ItachiWasAHero wrote: Nagato is an Uzumaki just like Naruto, he has MASSIVE chakra reserves just like Naruto and his chakra is extremely powerful like Naruto's, plus he grew up with the Rinnegan and Mastered it, that is the reason that even while he was still technically crippled he still almost killed Naruto and Bee and he did it swiftly. Nagato was a monster and only plot killing took him out, and when he came back as an Edo, it defeated him. I don't see Sasuke as being a threat like Nagato COULD be, but never will be due to plot and story events.

I don't know if the Rinnegan needs this much training. I mean Madara said that he awakened the Rinnegan shortly before he died and when he got back as Edo Madara he could instantly use all Rinnegan abilities, which were stronger than Nagato's (well I don't think that in his near death conditon he had the time or the strength to master it at that time)

So when Sasuke would get the Rinnegan, I think that he also could master it very quick and like Madara he would be the true owner of the Rinnegan eyes.

It's like with all abilities the characters get. They almost don't need time to train or master it, like Sasuke when he got his EMS he could instantly create a new Susanoo or when he got the Hagoromo power up he could instantly use perfect Susanoo. As well as Naruto, when he got KCM, Bijuu Mode or Six Paths Technique he instantly had access to new techniques without really training it
