Josh first appears in "Required Reading" at the night club Sinema, then on the high school's lacrosse field. As an electric eel Chimera, Josh was responsible for the electricity outages at the school, then at the hospital feeding on the electrical wires with his fangs. Josh, in a feral state, attacks Stiles on the hospital roof, but Theo engages him. Theo manages to overpower Josh, and tears out Josh's throat, killing him. In "Status Asthmaticus", Josh is revived by Theo via a restorative serum courtesy of the Dread Doctors. Theo declares to Josh, as well as Hayden, Corey and Tracy Stewart that Theo is their Alpha, and they all belong to him. Along with the others, Josh follows Theo.
