These are some ideas featuring superheroines and young hapless men or women they "date" in a someone toxic but still sweet imbalanced relationship:

1. You're in love with Carol Danvers, Captain Marvel. One day she rescues you from an alien attack and takes you to her place. There, she takes your virginity and decided to temporarily move in with you since you're recovering and your family is traveling. This will be a cutesy budding romance tale with her acting as a caretaker. Or maybe it starts that way but gets a little darker over time...

2. Power Girl protects you from some dangerous criminals and takes you to a safehouse while she hunts them down, because they want to hurt you. As she keeps you there, she starts developing feelings for you, getting super clingy and protective, keeping you isolated and with no electronics. Maybe one day you catch a glimpse of the news and see she's already taken care of the criminals and she's just keeping you for herself!

3. Wanda is still grief stricken and looking for a family to rebuild. when she sees you, she takes you to her town and turns you into her perfect adult child, to take care of on her own. Of course, mother gets lonely sometimes...

4. Harley Quinn is feeling lonely, so what better way to fix that than to break out of Arkham and kidnap a young nurse to turn into her son or daughter and jokerize!

Celebs would be their big screen performers, but open to switch it up: Brie Larson, Elizabeth Olsen, Margot Robbie. Bryce Dallas Howard, Mylana Vyantrub, are some others I like, the latter being a potential Power Girl, or Squirrel Girl as she was supposed to be

Open to other heroes (and villains) and scenarios! Main kinks for this would be mommy kink, fake incest, tit play, breath play, rimjobs, milking, controlling woman, toxic relationship (optional), deepthroat, power/size imbalance. Open to darker kinks too

Here is a sample:

"My day was dull and boring, having to go through meeting after meeting on avoiding collateral damage, and discussing the latest threats to the planet. Yawn. I have never been one for talking about plans and ideas, I'm more of a get it done kind of person, no matter the side effects. Who cares if some people complain? Without us, no, without me, this planet would have been eradicated ages ago. So what if during my last mission some building got destroyed? No one died, and the one guy that was injured is getting better. He's at my place, I'm personally nursing him back to health. And I can't wait to get back home to him... To you... I really hope you don't ask me about seeing your fiancee tonight. I need a calm sweet night. Won't you be a good boy and do that for me? You wouldn't want to make mommy angry, now, would you?"
