Warning: Godlike Naruto, but will be facing a Godlike enemy later!
What if Minato has done a better job during the sealing? Instead of Naruto receiving half of Kurama's chakra and half his soul, he receives all the chakra while Minato takes Kurama's soul into the Shinigami's stomach. What if when Tsunade learned of the attack she came and took Naruto away from the village so he could live without they're hate? She'd raise Naruto as her son, and he'd be more powerful than you could dream of!
