The Ninja (also known as the Masters of Spinjitzu) are a group of young warriors formed by Master Wu to protect the land of Ninjago from evil. They are the main protagonists of LEGO Ninjago: Masters of Spinjitzu. Since their formation, they have fought a large amount of foes, such as Lord Garmadon and his Skeleton Army, the Serpentine and the Great Devourer, the Overlord and his Stone Army, the Nindroids built by Cyrus Borg and P.I.X.A.L. (controlled by the Overlord), Master Chen and his Anacondrai Cultists, the Preeminent, Morro the and Ghost Warriors who escaped the Cursed Realm, Nadakhan and his Sky Pirate Crew, Clouse and his Shadow Army, Yang and his Students, Acronix, Krux, and the Vermillion Warriors. They will eventually encounter the Sons of Garmadon in Season 8, and the Oni in Season 9.

- 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 as a result of the Hands of Time meddling with the past.
- 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, as of 2017, with Nya following behind him.
- Excluding their 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.
- Kai, Jay, and Cole are the only three Ninja to have every different suit shown in the show. This is due to Lloyd and Nya joining the team later on, and Zane lacking a tournament robe, as he did not compete in the Tournament of Elements.
- Technically, all of the Ninja have the title "Master," as they are all Masters of an element.
- At some point, all members of the team (and some allies) have turned against their team and later revert back:
- Garmadon was turned evil in his childhood by the Great Devourer and was the main antagonist of the Pilot Episodes and the Mega Weapon arc of the second season.
- Lloyd was a minor antagonist in Season 1 and he 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 and nearly attacked Lloyd and Skylor.
- Morro was the main antagonist of Season 5.
- 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."
- Nya was possessed by Dilara.
- Ray and Maya were forced to work for The Hands of Time during their enslavement.
- P.I.X.A.L. as Samurai X was controlled by the Quiet One during Season 8.
- 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 now can alternate between white and silver.
- Nya was red, then azure, then maroon, and is now azure and silver.
- All six of the Ninja have seasons or TV Special that focus on them.
- Kai was the focus of the Pilot Episodes, 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."
- Lloyd was the focus of Season 2 and Season 8: Sons of Garmadon.
- Nya was the focus of Season 5 and Season 7.
- All the Ninja but Lloyd have traveled to the past. Kai is the only one who traveled to the past thrice.
- Lloyd is the only Ninja who went to the Cursed Realm and returned physical. He is also the only Ninja who has visited most of the realms due to his fight with Morro.
- Nya and Jay are the only Ninja to remember what happened in Season 6, although Lloyd showed signs of experiencing déjà vu while the rest may have gained some recollection.

- Jay's signature color is blue.
- Zane's signature color is white.
- Cole's signature color is black.
- Nya's signature color is azure.
- Lloyd's signature color is green.
- Each of the six Ninja have individual animal symbols that correspond to their characteristics (as of Season 6, depicted on their suits with matching colors and elemental resemblance).
- Kai's is shown as an orange (with red outline) Lion—resembling his aggression.
- Jay's is shown as a dark blue (with purple outline) Octopus—resembling his active nature.
- Zane's is shown as a blue (with white outline) Tiger—resembling his intelligence.
- Cole's is shown as a yellow (with orange outline) Gorilla—resembling his strength.
- Nya's is shown as a white (with light blue outline) Phoenix—resembling her determination.
- Lloyd's is shown as a yellow/gold (with green outline) Dragon—resembling his power.
- Each of the six Ninja have their own signature weapon that they are most known for and later changed their signature weapons to match their movie counterparts (except for Jay).

- Zane is the oldest Ninja of the team, although in Season 6, when Lloyd aged into a old man, he was temporarily the oldest Ninja of the team before reverting back to a teen.
- All of the Ninja have had a love interest which was a another focus in a season.
- Jay and Nya had an attraction to each other in the first two seasons and following a break-up in Season 3, they got back together and remain a couple.
- Kai had a interest in Skylor, the daughter of Chen, in Season 4: The Tournament of Elements. Their relationship is said to be explored in Season 8: Sons of Garmadon.
- Zane had an interest in P.I.X.A.L. in season 3 and they have remained together.
- Cole had an interest in Nya during Season 3 which caused a rivalry between him and Jay until she chose Jay. Cole also had an interest in Seliel but this was considered non-canon as its unknown if she actually exists in the series.
- Lloyd has an interest in Harumi in Season 8.
- As of Season 8, the Ninja now have their names and signature colors on their weapons.
