Like I said before, change’s not necessarily always good nor bad especially in storytelling directions where I think it’s affected by multiple factors and the like. I suspect should certain characters need to change, it’s either to better represent concepts as well as to take advantage of something potentially good (Tigra being the poster girl for body positivity if because she’s hairy and got paw-like hands and feet), to update themes for this generation (Caitlin being a werewolf in the post-Leaving Neverland years) or to consider a logical alternative.
It could be Tigra being the poster girl for body positivity and that’s one thing if because it’s needed and that she can get away with being this hairy. It’s another if characters like Kitty Pryde need to be de-Mary Sued. I guess if there’s ever a perfectly sensible way to de-Mary Sue her, it’s one thing to depict her as a completely normal girl on X-Men Evolution. It’s another to consider the logical possibility of her being a murderous assassin if Age of Apocalypse’s any indication.
After all, Kitty’s got no issue beating up and even killing people especially when angered. She should’ve become the character Psylocke ended up as given her ninja training (and that would actually make much more sense really). The only problem is if they were to make her replace Psylocke and X23 (Kitty at some point had retractile claws and very much so in AoA), writers fear making her look bad. Never mind it’s ironically the least Mary Sue she’s ever been. And parsimoniously the more realistic route too.
Realistic in the sense of taking her tendency and trajectory into consideration. No wonder why Psylocke’s ninja makeover got eventually undone, she wasn’t meant to become this character whereas Kitty could easily become it. Wouldn’t matter if she’s a reader surrogate though that would mean giving her an actual goal and taking her where she’d logically become, which is awfully similar to what became of Psylocke and eventually X23.
(Since cats have retractile claws, it makes a lot more sense for Kitty to have Wolverine like claws too.)
Not to mention she’d end up as a more realistic version of Felicia Hardy (who’s often considered to be Marvel’s answer to Catwoman). Again in the sense of being actually feline right down to the retractile claws and tendency to go through narrow spaces, like actual cats. (To be fair, Extinctioners is a furry superhero comic with a character closely resembling her in some regards.)
So you’re dealing with situations where such characters would realistically become those, whether if it’s Tigra being the poster girl for body positivity as she’s unabashedly hairy with pawlike hands and feet or Kitty Pryde becoming a ruthless assassin. It doesn’t really betray what’s been portrayed whether in comics, the original intent or elsewhere to an extent. Though it’s also a matter of willingly doing the alternative.
Especially if it’s something needed to ease problems be it letting Tigra be hairy and have actual paws or making Kitty less of a Mary Sue.
