Sensei Garmadon

Sensei Garmadon is a major character in LEGO Ninjago: Masters of Spinjitzu. He is the first son of the First Spinjitzu Master, the older brother of Sensei Wu and husband to Misako.

Prior to the beginning of the series, a young Garmadon was bitten by the Great Devourer and infected with evil. The corruption transformed him into Lord Garmadon, a power-hungry villain who served as the main antagonist of the first two seasons of the series. After a battle with his younger brother, Garmadon was trapped in the Underworld, where he gained command of the Skulkin. During the pilot episodes of the series, he sent the Skulkin to retrieve the Golden Weapons in order to grant him incredible power.

In the first full season of the series, Garmadon is revealed to have a son, Lloyd Garmadon, who seeks to follow in his footsteps. Lord Garmadon actually becomes something of an ally to the Ninja after Lloyd unleashes the Serpentine on Ninjago, working with his old foes to both save his son and to remove a potential rival for conquest of the land. Despite seeing their alliance through to the end, Lord Garmadon continues to seek means of gaining the advantage over the Ninja, eventually finding himself with a perfect opening to steal the Golden Weapons.

In the second season, Lord Garmadon once again becomes the main villain of the series, using the power of the Golden Weapons to take leadership over the remaining Serpentine. Combining the weapons into a single Mega Weapon, he schemes to remake Ninjago in his own dark image. Later on, he allies with the Overlord and gains control of the Stone Army, only to be betrayed by the former and used as a vessel for the original evil's rebirth.

After the Overlord's defeat at the hands of Lloyd, Garmadon is completely purified of evil, and happily reunites with his family at last. He has since joined his brother Wu as a mentor to the Ninja, hoping to atone for his dark deeds by helping them overcome whatever new evils may arise to threaten Ninjago.
