Jack and the Zombies

Aku tricks Jack into entering a cursed graveyard and summons an army of undead warriors. Jack defeats them, but a ghostly hag steals his sword and brings it to Aku, who tries to kill Jack using it. As he is about to stab the samurai, Aku discovers that the sword, which can’t be used for evil, can’t harm Jack, who takes it back and forces him to retreat.
