Yes Wonder Woman is Latina… Linda Carter…her mother, Juana Córdova,is Mexican, Linda Carter has stated that her mother is of full Mexican descent from Chihuahua, Mexico. Lynda speaks fluent Spanish. Viva la Mujer de Maravilla!
I like how they manage to make her look just like Lynda Carter. It looks like she's doing the iconic spin, it was actually exclusive to the TV-show, but I'm sure it appears here as well, this being based on the TV-show.
