<p>Madara vs Kaguya = Kaguya. You mention sealing would work, and indeed it would, if the only thing that could seal her wasn't Six-Paths Chibaku Tensei, something Madara did not have. So Despite being way smarter, Madara would lose because Kaguya is more broken.
</p><p>Madara vs Hagoromo = I think it would either be a tie or a defeat. Hagoromo could seal Madara like he did the Ten-Tails, which would just end the fight.
</p><p>Madara vs Obito: Victory. Obito would just be rekt'd.
</p><p>Madara vs Hamura = Tie or Victory, don't know enough about Hamura's personal power but the Tenseigan doesn't look anywhere near as broken as the Rinnegan.
</p><p>Madara vs Momoshiki or Tonrei = Don't know. Didn't see Boruto movie, and I don't know how strong the Tenseigan really is.
</p><p>Madara vs Tenten = Defeat. As I always say, Tenten is an actual weapons master, and unlike everything else in this series, normal weapons are 100% lethal when compared to the ability to destroy a mountain.
</p><p>Madara vs Naruto = Tie. See below.
</p><p>Madara vs Sasuke = Tie. See below.
</p><p>Madara vs Sasuke and Naruto = For these two, in true bromance fashion (and in clear violation of the rules of engagement in this thread) their prime is when they are together. Therefore, in a battle between these two it would either be a Tie or Madara get's defeated. Kishimoto writing himself into a corner notwithstanding, I really believe Naruto and Sasuke are godly enough to kill a god if they wanted to. Not to mention they've shown the ability to rip the tailed beasts out of a jinchuriki, thus removing the immortal part of Madara's power.
