San Diego Comic-Con is populated almost entirely with epic fictional heroes caught in the eternal fight between good and evil. But for one brief, hilarious hour Friday afternoon, six of them lightened the mood on EW’s annual Brave Warriors panel, for which Game of Thrones’ John Bradley, Krypton’s Cameron Cuffe, Evil’s Michael Emerson, Project Blue Book’s Aidan Gillen, Black Lightning’s Cress Williams, and Cobra Kai’s William Zabka all joined EW editor-at-large Lynette Rice for a lively conversation about their many on- and off-screen battles, big and small.
