Which speaking of, takes me to my next point, is there an already-existing female character that could fill that role better than the genderbent male? Female Thor makes me deeply suspicious* of the author's motives because if they wanted a badass female Asgardian Valkyrie, Sif, and Freya and standing right over there available.
They had the perfect human female to hand an Uru hammer too as well and her name is Orroro Munroe. Hell, she's earned the respect of Thor and stood side by side with him as they both hurled storms at Magneto's shields only for Eric to beat the absolute fuck out of both of them. He saw her in action, hell
they bled together. And she was already associated with mysticism and weather deities.And she's a fucking warrior to boot. So it seems to me like it would be a no brainer choice for Thor had he wished to pass an Uru hammer onto a human and not an Asgardian female. Granted I'm glad they didn't, given the shitty politics and infantile personality of the writer who handled FemThor.
Race Swaps can also happen similarly, with a character revealing their race/learning about their ancestry, even long after being created. One good example is Magneto. He was created in 1963, but 'became' a Jewish Holocaust survivor in 1981. This really enhanced the character and made him sympathetic.
That reminds me of the rumor going around about Denzel playing Magneto. And it gaining a shitload of heat from everyone and their mother and I remember thinking, you could make it work. You'd have to give Eric powers closer to his comic counterpart, for whom extreme old age shouldn't really be that much of a limiter given he once rebuilt his body as it was being descorporated. You could basically make Denzel a former slave, maybe as a nod to his Glory role, he's an ex slave who started out hating whites and then ended up with the mindset we saw towards the end where he was like "White, black this is on both of us" maybe he survives a battle because his powers activated and he was able to "fix" himself by creating an EM field that kept the blood from becoming infected. Have the guy start out, maybe as a proto hero. But over time he sees everyone fail, grows disillusioned with humanity and decides to withdraw.
He has his first run in with other mutants, say in the Spanish American War era, maybe he meets Wolverine or Sabertooth and the thought of there being others out there like him causes him to maybe play around with his own energy fields and he ends up restoring his youth and he goes out into the world again but by the end of the second world war he believes mutants are as lost as the rest...until he meets Xavier in the 70's or 80's? A mutant counterculture activist who actually inspires him to get off his ass and he wades back into the fray but this time he decides to be the cynical voice on the dudes shoulder and overtime they have an ideological rift which brings us to current "MCU" era X men.
It's not..perfect, but at least it would keep Eric's "Never again" mindset and explain why he's so zealous without the holocaust motiff. Because he's seen a dozen generations come and go and burn their opportunities. He's nearing two hundred years of age and is too tired to be patient and kind and nice..Results need to happen now, no matter the cost, mutants can't afford to become like their parent species..yadda yadda/
No studio would take a risk like this though
Which is why a lot of gender and race swapping happens and why it's so dumb. It's about pandering and sanctimonious morons pushing their garbage beliefs on an audience they believe is as infantile as they are and needs to be lectured.
