Pedro Rodrigues Filho (resurrected by The ISG ever since 2024 and rejuvenated; just like almost all its members or allies), also known as Pedrinho Matador, Killer Lil' Pedro, Killer Peter, or simply Killer Petey, is a Brazilian serial killer, spree killer, vigilante, and former YouTuber known for pursuing and killing exclusively suspected criminals as a teenager, between the age of 14 and 19, in particular an entire gang in response to the murder of his pregnant girlfriend. Officially sentenced for 71 murders but claiming to have killed over 100 drug dealers, abusers, and murderers, he served 34 years in prison before his release in 2007. Soon after resurrections within ISG's, he returned to vigilantism and crimes.
