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. Since the team's formation, they have fought many enemies. After Cole, Kai, Jay, and Zane united, they fought Lord Garmadon and the Skulkin, and later, Pythor and the Serpentine, which were freed by Lloyd Garmadon, who would later be revealed to be the legendary Green Ninja. Lord Garmadon defeated the Great Devourer, he escaped with the Golden Weapons and led the Serpentine.

After the ninja destroyed his Mega Weapon, Garmadon came in league with The Overlord and the Stone Army. The Overlord possessed Garmadon to regain his true form, and Lloyd fulfilled his destiny by becoming the Ultimate Spinjitzu Master and vanquishing the Dark Lord, purifying the world and his father.

As the years went on, the ninja faced further obstacles and adversaries and even gained a new recruit, Nya, who joined the team as the Water Ninja. They battled the Golden Master and the Nindroid Army, Master Chen and the Anacondrai Cultists, the Preeminent and the Ghost Warriors (including Morro), Nadakhan and the Sky Pirates in an erased timeline, Clouse and the Shadow Army, and the Time Twins and the Vermillion.

After Wu's disappearance, Lloyd achieved the rank of Master, and since Wu's return a year later, they have fought Harumi and the Sons of Garmadon (in addition to the resurrected Lord Garmadon himself), Iron Baron and the Dragon Hunters, and the Omega and the Oni.

After a six-month-long period of peace, they battled Aspheera and the Pyro Vipers, the Ice Emperor (discovered to be an amnesiac Zane manipulated by General Vex) and the Blizzard Samurai. After returning to Ninjago, the Mechanic helped Unagami and his army escape from the video game known as Prime Empire into the real world by trapping players in the game and using them as a power source to create a Manifestation Gate. Jay and Zane found the game's creator Milton Dyer who convinced Unagami to free the Gamers trapped inside the game.

Sometime after freeing the trapped gamers, the ninja wound up in the Dungeons of Shintaro, where they faced off against the Skull Sorcerer and his army of Re-Awakened while ending a war between the Munce and the Geckles. With the power of the Spinjitzu Burst, Cole defeated the masked villain, freeing the two tribes from his tyranny, and the ninja and their master went off in search of another adventure.

Upon hearing no word from Wu and Misako, the ninja head for the Island of the Keepers where they come across the Keepers of the Storm Amulet, who trade Jay to Wojira, only to learn that it was Ronin, who had been deceiving them for their treasures. With help from the survivor, they were able to defeat Ronin. Eventually, energy pulses would begin to make Nya's powers stir out of control, and they would find that it was coming from the Tartarus Trench. The villain, Kalmaar, requires the Storm Amulet, and he is able to gain it, awakening Wojira. As a last resort move, Nya becomes one with the Endless Sea, defeating Wojira and leaving the team.

One year following the incident with Wojira, the remaining five ninja decided to band together to uncover the Vengestone smuggling scheme. During their disbandment, a new group enters the scene, somewhat replacing them in society. When Nya returns, she requested for her elemental powers to be removed. With little options, the boys decide to release Wu's old foe to bring their ally back but at the cost of becoming criminals. More bad news arrives when the Overlord, now under the name Crystal King, was recruiting the Ninja's enemies with help from his servant: Harumi. With help from Garmadon, the paperboys, some escaped criminals, and Harumi, whom learnt of how the Overlord was responsible for the Great Devourer, the Ninja once again defeat the Overlord, at the cost of the Golden Weapons and the four original Ninja's powers.

During the Merge, the ninja went missing and were scattered across Ninjago's new landscape. Years later, Lloyd took to training two new ninja, Arin and Sora in their absence to combat the forces of Imperium. Soon after, Kai, Nya, and Zane rejoined the group, but Jay remained with the Administration Agents (unbeknownst to the other ninja) and Cole chose to search for Master Wu.

## History

### Pilot episodes

Dreading the return of his evil brother, Lord Garmadon, who is desperate to claim the Golden Weapons of Spinjitzu, Master Wu, the younger son of the First Spinjitzu Master who created Ninjago with the weapons, searched the land for four teenagers to find the weapons first. He came across the current Elemental Masters of the Elements of Creation: Cole—the Master of Earth, Zane—the Master of Ice, Jay—the Master of Lightning, and Kai—the Master of Fire, whose sister Nya had been kidnapped by Garmadon's army of Skulkin, though none of the four had unlocked their respective Elemental Powers yet. With Wu's teaching, the four became ninja, learned the art of Spinjitzu, and retrieved all but the last weapon, the Sword of Fire. Unfortunately, Garmadon used Nya to lure Kai to the Fire Temple and stole the sword while the Skeleton Army snuck up on the sleeping ninja and stole the other three weapons.

Wu followed the Skulkin general Samukai to the Underworld while the ninja followed him by taming the four dragons who guarded the Golden Weapons.

The four watched as Wu and Samukai fought, the former only possessing the Sword of Fire against Samukai with the other three weapons, giving him the advantage. Samukai eventually gained a hold of all four and intended to use them against Garmadon, however, their immense power overwhelmed him leading to his death, the ensuing tear through space and time allowing Garmadon to escape to the Realm of Madness, which would enable him to wield all four weapons without death. Once the ninja, along with Nya, had moved to Wu's Monastery, they continuing their training for Garmadon's return.

### Rise of the Snakes

Unfortunately, lack of action led them to laziness, preferring to play video games instead of staying fit and powerful. Unbeknownst to them, a new threat was brewing. Wishing to live up to his father's feared name, while harboring feelings of sadness for his dad's departure, Garmadon's son Lloyd sought to cause chaos in Ninjago, and achieve his selfish desires in the process. After the ninja made a fool of him, he inadvertently led to the successful release of all five tribes of the mythical Serpentine (one tribe, the Hypnobrai, burning down Wu's Monastery, forcing the team to relocate to the *Destiny's Bounty*, a damaged pirate ship Zane found by following a mysterious Falcon), now led by the last of the Anacondrai, Pythor P. Chumsworth, who seeks the Fangblades to awaken the Great Devourer, the monster responsible for turning Garmadon's heart evil.

The ninja battle the united Serpentine, while a mysterious samurai continuously steals their thunder. Eventually, Lloyd, who was taken in by the ninja after being betrayed by the snakes, is captured and Wu leaves to find someone who can help free him. On their own, the ninja engage in battle with the Serpentine to stop the awakening of the Devourer, each one unlocking their true potential in the process (with the team learning Zane is a Nindroid). They also learn Nya is the Samurai due to being left out.

Wu returns with Garmadon to help save Lloyd, who to everyone's surprise (and Garmadon's dismay) is the Green Ninja, the warrior prophesied to defeat the "dark lord." Though the ninja, with Garmadon's help, recover all four Fang Blades, Pythor steals them and manages to awaken the Great Devourer, though it devours him and Wu. The Devourer was only able to be defeated by Garmadon with the help of the ninja, wielding all four Golden Weapons, the "dark lord" escaping afterward.

Finding Wu in a puddle of the Devourer's venom, the ninja promise to train Lloyd so he'll be ready for the decisive battle against his father.

### Legacy of the Green Ninja

After the defeat of the Great Devourer, the ninja, along with the Green Ninja, fought against Garmadon and the remaining Serpentine army. Garmadon tries to get rid of the ninja using his newly made Mega Weapon many times in order for Lloyd to not become the Green Ninja but they eventually destroyed it with help from the past versions of the Golden Weapons. Lloyd also used Tomorrow's Tea to age up in the process.

