Spinjitzu Masters was a Ninjago theme introduced in 2018 that included 5 spinners of the main characters. The Spinjitzu Masters outfits are very similar to the Airjitzu suits, but represent when the ninja are actually performing the art of Spinjitzu. The Spinjitzu Masters spinner sets include 70633 Kai, 70634 Nya, 70635 Jay, 70636 Zane and 70637 Cole—for ninja vs. ninja skill showdowns.
LEGO Ninjago, also known as Ninjago: Masters of Spinjitzu, theme was introduced in 2011 and included sets that are based off of original storylines, a TV series and The LEGO Ninjago Movie, a movie based on the theme. The main premise of the Ninjago universe is based around six teenage Ninja, Kai, Jay, Cole, Zane, Nya, and Lloyd, who have been trained by their master Sensei Wu, fighting forces of evil to protect the land of Ninjago.
