Ninjago (TV series)

Ninjago (previously known as Ninjago: Masters of Spinjitzu until 2019) is an animated epic-fantasy superhero television series produced by The Lego Group. It was created to coincide with the Lego Ninjago line of construction toys, which is based on the characters and events of the series. It centers on the fictional world of Ninjago, telling the story of a group of six teenage ninja and their battles against the forces of evil. The series was created by Michael Hegner and Tommy Andreasen, two Danish film producers. The storyline was written by Kevin and Dan Hageman until the ninth season; their successor as the head writer was Bragi Schut. The show features a large ensemble cast of voice actors who had recurring roles in the series. The English-language voice cast was recorded in Canada for its entire run. The music was scored by composers Michael Kramer and Jay Vincent.

The series was in continuous production for over a decade and celebrated its tenth anniversary on January 14, 2021. It began with two pilot episodes in January 2011, which were followed by two 13-episode seasons that aired from December 2011 to November 2012. Both the Lego theme and the series had an intended shelf life of three years with the second season planned as the original ending. However, the success of the series and its product line led to the show continuing production, with thirteen more seasons, a special, a feature film adaptation, and a four-episode miniseries being released. Ninjago: Masters of Spinjitzu was produced in Copenhagen, Denmark, by Wil Film ApS for its first ten seasons. The production was relocated to WildBrain Studios in Canada for the eleventh season, and the series was retitled Ninjago. The series concluded on October 1, 2022, with the second part of the fifteenth season being released on Netflix in Australia and New Zealand.

In Denmark, where the series' original production companies are located, it premiered on Cartoon Network. It aired on various Cartoon Network feeds internationally. In the United States, it aired on Cartoon Network until 2020, when premieres moved to Netflix. In Canada, the series was broadcast on Teletoon and YTV.

A sequel series titled Ninjago: Dragons Rising, set in the same continuity, debuted on June 1, 2023.

Synopsis
The show is largely set in the fictional realm of Ninjago, a place loosely inspired by East Asian myths and culture. While featuring historically designed buildings and traditional clothing, Ninjago exists in a modern setting centered around the large metropolis of Ninjago City, which features skyscrapers, current-age and futuristic vehicles, modern electronics, mechanical exo-suits (mechs), and other futuristic technology. The plot focuses on a group of six teenage ninja fighting against the forces of evil, who are also defined as "Elemental Masters", several characters who have elemental powers.

The series began with the ninja team being formed and trained by their ancient master Sensei Wu in the fictional martial art of "Spinjitzu", which is the main fighting method depicted in the show. The ninjas' base is a flying junk ship named "Destiny's Bounty", which has varied in design over the course of the series. The pilot episodes introduced the original four ninja characters named Kai, Cole, Jay and Zane and Kai's sister Nya, while the central character Lloyd Garmadon was introduced in the first season, titled Rise of the Snakes.

The series incorporates a detailed fictional lore, which is woven into the storyline using character dialogue and flashbacks. The lore mainly focuses on the history of the First Spinjitzu Master and his creation of the island of Ninjago:

Cast and characters

 * Lloyd Garmadon (voiced by Jillian Michaels in Seasons 1–7 and Sam Vincent in Seasons 8–15 ) is the Green Ninja and Elemental Master of Energy, 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 following the pilot episodes 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 (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 (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 arrow. His elemental power 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 humour, 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.
 * Cole (voiced by Kirby Morrow from the pilot episodes–Season 14 and Andrew Francis in Season 15) 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. Described as 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.
 * Nya (voiced by Kelly Metzger) is the grey/blue ninja, Elemental Master of Water and the original Samurai X. She frequently wields a sword and, more recently, a trident. In early seasons she wears red as Samurai X and later, dark red. 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 most mature decisions of 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, the daughter of Ray and Maya and the girlfriend of Jay Walker.
 * P.I.X.A.L. (Primary Interactive X-ternal Assistant Life-form) (voiced by Jennifer Hayward) is a female nindroid who makes her debut as an assistant to her creator/father Cyrus Borg in the third season. 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 thousands of years.
 * Lord/Sensei 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 of the pilot episodes and an overarching antagonist of the first two seasons. In Season 2, he is cleansed of evil and becomes a sensei to the ninja in Season 3. In Season 4, he is sacrificed to the Cursed Realm and resurrected in Season 8 as a being of pure evil. After conquering Ninjago, his reign of terror is finally brought to an end by Lloyd 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. In Season 15, he reappears to help the Ninja fight the Overlord. Because of his Oni heritage, Garmadon has lived for thousands of years.