After Garmadon was betrayed by the Serpentine, he came across an evil spirit called the Overlord and formed an alliance with him to take over Ninjago. But the Overlord ended up possessing him and turn him into his true Dragon form to purge Ninjago into pure Darkness. Luckily Lloyd, having become the Golden Ninja thanks to the other ninja, was finally able to defeat him and Garmadon returns to normal along with anyone else being corrupted by the Dark Matter.

### Rebooted

Ninjago was at peace, thanks to Lloyd, who defeated the Overlord, but he returns, having integrated himself into the Borg Industries' computer systems. The ninja had to fight again with the Overlord, only now with an old enemy, Pythor, and an army of Nindroids created based on Zane's blueprints to serve the Overlord.

However, the ninja emerged victoriously, but at the cost of Zane, who sacrificed himself. Unbeknownst to the others, however, Zane's mind and spirit had transferred into the Digiverse and managed to rebuild himself.

Soon after, however, he was captured by a thief named Ronin along with his fellow Nindroid/girlfriend, P.I.X.A.L.. Zane was taken to Garmadon's old mentor, Chen, where he was stripped of his power and held hostage.

### Tournament of Elements

After the apparent sacrifice of Zane, the ninja are divided, where they part ways. However, everything changed when Lloyd attempts to bring them back together and they discovered that Zane was still alive. To rescue him they had to go to Chen's Island and take part in the Tournament of Elements.

During this time, they discovered the truth of their powers after they met and befriended the Elemental Masters. The ninja was also able to unlock the ability to use Elemental Dragons.

The ninja allied with their new friends and old ones to make one final effort at the Corridor of Elders in order to defend their home against Chen and his cult of Anacondrai worshippers.

With the sacrifice of Garmadon, Chen and his army were banished to the Cursed Realm, officially bringing peace between the Serpentine and the humans.

### *Shadow of Ronin* (non-canon)

*Main article: History of the ninja (Shadow of Ronin)*
### Before Possession

At some point in time, the ninja had another encounter with Ronin, who ultimately abandoned them in a precarious situation.

### Possession

When opening the portal to the Cursed Realm, a ghost named Morro, who was the first student of Master Wu, came out and possessed Lloyd and shortly after takes the Realm Crystal and liberates the Preeminent, the physical embodiment of the Cursed Realm. The ninja was faced with problems, as their power depended on Lloyd, which left them powerless, and Cole was turned into a ghost, and Ronin betrayed them to the Ghost Warriors. However, things shifted for the better as they learned a new technique Airjitzu and Cole learned how to accept his form and learned some new ghost moves. Nya also learned she was the master of Water and trained to use her powers.

Eventually, Lloyd was freed of his possession in exchange for the Realm Crystal and the ninja regain their powers and put up a better fight with the ghosts.

In the end, thanks to Nya, who unlocked her True Potential, they defeated the Preeminent and Morro, thus sending them to the Departed Realm along with the rest of the Ghost Warriors as well as the people who were still trapped in the Cursed Realm, including Chen and Garmadon. With this, the ninja achieved victory and gained a new member for their team.

***The following events were undone due to Jay's final wish, and thus, did not happen in the current timeline.***

### Skybound

When Chen's right-hand man Clouse, who escaped the Cursed Realm, released a Djinn, Nadakhan, the ninja will have to stop him before he marries Nya and gains infinite wishes. Unfortunately, he stole the Realm Crystal and released the rest of his pirate crew, who helped him build Djinjago from parts of Ninjago. All the Ninja other than Jay and Nya were trapped inside of the Djinn Blade and will count on Jay to save them. Fortunately. Jay's last wish caused everyone, except him and Nya, to forget the majority of the season as well as preventing Clouse from releasing Nadakhan.

***The following events occurred after Jay made his final wish, and thus, happened.***

### *Dark Island Trilogy*

Unwilling to give up his vengeance against the Ninja, Clouse stumbled on the Dark Island and regains his magic. He then released Nadakhan's crew and used them to help him corrupt the Temple of Light which in turn corrupt Ninjago. To do so, they kidnap numerous fishermen, and Lloyd's mother, Misako to retrieve the Dark Matter to corrupt the temple. The Ninja and Master Wu went to rescue them but were briefly separated. Fortunately, Wu uses the Golden Mech to cleanse the Temple from the darkness, causing Ninjago to turn back to normal and Clouse ends up getting banished to the Underworld.

### Day of the Departed

Following the Sky Pirate conflict, Ninjago celebrated the holiday Day of the Departed, with the ninja spreading out across the land of Ninjago to remember their ancestors. Zane remembers his father, Dr. Julien, at Birchwood Forest, Kai and Nya remember their parents, Ray and Maya, at their blacksmith shop, Lloyd and Misako, remember Garmadon at the Corridor of Elders, and Wu remembers his father at the Monastery of Spinjitzu, while Jay spends time with his parents at their junkyard.

In the meantime, Cole was suddenly forgotten by his friends and goes to Master Yang's Haunted Temple to settle his debt with the ghostly master. However, a sinister plot by Yang leads Cole to free the spirits of the ninjas' old enemies from the Departed Realm, including Samukai, Kozu, Cryptor, Chen, and Morro, all of whom possess statues at the Ninjago Museum of History. Seeking revenge, the revived villains spread throughout Ninjago to confront their adversaries.

The ninja defeated their ghostly foes and gathered at the museum, where they were told by Wu and a redeemed Morro of Yang's intentions and how they forgot Cole. The ninja then realized of the danger Cole is in and rushed to aid him, while Morro returns to the Departed Realm at peace.

With the Yin Blade in hand, Yang proceeded to go to the roof of his temple and activates the artifact, using its reality-warping powers to open the Rift of Return. However, Cole confronted Yang, they fought with the master being forced the latter to defend himself with the Yin Blade with success, slicing apart Cole's blade in the process.

However, when Cole's support by his friends powered him up, Cole used his charged fists to attack Yang, who attempted to shield himself with the Yin Blade. Unable to withstand the assault, the Yin Blade was shattered by Cole's attack, and with its destruction and the ending Yin-Yang Eclipse, the Rift of Return started to close as a result. However, a reformed Yang threw Cole through the rift changing him back to a human and the ninja gained a new base in the Temple of Airjitzu.

### The Hands of Time

After the Day of the Departed, the ninja returned to Ninjago Museum of History and discovered that Master Wu and Garmadon confronted two Elemental Masters, after which the ninja decided to stop the Time Twins, but it was too late as they had recollected the Time Blades. Finally they together with Kai, Nya, and Wu traveling to the past, 40 years before, after the defeat of Acronix and Krux. Master Wu sacrificed himself to stop them and Kai and Nya returned to the present to cure their rapidly aging father. Wu then resolved to defeat the Time Twins once and for all.

Realizing that they lost their master, the ninja name Lloyd their new Master. As the new Master, Lloyd had the team to bury the Time Blade and to find their teacher who was lost in time.

### *Way of the Departed*

After Wu was lost in time, the ninja went to search in Wu and split in the beginning to widen their search: Cole and Jay, Kai and Zane, Nya and Lloyd. The ninja decided to look for Wu in different places such as the Library of Domu, the Monastery of Spinjitzu and the Caves of Despair. After looking with no avail, Jay and Cole continued for looking for Wu while the others continued to be the protectors of the realm.

