Who would win out of the the Uzumaki clan V Senju. By the time Naruto is Hokage rougly 35% of the Hokages would have been from the Uzumaki clan ( Yondaime and Naruto) and 40% from Senju ( Shodaime, Nidaime and Tsunade).
Absurdly high chakra, enough to summon Gamabunta (4th Hokage)
Unrivalled ability to manipulate the shape and Nature and chakra i.e. Fuuton Rasengan, Kyuubi control and Senjutsu chakra manipulation.
Ability to seal the Kyuubi (thus robbing Kyuubi controllers such as Madara and Shodaime of the oppurtunity to controll the Kyuubi). However the entire Chakra on the Kyubi can not be sealed without using the shinigami technique.
High speed (naruto) and teleportation (yondaime).
High strength and stamina.
Ability to seal the Kyuubi (this isn't the same as using the Kyuubi i.e. Shodaime cannot neccessarily set the Kyuubi lose, he can prbl only supress it like yamato, furtheremore even if he could use the Kyuubi this would prove impossible as the Uzumaki's currrently control the Kyuubi, the 4th with having sealed half its chakra within his son).
Mokutun ability (shodaime).
Water element (Nidaiem)
Water and earth element supposedly (Yammato claims both are needed to create mokutun)
High strength an stamina.
The Senju were powerfull enough to dominate the Uchihas including Madara who was decisively defeated by Senju Hashirama. But The Uzumaki's are positioned to be more powerfull. For instance the 4th is considered to be the most powerfull of Hokages along with Sandaime. Yes thats right, Yondaime is confirmed by Kishi to be even more powerfull than Senju Hashirama, the man who ruined Madara. So powerfull that he managed to turn the tide of the third great War. So great that NInja were told to flee rather than fight him. Then there's the small matter of Naruto. Did I say small. Yes. And by small I mean large. By the time Naruto is Hokage he would be the most powerfull Shinobi. Take a deep breath and contemplate what that means. More powerfull than Hashirama. And even more powerfull than his father, a man considered in a different league than even Shodaime.
In a battle Royale between the Uzumaki's and Senju featuring Nidaime, Shodaime and Tsunade V Yondaime and Naruto (when he's Kage) i'd say the Uzumakis win. The battle could be won in several ways. I.e. Yondaime could seal part of (but not all of the Kyubi's chakra within himself or his son using the Shiki Fuiin sealing technique ( AND NOT THE DEATH GOD TECH AS THAT WOULD TRAP HIM WITHIN THE DEATH GOD REALM). A second option could be to use his flying Thunder God Tech on Shodaime. As for naruto he could just sit there and count sheep...joke.
