Jiraya can't mould chakra due to tsunade's drog while fighting Oro without hands...............
Jiraya is stronger than Itachi,Itachi never lied abt opnt's strength he said that Gai stomps Kisame ,and if his true intention is not to fight leaf ninja y did he fought Kakashi and crew......and Kisame knw that Itachi defeated Orochimaru and after that he left the akatsuki and still both of them considered Jiraya is Strong.............
Jiraya is holdng back in every fight with Orochimaru ,his true intention is to bring Oro back ,not to hurt him or to kill him,,,,,,
Itachi able to beat Oro easily bcoz Oro think Itachi is a fodder com to him in his first fight and get stomped by Itachi,,,
and he let Itachi cut him with totsuka bcoz he thought it can't hurt him,,and b4 realizing wat actually happend he sealed by Itachi,,,otherwise Itachi can't win Oro that easily..................
