Jiraiya and Sasori are two of my favorite characters from Naruto. I have to say though that Jiraiya takes this and not because of his title either. Blaze, your argument that Jiraiya can’t use his summons because of the area that they are fighting on is not clear to me. What do mean by this? Is it because the barrier created by the Sound Four is activated for this fight too, and if the summons touch it, they turn into giant frog legs? Or is it because the building won’t hold the summons’ combined weights? I need more confirmation of what you mean by this statement.
Hiruko:
Anyway you have started Jiraiya in sage mode which means Ma and Pa are with him. He doesn’t need to use frog kumite to crush any of the puppets. The last time I checked the puppets are made of wood, so fire will affect them. The fastest part about Hiruko is his tail. He himself wasn’t shown in the manga to be fast, so Jiraiya’s Swamp of the Underworld is a nice way to completely bury Hiruko with Sasori inside. If Sasori can escape the Swamp of the Underworld or Jiraiya only captures Sasori, then Jiraiya can finish Hiruko off with either a normal fireball jutsu or a combo of fire and wind with Ma and Pa. Sasori has poison, but Uzumaki16 has already brought up that Jiraiya can use fire to counter all the poison covered weapons, sand and poisonous gas.
The fire can be used to sterilize the poison from the senbon and Hiruko’s tail. Then Jiraiya can use his Needo Jizo technique to block the senbon or the tail.
Third Kazekage:
When Sasori uses the Iron Sand technique Jiraiya can first nullify the poison on the sand with fire. Then because of the boost in Sage Mode dodge the sand. While the sand, assuming Sasori used all of the sand in one attack, is away from the Third Kazekage puppet, Jiraiya can attack it with a combined fire/ oil bullet attack or fire/ wind combo attack. The crazy arm attack can also be countered by using fire attacks assuming those arms are wooden. The poison inside the arms probably would be released but can be blown away by a wind jutsu or maybe even burned, not really sure about this method though. I doubt Sasori would risk sending the Third in for close combat.
100 Puppets:
This is tricky because like everyone has stated it’s a lot of attacks to keep up with, but Jiraiya is in Sage Mode, so he can sense the chakra threads attached to every puppet, so he can at least sense where all the puppets are at one time. Going strictly from memory, it didn’t look like any of these puppets had long range weapons, so they are going to have come in for close combat. I guess they could throw the swords and everything, but Jiraiya’s Needo Jizo could deflect them. If Sasori tried to swarm Jiraiya and overwhelm him with all of the puppets from different directions, Jiraiya would have Ma and Pa to watch his back and use their fire and wind jutsus while Jiraiya uses his own fire jutsu, or he could use a substitution jutsu or clone jutsu then follow it up with a giant fireball jutsu to finish them off, or he could use shadow clones to help use fireball jutsu and watch his back. Sasori is too vulnerable when using the 100 puppets because he has to focus on them, which can be a huge opening for Jiraiya. Sasori may send a swarm of a few puppets and wait to see how Jiraiya reacts though.
Sasori:
Sasori really isn’t that scary of a puppet. It can use fire, water and has a hose type thing full of poison and a couple of scythe fans. Jiraiya and Ma and Pa can overpower the fire and water attack with a combo jutsu. Neutralize the poison and destroy the tail with fire jutsus. Sasori would not face Jiraiya in close combat.
Really this is a tough match up for Sasori because Jiraiya is a pro with fire jutsus putting all of his puppets at a disadvantage. Jiraiya has too much variety for Sasori. Sasori’s poison is lethal, but when it is three highly intelligent and powerful opponents against one deadly and genius puppet master, the three are going to take it this time . . . well at least I think so. Anyway, goodnight.
