Blink: Fannon would likely latch onto her role as head of the inquisition and the way she protects her inquisitors, likely putting her into a mother role or mindset. Common trope will be adopting every kid under the sun. Blink actually doesn't want to mother all these inquisitors but she feels she has no choice as head inquisitor.

Rainy: super aggressive and confrontational over everything. Bakugo from my hero, probably dialed down to a 7 instead of a 10. They'd see her get incredibly defensive over her sister being taken and take that as a default.

Nova: Fandom would probably focus on her high rebelliousness, making her seem more ready to argue against anything on the spot. They'll also make her a lot edgier similar to how the miraculous fandom treated adrien for the longest time.

Diana: Fannon would probably mark her down as overly prideful or vain. They'll villainize her in every high school au, because she's 'better than everyone else' while completely ignoring the fact that that only applies to areas where she knows she's has an advantage, and ignoring all of her development. Either that or they're going to see her as 'Nova's Girlfriend' and that's as far as her fanon personality goes.

Autumn and Aurora: Fandom is definitely going to make these two exact opposites, where Aurora is going to be interpreted as overly negative while Autumn is going to be over the top positive and loud. Both are also going to be slapped with autism and/or adhd and infantilized for it.

Marcus: Tumblr Sexyman. Fanon is either going to wet cat him or make him overly sexy I just know it. They're gonna turn him into Bucky Barnes 2.0 after the second book.
