The knights arrive to save a village under early morning monster attack. The knights are pushed back by the many evil creatures, but Merlok 2.0 sends them Nexo Power. With the upgrade the knights defeat the monsters and back in Knightonia King Halberd tries to read them a boring speech. Luckily the knights are called out to save another village.

After yet another defeat Jestro thinks back on his life and all he did before he became bad. We see him try to be a wizard, a knight and, of course, a jester. The Book of Monsters starts training Jestro in evil and they attack a village. The knights arrive to fight and soon have Jestro and the Book of Monsters on the run.

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.

Lance is going to a movie premiere with the King and Queen and Bavaria is also sneaking around. Clay calls from a battle and Lance must run of to help him and the other Nexo Knights.

She successfully fights Lavaria, but has to run off to get to the gala where she arrives in a royal mess.

Robin wants to join the Nexo Knights in battle, but he is too small. Robin starts developing extra legs to make him taller and ends up developing the powerful Ultra Armor. The knights use the ultra armor to defeat the monsters even more easily than before. All cheer Robins great idea.

Lance is annoyed that people think Clay is more chivalrous than him, so he goes off to train himself in the values of a knight. He kind of succeeds through the Nexo Power Champion of Chivalry, but also demonstrates his complete lack of understanding of the whole thing. Besides the part about the shiny armor that is.

Aaron is searching for his shield while Macy moans about him for always making a mess. Two scurriers have stolen the shield, but through the Nexo Power Remote Control, Merlok 2.0 beat them both up and brings the shield back to the Fortrex.

Ava and Merlok 2.0 are trying to get all the NEXO Powers organized, but it is proving difficult. Merlok tells a story about the old kind of magic he used to practice, but Ava pulls him back to reality and shows him how the new kind of NEXO Powers that upgrade the NEXO KNIGHTS heroes and help them defeat Jestro are much, much cooler.

Jestro and his monsters are attacking a village and KNN are there to cover it. For a short while Macy is in trouble, but then she gets the Royal Brawl upgrade and beats up the monsters. It is the first time ever a NEXO Power upgrade has been caught on camera and Herb Herbertson is excited

Lance is having trouble on the set of his latest film ‘Star Fall’ where he plays a knight in space. Nothing makes sense and the set and costumes are terrible. Finally Lance gets enough, upgrades with Nexo power ‘Star Fall’ and wraps everything up perfectly.

Clay is fighting snakes in the Fortrex training room and realizes that he is scared of them. He talks to Robin and Merlok about his fears and gets an idea. Back in the training room Clay has learned to use his fears as a weapon against the monsters.

Macy is out in the woods playing with cute bunnies when Lavaria, Moltor and Flama surprise her.

Now you get the chance to test Robin’s cool, new vehicles to make sure they are ready for battle. But after driving too far away from the Fortrex, you end up in the middle of a Stone Monster attack. You must use all your skills and tech functions of the vehicle to escape.

What’s going on? Have the squire bots developed fantastic new powers? Or have they invented some genius device to battle the monsters? There's something fishy going on here - and it’s not coming from Chef Eclairs kitchen!

It's the day of graduation for the latest class of Nexo Knights, but all does not go as planned as the court jester Jestro decides to use the Book of Monsters to get the respect he deserves.

Power is restored to the kingdom, and Jestro is on the loose. He gains the Book of Evil, transforming into a true villain. Meanwhile, the new knights are having trouble working together to protect the kingdom amidst the chaos from Merlin's demise.

The knights work on their teamwork while the royal RV is converted into the Fortrex, the new headquarters for the knights and a home for Merlok 2.0 and the Nexo power.

Jestro finds the Book of Chaos, and gains chaos monsters to summon, but they won't listen to him. The knights have to stop those monsters while protecting the king and queen, who are giving a tour of the kingdom to business leaders.

