List of Nexo Knights characters

Nexo Knights

• ' – 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. 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". 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's dark magic which slowly transforms him to stone, causing him to look for a successor. 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", Clay returns to the side of good. However, 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 Ruina. In "Heart of Stone", it is revealed that Ruina is Clay's mother and Merlok's sister making Clay the biological maternal nephew of Merlok. Clay has incredible magical powers, and is re-petrified in order to stop him from hurting anyone. Later on, he regains his human form and heroic mindset, and helps to battle the Colossus of Ultimate Destruction.
• ' – 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. However, in "Rock Bottom," Macy starts using a dragon-shaped vehicle named "Hotspur" that can fly, shoot fireballs, and combine with her battle suit.
• ' – Lance Richmond is one of the Nexo Knights 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 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 became a knight because his parents forced him to become one during his childhood instead of becoming a celebrity. Starting "A Little Rusty," Lance drives the Twin Jouster that can detach its back half to become faster.
• ' – 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. After "In Charge", Aaron drives a new vehicle called the Rock Climber.
• – 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 has large twin drills up front and can transform into an aerial vehicle.

  Supporting characters

• ' – 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. Due to Wanda being Merlok's sister, this makes Merlok the uncle of Clay which he refrained from telling upon gaining custody of him since he wanted to tell him when 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 robot body that is dubbed Mechlok.
• ' – 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.
• ' – 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.
• ' – 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.
• ' – 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.
• ' – 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".

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.
• * ' – 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.
• * ' – 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.

• ' – 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.

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.
