In the new Netflix show "Parasyte: The Grey," a race of slug-like parasitic creatures have arrived on Earth. They've worked their way into unsuspecting humans, using them as hosts and transforming their bodies in grotesque ways. This Korean horror series isn't one for the faint of heart.
It's based on the original Japanese manga "Parasyte" from Hitoshi Iwaaki, which debuted in 1989 and has become one of the best-selling manga series of all time. It's since spawned two live-action movies and a TV series, "Parasyte -the maxim-," that aired in the West during Adult Swim's Toonami block in 2015.
