The latest episode of Lanterns finally teased a season-spanning threat that had been alluded to in the HBO show’s trailers: The Manhunters. Having appeared in Green Lantern comics since the 1970s, these shapeshifters are the precursors to the Green Lantern Corps, but were replaced after they rebelled against the Guardians of the Universe. With overarching themes of replacement and succession permeating Lanterns, the Manhunters are a genius fit for an antagonist.
