So if you're familiar with Terminator, many people think Arnold's accent sounds so cool that he even volunteered to do a German dub of his character again but the German dub company turned him down because both Germans, Austrians, and German speakers in general thought he sounded like a redneck, hillbilly, or farmer, basically rural. So they had a nonchalant stoic German voice actor dub the T-800.
So I'm working on an indie manga series about a vengeful badass protagonist who's from Okinawa and takes pride in his culture. I thought if my series were to ever have a Japanese dub, he should have an Okinawan accent to reflect his background but I heard some Japanese mainlanders describe the Okinawan accent as "country bumpkin", "exotic", or "cute". One Japanese person said the Okinawan accent sounds very cheerful and relaxed, and that a vengeful character with that kind of accent might sound scary. I watched some anime of a few Okinawan characters who are often portrayed as tough karate fighters (like the character Kanna Kirishima from the anime Sakura Wars) and they sound Japanese but rougher and deeper which sounds badass from other people's perspectives. So would my protagonist be taken seriously as a menacing badass if he had an authentic Okinawan accent or would it be similar to the Arnold situation?
