@Dream: Well he does have okay feats from the animated adaptations of street fighter (Alpha and that Street fighter movie/series) so it isn't exactly impossible to find something. Given his choice of the character he should at least know that much.
But as you said, Ken's feats pretty are shallow compared to his best friend's so I can be understanding to that somewhat.
@SpeedForceSpider: iirc he iz at least as strung as jonatan but I'm not sure if it's correct
Still, joseph is at least as strong as jonathan and he also has tha better feats e.e
No he is not at all actually. Joesph is an adapted fighter, he uses strategies and such to defeat his opponents. He doesn't rely purely on the raw abilities of his hamon to win like his grandfather. Jonathan post-zeppeli ripple would destroy Joesph in a straight up fight. Joseph only has an inherited portion of Jonathan's powerful ripple. As for the feats you need to specify what you mean:
Power - Jonathan
Skill/Versatility - Joesph
