He and Monstrox then summoned the Lava Monster Army and Stone Monster Army into the Kingdom of Knighton to destroy the Nexo Knights. Clay, one of said knights, was actually a friend of his, who tried to encourage and help him before his unsuccessful performance that caused a power outage. Jestro is the supporting protagonist, he is the good jester. He is helping with the Nexo Knights. Descriptions This is a description taken from Do not modify it. (visit this item's product page)

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.



  • His name is a pun on "jester".
  • His appearance is similar to The Joker and Harley Quinn from DC Comics.
  • He shares some resemblance to Krazi from Ninjago.
  • It has been observed that Jestro's toy figure looks a bit different than his appearances in promo videos so far, as the figure has his Jester cap's flairs drooping in the traditional fashion, while in the videos, they are pointed upwards to resemble horns.
  • He has the same voice actor as Kai which is Vincent Tong.
