in this context fairies are the type that are small with mostly insect-like wings. they can fly but it wouldn't be something they tend to do for a long time (just like how we don't tend to run marathons all the time). there is magic in hypothetical fairy world but of course it is more interesting to think of concrete scenarios beyond just Magic Does It

here are some notes i had under the cut... i will mostly rambling my thoughts out loud. i wanted to post this in case people had more ideas! i do not have a disability myself (beyond having poor eyesight that can be corrected by glasses) so i would really appreciate any input

Summary:

unfortunately my knowledge of cass is very fanon-based, so i dont actually know how she met batman originally. but im thinking for this crossover she was on track to meet him but for whatever reason had to flee to new york.

(im thinking 2003 vibes for this even though there is an official batman tmnt, because i love the 2003 boys. but not exactly 2003 because some of the stuff that happens there would not jibe with the existence of the justice league)

anyway cass would definitely pick up on these dudes ninja-ing their way around new york. im imagining that she follows them when she sees them out and about (leo keeps feeling like theyre being watched but cant find her) and finds them fascinating and fun. she gets into a fight w some purple dragons that provoke her and hence gets the vague attention of the shredder as a potential recruit. but she ends up following the turtles for real and meets splinter who adopts her fairly quickly.

i get why at the time the dinos were animated without feathers and etc, since they could only depict what people knew and what was vastly accepted for how dinosaurs looked and acted.
