Ninjago: Season 6

With the defeat of Morro’s ghost invasion, the ninja have now become huge media celebrities. But dark forces once more threaten NINJAGO Island as the Teapot of Tyrahn is rediscovered by the ghost of Clouse, Master Chen’s former right-hand man. He allows Nadakhan, an evil Djinn (Genie), and captain of the infamous Misfortune’s Keep, to escape the teapot. After reassembling his pirate crew, Nadakhan returns to his home realm and kingdom of Djinjago, to find it collapsing. This destruction, caused by the ninja defeating the Preeminent, leads Nadakhan to vow revenge. He refits his ship so it can fly and prepares to attack. Now they are Sky Pirates.
