Season 2

When the Nexo Knights are sloppy in a fight with Jestro, Merlok 2.0 sends them back to the Knights' Academy. Not only for a brush-up but to find out what Jestro is after in its hallowed halls.

When Jestro uses the Book of Greed to rob Auremville of its riches, he also gets Lance's parents as prisoners and these demanding rich folks are too much for even monsters to handle.

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.

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

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

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 funniest town in the kingdom. When they Knights arrive to capture him, they discover to their shock that Jestro and the Book of Monsters are now the town's top comedians!

In a massive chase around Knighton, the Nexo Knights attempt to keep the Book of Betrayal out of the Book of Monster's grip. But the evil book is persistent. Will he get the final piece of his evil puzzle?

The Book of Monsters, having the final pieces of his evil plan in place, tries to take human form. Can the Nexo Knights and Merlok 2.0 stop the greatest threat they've ever faced? Or will the kingdom be plunged into darkness forever.
