During the Great War, Kabuto resurrects a lot of very, very powerful shinobi (Madara or Hashirama the 1st, e.g.). However, he doesn't bring someone as powerful and impactful as Jiraiya.
My girlfriend pointed this out a few days ago and since now, I wasn't able to find a reason. I see that this Edo Tensei no Jutsu brings up some questions (about more Uchiha's or even Orochimaru) on the table, but it seems that everyone forgot Jiraiya in this equation.
Why didn't Kabuto resurrect Jiraiya during the Great War?
