Madara would not have been defeated by naruto and sasuke. Sorry but kishimoto stated he couldn't find a way to kill off madara because he was so strong. So he had black zetsu do it. Madara is too strong.
Sakura is useless in high tier fights, contrary to popular opinion.
Itachi is not more powerful than Madara. Even EMS madara is stronger
As far as we know, totsuka blade must pierce the enemy in order to seal it. So no, itachi isn't going to just wack madara with the sword and win the fight.
Itachi can not speed blitz with the totsuka blade. I mean it might be possible but it's not going to catch everyone off guard. That's just simple facts.
Sasuke is not a more well written character than Naruto. That's opinion and propaganda promoted by Sasukebase.
Naruto does in indeed have a blood lusted, "no holding back" mode. All characters do. And that makes naruto the strongest
DMS Kakashi is the second strongest kage after Naruto
Hagoromo is still stronger than naruto and sasuke until we know how powerful he was in his prime. Even after thousands of years of being dead he was able to bring people back from the undead, summon back naruto and friends from ANOTHER DIMENSION, and give away a ton of senjutsu. When he was alive he created the moon, sealed the juubi with his brother. Among other things.
Sasuke's ameno was nerfed. Unnerfed ameno allows him to teleport other things. But now it seems as if he can only teleport himself. Proof it was nerfed? Well he would have soloed naruto, kaguya, and momoshiki and kinshiki EASILY if it was unnerfed. Imagine him teleport naruto into his chidori, instant win.
Naruto still has Rikudou Sage Mode.
Juubi Jinchuuriki, tree absorbed, Madara is stronger than almost anyone in the NarutoVerse
