LEGO Ninjago[]
Crystalized[]
When the Ninjas' old enemy, Harumi, survived thanks to the mysterious Crystal King, Harumi built Mister F with the goal of helping the Crystal King take over Ninjago and destroy the Ninjas. When Lloyd arrived at the location of the Crystal King's Council, he mistook him for Mr. E, until Pythor explained that he was a new model of Mr. E, who unfortunately still did not speak. And when Lloyd was revealed, he and the other council members attacked and captured him. Shortly after the other council members stole the golden weapons of Spinjitzu, they turned them into the weapons of Destruction and then brought the Crystal King, who was indeed the surviving Overlord, to Ninjago. And when Lloyd managed to escape, he and the others tried to stop him and prevent him from escaping, but Lloyd escaped and took Harumi with him. Soon, he and the others began an attack on Ninjago, infecting the ground and other people with dark crystals. And when some Ninjas with some friends were hiding in a newspaper warehouse near the harbor and a radio message was sent to the other Ninjas, he managed to intercept it, and he relayed it to the Overlord, after which he and the others began to search the warehouse and destroy it, but the Overlord wanted him and the others to leave the Ninjas to him. And when he and the other members of the Overlord's Council began to fight the Ninjas, he encountered Zane, who had gained Dragon Form and was using it to fight him. During the fight, Zane took one of the crystalized Ice Shuriken and restored it by channeling his energy into it, after which Zane knocked over the sign he was left under, and it was uncertain if he remained intact or was destroyed.
