When a gang of robot bikers destroy his sandals, Jack seeks revenge, but realizes that he can’t do so without footwear, something he has difficulty choosing.
Three short stories about some of Jack’s confrontations. He confronts a two-headed riddling worm, a family that feeds on metal, and a gargoyle who is imprisoning a fairy.
While ascending a mountain, Jack encounters a hidden society of warriors who have fought a nearly 500-year war against an army of robots and offers to help them put an end to it.
Angered by the failure of his bounty hunters and mercenaries to defeat Jack, Aku uses the samurai’s inner darkness to create an evil clone whose sole purpose is to destroy him.
The samurai is plunged into a dystopian world ruled by Aku, adopting the name “Jack”. After getting in a fight at a nightclub, he is hired by a group of canine miners to protect them from Aku’s forces.
After his lack of jumping skills cause him to lose a chance to return home, Jack helps a peaceful tribe of apelike creatures and their human leader defend themselves against the attacks of a larger rival tribe in return for lessons on how to “jump good”.
Jack is transformed into a chicken after bumping into a cranky wizard and winds up being captured by a greedy man (Luther Creek) who seeks to turn him into a prizefighter.
When Aku catches a cold and spreads it to Jack, Jack is accidentally infected with Aku’s evil. Jack desperately seeks out a cure before Aku’s essence transforms him into the monstrosity himself.
Centuries ago, the demon Aku is accidentally released by Jack’s father, who receives a magic sword from the gods. Eventually, he uses the same sword to imprison Aku beneath the earth.
Seeking to weaken Jack’s popularity among his subjects, Aku gathers the children of the world in his palace and tells them a series of “fairy tales”, all of which portray himself as a hero and Jack as the villain.
Jack rescues a baby from hungry ogres, but then trying to find the child’s mother while caring for it and protecting it may be his greatest challenge. During the episode, Jack retells the story of Momotaro to the baby.
Seeking to end their struggle, Aku proposes a one-on-one duel between him and Jack, with neither combatant using their magic abilities. Jack agrees, but Aku’s honesty is unclear.
