Aku resolves to do something about The Samurai once and for all and lures him into a cemetery. Then the wizard unleashes hordes of the undead and one of the creatures manages to possess Jack's sword and deliver it to Aku. Armed with the sword and his own shape-shifting powers, Aku runs Jack ragged and then captures him and tries tohug him with the sword...which Jack finally remembers can't be used by the evil to harm the innocent. With the sword incapable of harming him, Jack regains his weapon and drives Aku away.
Made by Genndy Tartakovsky, this cartoon tells the story of a great warrior displaced to the distant future by the evil shape-shifting wizard Aku. The world has become a bleak place under the rule of Aku, segregated into fantastic tribes and ruled by Aku's evil robot warlords. Jack travels this foreign landscape in search of a time portal that can return him to his home time so he can 'undo the future that is Aku!'.
