After Naruto and sasuke met the safe of six paths they were both given rinnegan in one eye
After the battle sasuke's rinnegan faded away
But Naruto still had his and he trained for years

Naruto and kurama trained for many years so now Naruto's face has sharper fangs and more noticeable whisker marks (this is why his face is covered)
Naruto covered his other eye so others can't see it because he can not turn his eye back to normal
Naruto can control his other eye now he has byakugan , sharingan, sage, ninetails
Naruto has long hair (but you can still tell he's a male)
He is very tall now
And his voice sounds like a strong and determined young leader, but has the wisdom of someone who lived for centuries

Naruto returns to hidden in the leaves and nobody can tell its him

What will happen?
Well it's your story now so you decide!
