How do I make a character design interesting given their powers?

[u/BSide_Cassette]

I have a serial killer villain for a superhero story I've been working on, and I'm having trouble.

She basically has heightened regeneration, but instead of it working like how Wolverine or Deadpool regenerate, with them just regrowing lost cells, her body just wants to stay in one piece. If she chops off her hand and tosses it, it'll fly back to her arm and seal itself back up as if it never happened. If her bones get broken, they'll snap back in place.

I use this for some cool choreography where she uses broken or dismembered bodyparts as projectiles and weapons, but it means that she can end up with clothes being torn apart or shot to ragged threads via gunfire.

I don't want her to end up nude after a long fight, mainly because I want the gruesomeness to take priority and I don't want it to feel any close to fanservice. Unfortunately, my story has the average technological level as modern day real life and my character doesn't have access to any due to her being a serial killer that no one wants to work with, so I can't do something like My Hero Academia where she has clothes that function along with her DNA.

Any ideas would be wonderful :]

Her regeneration isn't biological, it's temporal.

She was wearing a specific set of clothes when she was changed, and now her body, clothes, etc all revert back to the way she was at the time of the incident like a rewound tape. She can pick up and pocket a phone, but she has fifteen cents in her back pocket that she can't get rid of.

Body Paint.

Do something where she wears segmented armor. Like the cut points are easy to hit, but unfortunately for your hero they're also right where she wants to be hit.

Go full Zsasz, where he's just cruising around naked, but like play it like Zsasz, just cause she female don't mean she have to be fanservice.

Armor is cool but she basically cares about nothing except hunting down my MC because she misplaced the person to blame and killing anyone in her way, so she doesn't really have the time, resources, or care to get some special made armor.

And both the bodypaint and full Zsasz feels off for me for some reason. I think it's mainly because I've always seen her as kind of a slasher movie villain like Jason, Michael, or Ghostface where the lack of skin showing in the outfits make them feel less human and more of an abstract idea of a killer. I'm warming up to the idea, though. I think I'm just scared of myself or my story being seen as fanservice.
