One day, while kicking the lives out of thieves and murderers, Jackie Chan accidentally runs into a man with a white sac and raggidy clothes.
Jackie: Sorry!
Mystery man: Tch, (insert something offensive here)
Jackie: Hey! I said I was sorry!
Argument insues. Some random sorcerrer casts a spell on the mystery man.
Mystery man: Uh.. Hadouken? *Poof* Dag, that darn sorcerrer.
So Jackie Chan and Ryu fight, one on one, fist-to-fist, no super powers, no fireballs. Just pure hand-to-hand combat. WHO WINS?!
For the sake of fairness, we're talking about Jackie Chan in his prime. Not oldJackie chan.
EDIT: Forgot to add my opinion. Jackie Chan would win. Ryu has power and that spinning back-kick, but Jackie has speed and he's pretty strong himself. So Jackie.
