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 to give him a shipment of cattle prods for using them to control the nightstalkers that starting to become aggressive. At a time, he comes front to the nightstalker's reserve with a cattle prod, but when he opened the door, he was directly killed by them. It's probably this event which allowed the nightstalkers to escape in the wild and which caused the death of most of the scientists in Big MT with the escape of cazadores.

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
