(Capcom's primary storyline)
The Veronica Plant was a plant-based B.O.W. created through the use of the T-Veronica virus.
This plant was first cultivated in the Umbrella Antarctic Base by Alexia Ashford. After the experiment she had done to herself, Alexia is capable of using the plant's tentacles to do her will, and even mutating her body into an insectoid monster.
Javier Hidalgo secretly cultivated the Veronica Plant in his mansion's greenhouse. It is considered to be one of the strongest and most dangerous B.O.W.s in existence, due to its spores being able to transform neighboring vegetation into Veronica Plants. If allowed to reproduce, it could destroy the ecological system of an entire continent with horrifying speed and no hope of containment; for comparison, it was estimated that approximately 60% of the Amazon would be infected within 48 hours of its initial spore dispersion.
In 2002, during the events of Operation Javier, Leon S. Kennedy and Jack Krauser were sent to apprehend Javier because of his dealings with an Umbrella researcher rumored to be hiding in South America. In a final attempt to kill the incoming agents, Javier fused with the blooming Veronica Plant to become the V-Complex.
