His armor is blue and his crest shows a hawk (or maybe an eagle), and his signature weapon is a Claymore, which has the ability to supercharge into the "Sword of Strength". Clay rides around in the Rumble Blade, a large vehicle with two sidecars and a plane shaped like a sword that splits off into smaller vehicles. Beginning in "The Cloud," Clay drives the Falcon Fighter Blaster, a fighter jet with bladed wings. Starting in "A Little Rusty', Clay is affected by the Cloud of Monstrox dark magic which is turning him to stone after being hit by the Cloud of Monstrox's evil lightning which also knocked him into a statue causing him and Merlok 2.0 to find a successor until there can be a way to restore him to normal. The transformation is completed in "Rock Bottom" and Aaron covers for Clay until a way to restore Clay to normal can be found. In "The Gray Knight", Clay is reanimated by the Cloud of Monstrox and used to try and destroy the other knights until Merlok 2.0 blasts him away to Nothing Hill. After "The Good, The Bad, and the Tightwad", returns to good. But in "In his Majesty's Secret Service", Clay becomes affected by Ruina's magic causing him to become more aggressive and violent towards the Stone Monsters and others but cannot strike Runia. In "Heart of Stone", it is revealed that Ruina is Clay's mother and Merlok's sister making Clay the biological nephew of Merlok. Clay has incredible magical powers, and re petrified to stop him from hurting anyone. Later on, he regains his human form.

Aside from his shield, his main choice of transportation is a crossbow-shaped fighter jet called the Aero-Striker V2. Upon Clay's transformation to stone, Aaron was made into the new leader for the Nexo Knights until Merlok 2.0 can find a way to restore Clay to normal. After "In Charge", Aaron drives a new vehicle called the Rock Climber.

text: Lancelot "Lance" Richmond[1] (voiced by Ian Hanlin) - Lance Richmond is one of the Knights of Knighton who doesn't always have a positive attitude towards training and usually butts heads with Clay. He is very rich and displays a spoiled personality. His armor is white and his crest is a horse. His weapon is his namesake, a lance. Outside the Fortrex, his preferred means of travel is his Mecha Steed, a robotic horse that can convert into a motorcycle. Both forms possess a larger version of Lance's trademark weapon. In "Greed is Good?," it was revealed that Lance became a knight because his parents forced to become one during his childhood instead of becoming a celebrity. In "A Little Rusty', Lance drives the Twin Jouster that can detach its back half to become faster.

text: Princess Macy Halbert (voiced by Erin Mathews) - Princess Macy Halbert is the one of the Knights of Knighton, the only female in the team. Her parents are King and Queen Halbert where King Halbert initially disagrees with her decision to join the knights. Her armor is red and her crest shows a dragon, and she carries a power mace in battle. Macy's vehicle is the Thunder Mace, a large motorcycle with twin cannons. But in "Rock Bottom', Macy starts using a dragon-shaped vehicle called "Hotspur' that can fly, shoot fireballs, and combine with her battle suit. It is believed that Macy and Clay have a special bond.

text: Axl (voiced by Brian Drummond) - Axl is the Knight of Truth. He is a large man who is one of the Knights of Knighton, loves food, and is the strongman of the team. His armor is yellow and his crest is a bull, and he wields a massive battleaxe. When in need of a vehicle he boards the Tower Carrier, a truck pulling a detachable small tower. Later on, Axl drives a new vehicle called the Rumble Maker, which has large twin drills up front.

text: Supporting characters[edit]

text: Robin Underwood (voiced by Erin Mathews) - Robin wants to become a Knight of Knighton and is a first-year student at the Knights Academy.

text: Ava Prentis (voiced by Maryke Hendrikse) - Robin's friend and the resident tech expert who supports the Knights in their battle against evil. Ava is very sensible despite her young age, and usually assists the knights from the inside of their high-tech base. She has a knack for programming and high tech inventions such as the computer sword Techcalibur which enabled her to upload Merlok 2.0 into the Fortrex.

