Following FX's announcement last week that The Strain will debut on Sunday, July 13, the network has released five new trailers for this upcoming series, based on the novel trilogy by Guillermo del Toro and Chuck Hogan. While we don't get any footage featuring the main cast members such as Corey Stoll and Mía Maestro, these brief teasers showcase some of the creepy parasitic creatures that will be shown in this series, along with a simple warning: "He is here." Take a look at these trailers, and stay tuned for more footage and photos as we get closer to the mid-July premiere of the Pilot episode.
