Fugaku Uchiha

was the leader of the Konoha Military Police Force, the father of Itachi and Sasuke Uchiha, and leader of the Uchiha clan.

Background
When the Nine-Tailed Demon Fox attacked Konohagakure, the village accused the Uchiha clan of orchestrating the attack (during the attack, Itachi noted that Fugaku and his wife were noticeably absent before the beast struck - what they were doing is currently unknown). This belief caused a rift between the village and the Uchiha clan. Fugaku, out of spite, conspired a coup d'etat that would allow the Uchiha clan to take control of the village. Eventually, Fugaku placed Itachi as a spy in the ANBU to pass information back to the clan. However, Itachi secretly betrayed the Uchiha and took the role of a double agent, leaking information right back to the village.

As Itachi was the oldest of his children, Fugaku focused most of his attention on him, even defending Itachi when he was suspected of killing Shisui Uchiha. However, the two had a falling out when Itachi lost hope in the clan and Fugaku shifted his attention to Sasuke, even teaching him how to use the Fire Release: Great Fireball Technique, and was impressed at how the boy was able to master the technique after one week. Sasuke was finally able to enjoy his father's company, but Fugaku advised him not to follow in Itachi's footsteps. Fugaku was later found on top of his wife, dead, killed by his eldest son Itachi during the latter's massacre of the Uchiha clan.

Appearance
Fugaku has short, brown hair and onyx eyes (when the Sharingan is not activated), with visible creases below them made more pronounced whenever he adopts a stern look (similar to his son Itachi). He wears a black robe with gray pants with the clan symbol on the back when not on duty. While in his jōnin uniform, he wears the standard ninja vest, a black t-shirt with the Konoha Military Police Force symbol, and a black cloak with white diamonds on the bottom that stops just before his ankles.

Personality
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. He also has a short temper, easily getting angry at Itachi for trying to deny an important mission in exchange for attending Sasuke's school initiation, and for refusing to attend an important clan meeting.

Despite his outward attitude of desiring to strengthen the bonds between the Uchiha clan and Konohagakure, Fugaku is in truth resentful of how the village had shunned the clan for years, particularly after the Nine-Tails' Attack on Konoha. His spite has taken as far as to plan a coup d'etat, which would lead to a potential Fourth Great Shinobi World War, and he was apparently unwilling to negotiate with Konoha's elders, forcing the Uchiha's assassination.

Abilities
As the leader of the Uchiha clan, it is likely that he is well-versed in all the clan's techniques. He taught Sasuke the clan's signature jutsu, the Fire Release: Great Fireball Technique demonstrating great mastery of the technique. It is seen in Part I that he has the Sharingan, similar to most members in the Uchiha clan. Also, being the leader of the Konoha Military Police Force, it can be said that he is very intelligent and a formidable opponent in battle. He also had some knowledge about the Mangekyō Sharingan, telling Sasuke that it needs a great sacrifice to awaken.

Trivia

 * In the character introduction of Volume 25, he is credited as "Sasuke's Father" rather than "Fugaku Uchiha".
