The first 10-episode season of Primal was split into two 5-episode parts. The series has no dialogue throughout its first season, before incorporating minimal dialogue in the second season, in line with Tartakovsky's previous work. The first 2 seasons revolve around the journey of Spear (Aaron LaPlante), a Neanderthal, and Fang, an uniquely intelligent female Tyrannosaurus rex, both of whom lose their families early-on and decide to join forces to survive their unforgiving environment together, eventually discovering developed civilizations that they end up in conflict with. Primal is set in an anachronistic vision of prehistory, portraying extinct dinosaurs, Ice Age mammals, and early hominids all coexisting with post-metallurgy Homo sapiens in a single time period, incorporating many elements of science fiction, fantasy, horror, action, and adventure. It is the first combined action/sci-fi/horror animated series from Cartoon Network Studios and Williams Street. Primal (also known as Genndy Tartakovsky's Primal) is an American adult animated action horror television series created and directed by Genndy Tartakovsky for Cartoon Network's night-time programming block, Adult Swim.
