Little rant here//
First off all, no hate to the people who have done what i am about to complain about (I myself, have done this in the past), I'm simply just airing out my opinions.
Why do we feel the need to specify if the reader/oc is black? Why do we seem to always announce that there's a black main character? If the character was white, you wouldn't even need to specify the colour of their skin, you'd be able to find out through the context given (or some people might just assume). I know how back in the day there were really only white main characters, with their straight, blond hair and blue orbs. But there is no real need to highlight (almost glorify) that your main character is black.
In my own humble opinion, representation-- especially of minorities and other underrepresented social groups, should be shown not told. Don't just rebrand an already existing character, slap a different identity on them, call it a day and claim you're making movements in representation (*ahem* Disney's new Ariel film). At least if you're gonna rebrand an already existing character, be creative, be original. Make them just as good as a character you would do to there white counterparts, because that's what we deserve, it's the bare minimum.