Concept
In 2009, The Lego Group proposed to make an original intellectual property about ninja, which focused on four ninja with elemental powers. The Lego Ninjago theme concept originated in the Lego Ninja theme, which was released by The Lego Group in 1998. This theme was then replaced by Lego Knights in 2000. In 2011, Lego Ninjago was launched and included some of the concepts from the Lego Ninja theme, such as dragons and fortresses, but also combined this with a modern setting. The Ninjago: Masters of Spinjitzu television series was created by Michael Hegner and Tommy Andreasen, two Danish film producers.

During the early development of the concept, The Lego Group conducted ethnographic research with children to determine their interests. Cerim Manovi, Senior Design Manager for the theme recalled, "Ninjas crystallised themselves because we were, like: 'What's the greatest hero entry point?' We showed them superheroes, everything – but ninjas just grabbed kids right there". The Lego Group had been attempting to develop a toy line based on ninjas for several years but a product range had never been successfully developed due to the limitations of the concept. This changed once the idea was developed into a high concept fantasy theme. Researchers at The Lego Group began testing ideas for enemies and eventually skeletons were chosen as the main antagonists in the storyline, following research conducted with six-year-old boys. The skeletons were considered to be the perfect adversaries for the ninjas because they looked inherently evil and fantastical. Other initial concepts for the enemies, such as snakes and robots were rejected, but then used later in subsequent seasons of the series. The ninja characters were given different coloured suits and unique elemental powers to make them more interesting and give them individual personalities. The motivation for the ninja characters was initially presented as a fight about obtaining four golden weapons.

The first concept drawing was created by Tommy Andreasen in late 2009, which depicted five elemental ninjas with their elemental tornadoes and included the word "Spinjago". This would later become the fictional martial art of "Spinjitzu", a combination of the words "spin" and "ninjitsu". Andreasen recalled being called into a meeting on a Friday evening where he created the rough concept sketch of the characters. He then contacted an artist in Canada named Craig Sellars, who painted an internal concept image of the characters over the weekend and sent it back on the following Monday. Andreasen recalled that this was a "linchpin moment" that was the beginning of the concept and the television series. The Ninjago brand name was a combination of the words "ninja" and "go", which was split from the end of "Lego". The series title was also used as the main ninja battle cry.

Writing
Kevin and Dan Hageman were the screenwriters for the Ninjago television series from the initial development phase until the ninth season. They became involved in the project after being invited to pitch an early story concept for a Lego-based movie that would eventually be titled The Lego Movie. After making a successful pitch to The Lego Group for the film, the Hageman Brothers were asked to write the story for a 44-minute animated television special based on an original Lego property about ninjas. Initially it was intended to be a one-hour special, but the Hageman Brothers decided that they wanted to make it into a saga similar to a high-end blockbuster movie, "like Star Wars with ninjas". They took their inspiration from movies and television shows of the time, including films produced by Marvel and Steven Spielberg. Dan Hageman recalled, "We're looking at Star Wars. We're creating a land and there's magic in this land, there's weapons in this land, there's vehicles in this land...we wanted to make something not necessarily that would appeal to children, but that would appeal to us". Kevin Hageman noted that there was a lot of disposable entertainment for children at that time. He explained, "We wanted something that treats the kids intelligently, also emotionally intelligently. They understand drama. Let's give them a story that's going to continue because it's serialised...we thought of it more as one giant movie or a miniseries. I think that really added a lot of depth, a lot of heart, to Ninjago that you don't see on other shows".

The Hageman Brothers were presented with the basic concepts and characters for the show, such as the ninja, dragons and spinjitzu, but developed the characters' motivations and personalities. They decided that the characters were imperfect and were motivated by their relationships. They also decided that Kai needed to be the main character of the Pilot Episodes because the special was limited to 44 minutes, so they agreed to centre the story around one character, rather than a large ensemble cast, and to give Kai a specific motivation. For this reason, the Hageman Brothers came up with the character of Nya, the main female character in the story. Kevin Hageman explained, "We wanted this to be a show that boys and girls like, and I wanted strong, young female characters in it - so we created Nya". Tommy Andreasen explained that the character of Nya was employed as an emotional reason for Kai to get involved because, "he didn't want to be a ninja, but his sister was kidnapped by this evil Lord from the underworld".

The character of Lloyd Garmadon was conceived by Dan and Kevin Hageman. Andreasen stated, "The Hagemans came up with the idea of Lloyd, the son of Garmadon. As soon as they introduced that idea, we knew Lloyd was going to be the Green Ninja and we were going to build that mystery up over 10 episodes".

