GreatestSin the only reason he survived the naruto in his 4 tailed mode is because of all his nasty experiments

jiraiya nearly died from fighting naruto in his 4 tailed mode and jiraiya was actually stronger than orochimaru both tsunade and orochimaru were rated at 35 in the databooks with jiraiya at a 35.5

in the end he only survived his battle with 4 tailed naruto because of his Orochimaru-Ryū no Kawarimi no Jutsu

where he sheds his body and has a brand new body with injuries removed had he not had that jutsu he would have been dead the moment he got sliced in half
