User:NytewolfAU2k7/Genotoxic Parasite

The Genotoxic Parasite is a creature that forever wanders in search of a host body to grow. It usually prefers mutants, as they generally are a lot slower than a runner, but it will attempt to attack a runner who crosses it's path however.

For genotoxic creatures of any type, it is best to stay out of melee range by circling them, rather than standing still.
