All you guys are nuts... Jiraiya takes this, he starts of in Sage Mode with Ma & Pa....
Jiraiya has full knowledge and he can summon two giant toads, plus ma and pa can summon toads, also he got Swamp of the underworld and Senpou Goemon... How will Gai and Lee counter Goemon? Also Jiraiya using Oodoma Rasengan and his sage art senjutsu is so strong it knocked out one pein in a single blow? Jiraiya can also reverse summon away so he can prepare a plan, plus he can trap Lee and Gai in a toad stomach killing them, if they come too close to him, also Ma and Pa's Genjutsu would come it to play if even needed, Gai or Lee won't be able to handle his Genjutsu.
Plus Ma and Pa can use many different jutsu to help out Jiraiya, dust storm thing, water and fire release, plus their taijutsu.
Jiraiya has enourmous amount of jutsu, and he is way smarter than Gai and Lee combined.
Jiraiya takes this with mid difficulty.
Ill answer two things under this line:
Raito: Speed? you say jiraiya was on the same speed as Pein... since when was jiraiya that slow... Seriously he beat up one pein without pein even got to react, plus he easily figured out their weakness and their abilities after about just a few minutes. He killed 3 peins with a single move (genjutsu, could have gotten them all if he knew about their secret, which is plausible) In the end he got injured and still held his ground against pein, where he seriously still fought for real, and he got past 5 peins to strike with his fist at the main pein, though it was blocked since all peins eyes are linked together so he saw everything happening. So here it is: Jiraiya is way faster than Pein, the only reason pein could keep up, was because of his shared link.
EL MAGNIFICO:Low difficulty? your nuts! how in the world do you come to that conclusion. Jiraiya in Sage Mode is on a whole other level than Gai and Lee. I don't want to even talk about that low life answer to this thread.
