NE-T virus

The NE-T virus is very similar to the T-virus, but was designed specifically for the Tyrant Project.

According to the series timeline, Umbrella required BOWs that were not only stronger, but could understand and complete missions, and due to the nature of the T-virus, all of its BOWs were unable to do this. The project was divided between an American team, led by Birkin, which would work on increasing the BOWs' strength and ability to detect organisms, and a European team that would work on increasing their intelligence. The two teams traded theories and ideas that included the first experiments in directly operating on a subject's brain. The American team succeeded in creating the NE-T virus, along with the T-002, which could follow simple orders such as "Restrain" and "Attack", though its intelligence was insufficient for field operations.

In response to reports of the T-002’s failure, Umbrella renamed the European team's project with the title "Goddess of Vengeance", or "Nemesis", and gave it the new goal of eliminating all anti-Umbrella elements; specifically, the STARS. The European team made a breakthrough with the creation of the NE-α, an organism created from the NE-T virus that affected the host's brain. Further experiments with this strain led to the creation of the T-103, also known as "Mr. X".
