LEGO: Nexo Knights: The Complete Series (S1-S4‪)‬

It is final graduation fighting exams for the latest Knights from Knights’ Academy. All our new Knights demonstrate their prowess: Clay, Aaron, Alex and Lance. Princess Macy gets to join them, but her father doesn’t want her to graduate. As part of the entertainment, Merlok does an amazing magic trick. His act is followed by Jestro, the King’s Jester. He’s terrible and everyone laughs because he’s a real joke. While Jestro roams the halls of the King’s Castle, forlorn, he hears the Book of Monsters calling to him from Merlok’s library. The book talks Jestro into gathering as many books of spells as he can carry, but they’re interrupted by Clay! As Jestro quickly pages through the Book of Monsters to attack Clay, Merlok arrives. There’s a battle in the library between Jestro and Merlok. Finally, the wizard summons up his most powerful spell in self-defense. Boom! There’s a big explosion and when Clay forces his way back into the library, Merlok, Jestro and the magic books are gone!

When Jestro awakens, he’s been blasted miles and miles away from the King’s Castle by Merlok’s explosive spell. And, it seems, all the books he was trying to steal have been scattered, too. The Book of Monsters broke Jestro’s fall and now he can use the book to attack the people who laughed at him. Meanwhile, the King and his newly-trained Knights pick through the rubble of Merlok’s library. They’ll have to figure something out because Jestro and his newly made magic monsters attack King’s Castle! Clay organizes the Knights to defend the kingdom. It takes all their training, plus the help of an old friend…MERLOK! Only now he’s MERLOK 2.0. Ava has been piecing together what happened and discovering that the “ghost in the machine” she’s been chasing is really Merlok in digital form. Now, he can use his magic digitally and he downloads just the right weapons to the struggling Knights! They finally foil Jestro’s attack with Merlok’s help and officially become NEXO KNIGHTS!

Now the NEXO-Knights get rolling in The Fortrex, their own Rolling Castle! This great new headquarters which houses Merlok 2.0 as an operating system, will be how the knights move around Knightonia and protect it from Jestro and his monsters. Speaking of the evil jester, Jestro uses some newly-made monsters to attack a town far from the capitol where he thinks he’s safe from the Knights’ reach. We see two parallel stories here: the Knights training, learning more about digital magic and getting organized as a team and at the same time we see Jestro making monsters, trying to learn how his powers work and talking to the Book. In the end, the Knights roll up in their castle and defeat Jestro and his marauding monsters.

Jestro finds the Book of Chaos in the countryside and decides he must feed it to the Book. The Book of Monsters actually tells Jestro not to feed it to him; he tells Jestro he’s not ready for that kind of power. But Jestro doesn’t listen. Now the Book unleashes chaotic monsters and Jestro uses them to attack the King and his party who are on a business-related tour of the kingdom. When the NEXO-Knights show up to stop the monster attacks and realize that they must save King and Queen Halbert – Macy’s parents – from the chaotic evil monsters that have been unleashed. Clay asserts himself as leader and brings order to the knights from the chaos. He has his own book: the Book of the Knight’s Code. They should all live by it.

Searching through the dark forests of the realm, Jestro finds “The Book of Fear.” It’s pretty scary. But he feeds it to the book of Book of Monsters, and he uses it to call forth the Whipperella, a monster that can induce fear. One-by-one she uses her knightmarish power on the knights and they experience their own worst fears. Clay fears not living up to the Knights’ Code. Lance fears being a nobody. Macy fears never being a knight and Axl fears having no food. Aaron must take the lead because he’s fearless; he does everything with reckless abandon. It’s not until he leads the group out of the forest – as they fight off the Whipperella – that they we find out Aaron’s true fear – the fear of peace and quiet and no more challenges or high energy escapades.

Lance agrees to star in a movie about remake of a classic film in Knighton: “The Golden Castle.” While pillaging a village, Jestro and the Book of Monsters see a movie poster for “The Golden Castle” and the book says the legendary Golden Castle is filled with riches! Jestro explains that it’s just a dumb movie and that it’s not real. The Book, who’s been shelved for many years, wants to eat the movie script to learn more about the modern world. On the set of the movie, Lance has invited the other Knights to act as extras. When they see how Lance is being portrayed, they’re incensed. When Jestro attacks the movie set to get the script for his book to eat, the film director keeps rolling. This battle footage is fantastic! The Knights defeat Jestro even though the movie set is trashed. The director will make it work. At the premier of the movie, Lance is embarrassed to see that he’s been reduced to comic relief for the realm’s bravest Knight…Macy! The director has now made her a star.

