What are some of your headcanons of Vanica in a neutral or good au, how do you see her interacting with your faves, not counting Grey. Mostly thinking abour Black Clover but anything is good, also ofcourse Vani and Grey are flirting/fightflirting in the background of this.
Good question! I guess I technically have a neutral/good AU already in We'll Write Our Own Stories, but we'll focus on the main Black Clover universe.
She is, of course, still Vanica. She would probably end up in the Black Bulls because no other squad will take her on account of the fact that she's insane. What this means is that she is going to enable Luck's behaviour and make him worse, and if he's not fighting Magna then he's fighting her (which makes Magna jealous and sparks a rivalry). She's also probably going to be crazy about Noelle again once Noelle learns Sea Dragon's Roar onwards (much to Noelle's chagrin). Finral will probably have some sort of crisis once Vanica's with Grey because how come VANICA can pull a woman and he can't?! He tries to get pick-up tips from her and she doesn't even know how she did it, so that's no help. Also, even Finral doesn't try to pick up Vanica while she's still single. He knows when to quit, he's not into crazy - in fact, he is very very afraid of her.
Sometimes people from outside the squad get Vanessa and Vanica's names confused. Vanessa is also often patching up her clothes because she keeps damaging them in fights. She also gets into spats with Zora because she thinks he's boring because his traps don't kill people, and Zora takes offence to being called boring. She also does not care about animals so she pays zero attention to Nero and only gets interested once she turns back into a person and has Arcane Stage magic (Vanica likes all the Arcane Stage mages because of course she does, they're strong, how else did she end up with Grey).
Vanica really loves Asta's Anti Magic but finds Asta himself annoying because he yells a lot. She also teams up with Magna for initiating newbies so basically all the newbies are terrified for their lives and Yami has to ban her after she almost kills somebody. I'm not entirely sure if she remembers Gordon and Henry even exist, although Henry crushing his foes with the whole house is very much a highlight, and she is mildly intrigued by Gordon's curses but otherwise never pays attention to him. She also keeps deliberately provoking Charmy into fights by snatching her food so that Charmy will go apeshit (Charmy would kill her if she wasn't a squadmate).
Gauche finds Vanica annoying, because he finds everyone in this squad annoying, but because he's Grey's friend he often has to interact with her so refrains from trying to kill her for Grey's sake. As for Nacht...
Nacht absolutely LOATHES Vanica. He hates this whole squad but she is top of his shit list. Part of Grey's reason for standing up to him is to defend her (which she of course finds very hot). Meanwhile, Vanica calls him things like "buzzkill" and "killjoy" because he's boring and won't let her have fun (he said she's not allowed to kill people). Even after Nacht officially rejoins his squad, he and Vanica maintain a mutual disgust for each other and deliberately don't interact a whole lot.
She also keeps getting into trouble with Captain Yami. In the beginning, it's because Vanica won't stop menacingly flirting with the stronger people the squad fight and that's not helpful (like what she did with Lolopechka and Noelle in canon). But after she's entered a relationship with Grey, she stops the flirting and instead gets in trouble for toying with and harming opponents more than necessary. The worst part is that she won't tone it down when HE tells her to, but she MIGHT (it's not guaranteed) if Grey asks her to, to which Yami asks her "who do you think is the captain here?!"
Speaking of Grey, I know we're generally excluding her from this ask, but I'll note that in this timeline she and Vanica would probably start dating after the Spade Arc, which is when Grey reaches the height of her power and finds out she's Arcane Stage. It just makes sense. I might make a separate post to further explore what the timeline of their interactions/relationship looks like in a Black Bull Vanica AU because now I'm intrigued. If I end up starting ANOTHER WIP because of this, I'm blaming you 💙🖤 (just kidding, I could never be mad about more writing)
