I will admit, I detested him the first 3 or 4 hours of the game with his constant, I am the hero blah blah, but after that, he settled down and it seemed to me like his character developed more and I his connection with Hope and Lightning established and I grew to appreciate him more.
Not to mention he is the best Ravager in the game :P
I liked his attitude and design, but in all honesty, contrary to popular belief, he did not really spout a whole lot of the hero stuff - granted it was one of his staples in the game, he really didn't bring it up as much as people make it out to be.
He is among my favorite characters in the franchise and is my 2nd party member at all times, next to Sazh and Fang
If Snow was a good ravager he wouldn't have needed Serah and Noel help against Flans since they are weak against magic --- Bring awareness to Type-0 and Vs 13 http://www.gamefaqs.com/boards/932981-final-fantasy-versus-xiii/63945817