The Knights travel to the Hill Country in the northern part of Knighton to Axl’s home town of Digginton (where they realize that all of Axl’s family look just like him.) While they’re there, Merlok 2.0 detects something…one of the Magic Books! It’s “The Book of Deception”. They go to find it and discover it ended up under a mountain. To make matters worse, the magic book has built a maze around itself to keep it from being found! As the NEXO-Knights enter the maze from one side, Jestro enters from the other; the Book of Monsters has led him to the maze to get The Book of Deception, too. It’s a race through this confusing maze to see who can get the book first. Ava figures out the maze is the Whackman maze from a videogame. After help from Axl’s people to defeat Jestro and win the book, the knights discover it’s a Fake Book of deception. The Book of Deception created a fake copy of itself!

Jestro, happy he has the real Book of Deception, uses it to create bad versions of the NEXO-Knights. The “fake” knights then attack villages and hamlets. When the real NEXO-Knights arrive, they’re booed and pelted with food. Why does everyone hate them? To make matters more confusing, a giant Mech Suit in black – The Black Knight – appears to defend the kingdom’s villages from the fake knights. The Black Knight ends up being very powerful and throws Jestro and his fake knights for a loop. He’s cool and mysterious. But when the fake Knights get the better of him, the real NEXO-Knights appear to fend them off and learn their deceptive secret. The Knights save the Black Knight and they open him up to find young Robin! He used a deep, deceptive voice! The Knights realize that Robin has potential but also still has some learning to do.

In a dark, destroyed part of the kingdom, Jestro arrives at the ruins of a huge castle. The Book of Monsters knows this place, as the great evil wizard Monstrux lived here. The Book sniffs out some powerful magic in the ruins: “The Book of Destruction.” With this, The Book tells Jestro they can destroy the NEXO-Knights and then attack the King’s Castle and cause massive destruction. Jestro creates destructive monsters and sends them all over the realm, so the Knights must separate and fight single combats all over the place. They Knights lose these battles and learn that they must work as a team! And, just when the Knights are scattered across the Kingdom, Jestro attacks the King’s Castle! It looks like all is lost. When Aaron, who has escaped, returns to see Jestro’ attack, he realizes he must gather his fellow Knights. Merlok says it’s very dangerous, but Aaron says he must take the risk to gather the Knights and save Knighton.

Jestro, while still attacking the King’s Castle, has second thoughts until the Book of Monsters orders the mad jester to feed him another magic book. It’s the powerful “Book of Revenge!” Now, combining the powers of Revenge and Destruction, Jestro and his monsters will get their vengeance on King Halbert and the Kingdom of Knighton. Jestro and his monsters lay siege. Will they destroy the castle? Meanwhile, Aaron races across the Kingdom gathering the NEXO-Knights one at a time. As each Knight rejoins the group, they become a more and more powerful team. They even get Robin to join them, as the Black Knight, in his repaired power suit. Our Knights arrive, finally regrouped, fight off Jestro, save the castle and the King. It’s a glorious victory! The King is so pleased after seeing how the brave NEXO-Knights saved his kingdom, he allows Macy to join them as an official NEXO-Knight.

As the Knights battle Jestro, they discuss the fact that Jestro never wins and that they’re always getting over on him. Despite defeating the jerky Jester and his evil Book, Merlok 2.0 discovers that something about the attack on the village is tied to the Knights’ Academy. It wouldn’t hurt for the Knights to go “back to school” to watch for Jestro and for some refresher training. Merlok is sure Jestro wants something at the Academy. The Knights are very much “fish out of water” at the academy. When Jestro attacks, the Knights help organize the students and there’s a big fight versus Jestro and his Monsters. They drive Jestro off without letting him steal any books! Victory! But as Jestro leaves, we see him holding what the Book of Monsters really wanted: a snow globe with a castle in it that was sitting on the librarian’s desk. In the Lava Lands, Jestro throws the snow globe into a volcano and it frees the massive Castle of Monstrux from its snowy magic prison.

