Created by Genndy Tartakovsky, Samurai Jack originally aired on Cartoon Network from 2001 to 2004, comprising four seasons. The series follows a young samurai (voiced by Phil LaMarr) who is cast into the future by the evil shape-shifting demon Aku (voiced originally by Mako) mere moments before defeating the demon. He adopts the name Jack and continues his fight in the dystopian future ruled by Aku. Jack seeks to find a portal back to his time but is constantly thwarted by the demon’s forces. The series was left open-ended after the conclusion of the fourth season. Tartakovsky previously expressed interest in a film adaptation of the series to provide a genuine conclusion, but the project never materialized.
The fifth season of Samurai Jack is the final season of the animated series. This season of Samurai Jack follows Jack on a journey that concludes his story. It premiered on the Toonami programming block of Adult Swim on March 11, 2017 and concluded its run on May 20, 2017. The announcement of the season came in December 2015, eleven years since the series was originally concluded on Cartoon Network. Genndy Tartakovsky, the series’ creator, returned as a director, writer, and storyboarder for this season. The season received universal acclaim from critics, praising it for its more intense and mature tone.
