Powers and Abilities
Essence is a being composed of shadows or some sort of dark mist and has thus shown the ability to render herself intangible and disperse into a shadowy form at will. She has been shown to be partially vulnerable to energy projection of some kind, which is seen clearly when she is affected by Starfire's energy blasts. While these were enough to slow her down and cause her pain, they did not have the ability to incapacitate her. She also contains the knowledge behind the application of many dark secrets of the All-Cast and the Untitled and she is also seemingly immortal.
