Re: Enough, Naruto never has and Never Will beat Nagato.
Enough of this. Naruto has never beaten Nagato - in that his ability and power was never above that of Nagato's.
However Naruto will be able to beat Nagato concretely in the future, if not he has the capacity to do so now. "Concretely" will come with the advent of 'that jutsu', otherwise Naruto is full capable of beating Nagato by utilizing strategies which combine his Sage Mode alongside his Bijuu Mode - not concurrently being used though. Granted 'that jutsu' would have a higher success rate.
Lets not forget Naruto combining Bijuu Mode and Sage Mode gives him the best tools to beat Nagato and the other two Rinnegan users we know of. Think of it, Sage Mode's natural energy attacks and other benefits while rapidly increasing Bijuu Mode's capabilities?! Then there's factoring in Fukasaku and Shima who can now fuse with him.
About CT, wouldn't Naruto could all out attempt to blast CT? Kurama did before, and surely would recommend the same to Naruto. Naruto would have more than enough fire power to do so, furthermore his single Bijuu Dama is stronger, a lot stronger, than Bee's - stronger than Bee's Bijuu Dama, FRS and Yasaka's Magatama put together, you can say.
There's also the Yellow Flash speed, who says that can't arguably bail Naruto out?
Preta Path can be overcome with Sage Mode and ninja tools. Naruto would be encouraged to rely on this stuff without comrades. Lets not forget summoning.
The dogs, same deal. In fact Fukasaku and Shima may be able to shut it down. Further if jutsu like Amaterasu can shut the dog down, it is probable that the Bijuu Dama can too.
Sage Mode Naruto has a chance at beating Nagato, if he fuses with the toads.
Bijuu Mode Naruto also has a chance at beating Nagato if be incorporates Sage Mode in his strategies. His chances dramatically increase when you consider the Bijuu Mode that beat five Bijuu, and even more so with the full Bijuu Form.
