank; furthermore, Klein removed all the chips of all personalities of The Sink (Mobius' room and personal laboratory) and flung them over the balcony, ridding the Think Tank of all things that belonged to the exiled Mobius. Mobius erected a radar fence – a kind of radar-guided repulsive field – around the perimeter of Big MT to prevent the disembodied brains from escaping into the wasteland.
However, he realized the radar fence would not be enough to keep them in Big MT. So, against their will, Mobius remotely hacked the data banks of his colleagues, reprogramming their chronometers, geometers and cartography programs, making them lose their sense of history, time and the world beyond Big MT to the point that they now believe Big MT is the world and nothing exists beyond its mountainous boundary. He went even further and accessed more personal information, reprogramming their own names to be part of a recursion loop to lock up the Think Tank's processors; he even left hints of this recursion in their new cyclical names. In the process of making these alterations though, he also damaged some of their memories and knowledge, leaving only mangled, disjointed versions behind. Disgusted to have done this to his friends, he also erased some sections of his own memory, like this event and his pre-War creation, the robo-scorpion, before exiling himself. Like the others, he forgot a part of his personality and his real name, due to the recursion loop in their new perception programming.
Afterward, Mobius moved to the X-42 robo-warfare facility (which he dubbed the "Forbidden Zone") and began to "recreate" the robo-scorpion, inspired by radscorpions that had wandered into Big MT. These new versions included all features of the pre-War model, such as an energy bolt blaster in the tail, highly sensitive robotic eyes, and communication systems connected directly to his stronghold. Now in possession of a proper army, Mobius decided that without something to distract the other think tanks, the radar fence would eventually become insufficient to contain them. He began sending repetitive, threatening broadcasts, laced with false notions that robo-scorpions were somehow able to consume intelligence from brains, fueling the Think Tanks' fear of leaving Big MT's central dome. This also served to further distract them from their experiments, as it prompted the think tanks to focus on retrieving technologies with which to defend themselves instead, which kept them occupied and unable to escape the crater. With the remaining think tanks trapped in the central dome by their exaggerated fear of Mobius, the Big MT fell mostly silent.
Although not originally aggressive in his intentions, Mobius' own behavior seems to have degraded over the years, likely in part due to an increasingly serious addiction to Mentats and Psycho. By 2281, his body had become severely damaged, partially rusted, and his right "eye" monitor smashed. He also began to suffer from short term memory loss, hallucinations, and obsessive-compulsive behavior. Although his plan had been ultimately successful, the recent arrival of Father Elijah, Christine, and Ulysses from the Mojave has caused the curiosity of the think tanks to begin pushing beyond the boundaries he had set for them.
The arrival of the Courier, and the subsequent survival of their lobotomy, proved to be the last straw. Mobius unleashed a fresh wave of robo-scorpions and announced his false intention to finish off the other think tanks once and for all. Mobius stole The Courier's brain because it possessed the knowledge of a successful brain extraction, which would be able to replicate the procedure. However, Mobius subliminally suggested to the Think Tank that various technologies around the Big MT would help them against him. These technologies ‒ a sonic emitter, an X-2 antenna, and a Stealth suit Mk II ‒ are actually all the components required to rehouse a brain inside a body and allow the body to leave Big MT. Eventually, the Courier defeated the X-42 giant robo-scorpion, entered the Forbidden Dome, and confronted Mobius.
Interactions with the player character
|This character is essential. Essential characters cannot be killed.|
|This character is involved in quests.|
- Welcome to the Big Empty: Mobius interrupts your conversation with the Think Tank and threatens them with robo scorpions.
- Old World Blues: You are to go to Mobius' lair and either kill him or reason with him.
- He will offer the Courier a Mentat upon interacting with him through dialogue, once per 24 hours.
- If you have consumed alcohol and Mobius asks you if you would like a Mentat you may turn it down saying you would rather avoid mixing it with alcohol.
- If you are already addicted to a drug when he asks you if you want some Mentats you can refuse stating you are tripping as it is already.
Drops on death
- Mobius mixes up a few of his words often. For example, instead of saying reason, quite, and desert, he'll instead say raisin, quiet, and dessert.
- If you say that you "think you're going to kill him", Mobius claims he's never been killed before (obviously true), and that he's eager to see how it goes, obviously keeping to the nature of the Think Tanks. He'll still fight back and summon his robo-scorpion army, though.
- If you enter combat with Mobius, he will activate a Stealth Boy, and it will become impossible to target him in V.A.T.S. However, his monitors will still be active, making him easiy to track. He will also summon several robo-scorpions.
- Dr. Mobius has significantly more health than the other Think Tank members. He also becomes stronger as the player's level increases, increasing in power every 10 player levels. The only other Think Tank member that also increases in power with the player's level is Dr. Klein.
- Although he is at first shown to be the antagonist of the Big MT, he is in actual fact saving the surrounding areas by confining the think tanks to the dome where they cannot perform their immoral experiments on the rest of the Mojave. (Borous alone is responsible for creating cazadores and nightstalkers).
- Mobius programmed the Sink Central Intelligence Unit to accept bottle caps as a debug command.
- You can't yield to Mobius. Your decision to assault him is final.
- Mobius refers to tripping on psycho and Mentats. This can be seen in the upper rooms of the Forbidden Zone dome, which contains both samples of psycho, and an extremely large supply of Mentats.
