João Pereira, codenamed Dengoso, is a side character featured in Tom Clancy's Ghost Recon Wildlands and possibly one of the youngest brothers in the Pereira family.
Joao was sent on an undercover operation in the Santa Blanca Drug Cartel. With his cover blown, he was subsequently kidnapped and disappeared. This resulted in his older sister, Rainbow Operator Caveira going AWOL and traveling to Bolivia in order to find and rescue him. Rainbow Operators Valkyrie and Twitch collaborated with Ghost Recon to conduct Operation Archangel in order to recover Caveira.
