Nya

''"No matter what happens next, always remember that you are the best you." ''- Nya

Nya is the younger sister of Kai and the alter-ego of the powerful Samurai X. Sensei Wu was at one point considering on training her as a full Ninja, until she became the Samurai. Nya has a crush on Jay.

Way of the Ninja
Kai and Nya working in their blacksmith shop that their Father used to own call Four Weapons. Sensei Wu comes to there shop and soon Kai drives him off. Moments later, a dark cloud appears over the small village. On the top of a hill a large vehicle called the Skull Truck appears along with many other skeleton vehicles. Kai goes to fight them and tells Nya to stay in the shop. She soon disobeys Kai and goes to fight with him. Kai starts to fight with Samukai, before a water tower was about to fall of him he is saved by Sensei Wu. Samukai tells the skeletons to take Nya and they drive away with her.

King of Shadows
Sleeping in the Forest, Kai wake up to see Nya standing nearby and calling his name. She runs away to the Fire Temple with Kai running after her. When he gets in the Temple, he finds the Sword of Fire, the last Golden Weapon needed. While he is going up to Nya, she turns into the shadow of Lord Garmadon. Then the real Nya comes out on a chain going into the lava. To save her, Kai grabs the sword. Kai starts fighting the shadows of Lord Garmadon, but is quickly defeated until Sensei comes to his rescue. Garmadon awaking the Fire Dragon, Sensei thinks of only one way to stop Lord Garmadon, by going into the Underworld to fight him, leaving Kai and Nya stuck in the Fire Temple.

Weapons of Destiny
Cole, Jay, and Zane go to the Fire Temple to look for Kai and Sensei, but Zane's sixth sense tells them they are not there. But after Zane informs them of the news, the Fire Temple slips in half, revealing Kai and Nya on top of the Fire Dragon. After explaining to the dragon that they are trying to protect the Golden Weapons, they became friends. Kai states that dragons can cross into the Underworld. Back at the Blacksmith shop, Nya finds that all the ninja are safe. At the end, Kai says, "But Lord Garmadon will return".

Secrets of the Blacksmith
Jay is flying Nya back to the Four Weapons Blacksmith Shop on the Wisp so she can pack up to move in with the ninja. Inside the Blacksmith 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 then asks what the sound was, and she replies that it was "...just some Samurai helmets and stuff." Jay, Wisp, and Nya then fly back to the monastary, and Wyplash tells his henchmen that this remains between the four of them.

Rise of the Snakes
While the ninja were playing their game and Sensei Wu was telling them to train, Nya came in and warned the ninja that Lord Garmadon was spotted in Jamonacai Village. Later, after the ninja dealt with Lloyd, Nya was in Jamonicai Village when Lloyd came back with the Hypnobrai. When the ninja heard she was in danger, the ninja came. When they found her, she told them to not look the Hypnobai in the eyes when they rattle their tails. She also told them to get the staff to use the anti-venom to cure the villagers. Before they fought the snakes, Jay offered Nya to be their honorary member.

Can of Worms
After Pythor stole the map of the Serpentine tombs from Lloyd, Nya figured out the locations of the Constrictai and Venomari tombs. Later, when the ninja were trapped, the mysterious Samurai X (Which is Nya, but was not revealed in this episode.) scared off the Serpentine, and saved the ninja. When the ninja were around the samurai and were talking to him/her, he/she sprayed sleeping gas on them. Then, after he/she flew off, The Destiny's Bounty came and picked them up.

The Snake King
After the ninja got 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" (Nya.) has taken care of the snakes, wrapping them up in a rope. Nya reports that "he just flew in, took care of business then flew out...". The ninja are under the belief that whoever catches the Samurai will be the Green Ninja for sure. The montage appears how they try in different ways to capture the Samurai, however, no avail. The ninja, back at the Destiny's Bounty, are complaining about their failed attempts to try and capture the Samurai. Meanwhile, the ninja track down Lloyd to The Lost City of Oraborus. However, they have been captured by Pythor. Then, Pythor announces another Slither Pit, one to find out: "Who is stronger? Ninja? Or Samurai?" After Pyther was making the platform vertical and revealing spikes, Samurai X helped the ninja escape. Meanwhile, after the Samurai's exosuit malfunctioned, they landed in the desert. Cole, Jay, and Zane landed together in the desert, but Kai landed nearby the Samurai, and he found out it was Nya, and she told him not to tell the others.

Personality
Although she is not a ninja, she is very well capable of defending herself. She doesn't like the fact that it's always a boy's club, so she resolved to become a hero her own way, which she did by becoming Samurai X. Sometimes she gets annoyed by Kai's protectiveness, but they love each other. She gets along well with Kai as with the other ninja. Many episodes reveal she is highly intellegent, because she was able to create Samurai armor and technology, and she was able to pinpoint the location of Serpentine tombs. It appears, that Nya is unaware of Jay's crush on her, although it seems she has figured out by Once Bitten, Twice Shy and it is confirmed she returns these feelings when she kisses him.
