Cole

Ninja are warriors trained in the ancient martial art of Spinjitzu. Originally, Master Wu gathered four young people—Kai, Cole, Jay, and Zane—to find the Golden Weapons and protect Ninjago from Lord Garmadon. They were later joined by Lloyd and Nya. Each ninja masters a different element: Kai masters Fire, Cole masters Earth, Jay masters Lightning, Zane masters Ice, Nya masters Water, and Lloyd masters Energy. The ninja aren't just masters of power; they've been trained by Master Wu and sworn to protect the innocent. Their headquarters is the Monastery of Spinjitzu, and their home is the flying ship Destiny's Bounty.

Spinjitzu is a martial art practiced by ninja. It involves the warrior spinning at incredible speed, creating a tornado of their element. To master Spinjitzu, one must unlock one's True Potential—overcoming the emotional barriers that hold back their power. Master Wu teaches this art, and it is Spinjitzu that distinguishes ninja from ordinary people. There is also the Tornado of Creation—a collaborative technique where four ninja combine their powers to create a powerful attack capable of destroying an entire army. Forbidden Spinjitzu is a technique created by the First Spinjitzu Master that amplifies power to the extreme, but also corrupts the user.
The Four Golden Weapons are artifacts forged by the First Spinjitzu Master from the gold of the Golden Peaks: the Scythe of Quakes (Earth), the Sword of Fire (Fire), the Nunchaku of Lightning (Lightning), and the Shurikens of Ice (Ice). No one can use the full power of the four weapons simultaneously—doing so would destroy the user. Lloyd later gained the Golden Power, becoming the Golden Ninja, but gave it up to share it with the other ninja.

The First Spinjitzu Master was the creator of Ninjago. He was half Oni, half Dragon, and wielded the powers of Creation and Destruction. He forged the Golden Weapons and created the world. His sons were Wu and Garmadon. He lived for thousands of years and died, leaving behind a map to the Golden Weapons.

Cole is the Earth Ninja, the Black Ninja, and the Elemental Master of Earth. He has a muscular, powerful build—he's the strongest on the team even without using his elemental powers. He has dark hair and brown eyes. He wears a black ninja suit with gold accents: gold accents on his helmet, shoulder pads, and back.

Cole was born into a family of artists: his father, Lou, was a renowned dancer and singer. As a child, his father sent Cole to performing arts school, but fame wasn't for him—Cole secretly ran away to find his own path. He loves simple things: nature, rock climbing, old technology, and, most of all, cake. Cole possesses tremendous physical strength, which has saved the team on more than one occasion. Despite his confidence, he remains very pragmatic. Cole is the team's "rock foundation": reliable, calm, yet stubborn and sometimes overconfident. His parents are Lou and Lily. Lily is deceased.

Kai is the Fire Ninja, the Red Ninja, and a master of the Fire Element. He has thick, tall, spiky brown hair shaped like flames. He has a muscular, toned build and stands approximately 178 cm tall. He has sharp features and amber eyes. He wears a red ninja kimono with gold and orange accents. In everyday life, he is often seen wearing a white shirt and red pants with an orange blacksmith's apron. Kai was born in the village of Ignacia, the son of Ray and Maya, who owned the Four Weapons shop. He has a younger sister, Nya. When their parents disappeared, Kai took over the care of his sister and the family business, vowing to surpass his father. Kai was the fourth to join the team and the first to quickly master his element—fire. His gift was the strongest of the four, but he has trouble controlling himself: he's hot-tempered, impatient, and always rushes into battle first. Kai is Lloyd's best friend, and while he prefers to act alone, he's learned to trust a team in times of crisis. He can't swim and is afraid of water, but he once jumped in to save a drowning Lloyd.

Jay is the Lightning Ninja, the Blue Ninja, and the Elemental Master of Electricity. He has short, straight, reddish-brown hair with a shaved corner of his right eyebrow. He wears a blue kimono. In everyday life, he wears a blue jacket with a white stripe over a white T-shirt and blue pants. He has a slim build and isn't the strongest, but he's very agile. He's 18 years old. His real name is Jay Gordon, but he goes by his adoptive parents' last name, Walker. His biological father is Cliff Gordon, the actor who played Fritzdon, and his mother is the previous Elemental Master of Lightning. Jay was abandoned by a foster family, where he was raised by junkyard caretakers. He's a genius inventor who loves technology and video games, but his experiments often end in explosions. Jay is the team's jokester: when the going gets tough, he's always ready to tell a joke. He's madly in love with Nya, and when it comes to her, this talkative ninja becomes tongue-tied. Jay can generate up to 1.21 gigawatts of electricity.

Zane is the Ninja of Ice, the White Ninja, and the Elemental Master of Ice. He is a Nindroid, a robot created by Dr. Julien to protect those who cannot protect themselves. His body is silver, as is his hair. His eyes are blue dots, and his face bears robotic markings. He wears white ninja armor. In his human form, he had light brown hair and blue eyes. After transforming into a titanium body, he became more "mechanical" but retained his familiar appearance. For a long time, Zane did not know he was a robot and considered himself an orphan. He searched for an answer to the question "Who am I?" and the answer was unexpected: he is a machine. This did not change his friendship with the team, although he sometimes felt lonely. Zane is calm, pragmatic, and sometimes appears cold, but in reality, he is deeply attached to his friends.

