The Cerberus (ケルベロス keruberosu?) (development code: "MA-39") was an early attempt at creating a controllable Bio Organic Weapon by Umbrella USA, in a project led by the Arklay Laboratory. They should not be confused with "zombie dogs", which encompasses all dog breeds infected with any t-Virus strain in the secondary form. Pronounced as the Greek word, "Kerberos", this creature was named after the mythological guardian of Hades, a gigantic dog with three heads and a collar made of venomous snakes.


The Cerberus Project began in the early 1980s as the β strain was developed. It was hoped that the improved t-Virus strain would create mutants more adequate for sale as military products, and dobermans were specifically selected for the project due to their traits favouring military service. Though they suffered skin deterioration, their muscles were left largely intact, and this and their increased strength and aggression made them more dangerous. As this B.O.W. species was created from an existing animal, unlike the Hunter Program, the cost to create the Cerberus prototypes was low.[2] Deemed a success, the later Cerberuses were created by cloning one of the prototypes.[3][excerpt 1] The Arklay Laboratory conducted testing on these dogs in the courtyard until the t-Virus outbreak in 1998 when they escaped.[3] Hungry and lacking their Umbrella trainers, they turned feral and began killing and eating hikers out in the Arklay Mountains. Members of this pack fought with S.T.A.R.S., but it is unknown how many escaped the Mansion Incident.



  1. Excerpt from Inside of BIO-HAZARD, p.41: "クレイウィルスβ I型によって犬のDNAを書き換えて作られたBOW。 外見上は、 やや大きな犬といった程度でさして特徴もないが、 ウィルスによって筋力や闘争本能が飛躍的に強化されている。 また恐怖感も持たないので、 通常の軍用犬以上に銃声や痛みに対しての耐性が高く、 相手を仕留めるまで獰猛に襲いかかる。 このケルベロスは、 犬本来の持つ社会性を応用することにより戦術的な運用も可能で、 動物を宿主とした実験体のなかでは、 最も成功した部類に入る。 もともと軍用犬としての能力が高いドーベルマンを素体としたタイプがMa-39としてクローン生産されたが、 ほかの犬種を使ってのバリエーションも予定されており、 さまざまな用途に合わせたケルベロスシリーズの展開が考えられていた。 施設の中庭で集団運用のテストが行われていたが、 事故後施設より逃走し、 近隣の森で野性化していた。"
