Nya

''"No matter what happens next, always remember that you are the best you." ''- Nya to Jay, before he unlocks his True Potential

Nya is the younger sister of Kai, and Samurai X is her alter-ego. At one point, Sensei Wu was considering training her to be a full-fledged ninja, although this changed when she assumed the role of Samurai instead. Nya is currently dating Jay.

Way of the Ninja
While Kai and Nya are working at Four Weapons Blacksmith, Sensei Wu walks in and browses the shop, commenting that none of the items are suited for a ninja. At first Kai is hostile and tells him to leave if he's just going to loiter, but with Nya's encouragement he attempts to make a sale, only to find that the man is already gone. Moments later, a dark cloud appears over their small village. On top of a nearby hill, the Skull Truck appears along with many other skeleton vehicles. Kai prepares to fight them with some of the armor and weapons from his shop, telling Nya to wait inside. Not happy with the idea, she quickly joins Kai in the fight despite his protests. Kai attempts to face off with Samukai, but the Skulkin General disarms him with ease, forcing Sensei Wu to come in and use his Spinjitzu to distract him. Samukai throws his bone daggers at the water tower close by, sending it falling towards Kai. Before it can land, Sensei Wu pulls him out of harm's way. Samukai then commands Kruncha to take Nya, and they fall back with her in tow.

King of Shadows
Sleeping in the Forest of Tranquility, Kai wakes up to see Nya standing nearby and calling his name. She then runs off, luring him out to the Fire Temple. When he reaches the Temple, the Nya he sees reveals herself to be a shadow of Lord Garmadon. After some taunting, Lord Garmadon reveals the real Nya suspended by a chain over the lava, and tells Kai the only way to save her is to cut the chains with the Sword of Fire. Although reluctant to be playing into Lord Garmadon's hands, Kai is quick to pull the sword out of its pedestal and save Nya. Kai begins fighting several shadow versions of himself, but realizes his blows can't make contact. Sensei Wu arrives and defeats all the shadows using his own. Garmadon awakens the Fire Dragon, and Sensei Wu, thinking the only way to stop his brother is to go to the Underworld with the Sword of Fire, departs, leaving Kai and Nya to fend for themselves.

Weapons of Destiny
Cole, Jay, and Zane go to the Fire Temple to look for Kai and Sensei Wu, but Zane's sixth sense tells them they are not there. Moments after Zane informs them of the news, they hear Kai's voice, and the Temple splits in two to reveal Kai and Nya riding the Fire Dragon. After explaining to the Dragon that they were trying to protect the Golden Weapons, the Dragon seemed to agree to help them out. Nya mentions that their father used to tell them stories about the Dragons and how they ferried between their world and the Underworld. Kai and Nya agree to part ways, and Nya tells the Ninja that she'll be waiting back at the shop for their safe return. When the Ninja return to the shop, Nya is there to greet them. She hugs Kai and Jay, relieved that they are safe.

Secrets of the Blacksmith
Jay is flying Nya back to the Four Weapons Blacksmith shop on the Lightning Dragon so she can pack up and move in with the Ninja. Inside the shop, she starts packing when Wyplash, along with three of his minions, sneak up on her. After briefly distracting the group, she knocks Wyplash and Krazi to the ground before springing a trap on Chopov and kicking Bonezai. She continues to fight the Skulkin as they start to overtake her. She manages to take the upper hand by cleverly using a gong, but the noise catches Jay's attention and he comes charging in, only to find Nya alright. He questions what the commotion was about, but she explains it was just some of the items around the shop. Jay and Nya then fly back to the Monastery, and Wyplash tells his henchmen that this remains between the four of them.

