Epic fail, Obito stated Uzumaki to be of Senju DESCENT, which means Senju came first and Uzumaki later on, Senju themselves came from the Younger Son of Sage, meaning all these threads often made are pointless and I wonder why do they even get 5 stars or something since they contradict the very canon. Too long to read: since Sage was the original bloodline (merger of what would once become the Uchiha and Senju) and the Uzumaki are something like 50th cousins to Senju, he couldn't be one. Hell it's more probable he was a Hyuga if anything...
