Crystalized is the fifteenth and final season of the computer-animated Ninjago television series (titled Ninjago: Masters of Spinjitzu before the eleventh season). The series was created by Michael Hegner and Tommy Andreasen. The season aired in two parts: the first in May 2022, and the other from September to October 2022. Following the passing of Kirby Morrow, the season is the first in the series to feature Andrew Francis as the new voice actor of Cole. Although Crystalized marks the conclusion of the original Ninjago series, it is not the final installment of the Ninjago franchise, as a new series for the Lego Ninjago brand is set to premiere in 2023.
