Fumikage Tokoyami possesses a distinctive bird-like head resembling a crow or raven, featuring a tan, hooked beak, red eyes positioned on either side, and black feather-like hair. His body maintains a human form with fair skin. His U.A. High School hero costume included a dark robe appearing purple under light, knee-high boots, and a utility belt, later revealing a dark shirt and baggy pants underneath. As an adult Pro Hero, his appearance evolved to include scruffier, gray-tinted feathers, several rings, and wrist chains. A scar marks his left foot from injuries sustained during the Paranormal Liberation War. Personality-wise, Tokoyami is reserved, serious, and introspective, often employing dramatic, archaic language reflective of his affinity for dark themes and self-identification as a "creature of the dark." Despite initial insecurity about his interests, he demonstrates humility, recognizing his limitations and valuing self-improvement. He forms strong bonds with mentors like Hawks and peers, displaying fierce protectiveness when allies are threatened. His emotions, particularly anger or regret, can destabilize his Quirk, though he gradually masters this volatility. Tokoyami’s Quirk, Dark Shadow, manifests as a sentient shadow entity tethered to him. Its strength, size, and controllability fluctuate with environmental light: it weakens in bright conditions but grows immensely powerful—and unruly—in darkness. Negative emotions amplify its power at the cost of control. Early struggles included a rampage during the Forest Training Camp, where Dark Shadow defeated the villain Moonfish uncontrollably. As a U.A. student, Tokoyami ranked among Class 1-A’s strongest combatants. He placed third in the U.A. Sports Festival, contributing significantly to Izuku Midoriya’s cavalry team by defending against Katsuki Bakugo’s explosions and stealing Shoto Todoroki’s headband. He passed practical exams through teamwork, such as handcuffing Ectoplasm with Tsuyu Asui’s assistance. His mentorship under Hawks during a work-study program enhanced his physical conditioning and Quirk mastery. He developed techniques like Black Fallen Angel for high-speed flight and Black Abyss, an armor-like fusion with Dark Shadow mitigating close-range weaknesses. These improvements enabled him to overpower opponents like Kinoko Komori and Shihai Kuroiro during joint training. In World Heroes' Mission, Tokoyami participated in a global operation against the terrorist group Humarise. Deployed to New York alongside Hawks and Team Shishido, his role involved raiding a Humarise branch to secure Trigger Bombs and apprehend members. During the Paranormal Liberation War, Tokoyami showcased advanced Quirk control. He immobilized Re-Destro using Ragnarök, a colossal manifestation of Dark Shadow that exploited the villain’s prosthetic weaknesses. He later rescued Hawks from Dabi’s flames. In the Final War, he aided Hawks and Kyoka Jiro against All For One, destroying the villain’s helmet with Fleeting Blow and utilizing storm-darkened skies to achieve Dark Shadow: Total Release, a massive form that momentarily overwhelmed All For One until the villain’s Rewind ability negated it. Eight years post-war, Tokoyami graduated as the No. 17 Pro Hero. His abilities solidified him as a peer to top heroes like Midoriya and Todoroki, balancing Dark Shadow’s destructive potential with refined tactical acumen. His journey shows continuous growth from a student reliant on darkness to a hero mastering its depths.
