Shishido, the professional "Lion Hero," ranks No. 13 on the Hero Billboard Chart. His leonine Quirk shapes his appearance: a wild mane of spiky brown hair, a costume layered with golden fur and spiked accents, a black mouthpiece evoking a lion’s snarl, and a muscular frame accentuated by razor-sharp claws. Though fiery and competitive, Shishido tempers his aggression with tactical precision, swiftly adapting to shifting battle conditions. He charges into fights with roaring intensity—pummeling foes into the earth with clawed strikes—yet prioritizes allies’ safety, insisting exhausted teammates withdraw from peril. His rivalry with Gang Orca sparks frequent clashes, but the two unite seamlessly against shared threats, such as dismantling a bank heist through combined force. The Lion Quirk amplifies his speed, agility, and raw power, manifesting in retractable claws and explosive leaps. He shatters concrete with single blows and outpaces enemies mid-assault. At the Hero League Baseball OVA, his competitive drive ignites as he hurls blazing pitches and orchestrates game-winning strategies. As a mentor, he guides U.A. students like Mashirao Ojiro and Rikido Sato through internship trials. During the Paranormal Liberation War, he storms the Villain Factory with the Villa Raid Team, confronting Liberation Front operatives. In the Final War, he battles All For One’s forces at Gunga Mountain, rallying heroes to evacuate captives from Dabi’s encroaching inferno. Overrun by Twice’s cloned swarm, he fights relentlessly until Ochaco Uraraka’s gravity Quirk scatters the duplicates. Once driven by personal glory, Shishido evolves into a leader who champions collaboration over individual rivalry. He forges alliances with former adversaries during crises and shields civilians amid chaos, cementing his reputation as a steadfast pillar of hero society.
