I reject all existing versions of fem!Derek, so I made my own
Lore of fem!Derek aka Dakota Goffard:
• Yes, she has short hair. It used to be long, but she cut it off as a protest against her mother’s demands. She got in trouble for that and was sent to a stylist to "fix" the length. Since then, she’s kept it short – she thinks it makes her look bolder, more daring.
• Like the original Derek, Dakota isn’t particularly athletic due to her sweet tooth and overall hedonistic streak, so she’s got softer curves. Her mother strictly controlled her diet and would scare her by saying she’d "turn into a fat cow" if she ate too much. As a result, Dakota now has something akin to an eating disorder.
• Unlike Celia, she has zero solidarity with women. If anything, she hates them more than men, and gets irritated whenever she finds herself around a girl who’s slimmer or more talented.
• The previous point stems from this: up to a certain age, Dakota was able to maintain contact with her father (who later mysteriously "disappeared"), and he wasn’t nearly as cold as her mother. Deprived of maternal affection, Dakota unconsciously competed with her mother for her father’s attention, which resulted in her developing an Electra complex (Freud's theory). Because of this, she sees all women as rivals, and tends to use men for her own ends – manipulating them and leveraging her sexuality to get what she wants.
• She likes Komodo's trinkets and she’s planning to knock someone’s teeth out so she can make a necklace of her own.
