@RumikoOharaAccent. Listen to the way that his countrymen speak English. You can find just about anything on youtube. I have a character that has a heavy French/Cajun accent and that is how I had to do it. Research. Then again I'm one of those weird people that research a ton of stuff. In a prior conversation Shield mentioned that I was in another Marvel RP. I did so much research on that one I narrowed down where the incident in Avengers in NYC is at and how many blocks it covered; just to put my character's Apt and work out of the line of destruction but close enough to have an impact.
Research, I love you
I am called by friends in the guild the demoness of details, I too love to research all the little things
When I was running a Magnetic type that wasn't interested in using her powers to fight but instead to lift payloads for space research I researched the average price and weight of those payloads so I could say how much money she was making while charging only 10% of the going rate.
Then I researched the Van Allen Belts and other subjects on magnetism till my posts read like a science exercise
