Ok let me put my 2 cents in....both of these characters are underestimated on NB, and I like them both (Shino more)....but I have to give this one to Shino.
Why?: Shino is at the advantage not in numbers but in techs...he can stop puppets from moving (including Sasori), he can block weaponry with his bugs, and above all his bugs eat chakra the key component of puppet jutsu (strings heart...etc) without theses Sasori would fall
But it won't be easy mid-high difficulty
Now to respond to these silly post below
In theory it'd be possible for Shino to continuously eat away Sasori's strings.
But in actuality, there is no way a Chuunin would be able to defeat an Akatsuki in a 1vs1 fight. If this is them facing each other in a fight to the death Sasori would win.
Kankurou managed to poison Shino.
Well guess what? Sasori utterly defeated Kankuro at his own game.
Sasori would destroy Shino. There is really no question about it.
Sasori wins this with ease.
Well explain Shikamar...... see above post
Sasori has over 100 puppets that can use all the abilities of their lives when they were alive including kkg. Shino has bugs but not enough to destroy all those puppets, and they arent crazy fast FTG bugs either they arent go to fly fastly at his main body. And even if they did Sasori isnt going to just stand there and wait for them, and even if they did magically get to his main body fast enough hed just jump to another body.
I'm praying that you dont really think shino would win this. I love him but come on....Sasori destroyed a whole village. Shino is smart but so is Sasori, Shino alone is not going to do this. Aside frm the bug and body thing, Shino is not that fast or that skilled in taijutsu theres no way he'd be able to dodge the millions of needles coming at him that just about every puppet can do. Not to mention the poison gas. And don't say that Shino's bugs can nulify the poison, we've seen shinos dad do that but not shino so you can just assume he has the ability.
Why would he not win? Shino's bugs were fast enough to encase tobi the only reason he got away was thanx to t/s tech....and if we are giving all we have seen of each of them in one of the movies Shino had his bugs eat metal ships I mear seconds so that long list of puppets means nothing...
but even without that Sasori has to have time to summon those and if the bugs jam the chakra thread thing in his chest then the 100 puppets are of no use....
This is a versus thread and its asking who would win. Tell me this then. How are shinos bugs going to get through Sasoris fire element? And Shino doesnt have enough bugs to get through all his puppets.
The same way they got thru the crystal, and the slime in the 3 tail arc, the wax from the bee clan, and if I'm not mistaken konon used fire against the aburame....or simply move the bugs like Sakura and chiyo did
The bugs of the aburame are said to constantly evolve to become stronger so the next gen can survive the techs the previous gen breed into them (ie crystal, fire...etc )
And the bugs only live a week or so. Meaning that they are constantly reproducing....
So in conclusion....Shino for president....lol
