Ninjago: Masters of Spinjitzu


 * Lloyd Montgomery Garmadon (voiced by Jillian Michaels in Seasons 1–7 and Sam Vincent in Seasons 8-present) is the Green Ninja and Elemental Master of 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.[3] Lloyd's powers are vaguely defined, a fact admitted by his friends, but he possesses the ability to manipulate energy (ergokinesis). Lloyd made his debut in Season 1 as a mischievous child wanting to be an evil warlord just like his father. This resulted in childish schemes that were often foiled by the original four Ninja. Lloyd was eventually captured and reformed by the Ninja and Master Wu, Lloyd's paternal uncle, and eventually discovered his destiny as the Green Ninja. While initially mischievous and naive, Lloyd has been tempered by experience and time into a mature and capable ninja. Though still the youngest, he has emerged as the natural leader of the Ninja, displaying wisdom beyond his years. Lloyd greatly appreciates his friends, saying that it was them who taught him the "importance of being brave, of being strong, and most importantly, being good". He believes the team's strength comes from "no one being more important than the other". Lloyd can still be rash in matters of family (especially regarding his father).
 * 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, feeling enormous guilt in situations where his friends suffer, such as when Zane sacrificed himself in Season 3 and when Lloyd was possessed in Season 5. Kai is the elder brother of Nya and son of Ray and Maya.
 * 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 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.
 * Zane (voiced by Brent Miller) is the White/Titanium Ninja and Elemental Master of Ice. He frequently wields three-pointed shuriken and, more recently, a bow and arrows. His elemental power grants him limited cryokinesis. Zane is intelligent and calculating, often providing intel to the other ninja as it applies to their situation. Initially, he lacks normal social skills, such as a sense of humour, but he also has the ability of sixth sense. 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.
 * Cole (voiced by Kirby Morrow) 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 very 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.
 * Nya (voiced by Kelly Metzger) is the Silver/Maroon Ninja, Elemental Master of Water and the original Samurai X. She frequently wields a sword and, more recently, a spear. Her elemental power grants her limited hydrokinesis. Originally not a part 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 truly does care about her friends and family, often making the most mature decisions of the group and serving as emotional support. A skilled mechanic, she often constructs vehicles for the other Ninja. Nya is Kai's younger sister and the daughter of Ray and Maya.
 * P.I.X.A.L. (Primary Interactive X-ternal Assistant Life-form) (voiced by Jennifer Hayward) is a female nindroid who was originally an assistant to her creator/father Cyrus Borg. She joins the Ninja team after being influenced by her fellow nindroid Zane. She is disassembled in Season 4, but is then uploaded into Zane's system as an artificial intelligence. In Season 7, she secretly rebuilds herself and becomes the new Samurai X. She often provides technical support to the Ninja while serving as Zane's love interest.
 * 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 over a thousand years.
 * Lord/Sensei/Emperor Garmadon (voiced by Mark Oliver, Kai Emmett as a child) is Lloyd's father, Wu's older brother, Misako's estranged husband, and older son of the First Spinjitzu Master. Garmadon is the main antagonist for the first two seasons but is later cleansed of evil and becomes a sensei to the Ninja. In Season 4 he is sacrificed to the Cursed Realm to stop Master Chen's Anacondrai army. Garmadon is later resurrected in Season 8 by the Sons of Garmadon as a being of pure evil and proceeds to conquer Ninjago, proclaiming himself as the realm's new emperor. However at the end of Season 9, Garmadon's reign of terror is finally brought to an end and he is imprisoned in Kryptarium Prison. In Season 10, he is released to help the Ninja defeat the Oni, after which he walks free. His whereabouts are currently unknown. Because of his Oni heritage, Garmadon has lived for over a thousand years.

They consist of five tribes, the Anacondrai, Hypnobrai, Fangpyre, Constrictai and Venomari. The Serpentine held a prophecy that foretold the coming of the evil Golden Master, but their attempts to warn the humans resulted in them being entombed underground.

He swallows a shrinking pill that was meant for the Overlord, which shrinks his size. In Season 4, he is captured by Master Chen and his sweat is used to permanently transform Chen’s Fake Anacondrai Army, but he finds a way to defeat them by releasing the spirits of the Anacondrai generals.
