Had Dan Kato lived and become Hokage, had Minato not been the one to rescue Kushina, Naruto would become something of legend. Here is that legend. Naruto Uzumaki, son of Yagura and Kushina, Jinchuuriki to the Three-Headed Guardian Beast, and master swordsman. Slight Devil May Cry Crossover. Not a Major crossover.

Had Kaguya Otsutsuki held a physical manifestation, would she have attempted to take over the world? Or would she have disguised herself as Kushina Uzumaki, and birthed a child to be trained by the greatest shinobi, initiated into Akatsuki, and become the Child of Prophecy who would unseal her from her hellish prison? Minor Crossovers inside. Mainly with horror icons for Halloween

What if... What if Naruto had been born just a few years early? What if he had been born that same day as Itachi Uchiha? What world would be derived from such a small change?
