Set across three distinct eras—Viking-era Scandinavia, feudal Japan, and World War II in the skies—the film follows three legendary warriors: Viking Queen Ursa on a brutal vengeance quest alongside her son; samurai brothers Kenji and Kiyoshi torn by honor and betrayal; and U.S. Navy pilot Johnny Torres dogfighting in a Predator-infested Atlantic. Each vignette pits human skill and courage against the alien hunters, culminating in a thrilling convergence on the Predator homeworld, where the trio must unite to survive a gladiatorial showdown. With razor-sharp painterly animation, inventive Predator tech, and a sweeping score, Killer of Killers deepens Predator lore while delivering visceral, globe-spanning sci-fi action.
