Their last known confrontation with MERGE was down in Colombia, involving one of its kingpins, a Bolivian drug lord named El Tiburon. His organization, known as "El Dorado", had an association with the Colombian cartels and had been selected by MERGE to handle their latest enterprise: coordinated attacks against law enforcement teams dedicated to stopping the drug trade. To this end, El Tiburon formed an alliance with a Cuban military officer named Major Pescador. Phoenix Force invaded El Tiburon's lair and ended the scheme. During this mission, Rafael Encizo found his long-lost younger brother, Raul Encizo, who had become a Communist and was helping Maj. Pescador in his work with MERGE.
