More to the argument, cross posted from my userpage.... 
 Whether they are or arent' Japanese in origin is irrelevant as the article is in ENGLISH!!!!! Thus the closest form of recognition as to how their name should be represented in English would be either the McCune Reischauer romanization or Korean standard romanization of their name, or in game spelling in English. Hangul should then be second. Hanja 3rd. Japanese has no place in this case because 1. In Japanese versions of the game, the name is represented in romanization, and in story modes also in English! Katakana doesn't belong because it's an ENGLISH article and provides no value whatsoever to English readers. Romanization of Katakana has even LESS place, as it is romanizing something that has altered the original sound to begin with. Since we are romanizing from the source (English title), showing the source(Hangul), and showing the meaning (hanja), why is there need to show how Japanese would best estimate how to pronounce the source in their own language? Maybe if the article was in JAPANESE it would make sense. Go write an article in Japanese and use all the frigging katakana you want. I won't stop you then...Bethereds
