Moira is a supporting villan in the videogame Overwatch.

Biography
Moira O'Deorain waves when she published a controversial paper detailing a methodology for creating custom genetic programs that could alter DNA at a cellular level. It seemed like a promising step toward overcoming diseases and disorders and maximizing human potentialfor science and the advancement thereof however, unlike Mei and Winston, who are both bright-eyed individuals with altruistic motives for their respective researches, and unlike Mercy, who puts the lives and feelings of others before her, Moira doesn't have much in the way of limitations when it comes to how far she'll go in her experiments. She's tested on animals, she's tested on herself, and it was only through the involvement of Blackwatch - and later Oasis and Talon - that she was able to continue her research unimpeded.

In game, Moira gives an air of superiority,  somewhat oddly for a villain in Overwatch, she seems to take either a neutral or positive stance towards Omnics (though this sentiment is shared by fellow Talon member Doomfist to an extent), as she reflects upon London's "medieval" attitudes towards them when she first spawns in King's Row occasionally.

Jeff Kaplan describes her as "weirdly self-obsessed more than anything" and has a thirst and hunger for knowledge and she doesn't really care about the outcomes of her scientific decisions. He also jokingly described her as "chaotic neutral" which originates from D&D Alignment.
