Considering that Marvel character Kitty Pryde’s actually no stranger to being trained by Wolverine (even donning claws at some point), made feline at various points and trained as a ninja it’s almost surprising why almost no writer bothered sticking to either one, both or all of them. But that would necessitate allowing Kitty Pryde to actually mature or develop in ways nobody expected her to.
Though that would mean she’d practically render X23 and even Feral redundant. Or at least become either one or both of them. Actually there wouldn’t be a need for X23 should Kitty Pryde actually be a cat version of Wolverine. (Also it makes a lot more sense for felids to have retractile claws.) But that’s something that even if writers are tempted to, they’re not willing to stick to it either.
At times sticking to the logical conclusion would necessitate doing things the hard way. Something that writers do feel tempted to turn Kitty into a feline Wolverine but one that involves having her move past what others call the idealised girlfriend thing and experience her developing in ways they wouldn’t foresee her to.
She wouldn’t necessarily be Marvel’s Catwoman but there wouldn’t be any X23 and perhaps Psylocke in her expected form if they play up the feline ninja thing for real.
