 * The evil in Garmadon completely takes over him, and it mainly manifests itself in the form of overwhelming greed. He returns to the Monastery of Spinjitzu to steal the Golden Weapons in an attempt to recreate Ninjago in his own image. Wu confronts him, and after a short battle, the combination of the four weapons and the protection spell on their kimonos opens a gateway to the Underworld, where Garmadon is struck down to. As he fully succumbs to the evil in his veins, Garmadon battles Samukai (leader of the Skulkin) for command over the Skulkin army, and easily wins (becoming the ruler of the Underworld). Wu realizes that Garmadon will stop at nothing to get the Golden Weapons, so he hides them away in secret locations, each guarded by a Dragon. Wu then makes a map of the four secret locations, and gave the map to a trustworthy friend to keep.

When he disagrees, the Skulkin take him to a Lighthouse Prison guarded by a Leviathan, to force him to design their vehicles. After he successfully complies with their demands, the Skulkin do not release him from the prison, and leave him there.
 * 5 years before the events of Rise of the Snakes:

Encouraged by compassion for his sister, Kai agrees to train in the art of Spinjitzu under Wu's teaching to become a ninja.

Rise of the Snakes (Season 1)

 * Lloyd gets kicked out of Darkley's Boarding School after spending his whole life there and makes his journey to Jamanakai Village, in an effort to become like his father. He terrorizes the village, but is soon suppressed by the Ninja.

 * Lloyd returns to Jamanakai Village with the entire Hypnobrai tribe. The tribe uses hypnotism to take control over the citizens.

 * Zane finds a Falcon after another evening of feeling left out from the Ninjas' antics, and he follows the Falcon to a Treehouse being constructed by Lloyd and the Serpentine. He informs the Ninja of his discovery, and they begin their mission to destroy it. Just before they finish the destruction, Skales uses the previous post-hypnotic command on Cole to attack the Ninja. As the Ninja struggle to fight Cole, Master Wu and Nya arrive on Kai's dragon, using a flute (later to be described as one of the flutes of the First Spinjitzu Master used to banish the Serpentine in tombs) to snap Cole out of his trance. The group hurry back to the unguarded Monastery, only to find that the Hypnobrai had burned it down in search for their staff. Cole, Jay, and Kai blame Zane for the loss of their home, and in the ruckus, no one notices Zane flying off on his dragon. Later on, the Ninja try to make the best of their situation, but immediately regret what they had said to Zane. To their surprise, Zane returns, conveying to them that he had not been hurt by what they had said, but merely had seen and followed the Falcon again. He then leads them to where he had followed the falcon to: an abandoned ship in the middle of the Sea of Sand, that would be their new home, and goes by the name "Destiny's Bounty."

With a bit of help from Jay's father, Jay activates the Bounty 's new flying function that allows them to escape the approaching Fangpyre, but the staff falls over board in the process.
