I usually don't like to talk about Jiraiya, I'm still not completely over his death it seems.
But I wanted to bring this up because a lot of people are just underestimating Jiraiya in this form. This Sennin Mode is by far the strongest there is!
For multiple reasons:
1. Jiraiya has close to infinite Sage chakra in this mode, no limits whatsoever.
2. Jiraiya has the two strongest and actual Sage's of Mount. Myobokuzan attached to his shoulders.
3. The combined power of Shima and Fukasaku is unmatched! They are, in every sense of the word, Over Powered!
4. Not only can Jiraiya dish out his own Nature energy enhanced attacks, but Shima and Fukasaku have their own unique and devastating arsenal!
Make no mistake, nothing can take this form of Jiraiya head on and win.
Asura Pain is undetectable because of his composition. His sneak attack was aimed at destroying Jiraiya's arm to cripple his ability to perform Jutsu.
Jiraiya had also believed Pain to be dead. He thought he had killed him himself, Jiraiya's guard was down.
Pain won because of his secret and because he didn't fight with all 6 Paths from the beginning.U_U