Jestro’s not sure what to do with his new castle in the Lava Lands. “Every castle needs a big chamber filled with treasure” says the Book of Monsters so they’ve got to go out looting! The BOM convinces Jestro to call forth GENERAL MAGMAR, and Jestro appoints him as “general manager” of “castle operations,” much to Magmar’s dismay. Meanwhile, Jestro and the BOM find the BOOK OF GREED. This will allow them to make greedy, rapacious monsters that will bring them all the treasure they want to fill their castle! They’ll head to the richest town in the realm – AUREMVILLE! Meanwhile, in Auremville, the NEXO-Knights arrive for a huge “Gold is Good” ball at Lance’s house. When the Monsters finally arrive in Auremville, a battle breaks out and the greedy monsters make off with everything…including Lance’s parents, Goldie and Cuthbert Richmond who are clad in the finest golden garments and so look valuable! Lance will now be forced to live…poor.

King Halbert instructs the Knights that they must take his valuable Ned Knights comic book to the “Knight-a-Kon” in Bookingham. It will be the first be first prize at the Knight-a-Kon. But the Book of Monsters wants the book, too. Having devoured Ned Knightly comic books in it’s down time it has become fanatically obsessed with the storyline. General Magmar suggests they simply attack the place and take what they want, but Jestro tells them they can’t: everyone will be in costume and they’ll be thousands of comics there. This calls for a clever “infiltration” mission (which will also allow Jestro to see the Kon, which he’s always wanted to do.) So Jestro goes into the Kon with the BOM and some monsters. And it’s easy because everyone is in costume; Jestro, the BOM and their monsters fit right in at the convention and Clay and crew have their work cut out for them trying to separate fiend from fan.

It’s the King’s birthday! To celebrate, the Queen and Macy always throw him a great, big birthday party consisting of a feast on birthday eve and a tournament the next day. At the birthday banquet is JORAH TIGHTWAD. He’s goading the King and going on and on about how his knights are better than the NEXO-Knights. The next day, the NEXO-Knights square off against Tightwad’s knights. Tightwad makes fun of the NEXO-Knights as his knights do well. Jestro and the Book of Monsters discover that Tightwad has the Book of Envy and he and his monsters attack the tournament. Then we learn that Tightwad’s knights might be good tournament fighters, but they can’t handle real fights and the NEXO-Knights must save them! The NEXO-Knights successfully defend the king, but Jestro gets away with the Book of Envy.

Knighton celebrity chef GOBBLETON RAMBLEY announces that he’s developed the hottest chili recipe ever created. Now, he intends to give the recipe to the winner of his “Hottest Chili Cook-Off Competition” cooking show on Knighton TV. He’ll turn over his famous Chili Cookbook with the hottest chili recipe on the last page. It’s so unique it can’t be recreated without it. Jestro and the Book of Monsters think they MUST have that recipe. “Hot chili makes hot monsters!” Merlok knows that this recipe, in the wrong hands – meaning Jestro’s – could be dangerous. But when the Knights appeal to the egomaniacal chef, he says the only way to get the recipe is to win it from him. So Axl and Chef Éclair decide to enter. The team that creates the hottest chili will win Rambley’s cookbook. Chef Éclair is unsure that Axl has the skills to help them win the competition, but, as we see through funny cooking show bits, Axl is quite good and they become a pretty good team.

Clay needs a vacation. Or, actually, the knights need a vacation from Clay! Clay is so super-focused that sometimes they just can’t take it: training, training, maintenance, the Knights’ Code tests then…more training. Even Merlok 2.0 is exhausted and he has no physical form! So, the Knights send Clay off on a holiday against his will (arranged by Lance because if there’s one thing he can do it’s plan a vacation.) But unbeknownst to the other Knights, Jestro and the Book of Monsters are tracking an evil book. A book that they suspect is located near the resort “Exalted Towers” renowned for its exquisite service, where Clay is staying. It’s the BOOK OF CRUELTY and Clay notices that it’s affecting the “high class” resort where Lance has booked him: the service is terrible, the staff is nasty, and everyone seems to take joy in being cruel to him (and to each other).

King and Queen Halbert have journeyed to the town of Cleanington to open the brand new Scrubbery Barn at the invitation of Roger the Scrubber. Meanwhile, the Book of Monsters drags Jestro to Snottingham – one of the coldest places in Knighton where everyone coughs, has a runny nose and is generally under-the-weather. The BOM demands that Jestro feed him a “snotheiser” ball which will probably make him sick. The BOM explains that if he is sick, he may just produce a whole new breed of magical monsters … some that the knights would NEVER expect. The BOM gets sick and starts coughing up phlegm globlins and bloblins. The Knights arrive, alerted to what they think is an attack on the town by Snottingham’s mayor, Hack Coughmeier. The sickened, sneezy, snotty monsters infect the knights and, more importantly, the knights’ NEXO-Shields. Now their NEXO-Powers are infected.

