I think Miles Morales (Spider-Man) is a good example of taking a character people like, and making a whole new one, that has his own things that make him different, yet similar to the original. I wish it was done more like that more of the time.

This is how I've always felt. You can make Captain America black. You should not make Steve Rogers black.
