Lord Garmadon

Lord Garmadon is the main villain of the LEGO theme "Ninjago". He is the brother of Sensei Wu, who turned evil and tried to take over the world of Ninjago, but was killed by Wu. He somehow became the ruler of the underworld when he went there, and returned in command of an army of skeleton people, including the actual ruler of the underworld, Samukai. Garmadon's goal is to possess the four golden weapons of Ninjago.

In the Ninjago movie, Garmadon is betrayed by Samukai, but the skeleton is destroyed when he tries to possess the four weapons, and a portal to another dimension is opened, which Garmadon intentionally lets himself to be sucked into so he can become strong enough to wield the four weapons from inside. In the upcoming 2012 sets, he returns from the void, now with four arms and with a new group of snake people.
