Command Flynn is in charge of the Military Security branch of Gravia Technologies. She’s competent and cold, level-headed, but also fair and concerned with the safety of her troops. She almost never raises her voice, and inspires immediate confidence in those around her. 

Much of her dialog in the game is in the form of pre-recorded training messages that aid the player throughout the game, though she does appear in a number of scenes in-person.

Flynn’s accent is flexible, but whatever the accent, she should sound like a strong, military leader type.  She isn’t a dislikable character, but she’s cold and unforgiving, and I expect most players to somewhat dislike her, like you might dislike a very strict instructor who never gives any positive feedback. But she isn’t “mean”, just precise and efficient.
