Hero Overview

I'll lead them and I'll shut you down if it's the last thing I do.
~ Kai to Morro.

Kai is the main protagonist-turned-overall deuteragonist of LEGO Ninjago: Masters of Spinjitzu. He is the Elemental Master and Ninja of Fire, and Nya's older brother. Kai and Nya continued to work as blacksmiths in their missing father's shop. With the help of a wise master, Wu, Kai learnt Spinjitzu and discovered his three other teammates, with whom he embarked on many adventures with as they battle the Serpentine and eventually The Great Devourer.

Kai and the Ninja soon fought the Stone Army in a desperate effort to prevent the final battle, which was soon made all but certain. After Lloyd defeated the Overlord and his father was purified of evil, peace resumed in Ninjago until Pythor returned, aiding The Overlord in becoming the Golden Master and commanding the Nindroid army. The Ninja fought the Overlord and his Nindroids until Zane sacrificed himself, vanquishing the Overlord but seemingly dying in the process. The Ninja team separated until Lloyd reunited them to rescue Zane on Chen's Island. There, they competed in the Tournament of Elements before allying with the other Elemental Masters to defeat Chen's army. Soon after the war's end, Lloyd was possessed by Morro, who escaped the Cursed Realm and released a legion of ghosts. The Ninja battled Morro and his forces at Stiix before the Cursed Realm was destroyed.

The Ninja found fame after saving Stiix, with Kai becoming obsessed with his popularity. Yet they found themselves facing a new problem when Nadakhan returned with the Sky Pirates. During their first encounter, Nadakhan trapped Kai in the Sword of Souls, though he was later freed by Jay. Kai witnessed Nya die after being struck by Tiger Widow venom, though Jay's final wish reversed recent events, saving her. On the Day of the Departed, Cole accidentally revived the Ninjas' old enemies, including Chen, who attacked Kai and Nya. The siblings defeated Chen before going to Yang's Temple, where they witnessed Cole become a human.

When the Time Twins returned to Ninjago, Krux tried to convince Kai that Kai's parents were traitors. Kai and Nya reunited with their parents and stopped Krux and Acronix from changing the future. They managed to track them through time and stopped them before Wu sent Kai and Nya back to the present, while Wu ended up lost in the time.

Kai and the ninja later watch over Princess Harumi after she lost her adopted parents. They later discover that she secretly is the leader of the Sons of Garmadon and wants to resurrect Lord Garmadon. Despite the ninja's efforts, Harumi successfully resurrects Garmadon, and shortly after, Kai ends up marooned in the Realm of Oni and Dragons, which is also known as the First Realm, with Cole, Jay, Zane, and the de-aged Wu. Kai and the ninja help save the various dragons from the Dragon Hunters and help the now-teenage Wu regain his confidence and memories. After Iron Baron is defeated by Firstbourne, Wu reclaims the Dragon Armor, in turn allowing them to return to Ninjago. Upon returning, along with his fellow ninja, he takes down Garmadon's Colossus while Lloyd defeats his father, restoring peace to Ninjago once again. Afterward, he along with the other ninja attend the celebration and Kai and Skylor share a moment. When the Oni finally invade, the ninja team up with Lord Garmadon, and Kai and the rest of the ninja fight to defend their home. Kai used his blacksmithing skills to reforge Golden Weapons, using the Golden Armor, and later defeats the Oni by using the Tornado of Creation with the other ninja, Wu, and Garmadon.

Months later, Kai and his friends fight against Aspheera and her Pyro Vipers after accidentally releasing them from their tomb, and Aspheera took away Kai's power, making Kai think that he can't help. After Zane is banished by Aspheera's sorcery, he and the remaining ninja send themselves to the Never-Realm to rescue him, a land ruled by the Ice Emperor. While Lloyd went to find Zane, Kai and the others protected the Ice Fishers of Great Lake, who call Kai the Fire Maker after he relights the Hearth Fire and regains a fraction of his power. After failing to prevent Boreal from freezing the village, Kai makes up for his loss by regaining his full powers in time to destroy the Ice Dragon, discovering that Zane is the Ice Emperor. With Zane having managed to return to his senses and freeing the Never-Realm from its eternal winter, the team reunite together and use Traveler's Tea to head back to Ninjago.

