The Faceless Hunter to the Silver Surfer, with a twist. Like the Surfer, he is the herald of an oncoming scourge of entire worlds, a deal he made with said scourge - Starro in this case - over the fate of his own planet. The twist being he's everything the Surfer isn't. Norrin Radd became the Surfer in exchange for Galactus sparing his world. In this case, though, we find out in the final battle that when Starro found a faceless race that his facehugging mini-Starros could not control, he was just going to leave, but the man who would become the Faceless Hunter said that he would find other worlds for Starro to enslave in exchange for Starro destroying his world. He proves to be an Omnicidal Maniac and eclipses Starro as the final enemy of the season finale.
