naruto did beat the bijuu or was at the very least portrayed as being stronger than them since he:Understand, Naruto never beat the Biju. NarutoBase has this stupid assumption that one hit is equal to a loss. All Naruto was able to do was pull out the Chakra Rods. You add a 50% Kurama and 8 other Tailed Beast. One of them with the power to seal.
1) matched their strongest attack w/o using his strongest attack
2) had them in a choke-slam immediately after
Considering what a mere SM FRS did to Yang kurama, BM Naruto could have just had his KCM clones fire FRS at the bijuus instead of pulling out their chakra rods and they'd have been in the same state. He just didn't need to do that. He was also instructed by son goku to hold back his power in order to not kill them, and that was BM Naruto's first time even using the mode.
Then there's the fact that current naruto could mop the floor with an army of BM Narutos.
So no, add yang kurama who got canonically downed by a SM FRS, and add a weaker bijuu than himself, and nothing changes. Naruto stomps them with zero effort.
then why are you making this thread that assumes that sasuke took such little chakra from the beasts that they'd be able to fight?We don't even know how much Chakra Sasuke took from those Tailed Beast.
