Season 1: Rise of the Snakes
Season 3: Rebooted
Season 2 of LEGO Ninjago: Masters of Spinjitzu, subtitled Legacy of the Green Ninja, was preceded by Season 1, and succeeded by Season 3. Lloyd was the focus ninja and mascot, and Lord Garmadon was the main antagonist until Episode 20, in which The Overlord took over as the main antagonist; the Serpentine were the villainous faction of the season until Episode 20. During Episode 21, the Stone Army took over as the villainous faction of the season.
With the Golden Weapons now in Lord Garmadon's possession, the Ninja begin training Lloyd so that he can face his father one day and save Ninjago, something which he was afraid to for the sake of their bond. Garmadon works to thwart the prophecy by recruiting the masterless Serpentine and merging the Golden Weapons into the powerful Mega Weapon. After Garmadon's last attempt ended with Lloyd aging to a teenager like his four mentors, he attempts to change the events of the past. The original four Ninja follow Garmadon and use the Golden Weapons of the past to destroy the Mega Weapon, restoring the timeline and sending the Golden Weapons into space.
While Garmadon ends up on an island with a disembodied voice called the Overlord, the venom of the Great Devourer seeps into catacombs beneath Ninjago and animates the Stone Army, trapping the Serpentine underground in the process. Along with Misako, Lloyd's mother, the Ninja travel to the Dark Island to stop Garmadon. The Ninja fail to stop the countdown to the final battle, and the Overlord is revealed to be the dark lord from the prophecy. He possesses Garmadon and heads to Ninjago, with the Ninja in tow. After they found a way out of the Island, Lloyd uses his newfound Golden Power to defeat the Overlord, purge Garmadon of his evil, and become the Golden Ninja.
