Trog

Trogs are creatures in the Pitt, appearing in the Fallout 3 add-on the Pitt and $$

Background
 According to Sandra Kundanika, Troglodyte Degeneration Contagion or TDC causes humans to transform into trogs. The disease is the result of intensively concentrated ambient radiation exposure combined with the unique industrial toxins and pollutants in the region. It is not contracted via contact with the infected. Approximately 20% of the populace have transformed into trogs, attacking anything on sight. Children born in the Pitt have a 100% degeneration rate and become feral within weeks of birth. Trogs kill former friends and loved ones. They say lines like "Kill it!", "Meat!", "Hungry!", and "Food!" when attacking, and "Hurts!", "Pain!", and "Why?" upon being injured. They mutter "...peace..." or "Thank you..." before they die. 

Appearances
Trogs appear in Fallout 3 and Fallout 76.
