Whoa, way to completely ignore every piece of literature, film, and electronic entertainment that has ever come out of every country ever.
If we're just talking about video games, The whole cast of both bioshocks were really interesting characters, especially the second one with that dad who went down to rapture to save his daughter, they did so much character development pre-release that when you saw him in his new form it was a REALLY emotional moment. That's just one example.
Comparing non-Japanese comics to Manga, you get Watchmen, V for Vendetta, Batman, etc, VS well, I have limited exposure to Manga and anime, but from what I've seen the characters are always very two dimensional and their growth is always a growth in power rather than psychological or emotional development.
The characters in a lot of Japanese media seem to be pretty camp in their motivations.
Also film? The film industry being completely dominated by the west for a very long time and almost every great movie character in history has been non-Japanese.
However, I don't want to turn it into a comparison of west vs east, because if we alienate one side we don't get to enjoy the significant contributions. Art is art, from any country.
