6. Hajime awakened his sharingan when his best friend Hitomi was trying to get him free from a trap in a cave. He was fighting an enemy shinobi just as Hitomi was fighting another one outside the cave. He knew from deduction that the enemy was only going to be weak to extreme forms of Taijustu, water style ninjutsu, and genjutsu, neither of which he possessed. He forced himslef to awaken the sharingan to be able to allow Hitomi to free him.

Hajime mainly uses genjutsu with his sharingan. He has mastered genjutsu with his sharingan in a way his dad never could. (His father is Ichiro Uchiha)

Additional information: Hajime was born to Ichiro Uchiha and Anna Richi. Ichiro decided to give him the Uchiha last name before a few Uchiha came to him and said that a half Uchiha wasn't a true Uchiha. They demanded all ties be cut with both Ichiro and Hajime. Hajime, in their eyes, was no good then dirt for not being a true uchiha. This is why Itachi skipped him. He was unaware of his existance as an Uchiha.
