Triple Six
Frisky Wolf Lord
I see Ryu SF winning this because Hayabusa is not THAT faster then Ryu, Ryu was able to dodge bullets from less then 10 feet away with ease in his early 20s, Ryu is damn near 50 now and trains with Oro, so basically he's fast as hell. And Hayabusa's teleport is too slow, Ryu would f**k him up by the time he's done with his little ninja gang signs routine.
Hayabusa is weaker then Ryu, Ryu could lift automobile massed objects, Hayabusa has no feats he can compare to that as far as I know.
Ryu has more devastating projectile attacks, 4 actually not including those of his Evil form. Ryu's normal Gou Hadouken was able to tear large chunks off the face of a sky scrappers that's a better feat then Hayabusa's because of course if your gonna throw energy at a jet it's gonna blow, jet fuel is explosive in the first place. However, tearing chunks off of sky scrappers is no walk in the park, especially if there is no Jet fuel inside. Not to mention Ryu was WAY younger then and only used a simple special move and was only half Evil mode at that. Current Ryu, who is training with Oro is several times greater then that.
I lean towards Ryu in the durability department for now. You see Ryu taking hits all the time, can't really think of a time Hayabusa got hit hard other then the time he got slashed by Doku and he only came back because of the D.Sword. If This is a H2H fight he wont have the sword to fall back on.
Ryu from SF wins...if this is a hand to hand fight, is it Snafu The Great?
