Must be a defining trait - Characters with access to vast powers (i.e. magical spells, advanced technology, genetic engineering, etc.) who are theoretically capable of this superhuman feature or ability - but whom have neither made regular use, nor provided a notable example, of this extraordinary or supernatural feat - are not listed here.
This category is for listing of fictional characters who can create, shape and manipulate darkness and shadows. By itself, darkness is mostly used to cloud everything into total darkness, but by accessing a dimension of dark energy it can be channeled to a variety of effects, both as an absence of light and a solid substance: one can also control and manipulate the beings that exist there, create and dispel shields and areas of total darkness, create constructs and weapons, teleport one's self through massive distances via shadows, etc.
