Daniel Felipe Petry, a formidable figure within the ISG supergroups, is feared for his sadistic nature, having committed heinous acts such as murder, torture, mutilation, and sexual abuses during his crimes. In 2007, he gained infamy for the brutal murder of Gabriel Kuhn, in which he engaged in horrifying acts of wrath and violence. After a hiatus from his crimes and disppearing in 2010, he made a return in 2022, motivated by the likes of Caio Henrique, Nathan Vieira, Lorena Vieira, Isabella Lopes, Maxwell Cavalcante, and others in the ISG group. Not only considering fellow Brazilian killers, he also holds huge admiration for Luka Magnotta, Jeffrey Dahmer, Belle Gorn, Nikita Lytkin, etc; all within the ISG as well.