The Hageman Brothers eventually left the show after nine seasons when Bragi Schut took over as writer. Kevin Hageman asked Bragi Schut to become involved in the series due to his background of working in film. Despite not having any prior knowledge of Ninjago, Schut became familiar with the story and continued it with the same approach as the Hageman Brothers, ensuring that it included "a combination of humour, heart and adventure".

Animation and format
The first ten seasons were produced in Copenhagen, Denmark, by the animation studio Wil Film ApS. Erik Wilstrup, the CEO of Wil Film, first became aware of the project in October 2009 when The Lego Group was exploring ways to create branded entertainment using animation. Wilstrup and his team proposed a variety of animation styles before agreeing that computer-generated imagery (CGI) was the best option. Wilstrup elaborated further on the production of the series by describing Wil Film as "a spider in the middle of a wide web and a responsible driver of it all". He explained, "Specifically we have a team of designers in Berlin, while the voice recordings sit with BLT in Canada. The score is produced by Jam Hollywood in Los Angeles, the animation is done at GDC in China and all preproduction, storyboarding, blocking, post-sound, on-line and grading is done in our studio in Copenhagen."

The production was relocated to WildBrain Studios in Canada for the last five seasons. This marked the use of new animation styles, including anime-style 2D animation, as a way to experiment with the storyline and add new creativity to the show. With the release of Secrets of the Forbidden Spinjitzu, the run-time for the show was revised from 22 minutes to 11 minutes. This was a particular cause of concern with fans of the show. Tommy Andreasen commented on the 11-minute format by stating, "it was a way for the broadcasters to make it easier to programme". He has also remarked on the positive nature of the new runtime, stating, "Once you're working with 11 minutes it's not just the same idea stretched over two 11s. Now it's a new idea in every episode, and it really makes you risky and fresh - and able to tell stories very efficiently...If there's something I would like Ninjago TV show to be, it's this creative playground, where you should never know exactly what you can expect".

Character design
Following the initial concept sketch created by Tommy Andreasen in late 2009, concept artwork depicting the main ninja characters was created in 2010, with a character drawing of Lloyd and sketches to summarise the first two Ninjago seasons. In addition, sketches of Nya were first produced by Tim Ainley, depicting the character as a samurai, followed by character, model and part designs.

In the eighth season, the appearances of Lloyd and the ninja were noticeably different from their appearances in previous seasons. Sons of Garmadon implemented a new phase for the ninjas' designs, which were now based on the designs of their movie counterparts in The Lego Ninjago Movie. The design change aimed to help new fans of the movie transition to the television series. The start of the season marked updated appearances for each of the main characters, including changes to their hair and faces, and these new appearances have continued to be used throughout subsequent seasons. Although Lloyd looks almost identical to his movie design, he was given a new voice actor Sam Vincent, who took over the role from Jillian Michaels, while the other ninja retained their original voice actors. Design Manager, Michael Svane Knap explained that these changes were inspired by the movie in terms of the detail level. He commented, "We pulled in some of the character designs from the movie into the TV show afterwards. That was born of wanting to get more uniqueness to the characters. Something that added a lot of character to these ninja that we didn't have before were the hairstyles for them, so we managed to create something that was completely unique for Ninjago with how the characters looked".

Music
The title sequences for seasons 1–7, 11–13, and 15 feature The Weekend Whip, a song performed by The Fold, which is the show's official theme song. The Weekend Whip was remixed each season to reflect the theme. Seasons 8–10 and The Island–season 14 feature music by composers Michael Kramer and Jay Vincent, with Ninjago Overture as the main theme.

Jay Vincent and Michael Kramer scored the soundtrack for the series since the beginning of the show. Michael Kramer had previously created a martial arts track that Vincent and Kramer decided was perfect for the show and this music piece Ninjago Overture was chosen as the main theme for the show. Although they were initially hired to write some original music for the characters, they decided to score the entire pilot special. The music plays a significant role in the storytelling, particularly in terms of helping viewers to distinguish between the heroes and villains. Kramer explained that there were ground rules that were established from the beginning of the show, stating, "One thing that we try to stick to, not always but generally speaking, is that bad guys usually have more bowed instruments and good guys usually have more wind instruments. The idea of friction being more bowed or struck instruments". The music is also used to underpin the drama in the show. Kramer remarked on this stating, "These characters are real for us. That allows us as composers to really dive deep into that drama. And I mean, it gets really heavy - especially in Season 10 with the Oni - it got really dark, really dramatic". The soundtrack incorporates a wide variety of traditional musical instruments from around the world, which were carefully chosen to illustrate each character or land in which the season is set. Jay Vincent commented that, "because Ninjago is set in this vast universe, we get to respectfully but enjoyably explore other cultures of the world that we might not be familiar with".

