What is the name of the virus created by Alexia Ashford in Resident Evil Code: Veronica?

Alexia Ashford created the T-Veronica virus in Resident Evil Code: Veronica.

The virus is named after Veronica Ashford, the ancestor whose genetic legacy is central to the Ashford family’s history. Alexia studied the ancient queen-ant relationship and used the virus in experiments intended to produce enhanced biological abilities and long-term control over the infected host.

Alexia injects herself with the virus and enters cryogenic suspension for fifteen years so that it can adapt within her body. When she awakens, she possesses extraordinary physical abilities and becomes the game’s principal biological threat.

T-Veronica is distinct from the T-virus, the outbreak agent associated with the original mansion incident, and from later agents such as the T-Abyss virus in Resident Evil: Revelations. The similar naming of Resident Evil’s viruses makes their separate origins a frequent source of confusion.
