So I've noticed this character(?) appearing in lots of Japanese games/media. Its this male character who possesses some kind of "hidden" evil/demonic power (sometimes in his arm) that usually takes the form of a demon or something when its fully released...I figured its some form of Japanese mythology since it keeps appearing everywhere...anyone have any ideas? (kingdom hearts) (devil may cry) (naruto) (even this weird ass game) Coincidence? I think not...there are definitely more, I just havent found em yet. Even the protagonist of Princess Mononoke has a demon arm.
