The T-103 model can be programmed to achieve specific goals, such as the acquisition of the G-virus sample contained within Sherry Birkin's locket. However, 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.
