The Cerberus (Code Number: MA-39) was dog-based B.O.W. (Bio Organic Weapon) series developed by the Umbrella Corporation using the t-virus. By applying the social nature of dogs, tactical use was possible and the Cerberus entered the most successful category in test subjects using animals as hosts. It is distinct from the Zombie Dog, but their characteristics are the same. 1 2 3 4 5 6 7

The Cerberus series was created with the t-virus βI strain in the second stage of the t-Virus Project at the Arklay Laboratory. Military-trained Doberman pinschers were chosen as hosts since their prior training made them easier to control. Following infection they displayed resounding capabilities in combat, were capable of following commands and displayed a higher resistance to the necrotic effects of the virus than humans. These attributes made it one of the company's most successful B.O.W.'s.

Although clone production was conducted using the code number MA-39 for the Doberman pinscher breed, variations using other dog breeds were also planned and deployment of the Cerberus series together in various intended uses were considered. By May 1998, a test on practical use as a pack was carried out in the courtyard of the Spencer Mansion. However, as a result of the virus leak accident on May 11, many subjects escaped from the facility and became wild in the surrounding forest. 8

Among the bizarre murder cases which occurred in the outskirts of Raccoon City, roughly more than half of the cases were committed by the escaped Cerberus subjects. Prior to the accident, the research team had planned to experimentally administer the t-virus to other dog breeds such as the Saint Bernard. However, these experiments were halted due to the accident and the Doberman pinscher breed has become synonymous with the Cerberus.

The Doberman-based Cerberus was used in a bioterror attack against the Mediterranean island headquarters of TRICELL Inc. by a rival company. It was also used by bioterrorist Glenn Arias in New York City.


The Cerberus' features were at a degree similar to rather large dogs, but its muscular strength, durability, jumping range, agility, speed and combative instincts were strengthened by the virus. Like most infected mammals, decomposition of the outer skin and flesh was extreme, even exposing the ribs. In addition, because the virus' necrotic effect on the brain removed any sense of fear, its tolerance for pain and especially gunshots was higher than common military dogs and it would attack relentlessly and ferociously until it killed its target.

The greatest feature of the Cerberus was its ability to harness coordinated activity with others. Under the direction of a trainer, it could be made to act on several commands at once. Its primary attack pattern would be running around a target to disrupt and disorientate them, then pounce with their entire body weight and push down the weakened opponent to tear at its throat. When more than one Cerberus dealt with a single target, they cooperated and attacked sequentially in waves without providing the target an opportunity to rest.

Some developed severe ocular degeneration and in many cases were nearly blind as the eyeballs putrefied. However its keen sense of smell and acute hearing remained. In combat situations, if the objective was to clear a small area, the Cerberus was considered a successful cheap product sufficiently meeting the requirements of a B.O.W. However, without prior training its excessive aggressiveness posed a problem as it was otherwise very difficult to control. As its heightened metabolism made it constantly hungry, the resulting impulse made it nearly impossible to secure. This problem was observed in the Zombie Dog but was prevented by using only dogs with military training prior to infection.

(As only the "Cerberus" model based on the Doberman pinscher has been documented, the above may not precisely relate to other breeds)


According to Greek mythology, Cerberus (or Kerberos) was a monstrous three-headed hound which resided on the far side of the river Acheron and was employed by Hades, the god of the underworld, to guard the entrance to the portal of death. This “demon of the pit” allowed the restless spirits of the dead to enter, but never leave. "Omnes relinquite spes, o vos intrantes." ("Abandon all hope ye who enter here.")