text: Merlok 2.0 (voiced by Brian Drummond) - A digital wizard that helps the Knights defeat evil by sending them Nexo Powers. Merlok was originally a flesh-and-blood wizard who was the last wizard in the kingdom of Knighton where he was a member of the Wizards' Council. It was magic that saw the defeat of the monster armies 100 years previously. During this time, he was revealed to have a sister named Wanda Moorington who was also on the Wizards' Council before being turned evil by Monstrox and being petrified by Merlok. Wanda being Merlok's sister makes Merlok the uncle of Clay which he refrained from telling upon gaining custody of him and not wanting to tell him until he was older. At some point, he became friends with King Halbert who would turn to him for wisdom upon becoming King Halbert's royal wizard. When Jestro first allied with the Book of Monsters, Merlok used his magic to drive them out of the capital city. The side effect of this magic caused Merlok to be absorbed into the castle's computers as a result. Fortunately, he was soon discovered by Ava. In the form of Merlok 2.0, he gained the ability to digitally transmit his magic to the Knights' weapons and armor to enable them to defeat the monsters. In "The Fall," Merlok 2.0 downloads his form into a digital body that is dubbed Mechlok.

text: Hamletta - Lance's pet domestic pig. She lives with the knights, Ava, Robin, and Merlock 2.0 in the Fortrex. She debuted in "The Book of Total Badness".

text: King Halbert (voiced by Brian Drummond) - The King of Knighton, Queen Halbert's husband, and Princess Macy's father. Despite his position, he is rather timid and inclined to panic or worry at the first sign of trouble. King Halbert loves his wife and daughter but isn't entirely comfortable with Macy being one of the knights, and wouldn't have allowed her to graduate had it not been for his queen's intervention. Despite this, he does his best to aid the knights in their efforts to protect the kingdom including allowing them to overhaul his "Ye Old Royal RV" into their Fortrex base. King Halbert also commands a large humanoid mech when the need arises for him to go into battle.

text: Queen Halbert (voiced by Nicole Oliver) - The Queen of Knighton, King Halbert's wife, and Macy's mother. Unlike her husband, Queen Halbert approves of Macy's desire to be a knight and seems much more confident in tense situations. Macy takes after her mother in terms of both appearance and fighting ability, and the queen is just as handy with a mace as her daughter.

text: Herb Herbertson - (voiced by Brian Drummond) - Knighton's resident newscaster on the Knighton News Network who recaps past events at the beginning of each new episode.

Aaron Bot - The Squirebot for Aaron who is dedicated to Aaron's safety. Ther Aaron Bot can help calculate risk and assert dangerous situations.
Lance Bot - Squirebots who carries a lance.

Dennis - A Lancebot who is Lance's personal attendant where he has taken care of Lance since he was a baby. Dennis quit working for Lance in "The Book of Total Badness," but came back at the end of "The Might and the Magic" on the condition that Lance serves him for once a week. In "Storm Over Rock Wood," Dennis quits working for Lance to join Robot Hoodlum's Merry Mechs.

Macy Bot - A Squirebot who was originally commissioned by King Halbert to teach Macy how to be a princess. Although it has been reprogrammed by Ava when Macy became a knight, it still has some of its old programming left.
Axl Bot - A Squirebot who serves Axl in going back and forth from the kitchen to get Axl's food. Its weakness is that it tends to have a bad sense of direction.

Alice Squires (voiced by Nicole Oliver) - A robot newscaster who assists Herb Herbertson on the Knighton News Network (KNN).
Chef Eclair (voiced by Brian Drummond) - A Chefbot that cooks different meals for the inhabitants of Knightonia's castle. He is considered to be Axl's favorite robot as Chef Eclair never gets tired of cooking for the endless eater.

Robot Hoodlum - A rebel Squirebot who lives in Rock Wood Forest. As the leader of the Merry Mechs, Robot Hoodlum steals from the rich and uses their money to take care of the many forgotten and disused robots that have joined up with the Merry Mechs. Robot Hoodlum is neither bad or good as he and the Merry Mechs represent their own side. In "Storm Over Rock Wood," the Cloud of Monstrox once used his evil lightning on Robot Hoodlum so that he can steal their shields. After Robot Hoodlum was defeated, Robin repairs him and he thanks the Nexo Knights by giving Lance four of his robots as Dennis joins up with the Merry Mechs. He is a parody of Robin Hood.

He was robbed of the Book of Envy in "The King's Tournament" by Macy who in turn lost it to Jestro's forces. He harbours a hatred for the Nexo Knights in the fourth season due to the fact that they tend to foil his illicit attempts to make money for himself.

