|The Great Devourer|
|First Appearance||The Rise of the Great Devourer|
9450 Epic Dragon Battle
The Great Devourer was a monstrous snake 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 as one and found the four silver Fangblades. She was also responsible for Lord Garmadon's transformation to evil, as she bit him as a child, corrupting him with her evil venom. Some time after this, the Serpentine tried using the Devourer to scare the people of Ninjago underground in a bid 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, the Anacondrai began scheming to awaken the Devourer by uniting the Serpentine and finding the Fangblades. Following a series of battles with the Ninja, the Fangblades were obtained and Pythor unleashed the Devourer from The Lost City of Ouroboros, after which she consumed Wu and Pythor before heading into Ninjago City to wreak havoc. The Ninja battled the Great Devourer, which proved to be a dangerous adversary, until Garmadon offered to destroy the beast by combining the Golden Weapons. Reluctantly, the Ninja gave him the weapons, and Garmadon killed the beast.
Despite all, the demise of the Devourer would only create further conflicts. The Devourer's venom revived the Stone Army and Krux used eggs from the beast to breed an army of Vermillion warriors. Needless to say, the massive serpent had a tremendous influence on the future of Ninjago.
In its early days, the Devourer was just a small green viper. She was then (possibly) corrupted by an evil darkness, turning her venom into an ominous poison that could turn the purest of hearts evil. She bit a young Master Garmadon, infecting him with darkness, and began to grow into a titanic monstrosity. The ancient Serpentine somehow took control of the Devourer and used her in their initial invasion of Ninjago—following the Serpentine's defeat, the beast was sealed under The Lost City of Ouroboros.
The Great Devourer's existence was revealed when Cole and Zane entered the Constrictai Tomb. While searching for the inhabitants, the two Ninja discovered a crude mural on the wall depicting the Serpentine gathering before an especially massive snake. Zane translated the drawings as a prophecy: when the Serpentine united as one, they could find the Four Silver Fangblades and unleash the Great Devourer, who would consume all of Ninjago and turn day into night.
The Great Devourer made its first true appearance in a flashback Master Wu had before he set out to find Lord Garmadon's Dimension, when the old man told his students how Lord Garmadon's descent into evil began when he was bitten by a strange green snake in the bushes. Wu explained that the snake—a young Great Devourer—was a legendary beast that would consume all in her path, and her venom could turn even the most noble soul into a being of pure evil. He charged the Ninja with finding the four Fangblades before the Serpentine could, as the Fangblades were the keys to the Devourer's revival.
Despite the Ninjas' best efforts, Pythor managed to collect all of the Fangblades and retreat to Ouroboros, where the Devourer was thought to have been imprisoned. Placing the Fangblades in the teeth of the statue overlooking the Slither Pit arena, Pythor commanded the Devourer to awaken, expecting her to emerge from the statue. To his surprise, the beast was not within the statue, but beneath the arena itself, and she was far larger than Pythor had expected.
More frightening still for the Anacondrai General, Master Wu revealed that the Great Devourer was not bound to obey the one who awakened her—in fact, she had no qualms about eating the Serpentine along with the rest of the world. As Master Wu prevented Pythor from fleeing, the Great Devourer burst free of her stone prison, immediately swallowing Pythor and Master Wu whole.
The Ninja attempted to escape the Devourer in the Destiny's Bounty, but they only succeeded in making the beast even bigger when it ate their jettisoned ballast and the ship itself. However, the escape gave them time to reach Ed & Edna's Scrap N Junk, where they used a Tornado of Creation to build the Ultra Sonic Raider. Equipping their new vehicle with Zane's recording of the Sacred Flute, they managed to deal some damage to the Devourer, also discovering a small weak spot on the top of its head. However, the Great Devourer destroyed the Ultra Sonic Raider's sonic cannons and withdrew to attack Ninjago City.
The Ninja followed the Great Devourer and managed to prevent it from consuming any innocent civilians, but the monstrous snake proved too powerful for them to defeat. Even the arrival of Nya's Samurai Mech and the Ultra Dragon did little against the Devourer. Eventually, Lord Garmadon arrived and revealed that the only way to slay the Devourer was to use the power of all four Golden Weapons, which only he could do. Despite their misgivings, the Ninja agreed, with Kai also telling Lord Garmadon about the Devourer's weak spot.
While Lord Garmadon left to prepare his attack, the Ninja distracted the Great Devourer, leading it on a mad chase around the city. Eventually, they were able to immobilize the beast by tangling its body in buildings and tricking it into biting its own tail, leaving its weak spot wide open as Lord Garmadon combined the energies of the Golden Weapons with his own dark powers. Declaring his actions as vengeance against the Great Devourer for dragging him down the path of evil, Lord Garmadon leaped from a skyscraper and plunged through the creature's weak spot, causing the Great Devourer to explode spectacularly, releasing large amounts of venom onto the city.
