Also, I just found out she's supposed to be Japanese? Doesn't look like it to me. Then again, SF's never been very good with race portrayal :/
Around SSF2, I noticed they were going a lot more anime (well, they've always had anime influences notably Fist of the North Star, but the art shifts started) if you look at Cammy's eyes in the select screen port, she has a slightly different style compared to the previous version's of Chun Li.
In alpha things got more full blown, but in my head canon, I explain certain things away;
-Karin, totally can see her bleaching her hair and adopting the ringlet styles, cause, hey she's the daughter of a Zaibatsu head, she probably saw a hair style when they were jetsetting around and said "WANT THAT!"
-Mika, I initially thought she was russan when I saw her, but I figured later, that with her flamboyant Joshi stylings, she could have bleached her hair and be wearing contacts like Ken does (he already bleaches his hair and wears contacts - his eyes are confirmed brown, dunno why they're blue in SF), though she could be mixed in the way that Miller is in Metal Gear (even though he's part Japanese he still has full blond hair) or heck, even adopted. I doubt the last one though, but at least they didn't give her crazy aesthetics in the ways of green haired anime girl. I think Rose gets a pass due to her being special/psycho power enhanced.
Damn it Q stop playing the Sheep in New Zealand and move your shuffling feet over here. Also bring the terrified children with you. Pls and Thank You

Uh, actually Q, people want you to do that.
