Dark Shadow (黒影ダークシャドウ Dāku Shadō?): Fumikage's Quirk allows him to manifest a sentient shadow monster from his body that he can materialize and contract freely. Dark Shadow's energy is limited and can be drained by bright light. Dark Shadow retracts into Fumikage's body when it runs out of energy. The shadow entity's personality, strength, defense, and control depend on the lack of light. In bright light, Dark Shadow is weaker and smaller but still has considerable strength and defense.