Jestro and his monsters are in attack formation moving to pillage the town of Funnyton. But when they arrive, ready to tear into the place, they see that nobody’s in town. Then, they hear…laughter?! The entire town is there listening to a stand-up comic JOKES KNIGHTLY. He’s hilarious. He commands such power, such attention, and such loyalty. Jestro and the BOM decide they must become funny. They order all kinds of book on comedy from Spamazon: books on parody, irony, insult humor, slapstick, satire, knock-knock jokes, elephant jokes, “my monster is so fat” jokes, etc. They work-up a ventriloquist act with the BOM sitting on Jestro’s lap. They start doing their act and, surprisingly, they’re funny. They’re very funny. The Fortrex arrives and the knights rush out, ready for battle. They fight through a string of monsters just outside the town, but discover they’re only working as “bouncers” to keep too many people out of the comedy club.

We finally REVEAL that Jestro has given the Book of Betrayal to…Clay. He tells Clay what it is and how Mike Knight used it. And it seems that the Book of Monsters believed it to be the final ingredient in some ‘Master Plan.” Suddenly, they realize Monsters are after them! Clay retreats with Jestro and the Book of Betrayal to rendezvous with the other Knights at the Fortrex. The Fortrex isn’t fast enough; they’ll need their own vehicles. They decide that they need to split up and go in multiple directions to make the monsters expend their resources on a chase. It’s a huge chase, being covered like a crazy news event by the Knighton News Network. We see a montage of the monsters stopping and capturing all the Knights vehicles. However, as they do, they realize that the Knights have used Squirebots in Jestro Fan Jester hats as decoys. They think Axl has the Book of Betrayal in his BRICK containment unit, but it turns out to be the Ned Knightly Comic.

The Redoubt of Ruination readies the final ceremony to call forth MONSTRUX, the arch-necromancer of the past. Clay, holding the Book of Betrayal walks to the gates of the spooky place. Inside, Clay hears strange…singing and music. It’s like a twisted Broadway show of some kind. Meanwhile, the Knights all realize Clay is gone and so is the Book of Betrayal. Macy says Clay must be up to something. They have to trust him and, more importantly, they have to find him. At the Redoubt of Ruination the ceremony has already begun! The Book of Monsters wants the final ceremony that calls forth Monstrux to be like a really great show! The BOM then barfs up all the BOOKS OF EVIL into their places around Jestro. He’s just missing the BOOK OF BETRAYAL, which Clay has.

A storm is brewing over Knighton. Monstrox has taken the form of a cloud, and is raising an army of lightning infused Stone Monsters. His first target is the new Lavalands Amusement Park.

The Cloud of Monstrox and Jestro unlocks a mysterious Forbidden Power. What kind of havoc will they unleash? And can Merlok 2.0 and the NEXO KNIGHTS make the new COMBO NEXO Powers work?

Jestro and the Cloud of Monstrox encounters the sculptor. He helps unleash a horde of fierce garden gnomes on Knighton. What will the NEXO KNIGHTS do against this new enemy? Will their new COMBO NEXO Powers do the trick?

Jestro and the Cloud of Monstrox unleashes the Forbidden Power Ravaging Rot on Knighton! Turning everything into green gooey rot. But Robin has an awesome new invention that could help the NEXO KNIGHTS

The NEXO KNIGHTS have their powerful shields stolen by Robot Hoodlum and his Merry Mechs. And something is coming to life in the Petrified forest, and it doesn't like knights. Can the NEXO KNIGHTS deal with this without their shields?

Villagers are being enslaved to dig out three ancient warriors whom the Cloud of Monstrox wants to bring back to life. Can the NEXO KNIGHTS make their COMBO NEXO Powers work inside a mountain?

At K.O.M.A. (Knightonia Official Museum of Art) Monstrox learns that a Forbidden Power tablet is hidden. And he will do anything to get it. Especially if King Halbert is happens to visit at the same time. The NEXO KNIGHTS must save all!

The old Lava Monsters are back! And a Forbidden Power is in the middle of their new village of Burningham. But whose side are the Lava Monsters on?

Macy is mad! The three Harpies have kidnapped her mom Queen Halbert. The NEXO KNIGHTS use everything in their power to rescue her. But is kidnapping the real plan or is the Cloud of Monstrox after something else?

The Cloud of Monstrox is growing more and more powerful with every Forbidden Power Jestro inserts. The capitol of Knighton is under attack. The Fortrex is damaged and Clay is turned to stone. Dark clouds are truly gathering over the realm.

