The Attack is the seventieth episode of Ninjago: Masters of Spinjitzu and the sixth episode of season seven.
Having recovered the Slow-Mo Time Blade, the Ninja are divided in their reactions, with Lloyd fearing reprisal, Kai and Nya being preoccupied with their own issues, and the others fooling around with the powerful weapon. At the Vermillion camp, Commander Blunck and Commander Raggmunk receive a dressing down from Acronix and Krux, while General Machia prepares their forces for a mission to retake the Time Blade. Wu rises from his bed and agrees with Lloyd's concerns, and is then stunned to recognize the symbol Kai had previously noted on the Vermiillion helmets; before he can explain, however, the Temple of Airjitzu comes under attack from the Vermillion. The Ninja quickly respond to the invaders while the still ailing Wu observes, and Lloyd uses his Elemental Dragon to go on the offensive after the Destiny's Bounty 2.0 is shot down.
When flying Vermillion scare him and cause the dragon to dissipate, he is unexpectedly saved by the Samurai Mech, revealing that the Vermillion were not responsible for its theft; the mech is later shot down as well, though Nya-obsessed with identifying the thief-isn't convinced that the new Samurai X has perished. The Time Twins then arrive to claim the blade, only to lose the one they already possess to the Ninja. However, Machia then swoops down and seizes both blades, and after slowing down the ninja kidnaps Wu, who has been unable to explain the meaning of the marking to Kai. As the Ninja contemplate their defeat, Kai realizes where he's seen the mark before: in his family blacksmith shop.
