Obito,That Guy Didn't die
1.When a boulder fell on him
2.When The Juubi was extracted
3.Kakashi nearly killed him
4.Bone no jutsu
BUt Nagato has more Chakra....If you talk 'bout strength Obito wins Lol
I can't see any form of Nagato sustaining Bijuu Level Genjutsu coupled with Jinchuriki paths with secondary Gedo Statue chakra rod restraints, all while performing jutsus as well.
Nagato could handle two Rinnegans, Obito said he lost to one's overwhelming chakra, and it was why he survived as much as he did. Nagato takes this one easily.
Off topic, you've been making a hell of a lot of Obito threads recently.