Clay is turned to stone and everyone is gloomy. Especially King Halbert. Aaron organizes a party to cheer everyone up. The King wants a reenactment of Clay’s heroic rescue of the Queen. The Knights get a remote control for Clay’s battle suit to “perform” as Clay. Lance quickly gets into the role of the uptight knight of knights. Ava is working on reinstalling Merlok 2.0 into the Fortrex. She is also preparing for a visit from the new Knights’ Academy novices. It is a fieldtrip with Principal Brickland and Sir Griffiths with the goal of teaching the kids about new high-tech battle strategies. It quickly turns into a trip back memory lane for the two. This is an excellent moment for Jestro to cheer up the defeated Monstrox. Unfortunately, for Jestro, Ava is able to make Merlok 2.0 functional, and the Novices defeat Jestro and his monsters using the NEXO Power: Wedgie of Doom. Apparently, this is just what the doctor ordered for Monstrox. A good laugh at someone else’s expense.

The Cloud of Monstrox and Jestro are able to unlock the forbidden Power Shocking Scare and unleash an attack on the village of Bravington. Knights in their new vehicles rush to the rescue and are able to defeat him with a new Combo Power. In the heat of the battle, the Cloud of Monstrox sees the stone statue of Clay and zaps him to life! Clay is now turned, and is fighting against his friends. It is impossible for them to defeat him without destroying him for good. The Cloud urges Clay on. He attacks the Fortrex in order to get to Merlok. Robin in his Black Knight Mech is trying to stop him, but to no avail. Merlok 2.0 is left undefended. At the very last moment Merlok 2.0 unleashes a blasting spell that sends Clay far far away.

Clay as the Gray Knight wakes up far away in a place called Nothing Hill. A poor town where they literally have nothing. They harvest dust. Jorah Tightwad though has found that there is gold underneath the town. He convinces the confused Clay to help him put pressure on the poor townsfolk to give up their lots. This is an easy job for the strong Gray Knight. The NEXO KNIGHTS finally track him down and tries to convince him about who he is. But to the Gray Knight they are still his enemies, and a giant battle ensues in order to subdue the Gray Knight. At last, only Macy is left. When she begins to recite the Knights Code, some words and their meaning are able to get through the stone hard shell of the Gray Knight and the Evil that clouded him seems to disappear. Together they are able to return the ownership of the town to the villagers.

Since the Cloud of Monstrox and Jestro are unaware of Clay’s situation, the NEXO KNIGHTS decide to let him go undercover and infiltrate the Stone Stompers. Clay gets the help of Jack Shield who is his majesty’s secret agent specialist in infiltration and espionage. Clay trains in how to remain silent and unnoticed, a challenge for a man in armor plates. Robin is intrigued by all the cool agent gadgets and follows Clay from a distance. Clay convinces Jestro and the Cloud of Monstrox that he is still evil. Jestro spills their scheme of using the Forbidden Powers to unlock the Stone Colossus. They find Robin spying outside their camp. Clay lets him go and his cover is blown. He gets captured by General Garg. Luckily, the Nexo Knights have been following ready to intercept. They free Clay and fight the Stone Stompers. In that fight Clay goes “berserk” and the Knights are shocked by his behavior. When he fights Ruina (Witch) something holds him back. We are left wondering how that can be.

The Gray Knight ambushes Jestro’s monsters and destroys them. His mission – seek vengeance for the good of the Kingdom. Meanwhile, Jestro and the Cloud need more minions. They find the FORBIDDEN POWER of DEVIOUS DEMOLITION. Arnoldi chisels faces onto rocks and the Cloud of Monstrox brings them to life with his evil lightning. Now Jestro has a quick, make-shift army. Clay is nowhere to be found. Forced to deal with Jestro’s army, the Knights come across the Big Rockowski, a legendary demolition expert. He’s been living peacefully in a little valley with his pet rabbit, Bunny. He’s not sure he wants to help until Bunny’s entire family show up at his rocky plateau in the Halps. Jestro has destroyed their forest. Rockowski agrees to help and they defeat Jestro’s army. The NEXO Knights keep their promise and help replant the forest for Bunny. Meanwhile, Clay has changed; he’s now the avenging Gray Knight and he will make his enemies pay.