In the town of Spittoon, everyone is afraid of everything thanks to the Book of Fear. The Book of Monsters eats the book, releasing Whiperella, whose whips spread a person's worst fear with a single strike.

Lance earns a leading role in 'The Golden Castle' and his friends play in the background. Macy declines but then eventually agrees to do so. When they're filming, Jestro summons a monster called Lavaria, a very sneaky monster; Jestro then takes a liking to her and orders her to find and give the Book of Monsters to eat the script of 'The Golden Castle' and hold its power, which they successfully do. But soon the knights find out, and they get the new Ultra Armour, giving them more powerful weapons, whilst the director is directing all the action.

The knights' go to Axl's home town, Digginton, where they meet his mother, father and little sister, Axlina, who instantly takes a liking to Robin. Soon, they leave to find a new book called The Book of Deception in a massive maze, which doesn't look like what it seems. They eventually find out that Jestro and the Book of Monsters are searching for it too, and it turns into a race to get the book first.

Leaving the maze with the real Book of Deception, Jestro feeds several books of the same kind to the Book of Monsters to create the fake NEXO Knights. They raided and destroyed the city of Bork. The real knights come and all the citizens shooed them off for something they didn't do. Ava and Robin hear the news and are shocked by what they did. The monsters trick the citizens again by turning the Evil Mobile into the knights' Rolling Fortrex. When they tried to raid again, a Black Knight blocked their way and defeated them with ease. King Halbert then contacts the knights and said that if they don't come up with any evidence that they didn't destroy the cities, he'll be shutting them down. Several times the fake knights tried to attack a city, the Black Knight is there and defeats them in less than a few blows. The real knights came in afterwards in the real Fortrex and conquered over their fake selves. Soon, they come to the fact that Robin was in fact the Black Knight in disguise!

Jestro and the Book of Monsters travel to the place where the evil wizard Morstrux did his evil deeds (?) and find the Book of Destruction. Soon, Jestro brings out a whole lot of destructive monsters and split up in different directions. Macy scolded to her dad that she quits being a princess, but he disagrees and that she was born to be a princess (?). When the knights find out that monsters are attacking, Merlok 2.0 told them that they should go together, but they decided to split up; King Halbert hopes her daughter will come back. However, the knights get captured one by one, with no way to escape. When all the monsters were asleep, Aaron quietly escapes, being the only knight to save all his friends before Jestro attacks the castle of Knightonia.

Aaron must figure out a plan to save all his friends. Meanwhile, Macy has a flashback, saying that she wanted to become a knight, not being a princess all the time. Soon, she admitted to herself that she was not ready to be a knight, but was cut off by Aaron, who used his energy bow to cut the chain off of her, and retained her shield and mace back. The two then rescued Clay, who was chained on a target, getting spun around all the time. After him, they saved Axl by giving him a chain of sausages to climb up, but was unsuccessful the first time, and the second time, they succeeded. Finally, they rescue Lance, who was stuck in an animal farm, making a new friend, called Hamletta, a pig. Jestro, who was so close to victory, were stopped by the knights, and the rest sans Clay, got their NEXO Power, and the blue knight got one that was last done ages ago. When Clay got the new NEXO Power, one smash of his sword and all the monsters turned to purple dust, and he slammed his sword down again, and sent Jestro all the way out of the kingdom of Knightonia. Near the end, King Halbert apologizes to Macy, and he claims her an official NEXO Knight. Lance then gets Dennis back on one condition: Lance has to be the servant of Dennis for a week.

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.

The Nexo Knights attend the Gold is Good Ball hosted by Lance's parents in the extremely wealthy town of Arrindale. Unfortunately, Jestro feeds the Book of Greed to the Book of Monsters to make the Lava Monster Army (who are now led by the newly-summoned General Magmar) so greedy, that they steal all of The Richmond's riches (much to Lance's sorrow) along with both of Lance's parents. However, Lance is not as willing to save his parents as they forced him to become a knight in his childhood while Lance wanted to be a celebrity. Meanwhile, Lance's parents believe that Jestro's Lava Monster Army are servants at a spa and as such are completely oblivious of their imprisonment much to the annoyance of the Book of Monsters and General Magmar. This makes Jestro more than willing to return them and the stolen riches to Arrindale.

