The Obsidian Surfer
Neither Magneto or Xavier's character's race play a crucial part in their identity. The Holocaust was used as a basis for Erik's ideology. There's plenty of horrible shyt that's happened to people of all shades based on inequality and one group deeming itself superior to another. Replace the Holocaust with apartheid, Asian internment camps, British rule of India (which gives you a Ghandi/Xavier correlation), etc.
The majority of superheroes don't inherently need to be a certain race or gender. Obviously Black Panther needs to be black, Wonder Woman needs to be female,
Amadeus Cho should be Asian, etc. But Superman's an alien, breh. He can be whatever the fukk the writer wants him to be
