The trailer describes Unicorn Warriors Eternal as an animated series that’s “a lifetime in the making,” which isn’t too far off from the truth. The series, which premiered at the 2022 Annecy International Animation Film Festival and was previewed at New York Comic Con last October, will premiere on May 4th at midnight on Adult Swim.Ī 10-episode mini-series in the vein of 2014’s Over the Garden Wall, the supernatural steampunk animated action series’ premise sounds reminiscent of Tartakovsky’s own Sym Bionic Titan by way of the 2003 Samurai Jack episode “The Birth of Evil.” It centers on a team of primordial heroes who repeatedly reincarnate throughout history in order to fight an ancient evil. Adult Swim debuted the first trailer for Unicorn Warriors Eternal, the upcoming animated fantasy anthology series from Samurai Jack and Primal creator Genndy Tartakovsky, on Wednesday.
