blackstar is fast, but only for his universe, maybe supersonic at best and frankly thats what naruto was around the start of shipuuden, probably greater. not to mention his prowess in taijutsu over blackstar, nearly unlimited amount of chakra, ranged and melee weapons that would put him into the ground and if im wrong, then hey, he always has the ninetails to back him up even more
Well the tooth was fawking huge, and looked to be made of rock and he did tip it off them. Plus you forgot him hitting the Kishin so hard he shattered another tooth on his impact. I'd definitely give him the strength edge. The durability edge too given the punishment he took in the Kishin fight.
Basically if Black*Star can hit him, Naruto is toast.
Yeah, Sage mode Naruto shits on Black stars dick. Even Pops, the old frog who wasn't able to beat normal Naruto in an arm wrestle, lifted a 10 ton frog statue with one hand. Naruto has the strength advantage by far. Also, though sage mode is very fast(faster than the third Raikage, who was faster than lightning), its best aspect is its reaction speed, which allows it to react to things before they even happen, making Naruto able to easily rape Black star.