Jorah Tightwad digging up a large portion of his property near his castle to build a vault for his money. What the Tighty Knighties – who Jorah employed to dig this vault – find as they dig is a whole bunch of STONE WARRIOR STATUES. There’s even a statue of their leader, GENERAL CRACKENSKULL. Tightwad decides to sell them to Jestro and the Cloud of Monstrox, who, he’s heard, need an army. Jorah gets gold and the Cloud brings the Stone Warriors and Krakenskull to life! (They promptly steal back the money Jestro paid Jorah AND make off with all the other money in Tightwad’s vault!) Jestro and the Cloud use Krakenskull and his warriors to track down the Forbidden Power of CRACKING QUAKE. They then use this power to…attack the NEXO Knights! The Knights are almost overwhelmed until…Clay returns! He saves the NEXO Knights. During Clay’s attack, Ruina Stoneheart gives him Monstrox’s “charm” bracelet. It seems to make Clay even stronger (she’s tempting him to join their side)

Clay pledges to King and Queen Halbert to save their kingdom. As he goes off on his quest to destroy Jestro, the NEXO Knights try to stop him. Clay just isn’t being Clay. Meanwhile, Jestro and the Cloud of Monstrox track down THREE more Forbidden Powers. They need one more FP to bring the Colossus of Ultimate Destruction to life! Clay goes after Jestro’s monsters with a cold vengeance. Not even the Cloud can stop the Gray Knight with his lightning! Suddenly, Ruina Stoneheart leaps in to defend Jestro. “I know how to stop you, boy,” says Ruina. “Because I’m your mother!” The shocked Clay is blasted back. The NEXO Knights drag him away. Clay is stunned, hurt and angry; so angry he says he can’t be trusted. He insists the NEXO Knights contain him. They take him to the Fortrex and put him in a magical containment field, but he escapes. He “attacks” Macy, provoking her to call down a NEXO Power. She turns him to stone again. Macy looks at Clay’s statue and she’s devastated.

Clay is locked in the Command Center, as a statue. Merlok uses a powerful spell to reverse the stone in Clay’s body. Clay becomes human again. Macy comes and begs forgiveness and Clay says it’s not her fault. It’s MERLOK’s fault. Merlok finally must explain Clay’s past. Merlok tells him, Ruina is his mother. Her real name is MERGANA and she is Merlok’s sister. She turned evil and Merlok took Clay away to protect the boy. Merlok then turned Ruina into a statue. She was unearthed in “Mergana’s Garden” by Jestro’s minions. But no time to lose…the FINAL Forbidden Power is in play and it’s the most powerful one yet: AWESOME ANNIHILATION! They find it near the town of Strongheim. Jestro locks the last Forbidden Power into the Standing Stones at Mt. Thunderstrox. The Standing Stone Crown powers to life and the GIANT COLOSSUS of ULTIMATE DESTRUCTION rises. The Cloud of Monstrox goes INTO THE COLOSSUS, imbuing it with power. The Colossus now has the evil face of Monstrox.

The Colossus marches across the land, destroying all in its path. The NEXO Knights don’t know how to stop it. In the meantime, Merlok dispatches Robin to Merlok’s Tower in the capitol to complete his secret project. Clay is off, somewhere, finding himself. He’s confronted by…Mergana, his mother. Why fight Monstrox, she asks him? Join them! Clay thinks on this. Meanwhile, the Knights try to battle the seemingly unstoppable Colossus Monstrox as it marches towards Knightonia. Just then, Clay returns. He will lead the knights against this threat. THEY’RE HIS FAMILY! With Clay at the lead, the Knights scale the Colossus in BATTLE Suits trying to reach the head. Ava and Merlok have determined that they must destroy the Forbidden Powers in the Colossus’ crown. Clay and Macy try to attack the FPs in the crown, but the Colossus shakes them all off. Jestro arrives with Mergana and she uses her magic to drive them away from the Colossus, which can finally see…Knightonia.

The Monstrox Colossus attacks the city! The entire city has turned out for defense as Robin continues his secret project in Merlok’s Tower at the castle. The King and Queen and Brickland and Sir Griffiths are seeing to the city’s defenses – all being coordinated by Clay from the Fortrex. As Jestro and Mergana with a horde of monsters arrive just in time to see the Colossus crush the Fortex! It smashes it to bits! They finally find out what Robin is working on…turning Merlok’s Tower into a ROCKET to fight the Colossus! Clay says they must launch the Rocket Tower as their last hope. But before they launch, they get a call from Ava. She’s got another passenger for them…Merlok steps out of the battered Fortrex in Robin’s old Mech and is now…MECHLOK! He can now directly use his powerful spells in battle! Finally, the Rocket Tower launches and the NEXO Knights, in Battle Suits, attack with Mechlok and battle to bring the Colossus down!
