Jackie, Uncle, and Jade must find the demon and annihilate it before Asia is dismantled. Uncle makes a magic potion that allows Jackie to penetrate Shendu's skin to steal the twelve talismans back.

Captain Black, the J-Team, and some old adversaries put their differences aside to come together in order to stop Drago who is on the verge of conquering the entire world.

The Tiger Talisman splits the dark and light sides of Jackie in two, which makes it easy for Valmont to trick his dark side into working for the Dark Hand. The light Jackie could not do anything, he does not want to fight, while the dark Jackie steals the 12 talismans from Section 13. Both halves fight for the talisman, but Valmont gets to it first and uses it to turn Shendu into it's old self again, an alive, giant dragon demon.

Jade pleads Jackie to let them enter the contest held on Boru Island, but Jackie explains that this is a serious mission. However, on the set, the producer mistakes Jackie, Uncle, Jade, and Tohru as a competing family. They must face off against the Dusseldorf family, but they fail in the first task when Tohru falls off the bridge after being pelted by coconuts. However, it is Uncle who is voted out of the family, but he manages to stay on the island for the night after complaining about his supposed fear of flying. In the second round, neither family wins the bug-eating contest, so they must race in the tie-breaking round. When Jackie, Tohru, and Jade near the finish line, Drago appears, manages to obtain the Water Demon chi, and creates a tid

Before Bai Tza can use another flood, Uncle uses a gourd from one of the Immortals to seal her away again. Unfortunately, Jade steps too close to the chi spell and is dragged into Bai Sa's portal. Meanwhile, the Demon Sorcerers communicate with and confront Shendu. In order to escape punishment, he promises that all seven of the Demons can use his own Portal – the only one left – to come back to Earth. A race against time ensues as the Chans work from both sides to both recover Jade and close the last portal for good.

Valmont returns and gives Tohru a magic potion that causes the man-giant to loose his memory. He awakens at Valmonts hideout, and 'remembers' who he is - #1 Enforcer. Uncle creates a locater spell for the missing Tohru and the gang tracks him to India. Tohru believing Jackie to be his enemy, engages him in battle. Triumpant, Valmont and Tohru continue to the Temple of the Golden Elephant. At the temple, Jackie attempts to stop Tohru from stealing a jewel encrusted elephant that will finance the Dark Hand back into action. The removal of the Elephant causes stone statues in the temple to animate. Tohru and Jackie work together to defeat the animated statues while Valmont hides.

Jackie, Uncle, Tohru, and Jade discover that they have overlook something in the ancient writings by making the horrible mistake of placing the final oni mask along side the other eight in Section 13. By doing this, they have released Tarakudo and his generals from the masks that bind them. The entire world begins to be engulfed in total darkness as the shadokahn are now free to walk the earth.

Drago breaks out of Section 13 on a mission to absorb the demon chi that is held in the original artifacts used to defeat the demons so many years ago. He finds the Enforcers at a petting zoo and transforms them into dragon-human hybrids. Drago locates the fan that holds the chi of the Wind Demon. Meanwhile, Jade gets into the nasty habit of burping. Jackie and Captain Black hunt Drago down to a Chinese-themed car wash, where the fan is located. Unbeknownst to everyone, Jade absorbs the demon chi. At school, her burps create powerful wind storms, and she begins to transform into a frog.

Realizing what has transpired, Shendu and the other three remaining Demons make a final stand at Australia to prevent history from being corrected.

Jackie finds a highly valued cat statue. Anyone who is scratched by it is magically transformed. Forced to steal it back for a gangster when Jackie is tossed into a jail cell, Jade is able to retrieve the statue, but gets scratched by it in the process. Uncle had been researching into the Cat’s legend, and says that the cure lies within. Jackie soon has an epiphany, and decides the Cat is too dangerous to be in a museum. So he smashes the statue, thus releasing a purple-colored gas that cures Valmont and Jade. With that, Jackie then realizes that “The antidote lies within” meant that the antidote was inside the statue itself (and not within a person, despite what he thought at first).

The Enforcers and Daolon Wong both break into Section 13 in search of the talismans. Uncle capture the Dark Chi warriors in a magical urn. Jackie destroys the talismans rather than allowing them to fall into the wrong hands.

Dalon Wong later turns the Enforcers into his new Dark Chi Warriors. The first power that Jackie and team track is the power of Imortality, which leads them to a local dog show.

God Q captures out heros on the outskirts of a nearby village. Daolon arrives to take the rat for himself. Jade manages to change the marking on Daolon's forehead to resemble that of Xolotl and convinces God Q that Daolon is the real enemy, not El Toro. Grabbing the rat from Daolon, Jade runs into the village and animates the Super Moose plush toys being sold there. The Super Mooses free Jackie and the others. God Q defeate Daolon and learn how he was brought to life, and agrees to be returned to a statute.

Daolon Wong releases Shendu from his etheiral enprisonment in exchange for the talisman power of the Dragon - Combustion. Jackie, Uncle, Jade and Thoru attempt to stop Shendu's return to earth but fail. Shendu goes back on his deal w/ Dalon and absorbs the Dragon power for himself, and then drains Dalon of the tailsman powers he holds. Shendu persues Jackie back to Section 13 where the other talisman animals are. Before Shendu can absorb their powers, Jackie and Jade flee with the animals. Shendu stops Jackie and Jade at the zoo. Depsite Jackie's heroics, Shendu absorbs all of the talisman powers. Before Shendu can finally destroy Jackie, Uncle, Thoru and Section 13 arrive chanting a chi-spell (that Uncle got from Daolon Wong). The spell returns Shendu to his 'original' statue form and the talismans pop-out from his body. The talismans and Shendu are locked up in Section 13's vault for good.

Daolon Wong's failed attempt to escape from prison through the use of magic reawakens Tarakudo, the king of the shadowkahn who is bent on recovering all nine oni masks that imprison his generals. Tarakudo attempts to free himself and his minions so that they can unleash total darkness upon the earth.

Ratso obtains the next Oni mask and has summoned a new deadlier type of Shadowkahn with sharp metallic claws and razor pointed feet that appear to be unstoppable. Meanwhile, Uncle begins to doubt himself as believes he is no longer useful to the group because he is not well versed in Japanese legend and magic.

While attempting to stop the Enforcers from getting the fourth oni mask, it accidentally lands on Captain Black's face. He uses the powers of the mask to help him easily take down the Enforcers. Jackie and the rest of the group become worried when Captain Black becomes very intrigued and excited by his newfound abilities. Captain Black's true good side is able to ward off the influence of the mask for a while, but the dark power of the oni begins to slowly corrupt and take hold of him. When the darker oni Captain Black finally emerges, he attempts to take advantage of his full access to Section 13. Jackie, Jade, Uncle, and Tohru race to work on a way to keep the other three stored masks away from Black as they search for the ingredient needed to perform a removal spell.

The J-Team unites to battle the anti-J-Team, and Jade casts a spell that backfires and turns the J-Team into toddlers.

Drago succeeds in capturing Jackie, Uncle, and Captain Black. He holds them for ransom in order to get the prize that he so desperately wants, the Chi containment unit.
