This is someone we will most likely never get to see in action from the Naruto world. The father of Hatake Kakashi, Sakumo Hatake is one of the strongest ninja in the story yet we never see him fight.
This is incredibly odd considering he was legendary throughout the shinobi world as the Whit Fang of The Leaf, due to his incredible skills and dangerousness he was so feared ninja fled when just gazing upon him.
Sakumo was so powerful that his strength was stated many times, to be greater than the legendary Sennin in Tsunade, Jiraiya and Orochimaru.
All we know of him was that Sakumo is that he was later disgraced by the village and as a result committed suicide because of it.
Sakumo fell into a great depression after he abandoned a mission in oder to save his comrades from death, during the third great ninja war. As a result the village was later attacked and afterwards he was hated by the village and labelled a coward for disobeying orders.
Sadly even the comrades he saved resented him and so he took his own life and even still after this, was buried separately from the other villagers and with no tombstone.
It was an incredibly sad end for a hero of the village but with him being so powerful and well known all over the world, its still surprising we never got to see his skills in action.
Not in life or in death, as when the fourth great ninja war started, he wasn’t reanimated and brought back to life by Kabato.
Kabato brought many deceased legends back to the world of the living and forced them to fight for him, but oddly enough left out Sakumo despite his power.
This was never explained, especially considering it would have been easy to obtain DNA from his buried corpse in oder to reanimate him.
All we know is that Saumo Hatake was one of the strongest shinobi to ever live, but sadly we never got to see it.
