Fugaku Uchiha

was a jōnin and head of both Konohagakure's Uchiha clan and Konoha Military Police Force.

Background
When Itachi was four, Fugaku decided to take Itachi to see mountains of corpses resulting from the Third Shinobi World War, hoping it would help his son mature quickly. While he succeeded in his goal, Itachi's maturity took a different route than Fugaku hoped.

In the anime, when Minato Namikaze was chosen as the Fourth Hokage, Fugaku was among the shinobi present atop the Academy, suggesting he was a highly respected individual amongst the village.

With the Nine-Tails' attack on Konoha, 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 became a double agent, leaking information right back to the village.

As Itachi was the eldest of his sons, and hence, the successor of the clan, 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, leading Fugaku to shift his attention to Sasuke, even teaching him how to use the Fire Release: Great Fireball Technique, and was impressed at how Sasuke was able to master the technique after just one week. Sasuke was finally able to enjoy his father's company, but Fugaku advised him not to follow in Itachi's footsteps. During the Uchiha Clan Downfall, when Itachi confronted his parents, Fugaku and Mikoto did not resist and told Itachi that they were still proud of him and to promise to take care of Sasuke before they let Itachi kill them. Fugaku was later found laying dead on top of his wife's corpse.

Personality
As leader of the Uchiha, Fugaku was focused on the clan's interest and welfare and had a strong sense of responsibility. 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 the wayward Itachi. He was only impressed by great feats and rarely praised anyone, having high expectations. Fugaku was very serious, hardly smiling most of the time. He also had a short temper, easily getting angry at Itachi for trying to deny an important mission in exchange for attending Sasuke's Academy 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 was in truth resentful of how the village did not trust and shunned the clan mistakenly for the Nine-Tails' Attack on Konoha. His anger for that had taken as far as to plan a coup d'etat, which would lead to a potential Fourth Shinobi World War.

While outwardly Fugaku seemed strict and neglectful towards his eldest and youngest sons respectively, coupled with his devotion and focus of his clan's supremacy and welfare leading him to seem hateful and non-negotiable (which led Sasuke to see him as stern and uncaring), he was still a very caring individual to his sons (as his wife correctly stated to Sasuke) as he told Itachi despite the fact he took Konoha's side over the Uchiha's, he was still proud of him. According to Mikoto, when she and Fugaku are alone, Fugaku would mostly, if not only, talk about Sasuke.

Despite Fugaku's love for his wife and children, he was apparently unable to overcome his clan's curse, which ultimately led to his death. Stemming from this, when Itachi attempted to persuade his father to stop the coup d'tact, the cries fell on deaf ears and he simply told Itachi he was being arrogant.

Fugaku did seek to motivate Sasuke despite not realising Sasuke wanted him to acknowledge he was his son instead of telling him he'll be a splendid shinobi like his brother, which actually hurt Sasuke rather than making him happy. He loved both his sons dearly and rather than resist death, he and his wife willingly allowed Itachi to execute them and asked Itachi to take care of Sauske.

Appearance
Fugaku had short, black hair that reached to his shoulders and onyx-coloured eyes, with visible creases below them made more pronounced whenever he adopted a stern look (both of which Itachi inherited from him). He wore a simple kimono with grey pants which had the clan's symbol on the back when not on duty. While on duty, he wore the standard flak jacket, along with a black shirt with the Konoha Military Police Force symbol on the shoulders, shin-guards and a black, open-front apron with white diamonds on the bottom.

Abilities
As the leader of the Uchiha clan and the Konoha Military Police Force, Fugaku was likely a formidable shinobi and well-versed in all of his clan's techniques. His intelligence was noted by Danzō Shimura as one of the greatest in generations. Fugaku's skills were held in high regard by his fellow clansmen as they felt Fugaku should have been a contender for the Fourth Hokage alongside Minato Namikaze and Orochimaru.

Ninjutsu
Fugaku was supposedly quite skilled with shuriken, as Sasuke noted that Itachi was very skilled with shuriken, even more so than their own father. As an Uchiha, he had a natural affinity for Fire Release, showing great mastery of the clan's signature Great Fireball Technique, which he taught to Sasuke.

Sharingan
Like most members of his clan, Fugaku possessed the Sharingan. The dōjutsu granted him the ability to see chakra, predict movements, and place victims under genjutsu with a single glance. His accomplishments during the Third Shinobi World War earned him the nickname of, presumably for his prowess with the Sharingan. He also had some knowledge about the Mangekyō Sharingan, after telling Sasuke that it needs a great sacrifice to awaken.
