Dr. Warren was an ambitious yet psychotic scientist who was so obsessed with science that he would do anything to make it work; so much so that he ultimately showed no remorse for his devastating actions whatsoever in contrast to his assistant Dr. Clive
Seeing all the chaos and destruction the violent riots had produced around London, Dr. Warren decided to make a violence-inhibiting genome which would make people calmer. Dr. Warren mixed around with different formula and strands and eventually found the Ebola virus which he then mixed with his inhibitor. Unfortunately the virus mutated, and produced a new virus, which made people extremely angry and aggressive. Dr. Warren tested it on a violent criminal whom he had got from a police cell, but it made the man even more violent and so Dr. Warren shot the criminal to death; Dr. Clive was horrified by this whereas Dr. Warren was merely disappointed
It was revealed the doctors were hired by the Financiers, a group of wealthy businessmen who had hired the pair to create a cure for all homicidal rage. Dr. Warren was talking business-like on the phone to one of the businessmen where Dr. Warren said Dr. Clive had killed himself due to the creation and he was disappointed in the results. The Financier said perhaps it was for the best, but then Dr. Warren heard scratching at his laboratory door and went out to check. Suddenly he was ambushed by a rabid monkey which ended up vomiting Infected blood in his face, thus infecting Dr. Warren as a result. Dr. Warren screamed and then became an Infected just moments later. Dr. Warren now screamed in rage and went round killing people, Infected by his own creation. He then died of starvation in two months
