[[File:Wesker virus.png|thumb|Wesker injecting himself with the virus.] The Prototype Virus was an experimental strain of the Progenitor Virus used by Albert Wesker to enhance his body as well as fake his death.
Effects
This virus increases the metabolism of its host, giving them incredible superhuman strength, speed, agility, endurance, and healing factor. The only known host of the virus is Albert Wesker, so most knowledge of its effects comes from observations of him.
The virus' effects limits itself to muscle tissue and the lower organs, leaving the brain relatively intact. This breakthrough means that the subject's mind is retained and no ill effects take place.
The virus has a unique effect on ocular tissue. The only visible effect of the virus is the way in which it affects the subject's eyes.[1] Wesker demonstrates the ability to move faster than the human eye can see, at least in short bursts. The only way to move accurately at such extreme speeds would be by viewing the world in hundreds of frames per second, most likely in the same range as birds. However, he is also capable of interaction with the world with the 'normal' speed of a human, viewing the world in the tens of frames per second. This would indicate that the subject has voluntary control over visual perception, or else his eyes automatically adjust to the speed at which he is moving.
The virus is very unstable, so the host has to use a special serum to keep it under control. The serum itself must be given in very precise dosages, lest it act like more of a poison and damage the host from the inside.
Origin
The strain was developed by for use in the "Wesker Project" advanced by Ozwell E. Spencer as part of a special screening process for identifying the most genetically gifted of the Wesker children. Only two of the thirteen remaining test subjects survived: Albert and Alex Wesker.
