This is why Kakashi raised himself for the most part, growing up through hardcore training and keeping his friends and team mates close to chest. Kakashi’s mother died when he was very young, and his father had gone through one of the most tragic stories due to him abandoning his duties to save his friends and companions who later vilified him for doing so. Which should already tell you just how big of a powerhouse Kakashi is. He’s essentially smarter than Shikamaru Nara, has better smelling than Kiba, is better at using the Sharingan than Sasuke and is much better at taijutsu than Rock Lee. He was a high skilled expert in all sorts of ninjustu ever since he was a child. Kakashi has maybe chakra reserves, larger than anyone else other than the new generation including Naruto in his full strength. One thing leads to another and Obito ends up getting fatally wounded, yet with his dying breath he gives Kakashi his Sharingan as a parting gift to his best friend. Fast forward to the arc where Rin went missing near the Hidden Stone Shinobi. One day, his team brought him gifts yet Obito forgot. This team was around at the time of the third great ninja war, and was very efficient in doing whatever they did. His other team members were Rin Ohara and Obito Uchiha both of whom he adored as family. When he was young, Kakashi was part of Minato’s team.
