List of Nexo Knights characters

The Nexo Knights are the defenders of Knighton. The Nexo Knights fight the forces of Jestro and Monstrox.^[1][2] Among the members of the Nexo Knights are:

• Clay Moorington^[3] (voiced by Giles Panton)^[4] – Clay Moorington is the leader of the Nexo Knights. Clay is no-nonsense and lives by the Knight's Code, dedicated to being the best knight he can (having dreamed of it since being a young orphan). His strictly regimented style occasionally causes him to clash with his fellow knights, particularly the more laid back Lance. His armor is blue and his crest shows a falcon and his signature weapon is a Claymore, which has the ability to supercharge into the "Sword of Strength".^[1][2] 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.^[5] Starting in "A Little Rusty," Clay is affected by the Cloud of Monstrox's dark magic, which slowly transforms him to stone.^[6] The transformation is completed in "Rock Bottom", with Aaron covering for Clay until he can be restored.^[7] In "The Gray Knight", Clay is reanimated by the Cloud of Monstrox and used to try and destroy the other knights.^[8] In "Heart of Stone", it is revealed that Ruina is Clay's mother and Merlok's sister, making Clay the nephew of Merlok.^[9] Later on, Clay regains his human form and heroic mindset and helps to battle the Colossus of Ultimate Destruction.^[10][11]
• Princess Macy Halbert^[3] (voiced by Erin Mathews)^[12] – Princess Macy Halbert is one of the Nexo Knights, and is the only female in the team. Her parents are King and Queen Halbert, but 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. In "Rock Bottom," Macy starts using a dragon-shaped vehicle named "Hotspur" that can fly, shoot fireballs, and combine with her battle suit.^{[7][13][14][11]}
• Lancelot "Lance" Richmond (voiced by Ian Hanlin)^[15] – Lance Richmond is a Nexo Knight who does not 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 Horse/Turbo Jouster, 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 was forced to become a knight by his parents when he was young.^[16] Starting "A Little Rusty," Lance drives the Twin Jouster, which can detach its back half to increase its speed.^{[6][17][18][11]}
• Aaron Fox^[3] (voiced by Alessandro Juliani)^[19] – Aaron Fox is one of the Nexo Knights who enjoys thrills. His armor is green and his crest is a fox, and he employs a Blazer Bow as his main weapon. Aaron enjoys employing his knight shield as a hover board, and often attacks from the air. Aside from his shield, his main choice of transportation is a crossbow-shaped fighter jet called the Bow Flyer. 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.^[20] After "In Charge", Aaron drives a new vehicle called the Rock Climber.^[21][22][11]
• Axl^[3] (voiced by Brian Drummond)^[23] – Axl is the largest of the Nexo Knights. He 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 is equipped with twin drills and can transform into an aerial vehicle.^[24][11]

• Merlok 2.0 (voiced by Brian Drummond)^[25] – A digital wizard who helps the Knights defeat evil by sending them Nexo Powers. Merlok was originally a normal wizard who was the last wizard in the kingdom of Knighton and a member of the Wizards' Council. He had a sister named Wanda Moorington, who was also on the Wizards' Council before being turned evil by Monstrox and becoming Ruina. Due to Wanda being Merlok's sister, this makes Merlok the uncle of Clay, which he initially refused to tell Clay. When Jestro first allied with the Book of Monsters, Merlok used his magic to drive them out of the capital city, but was inadvertently absorbed into the castle's computers. In "The Fall," Merlok 2.0 downloads his form into a robot body dubbed Mechlok.^[26][27]
• Robin Underwood (voiced by Erin Mathews)^[28] – Robin wants to become a Nexo Knight and is a first-year student at the Knights' Academy. His crest shows a chicken and he often employs the Fortrex's weapons during battles with the Lava Monster Army. Robin is known as the master mechanic who built the battle suits and more.^[29]
• Ava Prentis (voiced by Maryke Hendrikse)^[30] – 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.^[31]
• King Halbert (voiced by Brian Drummond)^[32] – 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 is not 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 RV into their Fortrex base. King Halbert also commands a large humanoid mech when the need arises for him to go into battle.^[33]
• Queen Halbert (voiced by Nicole Oliver)^[34] – 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.^[35][36]
• Hamletta – Lance's pet domestic pig. Lance initially encountered Hamletta while being held hostage by the Lava Monster Army and adopted her after escaping.^[37]

