Karloch

Karloch, more commonly known as Karl, was a Disgraced Gradu Quinque Prevailing Demon, who later became a Half Mortal after sharing his soul with a human.
Karloch was well known in the world of Angels and Demons, due to his Disgraced status. This lead to him becoming infamous amongst both sides and commonly named Karloch The Disgraced. Karloch was made disgraced when he attempted to steal The Curse of Hades. After failing to steal the curse, he was then captured and sent to the prisons of hell, where he sat for centuries, before finally escaping prison and successfully stealing the curse, and then going into hiding in the Mortal world. This caused the Dark Lord to place a bounty on Karloch's head, making him the most wanted of all the demons.
Karloch's bounty would later increase after breaking the strictest rule of the Demons, sharing one's soul with a mortal.
