Setting Hidden Waterfall Village
When you say at their prime, what do you mean for Obito and Nagato? Are we talking Nagato with 6 Paths but a cripple, Nagato healthy and walking but with no paths, or healthy and walking and has his 6 paths?
Same goes for Obito. Obito at his prime in my book is one sharingan, one rinegan, and 6 paths at his control but I'm not sure others would count that.
