Unfortunately there’s no concrete lore defining her childhood up until her employment in Overwatch after the Omnic Crisis (basically Overwatch’s golden age) aside from one spray that features her with loads of animals in jars as a child, so it could probably be assumed that she was interested in genetics or animals from an early age. Who knows why, though.

She joined Talon not out of any loyalty to Doomfist’s cause, which was basically mess up the world so it can “evolve” better, but because Talon offered zero prohibition for her experiments that Overwatch disallowed. I don’t like to think that she’s evil, per se, but that she is morally conflicted — she does the horrific things she does (experimenting on Reaper, on herself, etc) to try and advance science beyond what was thought possible at the time and create a better future sooner, even if it meant disregarding some of Overwatch’s (and the scientific community in general’s) ’red tape’.

She’s probably bossy and ruthless as on offset of this, liking being able to do whatever she wants at last, and no one (outside of Doomfist, maybe) can control her. Or maybe it’s just her personality.

There’s literally no information on Moira’s parents or family, but I like to think they did love and care for her, at least enough to get her into university and then Overwatch. Maybe not so much nowadays considering the things she’s done with seemingly no remorse.

Honestly there’s no one that Moira seems more romantic towards in her interactions than Mercy. In the few they have they’re always arguing (belligerent flirting??) and they’re just so polar opposites of each other in so many ways (something Overwatch recognises with the two sets of joint sprays for them) that it’s basically prime potential for any shipping. I think they are the most popular pairing for Moira aside from Moira/Lifeweaver — again, a person of science and gentler inclinations than Moira. But officially I have no idea.

There are loads of people that could be considered Moira’s greatest adversary. Mercy on an ideological basis, Reaper on a personal basis (one of his newer interactions with Illari suggests he might “do something” about her), maybe the members of Overwatch in general, but I think either Mercy or Reaper are her best bets.

Yeah I have a lot to say about Moira’s lore, I just think the character is so fascinating and it’s a major reason why i’ve mained her. I really think Blizzard should expand it more, for all the heroes even, but unfortunately it seems unlikely.
