When Jestro the Jester finds the Book of Monsters, chaos breaks loose in the Kingdom of Knighton. Can the newly graduated Knights from the Knights’ Academy save the kingdom?

Macy is leading the charge into battle! To conquer evil she powers up with The Staff of Merlok! This Merlok Power generates Merlok’s staff which descends from the sky in golden light. Enemies are blinded, and when the staff hits the ground, it sends a wave of force all around that pushes back enemies around the edge of the screen. For 10 seconds the staff sends golden energy toward the nearest enemy. If an enemy is defeated this way, the knight regains 10% of their total HP.

When the other NEXO KNIGHTS decide they need a vacation from Clay, they send him on a holiday not knowing that he’s going to a resort that houses an evil book or that Jestro will be heading there, too.

Power up with The Axe of Merlok and defeat your foes! When Macy is surrounded on all sides by bad guys, she summons the awesome power of the The Axe of Merlok! Watch as 5 spinning axes fall from the sky – 3 from the left, and 2 from the right, and each axe deals area-of-effect damage upon landing. Take a ‘byte’ out of the evil tech infectious bad guys and team up with the NEXO KNIGHTS™ team!

Clay has arrived to the battlefield ready to fight, but he needs some help! Watch him power up by summoning The Crossbow of Merlok with his shield. With this special Merlok Power, a mounted crossbow appears in the middle of the screen and shoots in a circular motion for 20 seconds, dealing area-of-effect damage. Every 3 seconds, the crossbow stops and then starts to rotate again in the opposite direction.

Axl and Chef Éclair must enter a cooking contest to try to keep Jestro from getting the hottest chili recipe in the realm.

Forbidden Power missions are spawned on the map by the zap of Monstrox. See what happens when the knights take on Cosmic. Before starting the mission try out different Combo NEXO Powers to find the perfect one that can counter these Cosmic attacks.

Never fear – Aaron is here! For this battle, Aaron is charging up and using The Sword of Merlok to help him beat these monsters! This Merlok Power creates a giant sword that falls and lands in the middle of the battlefield, causing huge cracks in the ground that deal area-of-effect damage to all enemies. Additionally, golden eggs fall from the sky, crushing enemies beneath them.

Clay takes a walk in the forest. Monsters follow him. He thinks back to when he was young and started dreaming of becoming a knight and did his first heroic act. The monsters attack him, but he thwarts their attack and defeats them easily. Macy and Aaron are mad he got in a fight without them.

The Book of Monsters catching a cold means trouble for the NEXO KNIGHTS when he can create an entirely new kind of “snotty” monster.

The Book of Betrayal leads Jestro and his Monsters to Funnyton – the funnies town in the kingdom. When the Knights arrive to capture him, they discover (to their shock) that Jestro and the Book of Monsters are now the town’s top comedians!
