even i have to admit sasori is the better of the 2 here
c1-simple stuff really even hirukos tail could be enough for this
c2-this would be deidaras best chance imo with the missiles but i cant see it pull off and iron sand could destroy the dragon
c3-he could use iron sand as a defense or if hes in human puppet form he could actually fly so c3 would be useless or deidara could use it which could kill sasori but also himself
c4-sasori doesnt breathe worst move
c0-draw then?
anyway if these 2 fought i would hate to admit it but sasori is the stronger and smarter character
Deidara C4 or C0 and Sasori is dead.
he cant breathe, c4 has no effect and c0 would just end in a draw dude