Sometime later, Kai and the other ninja enter the virtual world of Prime Empire, when the legendary arcade game resurfaces and hundreds of gamers are zapped into it. Due to his recklessness, Kai was the first to lose all but one of his lives, and later, he and Cole sacrifice themselves in a race, allowing the rest to win. Eventually, Jay was able to help Unagami and Milton Dyer make amends, releasing Kai and the others trapped in the game.

Kai later traveled to the Kingdom of Shintaro on top of Shintaro. When he discovers Cole was captured by the evil Skull Sorcerer, he travels underground and helps save him. Zane and Kai later get captured by the Geckles and tames a creature known as a Mino. Zane and Kai try to unite the Geckles and the Munce but end up being captured along with Jay, Nya, Lloyd, and Zane. The Skull Sorcerer sentences them to death, but they are saved by Plundar, a member of the Upply, under Cole's command. Kai helps the other ninja fight against the Re-Awakened and they eventually succeed. Kai, Wu, and the other ninja leave Shintaro, but prepare to go on another adventure.

Kai traveled to The Island of the Keepers to save Misako and Wu. There, the ninja discovered the Storm Amulet and the existence of Wojira.

When Nya lost control of her powers, he stayed behind at the monastery along with Cole while the others went to investigate. Later on, he attempted to stop Kalmaar from awakening Wojira, but ultimately failed and he assisted the other ninja in the fight that followed. He was saddened when Nya left, and attended her memorial.

He is voiced by Vincent Tong, who voiced Prince Nicholas in Barbie: Princess Charm School, Flash Sentry from My Little Pony: Equestria Girls film series, Sandbar in the My Little Pony: Friendship is Magic TV series, while his movie voice is provided by Michael Peña who portrays Luis from Marvel Cinematic Universe

Appearance

Kai has tall, thick spiky reddish-brown hair, shaped like fire. He is often seen with a focused expression on his face, with a scar visible on his right eyebrow and bandage above his left. Before Season 8, his eyebrows were black, his bangs parted to the right and instead of a scar, he had a notch on his left eyebrow. Kai wears Red Gi's All throughout the Series. Briefly that he will wear a different color. When he was a Blacksmith, Kai wore a white shirt and red pants as well as an orange apron.

Personality

Fittingly for his elemental affinity, Kai is a very hotheaded boy, prone to taking action before he thinks things through. He is capable of making careful observations when the need arises, but his emotions often override his caution. His single-mindedness made interaction with his teammates difficult at first (especially due to his worry about Nya), but he eventually learned to work with the other Ninja. He can be arrogant at times, insisting that he is better than his peers and growing depressed when he seems to be lagging behind their training.

Later, following the Ninjas' fame, Kai would end up getting something of a larger head and bigger ego, constantly flirting with girls and enjoying the merchandise styled after him. Likewise, he indulged in his fame the most out of all of the ninja.

Kai also has something of a stubborn side, believing that he is in the right until overwhelming evidence to the contrary is presented. This is especially pronounced during Lord Garmadon's stay on the Destiny's Bounty; Kai repeatedly accused the four-armed villain of treachery or plotting despite Garmadon's insistence that saving Lloyd was his primary concern at the time. On the other hand, Kai's stubborn streak lends him incredible determination that allows him to bolster the team's spirit in the face of impossible odds.

The most prevalent facet of Kai's personality is his good heart and dedication to people he cares about—if someone can earn his friendship, he will stop at nothing to protect them. Much of his stubbornness and recklessness are due to his desire to help his loved ones, either directly or by becoming strong enough to defeat anyone who might threaten them with their plans. In turn, his friends and family work to balance out Kai's more extreme traits, causing him to become a levelheaded mentor for Lloyd by the time he and his comrades begin training the Green Ninja.

Quotes

I knew when I had to make a choice, I wanted the Fangblade so badly to prove i was good enough to become the Green Ninja. But then I figured it out, All my training to become the best ninja wasn't in preparation to become the Green Ninja. It was to protect him.
~ Kai Explaining how he unlocked his true potential to the ninja.
