Well no wonder you didn't get since you'll have KO every character in the game with every character, not just with one. Meybe you are talking about character spesific achievement, so for that you'll have to KO every opponent in one playtrhough in arcade mode without loosing a single round.
This what I did with ryo but still nothing... Any other way...
