Fumikage Tokoyami is a reserved, serious figure marked by a striking bird-like visage—a sleek black avian head reminiscent of a raven, crimson eyes, and a tan beak. His humanoid frame boasts fair skin, clad in a dark purple-tinted black robe, knee-high boots, and a crimson choker. Intensive training later sculpts his physique into a more muscular build, and he sustains a scar on his left foot from Dabi’s flames during the Paranormal Liberation War. His Quirk, Dark Shadow, is a sentient shadow entity that manifests for combat, defense, and mobility, showcasing his tactical acumen. The entity’s power shifts with ambient light: growing volatile in darkness and docile under brightness. This duality demands meticulous control, exemplified during rescue training when Fumikage avoids deploying Dark Shadow in a precarious, darkened structure to avert chaos. Emergency lighting later stabilizes the entity, enabling precise aid. Fumikage merges noble intentions with a chūnibyō-esque fascination for darkness and theatrical dialogue. Humble yet driven, he acknowledges his weaknesses while relentlessly refining his skills, as seen when interning under Hawks. There, he hones Dark Shadow’s range and devises techniques like Black Fallen Angel. His resolve to shield allies surfaces in pivotal battles, from risking his life to save Hawks from Dabi to uniting with peers against All For One. During the Provisional Hero License Exam, Fumikage faces a simulated disaster rescue scenario alongside Shoto Todoroki, maneuvering through collapses and hazards with adaptability. Trapped in darkness, he opts for restraint over reckless Quirk use, later leveraging restored light to steady Dark Shadow and support allies. These choices highlight his advancing teamwork and crisis management. As the No. 17 Pro Hero post-graduation, he sports a rugged appearance—gray-tinged feathers, rings, and chains. His Quirk evolves to unleash "Total Release," a colossal Dark Shadow form deployed against All For One in the Final War, signifying his mastery. This trajectory underscores his resilience, blending shadow-wielding prowess with an unwavering heroic ethos.
