Jackie held the powers of the Darkness, an elemental force of chaos and creation. The core of a Darkness wielder's abilities is their accessing of an otherworldly dimension through the shadows around them and exerting control over the countless demonic creatures that dwell there. These creatures - called Darklings - usually appear as serpentine or goblinoid fiends which cause mischief and murder on behalf of their host and can communicate with their master through telepathy. They possess supernatural strength and stamina as well as deadly claws and fangs.
