Well, Hitomi is a German fighter. I did expect some German accent or something but there´s nothing there. So don´t expect too much with Marie Rose´s accent.
Okay thatt''s something that actually bugs the hell out of me.
Christie - British Accent
Helena - French Accent
Bayman - Russian Accent
Armstrongs - American accent
Hitomi -...american accent even though she lives in Germany?
The asian girls get a pass on accents because there's no way they'd pull an "original Mei Ling" on them.
Mila also gets a pass because it doesn't seem like she's FROM spain (Working in an american diner at 21 or 22). just hispanic heritage (barely...I don't even see it, except for the figure). She could just as easily have a spanish accent, though she's fine without it.
Kokoro, Hitomi, Lei Fang, Jann Lee, etc should have accents. Ninjas get a pass because I imagine they'd train to have local accents.
The hard part is having accents without being hilariously racist.
That last bit said, TOTALLY okay with swedish chef marie rose.
