>>84662915Since his mother seems to be non-specifically white American he's not full Mexican to start with, so maybe. It's not like he has a Mexican accent or throws in random Spanish words either.
The name "Diaz" kind of gives it away though. Even his first name to some extent.
Then again, he's way darker than Star in the style of the show, and she's obviously white. Or at least she's a member of a light-skinned alien race.
