Sasori vs Mei

[MasqueradeNX]

Sasori is a very underrated and he wins this mid diff or even low if he starts with 3rd

 

[Lariatoo]

Sasori mid diff.

 

[Ghost in the Shell]

Sasori wins this, he kills Mei with Iron Sand variants. If you give Mei enough distance to set up her jutsu, she might win.

 

[Praydara]

Sasori low to mid-diff. Her defense isn't too great as far as I'm aware, and defense is vital against Sasori. Just a scratch insta-kills.

 

[super yang]

ironically, Mei gets blitzed by iron sand inside such a small enclosure.

and of course sasori would win a normal fight w/ mid difficulty at most.
as he can fly, has more range & poison, etc.
