Juliana Calderon (step-mother/wife, later ex-wife possibly deceased)
Gustavo Calderón was the president of San Marcos when a civil war broke out. To fund the war, he arranged a trade with the CIA. However, the war left him clinging to power, and eventually ended up in prison for three weeks. He escaped from prison, only to be mauled to death by a tiger.
President of San MarcosEdit
At some point, a civil war broke out. The war drastically affected Calderón's influence, leaving him clinging to power. To that end, Calderón arranged a trade for the CIA; Calderón would offer his country's cocaine supply to the United States, who would in turn provide him with weapons and armaments to allow his soldiers to continue to fight the Communist rebels threatening his presidential power.
To the public, Calderón was seen as very caring of his people, even going to the hospital to comfort a comrade who died. This however was a mere facade, as Calderón constantly expresses his relief the war was taking place far away from his palace, which was filled with an uncanny amount of priceless art and historical artifacts, all of which were paid for using his country's national funding.
He also seems to have great knowledge of United States Presidents, citing that William Howard Taft was both President and Supreme Court Justice, and that George Washington could have run for a third term if he had wanted to. He has a love for Cherlene's music, as he bought a million copies of her album, which boosted it to Platinum status, and even forced his soldiers to unload all of her CDs.
- The name Calderón could be a reference to the Calderone Drug Cartel and it's leader Esteban (and later Orlando) Calderone from the series Miami Vice, which serves as the inspiration for Archer Vice.
- Calderón's nickname "Baby Gus" is likely a reference to former Haitian dictator Jean-Claude "Baby Doc" Duvalier.
