Additional characters - the way Connor Hawke is drawn differs massively depending on the artist, but the character canonically has Korean, Black American and WASP heritage and grew up in South Korea. Djinn, The Aerie and Osita are of ambiguous heritage,the first two being ambiguously human, but all are visibly not white. Xiomara Rojas is an alien adopted by a Mexican American couple and until recently considering herself to be a mutant Mexican American girl. Pearl Pangan is a Filipina, Amka Aliyak is Inuit, Raz Malhotra is Egyptian, Cindy Moon is Korean American, and America Chavez is Latina. In She-Ra universe, Micah and his sister Castaspella are fantasy Asian, making his daughter Glimmer a mixed race girl. I *think* Frosta fits too, based on culture and character design clues.
