The Anacondrai warriors or the Anacondrai Cult were a cult led by the notorious Master Chen who worshiped the Anacondrai tribe. Following his banishment to a secluded island, Chen began building up his criminal empire, which consisted of an army of Anacondrai worshipers.

The warriors' primary goal was to steal the powers of the Elemental Masters, which they would use to perform a spell and transform into Anacondrai. Despite their success in doing so, they needed the essence of a true Anacondrai to complete the spell; otherwise, they would return back to their human forms. The warriors captured Pythor, the last surviving Anacondrai, and used his sweat to complete the spell, officially becoming fake Anacondrai.

The warriors invaded Ninjago and staged a final battle against the Elemental Masters and their allies at the Corridor of Elders. As the battle waged on, Chen's former pupil, Garmadon, sacrificed himself, freeing the spirits of the Anacondrai generals which cursed the Anacondrai warriors and banished them to the Cursed Realm. Several months later, when The Preeminent—the physical manifestation of the Cursed Realm—was released into Stiix, Nya unlocked her True Potential and drowned the colossal beast. Incidentally, the Cursed Realm was destroyed and all those inside of it were killed, including Chen, and were sent to the Departed Realm. The sole survivor, Clouse, escaped the realm and went on to free a deceptive djinn; these events were later undone. Master Yang's magic later enabled Chen, Zugu, and Eyezor to return from the Departed Realm, but they were soon dispatched there once again by the ninja.
