He hasn't been given one yet, but it might be Uzumaki since he is a descendant of that clan
Naruto
Naruto fights and defeats the 6 pains that nagato controlls. After naruto has a talk with nagato. Nagato uses his life force and remaining chakra to restore the lives of everyone kill during the battle.
Family related, no. but they have Jiraiya as their master. A non-family relation and shared master is true....but they both are from the same clan. Both Naruto and Nagato are from the uzumaki clan! Their full names are Naruto Uzumaki and Nagato Uzumaki.
Pein, more commonly known as Pain in North America, was indirectly killed by Naruto. Naruto destroyed all six Pain bodies, and sought out the "Pain master" (controller of the bodies), Nagato. Naruto convinced Nagato that Nagato's answer to finding peace was not destruction; Nagato believed that Naruto would find the answer to peace, and returned all the lives that the Pain bodies took from Konoha, at the cost of Nagato's life.
None.
technically yes ,because madara uchiha said that nagato is from the uzumaki clan just like the mother of naruto so it is plausible
They talk about why Nagato wants to destroy everything and then rule the world
Nagato did not give Naruto any powers. The only thing Nagato did before he died was revive everyone in the village that he killed.
No, Naruto doesn't kill Nagato. Nagato gives his life in the process of reviving people he has killed.
no, it is madara uchiha.
Nagato is the seventh Pain, he is the original possesor of the Rinnegan, and he has the ability to manipulate life and death.
There are 6 paths of pain. They are all controlled by Nagato. If you include Nagato as one of them then there are 7.
