Deidara literally blows him away
Gets in the air, rains down fire on the puppet until hes dead
Sasori never gets close to him
Gaara with the sand of his entire village at his disposal while making gigantic kaiju hands that even individually were way larger than the entirety of Sasoris iron sand reserves combined couldnt land a hit on Deidara until he wanted them to, he finessed them for literally their entire fight despite Gaara being a dedicated long range fighter with the ability to fly.
Sasori hasnt even shown to perform long ranged sand constructs, nor has he shown the ability to fly, nor has he shown the ability to do either of these things at a level remotely similar to Gaara while desert amped, which Deidara could finesse regardless.
If Sakura could read and lol at Sasoris sand patterns, they arent touching a dude who can fly
meanwhile, a single blast from Deidara can wipe Sasori off the map. Even his C2 explosions, when multiple are combined at once, are massive and far larger than anything Sasori has ever made when they explode.
His C3 is a threat to an entire village
Deidara rather easily walks away with the W here
He has way better feats than Sasori and has fought and defeated stronger opponents than Sasori
So just Sasori vs Deidara? Sasori low diff. High diff with prep time.
lol worthy no offence
