They led the Anacondrai and the Serpentine into battle, thus starting the First Serpentine War when they heard from Chen and Clouse the humans are planning to attack them. When the Elemental Alliance defeated the Serpentine and banished them into tombs, the Anacondrai generals were banished to the Cursed Realm by Garmadon.
After Chen started the Second Serpentine War, Garmadon knew the only way to stop them was to unleash the spirits of the Anacondrai generals by sacrificing himself into the Cursed Realm. Once completed, the generals were freed and began helping the people by cursing Chen's imposter Anacondrai Army.
After this was done the generals thanked both Pythor for finally making them proud by restoring him to his size and give their gratitude to Garmadon's son Lloyd for helping his father free them and for doing what they never could do: uniting the Serpentine and humans as one before departing to the Departed Realm to be at peace.
- In "Spellbound," six Anacondrai generals, including Arcturus, were banished to the Cursed Realm. However, when Garmadon is banished in order to free the generals, there are seven of them that emerge from the portal. It is possible that one general was banished earlier or later than the others or it could be just an error.
- None of the generals, except for Arcturus seem to be present in any flashbacks during the war and only appear before their banishment, implying that the other generals didn't fight in the war itself. The reason for this is unknown.
