Samurai Jack

One of the golden age of American cartoons from Cartoon Network, and officially on the Approved Television list for /tg/. A super badass samurai warrior wielding a holy sword attempts to destroy a shapeshifting sorcerous abomination called Aku, but the monster sends him into a distant future where Aku has taken control of the galaxy. Samurai Jack now explores the world, helping those oppressed by Aku's evil minions and seeking a portal to return him to his own time, that he may slay Aku and undo his evil future.
