When Mr. Freeze made his debut in the 1950's, he was little more then a generic mad scientist with a cold theme. This remained for 40 years until Batman The Animated Series rewrote him as a tragic villain. Heart of Ice was praised so much that Mr. Freeze was changed overnight. Now, nearly every continuity retains this tragic side of Victor Fries.
Netlfix's She-Ra has managed to garner the same praise as Batman The Animated Series, and has even out shined it's 80's predecessor. Before that, Catra (at least to me, maybe not to others) was not really anything special. I've seen female cat themed villains before, with their seductive charms, their meows and hisses and bad puns, and the 80's Catra was like this.
But like Mr. Freeze, Catra has practically become a different person overnight. Now, most people associate her with trauma, mental illness, tragedy, and redemption. And I'm wondering if history will repeat itself and future incarnations of Catra will retain the tragic villain of Netlfix.
