Kugo Sakamata, known professionally as Gang Orca, is a top-ranked hero defined by his heteromorphic Orcinus quirk. This mutant-type ability grants him the physiology of a killer whale, permanently shaping his appearance: white skin marked with black patterns, a prominent dorsal fin, deep-set white eyes with red pupils, and a powerful build. He typically wears a sharp white suit featuring a high collar resembling teeth, a pink tongue-shaped tie, and a cape reflecting killer whale coloration. Combat scenarios, such as the Provisional Hero License Exam, saw him add a red vest and metal gauntlets. Following the Paranormal Liberation War, he bore a scar over his left eye, and eight years later, displayed further scarring and wrinkling consistent with marine mammal aging. His history traces back to Horikoshi Kohei's *Oumagadoki Zoo*, where he served as an antagonist under the cruel aquarium director Isana. Initially motivated by fear, Sakamata enforced harsh policies until encountering compassionate zoo staff. Their empathy inspired his rebellion against Isana, resulting in the director's defeat. Sakamata then took responsibility for monitoring Isana to prevent further atrocities, marking his transition toward redemption. In the main continuity, Sakamata ranks among Japan's elite heroes, initially holding the No. 10 position before adjusting to No. 12 after All Might's retirement. His Orcinus quirk provides enhanced strength, durability, and speed, coupled with the capacity to generate debilitating hypersonic waves effective against opponents or obstacles. These waves diminish over distance and function optimally in aquatic environments, where his mobility and sensory capabilities peak. His cetacean biology makes him vulnerable to heat and dehydration; he carries water bottles to mitigate this during prolonged engagements. He favors a close-quarters combat style, leveraging speed to close gaps and maximize his sonic wave potency. Sakamata participated in critical operations like the Hideout Raid to rescue Katsuki Bakugo, helping subdue multiple Nomu variants. Later, as an examiner during the Provisional Hero License Exam's mock villain segment, he analyzed student tactics while simulating threats. He overwhelmed examinees Shoto Todoroki, Inasa Yoarashi, and Yo Shindo by exploiting their interpersonal conflicts. He was ultimately contained through coordinated efforts involving Izuku Midoriya and a fire-based attack, enduring the heat long enough to rehydrate. As a remedial instructor after the exam, Sakamata adopted a stern, demanding approach toward failing students like Bakugo, Todoroki, and Yoarashi, using harsh criticism and physical challenges to emphasize professionalism and teamwork. Despite this intimidating demeanor, colleagues like Present Mic noted his underlying affection for children, and he privately expressed satisfaction in student growth. His appearance ranked him third on "heroes resembling villains" polls, a stereotype he leveraged as a teaching tool against prejudice. He maintains a competitive rivalry with the lion-heteromorphic hero Shishido, showcased in events like the Hero League Baseball OVA. Their clashes reflect opposing animal traits, yet they cooperate seamlessly during emergencies, such as apprehending a bank robber mid-game. Post-war, he continued hero duties while mentoring heteromorphic students like Mezo Shoji, addressing societal bias through example.
