NINJAGO | S2E13 | Rise of the Spinjitzu Master

As the Overlord transfers to Ninjago, the Ninja, together with an injured Lloyd, are guided by the robotic Falcon to the Temple of Light. Once there, they find an ancient mech that the First Spinjitzu Master used to fight the Overlord. With the arrival of the Ultra-Dragon, the group flies back to Ninjago City and find the city possessed and the Overlord atop a dark tower, morphed into his true Dragon-like form. The Ninja fight the Stone Army, but the ancient mech is destroyed by Nya and they are forced to fight on the ground. But they are saved by Dareth, who uses the Helmet of Shadows and gains control of the Army, sending them against the Overlord. Lloyd and the Ninja climb the tower, with Cole and Jay being infected by the Overlord with Darkness. Lloyd is forced to go on alone as Zane fights the two infected Ninja and Kai fights his still-enslaved sister. Facing the Overlord, Lloyd summons the Golden Dragon and his armor becomes golden, denoting that he has become the next true Spinjitzu Master. Lloyd and Dragon Overlord fight, with the Overlord saying that he can never be defeated, as Light is always balanced with Darkness. Lloyd finally allows himself to be consumed by the Overlord and unleashes a strong burst of inner light, dispersing the Overlord and purging his wicked Shadow from Ninjago and all its inhabitants (including Nya, Cole, Jay, and Zane). As the group gathers together again, Lloyd mourns the loss of his father, only to see him emerging from the rubble, purged of both the Overlord's Darkness and the Great Devourer's venom. As Lloyd, Garmadon and Misako have a private family reunion, the four Ninja vow that even with the Overlord defeated, at last, they will continue to protect Ninjago. The Ninjas and Nya come together, along with Garmadon's family. The episode ends with Sensei Wu and Kai looking at the sun rising above the liberated city.
