Yo man what is this is crazy sh*t that is going on when people make there top 10. Apparently there is a Nagato that is stronger then the Nagato who was the 6 paths of pain.
Now people need to realize that Nagato at his strongest was with the pains. Whether you like it or not is up to you. But it is a simple manga fact.
There is no "Healthy , and experienced with Rinnegan" Nagato in Naruto-verse. That Nagato didn't exist. So why do people keep making this imaginary Nagato to put into top 10s, instead of just Pain or Nagato... But people like to say "Nagato (healthy)".... wtf.
