Eliminator

The Eliminator is a primate-based B.O.W. and one of several early prototype weapons developed exclusively by Dr. James Marcus during the test phases of the t-virus' capabilities as a weapon, but before the selection of a specific host for the strain. Developed alongside the Eliminator were the Lurker and Plague Crawlers, further displaying Marcus' fascination with the use of unlikely subjects as deadly weapons.

Primates infected with the virus exhibited rapid development of excess muscle tissue, resulting in visible tearing to the subject's skin. Further exposure caused a rapid increase in strength, agility, stamina and aggression, resulting in a deadly and efficient killer.

Although initially deemed a successful product, the Eliminator was found to have undergone significant decline in overall intelligence as a result of t-virus administration, which was supposed to be its greatest asset to Umbrella's B.O.W. program. Mass-production of the Eliminator was canceled and only a handful of specimens preserved for further testing and general research. Dr. Marcus instead turned his attention to the potential that human subjects presented as virus hosts, later unwittingly providing William Birkin and Albert Wesker with the first scraps of information pertaining to the creation of the Tyrant-class B.O.W. The existing Eliminators were left to rot, although James Marcus released them on Rebecca Chambers and Billy Coen after they had infiltrated the Umbrella Management Training Facility. Marcus noted that the remaining Eliminators had been exhausted by negligence and hunger, suggesting they had not been at full strength when encountered. Some of these B.O.W.s were mass produced in the Russian Umbrella Facility and were released in 2003 by Sergei during the outbreak in order to eliminate the anti-umbrella forces led by Chris Redfield and Jill Valentine from proceeding any deeper to the facility.
