The Tyrant-Virus variant: T-R. Through strenuous research into the Tyrant (T) Virus, we here at the PA branch have finally collected enough data to give a clear report regarding the surprising mutations found in certain individuals afflicted with the mutagen. Similarly, we discovered that Tyrant models who suffered similar near-fatal injuries were the only models to undergo a transformation into an enhanced form. Attempts to manually cause Tyrants to mutate further resulted in the death of 4 T-103s and a T-105. R. Berger, Head Researcher Umbrella PA
