LEGO Ninjago: March of the Oni

When an unknown criminal syndicate threatens the Royal Family, the Ninja are called back into action and must protect the royal princess and a fabled artifact that may hold supernatural powers.

In the wake of a vicious attack upon the palace, the Sons of Garmadon steal the second Oni Mask, and the ninja invite the royal princess, Harumi, into their makeshift family.

While Princess Harumi adjusts to life with the ninja, Lloyd and Jay search for answers about the Oni Masks, while Cole and Zane attempt to infiltrate the Sons of Garmadon.

Undercover Zane is brought back to the Sons of Garmadon's secret base where he meets Killow, an enormous biker whom Zane assumes to be the gang's leader. He is mistaken and learns the true leader is a mysterious unseen villain known only as the Quiet One. As Zane attempts to discover the Quiet One's identity, Cole cools his heels in a dank cell.

Zane's near demise at the hands of Mr. E forces the ninja to flee aboard the Bounty, where they discover that a transmission Zane intercepted may reveal the hidden location of the Quiet One.

During the crash, the ninja are separated. Harumi and Lloyd land in one part of the jungle, while the remaining ninja, aboard the Bounty, crash several miles away. As the Sons of Garmadon close in on them, a desperate three-way race for the third Oni mask ensues. Aboard the Bounty, the ninja make an unexpected discovery. The baby Cole rescued has become a toddler overnight.

The discovery of the Quiet One's identity leads to a flashback that reveals a pivotal moment in Harumi's childhood and the reason for her hatred of the ninja. In a tragic moment, her biological parents are killed in an attack by the Great Devourer (ref. Season 2), a loss for which she blames the ninja. Back in the present, Lloyd and Harumi make their way deeper into the Oni Temple.

Lloyd awakens to find himself Harumi's prisoner. He is transported back to the ruined Royal Palace of Secrets where Harumi intends to fulfill her sinister plan and use the Oni masks to resurrect Lord Garmadon. Unbeknownst to Harumi, the ninja have managed to tame the crustacean and ride the beast back to NINJAGO City, where they appeal to the Commissioner for help. The Commissioner rallies

Thinking they have prevented the resurrection of Garmadon, the ninja enjoy a long overdue celebration at Laughy's Bar (all but Lloyd, who is unable to celebrate in the aftermath of Harumi's betrayal). The celebration is short-lived, however, when a newscast reveals an unknown assailant with four arms has broken Harumi out of NINJAGO City's central jail!

The ninja retrieve a battered and broken Lloyd and rush him to Mystake's Tea Shop, where Mystake brews up a magical tea to heal his wounds. Unfortunately, the tea comes with a price. It will heal Lloyd's injuries but will cost him his elemental powers. The ninja have no choice but to agree. As Lloyd recuperates, Garmadon's powers grow and he raises an enormous Colossi
