Biography
The Invunche is a demonic entity that arrived on the Earth plane several years ago. It was created by a South American coven of male witches known as the Brujería. Taking the form of a twisted humanoid with a backwards head and disjointed limbs, it systematically hunted down and murdered select individuals who were close to John Constantine, including the erstwhile Newcastle Crew. It's first victim was an American artist named Emma. The Invunche manifested in her studio as an image on her sketch pad. It took corporeal form and terrorized Emma to the point wherein she threw herself from her studio window. It then murdered Sister Anne-Marie after stalking her on a train platform. . The Invunche then returned to the Brujería's Council of the Cave where it attacked John Constantine. Capturing Constantine, it dragged him down into the darkest depths of the cavern where the Brujería conducted their rituals.