Rise of the Snakes
While the Ninja are warned by Sensei Wu not to let their laziness get the best of them, Nya rushes in and informs them that Lord Garmadon has been spotted in Jamanakai Village. After the Ninja had dealt with Lloyd Garmadon instead, Nya decides to visit Jamanakai Village and sees Lloyd had already returned with the Hypnobrai. When the Ninja hear of the Serpentine threat from Sensei Wu, Kai realizes that Nya is currently there, and the four of them head out on their Dragons. After witnessing the Serpentine and the villagers they had hypnotized, they meet up with Nya. She tells them not to look the Hypnobrai in the eyes when they rattle their tails, and also mentions that the General of the tribe is holding the Hypnobrai Staff, which contains the anti-venom to cure the villagers. Jay then offers for her to be an honorary member of their team, much to her annoyance. Cole manages to take the Hypnobrai Staff from Slithraa, but just as Skales hypnotizes him, Nya comes in and kicks Skales in the face, causing him to retreat. She then tells Cole to use the staff on the fountain in town, so the anti-venom can be distributed through the water supply and restore the villagers back to their normal selves.

Can of Worms
After Pythor steals The Map of Dens from Lloyd, Nya figures out the locations of the Constrictai and Venomari tombs. Later, when the Ninja are trapped in the Toxic Bogs, Samurai X scares off the Serpentine and saves the Ninja. When the Ninja approach the Samurai to thank her, she sprays them with a sleeping gas. She then flies off, and The Destiny's Bounty arrives.

The Snake King
After the Ninja get their new ZX suits, Nya reports that Serpentine are terrorizing the amusment park. The Ninja are more than ready to reply to the call. Upon arriving, however, the Ninja find that Samurai X has taken care of the snakes, tying them up in rope. The Ninja are under the belief that whoever catches the Samurai will be the Green Ninja, and so place a bet. A montage shows how they try in different ways to capture the Samurai, but to no avail. Back at the Destiny's Bounty, the Ninja complain about their failed attempts to try and capture the Samurai. After realizing Lloyd isn't with them, the Ninja track him down to The Lost City of Ouroboros. However, upon arriving they realize it's a trap when they are captured by Pythor. Pythor announces another Slither Pit for the entertainment of the Serpentine, to find out whether the Ninja or Samurai is stronger than the other. Although seeming to fight, Samurai X reveals he was just putting on a show until an opportunity presented itself, and helps the Ninja escape. After the Samurai's exo-suit malfunctioned, they landed in the desert. Cole, Zane, and Jay landed together in the desert, but Kai landed nearby the Samurai, when he discovers that Nya is Samurai X. After a discussion, Kai promises not to tell the others about her secret.

Once Bitten, Twice Shy
Jay asks Nya out on a date, to which she agrees. However, Jay is informed of Serpentine activity at the Mega Monster Amusement Park, forcing him to cancel his date with her. As an alternative, they both decide to hold their date at the amusement park instead, although their time together is ultimately ruined by the Serpentine.

Double Trouble
While the Ninja are helping Lloyd train at the dojo, Nya walks into the room and invites Jay to come by the auto body shop, mentioning how he can help her fix the Ultra Sonic Raider in her off time. Later on, she is seen working on the Ultra Sonic Raider when Jay's Doppelganger shows up. He kisses her as a distraction while he takes the keys to the vehicle and drives off, Nya not realizing it wasn't the real Jay.

Appearance
Nya has short black hair fashioned in a bob cut, wears red lipstick, has cheek dimples, and typically wears red clothing.

Personality
Although she is not a ninja, she is very capable of defending herself. She doesn't like the fact that so much focus is put on the Ninja, so she resolved to become a hero in her own way, which she did by becoming Samurai X. Sometimes she gets annoyed by Kai's protectiveness, but their bond as siblings is strong. Many episodes reveal she is highly intellegent, as she was able to create the Samurai armor and technology, and she was able to pinpoint the location of Serpentine tombs. At first it seemed that Nya was unaware of Jay's crush on her, although by Once Bitten, Twice Shy it is revealed she returns his feelings.

Weapons
Nya has dual daggers and a long staff, and as Samurai X, she has many different gadgets as well as her Exo-suit.
