Monkey King battles the hero Ne Zha for a map that will lead to a weapon strong enough to defeat the Lady Bone Demon. With MK in peril, Monkey King uses the last of his strength to get back, but not before MK loses his powers. Now, MK, Monkey King, and the other heroes are on the run, pursued by the Macaque! Without his powers, MK must make a tough choice in order to defeat the villain!

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.

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 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!

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!

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!

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

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

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

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.

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!
