(DeCandido's novelizations of the Anderson films)
Aaron Vricella was the leader of a small group of anti-Umbrella eco-terrorists, whose mission was to bring the company down from the inside using spies.
To this end, he recruited Matt Addison. Addison, however, felt that his sister Lisa would be a better choice, and Vricella agreed despite his misgivings. Although both of the Addison siblings died as a result of the venture, Vricella's fate remains unknown.
