Harumi

Harumi, also known as the Jade Princess and The Quiet One is the leader of the Sons of Garmadon and former right hand to Emperor Garmadon. She is the main antagonist of Sons of Garmadon, and a major antagonist in Hunted and Crystalized.

When Harumi was young, her parents would be killed during the attack on Ninjago City by the Great Devourer. She was later adopted by the Emperor and Empress of Ninjago, but she began to hate the Ninja for what they had done, and admired Lord Garmadon. In her young teens, she founded the group the Sons of Garmadon, hell-bent on resurrecting the Dark Lord. Her plan was a success, and she ruled with an iron fist as the right hand to the now Emperor Garmadon. She would later be killed after Garmadon showed his wrath on the city.