The Book of Monsters plans to consume a limited edition copy of a Ned Knightley comic book, which will guarded by the Nexo Knights until it is won at a costume contest at Knight-A-Con (this show's parody of the San Diego Comic Con). Robin is also attending the convention using his newly designed Mini-trex (a miniature version of the Fortrex). When General Magmar gets impatient with Jestro's plan to blend in with the attendees, he launches an all out attack on Knight-A-Con which causes the comic book to get lost in a crowd of terrorized attendees. Fortunately, the Mini-trex is able to extend the range of the Nexo Knights' connection to Merlok 2.0, allowing them to obtain their Nexo Powers and find the book. Because of this, Robin wins first prize at the costume contest and thus, he and the Nexo Knights get to keep the comic.

On King Halbert's birthday, Jorah Tightwad decides to prove that the Tighty Knighties are better than the Nexo Knights at King Halbert's birthday tournament, using the Book of Envy as proof that they encountered Jestro. If the Tighty Knighties win, Macy has to kiss Tightwad. If they lose, Jorah has to kiss Lance's "sweetheart." The next day, the tournament is held to see who are the best group of knights in Knightonia. All four Tighty Knighties best the Nexo Knights in the tournament except Macy who is forced to be her father's princess for the day and thus is forbidden to compete. Before King Halbert can announce the end of the tournament, Jestro and the Book of Monsters lead the Lava Monster Army into attacking the birthday tournament. The Tighty Knighties are then shown being completely useless at fighting them and cowering in fear. At that moment, Tightwad reveals the truth of how he obtained the Book of Envy where it fell into his hands when Merlok scattered the evil spell books in the first episode. This distracts him long enough for Macy to take the book from him. After powering up and defeating the Lava Monster Army, the Nexo Knights are declared the true winners of the tournament while Tightwad is forced to kiss Lance's "sweetheart" on the lips. This turns out to be Hamletta much to Tightwad's horror. King Halbert is proud of what Macy did today, saying there's a time for her to be a princess and a time for when she needs to be a knight. Meanwhile, Jestro and the Book of Monsters have succeeded in stealing the Book of Envy which is soon consumed by the Book of Monsters.

The famed Knighton Chef Gobbleton Rambly has created a chili recipe so spicy, the Book of Monsters gains the idea to weaponize it. Knowing this, Clay has Axl and Chef Eclair compete in a cook off with the grand prize being the one cookbook which contains Rambly's chili recipe. When Jestro sends Moltor and Lavaria undercover to compete in the same contest, Eclair has the Nexo Knights seek a pepper so spicy, it explodes if mishandled. Meanwhile, Lance and Aaron hold their own contest to determine which of them is the most resistant to spicy peppers. Despite Jestro's efforts, the Nexo Knights succeed in getting the pepper they need and use it to win the cook off. But unfortunately, their chili ends up being so spicy, it burns the grand prize to oblivion once it was spilled.

The Nexo Knights send Clay on vacation to get some free time. Little do they know that Jestro and the Book of Monsters are on the trail of another evil spell book that is near where Clay is staying on his vacation. Clay soon discovers the staff of his vacation spot has been extremely rude, cruel and nasty to him (doing things such as serving him moldy food and forcing him to tip them for everything) courtesy of the Book of Cruelty. Meanwhile, the Nexo Knights are having fun. Problems arises because they started neglecting their daily duties and they rush to retrieve Clay. Despite his efforts, Clay is captured by Jestro and the Book of Cruelty is fed to the Book of Monsters which gives the Book of Monsters the ability to summon the Lava Monsters Crust Smasher and Flame Thrower. Fortunately, the other Knights arrive and save Clay and Jestro's forces retreat. To the misfortune of the Knights, Clay learns the importance of relaxing just as they had become more diligent.

