I feel bad to call myself a Madara fanIt's only stupid people who have the belief Naruto or Sasuke can beat Madara, when canonically they needed to work together in order to fight him; which still, they were overpowered in the end.
Rinne Sharingan Madara > Double Rinnegan Madara > 1-eyed Rinnegan Madara = Natural Energy Naruto/Bijuu Sasuke > Rikudou Naruto > Rinnegan Sasuke.
This and will always be the correct equation.
