Season 1: Masters of Spinjitzu is the first season of LEGO Ninjago (Earth-87). Lord Garmadon serves as the main antagonist, leading an army of Skulkin. There is no focus ninja.
This season is based on the Pilot Episodes and Episodes 1-6 from Season 2 of the official LEGO Ninjago series, but it takes place in Earth-87, a place where the characters adopt their personalities and events play like in Earth Prime, but plot and character development occur slightly differently.
Thirty-five years after Garmadon was banished to the Underworld, Skulkin armies raid Ninjago and Sensei Wu realizes he cannot protect Ninjago alone, so he assembles a young group of four ninjas (Kai, Jay, Zane, and Cole) to fight them.
