@matthewparker: 1 There are cool Asian superheros.
2 They are American comics most of which were created in the 50s, and 60s, and are no more America centric than any other country is. Come to Japan all the super heroes are Asian. And they have a hell of a lot more comics than the US does.
3 One character in the books Psylock who was a twin sister of Captain Britain (can't get any whiter) was changed in a convoluted story just to make her Asian.
I'm American Indian we don't have super heroes there are like 3 total and all of them can talk to animals and stupid shit like that playing on stereotypes. Still that doesn't mean I wanna change Spider-man. There is nothing from stopping myself or others from writing our own comics and making the characters whatever we want. Most Americans are white and so is the market. There is more racial diversity in comics in the US than anywhere in the world.
