Having freed Lloyd from the Digital Overlord, the Ninja learn of something in Ouroboros under the codename Arcturus. The five must head out to stop this new threat.
This episode provides examples of:
- Call-Back: The Ninja and Garmadon reference the events of "Wrong Place, Wrong Time", where the Golden Weapons were shot into space. This turns out to be the Overlord's plan—without Lloyd's powers to steal, the Golden Weapons are the only remaining source of Golden Power in the realm, so he's building a rocket to retrieve them.
- Cliffhanger: The Ninja stow away on the Nindroids' rocket, launching off into space in hopes of stopping them from stealing the Golden Weapons.
- Elemental Powers: The Ninja get their elemental powers back, albeit at the cost of permanently downgrading Lloyd's Golden Power into Energy.
