Garmadon

Garmadon is an enemy of the Ninja and one of the main antagonists of LEGO Ninjago. He is the main antagonist of the Pilot Episodes, Legacy of the Green Ninja, and Hunted, the main protagonist of March of the Oni and Garmadon.

Garmadon is older brother of Wu and son to the First Spinjitzu Master. At a young age he was bit by the Great Devourer and the Oni blood inside him began to fester. He was blinded by evil and sought to steal the four Golden Weapons of Spinjitzu from Wu to use for evil. He first appears as an adversary to the Ninja, as he sends his Skulkin Army after them to retrieve their weapons and return from the Underworld. His plan is a success, and he manages to leave the Underworld through a portal to the Realm of Madness, which lets him grow four arms to possess the weapons. He returns later to create the Mega Weapon and destroy the Ninja, but he is tricked by the Overlord and his body is used for his revival. In Sons of Garmadon he is resurrected from the dead and becomes Emperor Garmadon and rules over Ninjago City in Hunted. In Season 10 he helps the Ninja against the Oni threat, and leaves them to follow a journey of his own. He returns in Crystalized to help his son achieve his Oni form and defeat the Overlord once and for all.

He is the current Elemental Master of Destruction, and a master of Spinjitzu and Forbidden Spinjitzu.