Despite its destruction, the Great Devourer's evil influence continued to plague Ninjago—literally, as its defeat flooded the city with venom. The Ninja spent a large amount of time helping the city's cleanup efforts. When Skales was attempting to assert his leadership over the Serpentine, Skalidor suggested unleashing the Great Devourer again, only for Skales to strike the Constrictai General for the bad idea.
Lord Garmadon called his Serpentine forces together on the Black Bounty for a brainstorming session on how to defeat the Ninja with his new Mega Weapon. Upon hearing that the weapon could only create, not destroy, Lasha suggested recreating the Great Devourer. Lord Garmadon was not amused by the idea, and had the Venomari Scout thrown overboard as a sign of his displeasure.
The Great Devourer's venom dripped onto several pieces of Stone Army merchandise at the Ninjago Museum of History, bringing them to life. Later, some more venom dripped on the Giant Stone Warrior exhibit found by Misako, bringing the ancient soldier to life.
More of the Devourer's venom seeped deep underground, activating an entire army of Stone Warriors, which were suddenly awoken, sealed in a hidden tomb unearthed by the Serpentine—although this also ended with the Serpentine themselves being sealed away once again.
As the Digital Overlord searches Wu's memories, the rise of the Great Devourer can be seen.
An ancient Serpentine legend revealed that the Serpentine were, in the beginning, trying to save the people of Ninjago from the Golden Master, and tried to use the Great Devourer to scare the people of Ninjago underground. However, the people defeated the Devourer and believed that the Serpentine were the enemy, and drove them underground.
Later in the episode, it is revealed that Pythor survived his time in the Great Devourer's stomach, although the experience turned his scales white.
Master Chen kept a scale of the Great Devourer in his Hall of Fame.
The Great Devourer had an insatiable appetite and the ability to consume anything that it came across. Whenever it consumed something, it grew larger and more powerful—the Ninja noticed that it would have been truly unstoppable if allowed to consume the bustling metropolis of Ninjago City.
In combat, the Great Devourer normally used its tremendous size and nigh-invulnerability to its advantage, attempting to swallow anything in its path and smashing opponents with its spiked tail. Its venom was capable of bringing inanimate objects to life and could corrupt even the purest individuals into wrathful megalomaniacs against their will, such as the case of Garmadon.
Additionally, it seemed to display a sense of tactical thought, tricking both the Ninja and the Ultra Dragon into thinking they had either defeated or escaped it, only to suddenly ambush them when their guard was lowered. Despite its massive size, it was also incredibly fast and had the ability to burrow through the ground with ease.
The Great Devourer only displayed two real weaknesses over the course of the show. Like the Serpentine, it appears to be intolerant of the Sacred Flute's music, to the point of physical pain. It also had a small weak spot on top of its head—if it took a particularly powerful blow to this point, it would result in its death, as evidenced when Garmadon used the Golden Weapons to finally destroy it once and for all.
- The Great Devourer has only appeared in one LEGO set, 9450 Epic Dragon Battle. Physically, it bears more resemblance to the young Devourer seen in Master Wu's flashback in "Tick Tock," and it is significantly smaller than the Devourer seen in the show—in fact, it appears to be approximately the size of the statue in Ouroboros' Slither Pit.
- In one of the supplementary Ninjago comics, it is implied that The Overlord was responsible for creating the Great Devourer by corrupting a snake with darkness, thus the Overlord might be responsible for turning Garmadon evil in the first place. This theory is supported by the end of "Rise of the Spinjitzu Master": when Lloyd defeats the Overlord, Lord Garmadon is purified of the Devourer's venom.
- The Ninja immobilize the Great Devourer by tricking it into biting its own tail. This is another reference to ouroboros—often depicted as a snake eating its own tail—the concept of cyclical events and entities.
- The Devourer is one of the three most powerful and largest beings of Ninjago, the others being The Overlord (the most powerful) and The Preeminent (the largest).
- The Great Devourer's true relationship to the Serpentine is unknown. It was considered a ruler and god of the Serpentine, but they immediately hid in fear of it when it was released, as they were avoiding the considerable threat of being eaten.
- According to Kai, the four Silver Fangblades were made from the original teeth of the Great Devourer.
- The Great Devourer's abilities and traits appear to be larger-scale versions of the Serpentine's tribal abilities. It has the Constrictai's rapid burrowing abilities, the Anacondrai's ability to swallow things whole, and the effects of its venom could be interpreted as a mixture of Hypnobrai Hypnotism and the Fangpyre's Bite.
- Physically, the Devourer's green skin and tendency to secrete mass amounts of fluorescent green venom hearken back to the Venomari, but its long fangs resemble the Fangpyre and its pink eyes are similar to the Anacondrai.
- The Great Devourer is apparently female, as it laid Vermillion eggs sometime after the Serpentine War. These eggs were later obtained by Krux, who used them to breed his army.
