  • the Sword of Fire
  • the Nunchucks of Lightning
  • the Scythe of Quakes (earth)
  • the Shurikens of Ice

Wu and Garmadon fought, and the older brother, Garmadon, was banished to the Underworld. Peace didn't last for long, as Garmadon had sent Skeletons from the underworld to steal the four Weapons. Sensei Wu found four teenagers to train as ninja; Kai, Jay, Cole, and Zane, one of whom, Kai, had a sister, Nya, who had been captured by the Skeletons.
