Well let’s go back to the main retcon, the big one. Why is it a thing that exist? Simply put, to remove Mar-vell from Carol’s equation. The magnetron explosion didn’t cause Mar-vell’s power to be transferred to Carol, no, it just activated her latent already present super kree powers, a news she takes wonderfully and very emotionally.
Ooooh, congratulations Carol! You’re a REAL hero now. All the times you saved the day before, all the struggles, all the fighting, those finally matter because now we know you didn’t accidentally get your powers from some dude. The power was in YOU ALL ALONG. Before today you were just incomplete, a fake hero, a pretender I guess. Now you can finally take credit for all that stuff you did with your hands, because your powers come from your mother and not from an accident. You’re a real Hero, unlike assholes like Spider-Man. Ah, that poor bastard got powers by complete chance and he wasn’t born with them, what a poser am I right? He wasn’t a chosen one, he didn’t come from a powerful ancient lineage of superspace warriors, HE SUCKS! (Don’t you people try and bring up that Totem-****, I will scream).
It’s all so cynical and fake. All politics, just politics, “Carol can’t be a great FEMALE hero if her powers are tangentially related to those of a man.” People that believe this **** are probably the same ones that don’t read Batwoman or Supergirl comics because of the name. Carol was heroic without being born as such, she was a self-made woman that struggled to get her career going, and despite all adversities, succeeded. She got her powers by accident like countless other heroes, and made the best of the situation, helping others. As Ms. Marvel, she was eclipsing Mar-vell’s role in importance and wider appeal, all this while still being tied up to him.
And now, ironically, the new Ms. Marvel sells much better than her and has a much grander following, and how did Kamala get her powers? A mad king from a flying city blew up his own home and covered the world in with a toxic mutagenic fart, that’s how. Hardly empowering, but that doesn’t seem to be a problem for her, or her sales.
