t-Phobos Virus

The t-Phobos virus was a variant of the t-virus developed by the research team of Alex Wesker on Sushestvovanje Island. Its most notable characteristic was that it reacted to fear, particularly adrenaline and noradrenaline.

The t-Phobos prototype was discovered by one of Wesker's researchers as a mutant strain of the t-virus that reacted to noradrenaline, secreted when a person feels fear. 1 The discoverer wrote a report on the virus and presented it to Wesker. While the other researchers deemed it useless, after taking a look at the report Wesker was deeply intrigued by its characteristics. She selected the discoverer as research leader to commence development and used mine workers as test subjects. 2 3

On November 8, 2009, eleven human candidates were fitted with special bracelet-type sensors to monitor the host's adrenaline and noradrenaline. They were intermittently subjected to strong mental load, three died immediately while the remaining eight were shot to death for symptom onset and disposed of. 4

On January 24, 2010, the trial strain of t-Phobos was one more step to completion as previous improvements restrained the original t-virus' lethality and a mechanism to develop symptoms under intensive psychological burden was achieved. The additional target value of a minus two percent antibody rate was also accomplished. 5

On February 5, 2010, t-Phobos trials were conducted and ended three days later with thirty dead test subjects. Test subjects were disposed of in the island's mine. 6 As the virus neared completion, Wesker promoted the discoverer as laboratory director. After research and development on t-Phobos was completed, Wesker's research team focused attention on the Uroboros virus. 7

In 2011, the virus leaked from the laboratory and contaminated the island, causing its residents to become Afflicted through secondary infection. 8 t-Phobos was injected into Natalia Korda and several abducted members of TerraSave to determine the best "vessel" for Wesker's rebirth ceremony. Korda adapted to the virus due to her lacking emotional response to fear and she was taken for the ceremony. Moira Burton also conquered fear and adapted to the virus.


t-Phobos possessed capabilities similar to the t-virus but reacted solely to adrenaline and noradrenaline, hormones secreted in large amounts in times of stress such as anxiety and fear. Once in the bloodstream the hormones interacted with the virus causing it to spread at speeds dependent on the amount secreted and how long those levels remained high. Compared to other virus strains which relied on a host's physical condition, t-Phobos relied on the host's psychological condition.

The sensor bracelets to measure the amount of adrenaline and noradrenaline were color-coded to designate particular stages. Green was normal, orange was stress, flashing red was fear and red was pathogenesis, the onset of symptoms. Although red typically signified an impending mutation, adapted hosts could show permanently red with no apparent symptoms due to the virus' adaptation to the host. 9

In the case of hosts with higher than average amounts of adrenaline and noradrenaline beneath the threshold for transformation, the virus slowly altered the host's genes causing superhuman strength, regenerative ability and glowing red eyes similar to Progenitor virus adapters. However, these effects would only manifest upon death or severe injury.

The effects of secondary infection on a human host were similar to the t-virus, but the entire infection and mutation process was dramatically slowed due to its regulation by adrenaline and noradrenaline. In the Afflicted stage, hosts remained human but were slowly eroded by the virus and plagued by madness. In the Rotten stage, the virus infected every cell in the host's body and transformed it into a creature identical to a Zombie. The characteristics of this mutation were the same as the t-virus.


The virus is named after "Phobos", the personification of fear in Greek mythology. The word itself also means fear.
