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. When it runs out of energy, Dark Shadow retracts back into Fumikage's body. The personality, strength, defense, and control of the shadow monster depends on the lack of light. In bright light, Dark Shadow is weaker and smaller in size, but still has considerable power
