Questionable Questing

How to change his clothing and manner. What does being a Femboy do for his life?

I don't want to say that Bakugo has any deep rooted insecurities, but he has for lack of a better word hole in him he's have trouble wrapping his head around. He wants to be a hero. He wants to be the best. He wants to be strong and powerful, but he doesn't really know why. He doesn't have some deeper meaning to it all, no one to save or no goal or adversary to beat.

It's part of the reason he hates Deku so much. Here's this guy with a goal, a grudge, a world full of enemies. someone who has every reason to fight and bleed for everything and he didn't do shit for basically all his life until he magically got a powerful quirk. For Bakugo that just pisses him off more than anything, that it took getting a quirk for Deku to start fighting back.

Miss Robbin fills his bussy and gives him purpose in service to someone who likes him. Not for being a hero but for being a violent asshole

Bakugo's a guy who's pissed that he doesn't really know what exactly he wants, yet he's surrounded by people who know exactly what they want and they've known their entire lives.

And like you said Miss Robin can give him a purpose.

Purpose in what? Being a sex slave alone ain't good writing. What does she give him uniquely by owning him?

She helps open up his world if that makes sense. He's always felt confined and controlled, like he didn't fit or that there was something wrong with him for being as competitive for wanting to fight as much as he does, and Miss Robin can show him a world where that's allowed.

She can either help him embrace the villain lifestyle or show him a brand new type of hero the world needs and some very evil villains that deserve it. He can finally fight and hurt and maim without feeling guilty or out of place.

How so? And how that feed into a ravenously slutty fem baukugo?

Justified supported violence

Bakugo doesn't feel like he fits as a normal hero. He doesn't like the costumes or the speeches, or the how cheesy and fake it all seems. he wants something real, he wants blood and guts and to fight on the ground against the real evils of the world. And the femboy aspect ties in with this because in the process of discovering the real kind of hero he wants to be, more Rochach or punisher than Superman.

Bakugo also discovers that he likes dressing and presenting himself a certain way. That he enjoys doing things that are seen as feminine. Basically a big part of Bakugo's internal struggle is a lack of identity and being a slutty femboy is a way for him to explore that. To do crazy things and see how he feels about them without any shame or judgement.

But what does Bakugo consider femine? Pink and girly is out. He'd want something provocative and seductive and dangerous

I don't want to go with the street walker look entirely, but that's the vibe I'm going for. Bakugo doesn't see that as his ideal form for femininity, but rather he's doing super exaggerated and crazy things because he wants to explore how he feels about it. Think of it like someone who's been super repressed finally having an outlet.

I've suggested punk before for Bakugo

That works pretty well. I was actually thinking of Rebecca from Cyberpunk in terms of personality and design.

Tattoos and more red and orange for colors as it fits Bakugo?

Bright clothes too. Piercings, lots of leather mixed with overly cute things like scarfs or charms.

Not very pink.
