The Dark Hand goes hunting for the legendary Pan'ku Box which will lead them to the eight Demon Portals. Knowing that the Dark Hand is too strong with the Talismans for Jackie and Uncle to handle alone, Jade recruits El Toro Fuerte and Viper, along with the reformed Tohru, to form the J-Team.

Shendu and the Dark Hand find a clue to the first gate that will enable him to release his sister, the Mountain Demon. Jackie goes to Japan to stop them, while Uncle begins to train his new apprentice, Tohru. Meanwhile Jade causes havoc with a duplication spell.

Shendu goes to Hollywood to free his brother the Thunder Demon. Jade tries to make Jackie the next big action superstar in Hollywood as Jackie tries to prevent the demon from returning.

When her classmates get a tattoo, Jade decides to get one also. The design she chooses, however, comes from a magical book, which has unexpected consequences.

The Dark Hand must travel into space to free Tso Lan, the Moon Demon. Jackie and Jade travel along as stowaways on their stolen shuttle and must hold off the demon so Tohru can arrive on the reserve shuttle with the Chi Spell ingredients. With Uncle handling the incantations from NASA Mission Control, they must seal the Demon Sorcerer back in the void before he uses his gravity-manipulating powers to change the face of Earth forever.

Jackie is excavating some ancient armor when Uncle reveals it is the Armor of the Gods. This ancient suit of armor was worn by the Eight Immortals in their battles against the Demon Sorcerers. It proves quite convenient when the Dark Hand travels to Spain to find the portal of Dai Gui, the Earth Demon. However, sealing Dai Gui is complicated, as Jade used a sleeping potion on Uncle because of his constant complaining.

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.

Jackie and gang locate the Ox talisman powers in the Himalayan mountains. Hak Foo smashes his way into Daolon Wong's lair, and demands the Ox talisman from him. Daolon turns Hak Foo into a Dark Chi Warrior and transports them to the Himalayas. Uncle gets 'the willies' and begins a transfer of the talisman powers from the Ox to another vessel. Daolon ventures into the spirit relm to battle Uncle while HakFoo takes on Jackie. Daolon captures Uncle's essense, and discovers that Uncle's transfer spell worked. Jackie and gang return to the Ben-Shui temple, where Tohru and Jade work on a spell to locate the Ox talisman powers.

Jackie goes to Daolon's lair to retrieve the orb containing Uncle's essence. Just as Jade and Tohru determine that Uncle's body contains the Ox talisman powers, Dark Chi Hak Foo smashes into the temple and takes Uncle. Jackie follows and confronts D.C. Hak Foo and Daolon. Uncle returns to his body just in time to use the Ox talisman powers to defeat the bad guys. The t

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.

A new Oni mask has been discovered in San Fransisco. Will Hak Fu finally get to wear the mask? No! Who better than Jade's dog scruffy to command the new tribe of winged shadowkan?

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.

Jackie and the enforcers locate the seventh oni mask at a yard sale where it is eventually bought by a man who owns a site the sales antiques. It is then sold and won by some rich guy who ends up being Valmont. Jackie and the enforcers go to Valmont's apartment to get the mask and there is a big fight. During the fight, the mask is broken in half by Hak-Foo and one half goes to Valmont and the other is caught by jade. Valmont puts on his half and summons half of the shadowkahn.

Jade puts on the other half and summons the other half, which don't have heads). They end up in a building where the two halves of the maske get together and combine the shadowkahn into one so that they can defeat Jackie. While this is happening, Jade and Valmont are trying to get the half masks off themelves because Valmont wants money and the mask wants power. Eventually they get the mask removal potion and take the halves off each other.

After many failed attempts to acquire the power of an oni mask, Hak-Foo finally gets one. He is a disappointed in the small size of his shark like shadowkahn, but Hak-Foo soon discovers their monstrous appetite for devouring shadows.

Jade gets the surprise of her life when she is visited by... herself, from the future! Future Jade is trying to stop Shendu's son, Drago, from getting a bunch of magic dragon's teeth so that he can free his father.

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.
