Tournament of Elements

Tournament of Elements is the fourth season of the Ninjago: Masters of Spinjitzu series. It was originally released on February 25th, 2015. Kai is the focus character for this season and Master Chen is the main antagonist. The Anacondrai Cultists serve as the villainous faction.

It is the second installment in the Master Trials arc. It focuses on Kai and his journey to learn that power isn't what makes someone special, and to accept himself. This season features a special minifigure variant of Kai featured in the TV show, that being Powered Kai. This version of Kai does not appear as a physical minifigure. The collectible weapons this season are the Jade Blades.

In March 2015, a non-canon prequel of Season 4 was released titled Shadow of Ronin. While it is non-canon, it provides the context that the Ninja knew the character Ronin before the events of Season 5 and establish that Ronin was the one that kidnapped Zane and P.I.X.A.L. and delivered them to Chen.

In July 2015, a series of five shorts were released as a prequel to Season 4 showing Chen's life on his island before the tournament.

It is preceded by Rebooted and followed by Possession.

Plot Summary
After the loss of Zane, the team is split apart, and Lloyd seeks to rebuild it. But everything changes when they find out that Zane is alive, and that crime lord, Master Chen, invites the ninja and the other Elemental Masters to a Tournament, so that he can steal their powers in order to complete a spell that will turn him and his worshippers into Anacondrai.

A non-canon video game prequel to Season 4 featuring the Ninja's first encounter with the mercenary known as Ronin. The events of this game are made to explain what happened to Zane before Season 4.

Chen mini movies
A collection of non-canon shorts that show what Chen was up to before the events of this season. All of the episodes bog down to him just futzing around with his chair.

Continuity

 * This is the first time we are shown other Elemental Masters besides the Ninja.
 * Chen mentions that he knows the truth of what happened to Kai and Nya's parents. It's implied that he was just lying to Kai in order to gain his trust, but this does foreshadow the sinister truth behind their disappearances when Kai and Nya were young.
 * Morro appears at the very end of the season, having escaped through the portal that Garmadon opened up to banish Chen and his army.
 * Pythor returns again in this season, having been shrunk by the Nano Pill Cyrus Borg developed during Rebooted. He is grown up again by the end of this season and plots his return.
 * The Stone Samurai Warrior that the Ninja defeated in The Stone is seen incarcerated at Kryptarium Prison.
 * In flashbacks of the Serpentine War, Kai and Nya's parents Ray and Maya are shown using their respective Elemental Powers, Fire and Water. This was meant to foreshadow Nya inheriting her mother's Elemental Power in the following season.
 * The beginning of the season shows Lloyd running through a simulated gauntlet trying to retrieve the Golden Armor. This establishes that the Golden Armor was retrieved after the Golden Master was defeated and has been secured at an unknown location.
