Such as The Flash and Supergirl from the CW world of Superheroes? Because I've been trying to find a co-writer who's familiar with that world, inside and out.
Sorry I only know them from the movies and shows. I haven't seen everything plus I am not great at remember the stuff you are looking for. I would just advise you rewatch anything with the characters you are using and maybe take some notes. Don't worry about being perfect. Listen to any readers and try to slowly improve. You can also do a rewrite if you need to in the future. If you want to give yourself some more room you can give a different characters their power or a similar power. If you do that then it would make sense that the character acts differently or that the power doesn't work the same.
I'm sorry, I just I'm frustrated because the way I write is me and a co-writer work together as a team, and we would just throw things at the wall, over and over again until something stuck. Sometimes it'd would be good work and sometimes it a hubbled together mess of ideas. But I do know one thing. I like writing Superhero Smut with a co-writer if he or she doesn't mind it too much.
