well explain to me how he'll beat it, dont tell me he has this and that. give me a step by step explanation of their battle. Here is mine:
naruto charges at six tailed naruto and hits him with a clever combo but his skin is not penetrated and 6tailed naruto splits his body and attacks current naruto with his claw that could easily split orochimaru into two.
Your argument fails right off the bat. Naruto knows about the strength of the fox, why would he go and punch it in the beginning. He will do the same thing he did against the ninetails: high-powered oodama rasengan, which the fox with only six tails will not be able to repell. Either that, or he uses rasenshuriken.
sage mode naruto's body is a hella more durable than orochimaru's. Orochi got regen to make up for it, sage naruto has never been injured while in sage mode.
naruto retreats. six tailed naruto attacks with chakra arms from underground(like he did against orochimaru) which current naruto evades and goes for another attack but is repelled when six tailed naruto uses his arm to create a shockwave(like 4 taild did against oro and incinerated his multitude of snakes) he begins preparing the tbb.
comparing sage naruto's durability and strength to orochi's snakes is laughable. Also its not only naruto who is attacking six tails, but his clones as well, each capable of performing a super oodama rasengan powered by sage mode, and having the physical strength to throw the actual ninetails really far.
naruto is kept busy with the chakra arms as he prepares it. naruto tries to stop him by attacking but he uses his sensor ability to dodge and fires the attack, thus gaining victory
Naruto in fox mode, and the fox, has never ever shown the ability to charge a tailed beast ball and use chakra arms.
here's a scenario:
six tails sees naruto, rushes in attacks him, clone goes poof while a multitude of sage clones hits sixtails with super oodama rasengans from behind followed up with a rasenshuriken. GG six tails.
