Dr. Calis

Doctor Calis was the chief scientist in the X-13 research facility in the Big Mountain Research and Development Center.

Background
Dr. Calis was the chief scientist in charge of the X-13 research facility under the command of Dr. 0 in the Big Mountain Research and Development Center. All that is known about him can be found on the terminals in said facility.

He asked Captain Hamm, Big Mountain's security chief, to provide a shipment of cattle prods in order to control the nightstalkers, who were becoming increasingly aggressive. Eventually, he evidently decided to face the nightstalkers directly, an error in judgement that cost him his life. His skeleton, still clad in a lab uniform, can be found sprawled on the ground outside the nightstalkers den. It is also possible that this event allowed the nightstalkers to escape into the wild, leading to the further death of most of the scientists in Big MT with the escape of cazadores.

Dr. Calis was survived by evidently no one, and recalled with scorn by his colleagues, whose negative comments can be found on terminals scattered around the facility.

When asked why he created the nightstalkers, Dr. Borous states that Calis dared him to splice together mountain lions, eagles, and condors, which somehow lead to a combination of coyotes and rattlesnakes.

Appearances
Calis is mentioned in numerous terminals in the X-13 research facility and also appears as a skeleton in the Fallout: New Vegas add-on Old World Blues. He can be found outside of the entrance to the former nightstalker's reserve.
