Umbrella's attempts to develop a B.O.W. emphasizing combat ability gave birth to this, and it exhibited a certain measure of completion. The development staff were evidently proud of their creation, naming it after the very mutagen used to create it - "Tyrant". Exceptional physical capabilities and the intelligence to obey and execute orders were realized upon its design. It was due to be commercialized after completing the final "test" of the combat model against veteran soldiers.