The Tighty Knighties - Tightwad's servants who serve as his counterparts of the Nexo Knights. Although they appear to be skilled with their weapons in tournaments, they are actually cowardly and inept at combat against Jestro and Monstrox's forces. Their names parody those of real-life celebrities.

text: Villains[edit]

text: Jestro (voiced by Vincent Tong) - One of the major antagonists of the series. Jestro was once the king's court jester, but was constantly laughed at due to his clumsiness and not laughed at when he was trying to be actually funny. This allowed Monstrox to persuade him to turn to evil in order to take revenge on his former mockers. After stealing one of Merlok's magic staffs and getting his magic library scattered across the wilds of Knighton, Jestro is guided by Monstrox to retrieve the other books that contain his power. Despite giving in to the Book's pressure and being exposed to the Book of Evil and gaining a monstrous appearance, Jestro harbors doubts about his villainous role before learning he was intended to become Monstrox's new body once he regained his full power. In the season 2 finale, Jestro reforms completely and helps the Nexo Knights save Clay, reverting to his original appearance upon Monstrox's apparent destruction. But in season 3, while making failed attempts to make amends to no avail, Jestro encounters the Cloud of Monstrox who uses his special evil lightning to control Jestro into helping him again. He reforms again after being freed from the Cloud of Monstrox' evil lightning and assists Roberto Arnoldi into cleaning up the shattered Colossus of Ultimate Destruction.

text: Monstrox (voiced by Mark Oliver) - The true main antagonist of the series. Monstrox was an evil arch-necromancer and former member of the Wizards' Council who terrorized Knighton with his monster armies and the Forbidden Powers a century ago prior to the events of the series until Merlok used his all his magic in a potent spell. In addition, he turned Wizards' Council member Wanda Moorington into Ruina Stoneheart. The spell turned Monstrox into a sentient book of dark magic known as the Book of Monsters, containing the essence of his monster army that can be summoned from his pages. Merlok also divided Monstrox's corruptive power among in eleven spellbooks: The Book of Evil, The Book of Chaos, The Book of Fear, The Book of Anger, The Book of Deception, The Book of Destruction, The Book of Revenge, The Book of Greed, The Book of Envy, The Book of Cruelty, and The Book of Betrayal. Out of pride, Merlok did not destroy the books and housed them in his library to study them. At the start of the series, Monstrox is found by Jestro, concealing his true identity while persuading the jester to turn evil to aid him in regaining the books after Merlok sacrificed himself to scatter them across Knighton. In "The Fortrex and the Furious" after Jestro turned on him, Monstrox's true identity is revealed along with his need to possess a host body to regain human form. Monstrox originally intended to possess Jestro, but he decides to use Clay instead in "Kingdom of Heroes" where part of the ritual had Monstrox regurgitating the eleven spellbooks. Though Clay uses the Merlok 2.0-augmented Techcaliber to destroy the Book of Monsters, Monstrox survived and became a cloud-like being called the Cloud of Monstrox. Monstrox uses his lightning to corrupt Jestro again to aid him alongside the Stone Monster Army to retrieve both the cover of his old book body and his staff. Afterwards, the Cloud of Monstrox leads Jestro and the Stone Monster Army into obtaining tablets containing the Forbidden Powers and place them into pillars at the top of Mount Thunderstrox to awaken the Colossus of Ultimate Destruction to destroy Knighton. In "Between a Rock and a Hard Place," the Cloud of Monstrox successfully awakens the Colossus of Ultimate Destruction in possesses it. In "The Fall," the Cloud of Monstrox guides the Colossus of Ultimate Destruction to Knightonia in order to destroy it. Clay turns it into glass where it shattered with the Cloud of Monstrox still in it. A glowing fragment that presumably has Monstrox' essence in it was claimed by Ruina Stoneheart.

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.
NOTE: Other movie projects are parodies of other franchises. Such as "Lanceformers", an obvious reference to Transformers. And another called "Knightjago 3", a parody of Lego Ninjago: Masters of Spinjitzu. Another reference to Ninjago is when a movie extra is seen wearing a mask of Lord Garmadon, a major antagonist and later supporting character of the show.

The two then rescued Clay, who was chained on a target, getting spun around all the time.

Near the end, King Halbert apologizes to Macy, and he proclaims her an official NEXO Knight. Lance then gets Dennis back on one condition: Lance has to be Dennis' servant once a week.

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.

