I haven't tried him yet, hopefully he's better than some of Jjong's creations.
EDIT: Oy.....I hadn't realized it but he's based off the second form of Mr. karate from SvC Chaos for the xbox. Comparing him to that he isn't really good....His invisible air blast or whatever knocks them down and doesn't even come out fast. His Shoryuken (im referring it to that cause I cannot remember snk move names) is very odd, doesn't even jump that far off the ground. The only thing I really like about him is his counter move. Hell his grab just puts the enemy on the floor, no animations at all. BUT with all this in mind he is only a beta. So maybe when he is completed he will be better.
