Trivia

 * All of the Ninja have changed their physical appearances in the show.
 * Jay, Kai, Zane, and Cole turned into kids in "Child's Play," but turned back to teenagers.
 * Lloyd was a child until he was hit by Tomorrow's Tea in "Child's Play" and aged into an old man in "Wishmasters." He reverted back to a teen due to Jay's last wish.
 * Zane was originally a Nindroid in human form until "The Titanium Ninja" and debuted in his titanium form in "The Invitation."
 * Cole was a human being until "The Temple on Haunted Hill," where he was turned into a ghost by Yang but turned human again in "Day of the Departed." He now has a scar from the transformation.
 * Nya's lips are no longer red following Season 6 onward.
 * In Season 8, all Ninja will have different appearances similar to their movie counterparts.
 * Zane and Nya are the only Ninja to have died in the series but were both resurrected.
 * Jay is the only Ninja to appear in every Ninjago episode with Nya following behind him.
 * Excluding allies, Nya is the only female on the team.
 * After Cole's physical reformation in "Day of the Departed," Zane becomes the only non-human on the team.
 * 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 team:
 * Garmadon was turned evil in his childhood by the Great Devourer and was the main antagonist of the Pilot Episodes and both the first and 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 Master 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 briefly corrupted by the Staff of Elements.
 * Ronin was forced by Morro to betray the Ninja in "The Crooked Path" and hired by the police to capture the Ninja "Public Enemy Number One."
 * Misako was controlled by Bansha in "Grave Danger."
 * Ray and Maya were forced to work for The Hands of Time during their enslavement.
 * Although Lloyd is the leader of the team, every Ninja has taken on the role of the leader.
 * The Ninja (except Nya) can only harness their elemental powers by being dependent on their leader Lloyd. This may due because Lloyd shares his Golden Power with them.
 * Excluding Nya, the Ninja are the only Elemental Masters that have the main elements in Ninjago (Water is a secondary element).
 * Three of the Ninja have had their main color changed.
 * Lloyd was green, then gold, but is now green again.
 * Zane was white, then silver, but is now white again.
 * Nya was red, then azure, then maroon, and is azure again.
 * All six of the Ninja have seasons or TV Special that focus on them.
 * Kai was the focus of Season 1, Season 4, and Season 7.
 * Jay was the focus of Season 1 and Season 6.
 * Zane was the focus of Season 1 and Season 3.
 * Cole was the focus of Season 1 and Day of the Departed. He may play a role in Season 8.
