As the Brotherhood prepare their assault on the Celestial Realm, the heroes must train if they have any chance of saving the world!

With the fate of the universe in the balance, the team's only hope lies in someone who stood up to the Jade Emperor before and survived: Monkey King.

The gang gear up and prepare for their own assault on the Celestial Realm.

The universe tears at the seams as MK and friends engage in a final standoff with The Brotherhood.

Now with all three rings, the heroes ask Monkey King 'what's next?' But before he can answer, Ne Zha arrives, hunting them down. While Monkey King holds Ne Zha off, MK and the heroes must get the rings to a mystic mountain where they can reforge the fire. However, when Macaque arrives, now supercharged with Bone Demon power, things go from bad to worse.

With the heroes' team in disarray, MK and Ne Zha try desperately to stop the Monkey King from confronting the Lady Bone Demon on his own, while Mei learns how to control the Samadhi Fire with Red Son. When MK catches up to the Monkey King, it seems that his mentor might actually stand a chance of defeating her!

Things aren't looking good as the Brotherhood overwhelms the Celestial Armies. Desperate to act, Mei leads the charge in a rescue mission.

It's all over! The New Jade Emperor's power is completely out of control and the universe tearing apart before our heroes' eyes! MK must help his enemy become the hero he believes himself to be before it's too late!

Now that the ritual has been started, it can't be stopped. Worse, something is happening to Mei! Ancient secrets are revealed as Monkey King finally tells the heroes the truth: there is a fourth ring! All of the Samadhi Fire is absorbed into Mei, and there are now two unstoppable forces for the heroes to contend with. The Monkie Kid team is pushed to breaking point, and nothing will be the same!

With the Monkey King under Lady Bone Demon's control and Mei imprisoned in her tower, MK and other heroes formulate a plan to rescue their friends and save the world. With help from Macaque, new information from a depowered Mayor, and the Lady Bone Demon's power stretch thin, this is their last chance to stop Lady Bone Demon!

The final battle between the heroes and Lady Bone Demon has begun. MK must save his mentor from her control and stop her before she can release the Samadhi Fire and destroy the world! When all our heroes embrace their own destinies, the ultimate fight is on. Working together, they have one shot at defeating their ultimate enemy once and for all!

MK is living that hero lifestyle, busting bad guys and saving the day, until he opens a cursed scroll and his world is flipped upside down once again!

When our heroes are scattered to different memories, Mei is captured by a powerful demon, and her family sword is broken!

Trapped in the body of his ancestor, Sandy challenges Pigsy to a fight! Meanwhile, MK meets the wise master who taught Monkey King all he knows.

MK accidentally shrinks himself and falls down the drain, into the sewers, and finds himself back in the lair of the Spider Queen. Trying to escape, MK finds a young girl in need of rescuing. However, she's really Lady Bone Demon in disguise! Meanwhile, Tang has become a food critic, and Pigsy bends over backwards to make sure he's pleased.

After gathering all the secret ingredients, Lady Bone Demon creates a POWERFUL BONE MECH which she uses to attack MK while he is out training. Even though MK has gained new powers, Lady Bone Demon has figured out how to defend against each one and everything turns sideways as MK is defeated! Now our hero desperately needs help to make it out alive, and find some way to come back and save the day!

The heroes arrive at the last stop on the map: Lantern City! But to get the final ring, they'll need to compete in a talent show! Stuck as band manager, Tang doesn't want to just sit around and wait. He's going to find the ring himself! Unfortunately, he's leading the Macaque right to it! To everyone's surprise, Tang stands up to Macaque, tapping into a power he didn't know existed...

The Lady Bone Demon successfully overcomes the Monkey King and now has the perfect champion to complete her 'destiny'. MK reunites with Mei and Red Son, but before they can come up with a plan, the corrupted Monkey King arrives to take Mei and the Samadhi Fire to his new master! Now MK and the heroes will need to fight their strongest opponent ever!

Unable to reseal the scroll, MK's friends become trapped inside! Luckily, a mysterious new hero arrives in time to save Mei and MK from the same fate!

In order to find Tang, our heroes must start their Journey where Monkey King began his! In the company of the great monk Tang Sanzang.

MK has learned the power of TRANSFORMATION! Kind of... When Spider-Bots steal Pigsy's sign, MK needs to use his new powers to get it back! Down in Spider Queen's lair, MK finds she is trying to build a weapon to fight her old ally, Lady Bone Demon. He knows he needs to stop her, but maybe there's hope for his old enemy?

When the heroes' drone crashes in the ocean, they are captured by the Dragon of the East, Mei's distant uncle! Furious with Monkey King for stealing the staff eons ago, he confiscates the map and imprisons the heroes... all except Mei! Now it's up to her to retake the map and save her friends before Macaque catches up to them!

After a pitstop, the heroes get back on the road. Strangely, MK notices they're headed East, not West! Something's wrong! We soon learn Macaque has tricked them and is bringing MK back to Lady Bone Demon. Meanwhile, Pigsy, Mr Tang, and Monkey King realise they've been separated from the others, but before they can go looking for them, they are attacked by a horrifying demon!

MK, Mei and Sandy find themselves stranded in the desert, but a familiar figure emerges to save them: Red Son is back! Bringing the trio to his family's fortress, the heroes overstay their welcome with the villainous trio as they try to find out everything they can about the creation of the Samadhi Fire... and soon realize that the first ring is here, in Demon Bull King's nose!

Kidnapped by Pigsy in the body of his demonic ancestor, Zhu Ganglie, Tang must help Pigsy remember who he is before he's turned into demon-dinner!
