Dark shadow, manifest a sentient shadow monster from her body that she 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 Emily'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 strength and defense and is easier to control. In total darkness, Dark Shadow is much bigger, which grants it far greater strength and defense. It is even powerful enough to rip out and cut down multiple full-grown trees with ease. However, Dark Shadow is more difficult to control in the dark, causing it to rampage based on its own free will. This Monster like shadow may also control her emotions, and actions.