### Sons of Garmadon

One year later, the ninja discovered that a group called Sons of Garmadon are trying to revive Garmadon but in his evil form. They are also reunited with their master, who is revealed to have been de-aged into an infant after his journey through time but is slowly aging back to normal. The ninja also had to protect the Oni Masks, but what they did not have in mind was that Princess Harumi was really the leader of the Sons of Garmadon.

The Sons of Garmadon finally revived Garmadon, who was able to defeat Lloyd with ease and leave the latter powerless. This allowed Garmadon to take control of Ninjago after Kai, Jay, Zane, and Cole, along with Baby Wu, ended up in the Realm of Oni and Dragons when they escaped Garmadon's creation, the Colossus, leading the others to think they were killed.

### Hunted

After being defeated, the ninja have been separated as Ninjago falls under the control of Lord Garmadon. The remaining ninja, Lloyd, and Nya form a rag-tag team with brown ninja Dareth, P.I.X.A.L., and Misako. They were attacked by Garmadon's forces but soon learn that their friends were not killed but were instead teleported elsewhere. They are nearly defeated by the enemy but are saved and gather more allies in old friends to form the Resistance in order to defeat Garmadon and his followers as well as save the city.

The four original ninja (Kai, Cole, Jay, and Zane) along with a rapidly aging Wu must face the dangers of the Realm of Oni and Dragons by dealing with the threats of Dragon Hunters led by Iron Baron, as well seeking to free the dragons and find a way back home to Ninjago.

In Ninjago, Lloyd was able to bring hope back to the citizens of Ninjago and personally opposed his father in the process. This resulted in Garmadon leading an attack on the Resistance's base and having most of his allies imprisoned.

Very soon, the marooned ninja were able to ally with the hunters and the dragons, defeat Iron Baron, and locate the Dragon Armor, and gained new dragons to return back home.

The ninja returned to Ninjago and saved Lloyd's group by using the dragons to rescue them. While Wu and Lloyd fought Garmadon, the ninja evacuated the citizens who realized their saviors returned. The Resistance also broke out to help the ninja in taking back the city. The ninja dealt with the Colossus and with help from their allies defeated the behemoth while Lloyd regained his powers after overcoming his father. In the end, the Sons of Garmadon (except for Harumi and Mr. E due to their deaths) and Garmadon himself were sent to Kryptarium Prison. The ninja were then hailed as heroes by the people for saving them once again.

### March of the Oni

The ninja were honored by the city for their feat of defeating Garmadon, as they were rewarded with a restored *Destiny's Bounty*. They also have rebuilt the Monastery of Spinjitzu and moved back into their old home.

They faced a new problem when one of the Dragon Hunters Faith and Firstbourne, the mother of all dragons, arrive in their realm, revealing a threat is coming. Very soon, darkness emerges from the Realm Crystal, and the city is engulfed. To combat the threat, they reluctantly free Garmadon from prison to help them have a chance against them. While evacuating people from the city, Cole is lost when dark tentacles start to pull him down and Nya accidentally destroys his ropes, causing him to plummet. They regained hope when Nya tells Kai that he can reforge the Golden Weapons out of the armor and fight the Oni since they fear it.

The ninja proceed to forge their weapons, while Cole, who survived the drop, narrowly manages to avoid being petrified in the city and used his drill vehicle to escape the Oni and head for the monastery to help his friends.

As the ninja prepare for their confrontation, the Oni make their way to the Monastery where they fight their enemy. Despite using the Golden Weapons and having a fully powered Garmadon and Wu on their side, the ninja are unable to do much until Cole arrives and helps them with the tides evening for a while, but the Oni were still having the upper-hand. However, Lloyd got the idea to use the Tornado of Creation to fight them off. In the process, Lloyd meets his grandfather in the Grasslands, who praises him on his efforts and gives him the chance to come with him, but Lloyd decided to be reunited with his friends, and only remember it as a dream.

With the battle over and the Oni seemingly vanquished, the ninja commemorate their victory on the Ninjago history mural while Garmadon leaves the monastery to head out on his own path.

### Secrets of the Forbidden Spinjitzu

Six months after the fight with the Oni, the ninja were able to enjoy a time of peace, but became so lazy that Wu easily tossed them aside in training.

The ninja resorted to traveling around the city to find a sense of adventure but nothing came up because most of their enemies are either arrested, in the Departed Realm, or in hiding. As a result, they travel to the Desert of Doom with explorer Clutch Powers. Unknowingly, the ninja accidentally release the Serpentine sorceress Aspheera, who steals Kai's power and leaves them trapped.

However, the ninja were able to escape the pyramid and learned that Aspheera was after someone known as the "Treacherous Deceiver," who was later revealed to be Wu.

The ninja then later confronted Aspheera at the hangar bay and fought against her forces. After a long battle, Zane was able to defeat her, but at the cost of him being banished to the Never-Realm to save Wu from the blast.

After the ninja went to the Never-Realm, Lloyd and a Formling named Akita went to the Castle of Ice to rescue Zane from the Ice Emperor while the others stayed behind to defend the Ice Fishers, but only for Lloyd to realized that the Ice Emperor was actually Zane, who became the Ice Emperor by being corrupted by the Forbidden Scroll and had his memories lost by Vex.

In order to free Zane from Vex's manipulation, Lloyd forms another Resistance with Kataru and Grimfax, but only for the Resistance to be quickly defeated by the Blizzard Samurai. However, when Lloyd was mocked by Vex, Zane regained his memories and freed the realm from its eternal winter, allowing the ninja to be reunited and return to Ninjago and have Vex exiled far away for his tyranny.

### Prime Empire

After helping the police arrest the Mechanic for stealing a motherboard, the ninja investigate his base where Jay finds an old arcade game called *Prime Empire*, which the motherboard was needed. After turning it on, he had inadvertently sent a shockwave that turned all the video games into *Prime Empire* and plays it before entering it.

After investigating the game and learning more about its history and creator, the rest of the ninja, minus Zane, enter *Prime Empire* and reunite with Jay. They receive new suits and weapons before heading out to achieve the Purple Key-Tana, one of three keys they need to escape unlock the final arcade cabinet and enter the Temple of Madness.

Allying with Okino for a brief amount of time, they get the Purple Key-Tana. After entering a dance competition and winning 500 credits to enter the Speedway Five-Billion, they win, but at the cost of their new friend Scott, as well as Cole and Kai.

Eventually, after many trials, Jay emerged as the last ninja standing. However, Jay, with the help of Zane, P.I.X.A.L, and Wu, was able to get Unagami and Milton Dyer to make amends and rescue the trapped players along with the NPCs. As a result, the remaining ninja were released from the game as well.

### Master of the Mountain

After the ninja and Wu were invited to by King Vangelis, they traveled to Shintaro to celebrate Princess Vania's birthday. However, when Cole met a purple creature that had his mother's necklace, he and Vania discover an army of skeletons forcing two warring tribes to mine Vengestone in the Dungeons of Shintaro for the evil Skull Sorcerer.

The ninja were separated through the perilous mountain where they each work to end the conflict of the tribes. Meanwhile, Cole discovers that King Vangelis is really the Skull Sorcerer and that he was responsible for everything happening in the Dungeons. Not wanting his plans to be exposed, he banished Cole and Wu, who were aided by Vania.

