So Naruto basically fights Kaguya alone, stands high against her, puts one hell of a fight which eventually led to her being sealed and he is weaker than Madara ?
Something is not right here..
If Kaguya had a brain she would end him, a long time ago. He just stalled her. Without plot and nerf Kaguya and Madara would pretty much solo. She was sealed by both Naruto and Sasuke so... And yeah he is weaker.... Madara is like the Sage.
Madara 4th databook translation it is implaied that when he had both Rinnegan back he unleashes the true power of the Sage...
The power of the Rikudou (/Six Paths)
Main Body
よいよ機は熟さん。。。！両眼 の ”輪廻眼”を回収し、六道の 真の力を解放するマダラ。両眼から�� �� �たれし鋭き光彩はまさに剛毅果断�� �� ��たマダラの計画遂行を待ちわび�� �と 意志を示すが如く、月につぼみを神�� �� �。「輪廻の力を持つ者が月に近づ�� �� ��時、無限の夢を叶えるための月�� �映 せし眼が開く」 。。。うちは一族の石碑通り、マダ�� �� �の額には「第三の眼」が開眼。 全てを否定し、忌まわしきチャ クラの無き世界を創るため...。 マダラが望んだ,「本当の夢」は今こ� �� ��に完遂した…はずだった。
An excellent opportunity came to fruition…!! Recovering the “Rinnegan” for both of his eyes, Madara unleashes the true power of the Six Paths! Both of his eyes release a sharp brilliance: they certainly feel dauntless and decisive. Madara was still not tired of waiting for the execution of his plan. As if a testament to his willpower, the Shinjyu (/God Tree) budded. 「When someone who possesses the power of the Rinne (/endless cycle of transmigration) approaches the moon, an eye will open for the sake of granting an infinite dream. Then (that wish) will be reflected upon the moon.」…In accordance with the stone tablet of the Uchiha clan, Madara awakened a 「Third Eye」upon his forehead. He negated everything in order to create a world without abominable chakra… Madara wished for 「a true dream」. (His wish) should have been immediately accomplished there…
