Codename: Arcturus is the sixth episode of the third season of LEGO Ninjago: Masters of Spinjitzu.


In the ocean's depths, Pythor leads the Nindroids in attaching balloons to the Overlord's preserved body, allowing them to raise the Nindroid MechDragon. With their leader secure, Pythor, General Cryptor, and the Nindroids take off towards The Lost City of Ouroboros.

At The Temple of Light, Lloyd gives up his Golden Power to restore the Ninjas' Elemental Powers. Later, at Borg Tower, Master Wu spots General Cryptor aboard a train heading for Ouroborus. He tries to send Jay and Cole to investigate, but they are fighting over Nya once more at the movie theater. Wu sends Kai instead, but the Red Ninja has become overconfident with the heroes' previous victory over the Overlord. As a result, he is attacked by Nindroids, and Pythor himself grabs him, tapes his mouth, and takes him prisoner.

Cole, Jay, Zane, and Lloyd discover the secret of Arcturus and head for Ouroboros. When they arrive, the floor opens, revealing the OverBorg's ultimate creation, Codename: Arcturus—a rocket designed to reach Delta V, the comet that contains the lost Golden Weapons.

The Ninja release Kai and secretly board the rocket, preparing to go somewhere they never expected: space!



  • The Golden Weapons were last seen in "Wrong Place, Wrong Time," where they were believed to have been destroyed after being used against the Mega Weapon. This episode reveals that the weapons survived the event and went into outer space: Contrary to popular belief, the weapons actually landed on a comet called Delta V, not a star named Arcturus. The reason as to why they named the project, Arcturus, and it's connection to the celestial zodiac mentioned in the episode, is currently unknown.
  • In this episode, Lloyd is first seen with the Techno Silver Armor, but in "The Titanium Ninja," he is seen for a brief second in his original Techno Robe.
  • The Hageman  brothers had a cameo appearance in the theater. This marks the first time they appear in the series.
  • As of this episode, the four original ninja finally have their elemental powers fully restored thanks to Lloyd.
  • While pursuing the Nindroid convoy, Kai says "I love it when a plan comes together," a line associated with the character John "Hannibal" Smith from the 1980s TV series "The A-Team."
  • The way the Ninjas' allies shine Cole and Jay's elemental symbols in the sky to summon them is a reference to the Bat-Signal used to summon Batman.
