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.

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.

• Queen Halbert (voiced by Nicole Oliver) – The Queen of Knighton, King Halbert's wife, and Macy's mother.

  • 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.
  • The Tighty Knighties – Tightwad's servants who serve as his counterparts of the Nexo Knights.

In "Storm Over Rock Wood," the Cloud of Monstrox once used his evil lightning on Robot Hoodlum so that he can steal their shields.

Villains

• Monstrox (voiced by Mark Oliver) – The 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 and 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.

• Jestro (voiced by Vincent Tong) – Jestro was once the king's court jester, and was constantly laughed at due to his clumsiness and not laughed at when he was trying to actually be 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.

• 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 some Scurriers and Globlins, Queen Halbert was pleased while King Halbert was displeased. After King Halbert fired him and kicked him out of Knightonia, Roberto settled in the Badlands near Mount Thunderstrox where he sold Stone Garden Gnomes that he carved in order to make money for himself. Upon meeting Jestro and the Cloud of Monstrox, Roberto sided with them in order to get revenge on Knightonia where he started by making versions of Stone Garden Gnomes that have pointy heads. Roberto later made a new mobile headquarters for Jestro and the Cloud of Monstrox after the Evil Mobile was accidentally rusted by the Rogul that was associated with the Forbidden Power of Relentless Rust. During the attack on Burningham, Roberto has sculpted a flying part of the mobile headquarters that was animated by the Cloud of Monstrox' lightning. Upon the Stone Colossus of Ultimate Destruction being reanimated, Roberto Arnoldi and Jestro are relieved of the Cloud of Monstrox's servitude. Following the Stone Colossus of Ultimate Destruction being turned to glass and shattering, Roberto Arnoldi and Jestro were seen cleaning up its remains.
