Descriction Description

Jestro is not bad. He is just no good at being good. Or funny for that matter. He was King Halbert’s jester and every day people laughed at him. Except for when he actually tried to be funny, then they fell silent. One day Jestro had enough and he seized the opportunity to become so powerful that no-one would ever dare laugh at him again.


Jestro tried to be a wizard, then a knight before finally becoming the jester of King Halbert's court. As the king's jester, he would always ruin his own performances which caused him to be the laughingstock of Knighton . He would also be upset with his attention being stolen by Merlok the Magician. He found a friend in Clay Moorington, who would later become his enemy.

Season 1

Embarrassed by being a laughingstock with the citizens of Knighton, combined with his jealousy of Merlok, Jestro turned to evil and decided to wreak havoc with the Book of Monsters; who he found in Merlok's library. He was persuaded by the book to become a "bad boy", in order to finally be taken seriously among his peers. They worked together to summon a Lava Monster Army. ("The Book of Monsters - Part 1")

The army, commanded by Jestro, then executed many attacks, though the Nexo Knights showed up to save the day every time. ("The Book of Monsters - Part 2", "Alliance of the Fortrex", "Jestro the Bad... The Really, Really Bad")

Season 3
