I don't really know much at all about the people behind the Square Enix games, but this Normura names come up a lot, and he seems to get a lot of hate.

The characters in Final Fantasy XIII looked fine, except for maybe Hope. Fang, Serah, Vanille, and, to a lesser extent, Lightning, were good looking. All of them seem to have weird clothing choices, though.

And I can definitely tell that someone else worked on the characters for XII. They look a lot different from XIII and X.
