Well, while I can't name a particular 'girl struggles with captors fanfiction', if you look for it in some well - known fanfiction communities, you might be able to find it. Some communities have tags and categories that can help you narrow down your search. Also, you can ask other fans who are into the same genre or fandom for suggestions.

The Thanagarians could be the captors. They are an alien race with advanced technology. If they perceive Wonder Woman as a threat to their interests in Earth or the universe, they might capture her.

They might want to use her as a key to unlock some sort of dark power that has been sealed away for centuries. This would create a really interesting and spooky fanfiction scenario.
Maybe a group of rogue Pokémon hunters. These are people who don't follow the normal rules of Pokémon catching. They might be after Darkri because it's a rare and powerful Legendary Pokémon.
