Joaquin Torres is seventeen years old living somewhere between Tuscon, AZ and Sonoita, AZ. He came to America from Mexico illegally with his mother and grandmother when he was a young boy. Joaquin is a Samaritan, one who runs food, water, and medicine to broder crossers so they don't starve or die before they reach their destination.
On a border run delivering water, Joaquin was abducted by the Sons of the Serpent and delivered to a lab in New York operated by Dr. Karl Malus. When Joaquin's grandmother, Mariana, made a request to Captain America on the news to look into his disappearance, Sam Wilson investigated and was captured himself. Malus experimented on them both. Sam's transformation into Cap Wolf was temporary. However, splicing Redwing's DNA irreversibly onto the younger man's, Joaquin was permanently changed into a falcon/human hybrid complete with arm wings, falcon eyes, and telepathic connection to Redwing. Also, due to Redwing's vampiric nature from his run-in with Baron Blood, Joaquin's regenerative abilities prevent his transformation from being reversed.
While recovering in the hospital from Malus' experimentation, Misty Knight and Dennis Dunphy took turns watching over him. Joaquin proved to be a bit of a handful on a couple of occasions, having taken to flying around the hospital whenever he became bored. As Sam Wilson continued his investigation into Malus and the Sons of the Serpent, he came into conflict with Viper and Serpent Solutions. Discovering he and Redwing shared a telepathic link with Sam, Joaquin sensed Sam in danger and flew out a hospital window and arrived in time to catch Sam in mid-fall after he had been pushed out a window. With Sam paralyzed by Asp, Joaquin had to fight off Serpent Solutions by himself until he received help from Diamondback, Misty Knight, and Demolition Man. After Viper and his group had been defeated, Joaquin designed his own costume and declared himself the new Falcon.
