Re: Which flashback you want to see the most?
That's true. Although the rinnegan thing is part of the madara's lost days.theres so many other flashbacks that would have been great to see like a history of Dan, the Sage vs Jubi or the Sage's life overall, a flashback of the Uzamakis, how Madara gave Nagato Rinnegan, a history of Shisui, history of White Fang, history of all the jinchurikis, how the 1st and 2nd Hokage died, a flashback of Kabutos history, etc
