Which will win?
Kisame can absorbs their chakra i think, Itachi will create a susanoo + jutsu breaker, Konan will be participated with her secret jutsu, Sasori with poisons, Kakuzu medium damage, if Hidan can get Madara/Obito's blood, DONE. Not to mention Nagato with it's paths. Zetsu little bit. OBITO and MADARA are DONE.
I'M NOT their fanboy, don't look at my uname.
