Sorry about not having noticed this earlier. I've never heard of the Manga so I looked into it briefly and I guess it would work. Again not sure what aspect of the manga you want to capture but I feel these powers for these two are pretty solid across multiple settings.



Since your are still in the process of coming up with a potential story, Perhaps I can throw some stuff your way for something I've been wanting to do but haven't due to the writing part, so that maybe you can pull some ideas from it.



First it would be neat to incorporate the abilities of real mammals and extend it into magic/powers interacting with the physical world. Burrowing mammals moving the earth, arctic controlling ice, ambush preds muffling sound, tree mammals wood weaving, etc... Stuff to really incorporate animals into the world as Zootopia did. Obviously you could have fun with certain mammals having powers their species wouldn't normally have or having these extra powers on top of their normal ones, obviously making this a rare thing and those that do posses it important. Perhaps this could also open up a contrast between N&J where both are gifted but Judy welcomes this power and responsibility while Nick may initially not want it.



Another cool thing to see personally is seeing a bit more of a primitive or classical age world, something very unexplored in the fandom. It's a great way to integrate powers into all aspects of life and culture. Maybe you could still keep a centralized organization that that could be the equivalent of the hero high school to keep peace among the species or something. Rabbit Clans Fox gave me an itch that isn't being scratched.



This is just what I personally want to do but I don't really enjoy the aspect of physically putting words on paper in a captivating way. Would be fun to make some pseudo comic one day, but feel free if anything sounds interesting and works with what you want to do. Also while I appreciate the the credit you want to give, you certainly son't have to for general inspiration.



Anyway look forward to what you come up with if you follow through!
