This shinobi was the leader of the Uzumaki clan during the time of the founding of the first hidden shinobi village, Konohagakure.
In the anime it was shown that at some point in time, he met with Hashirama Senju and other members of both their clans in order to seemingly deal with a gigantic beast. Using his prowess in fūinjutsu the Uzumaki's leader was able to seal away the beast.
The Uzumaki clan leader is depicted as being older than his counterpart, Hashirama Senju. He was shown as having long, white hair, and a square goatee. He also wore armour reminiscent of the period of dress. The shoulders of his robes bore the crest of their home village, which likely inspired its incorporation into Konohagakure shinobi uniforms. On his back were what appears to be the curved handles of two swords which in the anime were shown to be bandaged up.
Like all members of his clan, he specialised in the use of fūinjutsu, which as seen in the anime was proficient enough to seal a beast within moments. He was also probably skilled in kenjutsu.