The other ninja soon discover that Vangelis is the villain and he imprisoned them and the other tribes. Vangelis was preparing to execute the ninja to destroy the remaining glimmer of hope that the Geckles and Munce have. Cole's group soon encounters a group of wanderers and they travel the mountain. Cole discovered the Blades of Deliverance that used to belong to his mother. Armed with weapons, Cole saved his friends and confronted Vangelis. After a fierce duel, the blades were destroyed after they turned out to be powerless. Despite all this, Cole had managed to unlock the ability to use the Spinjitzu Burst, destroying the Skull of Hazza D'ur as well as disassemble the Re-Awakened and the resurrected Grief-Bringer. Vangelis was defeated and apprehended by his daughter and former followers for all of his crimes. So as of now, the ninja and Wu are heading off to their next adventure.

### The Island

After weeks have passed, the Ninja have discovered that Misako's membership to the Explorer's Club had expired due to her and Wu being missing for weeks in a mysterious island. So they travel with a survivor named Twitchy Tim to the island to investigate. Once they arrived, the Ninja ended up being ambushed by a bunch of moving statues and are placed in a cell along with Wu, Misako, Clutch Powers, and his interns by a ancient tribe known as the Keepers. The keepers were just trying to protect an ancient storm amulet given to them by the First Spinjitzu Master in order to keep the storm spirit, Wojira, from waking up and are giving away any valuables they have including Jay to what appears to be her at first.

But the Ninja eventually discover that the Wojira that the keepers saw is really a ship owned by Ronin and the thugs that he supposedly captured to get all the treasure he wanted. Luckily, they managed to save Jay and a fight commences. Ronin tries to get away but Twitchy, motivated by Lloyd to face his fear, stopped him just in time and Ronin and his gang are placed in the Keepers' cell.

Afterwards, the leader of the Keepers, Mammatus, apologizes to the Ninja for the mishap but they quickly forgive him and return home. But Lloyd had began to wonder whether or not Wojira is still around.

### Seabound

During an attempt to stop a criminal named Miss Demeanor, Nya's powers spiral out of control. The Ninja turn to Wu for some advice as to how to resolve this and the only option they have is to call Maya as she was the Elemental Master of Water before Nya much to the latter's annoyance.

Later, Zane and P.I.X.A.L. find out about the energy bursts disrupting anything linked to water, forcing Nya, Jay, Zane, P.I.X.A.L. ,Lloyd and unknowingly Maya to get to the Tartarus Trench. After being sunk by Maaray Guards, the Ninja must go underwater to the source of the energy burst and harness it but Nya and Maya see Wojira, Kalmaar and what has been causing the energy bursts. Unfortunately, Nya and Maya are revealed and captured by the Merlopians. Jay, knowing the consequences for zapping the Hydro Bounty’ battery, still did it and got the ship up & running to save Nya and Maya, who are already making their escape. The two groups eventually meet up again but are captured by Maaray Guards and are taken to a upset Trimaar. They explain the actual events to Trimaar shortly before being killed by his son. Kalmaar has the Ninja framed as fugitives of Merlopia. They escape with Benthomaar, who is aware of how the king was killed and start their travel to the Island of the Keepers. They find out that the amulet the Keepers have is fake and go and warn Cole of the situation, but is shortly stranded by Kalmaar.

The Ninja in Ninjago City meet Kalmaar in the Explorer's Club and they battle for the Storm Amulet, which Kalmaar ends up winning and he awakens Wojira but is stopped by Nya who merged with the ocean to defeat Wojira, unfortunately Nya departs from the Ninja to be with the ocean, and a memorial is held in her honor at the Monastery of Spinjitzu.

### Crystalized

Within a year of Nya's sacrifice, Kai, Jay and Lloyd left the team to deal with grief their own ways while Zane had turned off his emotion meter. Learning that a new group of ninjas have risen to take their place, Vengestone was still being smuggled, and Mayor Trustable calling them destructive, Cole and Zane decided to bring the team back together. But while Kai was easy to bring back, Jay and Lloyd refused, until they discover a candlelight vigil in Nya's honor, inspiring them to return. After being defeated by Miss Demeanor and saved by the New Ninja, who call them old timers, this leads to Kai and Jay arguing, until Nya appeared and told the team she must have her powers removed to return to normal.

When the mayor refused to release Aspheera from Kryptarium Prison, Kai, Zane and Lloyd break her out while Jay and Cole steal her staff from Borg Tower, only to find it gone.

Managing to intercept the vans containing it, which also led to their identities exposed, the Ninja were able to have Aspheera turn Nya back to normal, but are arrested in the end, and sentenced to five years in Kryptarium. While enduring prison life, the Ninja learn of a new villain called the Crystal King recruiting their old enemies to form a council, and, with Nya and Dareth's help, escape and attempt to infiltrate the council. But, the latest recruit, The Mechanic, blows Lloyd's cover, which leads to him discovering the Crystal King's messenger is Harumi, who was resurrected by the Crystal King, who is actually the Overlord, by swearing her allegiance to him. Harumi soon manipulates Lloyd into unleashing his dormant Destruction powers by killing the Ninja, unaware that they seeked refuge in a BRTM-12 train. The council then steals the Golden Weapons and destroy the monastery.

After being rescued by Nya and stealing back their impounded vehicles, the Ninja manage to retrieve Lloyd from Primeval's Eye, where they try to fight back against the Overlord and his Crystal army while Lloyd and Wu reunite with Garmadon, who had been hiding out in Vinny Folson's apartment before witnessing him using Oni form against some crystal warriors, inspiring Wu to have Garmadon teach Lloyd to unlock his own Oni form.

As the battle continues, Nya also begins to rediscover her powers. Briefly separated after a failed strike, the Ninja reunite at the newspaper warehouse, where they learn of Dragon Form, which can turn the tide on the battle, but are unable to achieve it, until many allies, past and present, came to their aid, allowing them to unlock Dragon Form, reclaim their Golden Weapons and defeat the Crystal Council. Lloyd and Garmadon attempted to fight against the Overlord, alongside a vengeful Harumi, who discovered the truth about her biological parents' death. With Lloyd resisting his unlocked Oni form, the original Ninja use their Golden Weapons to combine them into a dragon and defeat the Overlord, at the cost of their powers.

A week later, the Ninja, along with Garmadon, the redeemed Harumi, their allies, the New Ninja and former enemies, work on rebuilding the monastery.

### *Quest for the Lost Powers*

Not long after the monastery was rebuilt, the original ninja went on separate journeys to regain their powers. Kai regains his while on his quest to defeat Fire Fang, Zane regains his while going through his memory and forgave his Ice Emperor self, Cole regains his while defending a farming village, and Jay regains his while exploring with Unagami.

### The Merge

When Wu discovered scrolls about a disaster that would combine all realms, it came earlier than expected. While it happened, the ninja move to rescue the people caught up in it before heading for the source itself, only for it to close up and separate the ninja.

Lloyd woke up at the monastery, which had mysteriously changed. Kai woke up on an unknown island, managed to recover the *Bounty* and reunited with Lloyd before leaving to study and map out the combined realms. Nya woke up somewhere that led her to the Kingdom of Madness and reunited with Kai. Zane was put in a stasis pod in the Monastery of Imperium. Jay woke up in a place called the Administration. And Cole woke up in the Land of Lost Things.

