Trivia

 * By the end of Season 5, only two of the four ninja of the original team are human, as Zane is a nindroid and Cole is a ghost
 * Technically, all of the Ninja have the title "Master," as they are all Masters of an element.
 * This was shown in "The Corridor of Elders," when Arcturus identified Lloyd as "Master Lloyd."
 * At some point, all members of the team (and some allies) have turned against their allies at some point:
 * Garmadon was turned evil in his childhood by the Great Devourer and was the main antagonist of the Pilot Episodes and half of the second season.
 * Lloyd was a minor antagonist in Season 1 and was possessed by Morro in Season 5.
 * Cole was hypnotized by Skales.
 * Nya, Cole, Jay, and Zane were corrupted by Dark Matter (although the last three were only briefly corrupted before Lloyd undid the effects).
 * P.I.X.A.L., Cyrus Borg, and Sensei Wu were controlled by the Overlord.
 * The Elemental Masters were competing in Master Chen's Tournament of Elements.
 * Skylor was working for Chen.
 * Kai was corrupted by the Staff of Elements.
 * Ronin was the main antagonist in "Shadow of Ronin," and betrayed the Ninja in "The Crooked Path."
 * Misako was controlled by Ronin in "Shadow of Ronin ", and by Bansha in "Grave Danger."
