I bought a japense manga comic of streetfighter3, in the comic it features ken taken over by the dark hadou ryu is also in his dark hadou form, they both fight but ken is stronger he punches ryu and ryus arm is ripped from its socket. Akuma is watching the whole fight unfortunately i dont speak japenese so i couldnt read the words.
But that anwsers the question about who is stronger out of ken and ryu.
get used to gaps in your responses, because people do different things all over the world, in fact its rare you'll have a one on one back to back conversation.
Go to multiple forums to maximize your time, there's comic versus, game discussion, off topic(super fun, you get to flirt and get pictures on your posts), general discussion, music discussion and more, you'll get bored waiting a long time for someone to respond, because they are usually moving around as we..