### *Dragons Rising*, Season 1

Many years after the Merge, Lloyd went to the Crossroads, a town created for those who lost their homes and families, where he spots a ninja on a bridge protecting a baby dragon from the Claws of Imperium, before they, along with another companion were captured.

Lloyd comes to their rescue to see it was Arin, a boy he once saved and was using his old mask he had lost during the Merge, who was the ninja on the bridge, as well as a fan that learnt Spinjitzu all by himself. With advice and encouragement from Riyu's Matriarch, Lloyd took him and his friend Sora, the Elemental Master of Technology, as his first students.

Reuniting with Kai and Nya in the Kingdom of Madness, they end up coming across the Cloud Kingdom and close two MergeQuake rifts with help from the new Master of Wind before Nya stayed to find the solution to stopping the MergeQuakes.

After failing to rescue a dragon, Lloyd, Arin and Sora sneak into Imperium to disable an old invention of Sora's, who lived there before the Merge, during which Lloyd met another Elemental Master named Wyldfyre, who was raised by a dragon before they work together to free the captive dragons.

While searching for a way to escape, the Monastery of Imperium arose with Kai, Nya, and Zane joining the fight before they escape the city through it.

Eventually, they come across the Temple of the Dragon Cores, where they learn that in order to stop the MergeQuakes, they must unite the three Dragon Cores and immediately split up to search for them while Zane stayed to research the portal gate that led them to the Imperium Monastery, as well as bring in Arin and Sora's friend, Alfonzo Frohicky, to maintain the monastery in their absence.

Lloyd and Arin went to the Mother Garden, making a brief pit stop to help algae farmers reclaim their village from mind controlled Merlopian pirates, and discover from the Mucoids that Rapton tried to steal their Dragon Core. Despite their effort to spare him, Rapton double-crosses them, only to be taken out by agents that came from the Administration, who take the core for themselves. Kai and Wyldfyre went to the latter's home of the Wyldness, running into some complications, due to Wyldfyre's pranks, they're forced to clean up the Lava-Tides' village from Wyldfyre's past antics before Dorama showed up to claim the Dragon Core, but the two escape, although Heatwave was wounded in the escape. Nya, Sora, and Riyu went to the Pinnacle of Crystals, only to find the location where the Dragon Core normally is was empty, and Nya ends up triggering a trap that sends Howlers after them, but are saved by Sora the dragon's old acquaintance, a Djinn named Arrakore, who was in exile following Djinjago's destruction. But after eliminating the Howlers, Arrakore gives them an arrow that would guide them to the core, leading them to the Land of Lost Things, where they come across Cole, who was now a golem before discovering the core was powering a device keeping a creature called the Sweeper back, until Dr. LaRow managed to steal it. When it came to attacking Imperium, Cole stayed behind before following a strange light whispering his name. While healing Heatwave, Kai taught Wyldfyre how to keep calm before discovering the core they managed to grab was a fake. Lloyd and Arin find themselves in a realm called The Administration, where they're guided by someone handing them notes that lead them to discover it was Zane, who was taken by their Agents and learn they plan to destroy the core the Agents took. Managing to retrieve it, Lloyd, Zane, and Arin escape, unbeknownst to any of them, leaving Jay behind.

Infiltrating Imperium, they find the Imperium Teen Resistance Force, who intend to expose Beatrix for her deception, which they succeed. However, using the two Dragon Cores and one made from the energy of the Source Dragon, Beatrix began opening MergeQuakes, Kai, Wyldfyre, and Riyu being caught in some, until Sora, unlocking her True Potential, destroys it and Arin sends Beatrix into a MergeQuake before a storm occurs.

Then, using all three cores, Lloyd was able to stop the MergeQuakes, bring the world back in balance and returning those who were caught in the MergeQuakes, including Kai, Wyldfyre, and Riyu before Lloyd uses them to free the Source Dragon.

## Ages of the ninja

The ninjas' ages are not specified.

**Ninjago:** **Masters of Spinjitzu:** The ninja were in their teenage years during the original series, with the exception of Zane, who is decades older but was built to have the appearance of a teenager. Lloyd became physically around the age of his older friends due to the effects of the Tomorrow's Tea, but he is still chronologically the youngest of the team due to having originally been a pre-teen. Zane is over 100 years old, due to spending around six decades as the Ice Emperor in the Never-Realm.

While the ninja were officially teenagers during the original series, with Jay referring to them as "grown-up teenagers" in "The Gilded Path," their specific ages and the amount of time that passes between seasons were kept vague for the purpose of keeping them in an age-range that is young and relatable to the show's target audience. Furthermore, Tommy Andreasen noted that the age of the ninja is not specific and is up to the viewer's interpretation. According to the Hageman Brothers, the ninja's aging is comparable to Bart Simpson's, whom is often used as an example of the phenomenon of cartoon characters remaining the same age despite the passage of time. Similarly, Tommy Andreasen compared the ninja's aging to that of Batman, stating that "time is less of a factor" in fiction. Tommy Kalmar refers to the group as "teen ninjas" in his 2022 "What is Ninjago?" video on LEGO.com, meaning they were still officially teenagers during the events of Crystalized.

**Ninjago: Dragons Rising:** Sometime after Crystalized, the Merge occurs and the story skips ahead years later. Ninja students Arin and Sora are teenagers, and Wyldfyre likely is as well, since she was also a child during the Merge. While the amount of time is unknown, enough years have passed that the ninja students grew up from children with short legs to teenagers with normal-sized legs, instead of the medium legs which pre-teens/young teenagers usually have in LEGO post-2018. This may imply that the older six ninja are now young adults in their early 20s instead of late teens, but as mentioned above, the creators do not specify ages

