So will Jade faced princess ever be mentioned in your au? Since LMK kinda goes "Don't trust history" I like to imagine she was just Red's babysitter and people assumed she was a mistress
Oh man I went down a fox-hole with this. I find her potiential as a character so good for the LMK verse. She could be a villain, an ally, a general, or in my personal fave idea: Ultimate Auntie. (One of my fave interpetations is by @harveylikestoart).
So my idea for Princess Jade Face / Jade Faced Princess / Yu Mian Gongzhu is this:
Birth name is Ruan Yu (soft jade/nephirite), but goes by Jade to her friends, and Auntie to anyone she deems younger than her.
Appearance wise: she's a humanoid fox spirit/Huli-Jing with dark green hair, pale skin, and big green eyes. Loves wearing really old fashioned long-sleeved hanfu that trail behind her (mostly to shield her tails without glamour), and is hyper-feminine. Wears obnoxiously patterned cheongsams while out and about.
Has a "feral" form of an eight-tailed dark green fox. She mostly shifts into this form for comfort. Think of the shapeshifter equivalent of taking off your bra after work.
She's a minor royal of a big family of fox demons. Same family as Jin & Yin's (+ Lin the accountant's) mom actually! She likes visiting them whenever she's in the city.
Knew DBK long before the Brotherhood days. They were childhood best friends in the Underworld who got mistaken for a couple a lot (cus "a guy and a girl can't just be friends" obvs /sarcasm). When PIF came along, Jade was one of DBK's biggest hypemen.
Her dynamic with DBK and PIF is essentially an older Traffic Light Trio, with her as the Mei. Green coded, high energy, and adored mutually by the others.
Because of her chill nature and hyper-fem style, people assume she's dumber than she actually is. She plays up her more "Barbie" qualities when she's tricking people/gaining information.
She's ridiculously good at handling babies and toddlers since she grew up with so many little nieces/nephews/niblings. When baby Red got fussy, a little visit from Auntie Jade immediately perked him up.
Wasn't an "active" member of the Brotherhood back in the day, but was a big supporter and intelligence gatherer. She almost got charged with treason after Sun Wukong's imprisonment, but PIF covered for her - despite their first impressions not being so great. She offically left the Brotherhood after Princess Iron Fan and Demon Bull King's engagement.
Was really sad alongside PIF and DBK when Red Son/Boy got taken to the Southern Seas by Guanyin to rein in his emotions. The "affair" mentioned in JttW wasn't an affair at all, but a human misinterpetation of how DBK was helping out his homie emotionally. Jade never forgave the writer for branding her as DBK's mistress.
Is extremely doting and embarassing to Red Son even when he's an adult. She's practically his second mother. Cheek pinching, calling him "kit", saying that he needs to eat more food, sharing baby photos with his friends etc...
The "Jade" in her name is not only a reference to her dark green hair/fur. Her family are Rock/Earth-type demons. She was so good at handling Red as a baby since fire doesn't bother her as much. She also owns a fox mask made of literal jade that she wore back in the Brotherhood days to hide her identity she thought looked mysterious and dramatic.
Doesn't have an actual spouse or biological kids of her own. She's happy being the best unmarried Auntie she can to all the kids.
Will def appear later in the "Monkey King and the Infant"-verse as Red's fave Auntie. Once PIF has "picked up" (read: kidnapped) Red back from the Southern Seas, Jade is immediately called in for babysitting backup.
She and Macaque became friends again on accident while working at the theatre together. She's part of the costume and makeup department, and it took them a few crossed paths to finally recognise one another. She is def partially to blame for Red's flair for dramatics.
Has a particular grudge against Zhu Bajie for whacking her with the rake. Has a nasty scar that starts on the back of her head down to her shoulder blades from the fight. Was extremely cold towards Pigsy before she realised (very embarassed) that he was just Bajie's decendant.
Initially disliked Sun Wukong when they reunited, but quickly it became clear that the the two's more loud, reckless natures bounced off one another. Are rivals for the title of "Best Babysitter".
Spoils baby MK and the other kids rotten. Doesn't matter if the baby is a mystic monkey, dragon, cat demon, human, or demon bull calf; baby is baby.
Takes an obscene amount of luggage with her no matter where she goes. Is "hairdryer in her purse" kind of prepared.
Yips when she's excited/happy. Also chirps in response to Baby MK's monkey chirping. The language crossover of fox and monkey sounds is surprising.
Voice claim: Diane Morgan/Philomena Cunk. She has a softer British accent compared to her related demon niblings. Red Son may or may not have developed his accent from her.
Gosh I love weird women characters.