The Fold became involved in the show through Jam, a music production company in Copenhagen. The producers wanted to include modern concepts within the show, so they were looking for a catchy pop song. After being initially approached by Michael Kramer, The Fold came up with The Weekend Whip, which was designed to be listened to outside the context of the show and was described as "the dance that the ninja do on the weekend when they are off". The demo was included in the pilot season and recorded in studio a year later.

In January 2021, The Lego Group released a soundtrack video on YouTube titled Ninjago: A Musical Journey, which celebrates the music of the show in four parts. The complete Ninjago: A Musical Journey (2011–2020) video was released on the Lego YouTube channel on 6 June 2021, comprising 2.5 hours of music and images.

Launch
The Lego Group launched Ninjago: Masters of Spinjitzu in January 2011 with the release of two 22-minute animated specials that aired on Cartoon Network in January and March. These pilots introduced the main characters and the Ninjago universe to its target audience. Following the success of the pilots, The Lego Group announced the release of the first season on 23 March 2011, titled Rise of the Snakes, which aired at the end of 2011 and consists of 13 episodes. The series continued to be written by Dan and Kevin Hageman. Jill Wilfert, Vice President of licensing & entertainment at The Lego Group commented, "We're thrilled to be working with Wil Film and Kevin and Dan Hageman to add yet another dimension of story and engagement to our newest original property".

Suspension and continuation
The Ninjago: Masters of Spinjitzu series and accompanying product line had originally been planned as a three-year project. The conclusion of the second season titled Legacy of the Green Ninja emphasized the end of the show in its season finale, with the character of Lloyd becoming the "Golden Ninja" and defeating the main antagonist, the Overlord, in an epic battle of light and darkness. However, due to the incredible sales performance of the Lego Ninjago product line, the series was continued. Senior Creative Director Simon Lucas recalled the company's decision to extend the series, stating, "we had six weeks to say what we would do with Ninjago. How do you bring it back? We had the final battle in the story. Immediately I connected with Kevin and Dan Hageman, and we just agreed that this world we'd created, the characters and the story had so much more to give. We actually struggled to filter ideas, because we had so many". The continuation of the series allowed the writers to open up their ideas about what the theme could be. It also pushed them to change the Ninjago series each year, which contributed to the success of the show. Kevin Hageman opined, "If we just kept doing the original theme and just had different adventures... Ninjago would not still be here today. I think it's truly here because the restrictions forced us and Lego to keep redesigning and rethinking Ninjago and it kept becoming this beautiful big universe where anything is possible".

Critical reception
Ninjago has received largely favourable reviews from critics. Reviewer Lien Murakami for Common Sense Media gave the Pilot season a three out of five star rating, describing it as "exciting and funny" and noting that "the ninja characters learn lessons of patience and teamwork from their wise sensei". However, the review also opined that the show "is essentially an extended advertisement for the Lego Ninjago toy line". Melissa Camacho for Common Sense Media gave Tournament of Elements a three-star rating and commented on the "positive messages" and "character strengths" in the series stating, "Lessons about loyalty, loss, sacrifice, and teamwork are emphasized throughout." Possession also received a three-star rating from Common Sense Media, and reviewer Melissa Camacho commented, "loyalty, teamwork and sacrifice are common themes, making this a solid choice for action lovers. The loss of a loved one also is a central theme in this series installment." Dave Trumbore for Collider commented on Skybound, giving the show a four-star rating and stating that it is "a fun romp through the mythology in the modern era that emphasizes teamwork, cooperation, and loyalty throughout, all while providing a highly entertaining and action-packed series". Skybound also received a three-star rating from Common Sense Media, which noted that the season, "contains some positive messages about friendship, patience, loyalty, and gender equality." Common Sense Media gave Hands of Time a three-star rating, with Melissa Camacho commenting that the season had good messages, fantasy violence and, "some fun moments, especially when the teens banter with one another. But central to the show is their effort to help Ninjago, a well as their master, by using their powers accordingly." Camacho also gave Hunted a three-star rating and commented, "they're a loyal team and do what they believe is right in order to ensure that good triumphs over evil. If you're a Lego Ninjago fan, Hunted won't disappoint." Barry Hertz for The Globe and Mail commented, "Ninjago is a 10-season-long commercial for one of the world's most expensive toy-lines. Yet, its crass existence is consistently and miraculously outweighed by the imagination of and creative powers behind the long-running series. Ninjago: Masters of Spinjitzu should be terrible, but it is instead one of the more enjoyably complex and mythology-heavy series out there - no matter whether you're the babysitter or the babysat."