## Trivia

* The name "ninja" is not treated as a proper name when Wu refers to the team in his writing in the *Dark Island Trilogy* and *The Book of Spinjitzu* or when it is written in *Pythor's Revenge*. However, the word is treated as such, being written as "Ninja," on several other occasions, such as in earlier books, often on the website, and in the March of the Oni character posters. Official episode descriptions for the series have written the word both ways.
* The "official order" of the ninja seems to be Kai, Jay, Zane or Cole, and Lloyd or Nya.
	+ The intro in seasons 1 and 2 has Kai, Jay, Zane, Cole, Lloyd (when introduced), and Nya.
	+ The Character Card statistics are ordered as Fire (Kai), Lightning (Jay), Earth (Cole), and Ice (Zane).
	+ Books such as the *Character Encyclopedia* and *The Visual Dictionary* order their pages for the ninja as Kai, Jay, Cole, and Zane.
	+ On the Wu-Cru missions site, the ninja are ordered as Kai, Jay, Cole, Zane, Nya, and Lloyd.
	+ The intro for Ninjago: Decoded is ordered as Kai, Jay, Cole, Zane, Nya, and Lloyd.
	+ Zane's narration in "Legacy" is ordered as Kai, Jay, Cole, Zane, and Nya (Lloyd is introduced later).
	+ Tommy Andreasen's drawings of the ninja in 2018 were ordered Kai, Jay, Zane, Cole, Lloyd, and Nya, though it's possible the order in this case was mostly a coincidence.
* The ninja's phone number in Season 1: Rise of the Snakes was 555-122091-1.
* Six of the ninja (and Master Wu, Misako, and P.I.X.A.L.) have changed their physical appearances in the show.
	+ Jay, Kai, Zane, and Cole turned into kids in "Child's Play," but they turned back into teenagers shortly after.
	+ Lloyd was a child until he threw a jar of Tomorrow's Tea at the Grundal 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." In "The Mask of Deception," he gains a cloak that lets him turn into his human-like form. However, he has never used this ability since Secrets of the Forbidden Spinjitzu, but uses it again in "The Benefit of Grief" and (in his damaged state) "Return of the Ice Emperor."
	+ Cole was a human 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, though it has faded as of Season 8 and only shows when he performs his Earth Punch.
	+ Nya's lips are no longer red from Season 6 onward. She had a brief infusion with the Endless Sea from "Nyad" to "A Painful Promise."
	+ In Season 8, all the ninja have different appearances, similar to their movie counterparts. See here for more information.
	+ After being touched by the Reversal Time Blade, Wu has become a baby. Throughout the eighth and ninth season, Wu grew from a toddler, child, young teen, teen with mustache and goatee, then got his straw hat, and finally back to his old form.
	+ Misako's white streak of hair was absent for The Hands of Time and then appeared again in Season 8 more prominently than previous seasons.
	+ P.I.X.A.L. originally had the same hairpiece as Tox, but in Season 8, it was changed to a silver variant of Nya's Season 8 hair.
* Jay, Arin, Sora, and Wyldfyre are the only ninja to have never died.
	+ Zane, Kai, Cole, and Lloyd died after being encased in gold by Nadakhan, but were revived after he was hit by the Tiger Widow venom.
	+ Nya was killed by the Tiger Widow venom in "The Way Back," but was revived as a part of Jay's final wish.
* Jay was the only ninja to appear in every *Ninjago* episode until "The News Never Sleeps!" and "Never Trust a Human" aired, with Cole and Nya following behind him. But Nya has one more appearance than Jay, since he didn't appear in the second and third episodes of Prime Empire, with Cole behind him by one appearance.
* All of the ninja (and Master Wu) have traveled to another realm, including after the Merge.
	+ The original four (and Master Wu) have been to the Underworld and Realm of Oni and Dragons.
		- Nya also went to the Underworld as well but was not a ninja at the time.
	+ Wu traveled to the Realm of Madness to search for Garmadon.
		- Kai, Lloyd, Nya, Arin, and Sora traveled there after the Merge.
		- Zane traveled there by being taken to The Administration.
	+ All the Ninja, except Wyldfyre, have traveled to the Cloud Kingdom, with Kai and Lloyd having been twice.
		- Lloyd was possessed by Morro the first time he visited.
	+ Due to his fight with Morro, Lloyd is the only one to go to the Cursed Realm and Chima. This causes Lloyd to be the one with the most travels to other realms.
	+ Kai, Jay, Cole, Lloyd, and Nya have traveled to the Never-Realm in order to rescue Zane after he was banished there.
		- This also marked the first time where all six ninja (at the time) travel to another realm.
	+ Kai, Zane, Lloyd, Nya, Arin, and Wyldfyre traveled to Imperium.
		- Sora lived there, prior to the Merge.
		- Cole lived in the Land of Lost Things, which is located in Imperium, after the Merge.
	+ Kai traveled to the Wyldness.
		- Wyldfyre was stranded and grew up there, prior to the Merge.
* Five of the current ninja have traveled to space.
* After Cole's physical reformation in "Day of the Departed," Zane once again becomes the only biologically non-human on the team. Lloyd is mostly human, but also part Oni and Dragon, because of his ancestry.
* At one point, the Hageman Brothers had an idea to make each ninja have a distinctive physical attribute in addition to their elemental powers, following how Zane was a titanium robot and Cole was a ghost. They were thinking of Jay being a master of disguise and Kai becoming a rock fire lava monster when he got angry. However, they're glad they didn't go with this idea in the end.
* All ninja have at one point not wore every different suit shown in the show.
	+ Kai did not have his Scuba suit, due to not going down Tartarus Trench.
	+ Jay did not have his Merge Suit, due to being in the Administration.
	+ Cole did not have his Prime Empire avatar attire, due to not purchasing it, and his Scuba suit, due to not going down Tartarus Trench.
	+ Zane did not have his Digi-Robe, due to not entering Prime Empire.
	+ Lloyd only got up to his ZX suit, due to being a minor antagonist before joining the ninja.
	+ Nya only got up to her Deepstone suit, due to being Samurai X. She did not have her Prime Empire avatar attire, due to not purchasing it.
	+ Arin, Sora, and Wyldfyre did not have any suits prior to their debuts as ninja.
* Technically, the older ninja have the title "Master," as they are all Masters of an element. This was shown in "The Corridor of Elders," when Arcturus identified Lloyd as "Master Lloyd."
	+ As a ninja, however, Lloyd is the only one who has achieved the rank of Sensei/Master.
* At some point, all members of the team (and some allies) have turned against their team and been reverted back:
	+ Garmadon was revived in Sons of Garmadon and became evil again but has since tried to regain his humanity starting from March of the Oni.
	+ Lloyd 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.
	+ Kai was briefly corrupted by the Staff of Elements and nearly attacked Lloyd and Skylor.
