Family is forged one step at a time (джен)

In one timeline, Madara hunted down and enslaved the Kyuubi no Kitsune to his will and wielded him against Hashirama. Two hundred years later, Naruto squares off against a man who seeks to turn back time to claim the Juubi. He wins in the sense that the man dies. He looses in that he himself is cast back in time instead, and without Kurama.
In this timeline, two now seek the Bijuu, one young, powerful, and driven by hatred; the other beyond ancient, inherently kind, and only seeks to save his oldest friend in the little time he has left, even if said friend no longer remembers him.
A one-shot that became something more.
