Childhood friends with Owen since third grade, Javier began distancing himself from his friend after Owen's father, arrested for robbing a bank, died in prison. As Javier was hiding his homosexuality, he wanted to avoid dealing with Owen's issues on top of his own. Around 2015, however, Javier came out to his family who were ultimately accepting, which allayed his fears that their Catholic and Baptist backgrounds would mean otherwise but his brother Mani ended up in jail after assaulting a man for calling Javier a "faggot".
About a year later, Javier was approached by Owen who asked for help in proving his father's innocence. Owen wanted to use a clandestine Animus owned and modified by the mysterious Monroe to relive his father's memories of the bank robbery. Although Monroe revealed that he could not help Owen due to the limitations of the Animus, Javier's curiosity led them into using it anyway. Together the pair subsequently experienced the genetic memories of their respective ancestors, who met during the Spanish conquest of the Aztec Empire.
During the session, Javier felt the power of one of the Pieces of Eden firsthand when Hernán Cortés used it on his ancestor Chimalpopoca. The discovery of clues potentially leading to the Trident of Eden also attracted the attention of both the Assassin Brotherhood and the Templar Order.
Personality and characteristics
During his Animus session, Javier was confused by the feelings of his heterosexual ancestors, notably the physical attraction Chimalpopoca felt for Cortés' lover, the beautiful Marina.
Javier possessed a reckless streak, as evidenced when he broke into the police warehouse for Owen's father's casefile.
Equipment and skills
Thanks to the Bleeding Effect, Javier had gained his ancestor Cudgel Cormac's skills, which served him well during the search for the Trident of Eden. Additionally, he had learned basic combat and freerunning from Griffin.
