I belive in some point sasuke will join narutos side and tobi will not like this and knowing that he can not take on both of them request madara to come but still just a theory so which side do you belive would win?
Sasuke does not have the sword or the shield. just a FYIwell technically it will be kabuto and tobi seeing as madara is an edo, and i would have to say as long as sasuke has got all itachis techs like the tatsuka sword then he could take care of madara and naruto and sasuke should be able to handle tobi so id say naruto and sasuke
