Pepita is a dog given to Markus and Valerie as a gift from the President of Culuruma. During the exploration of a Culurium mine, she was shot with a shotgun while protecting Dr. Vaughn and Dr. Blaylock. This led to an operation that required either Dr. Blaylock or Dr. Vaughn to remove the shotgun pellets, suture the wounds and recover Pepita's pulse with the defibrillator several times. Pepita later recovers and with her help, the military was able to track down Ramirez, Leland, and Kidman.
