But the Great Devourer proved to be beyond anyone's control, swallowing Pythor and Sensei Wu alive, the former suffering side effects from exposure to the serpent's stomach acid, and running rampant on Ninjago with the Ninja unable to subdue it. However, in the end, the Ninja manage to lure the Devourer into a trap during its siege of Ninjago City, allowing Lord Garmadon to destroy the Great Devourer with the power of the Golden Weapons in revenge for the grief and madness it caused to him. Despite its death, the monster's venom still seeps into Ninjago City's sewage system, eventually reawakening the Stone Army.

While his tribe were sealed away, the Anacondrai Tribe had no food source and ultimately fell to starvation and cannibalism with Pythor the sole survivor. Upon being released, Pythor pretended to be Lloyd's ally to steal the map to the Serpentine tombs to release the Constrictai and the Venomari Tribes. Soon after finding the lost city of Ouroborus, through deceit and an alliance with Skales, Pythor becomes the first Snake King of all Serpentine. It becomes clear soon that Pythor had been driven insane by his imprisonment and his hatred of the surface dwellers, using the allegiance of the tribes to unleash the Great Devourer to exact revenge on people of Ninjago for locking up the Serpentine underground. As the series progressed, Pythor has finally managed to collect all four Silver Fang Blades, despite the oppression from the Ninja, Lord Garmadon, and the Skeleton Army, realizing too late that the Great Devourer would consume everything in its path, including himself alongside Sensei Wu.
