If Jiraiya was brought back, I think he'd be like Asuma. He'd tell everyone how to beat him and what his weaknesses are so they would seal him away quickly. But if you mean he wasn't able to do this, I think he'd last for a while but someone would be able to seal him sooner or later. We still don't know if Edo's can summon animals (I think they could) so it's best we wait for it I think. And imo, Naruto and Bee could fight Jiraiya with a sealer near them so they could get to him as Naruto and Bee pin him down or something like that. xd
Do You Think That Edo Tensei Jiraiya Would be Unstoppable ?
With the Unlimited Sage Mode Chakra & Edo Body. Plus his Smart Brain & all Experience he will Be Dangerous. Dont you Think ???
the only invincible edo is deidara too bad plot no jutsu beat him, even kishi say so
Then what would you say about edo Naruto
