Born 1973, Rego had joined the Brazilian army but was decommissioned in 2006 due to his mental status. Following his dismissal from the Brazilian army, Rego joined the Crachá Preto militia, soon becoming the underboss of the militia, and Neves' right-hand man, as well his closest associate. In 2010, during a vigilante attack on the Purgatópolis favela, Rego was caught and tortured by three gang members, leaving both his face and personality scarred.
