Transformation Is a Spectrum
You can see at least 2 types of transformation:
On one hand you got: “The curse twist my body into an unholy mockery of life and reduces me into the base instincts of a beast”
And on the other we got: “Standby, Henshin!”
The first is the classical werewolf curse in any flavour you prefer. It is transformation as a violation. Your body is taken over and corrupted for nefarious reasons. Your own self is consumed and you agency is removed. Most of the horror comes exactly from that. Even if a lot of these stories focus on everything but the transformed.

Do your remember the 00s? Probably not, objectively it was over 20 years ago and no matter how i would like to spin it to feel younger that is a sizeable chunk of any person life.
But if you are as old as me to remember it and watched anime in any way shape or form then you probably remember that cat girls where incredible popular in that era.

So you probably would be surprised to now i was really into Tokusatsu when i was but a wee lad. Like very much so. Formatively so. Of course back then i did not know it was called Tokusatsu i only knew the name was Power Rangers and love it.
