Clouds iconic image in pop culture being a brooding emo is a parody of what he actually was in the original game. That stuff happened under Nomuras watch in his games and media.Cloud is not a parody of himself though. Also, your referring to Nojima writing, not Nomura.
And come on you don't have to defend him so hard over everything, forget Cloud, Nojima hasn't written KH sense 2 and look at what's happend to it, especially DDD, story became nonsense and Sora became a naive idiot dumber then he was in the first game, which is the type of flanderization I'm talking about.
Or should I just blame the other writers even though he is a known micro manager who dictates everything which is how the games all have the same tone despite diffirent writers.