	+ Ronin was forced by Morro to betray the ninja in "The Crooked Path," hired by the police to capture the ninja in "Public Enemy Number One," and terrorized the Keepers in The Island.
	+ Misako was controlled by Bansha in "Grave Danger" and was corrupted by Dark Matter in the *Dark Island Trilogy*.
	+ Nya was possessed by Delara.
	+ P.I.X.A.L., as Samurai X, was controlled by the Quiet One during Season 8 before Zane killed the spider thus freeing her.
	+ Wu and Lloyd were briefly corrupted by a Scroll of Forbidden Spinjitzu.
	+ Zane's memories were erased by Vex, who manipulates him into being corrupted by the Scroll of Forbidden Spinjitzu and become the Ice Emperor, started the Long Winter, and held Lloyd hostage. However, Zane regained his memories when Vex said "protect."
	+ Jay and Kai fought each other after the latter knocked over the former's glass of water in "The Shape of Nya", but halted upon Nya's return.
	+ Sora reluctantly activated her Photacs to fight for the Claws of Imperium against the ninja, but disabled them while escaping them.
	+ Cole attacked Nya, Sora, and Riyu for chasing after the children living in the Land of Lost Things as a golem, but stood down upon recognizing Nya.
	+ Jay was made manager of realm assignment in The Administration and still remains there.
* Although Lloyd is the leader of the team, every ninja aside from Nya, Arin, Sora, and Wyldfyre has taken on the role of the leader, specifically, early on in Possession when Lloyd was possessed.
	+ It was previously assumed that Cole was the leader, but this was never officially part of the show. This was referenced in "The Two Blades" when Vania assumed Cole was the leader and in the Ninjago honest trailer when the narrator said "we were led to believe" Cole was the leader. It was also mentioned in the Character Encyclopedia and its expanded edition. There was no official leader of the team prior to Lloyd's transformation into the Golden Ninja, other than Wu.
* After Rebooted, the ninja (except Nya) could only harness their elemental powers while dependent on their leader, Lloyd, because he shared his Golden Power between them. This was shown when they lost their powers when Morro possessed Lloyd in "Winds of Change."
	+ However, when Lloyd lost his powers in "Big Trouble, Little Ninjago," the other ninja still had theirs. Tommy Andreasen implied this may have been due to the passage of time and Lloyd's growth causing the ninja's powers to become more independent from him.
* Five of the ninja are the only Elemental Masters that have the main elements in Ninjago.
	+ Nya's element, Water, is a secondary element.
	+ Sora and Wyldfyre's elements, Technology and Heat respectively, originated during the Merge.
* Four 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, however, he uses silver more often.
	+ Cole was black but now alternates between gray and brown whenever the ninja wear predominantly black gi.
	+ Nya was red, then alternating between azure, maroon/dark red, and dark gray.
* Six of the ninja have seasons or TV specials 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, Season 6, the Prime Empire Original Shorts, and Season 12.
	+ Zane was the focus of Season 1 and Season 3.
	+ Cole was the focus of Season 1, "Day of the Departed", and Season 13.
	+ Lloyd was the focus of Season 2, Season 8, and Season 15.
	+ Nya was the focus of Season 7 and Season 14.
* Five of the Ninja have traveled to the past. Kai is the only one who has traveled to the past thrice.
	+ Kai, Cole, Zane, and Jay went to the past in "Wrong Place, Wrong Time."
	+ Kai, along with Nadakhan, in "Misfortune Rising."
	+ Kai, Nya, and Master Wu in "Lost in Time."
	+ Zane was sent to the Never-Realm, around 60 years into the past in "Vengeance is Mine!."
* 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.
	+ Due to Jay losing his memories in the Administration, Nya is currently the only character to remember Skybound.
* Most of the ninja have their own signature color.
	+ Kai's signature color is red.
	+ Jay's signature color is blue.
	+ Zane's signature color is white.
	+ Cole's signature color is black.
	+ Nya's signature color changed between maroon, azure, and gray.
	+ Lloyd's signature color is green.
	+ Arin's signature color is orange.
* Six of the 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 (and later revealed to be his ancestry).
* Six of the 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), until Season 11.
	+ Kai's signature weapon was a single katana, then a pair, and now a single golden katana.
	+ Jay's signature weapon was a pair of nunchucks, and now a golden kusarigama.
	+ Zane's signature weapon switched between shurikens and a bow and arrow, and then back to shurikens.
	+ Cole's signature weapon was a scythe, then a hammer, and now a golden one.
	+ Nya's signature weapon was a boomerang, then briefly a fan, then a spear, and now a golden spear.
	+ Lloyd's signature weapon was a pair of katanas, then a gray-silver sword, and now a golden one.
* Zane is the oldest ninja of the team, as he was created forty years ago. Although as of Season 4, he has a new body, technically making him no longer an "outdated model."
	+ As of Season 11, Zane is even older than the other ninja after spending decades in the Never-Realm.
* Prior to Arin, Sora, and Wyldfyre joining the ninja as students, Lloyd was the youngest, though was aged physically to be the same age as his friends.
	+ However, in Season 6, when Lloyd aged into an old man, he was temporarily physically the oldest ninja of the team before reverting back to a teen.
* Most of the ninja have had a love interest which was 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 in Season 6 and remain a couple. They soon Yin-Yang promise in Season 10.
	+ Kai has an interest in Skylor, the daughter of Chen, in Season 4: Tournament of Elements. They officially got together at some point before "Quest for the Lost Powers."
	+ Zane had an interest in P.I.X.A.L. in Season 3 and they have remained together since.
	+ Cole had an interest in Nya during Season 3 which caused a rivalry between him and Jay until she chose Jay.
	+ Lloyd had an interest in Harumi in Season 8: Sons of Garmadon, but she was later revealed to be evil. Although she seemed to have only been using him, he seemed saddened when she died in Season 9. He was in complete shock when she revealed herself to him in Season 15, before admitting he tried to look for her after Garmadon's defeat. She redeemed herself when she discovered the Overlord was responsible for her parents' death, and gave him a friendly wave at the end of "Roots."
* From Season 8 to Season 10, six of the ninja had their names and signature colors on their weapons. As of Season 11, their weapons are now gold and just have their signature colors.
* As of "A Painful Promise," most of the ninja had lost their powers at one point.
	+ Sora's could only be activated by Riyu until she achieved her True Potential.
	+ Arin does not possess an Elemental Power.

