This is a list of characters from the Lego Ninjago: Masters of Spinjitzu animated series and related media.
Main Characters
Kai (voiced by Vincent Tong) – Originally the impatient newbie of the Ninja team, Kai eventually comes to accept his place in the team. In Season 6, Kai becomes focused on being a celebrity, more so than doing his job. He is sometimes the Ninja's field leader, in Lloyd's absence. As of episode 32, Kai can shoot fireballs out of his hands. Kai is Nya's brother, and is in love with Skylor (although his relationship with Skylor is not mentioned after Season 4). (Main, 1-)
Jay Walker/Gordon (voiced by Michael Adamthwaite) – A quick-witted Ninja, who has developed a romantic relationship with Nya. As of episode 32, he can shoot lightning out of his hands, either to attack enemies or to propel himself through the air.
Zane (voiced by Brent Miller) – Zane is usually calm, level-headed and emotionless, though he temporarily becomes more emotional in Seasons 3 and 4. Zane is a robot (as discovered in episode 7), giving him special abilities, including being able to flip gadgets out of his arms, and see out of the eyes of the Falcon. These are enhanced after P.I.X.A.L.’s AI is placed inside of him. As of episode 32, Zane can shoot ice out of his hands, though this is rarely used. Zane was created by Dr. Julien, and develops romantic feelings for P.I.X.A.L. in Season 3.
Cole (voiced by Kirby Morrow) – While originally introduced as the Ninja's goal-oriented and "fearless" field leader in the pilot episodes, Cole becomes much more laid-back and flippant by Season 1, ceasing to lead the team and leaving the Ninja without a formal field leader (until Season 3). Cole possesses super strength and, as of episode 32, he can create rocks and cause earthquakes. In addition, Cole became a ghost in episode 48, giving him the power to become intangible at will and possess objects, but also decreasing his morale. Cole became human again in Day of the Departed. (Main, 1-)
Master Wu (voiced by Paul Dobson) – The calm, patient mentor of the Ninja. He is the First Spinjitzu Master's son, Garmadon's brother, and Lloyd's uncle. (Main, 1-)
Nya (voiced by Kelly Metzger) – A capable mechanic and fighter who usually helps the Ninja, but is often underestimated by them. Although shown to be independent and fearless in the pilot episodes, as the story progress Nya becomes less confident, and by Season 6 professes to feel much angst about being female. Nya also has an alter ego as Samurai X, a samurai with a giant mech and high-tech gadgets. In Season 5, Nya becomes a Ninja, allowing her to shoot streams of water out of her hands. Nya is Kai's sister and Jay's girlfriend. (Main, 1-)
Lloyd Garmadon (voiced by Jillian Michaels) – First introduced as a wannabe super villain, Lloyd eventually joined the Ninja, even becoming their leader. Lloyd was initially a child, but was brought to the age of the other Ninja by magical tea (in episode 18). Lloyd is a team player and a valued leader. He can shoot golden spheres of energy out of his hands (as of episode 15). Lloyd is Garmadon and Misako's son. (Main, 2-; Recurring, 1)
Lord/Master Garmadon (voiced by Mark Oliver) — Garmadon has served as an antagonist to the Ninja through Season 2 (as Lord Garmadon) and as a protagonist starting in Season 3 (as Sensei Garmadon). As Lord Garmadon, his personality changes significantly throughout the series, but his two consistent character traits are his thirst for power and his love for Lloyd. As Master Garmadon, he is the co-leader of the ninja, with Wu. He is the First Spinjitzu Master's son, Wu's brother, Lloyd's father, and Misako's husband. (Main, 3-4; Recurring, 1-2; Guest, 5)
Misako (voiced by Kathleen Barr) – A former librarian and archeologist, who has a store of knowledge concerning Ninjago mythology. Misako is Garmadon's wife and Lloyd's mother. (Main, 6; Recurring, 2-5)
"Grand Sensei" Dareth (voiced by Alan Marriott) – A dramatic and self-centered man, who claims to be a master ninja, despite his complete lack of any ninja skills. Dareth often falls in with the Ninja by mistake, frequently impairing the Ninja more than he helps them. He prefers to be addressed by the moniker "the Brown Ninja", and takes on the role of the Ninja's promoter in Season 6.
P.I.X.A.L. (voiced by Jennifer Hayward) – Cyrus Borg's robotic assistant who develops a crush on Zane, and assists the Ninja throughout Season 3. P.I.X.A.L.'s AI ultimately winds up inside Zane, where she endows Zane with even more special abilities than he would have otherwise, e.g. detecting incoming threats while Zane is distracted.
Dr. Cyrus Borg (voiced by Lee Tockar) – A genius inventor who reconstructs Ninjago City after it is largely destroyed in the Season 2 finale, transforming it into the futuristic New Ninjago City where everything is controlled by technology. Borg ultimately regrets this decision when the Overlord hacks into the system, compelling Borg to help the Ninja combat his own inventions.
Ronin (voiced by Brian Dobson) - A mercenary and pawnshop owner, whose main goal is to pay off a debt to Soul Archer. He is greedy and mostly conscienceless, although he eventually helps the Ninja after Morro and Morro's ghosts betray him (purportedly for failing to pay Soul Archer on time). Ronin mainly serves as an antihero in the series, although he appears as an antagonist to the Ninja in Lego Ninjago: Shadow of Ronin.
Falcon - A seemingly ordinary falcon who protects and helps the Ninja, particularly Zane. It is discovered to be a robot in episode 7 (shortly before Zane discovers that he himself is a robot). Subsequently, it makes use of this fact, most notably allowing Zane to see out of its eyes. It was created by Dr. Julien.
Echo Zane (voiced by Brent Miller) - A robot who looks like Zane. He helps the Ninja using his martial arts skills and ability to run on any surface, defying gravity. However, he is prone to falling apart at inopportune moments.

Skylor (voiced by Heather Doerksen) – Charismatic, careless and somewhat deceptive, Skylor's role shifts throughout Season 4. Initially appearing to help the Ninja, she is a double agent for most of Season 4, also helping her father Chen. She eventually stops helping Chen and becomes an ally of the ninja in all further appearances. Skylor can access the Elemental powers of anyone she has touched. Skylor has a romantic relationship with Kai, although this is not mentioned after Season 4.
Karlof (voiced by Scott McNeil) – A physically powerful man whose role shifts throughout Season 4. Initially Kai's nemesis, he becomes protective of Cole, and then allies with the Ninja. Karlof can turn his skin and armor into solid metal.

Neuro (voiced by Paul Dobson) – A mysterious man who sometimes helps the Ninja. He has the powers of telepathy and mind control.

Nadakhan often remarks "Your wish is yours to keep…" just before granting a wish.
