Marvel: Darkforce Channeling

Tyrone Johnson (Cloak)
Cloak can channel Darkforce to create a field of darkness in his general vicinity, usually using his cloak as a focal point to manipulate this darkness, though it can be spread well beyond the confines of his cloak. People enveloped by Cloak's darkness feel numbing cold and crippling fear, sometimes seeing disturbing visions. Overlong exposure to the darkness can drive people insane. Unprotected victims trapped in Cloak's dark realm are gradually drained of their life-force, and presumably die unless Cloak releases them. Dagger's light renders her largely immune to Cloak's darkness, and she can extend her light to protect others within Cloak's darkness if need be.
