Alexia Ashford is one of the main enemies in Resident Evil: Code Veronica. She reappears in Resident Evil: Code Veronica X and Resident Evil: The Darkside Chronicles.
Alexia Ashford was artificially created along with her brother Alfred Ashford. Alexander Ashford used the DNA from one of his family's ancient matriarchs, Veronica Ashford. By combining the DNA with an intelligence-raising gene along with a surrogates egg, he managed to create twins. Alfred was born with a slightly high intelligence while Alexia was born with a phenomenally high one. Because of her high intelligence she was often shunned among her peers and was often alone with only her brother by her side. She soon became egotistical, thinking she was special and superior to all others. Alexia graduated from a University at the age of 10 and was named the youngest chief senior researcher of the Umbrella Corporation.
In 1983, around her 12th birthday, Alfred informs her that there is a secret door located in the Antarctic Umbrella Facility. Needing her family gemstone to open it, the two journey inside the room and discovers the truth behind their creation. After discovering the news the two become very hateful towards their father. Alexia then uses her dad as one of her test subjects for her T-Veronica Virus. After being infected their father turns into a horrible monster known as Nosferatu.
Taking note on her father's progress, she uses the data to improve her virus. Wanting to use the virus on herself in order to become a superior being, Alexia injects herself with the T-Veronica Virus. She is put in a cryogenic suspension for fifteen years to allow the virus to slowly mutate. By doing this, the virus will not mutate at a face pace, destroying her tissues as it did her father. This way she would be in full control and could mutate at her own will. In 1983, Alexia assigns her brother with task of protecting her and carrying out her objectives while she proceeded to enter a cryostatic state.
Resident Evil: Code Veronica
After fifteen years, she is awakened to see the death of her brother Alfred Ashford. Enraged by the death of her brother, she used her new powers to control a tentacle lying under the Antarctic base, to destroy the escape vehicle of Claire Redfield and Steve Burnside. Alexia then captures the two with the intention of using them as test subjects in her experiments and to make them pay for killing her brother.
She imprisoned Steve and infected him with her strain of the T-Veronica Virus. Later on she confronts Albert Wesker, who is on a mission to retrieve a sample of the T-Veronica Virus. After realizing that Alexia was impervious to all his physical blows, Wesker leaves it up to Chris to defeat her. Chris Redfield does manage to defeat her, however Alexia returns once again now looking like a giant flower. Once again Alexia is defeated but she manages to mutate once again, into what looked to be some type of dragonfly form. During her third state of mutation Alexia is able to absorb all gunfire. Chris must use an experimental weapon called the Linear Launcher to defeat her.
