On season 4 the Ninja are split due to Zane's sacrifice, But are reunited by Lloyd. The ninja participate in "The Tournament of Elements" hosted by Master Chen when they get the news that Zane is alive. They participate in the tournament with 12 other masters Skylor Chen (the Orange Ninja Wizard Sorceress Mage Magician and Master/Mistress of Amber and Absorption), Griffin Turner (Wizard Sorcerer Mage Magician and Master of Speed), Paleman also known as Mr. Pale (Wizard Sorcerer Mage Magician and Master of Light), Chamille (Wizard Sorceress Mage Magician and Master/Mistress of Form), Ash (Wizard Sorcerer Mage Magician and Master of Smoke), Bolobo (Wizard Sorcerer Mage Magician and Master of Nature and Plants), Gravis (Wizard Sorcerer Mage Magician and Master of Gravity), Neuro (Wizard Sorcerer Mage Magician and Master of Mind), Tox (Wizard Sorceress Mage Magician and Master/Mistress of Poison Toxic Acid and Venom), Shade also known as Shadow (Wizard Sorcerer Mage Magician and Master of Shadow), Karlof (Wizard Sorcerer Mage and Magician Master of Metal) & Jacob Pevsner (Wizard Sorcerer Mage and Magician Master of Sound and Music). In the Tournament Kai falls in love with Skylor Chen, & becomes Karlof's enemy (as they fight constantly in Episode 36 & 37). After many battles all the masters start to realize that when someone loses Chen uses his staff of elements to suck their powers for a transformation spell, which is performed by Clouse (Chen's number 2, Master of Dark Magic Dark Arts and a Wizard Sorcerer Mage and Magician). The spell makes everybody with the Andacondrai mark become Fake Andacondrai. The Andacondrai mark spot people include Chen himself, Clouse, Garmadon (who was revealed to be Chen's student), Skylor Chen (who was revealed to be Chen's daughter and spy), & every other Andacondrai wannabes. The transformation was not complete, and to complete it they'll need the saliva of a true Andacondrai (which was tiny Pythor in jail). When they took Pythor and complete the transformation, on the other hand, every elemental master has discovered all their elemental dragons. They fight all the Andacondrai wannabes. And the Andacondrai wannabes are sucked into the cursed realm, which leads to Garmadon sacrificing himself to be sucked into the cursed realm so he can unleash the Andacondrai spirits to curse Chen's army. At the end of season 4 Morro (Wizard Sorcerer Mage and Magician Master of Wind and Air and Sensei Wu's First Student and Pupil) is accidentally freed from the Cursed Realm.
