[Name] T-Veronica Virus [Source] Resident Evil Code: Veronica [Symptoms] 
A powerful strain of the Progenitor Virus, created by combining it with a rare retrovirus found in the genetic make-up of ant queens, discovered by unstable scientific genius Alexia Ashford, the result of an advanced cloning experiment. It is encountered in Code: Veronica, when it is being used by Alexia Ashford in her attempt to take control of the world. She experiments on her father, then on herself; her father is transformed into a terrifying monster, while she, going into hibernation after giving herself a dose of the Virus, manages to gain control over it and retain her personality and intelligence. She eventually becomes a dragonfly-like creature who has to be killed by Chris Redfield. It appears again in the 'Operation Javier' section of Darkside Chronicles, where it is being used by Javier Hidalgo to cure his daughter Manuela of an inherited illness. He also tried to cure his wife, but the virus overwhelmed her and turned her into a mutant. Manuela uses her developing powers (similar to Alexia Ashford's abilities before transforming into her insect form) to defeat the mutated Javier, and is then evacuated by Leon Kennedy and Jack Krauser. If Manuela survives at the end of the game, it is said that she is cared for by the US government, but her ultimate fate is left unknown.
