I think Betsy is most likely going to be white in the MCU. There’s a decent chance she could be racebent into another race, but I don’t see her being East Asian. I’m fine with any of these scenarios. Steel Inquisitor and crimsontt have brought up really great points in favor of her being East Asian/Eurasian, but I think a lot people would be reminded of the body swap/transformation and get offended anyway.
That’s a very interesting idea.
