Context

Trigger: Danny and Taylor get caught in the middle of a fight between Hookwold and the PRT and are torn to sherds; the PRT initially fails to capture the nazi, but when they eventually do he escapes a few times; 'concerned' citizens complain about Annette assigning queer books for her classes, she loses her job; alone and with no pay she loses the house with nobody willing to help her. She triggers her first night sleeping on the streets.

Joining the Undersiders: She starts looking for a building to squat. Finds the Undies' loft and is surprised by them. Lisa mediates and manages to convince Annette to help them out with a job. She sees them as kids in over their heads and, with Taylor's loss still pretty close, accompanies them for their safety.

Personality: Pretty similar to Taylor, just more pathetic, as she's a 40 year old woman that hangs out with teens all day. Let's say that her daughter got her intensity and violent tendencies from her too, not just Danny. Has her daughter's cult leader charisma.

The story progresses pretty much like canon, but without ever planning to betray the undersiders to Armsmaster. Coil's not dumb, so he doesn't reveal the 12 year old in his basement high on opiates. Annete saves Armsmaster, but because she's never contacted him, his endbringer plan is not revealed, so he stays in Brockton Bay. Sophia's not targeted by the Undersiders to carry out their arc 10 job so she reamins in BB too. Lisa still reveals her situation with Coil because she thinks she can take out the boss with Annette. S9 happens(not thought about it, sorry). They take down Coil, Echidna happens. Annette has no life outside of caping, so the identity reveal is pointless and does not happen. Behemoth kills Alec and she freaks out hard, so she immediately goes to kill Heartbreaker with Aisha and ends up with a gaggle of taylor-shaped kids. Time skip, Gold morning, she makes it through (also loses her right arm).

The important part: shipping

She's bisexual and we all know it.

She needs to hate fuck someone. Armsmaster would be a fun choice, but they don't interact at all outside of fights. The other (and better) choice is Miss Militia. Taylor thinks she's super neat and is somewhat parasocial, so let's invert those feelings for Annette who sees her as a government stooge, a chimera made up of the worst parts of the military and law enforcement. Hates her and her 'just following orders' attitude with a passion. Still thinks she's hot. Hates it.

Another fun choice is Sarah Pelham, aka Photon Lady. Both of them dive into capedom as much as they can. Sarah's built all her life around powers for the last two decades, and, after she loses most of her family, dives into it even more. Annette's just lost it and doing the same, just on the other side of the law. Appreciates the ideals of New Wave of transparency and accountability. Closest in age to Annette. Two recently widowed women finding comfort in each other. Could be cute. 'Net will punch your teeth out if you call her Photon Mom instead of Photon Lady (even before meeting her). Also, Crystal's reaction would be fun.

Faultline, Lisa walks in on them fucking, takes 30d6 of psychic damage.

Annette does not turn herself in, so she doesn't meet Alexandria like Taylor did. IF she did, though, Lexie's hot and 'Net looks close enough to Contessa, so they fuck and never speak about it.

Armsmaster still gets visited by Mannequin and becomes Defiant. He and Dragon do some unicorn hunting, maybe.

Number Man reminds her of young, blond Danny. Finds him hot, that's it.

Jack Slash, thinks he's hot, hates it. Instantly clocks him as gay .

Marquis, thinks he's hot, hates it. Instantly clocks him as bisexual .

Other relationships

Chastity's about the age Taylor was when she died, and looks somewhat similar, so she gets really attached to the 13 year old Vasil. Tries teaching her some feminism when she catches her talking about her worth as a girl for the first time. Finds her relationship with Cassie cute.

Aisha hangs out with Annette a lot because of the heartbroken. Encourages her to read and learn at her own pace. Accommodates her learning, even if she's not sure if Aisha has ADHD or something else.

Lisa's her number one hype woman, Annette's her sopping wet adult, who is scary when she needs to be and praises her intelligence

Talks taxes and budgeting with Brian, who thinks she's the coolest woman ever (not that he's talked to many older women, or girls his age).

Rockier start with Rachel than Taylor. As she does not ever plan to betray them and Armsmaster cannot reveal that, she still manages to help her out like Taylor did. Rachel still starts her settlement in Gimmel with her people and ends up in a similar place to her canon counterpart.
