Fugaku led the Uchiha clan and commanded the Konoha Military Police Force, with his wife Mikoto by his side. He's best known for being a stern, serious figure—the kind of guy who rarely smiled and kept his expectations sky-high. His youngest son Sasuke saw him as cold and distant, though Mikoto later revealed Fugaku actually cared deeply for the kid; he just had a terrible way of showing it.
Most of Fugaku's attention went to Itachi, his eldest and intended successor as clan leader. That left Sasuke constantly training, desperate to earn even a scrap of his father's approval. Later in life, Fugaku shifted focus to Sasuke after losing faith in Itachi, but by then the damage was done—he only handed out praise for genuinely impressive accomplishments, which meant almost never.
Beyond his own family, Fugaku served as a father figure to the rest of the Uchiha clan, always prioritizing their interests and welfare. He was the kind of leader who demanded excellence and didn't sugarcoat things.
