“A snake of rather unusual size is attacking Ninjago! If you are watching this now, please leave the city at once!”

The attack of the Great Devourer[1] is an event when the Great Devourer was unleashed on Ninjago City.



After Pythor unleashed the Great Devourer using the Four Silver Fangblades at the Lost City of Ouroboros, the Great Devourer awakened and swallowed Master Wu and Pythor and then chased and destroyed the Destiny's Bounty, causing the ninja to retreat.

Attack on Ed & Edna's Scrap N Junk

After the ninja lured the Great Devourer to Ed & Edna's Scrap N Junk while they were at a fare in Ninjago City and made the Ultra Sonic Raider out of the Tornado of Creation and used a recording of the Wu's flute to hurt the Great Devourer although the serpent escaped and damaged Zane.

Attack on Ninjago City

The ninja rushed to Ninjago City where the Great Devourer started attacking the people and hitting the buildings, one of these buildings being the apartments that Harumi and her parents lived in.

Later, when Nya flew her Samurai Mech into the mouth of the Great Devourer, The Ultra Dragon swooped in and began attacking the Great Devourer, but the serpent hit the Ultra Dragon to the ground and hurt him. While the ninja grieved, Lord Garmadon returned and told the ninja that the only way to destroy the Great Devourer was with the Golden Weapons which only Garmadon could wield, the ninja made the decision to give Garmadon the weapons while they made the Great Devourer stay in place.

After successfully making the Great Devourer stay in place, the ninja watched as Garmadon jumped down of the building and stabbed the Devourer with the Golden Weapons, killing the serpent.

  • This event caused Harumi to begin plotting against the ninja.
  • This event also caused the Stone Army to be reawakened from their deep slumber after thousands of years.
  • Although Pythor was responsible for releasing the Great Devourer, the general population never found out, as they saw only the large serpent destroying the city and did not know what had happened in Ouroboros.[2]
