Hawks, whose real name is Keigo Takami, is a prominent pro hero who held the rank of Number Two hero prior to the events of the final season. His background is marked by a difficult childhood in a troubled household, from which he was eventually removed and taken under the wing of the Hero Public Safety Commission. This organization raised and trained him from a young age to become a professional hero, a path that left him with little experience of a normal life outside of his duties.

In terms of personality, Hawks is typically depicted as laid-back, confident, and somewhat cocky, often carrying himself with a casual demeanor that can make him seem out of touch. This relaxed attitude, however, belies a sharp intellect and a deep-seated pragmatism. He is willing to make morally complex and difficult decisions for the sake of the greater good, a trait that defines much of his role in the story. His ultimate personal goal is not glory in battle, but a future where heroes have so much free time that they become a bit lazy, reflecting a desire for a peaceful society that doesn't rely so heavily on its protectors.

Hawks' primary motivation throughout the final season is to dismantle the looming threat of the Paranormal Liberation Front, a massive coalition of villains. His role in this conflict is predominantly that of an undercover spy. To gather critical intelligence, he infiltrates the ranks of the League of Villains and the Meta Liberation Army, feeding information back to the heroes and the Public Safety Commission. This espionage work is dangerously effective, as he uses his abilities to listen in on conversations and sense presences from a distance. His mission forces him into direct confrontation with the villain Twice, leading to a tragic and pivotal moment where Hawks kills Twice to prevent him from using his quirk to create an unstoppable army, an act that weighs heavily on him.

Key relationships significantly influence Hawks' development. He has a deep respect for Endeavor, the Number One hero, and often acts as a supportive partner in battle, even using his feathers to enhance Endeavor's speed and combat effectiveness. He also forms a meaningful bond with the young hero-in-training Fumikage Tokoyami, whom he takes on as an intern. This relationship is crucial as it demonstrates Hawks' capacity for genuine mentorship and care, and Tokoyami later becomes a vital ally. His encounter with Lady Nagant, a predecessor who was broken by the corrupt system of the Hero Public Safety Commission, also profoundly impacts him, opening his eyes to the need for systemic change.

Throughout the final arc, Hawks undergoes a significant transformation. His experiences, particularly the immense toll of his undercover mission and the losses he suffers, strip away much of his initial charisma, revealing a more serious and emotionally burdened individual. At the climax of the final battle against All For One, he makes a sacrificial move to protect Tokoyami. In doing so, All For One steals his quirk, Fierce Wings, permanently depriving him of his power. This loss is a major turning point. After the war and a subsequent eight-year time skip, he reappears not as the winged hero Hawks, but as Keigo Takami, the new president of the Hero Public Safety Commission. Now quirkless, he dedicates himself to reforming the hero system from within, using his political power to create a more just and humane environment for heroes and to address the societal discrimination that fuels villainy.

His notable abilities, before he lost them, were all derived from his quirk, Fierce Wings. This power granted him a massive set of scarlet wings whose individual feathers he could control telekinetically. He used these feathers as razor-sharp projectiles, combined them into larger blades, or used them to carry civilians and allies with immense strength. The feathers also granted him an extraordinary level of spatial awareness, allowing him to feel vibrations in the air to listen to distant conversations and detect movements in his surroundings. His overall speed was ranked as S-Class, making him one of the fastest heroes in existence, capable of breaking speed records to provide rapid support in battle. The primary limitations of his quirk were a finite number of feathers, which took approximately two days to fully regenerate, and a critical vulnerability to fire, which could instantly burn his wings away.
