Actually, he beat Zabuza one on one. The first time he had Naruto and Sasuke's help thats true, but the 2nd time I believe that he took Zabuza down pretty much by himself. He may not have killed him, but he took out his arms. Shinobi with no arms-no jutsu. Useless. Orochimaru was the exception, only because his body had been experimented on.They might be S CLASS CRIMINALS but plain and simple and its easily seen kikashi is no where near kage level.....he couldnt beat zabuza one on one ....he cant beat no akatski one on one... tell me one of them he could be by hisself..? i told he is bad ass but hes not kage level....
