Fugaku was the leader of the Konoha Military Police Force, the father of Itachi and Sasuke Uchiha, and leader of the Uchiha clan. His wife’s name was Mikoto Uchiha.

As leader of the Uchiha, Fugaku was focused on the clan’s interest and welfare. His son, Sasuke, saw him as a stern and uncaring man (though his wife revealed he cared deeply for his youngest child) while he was seen as a father figure to the rest of the clan. As Itachi was his successor as head of the clan, Fugaku spent much of his time focusing on the development of his eldest and little time with his youngest. Sasuke trained constantly in order to get his father’s attention and approval. Near the end of his life, Fugaku had switched his attention to Sasuke, having lost hope in a wayward Itachi. He is only impressed by great feats and rarely praises anyone, having high expectations. Fugaku is very serious, hardly smiling most of the time.
