Pedro Fernandez was a TerraSave member and co-worker of Claire Redfield. Athletic and being a trained mechanical engineer, Pedro was involved with TerraSave even in his student years. He has a bright personality but becomes upset easily in a crisis. [excerpt 1]
In 2011, Pedro was a guest at a party at TerraSave headquarters that was attacked. He, alongside other TerraSave members, was abducted and taken to Sushestvovanie Island. He awakened in a forest alongside Gabriel Chavez, Edward Thompson and Neil Fisher, with strange bracelets on their arms. Through these they were contacted by a woman calling herself the Overseer who insisted they head for the Wossek. They were then attacked and pursued by several Afflicted, former residents of the island driven insane through torture and abuse, who end up killing Edward. Thinking quickly, they cut off his hand to investigate the bracelets. He and Gabriel are separated from Neil during the pursuit before they arrived at the Wossek, a pub in a Fishing village. Here they meet up with Claire and Moira Burton who were also instructed by the Overseer to head there. Soon they're once again contacted by the Overseer, who informs them about a special virus with which they were injected, one that reacted solely to fear. Throughout this, he studied the bracelet they pried from Edward's body, leaving several notes strewn throughout their path.
He then found a Drill that he used to help Claire obtain fuel for a helicopter that Gabriel was fixing. However, soon after the siren in the bar was activated calling the Afflicted, causing them to attack the bar. Through this he became more and more agitated and scared, until he mutated. Pedro in his mutated form attacked Claire and Moira with his drill and attempted to kill both of them. When they were unable to stop him, Neil appeared and ushered them to safety.
Six months later, Barry Burton and Natalia Korda encounter a further mutated Pedro in the apartments near a crashed helicopter with Gabriel's corpse. Pedro constantly apologized to his lost friends while in this state. Seeing Barry and Natalia, he attacked them with his drill until Barry managed to kill him and take his drill.
After succumbing to the virus, Pedro mutates into an Afflicted, although his transformation is a unique mutation. He stands a head taller than the player characters and his joints, most notably his right arm swells up, allowing him to wield the drill more effectively. His most notable feature are the numerous eyes that erupt from his body. It is unknown what purpose these eyes have but destroying them all will instantly defeat him.
