...really? Ever heard of "light skinned black people"?
I'm pretty sure if Lisa was black she'd be a coon like Zack. TN is pretty stereotypical.
I agree with the Brazilian, South American theory.
No, I think it's more a problem of beauty criteria. If Lisa was a dude.. I mean, if they didn't have to sell tons of bikinis for the Japan audience, for her, she would be darker. So that's why she was "whitewashed". To sell more. Anyway, Afro-American ladies come in any shape and skin complexion, so that works too.
Zack is darker because he is a male, he doesn't have to be "hot" and "beautiful" (from the Japanese POV) because he doesn't have to sell or please a large audience like her. He is not a DOA babe.
I see what you're saying. Beauty within the media does suggest "lighter is better", and what you're saying may be the case. When it comes to her actual ethnicity however, her skin color isn't an issue at all. Black and Hispanic women come in all shades and colors. I'm leaning more towards her fighting style and her being a luchador suggesting she's of Hispanic descent.
