Entertainment Weekly reports that actor Justice Leak has been cast as the villainous Hellgrammite in CBS's Supergirl. Leak is no stranger to comic book adaptations, having previously appeared in both The Walking Dead and Powers.
In comic books, Hellgrammite is actually entomologist Roderick Rose, a mutated villain with insect-like powers. The report doesn't state how closely the TV version will connect to his comic book origin.
Supergirl premieres October 26 on CBS.
