Can anyone do Umbrakinesis?
Umbrakinesis-is the power of controlling darkness (also known as negatively charged particles), with the mind. The user can make the dark object solid for combat, and it can make the user pure dark energy. The technique can also be used to control shadows and darken places that are bright like a light room. This involves negative energy. Users can also move physical objects by moving their shadow.
