Yes, and those examples actually are the case. In Kang's case, we only got evidence for one of his Variants in the series being white.

In the source material he's white & the Marvel cartoons stick with the races of characters of the source material.

& don't say Mighty Avengers Nick Fury because 1610 Nick Fury before the MCU Nick Fury was black

Mighty double standard there if EMH, the Anime, and many others can combine Ultimates and 616, but the MCU's base beginning concept doing that is apparently wrong.

What race has the MCU done that's from 1610? Because most are the same race as they where in 616.

Like I said before several times, there's such thing as race swapping in a good way but the MCU isn't doing it. They change Namor to me the racial diversity quota & not to be diverse. If they want diversity, Marvel Studios would make something for Robbie Reyes, Spirit Rider, etc. Not race swap a white character.

Nick Fury. You literally just said it.

And they did do stuff for Robbie. It's more the TV division screwed in general beyond the white guy Daredevil, but that's a whole other matter. It doesn't mean their other moves of inclusion like Namor are bad moves. Especially considering Namor's traditional backstory was way too similar to Aquaman.

Nick Fury was a race change in the comics.

& Namor's race change literally screws the the world building of Marvel & his power. & his backstory was almost nothing like Aquaman's. Aquaman was raised as a human & raised to care about the surface. Namor was raised in Atlantis & learned to hate the surface. As the king of Atlantis, the Poseidon worshipping society partly founded on magic, he wields a powerful weapon, Poseidon's trident which is also magical. They don't use Vibranium, that's Wakanda's thing & that's what makes them Wakanda. The change of Namor destroyed the thing that made Wakanda unique, being a Vibranium founded society.

& Mayan Namor's city outclassed them with their own tech by making a Sun when Wakanda should be making tech that can kill the Phoenix Force.

And how exactly does that matter? Do the comics have to change a character not affected by race first before an adaptation does it and still adds to the character greatly?

Here's a couple of things about Namor.

1. His initial backstory being similar to Aquaman was about his origin, not his motive. In said origin, his parents were an Atlantean princess and a human. Similar to Aquaman before the deviation of him hating humanity. Which they still kept.

2. As for Atlantis itself, they changed it precisely because we always do see Atlantis in media. Including planned just that point in time was going too close to Avatar and pretty close to Aquaman. This allowed different aquatic based cultural stories to be told in order to be far more unique, but still true to the character's story and motive. And especially more true to his already less western inspired look.

3. Vibranium was never Wakanda exclusive. Most of it is in Wakanda and that still is the case here, but Vibranium is not an exclusive resource to them. Not entirely, even in the comics. And here, there is even less of it accessible by the Talokan. For they simply used it for their artificial sun mainly. As well as for a combination with the algae in order to develop different chemical reactions within their own bodies. Such as the iconic blue skin.

You do know they didn't literally make the sun right? I really hope you don't believe they did cause...

Well the movie would be gone before it started if that legit was true.

1. If people get caught up on him being half surface half water dweller, they're idiots.

2. All that sounds like is that the adaptors lack the creativity to make it distinct from the Aquaman & Avatar even though it's easy. & it's not like media cares if something is overdone. They still make movies about people moving into demon possessed houses, they still make movies about demons in general, they still make movies/shows about magic & the occult so something being done over & over again doesn't mean anything.

3. Yes Vibranium is used by others in the comics but no one else uses it like Wakanda to any degree, especially for making energy sources like a sun. But Talokan was founded on Vibranium in the sense that without it they wouldn't be there, like Wakanda, which is what made it unique. They didn't just used Vibranium to make a shield, sword, armor, etc. like other surface countries. They literally used it to rewrite themselves. They are basically the same in the sense that Vibranium made them what they are today, which destroys Wakanda's uniqueness as the country whose founded on Vibranium.
