wow, her mouth looks really big in that pic.
How can an Egyptian queen be a modern day Latina? Its just as bad as having Hector Hall be white. As for Hawkgirl, she is, has & always will be a sidekick. Might as well have Cassandra Cain. If they want to have a Latina for diversity, why not cast her as the Lorena Marquez Aquagirl?.
Kendra isn't a direct descendant of an Egyptian queen, she's the reincarnated version of one so she can be any race. Also, Hawkgirl has long since transcended the sidekick role for decades now.
