Nothing is known about Galvan's life prior to or as the outbreak began, except that he was part of the Mexican Navy.
Sometime after The Abigail hits shallow waters off the coast of Rosarito in Baja California, several people make their way on board, including three socialites and three officers from the Mexico Navy, including Galvan and Tintos. Victor eventually finds his moored yacht and climbs on board to find everyone undead. He retrieves a harpoon gun and shoots a zombified woman with it, impaling her to the wall before he is attacked by Tintos. After Victor slams the undead Tintos against a table and stabs him in the head, he proceeds with putting down Galvan, who falls down a flight of stairs, and the remaining zombies.
