1st Appearances of Voxx and Optic.
*Titan tears himself away from Golden City to take a bite out of Cinnabar Flats! Grace tries to enlist the help of the alien from the Vortex even as Titan shows up like an angry earthquake, bent on pounding the base to rubble. Division 13, King Tiger, and Hero Zero all want in on the action, but the real threat may come from the underground cells of Block 13, where sedated inmates, mutated by the Vortex years ago, are freed by Titan's attack! The last three issues of this megaseries will draw your attention because Legend creator Mike Mignola draws the covers! *Source: darkhorse.com