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. King Halbert seemed like he didn't want to say the tournament was over. Suddenly, 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 Jestro 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, and Jorah tried to argue that it was no fair, since everyone saw that his knights were superior, but the Tighty Knighties explain that they're good in shows and sports, but when it comes to fighting monsters, they can't compete. So 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. In the credits, with the regular music, Tightwad is heard screaming and yelling that he doesn't want to kiss Hamletta again.

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, and Lance doesn't seem to have any visible symptoms, though he does say that his hair lost his luster. The Book of Monsters, on the other hand, 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.

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.

October 22, 2016 (2016-10-22)
0.61[17]

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.
Error: The Book of Revenge is often called the Book of Vengeance.

Recapping from the previous episode, the Nexo Knights arrive to assist Lance and return to their duties as knights. However, now that Jestro and the Cloud of Monstrox have the Staff of Monstrox, they head to the Iron Mountains where the Cloud of Monstrox awakens a Rogul that held a tablet containing the Forbidden Power of Relentless Rust (which rusts any metal that it touches). During the Stone Monster Army's attack on Armourville, the Rogul starts rusting every statue it comes in contact with while the Cloud of Monstrox reanimates the statues there. The Knights arrive, but their armour and the Fortrex's treads are rusted by the Rogul and Jestro, with Clay's hand briefly turning to stone when he gets blasted by the Forbidden Power, and then crashes into a statue just as Monstrox zaps it. Luckily, Merlok has devised a way for the Nexo Knights to combine Nexo Powers, a strategy which makes them powerful enough to destroy the stone monsters and send them into the Cloud of Monstrux. After the retreat of Jestro and Monstrux, Robin gives the Nexo Knights new armour meant to be resistant to all of the Forbidden Powers. During a solo training session, while his cohorts are celebrating their victory, Clay privately confides to Merlok that his fighting skills seem to be deteriorating. When Merlok scans him, he realizes Clay has been cursed with dark, ancient magic and advises not to tell the others.

Meanwhile in the Badlands, Jestro and the Cloud of Monstrox meet King Halbert's former sculpture Roberto Arnoldi where he works to carve Stone Garden Gnomes to help build the Stone Monster Army. Merlok 2.0 explained that he defeated Monstrox, and when he got defeated, he dropped the Forbidden Powers. Merlok tried to destroy them, but they were too powerful. So, he sealed the Forbidden Powers away in stone tablets, and creating Roguls to protect them. Upon Jestro emptying the Forbidden Power of Relentless Rust into one of the pillars on top of Mount Thunderstrox, the Cloud of Monsters helps Jestro into telling some of the Gargoyles to remain behind to guard it.

During the battle, Merlok 2.0 has a hard time deciding on a combo to give to three of the Nexo Knights causing the group to move fast enough to keep the Cloud of Monstrox from reanimating them. They even trick the rust-inducing Rogul into striking the Evil Mobile since it has some metal features in it. Upon Jestro, the Cloud of Monstrox, Roberto, and the Stone Monster Army getting away, the Nexo Knights capture one of the Stone Garden Gnomes in order to figure out how the Cloud of Monstrox's lightning works. Clay tells Merlok 2.0 that his "illness" is getting worse and that a replacement must be found before the final parts of it occur.

Out of fear, King Halbert puts the museum on lock down, binding the museum in an indestructible metal plating which keeps the Cloud of Monstrox and the Stone Monster Army out, but leaves the Nexo Knights, King Halbert, Queen Halbert, and Edward Evanston trapped inside with the sculptures and Rogul with no way to acquire Nexo Powers. The Rogul of Relentless Rust attempts to rust the metal. However, at the same time, Ava hacks the security measures to shut down the lock down leaving only the stone walls to keep the building standing. After Jestro is given the Forbidden Power of Collapsing Crumble, he uses it to literally bring down the house and escape with the Forbidden Power of Collapsing Crumble. Luckily, everyone makes it out the museum alive, but half of Clay's body has already petrified. Meanwhile, Jestro and the Cloud of Monstrox add the Forbidden Power of Collapsing Crumble to the pillars on Mount Thunderstrox while Clay continues to give advice to his unseen successor.