• Robots – The Kingdom of Knighton is home to a number of robots who serve various tasks such as helping defend the kingdom or providing the knights with training partners.
  • Squirebots – The helpful robots who fight to defend the kingdom.
    • Dennis – A Lancebot who is Lance's personal attendant, having taken care of Lance since he was a baby. Dennis quit working for Lance in "The Book of Total Badness,"^[37] but returned on the condition that Lance serves him once a week.^[41] In "Storm Over Rock Wood," Dennis quits working for Lance to join Robot Hoodlum's Merry Mechs.^[42]
    • Claybot – The Squirebot of Clay who wields a claymore. The Claybots can oil swords and sharpen the boots.^[43]
    • Macybot – 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.
    • Aaronbot – The Squirebot for Aaron who is dedicated to Aaron's safety. The Aaronbot can help calculate risk and assert dangerous situations.
    • Axlbot – A Squirebot who serves Axl in going back and forth from the kitchen to get Axl's food. It tends to have a bad sense of direction.
    • Deputybots - Squirebot cowboys employed by Jorah Tightwad that live in the west, specifically in the town of Nothing Hill.

• Sir Swordmore Brickland (voiced by Michael Adamthwaite) – The principal of the Knights Academy.^[45]
• Jorah Tightwad (voiced by Brian Drummond) – A wealthy "gold factory" owner who is somewhat full of himself. He obtained the Book of Envy when Merlok scattered the Books of Power across the kingdom, making him desire everything. 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. He has a Scottish accent.
  • Lotta Fun & Lotta Budget (voiced by Caitlyn Bairstow) – Tightwad's twin Squirebot assistants. Their personalities reflect their names with Lotta Fun being perky and upbeat, while Lotta Budget is more grumpy and money focused.
  • 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.
    • Shia LaBlade (voiced by Ian Hanlin) – The Tighty Knighties' counterpart of Clay who wields a double-bladed sword. His name is a reference to Shia LaBeouf.
    • Jousting Bieber (voiced by Vincent Tong) – The Tighty Knighties' counterpart of Lance. His name is a reference to Justin Bieber.^[46]

• Monstrox (voiced by Mark Oliver)^[49] – The main antagonist of the series. Monstrox was a 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. Merlok transformed 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 into 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.^[1][2] 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 aid him in regaining the books. After Jestro turns on him, Monstrox's true identity is revealed along with his need to possess a host body to regain a physical form. Monstrox originally intends to possess Jestro, but he decides to use Clay instead. After Clay destroys the Book of Monsters, Monstrox survives as a cloud-like being called the Cloud of Monstrox. The Cloud of Monstrox leads Jestro and the Stone Monster Army into awakening the Colossus of Ultimate Destruction to destroy Knighton. The Cloud of Monstrox possesses the Colossus, only to be destroyed by Clay.^[26][50][11]
• Jestro (voiced by Vincent Tong)^[51][52] – Jestro was once the king's court jester, and was mocked due to his clumsiness. This allowed Monstrox to persuade him to turn to evil in order to take revenge on his former mockers.^[1][2] 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. In third season, Jestro encounters the Cloud of Monstrox, who uses his lightning to control Jestro into helping him again, giving him an electrifying appearance and turning him even crazier than his original corruption. He reforms again after being freed from Monstrox's lightning.^{[26][53][54][55][11]}
• Roberto Arnoldi (voiced by Vincent Tong) – Roberto Arnoldi is a sculptor who used to work for King Halbert and takes things very literally. One day, he was commissioned to make a "smashing" statue of Queen Halbert. When he literally made a smashing statue of Queen Halbert hammering Scurriers and Globlins, Queen Halbert was pleased while King Halbert was displeased. After King Halbert fired him and kicked him out of Knightonia, Arnoldi settled in the Badlands near Mount Thunderstrox, where he sold Stone Garden Gnomes to make money. After meeting Jestro and the Cloud of Monstrox, Arnoldi sided with them in order to get revenge on Knightonia. After the Colossus of Ultimate Destruction is destroyed, Arnoldi and Jestro were seen cleaning up its remains.^[26]

In the book series, she is described as being a talkative and excitable young knight who is not a fan of all the media attention that comes with being a Richmond.^[21]

Originally appearing as a main character in the "Knights' Academy" spin-off books series, Fletcher made his mainline debut in "Weekend at Halbert's", where he is shown visiting the Fortex as part of a Knights Academy student field trip. In the book series, Fletcher is shown to be a bit clueless in regards to his knight training, while subsequently demonstrating a talent for sorcery.^[21] It was to be revealed later on that he is the son of Ruina Stoneheart and Clay's younger brother, left by his mother before she succumbed to evil.
