Camilla Reyes (played by Leonor Varela) is the main villainess from "0-8-4," the second episode of Season One of Marvel's Agents of SHIELD.
She is the commandant of an army in Peru, where the S.H.I.E.L.D. agents head to in order to retrieve a dangerous weapon simply known as "0-8-4." After an attack, Coulson and his agents take Camilla and her army to safety in their plane, but while there, Coulson discovers that he and his agents are being set up by Camilla and her army, leading to a confrontation. At that moment, Camilla subdues Coulson, while her cohorts capture the rest of the agents.
Camilla's evil plan: to take possession of 0-8-4 for herself and use it to rule over her entire army. Her plan is eventually thwarted, and while Coulson does save Camilla from being flown off the plane, he does subdue and hold her captive.
