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.

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.

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?

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

Axl is the biggest NEXO KNIGHTS™ hero in the kingdom, but even he needs to power up to defeat evil! When he needs that extra charge on the battlefield, Axl summons The Hammer of Merlok. With this Merlok Power, a giant electric charged hammer falls from the sky in the middle of the screen, flattening enemies, and discharging a wave of golden electrical energy every 3 seconds that damages and paralyzes enemies!

The Knights are tasked with protecting the King’s valuable Ned Knights comic book during the Bookingheim Knight-a-Con. But with all the costumed kids there, will they recognize the real Jestro and Book of Monsters coming to get them?

Rival to the King, Jorah Tightwad thinks his knights – the Tighty Knighties – are easily better than the NEXO KNIGHTS, so he challenges King Halbert to prove who’s better during the King’s Birthday Tournament.

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!

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.
