That's why Breath of the Wild Link's default look is a green tunic and a pointed green cap.
Huh...a iconic character not having their iconic clothing but still looking the same as they always do underneath said clothing, where have I seen that before, oh yeah, Metroid Fusion.
Also...you can actually get a official green tunic for botw, it even has a story presence making it more canon then the rest of the clothing.
Who is to say Samus has reached her "final" design? Maybe she gets exposed to some space radiation or something and it changes her skin color.
Typically, I'd consider a character reaching it's "final design" when said design is being used to make toys or amiibos or represented in various Smash bros games. Let's say hypothetically the did do this, should they burn every non-reboot Samus figurine and amiibo, and completely eradicate the existence of a pre-reboot Metroidverse from Smash Bros and from their virtual console? Or should they just have two very different looking characters with the same name and life both bidding for the same marketing and relevancy?
As evidenced, Samus has undergone significant physical changes from hair color to body shape, yet I don't recall similar outrage in response to those adjustments on the same scale we've witnessed in this thread. Samus Aran is an automaton. There's no culture, ethnicity, or behavior profile typified to one class or another. But oh no, we can't make her Black because that's not what she is. More like that's not what she's about. Then you have closet racists suggesting an all new Black character instead, as if they don't know fans will be clamoring for Samus to return like Jason Bourne after suffering Aaron Cross. They'd miss the old Samus with whom they gelled on such a personal level over the course of these 30 years.
Samus has evolved from a brunnete white woman to a blonde white woman. That's what happens with characters over time, they're design becomes homogenized. There has never been a change as significant as a change in race, and if you genuinely believe there has then you're fooling yourself.