Jestro and the Cloud of Monstrox lead the Stone Monster Army to the town of Burningham to find the Rogul that is associated with the Forbidden Power of Blazing Burn (which gives the user the ability to create and hurl deadly fireballs). To the Cloud of Monstrox's surprise, the inhabitants are all members of the Lava Monster Army who were left without a job after the destruction of their former base and found the Rogul, gaining hope that they could build a town around it. General Magmar is the mayor, Lavaria is a yoga teacher, Whiparella is a street artist, Bookkeeper is a glockenspiel performer, and Flama and Moltor work at the Hot Rock Cafe. The Cloud of Monstrox' attempt to get Sparks and Burnzie to give him the Rogul fails when General Magmar identifies him and doesn't want to work for him again. Upon being blown out of the village by Whiparella and telling this to Jestro, the Cloud of Monstrox asks why he didn't use his evil lightning on them. The Cloud of Monstrox stated that he didn't think it would be needed. When the Nexo Knights find out about this, they go to Burningham. The Lava Monsters, who have become pacifists as payment for their crimes, are taught how to fight again to protect their town from the Stone Monster Army. Aaron trained Whiparella by calling her names that weren't her name. Roberto Arnoldi sculpts a flying part of the mobile headquarters for Jestro and the Cloud of Monstrox to use upon being inspired by the two of them calling each other an airhead. Although Jestro seems to have succeeded in stealing the Rogul, it was actually Beast Master being used as a decoy as Beast Master escapes. The real Rogul was taken to the Fortrex so that the Nexo Knights could study what makes the Forbidden Powers tick. Ava figures that the information that Merlok 2.0 is looking for is in the Knighton Castle Library. As Clay and Merlok 2.0 continue to talk to the unidentified successor, the Lava Monsters are shown celebrating their victory as they begin to spar with one another.

Jestro and the Cloud of Monstrox animate the Stone Monster witch Ruina Stoneheart who they use to help the Harpies capture Queen Halbert during her visit to Hammerin. Despite resistance from Macy and the Mayor of Hammerin, Ruina and the Harpies succeed in their mission to capture Queen Halbert. Upon hearing word of this, King Halbert gives Macy a much needed gift, a dragon-like vehicle designed by Robin known as "Hotspur." The Nexo Knights attempt to save Queen Halbert, but it turns out to be a diversion and the Stone Monster Army steals the Rogul containing the Forbidden Power of Blazing Burn and Techcalibur from the Fortrex while also dealing serious damage to it. Axl, Aaron, and Lance go after Jestro and the Rogul while Macy and Clay continue in chasing after Ruina. Unfortunately, the Stone Monster Army escapes with the reanimated Rogul and the Forbidden Power of Blazing Burn. Although Queen Halbert is successfully rescued, Clay's transformation into stone has finally been completed.

The Forbidden Power of Blazing Burn is transferred into another one of the pillars atop Mount Thunderstrox. Drawing power from the four Forbidden Powers they collected, the Cloud of Monstrox grows to massive proportions and reveals why they are collecting Forbidden Powers. The pillars happen to be atop the head of the now-petrified Colossus of Ultimate Destruction which will awaken and lay waste to Knighton once all 10 Forbidden Powers are collected. Back in the Fortrex, Clay's successor is revealed to be Aaron who will lead the Nexo Knights until a cure for Clay has been found. The Nexo Knights find the Stone Monster Army attempting to attack the city of Knighton. King Halbert, Queen Halbert, the Royal Guards, Sir Bricklyn, and the students at the Knights Academy work to defend Knighton from the Stone Monster Army. The Cloud of Monstrox plans to use his augmented lightning to fry every server in the Knighton Library Tower, thus wiping Merlok 2.0 (and therefore the Nexo Powers and all of his memories) out of existence. At the same time, Roberto Arnold works on carving something on a stone tablet. As the Nexo Knight approach Knighton, they fight their way passed the reanimated Grimrocs with the help of Dennis and Robot Hoodlum's Merry Mechs. The Nexo Knights arrive where they find King Halbert fighting the reanimated giant statues of the previous Knighton kings. At the s. Robin uses the Minitrex to link Merlok 2.0 to the servers so they can download the backup for his memories before the Cloud of Monstrox erases it. Unfortunately, while Merlok 2.0 is providing Aaron's battle suit with a Combo Power to defeat the Cloud of Monstrox, a bolt from the Cloud of Monstrox seemingly destroys him, but Aaron uses the Combo Power to send the Cloud of Monstrox back into his harmless book body. The Stone Monster Army returns to Mount Thunderstrox, believing themselves to be victorious. It is soon revealed that the Minitrex kept Merlok 2.0 alive and intact. Ava works to rebuild Merlok 2.0' systems in order to get him operational again. During this time, Robin in the Black Knight mech soon uncovers a carving on a stone tablet dropped by Roberto Arnoldi during the fight which describes the Cloud of Monstrox's plan to awaken the Colossus of Ultimate Destruction.

