Fugaku Uchiha

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

Personality and Abilities
As leader of the Uchiha, Fugaku was focused on the clan's interest and welfare. His son, Sasuke, saw him as an stern and uncaring man (though his wife revealed he cared deeply for his youngest child) while he was seen as a father 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 while leaving little focus on Sasuke, earning Sasuke's resentment. Like many of the Uchiha, Fugaku was a highly skilled shinobi as well as a user of their bloodline trait, the Sharingan.

Background
According to Madara Uchiha, when the Nine-Tailed Demon Fox incident occurred, the village accused the Uchiha clan of orchestrating the attack. 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 control Konohagakure. 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. Fugaku later showed Sasuke how to perform the Fire Release: Great Fireball Technique. However, when Sasuke couldn't do it, Fugaku told Sasuke that it was possibly too soon for him to learn that jutsu.

Because of Fugaku's focus on Itachi, Sasuke questioned if his father ever loved him. However, Sasuke's mother ensured him that he focused on Itachi mainly because Itachi will eventually lead the clan. Sasuke's mother told Sasuke that when the two were alone, Fugaku talked a lot about Sasuke. Sasuke continued to try the Great Fireball jutsu in an attempt to impress his father and be recognized as an adult. After Sasuke finally mastered the Great Fireball Technique (in a week after his first attempt), Fugaku advised him not to follow in Itachi's footsteps, and instead to find his own path. Fugaku was later found next to his wife, dead, killed by Itachi after he gained the Mangekyo Sharingan.

Trivia

 * In the Viz Media translation of Volume 25, in the character introduction, instead of the katakana for "Fugaku," they show the characters for "Sasuke's Father."
