Sakumo Hatake - Narutopedia, the Naruto Wiki
Like his son, Sakumo was a gifted shinobi praised for his talents in the ninja arts even by the likes of Minato Namikaze, the Fourth Hokage. In battle, Sakumo was a truly powerful shinobi, and in his time, his powers were said to surpass those of the Sannin.
The mere idea of facing Sakumo brought fear to enemies, as shown from the reaction of an Iwagakure shinobi initially believing Kakashi to be his father. His primary weapon during battle was a tantō called the White Light Chakra Sabre that would emit a trail of white chakra when swung, earning him the nickname "Konoha's White Fang". After he died, he left his tantō to Kakashi, which was later on cut in half when Kakashi fought Kakkō, an Iwagakure shinobi.
He has some similarities to Minato Namikaze, the Fourth Hokage.
Both were respected and feared throughout the world.
Both had resemblances with their sons.
Both died in their sons' youth and because of their deaths, their respective sons would later grow up to be shinobi seen as surpassing their fathers.
Both were able to speak with their sons after death.