* Lloyd and Jay are the only ninja to have confirmed surnames. Zane's surname is most likely Julien, though it is not confirmed. Kai and Nya's surname was considered "Smith" behind the scenes, though this is not necessarily canon to the show.
* According to Wu in Season 11, the first ninja were originally monks living in the mountains of Ninjago. As predators killed the monks, they had to become faster, stronger, and more cunning in order to survive, eventually evolving into ninja.

* Lloyd, Cole, Nya, Jay, and Zane are so far the only ninja that at one point were responsible for orchestrating most major events.
	+ Lloyd freed the Hypnobrai, the Fangpyre, and Pythor prior to becoming a ninja in Season 1.
	+ Lloyd inadvertently released Morro from the Cursed Realm in Season 4, and gets possessed by him in Season 5.
	+ Cole set Samukai, Kozu, Cryptor, Chen, and Morro free from the Departed Realm while set on revenge against Yang in "Day of the Departed."
	+ Nya and Jay solved the puzzle that set Aspheera free from her entombment in Fire Chapter of Season 11.
	+ Zane trapped the Never-Realm in an eternal winter upon Vex erasing his memories, overthrowing Grimfax, and establishing himself as the Ice Emperor in the Ice Chapter of Season 11.
	+ Jay resurfaced *Prime Empire*, trapping over 800 players including himself in Season 12.
* Lloyd, Jay, Cole, and Zane are currently the only ninja that either know or have performed Spinjitzu, Airjitzu, and Forbidden Spinjitzu at some point.
	+ Kai and Nya know and have performed Spinjitzu and Airjitzu multiple times, yet never used Forbidden Spinjitzu. (Kai held the scroll once, but couldn't use it because he had no powers yet due to Aspheera taking them away)
	+ Wu knows and has performed Spinjitzu and has used Forbidden Spinjitzu, yet does not know Airjitzu. While he uses Airjitzu in the *Dark Island Trilogy*, it has since been confirmed to be a mistake and that Wu does not actually know Airjitzu.
	+ Like Wu, Garmadon knows Spinjitzu and has used Forbidden Spinjitzu, yet does not know Airjitzu.
	+ P.I.X.A.L. briefly used Spinjitzu alongside Zane and did have a noticeable reaction to the Scroll of Forbidden Spinjitzu, yet never used Airjitzu.
	+ As the Spinjitzu Burst is a martial art that can be achieved by any Elemental Master if surrounded by their element, Cole is the only member of the team to use all four martial arts.
		- Tommy Andreasen did mention, however, that the theory of Nya unlocking her Spinjitzu Burst in "Curseworld, Part II" to destroy the Preeminent has lead the team to reconsider or not if this was her form of the burst. This has not yet been confirmed, however.
	+ Arin only knows Spinjitzu, which he learnt by himself, including Object Spinjitzu, which he inadvertently invented.
	+ Sora and Wyldfyre don't know any of them.
* Wu, Kai, Jay, Zane, Cole, Nya, Lloyd, and P.I.X.A.L. are the only characters in the *Ninjago* series to appear in every consecutive installment since their initial introduction.
	+ Wu, Kai, Jay, Zane, Cole, and Nya have all appeared in every season since their introduction in the pilot episodes, as well as the *Dark Island Trilogy* and "Day of the Departed."
	+ Lloyd has appeared in every season since his introduction in Season 1, as well as the *Dark Island Trilogy* and "Day of the Departed."
	+ P.I.X.A.L.'s streak was broken when she did not appear in Season 1 of Ninjago: Dragons Rising, after appearing in every season since her introduction in Season 3, as well as the *Dark Island Trilogy* and "Day of the Departed."
	+ Garmadon's streak was broken when he did not appear in Season 6, after appearing in every season since his introduction in the pilot episodes.
	+ Dareth's streak was broken when he did not appear in Season 13, after appearing in every season since his introduction in Season 2, as well as the *Dark Island Trilogy* and "Day of the Departed."
	+ Misako's streak was broken when she did not appear in Season 11, after appearing in every season since her introduction in Season 2, as well as the *Dark Island Trilogy* and "Day of the Departed."
* The ninja's future reflections, apart from Cole and Lloyd, are shown in the ice labyrinth in Season 5. While it would seem the cast's change in appearance after the movie means these visions are no longer accurate, Tommy Andreasen has implied they may still look like this in the future.
	+ When asked about how the future reflections didn't seem to compare to the Season 8 designs, he replied "That reflection is like 50 years into the future … season 8 is not."
	+ When someone said that the timeline was altered by Wu in Season 7, he said "No he didn't. We did a design update. Shows do that and we will do so again sometime."
	+ Whatever may happen in-universe, the appearances of the ninja will most likely not revert to their original designs within the show itself.
* Cole is the only ninja whose future or older self has not been seen, as everyone but he and Lloyd had future reflections in the ice labyrinth, while Lloyd temporarily became an old man in the second half of Skybound.
* Some of the ninja get more of a spotlight in the sets than others:
	+ After the 2019 *Legacy* spinners, Kai has appeared in all six collectible set series (Spinjitzu Slam, Arcade Pods, Spinjitzu Burst, Epic Battles, Spinjitzu Training, and Dragon Power), Lloyd and Jay have appeared in three, Zane and Cole have appeared in two, and Nya has appeared in none.
* Tommy Andreasen does not think whether the ninja have different heights or not is relevant to the story. He later said that their heights are "Average."
	+ An image by PenPlays on Twitter show in a line up of the ninja that they appear to be around 6' 5".
* Kai, Cole, Arin, Sora, and Wyldfyre are the only ninja who have not been shown to cry or shed a tear at any point, the instances of the other ninja being Zane in "Tick Tock," Jay in "Home" (as a tear of happiness), "The Way Back," and "The Turn of the Tide," Lloyd in "Big Trouble, Little Ninjago," and The Spider's Design," and Nya in "The Fall," "Endings," and "Nyad."
* The ninja have distinctive eyebrows in order to easily identify them when they have their masks on.
* The ninja's names were chosen "Quite carefully ... and with legal checks to avoid any infringements."
* Six of the ninja had at least one episode where the ninja learns secrets about one of his or her parents. Zane remembers his father in "Tick Tock" and learns he is alive and reunites with him in "The Last Voyage," Garmadon tells Lloyd about his past in the Serpentine War in "Spellbound," Jay learns he was adopted and his father was Cliff Gordon in "Misfortune Rising," Kai and Nya find their parents and learn why they disappeared in "Pause and Effect," and Cole learns about his mother unlocking the Spinjitzu Burst in "Masters Never Quit."
	+ Arin lost his parents in the Merge in "The Merge: Part 1," and briefly saw them in a MergeQuake rift in "The Power Within."
	+ Sora ran away from her parents, which is seen in a flashback in "Return to Imperium," and briefly reunited with them before disowning them in "The Power Within."
	+ Wyldfyre's parents were never mentioned as she grew up in the Wyldness.
* Although originally the ninja used pajamas often during sleep, in newer seasons they are already sleeping in their gi, due to simpler animation because of modest budget (or in-universe because it allows them to leap into action more quickly).
* Tommy Andreasen has stated that he believes any of the ninja could turn evil given the right set of circumstances.
* According to Tommy Andreasen, if the ninja had YouTube channels, Jay would make game videos, Kai would give bad dating tips, Nya would make self-improvement videos, Cole would do "the joys of cake," and Zane would make Brent Miller parody videos.
* In Secrets of the Forbidden Spinjitzu, Master of the Mountain, The Island, and Crystalized, the story of the ninja starts in the Monastery of Spinjitzu. According to Tommy Andreasen, it's because "We like our beloved characters to rest a bit. Who would deny them that after all their hard work?"
* The ninja do not have official birthdays. However, Jay and Lloyd's birthdays seem to take place not long after The Hands of Time, since within the season, they both received early birthday gifts but did not celebrate their birthdays.
* In Ninjargon, "ninja" means one who protects.
* During "Stiix and Stones," Cole, Kai, Jay and Zane had a total of less than two hundred in cash. At present, however, their assets are unknown.
* Zane, Nya, Arin, Sora and Wyldfyre are the only Ninja to have never been seen without torso coverings.
* At one point, the ninja separated, but reunited or remain separated.
	+ Zane inadvertently left the team when his original body was destroyed before rebuilding himself and came back after the Tournament of Elements.
	+ Kai, Jay, and Cole left the team after Zane's assumed death before being brought back together by Lloyd, which led to the Tournament of Elements.
	+ Nya left the team after merging with the Endless Sea before being removed of her powers by Aspheera, and later regained them.
	+ Kai, Jay, and Lloyd left after Nya's departure before returning upon seeing the Candlelight vigil for Nya.
	+ Kai, Jay, Zane, Cole, and Nya left the team, due to the Merge. Only Kai, Zane, and Nya returned while Jay stayed at the Administration (unbeknownst to the other ninja) and Cole stayed in the Land of Lost Things.
* Arin, Sora, and Wyldfyre are the only ninja not to have a criminal record.
	+ Nya had one as well, although it was erased by Jay's final wish.
* When asked where the ninja take money, Tommy Andreasen replied, "We can say they are funded by Borg if that eases you."
* P.I.X.A.L. is the only official members of the team who is not a ninja.
* P.I.X.A.L. and Arin are the only official members of the team to not harness an elemental power.
* P.I.X.A.L., Sora and Wyldfyre are the only official members of the team who do not know Spinjitzu.
* Apart from Nya, who wasn't a ninja at the time, the ninja did not have their hair pieces in the sets until 2014 in the Rebooted wave as part of their Techno gi designs, even though their hair was seen in the TV series (even more than their masked appearances) since 2011. Before that, Jay, Cole, and Zane's hairpieces existed in other LEGO themes, while both of Lloyd's existed but not in blond, and Kai's did not exist at all, as it was designed by WILFilm for the show. Young Lloyd's hair did not physically exist until it was released in 71741 Ninjago City Gardens, almost nine years after its first appearance in the show in "Never Trust a Snake."
* The Hageman Brothers' names for the ninja in the first beat sheet for the pilot were Ash, Wynn, Rayne, and Cole, puns on ash, wind, rain, and coal.
* When asked where the ninja get their money to buy food and games, Tommy Andreasen responded, "The[y] have a 'Kick-back-Whip-Around-And-Spin-Starter' w[h]ere people can donate."