During a dinner party that the Nexo Knights attend in the town of Cleanington, the Book of Monsters goes to Snottingham (the coldest place in all of Knigton) to consume the literally sickening Snotheiser which makes him and the Lava Monsters he summons very unhealthy. When the Nexo Knights rush to stop the attack on Snottingham, the Lava Monsters sneeze all over them causing them to wake up the next day with the Snottingham Flu (a version of the flu that causes bizarre effects on the victim in addition to usual flu symptoms) causing Clay to hallucinate, Macy to experience severe pins and needles, Aaron to become dizzy and uncoordinated, and Axl to be robbed of his hunger and appetite while the Book of Monsters makes a full recovery. Just before Jestro and the Book of Monsters are able to kidnap King and Queen Halbert, Merlok and Ava send a Nexo Power with an antivirus system added to it which cures the knights of their sickness and allows them to defeat Jestro and the Book of Monsters.

Inspired by Jestro's idol Jokes Knightley, Jestro and the Book of Monsters attend a gig in the village of Funnyton where they pose as comedians. The Nexo Knights also attend and to their surprise, they actually find Jestro hilarious, even attempting to convince Jestro to change his evil ways. However, Jokes Knightley kidnaps the Book of Monsters in order to steal Jestro's act, courtesy of the last evil spellbook called the Book of Betrayal. When the Nexo Knights find the Book of Monsters, it becomes a mad battle for the Book of Betrayal which eventually falls into the hands of Jestro. Not knowing what to do, Jestro runs into the woods and hands the Book of Betrayal to an unseen individual. Evil laughter is soon heard afterwards.

Recapping from the previous episode, the figure who Jestro gave the Book of Betrayal to is revealed to be Clay, who takes Jestro to the Fortrex. When the Book of Monsters attempts to gain the Book of Betrayal and Jestro, the Nexo Knights split up as a diversion until Clay is cornered. Now fully reformed, Jestro sacrifices himself so Clay can escape with the Book of Betrayal. The Nexo Knights then stage a rescue mission to save Jestro from the volcano lair where the Book of Monsters reveals that he is actually the dark necromancer Monstrox, whom Merlok turned into a book and divided his power among eleven other spellbooks. Monstrox adds that he needs Jestro as a host body to regain human form through a ritual in the "Dark Arena", waiting for the Book of Betrayal to corrupt the Nexo Knights. Unfortunately, Clay appeared to have succumbed to its power and begins to bring the Book of Betrayal to Monstrox.

Recapping from the previous episode, Clay hands The Book of Betrayal not because he was corrupted, but to exchange it for Jestro's freedom. Monstrox makes the deal and frees Jestro, but chains Clay in his place to take his body for his own. As part of the ritual, Monstrox regurgitates the evil spellbooks. Meanwhile, the other Knights follow Clay to the Book of Monsters' lair, but are overwhelmed by the Lava Monster Army and reluctantly follow Jestro through the death trap-filled backdoor entrance. Upon reaching Clay, the Book of Monsters nearly completes the ceremony, but Jestro and the Nexo Knights hold him off long enough for Robin to hand Clay Merlok and Techcaliber, which Clay feeds to Monstrox. Overwhelmed by Merlok 2.0's power, Monstrox explodes into energy, destroying his book body while curing Jestro of the Book of Evil's effects. Merlok 2.0 is presumably destroyed as well, but when Robin replaces Techcaliber's motherboard, Merlok 2.0 is revealed to have survived. With Jestro also having been forgiven for his actions and reinstated as court jester, the Nexo Knights celebrate their victory with the rest of the kingdom. When Jestro looks at the sky, he sees Monstrox's face implying the necromancer's survival as a spirit.
