Great Devourer

The Great Devourer was a monstrous serpent with a mutation,[1] worshipped by the Serpentine as a god, believed to consume all of creation if left unchecked. According to legend, she could only be unleashed if the Serpentine tribes united and found the four silver Fangblades. She was responsible for Lord Garmadon's transformation to evil, as she bit him as a child and corrupted him with her venom. The Serpentine then tried using the Devourer to scare the people of Ninjago underground to protect them from the Golden Master. However, this only fueled the people's disgust for the Serpentine. Around this point, the Devourer was sealed underground. When Lloyd freed Pythor, he schemed to awaken the Devourer by uniting the Serpentine and finding the Fangblades. Pythor successfully did so at the Lost City of Ouroboros, where the Devourer consumed him and Wu before heading to wreak havoc in Ninjago City. The ninja battled the Devourer until Garmadon seized the Golden Weapons and vaporized the beast. Despite all, the Devourer's demise would only create further conflicts. Her venom revived the Stone Army, her eggs were used by Krux to breed an army of Vermillion, and the destruction her caused during her rampage through Ninjago City would ultimately motivate Harumi to become the Quiet One after the beast was responsible for both of her parents' deaths. Needless to say, the massive serpent had a tremendous influence on the future of Ninjago and would be responsible for many of the future enemies faced by the ninja.
