- The Reverse Evolution virus is a malicious self-replicating computer program from the Micromaster Collection portion of the Generation One continuity family.
The Reverse Evolution virus, developed by the Decepticons, was capable of turning Autobots into Decepticons. Victims of the program turned black, with white Decepticon symbols, and showed destructive tendencies.
All of the virus's known victims were originally Seiberdroids who were "evolved" into Autobots or Decepticons by a dimensional shockwave. The virus's name suggests that the change from Autobot to Decepticon was somehow based around this effect, rather than involving a shell program.
Micromaster Collection story
Decepticons developed the virus, then captured Road Police and infected him with it. He proceeded to spread it to Circuit, Glide, Neo-Wheel, and Discharge. Joe and Sireen developed an antivirus program to return the other Turbo Team members to normal. In order to get the program into their systems, Sireen surrendered to the others and convinced them to combine into Sixturbo, activating the program just as they combined. Sireen was briefly turned into a Decepticon himself just before the antivirus program took effect, turning all six components back into Autobots.
The antivirus program was the basis for the Vaccine Program Gun.
