The Poison Demon - Pascal LeBlanc

One of the rare forms of demon that started out as human. In his previous life, he was an orphaned Italian-American soldier who was part of a unit that specialised in tracking and deposing of any Nazi activity that revolved around Hitler's involvement in the occult. During his most recent mission in 1945, he and his team were assigned to take down a group of Nazi Scientists that were devolving a gateway to another dimension, and while history denied the events that occurred that night, Pascal LeBlanc suffered a terrible fate when he and his team infiltrated that warehouse. When the Nazi in charge of the facility resisted arrest a fight ensued between the two soldiers and the gateway was activated, and while nothing physical emerged, two demonic entities burst out of the vortex and consumed the two soldiers, turning them both into hideous creatures with unique abilities. In Pascal's case, he became a sickly creature that constantly exhaled a lethal poison to anyone, human or demon. After escaping his fellow soldiers and obtaining a modified gas-mask that contains his dark magic and his breath, he now travels the world in his immortal state.
