Ninjago: Sons of Garmadon

Sons of Garmadon is the eighth season of the animated television series Ninjago: Masters of Spinjitzu (titled Ninjago from the eleventh season onward). The series was created by Michael Hegner and Tommy Andreasen. The season aired from 16 April to 25 May 2018, following the seventh season titled Hands of Time. It is succeeded by the ninth season titled Hunted.

The eighth season was the first season to be produced following the release of the 2017 film The Lego Ninjago Movie, which had significant impact on its development. The season adopted the new character designs from the movie, including face and hair alterations for the main ninja characters that differed significantly from the previous seasons. This was a particularly controversial move for existing fans of the show. The central character Lloyd Garmadon was given a new voice actor Sam Vincent, replacing Jillian Michaels.

The season introduces the character Princess Harumi as the season's main antagonist, who is revealed to be the leader of a criminal biker gang called the Sons of Garmadon. The storyline follows Harumi's plan to steal three Oni masks in order to resurrect Lord Garmadon in purely evil form as the season's overarching antagonist. The season also begins the Oni Trilogy story arc which would be continued in the next two seasons, Hunted and March of the Oni.