Nya is the Ninja of Water, a Master of the Element of Water, Kai's sister, and Jay's girlfriend. She has long black hair tied in a ponytail with a ribbon, and wears bright lipstick. She has a beauty mark on her right cheek. Her ninja kimono is predominantly gray, azure, and blue. As Samurai X, she wore a large gold bracelet with a red gemstone on her left wrist. Since childhood, she wanted to be a ninja, but was rejected because of her gender, so she created the Samurai X armor and began secretly assisting the team under this guise. Nya is a brilliant inventor; she created the Samurai X suit and much more. Wu later trained her to control the element of water, and she became a full-fledged member of the team. Nya long struggled with being labeled "Kai's sister" and longed to be seen as a hero in her own right.

Lloyd Garmadon is the Green Ninja, Golden Ninja, and Elemental Master of Energy. He has blond hair, brown eyebrows, and green eyes that glow when using his powers. In Season 8, he matured, his voice deepened, and his design was updated. Previously, he had black eyes and dark eyebrows. He is the son of Lord Garmadon and Misako, nephew of Master Wu, and grandson of the First Spinjitzu Master. As a child, he was a mischievous child who wanted to follow in his father's footsteps and become a villain, but fate decreed otherwise: he became the prophesied Green Ninja, destined to save Ninjago. Lloyd is the most powerful Elemental Master because he can harness the powers of all the other ninja. He rose from a helpless child to the team's leader, surviving his father's betrayal, the loss of his powers, and numerous battles. His biggest pain is his relationship with his father: Lloyd always wanted to believe that there was good in Garmadon.

Master Wu is a wise old man, the ninja's mentor, and the Dragon Master. He is the second son of the First Spinjitzu Master, Garmadon's younger brother, and Lloyd's uncle. He has white eyebrows, a long gray beard, and wears a straw hat and a white robe. He loves tea. When using Spinjitzu, his spins turn golden. Wu inherited the Element of Creation from his father. His first student was Morro, the Master of Wind, who escaped the Cursed Realm. Wu trained Cole, Zane, Jay, Kai, and Lloyd, as well as Nya. He has endured many trials. Wu is a voice of wisdom and a mentor who, despite all his mistakes, remains the one the ninja turn to for advice.

Lord Garmadon is the eldest son of the First Spinjitzu Master, Wu's brother, and Lloyd's father. His appearance changed after being bitten by the Great Devourer: he became demonic with four arms, glowing red eyes, sharp teeth, and horns. He wears black samurai armor with a tall, horned helmet. He was once good, but was infected with evil (the Great Devourer's venom), which gave birth to evil within him. He was cast into Wu's Netherrealm but later returned. Garmadon is a complex character: he is a villain, but there's always been a sliver of good within him.

Morro is Wu's first disciple, the Master of Wind. He appears as a handsome young man with black hair, green pants, and a light green shirt with the Wind symbol. His eyes often glow green or blue. He wears black clothing with ghostly elements: chains, a veil, and torn fabric. When he possessed Lloyd's body, his appearance changed: black pants with dark green accents, a green shirt, a black mask, and shoulder pads. He was chosen by his mentor to become the Green Ninja, but the prophecy failed, breaking him. After his death, Morro became a ghost and later possessed Lloyd's body to seek revenge. He sought to free his master, the Preeminent, and curse all sixteen realms.

Misako, also known as Koko, is Lloyd's mother and Lord Garmadon's ex-wife. She has short red hair and wears brown pants. As Lady Steel Dragon, she wears black battle armor with a crown and quiver. She is intelligent, strong, and independent, always protective of her son.

Besides Ninjago, there are fifteen (according to other sources, sixteen) other parallel worlds, all of which are connected in pairs: if one world is destroyed, its "sister realm" also perishes. Ninjago and the Underworld are not sisters. Known worlds include: the Underworld (a realm of skeletons), the Cursed Realm (a prison for villains, destroyed by Nya), the Djinn Realm (Djinjago, the Cursed Realm's sister, was destroyed along with it), the Cloud Realm (a realm where destinies are written), the Realm of Oni and Dragons (a desert world where the Oni dwell), the Never-Never Realm (an icy world where Zane was exiled), the Digital World (Digiverse), the Realm of Chima, and others. Other worlds can be accessed using the Realm Crystal, Tea Leaves, Dragons, or magic.

Ninjago Island – Created by the First Spinjitzu Master using the four Golden Weapons, the world was originally called Ninjago, but was later divided into a light side (Ninjago proper) and a dark side (the Netherrealm, home to the skeletons and Garmadon). The island includes locations such as Ninjago City, Jamanakai Village, the Toxin Swamps, Mount Solitude, the Wasteland, the Frozen Lands, and many others. Ninjago City is the largest city and the center of most of the action, built in layers: the old fish market and docks at the bottom, shopping streets in the middle, and skyscrapers with high-end restaurants at the top.

The Serpentine are an ancient race of snake-like creatures that once lived underground and were sealed away.
The main tribes are Hypnobai (hypnosis), Anacondrai (invisibility), Constrictai (strength), Phantoms (poison), and Venari (speed). Their leaders are Pythor the Devourer (Anacondrai) and Scales (Hypnobai). In Season 4, "The Tournament of Elements," the Fake Anacondrai appear—people who, with the help of Master Chen's magic, took on the form of snakes in order to take over Ninjago.
