# List of Ninjago characters

The following is a list of fictional characters from the Danish-Canadian animated television series Ninjago and its sequel, which were produced by The Lego Group. The series features a large ensemble cast of recurring characters. The list includes the main protagonists, major and minor villains and other supporting characters that have appeared within the Ninjago universe. The list is mainly organised into groups of fictional beings based on the chronological order of season release.
Ninjago focuses on a group of six teenage ninja, named Lloyd Garmadon, Kai, Cole, Jay, Zane and Nya, and their wise sensei, Master Wu. The ninja team's purpose is to battle against the forces of evil, including Wu's brother, Lord Garmadon. The series is mainly set on Ninjago Island, centred around the large metropolis of Ninjago City, which is inhabited by a large cast of supporting characters and villains, such as Nindroid armies and ghosts. The series was created to coincide with the Lego Ninjago line of construction toys, which is based on the characters and events of the series. It was created by Michael Hegner and Tommy Andreasen, two Danish film producers.

## Main
### Lloyd Garmadon

Lloyd Montgomery Garmadon (voiced by Jillian Michaels in Seasons 1–7 and Sam Vincent from Season 8 onward) is the Green Ninja and Elemental Master of Life, which grants him the ability to manipulate energy. He is the current leader of the ninja, son of Garmadon and Misako, nephew of Master Wu and the grandson of the First Spinjitzu Master. He frequently wields either a katana or dual katanas. Lloyd makes his debut in the first season as a mischievous child wanting to be an evil warlord like his father, which results in childish schemes that are foiled by the original four ninja. Lloyd is reformed by the ninja and Master Wu, before discovering his destiny as the prophesied Green Ninja. While initially mischievous and naive, Lloyd is tempered by experience over the course of the series to become a mature, wise and skilled ninja. Although he is depicted as the youngest member of the team, Lloyd's character has been developed to be its natural leader.

### Kai

Kai (voiced by Vincent Tong) is the red ninja and Elemental Master of Fire. Like Lloyd, he frequently wields either a katana or dual katanas. His elemental power grants him limited pyrokinesis and heat resistance. Kai is fiercely loyal to his friends and family, often willing to do anything to ensure their safety. He often acts on emotion instead of reason, causing him to be hotheaded, cocky, and rash. He also has a strong sense of responsibility towards his friends. Kai is the older brother of Nya and son of Ray and Maya. His love interest is Skylor Chen.

### Jay Walker

Jay Walker (born Jay Gordon) (voiced by Michael Adamthwaite) is the blue ninja and Elemental Master of Lightning. He frequently wields nunchucks and more recently, a kusarigama. His elemental power grants him limited electricity manipulation. He is also a skilled mechanic and is technologically savvy. Jay is inventive and quick-witted, often using comedy to alleviate stressful situations. He is easily excitable and prone to freaking out when in crises but like the other ninja is intensely loyal to his friends, especially his Yang/girlfriend Nya. He is the son of Cliff Gordon and the previous Elemental Master of Lightning, but was adopted and raised by Ed and Edna Walker. After the Merge, Jay found himself in the Administration, where he became the manager of realm reassignment. The Merge also caused him to lose his memories of who he was and his travels with the other ninja. A year after Imperium was liberated, Jay left the Administration and was recruited by Ras, only to be cast away following his loss to Nya in the Tournament of Sources.

### Zane

Zane (voiced by Brent Miller) is the white/titanium ninja and Elemental Master of Ice. He frequently wields three-pointed shurikens and, for the eight, ninth and tenth season, a bow and arrow. His elemental power of Ice grants him limited cryokinesis. Zane is intelligent and calculating, often providing intel to the ninja when required. Initially, he lacks normal social skills, such as a sense of humor, but it is later revealed that Zane is secretly an android (or "Nindroid"), a fact unknown to both the ninja and Zane himself. Though he is still logical and matter-of-fact by nature, his brotherhood with the other ninja has enabled him to develop more human characteristics. He is the son/creation of Dr. Julien. His love interest is P.I.X.A.L.

### Cole

Cole (voiced by Kirby Morrow from Pilots–Seabound, Andrew Francis from Crystalized onward) is the grounded and solid black ninja and Elemental Master of Earth. He frequently wields a scythe and, in recent seasons, a war hammer. His elemental power grants him limited earth manipulation and super strength. The original leader of the ninja, he is loyal to his friends and family and has a special love for food, especially cake. He is the son of Lou, a member of a barbershop quartet, and Lilly, the previous Elemental Master of Earth, who died due to an illness when Cole was still a child.

### Nya

Nya (voiced by Kelly Metzger) is the light blue ninja, Elemental Master of Water and the original Samurai X. She frequently wields a spear. In early seasons she wears red as Samurai X. Since the release of The Lego Ninjago Movie, she has primarily been depicted in gunmetal grey. Her elemental power grants her limited hydrokinesis. Although she is not an original member of the ninja team, Nya joins when her skills as the Elemental Master of Water are needed to defeat the ghosts and the Preeminent in Season 5. Tough and determined, she refuses to let anyone tell her what to do. Though she can sometimes be stubborn, Nya cares about her friends and family, often making the mature decisions in the group and serving as emotional support. As a skilled mechanic, she often constructs vehicles for the other ninja. Nya is Kai's younger sister and the daughter of Ray and Maya.

### Arin

Arin (voiced by Deven Mack) is a ninja and one of Lloyd's protégés. As a kid, he idolized the Ninja with desire to become one. He lost his parents after The Merge and somehow managed to teach himself Spinjitzu, an ability thought impossible, which eventually became a technique inadvertently invented called Object Spinjitzu when he discovered he can transfer Spinjitzu to inanimate objects. During the Tournament of the Sources, he began to fall out with the Ninja, eventually leaving them and joining Lord Ras to find his parents.

Sensei/Master Wu (voiced by Paul Dobson, Caleb Skeris as a baby, Madyx Whiteway as a child) is the wise, ancient master of the ninja who frequently wields his father's staff. He is Lloyd's uncle, younger son of the First Spinjitzu Master and brother to Garmadon. Because of his Oni heritage, Wu has lived for thousands of years.
