Sora

Frack is Arin's "best" friend since they've known each other since childhood and both shared a love for ninjas. He is a Serpentine, a snake-like being who initially had a lot of trouble integrating into Ninjago before the Fusion, due to the history of Ninjago, which dates back to time immemorial. Integration became much easier for them after the Fusion.

After the fusion, he gained the elemental power of earthquakes and was initially trained by Lord Raz until he realized he was evil and joined the Ninjas, being trained by

Wildfire was raised by a dragon in the wilds, awakening her elemental power of heat. After the fusion, she was imprisoned along with her dragon familiar in Empire until she was freed by Lloyd, Arin, and Sora when they infiltrated Empire to gather information, as Viatrix was going to build a weapon that caused fusions and threatened to create a second fusion of the fused lands.

She is trained by Kai, elemental master of fire, and although she doesn't like to follow orders, her personality is similar to Kai's and they get along very well.

His best friends are Arin and Sora, as they are the only ones his age, and he often spends time with them, although he doesn't find them as fun as Kai.

Lloyd Garmadon, son of the late Lord Garmadon, nephew of Master Wu and grandson of the first Spinshitsu master, elemental master of life, half dragon, half oni and half human

He is the master and leader of the ninja team, treating them more like a family, creating that dynamic among them all. With the new awakening of his powers, he can now take a dragon form in combat.

She likes tea, relaxing from time to time, keeping things in order, meditating, she gets a little stressed with the tasks of taking care of the monastery but not too much thanks to the help of Mr. Frogiqui who helps clean the monastery, she is a little annoyed that Kai and Wildfire burn her plants when they play with their elemental powers, she cares a lot about the well-being of her friends and about the training of Sora and Arin, she does not usually sleep much since she spends her time investigating the scrolls of the now deceased Master Wu, training or on a mission.

Arin was a small but mighty ninja boy from Ninjago who lived a normal life with his parents in Ninjago City until one morning a massive earthquake struck Ninjago, opening interdimensional rifts in the sky that began to absorb everything, even him. But thanks to the ninjas who were rescuing everyone they could aboard their ship, the Ship of Destiny, he was saved. On that tragic day, his parents, along with the other ninjas, disappeared through those interdimensional rifts, which caused a collision between the 16 realms, giving rise to the Fusion Lands, where everything was scattered everywhere and no map was useful—a place where everyone was lost. After the fusion, Arin arrived at the Crossroads, a city formed where all the roads intersected (hence the name). There, to survive, now alone, Arin began selling blackberry cakes and other ingredients from other kingdoms just to make ends meet. It was in this place that he met Zora, his new friend, with whom he experienced countless adventures, despite their falling out at the Fountain Tournament. Zora had tricked him in the fight against Vitrix, and he left with Lord Raz, who taught him to master Spinshitsu. This angered Arin, though he didn't like it in the end, as following Raz almost led to him losing Zora in his search for his parents. He found them without Raz's help, who had only deceived him with lies that they were dead, but thanks to Lloyd and the ninjas, they were found safe and sound.

Ana or Zora was a little girl from a place called Empire, a place of scientific advancements and complete order where everyone was a step further and children were taught advanced sciences to become scientists who would help in the future development of Empire. Empire was a city entirely powered by dragon energy, dragons hunted under the pretext that they were completely wild and dangerous animals. But one day, Ana won an invention contest where she developed solid light, earning the opportunity to become an apprentice to Empire's leading scientist. That day, Ana went with her through the laboratories where she saw a caged dragon trying to escape the force field that contained it, but every time it was released, it seemed to suffer. This dragon was known as Zora, meaning "abandoned" in the Empire language. Ana refused, leaving the laboratories not wanting to harm the dragons after seeing what was being done to them. But when she returned home, her parents didn't believe her, and seeing that she didn't want to help Empire with her science, they kicked her out of the house. Before that, she escaped, managing to break free from Empire's fortified walls and adopting the name Zora. Zora reached the crossroads where, as a member of Ninjago, foreign currency wasn't accepted. It was there that she met Arin, who would become a great help and family to her. Through him, she met Raiyu, the small dragon they rescued from the Empire Dragon Hunters team. They also met Lloyd, the elemental master of life and leader of the ninja team, who took them in as students, training them to become ninjas. They learned to control their elemental powers and master the art of Spinshitsu. They experienced adventures such as defeating Viatrix, liberating Empire, facing dragons and deities, and making new allies and enemies along the way, alongside other ninjas.
