Walter Skinner - Vietnam vet and defender of Scully and Mulder

Walter Sergei Skinner is an Assistant Director of the X Files. Initially as unfriendly towards Mulder as the rest of the FBI, Skinner has gradually grown to respect Mulder and Scully's work on the X Files.

He's defended the Agents staunchly, going out on a limb several times to protect them. His faith in Mulder springs from a paranormal experience Skinner underwent in Vietnam. With Mulder's disappearance, Skinner becomes more involved in the X Files, and in helping Scully find Mulder.