Despite the Nexo Knights' victory in the previous episode, the entire kingdom is in depression. Lance gains the idea to throw a party in honour of Clay saving Queen Halbert in order to lighten everyone's moods. However, Clay's petrified body is painted and placed in his remote-controlled battle suit in order to avoid suspicion. Meanwhile, Robin and Ava have to deal with Sir Bricklyn and his colleague Sir Grimace when they take some students from the Knighton Academy on a tour of the Fortrex (and constantly prank them) for the school field trip. Jestro gains the idea to ambush the Fortrex in hopes of cheering up the Cloud of Monstrox unaware that the knights are at the party. Fortunately, Ava is able to restore Merlok 2.0 to the Fortrex and he is able to provide the Knighton Academy students with a Nexo power that allows them to fight back against the Stone Monster Army, forcing them to retreat (as they do not have the Cloud of Monstrox to reanimate them) much to the Cloud of Monstrox's amusement. Back at the party, Macy loses control Clay's battle suit forcing the Nexo Knights to pin it down. After the party, they reveal the truth about Clay to King and Queen Halbert and they agree not to mention it to the rest of the kingdom.

Although he does tell Robin to start working on a "Secret Project" and advises him not to tell the others. Elsewhere, Jestro and the Cloud of Monstrox get their hands on the Rogul associated with the Forbidden Power of Shocking Scare (which temporarily eliminates all courage in the victim, rendering them too cowardly to fight back).

Clay has seemingly turned evil again and has wiped out the Nexo Knights. Fortunately, this news broadcast was falsified in order to deceive Jestro and the Cloud of Monstrox. However, in order to get Clay to infiltrate them, he goes through spy training under the teachings of Jack Shields (a parody of James Bond). Clay, posing as his villainous self, infiltrates Jestro and the Cloud of Monstrox's forces. He finds out their plans to collect the Forbidden Powers. As Clay shakes Ruina Stoneheart's hand, a surge of energy passes through them. Unfortunately when Robin's life is put on the line, Clay's cover is blown, but the other Nexo Knights swiftly launch an ambush on the Stone Monster Army, forcing them to retreat.

After his rage sabotages an interrogation attempt, Clay leaves the team to meditate until he can control his rage. Elsewhere, Jestro and the Cloud of Monstrox have gotten their hands on the Forbidden Power of Devious Demolition (which causes parts of its targets to fall off). This Forbidden Power enables the Cloud of Monstrox to bring the debris created by it to life in order to overwhelm the Nexo Knights. When an avalanche disables the Nexo Power transmitter, the Nexo Knights are forced to retreat to the top of a mountain where they meet up with Merlok's old friend, magician/demolitions expert "The Great Rockowski" who has devoted his life to pacifism until the Stone Monster Army destroy his topiary. After Rockowski forces the Stone Monster Army to retreat, the Nexo Power transmitter is repaired. Meanwhile, the Forbidden Power of Devious Demolition is transferred into another pillar atop Mount Thunderstrox. While Clay is meditating, he sees Ruina invade his mind causing him to become even more violent, vengeful, and more than willing to send the entire Stone Monster Army, Jestro, and the Cloud of Monstrox to their graves.

After obtaining the Rogul that is associated with the Forbidden Power of Metal-Morphosis (which possesses the ability to turn gold into lead), Jestro and the Cloud of Monstrox buy and reanimate the petrified Lord Krakenskull, his Krakenbeast, and his army who were unearthed by Jorah Tightwad. When Lord Krakenskull uses his amalgamated Forbidden Power of Petrified Quake (which allows his Krakenbeast to generate earthquakes and petrify objects with a roar), it petrifies the Nexo Knights vehicles causing the Knights to retreat. When they regroup even with a combo Nexo Power, Lord Krakenskull's army proves to be indestructible until Clay arrives, destroys the Forbidden Power of Petrified Quake enough to undo everything it had ever done, and unleashes a violent frenzy which is only halted when Ruina slows him down. Clay rejoins the Nexo Knights, although Ruina's plans are furthering into motion. After the Stone Monster Army retreats, they begin to head to Mt. Thunderstrox. Before that happens, Jestro uses the Power of Metal-Morphosis on Jorah Tightwad's gold city and coins.

