But which do you think has the higher possibility according to the evidence given by the manga, sasori > third kazekage or third kazekage > sasori? Or would you say they are equal?
Sakura is able to dodge sasori puppets (once she has knowledge) even without chiho's help.
Minato would have no problem doing that.
Hiruzen is hyped to be > hashirama so he beats hashi's opponents.
Tsunade has a good chance of beating sasori as well since none of his jutsus are overpowered instant kills (which means creation rebirth makes them useless), tsunade is a medical specialist and therefore there is a good chance she has immunity or a counter to the poison, and she can dodge way better than sakura.
I really don't know anything about tobirama. he has an unknown space/time tech, and edo tensei on top of the weak stuff we saw him pull on old hiruzen. If his edo is anything like oro's then he probably wins as well.
The manga hasn't provided enough evidence for me to choose. It's really that simple.
No, just no. Sakura would have died without Chiyo. End of story. Who cares what Iruka sensei's weak self said about Hiruzen? Anybody is the God of shinobi compared to him. Not everything stated by a character is meant to be taken in the literal sense, or is necessarily true. Itachi said Jiraiya can solo both him and Kisame. Was that true? And almost everyone in the sound village considered Orochimaru to be their God, was that true? Iruka wasn't even around to see Hiruzen in his prime. The only real God of shinobi is the SO6P. People need to stop relying on that stupid line, and even if Hiruzen was the shit in his prime we don't know enough about him to automatically consider him the winner.
Tsunade can probably make an antidote, but it wouldn't matter because she's not going to make it in the heat of battle. Not to mention Sasori doesn't have to hit her directly, he can emit poison clouds from the Third Kazekage puppet. Tsunades only chance is to activate her seal and blitz Sasori. That's easier said than done, I don't think she's getting trough 100 puppets alone.
But to stay on topic, the Third Kazekage was said to be the strongest of the Kazekages whether Sasori existed or not. So if you take that into consideration, and compare it to what we've seen from Gaara it's safe to say that he was one badass mofo. His iron sand, the fourths golden sand, and Gaaras sand put together would make a sand wave so ****ing big and heavy that the only person I see surviving is Hashirama.
