History Characters / Fallout3Megaton

* QuestGiver: He gives you the quest "The Power of the Atom" on your first or second time talking to him.

[[/folder]]

* BigSisterMentor: Mixed with SinkOrSwimMentor (see below), but much her Moira's dialogue and voice-acting heavily implies that she views the Lone Wanderer as a [[LikeBrotherandSister surrogate younger sibling]] to her. Constantly speaking to them with a doting and encouraging tone. [[spoiler:Plus, a hallucination of her corpse during the Point Lookout MushroomSamba moment implies the feeling may be mutual.]]

* BunnyEarsLawyer: While she is an absolutely kooky MadScientist of a woman who has wild assumptions about certain things and excuses every crazy and dangerous request by saying it's ForScience, she is ''genuinely'' very smart in terms of intelligence, as her SPECIAL stats can show with her INT at 7, and it's the main reason Megaton puts up with her eccentricities. And a lot of the things she does, like healing you from ''near-dying'', cleansing extreme amounts of radiation (benign mutation aside), and the processor widget that allows all the robots in the [=RobCo=] Facility to be reprogrammed display it. She is also, despite her almost naïve optimism, one of the ''very few'' characters in the Fallout Universe who understands and has accepted that there's simply ''no'' going back to how things "used to be" before the war, and that all humanity can do is try and make the best of what they have now and use the pieces of what's left to make something new, which is one of the main drives behind her making the guide.

* {{Foil}}: To Grayditch's Doctor Lesko. Both are eccentric scientists whose approach to the scientific process leads the Lone Wanderer to dangerous places, but while Lesko has no concern for how wildly dangerous his experiment is, setting up right in the middle of a developing town, Moira at least sends her research assistant far afield, ensuring that if anything goes wrong, only one person gets hurt.
** In addition, Moira's Wasteland Survival Guide is a project with a clearly defined process and end goal (send someone out to brave the wastes in order to determine the best way to survive out there, then distribute that knowledge to as many people as possible). Lesko's research is unfocused, slapdash and arguably pointless (inject FEV into ants and hope they'll get back to their Pre-War size, when most everyone agrees that giant ants are a nuisance that can be held off with a pistol).

* MadScientist: A lighthearted and humorous take on the trope. Moira is genuinely trying to improve the wasteland, but her "experiments" reach into this trope. Her terminal entries, for instance, include wondering if Brahmin heads learn independently, if Centaurs can talk, if explosives can be used to expand the town, and if Mole Rats can be domesticated (which actually is [[HilariousInHindsight Hilarious In Hindsight]] considering how in ''New Vegas'', the Mole Rat "Snuffles" is the town pet of the NCR mining town Sloan). There's also this quote after the radiation part of the guide quest:

Megaton is one of the more stable settlements around, with about thirty people, a sheriff, a water purifier, scavenging teams, and a wall to keep Raiders out. However, there is the little problem of [[BreadEggsMilkSquick an unexploded atomic bomb in the middle of the town]], but hey, it keeps those nuts at the Church of the Children of Atom occupied, [[TemptingFate so how bad can it be?]] When the Lone Wanderer arrives, Megaton's fate can be decided. However, both ''New Vegas'' and ''4'' reveal that [[NoCanonForTheWicked that canonically]], Megaton survived the events of ''Fallout 3'' and [[CuttingOffTheBranches has greatly expanded in influence]] as [[EarnYourHappyEnding both one of the most populous cities in the Capital Wasteland]] and the origin of the [[BigBookOfEverything Wasteland Survival Guide]].

* BigGood: Despite her oddities and foibles, her driving motivation behind her actions is to become one of these for the entire Wasteland, courtesy of publishing the definitive guide on how to survive in a post apocalyptic world, and seeing how the guide [[VideoGame/FalloutNewVegas has gotten as far as the Mojave Wasteland in just four years and boosts the Courier's survival skills]], [[NoCanonForTheWicked it seems that the Lone Wanderer canonically helped her extensively in her research]].

* CowboyCop: {{Subverted|Trope}}. While he does dress up as a cowboy, he's much closer to a ByTheBookCop. For example he knows Burke is up to no good in town, but until he actually does something besides look and act suspicious he won't take action.

* ReasonableAuthorityFigure: He's a nice guy with good morals and firm patience, and despite the player walking in with no real idea what is going on, he helps explain some things about the town simply to help. You could make fun of him all you like, and insult his town, and he merely shakes his head and warns you to behave.

* ColdSniper: He normally isn't even accessible to the player character due to his location. If the Lone Wanderer ever manages to reach him he'll tell them to leave him alone so that he can watch for raiders.

* HateSink: One of the more despicable characters in the game overall thanks to his infamous Jerkassery. Many a player will go out their way to kill him secretly ignoring the karma penalty.

A cranky old man who serves as Megaton's best (and only) doctor. Most players have a strong love/hate relationship with him, they hate his guts and annoying comments but love his stimpaks and medicine. The fact that he is one of the only easily accessible medics for the early parts of the game is a good enough reason to keep him around, otherwise he'd likely end up face down in the irradiated water surrounding Megaton's warhead next to Cromwell after his first introduction.

* BigSisterMentor: Mixed with SinkorSwimMentor (see below), but much her Moira's dialogue and voice-acting heavily implies that she views the Lone Wanderer as a [[LikeBrotherandSister surrogate younger sibling]] to her. Constantly speaking to them with a doting and encouraging tone. [[spoiler: Plus, a hallucination of her corpse during the Point Lookout MushroomSamba moment implies the feeling may be mutual.]]

* RetiredMonster: Similar to Flak in Rivet City he used to work for the slavers in Paradise Falls, though to what extent he supported them and how far his help actually went remains vague.