Although they succeed in transferring the first two into the pillars atop Mount Thunderstrox, the Nexo Knights track them as they are headed to transfer the last one. Clay goes into another frenzy and destroys the Rogul associated with Forbidden Power of Confounding Confusion, only to attempt to kill Ruina who reveals that she is Clay's mother and cursed Clay in hopes that he would follow in her footsteps. Returning to the Fortrex, Merlok 2.0 confirms that Ruina was telling the truth and that Clay possesses magical abilities that could even surpass his own. Realizing that his rage can no longer be controlled, Clay uses his newfound magic to give Macy a Nexo Power that forces her to return him to his inanimate state, much to Macy's misery.

Recapping from the previous episode, Merlok 2.0 reveals that Ruina was not only Clay's mother, but also Merlok's sister and fellow magic user and Wizard's Council member Wanda Moorington, who was originally pure-hearted until Monstrox's presence corrupted her, forcing Merlok to petrify her. As he is also Clay's uncle, Merlok become Clay's parental guardian while refraining from telling Clay about his inherent powers due to fear that he would end up like Ruina. Elsewhere, Jestro and the Cloud of Monstrox have obtained the final and most powerful Forbidden Power known as the Forbiiden Power of Awesome Annihilation (which can reduce an entire town to ruins with a single explosive blast). After adapting to the combinations of their vehicles and battle suits, the Nexo Knights attempt to prevent the Stone Monster Army from transferring the last Forbidden Power into Mount Thunderstrox. Alas, the Forbidden Power of Awesome Annihilation is transferred into the last pillar atop Mount Thunderstrox and through the process of a lengthy and powerful electrical storm that started as a result, Mount Thunderstrox is destroyed as the Stone Colossus of Ultimate Destruction awakens from within it. When the process is complete, the Cloud of Monstrox enters and possesses the Colossus of Ultimate Destruction and immediately relieves Jestro and Roberto of their duties, believing their usefulness has expired and that he no longer needs to take orders from them. As the Colossus of Ultimate Destruction marches towards a nearby town, Aaron is unsure how to defeat it. Back in the Fortrex, Clay's petrified body begins cracking as an unnatural blue glow is emitted from it.

The Nexo Knights try to lure him onto a bridge where they intend to destroy so that he will fall into the chasm below and buying them time for Robin to finish his "Secret Secret Project". However, in order for the project to be complete, Merlok 2.0 must be transferred into the Knighton library. Meanwhile in the Fortrex, Clay's consciousness remains intact in his petrified body and he uses his magic to destroy his stone body and return to human form. Now once more the just and benevolent hero he used to be, Clay assists Robin with the project. However, the Colossus of Ultimate Destruction is able to escape the chasm while swallowing Axl whole in the process.

After the village of Suburbington is destroyed, Axl manages to escape from the Colossus of Ultimate Destruction's bowels through the digestive system, much to his discomfort. The Nexo Knights then proceed to the Knigton library, where Merlok 2.0 is transferred to and Robin's "Secret Secret Project" is completed and revealed to be an escape rocket. Macy, Lance, Aaron and Axl are dropped onto the Colossus of Ultimate Destruction's head, but their attempts at weakening the Colossus of Ultimate Destruction prove futile until Clay and Merlok 2.0 (whose consciousness was downloaded into a robotic body dubbed "Mechlok") join the battle. Clay uses his magic to create a combo power that turns the Colossus into glass and he technopathically manipulates the Fortrex to strike the Colossus of Ultimate Destruction in the heel, resulting in the entire Colossus crumbling to pieces, killing Monstrox, petrifying the entire Stone Monster Army, and returning Jestro to his normal form. The Nexo Knights celebrate at Knighton Castle and Clay becomes determined to find his mother. Meanwhile, Jestro and Roberto are cleaning up the remains of the Colossus of Ultimate Destruction. Having avoided petrification, Ruina manages to steal one lone glowing fragment of the Colossus of Ultimate Destruction for her upcoming plans.
