Sons of Garmadon

The Sons of Garmadon (also known as the S.O.G.) is a villainous biker organization that serves as the main antagonististic faction in the eighth season of the same name, Sons of Garmadon. The group is led by the Quiet One, Harumi, and seeks to conquer Ninjago and resurrect Lord Garmadon—the Ninjas' former adversary who continuously tried to destroy Ninjago. To bring about his rebirth, the group searches for the three Oni Masks.

Following the group's attempt to resurrect Garmadon at the Temple of Resurrection, the Sons of Garmadon were arrested by the Ninjago police force and were sent to Kryptarium Prison for their crimes. However, Lord Garmadon, though incomplete, was successfully reborn and ultimately broke Harumi and the Sons of Garmadon out of prison. After Lord Garmadon defeated Lloyd in a fight, the Sons of Garmadon then planned to return to Ninjago City and show the world who their new emperor was—Emperor Garmadon. They soon went on while Garmadon creates a being called Colossi, which terrorizes Ninjago.

The Ninja attempt to stop it, but failed, resulting in the Destiny's Bounty destroyed and Kai, Jay, Zane, Cole and Toddler Wu being presumed dead, but unbeknownst to anyone, they used Traveler's Tea to escape to the Realm of Oni and Dragons.
