Theresa Chasar (Doom 3)

Theresa Chasar was one of the few female UAC employees in Doom 3. She is named after the sister of Tim Willits, the co-owner of id Software. According to her PDA, she has done a research with other UAC scientists on the Plasma gun. Right after the demonic invasion began, the Marine approaches to her, and her head and spinal cord rips out, forming a Lost Soul.
