Tyrant T-103

The T-103, was the first mass-produced Tyrant-type B.O.W ., finally reaching Umbrella's goal of fully-functioning bio-weapons capable of operating within mission parameters.

The creation of the T-103 lies in the T-002, which was destroyed by S.T.A.R.S. Alpha team in July 1998. The data acquired by Umbrella on Alpha team's reports proved that Tyrants of similar design could be used as adequate bio-weapons. With this data the T-103 was born.

Mass-produced Sheena Island's aptly named 'Tyrant Plant', the high incompatibility ratio was solved by injecting subjects with the hormone Beta Hetero Nonserotonin''. This substance is an adrenal based'' neurotransmitter extracted from the Locus Ceruleus. A vast supply was found in male adolescents. They must not be anesthetized in order to ensure maximum amounts of the substance are extracted. Production was carried out on Sheena Island until it blew up.

During the Raccoon City outbreak, a T-103 was dispatched to retrieve one of the last of the remaining G-virus samples; five others being transported by the same helicopter were used to stop a U.S. Special Forces incursion in the north of the city. This model does not feature claws or the exposed heart seen in the previous models.

It is no longer sentient, meaning it has no true understanding of the purpose of its mission. This can cause it to perform ill-advised actions in some cases, such as diving into the smelting pit in William Birkin's laboratory. Unlike its predecessors, the T-103 is known for its near-human appearance, mysterious silence and trench coat. Also, it exhibits no visible mutations like the huge talons prominently featured on earlier models. This changes, however, if T-103 suffers serious injury, after which it will mutate and display the features seen in other Tyrant models. This mutation includes talons on both hands and increased muscle mass. T-103 could also be programmed to achieve specific goals, such as the acquisition of the G-virus sample contained within Sherry Birkin's locket
