Hugo Martinez

Hugo Martinez is the main antagonist of the 2019 film Rambo: Last Blood. He is the leader of a drug cartel (along with his brother, Victor Martinez) and who is responsible for kidnapping Gabrielle and causing her death.

He was portrayed by Sergio Peris-Mencheta.

History
Hugo and Victor Martinez together kidnap and hold Gabrielle hostage in a club while in Mexico. Rambo travels to Mexico and interrogates both Miguel and Jezel about Gabrielle's whereabouts. Jezel reluctantly leads Rambo to the club where Gabrielle was last seen and confronts El Flako, the man who last spoke with Gabrielle.

El Flako leads Rambo to the location of the kidnappers while being followed by a mysterious woman, not before being immediately confronted and beaten by the cartel. They steal his driving license, getting to know the locations of Rambo's farmhouse and a photo of Gabrielle, whom Victor recognizes. The cartel vow to mistreat Gabrielle further due to Rambo's actions.

The mysterious woman reveals her identity as Carmen Delgado, who is an independent journalist reporting the deeds of the Martinez siblings who had kidnapped and murdered her sister. Rambo later raids the brothel, killing several men until he finds a drugged Gabrielle. On the way back home, Rambo thanks Gabrielle for giving him hope for ten years before she dies from the forced overdose.

Rambo sends Maria away and rigs the ranch with traps for a confrontation, later returning to Mexico to ask Carmen's help in finding Victor. Carmen refuses initially, believing it will solve nothing but is convinced after Rambo appeals to her grief and frustrations.

Rambo raids Victor's home, killing several guards and decapitating Victor. In retaliation, Hugo leads a group of hitmen to Rambo's ranch, where each falls victim to the rigged traps during a bloody shootout. Saving Hugo for last, Rambo pins him to the wall of his barn by firing arrows into his limbs, then stabs him in the chest with a large knife before slowly cutting his chest open. As Hugo screams in agony, Rambo tears out his heart with his bare hand and forces him to watch it stop beating. In the aftermath, a weakened Rambo sits on the porch of his father's house, vowing to continue fighting and to keep the memories of his loved ones alive.

Trivia