- He was responsible for the creation of all of The Sink intelligences except for Muggy.
- If Dr. Mobius survives the final Old World Blues quest, the Courier may return to Dr. Mobius and ask for Mentats. Dr. Mobius, through a round about way of speaking, will inform the Courier that more will be available every 24 game hours.
- He has the most damaged and rusted body compared with other Think Tank members.
- "I see you. Now, I end you."
- "I consider "coincidence" to be profanity, along with the words, "astrology," "herbal tea," and "luck." So watch it, Potty Mouth."
- "Mighty Think Tank... still c-c-c-c-cowering in your Dome? Cower, you fools. Cower."
- "Well, there's many things they have forgotten, sitting in their bowls. Friendship. The thrill of discovery. Love. Masturbation. The usual. Much like your brain, I am certain there is something you can spark within each of them. Memories, hormones... ...a wise man once said, the eyes do more than see. Make them see, if you can. Or, if not, you can always make them succumb to fear... it certainly worked for me. For a time. Then you came along, and bravery and/or desperation trumped that little idea. Back to the drawing board, I suppose. Or is this the end? Hard to tell."
- "Oh, a variety of raisins... you're something of a homily. Er, anomaly? You're really quiet special, and not in the cranially-challenged way. You see, you are the most successful brain extraction experiment ever performed here at Big MT. A victim of your own success, as it were. If you were to go back with what your brain knows about the procedure, well... ...your brain could be popped back in and you could walk right out of here. Can't have brains moving around of their own volition." (Mobius on why he stole the Courier's brain)
- "It is I, Dr. Mobius, transmitting from my dome-shaped... dome in the Forbidden Zone. A zone... that is, yes... forbidden to you."
- "In any event, you showed up at the Think Tank, and because you had suffered a cranial injury in just the right place... Bullets in the head are usually much more fatal, and yours was a light case of bullet-head-itis. But... it was enough for the Auto-Doc in the Sink to change its programming to fix the problem. And the brain extraction technology for once, worked. That gave the Think Tank the knowledge its brains shouldn't... couldn't... sh'couldn't possess. With that knowledge, the procedure can be reversed. If they obtain that procedural data, they can use it to mush and modify their cranial selves into hosts to slip past the Radar Fence, I'm sure of it. And once they're off the reservation..."
- "2 plus 2 equals... 4-Bidden, idiots of the Think Tank!"
- "Ah, trying to steal the X-2 Transmitter Array Antenna, are you? You won't succeed, not if my lethal Robo-Scorpions have any say in the matter."
- "Depth perception is a problem with this old monitor of mine. Went black a while ago. That's old age for you. Should look at getting the visual nerves re-attached... it's just that the right eye would see the wrong things. The flying tortoises were the worst. Would you care for a Mentat?"
- "Dr. O... which is actually not his real name multiplied, since you can't multiply his real name in the first place... Ouro-bor-ous, Klein... They have all forgotten themselves. And not only themselves, but the world, sense of time, and history. All that is left is what's here. I reprogrammed their chronometers, geometers, and cartography programs. This is now their world, here, Big MT. It was a merciful lobotomy, really, thinking back. They were my friends, but... sometimes they would take things too far. And the world isn't ready for that kind of too-far-thing-taking. That's my professional opinion, anyway, and I am told I was once quiet professional."
- "Well, every scientist needs an army. Mine came to me after these rather large scorpions kept coming in from the dessert. Like poisonous frosting. How scary, I thought! But they had survived when nothing else had. Perfect candidates for improvement, as a reward for their tenacity. Then I thought, what if they shot energy bolts and acted as walking eyes and data-drained computers and acted as bullhorns? Then I made them bigger. Then, I thought about... custard. I do so love custard. Or was it mustard? Mustard custard. Mmmm. I miss sugars and salts." (Mobius discussing his robo-scorpions)
Behind the scenes
- Mobius was inspired by Dr. Edward Morbius, the antagonist in the 1956 science fiction film Forbidden Planet, as well as the name of his base was inspired by the name of the film. He also references it in dialogue.
- His name is also a reference to the Möbius strip or Möbius Band, a 3D object which topologically has only one side. The challenge to dress in his apparel is also called "Mobius Strip."
- The 'murderous gang of thugs' that he said once went looking for a spine, a heart, and a brain, but had them all along is a reference to Frank L. Baum's book The Wizard of Oz. The thugs refer to The Cowardly Lion, The Tin Man, and The Scarecrow respectively.
- If the player character has taken the Wild Wasteland trait, Mobius will mention keeping several "Plan 9s in place". This is a reference to the cult-classic, 1959 science fiction/horror film "Plan 9 From Outer Space", written and directed by the infamous Edward D. Wood Jr.
- The song Dr. Mobius occasionally sings in his lab ("Electron's attached to the... neutron. The neutron's attached to the... meson. Meson's connected to the... proton") is a parody of the spiritual song Dem Bones, also called Dry Bones.
- If you talk to Mobius after defeating the giant robo-scorpion, you may be forced into killing him, as you can only end the conversation with "enough, I came here to kill you." This can be avoided if the player has a Repair skill of 75, permitting the player to repair the "ghosting" in his optical sensors. This will open up the conversation to leave him be without killing him.
