Description: time portal to stop Ninja origin While training Lloyd, the Ninja find out that the Serpentine have returned to the Lost City of Ouroboros and are preparing their vehicles for an all-out assault. The Ninja, together with Lloyd (who has now begun to harness his immense potential), attack and begin to defeat the Serpentine, with Lloyd freezing Garmadon's Mega-weapon. Retreating, Garmadon comes up with a master plan; he will travel back in time and make sure the Ninja are never brought together, changing history in his favor. As he escapes through the time-portal he wishes into existence, the Ninja follow him. They arrive on the very day Nya was kidnapped and Kai was recruited by Sensei Wu. As he leaves the 4-Weapons shop, the Ninja take Wu aside and tell him what is at stake, so that when the Skeletons arrive, history apparently starts repeating itself. But Garmadon, disguised as a Skeleton, makes sure Nya's kidnapping fails and the Ninja are forced to take matters into their own hands to make sure history runs its course, going as far as kidnapping Nya and handing her over to the Skeletons. But Garmadon joins forces with his past self and goes to the Fire Temple, resting place of the Sword of Fire, and prepares to defeat Kai. The Ninja from the present arrive and fight back, before realizing that the only way to heal the damage done is to destroy the Mega-Weapon. Using the Golden Weapons, which Jay has seemingly stolen from their past selves, the Ninja, with the help of Sensei Wu, destroy the Mega-Weapon, and everything changes back to the way it was, removing the Mega-weapon from the timeline. When everything resets, no-one but the Ninja seem to remember the Mega-Weapon existed, seemingly confirming that their quest has become far easier.
