Acid, once Nick Vilez a drug peddler in the Rogue Isles. He made his deals with the Vario family, a family of powerful mafioso's. Nick met his fate when he was way behind on his payments and Lenny Vario, leader of the family ordered his execution. He was brought to a warehouse, beaten to a pulp and dropped into a vat of acid. Somehow Nick's cell structure accepted the substance and was risen out, skinless, his skull dripping with acid. The Vario's were vaporized and the warehouse was left in a burning heap. He now has become the smoldering monster we now know as Acid!
