Cerberus

The MA-39 Cerberus was a B.O.W. series developed in Umbrella Pharmaceutical, Inc. labs, such as the Arklay Research Facility, from a doberman pinschers infected with the tyrant virus.

Information
Although suffering from a similar necrosis to humans infected by the t-virus, Cerberi retain much of their former agility, with a noticeable increase in durability and aggression. In most cases, potential prey should listen for the sound of padding paws as a clue to their presence, with a growling warning that a Cerberus has become aware of the player and is preparing to attack. They will let out a pained yelp when killed.

Following the deliberate outbreak of t-virus caused by Dr. James Marcus, a pack of Cerberi escaped into the Raccoon Forest surrounding the facility, attacking and feeding on hikers and anyone else wandering too deep into the woods. It was these attacks (as well as those committed by at least one band of roaming zombies) which eventually led to the formal investigation of the area by the police department's Special Tactics And Rescue Service in July 1998.

Trivia

 * This creature was named after Cerberus, the mythological guardian of the Greek underworld, a gigantic dog with three heads and a collar made of poisonous snakes.
 * Only four Cerberi appear in Resident Evil Zero
 * In Resident Evil: Afterlife, two Cerberi encircle Albert Wesker and seem to be protecting him from Alice. Wesker also shows the ability to command the Ceberi by telling them to "stay" and "sit". This shows that Albert Wesker has taken control of some of the B.O.W's.
