he never once beat Orochimaru 1v1. When Orochimaru left Konoha to go to Akatsuki Jiraiya got wrecked. He definitely had Senjutsu then, and by that time Orochimaru had already learned at the Ryuchi cave. Jiraiya's Senjutsu can't help him against Orochimaru himself. They at the least tie each other. Tsunade beat Oro, who beat Jiraiya, who pretty much insinuated he could and can kill Tsunade if she betrayed Konoha in the Tsunade retrieval arc. Basically its like one kills the other in a circle. @Yalo, Oro at the end would kill Jiraiya and Tsunade, he has gained wood release and more knowledge and mastery of edo tensei and senjutsu.