Light and dark
One of the most dominant aspects of the Ninjago series is the theme of duality, or light and dark (with reference to the yin and yang). In the fictional realm of Ninjago, the two main elements are creation and destruction, which are the definition of good and evil, and are shown to either create life or destroy it. The main characters that have been depicted wielding this power are Master Wu, who represents creation and Lord Garmadon who represents destruction, being the direct descendants of the First Spinjitzu Master, the legendary fictional creator of Ninjago. Many villains throughout the series have been defined by darkness and destruction, most prominently the Oni, while the main character Lloyd Garmadon has been associated with light, particularly when he was shown to have achieved his "Golden Power" in the second season.

Teamwork
The importance of teamwork has also been a fundamental aspect that runs through the series. Senior Designer Christopher Stamp commented, "The characters are flawed and individually they are not complete, but as a team they complete each other. You follow the characters' development, it allows a form of natural evolution so as you go through the stories. The example I always come back to is when Cole questions if he is really important to the team, would the team still exist if he wasn't there? That led us to introduce ghosts to the world of Ninjago, what if he's a ghost? Then we realize when he actually becomes invisible, the team doesn't function the same way without him."

True potential
The series presents recurring moral lessons beneath the story that are intended to be absorbed by the viewers. In particular, the main character Master Wu has been depicted repeatedly placing emphasis on overcoming the internal obstacles that can hold a person back from achieving greatness. This theme was also illustrated by the main ninja characters conquering their personal obstacles and achieving their "true potential". Tommy Kalmar, Story and Entertainment Manager commented, "Beneath the icons of dragons and ninjas there's this compelling full narrative around kids gaining confidence, finding their inner voice, learning something new about themselves, realizing something, and suddenly they can do more."

Influence and legacy
From its launch in 2011, the Ninjago series achieved continued popularity amongst its target audience, who are mainly primary aged children and teenagers, but it also gained a dedicated fan community. The Ninjago writers ensured that children are able to relate to the main characters by making them teenage heroes, and this made them consistently popular characters. In 2017, Christopher Stamp, Senior Designer at The Lego Group, noted that Lloyd and the ninja are relatable to children due to their inherent flaws, stating, "What is the main thing that has caught kids’ attention? Why is it so relatable? I have thought about it a lot. For me personally, it has got to be the characters. None of the characters are perfect, they are all flawed and I think that is something everyone can relate to."

From 2011 to 2022, the Ninjago series included storylines that aimed to teach about the importance of friendship, inclusivity and confidence. In 2017, Lego design manager, Michael Svane Knap commented, "It’s always important to develop good characters that engage with the kids and encourage them to watch. The story that we have been telling from the beginning has been focused on family, collaboration and emotions and these are the keystone for telling a good Ninjago story". The Ninjago series was in continuous production for over a decade, resulting in many children having grown up following the series and developing into adult fans. Knap remarked, "Some have grown up with Lego Ninjago and are now expressing their gratitude and telling us how they have learned lifelong skills".

On 5 February 2019, Ernie Estrella for Syfy Wire remarked that, "Ninjago is one of Lego's long running, home-grown franchises, and is arguably its most successful one."

Tenth anniversary
On 14 January 2021, the Ninjago series celebrated its tenth anniversary. This milestone reflected the continued popularity of the show amongst its audience. Tommy Andreasen, Senior Manager and co-creator explained, "Originally, the Ninjago theme was supposed to end after season 2 in 2012. It just shows an incredible commitment from our fans that we are still going strong 10 years later". In April 2021 a three-hour documentary produced by four Ninjago fans was released on YouTube, titled Ninjago - Ten Years of Spinjitzu: A Documentary. It recounts ten years of the series and features interviews with Tommy Andreasen, the Hageman Brothers and various voice actors from the show. In June 2021, The Fold released a song titled Ten for Ninjago to celebrate the ten-year anniversary of the show.

Merchandise
The Ninjago TV series was launched to coincide with the release of its product line, Lego Ninjago in January 2011. In its first year, 17 Lego construction toy sets from the product line were released. After that, Ninjago-themed playsets were released each year to correspond with each season of the TV series.
