Amber isn't in the comic for all that much, though. She's Mark's first gf and someone who asked him out without knowing who he really was so Mark more or less fell into the relationship with her but then things get complicated when he leans more into being a hero and spends more time around Eve. Making Amber less desirable, as well as race changing her, does little else other than make it far easier for the audience to dismiss her as most won't care for the relationship like happened in the comic, albeit probably still not as much as they could have done.

The race change will make her later domestic abuse plot all the more stereotypical, however.
