Nya

Nya is the current Elemental Master and Ninja of Water, Kai's sister, and Ray and Maya's daughter. Upon meeting, Nya and Kai joined him in his quest to protect Ninjago. As her brother trained to be a ninja, Nya grew tired of being left out from the team and created the identity of Samurai X. During this time, Jay began to start a relationship with Nya. She helped fight the Serpentine and later the Stone Army, who corrupted her using Dark Matter. After the Overlord's defeat, Nya was purified but faced new problems when a love triangle formed between her, Jay, and Cole.

After Zane's apparent demise, Nya and Dareth journeyed to Chen's Island, joining the Ninja to save the restored Zane and fight Chen's army. Following the conflict, Wu trained Nya to harness her element of water. Though her training troubled her at first, she unlocked her True Potential and destroyed the Preeminent. Consequently, Nadakhan freed his crew of pirates and wreaked havoc on Ninjago. After being captured by Nadakhan, Nya was accidentally poisoned and died, but she survived due to Jay's final wish as it undid recent events. On the Day of the Departed, Nya and Kai battled and defeated Chen, who was accidentally revived by Cole.

Nya and the Ninja went on to battle the Time Twins and their army of Vermillion. After being faced with a new Samurai X, Nya and Kai discovered that their mother and father were still alive. The family reunited, and Nya and her brother helped Wu fight and defeat the Time Twins—though Wu was lost to time.

The Ninja then faced the Sons of Garmadon, a criminal syndicate led by Princess Harumi that sought to resurrect Lord Garmadon.

After Wu and the original Ninja were seemingly killed, she, Lloyd, Misako, P.I.X.A.L., Dareth, and most of the Elemental Masters were left to resist Garmadon's oppressive reign over Ninjago. When the Wu and the others returned, they reunited and defeated the Colossus while Lloyd faced and defeated his father again. Peace returned briefly until the Oni invaded and Nya along with her friends had to evacuate the city. She experienced guilt for unintentionally leaving Cole behind, but got the idea to forge the Golden Weapons to defeat the threat. At the monastery, she and her friends fought the Oni along with Wu, Garmadon, and Cole who returned to help. During the climax of the fight, Nya accepted Jay's Yin-Yang Promise before they all used the Tornado of Creation to vanquish the enemy.

Months later, Nya and her friends fight against Aspheera and her Pyro Vipers after accidentally releasing them from their tomb. After Zane is banished by Aspheera's sorcery, she and the remaining Ninja send themselves to the Never-Realm to rescue him. Nya struggles when she is unable to use her powers, due to the realm's extreme winter freezing all water, but is mentored by an elder of the village they've taken shelter in, Sorla, to learn how to control Ice, before the village is frozen by Boreal. Nya uses her new skill to briefly knock out the Ice Dragon and discovers that Zane is the Ice Emperor. After Kai uses his restored Fire elemental power to finish the dragon off, they reunite with Lloyd and Zane, whom Vex inadvertently managed to return to normal, and use Traveler's Tea to head back to their home realm.

Sometime later, Nya 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. Nya and Jay participate in a dance competition to gain points to participate in a race called the Speedway Five-Billion and win. She, Jay, and Lloyd survive the Speedway and keep moving on without Kai or Cole as they both got cubed. Lloyd is eventually cubed in a fight with Avatar Harumi, and Nya and Jay move on to the Temple of Madness. They make it through, however Sushimi, barely alive, he throws a malice at Nya, killing her. Jay moves on alone and eventually convinces Unagami to free everyone previously trapped in the game, including Nya. They embrace upon seeing each other.

After the Prime Empire events, Nya, Wu, and and the other Ninja get an invitation to visit Shintaro. When the Ninja notice that Cole and Vania are gone, they go underground but get captured by Vangelis' skeleton army. Shortly after, Nya, Lloyd, and Jay escape with Murt to encounter Murtessa, the queen of the Munce. She and Nya fight in the Munce Arena to claim Jay, and Nya wins and becomes the new queen. At the battle of the Dungeons of Shintaro, Nya makes the Geckles and Munce work together to defeat the Grief-Bringer.
