Rodrigo Neumann Pires, commonly known by his alias "Viking", is a Brazilian vigilante, outlaw, and murderer associated with the ISG criminal supergroup. Born into a working-class family in southern Brazil, Rodrigo spent most of his adult life as a long-distance truck driver, moving through dangerous highways and corrupt police checkpoints. His years on the road exposed him to systemic abuse, theft, and extortion by local authorities and private militias, gradually transforming him into a disillusioned and violent man. Following a fatal confrontation with a corrupt officer during a late-night cargo inspection, Rodrigo vanished from the transport industry and re-emerged months later under the name "Viking".
