kidomaru & kimmimaro(without illness)
vs hidan & kakuzu
let me preface by saying that the spider-guy would fight hidan and the bone-guy would fight kakuzu.the fight would take place where kimmi fought gaara and rock lee(a field surrounded by dense forest).
i think this sound-nin team would win given their cheapness and overwhelming definsive abilities.
kidomaru would handle hidan with ease if he got him into the aforementioned forest with his traps not to mention hidan wouldnt be able to draw any blood because of his iron skin jutsu
kimmi and kakuzu would have a pretty serious battle going on.but we can get into this as the thread progresses (if it does progress

)

im aware that this thread might be frowned upon but i think it could be interesting so bare with me if you please.let the random sound duo versus the weakest akatsuki duo commence!!!
