Lego Ninjago (stylized as NINJAGO) Masters of Spinjitzu is a current line of sets produced by Lego. It uses elements from the previous Ninja series. There are several changes from the previous series. These include the removal of the Shogun and Bandits, and the introduction of the Skeleton Army and the Serpentine. Also noticeable is the inclusion of vehicles which imply a more modern setting than the feudal Japan setting of the previous incarnation.
