The Parasite (パラサイト?) is an armored insectoid species from Street Fighter 2010. Parasites are aggressive and have a carapace harder than ceramic. They can assimilate a host to control it, also greatly increasing its power. In order to stop those powerful parasites, the Galaxy Police sends the cyborg Kevin Straker to destroy them.
In the English version, Parasites were changed into Cyboplasm, a substance discovered by 'Ken' and Troy. When properly administered, Cyboplasm could make a person several times stronger than normal, helping to keep people alive in other planets. But in large doses, it comes alive and takes over the body and mind of its host, turning them into violent, mindless super beings. One day, Troy was killed and the Cyboplasm formula was stolen, being misused and spreading chaos in several planets.
