• Kai Smith, a city police chief who would soon become the chief of police for a small town on a very famous island. His story is not at all easy to handle, since after becoming an important policeman and capturing several criminals, the leader of a former gang of gangsters wanted revenge against Kai, so he did not think twice and did not hesitate to murder Kai's family, who were his wife Skylor and their three-year-old son named Aiden, Kai wanted revenge, but the memory of his deceased wife and son made him see that murder was not the best option, so he only looked for the responsible and managed to capture him and take him behind bars permanently.

• After what happened with Kai, the people of the city saw him as a hero, but he decided that it was better to have a new position in a place where he did not remind him so much of where his wife and son had passed away. That is why the mayor of Ninjago sent him to be the new police chief of the famous tourist island Stiix. Kai wouldn't have agreed to go if his younger sister Nya wasn't living there.

• The real reason why Kai at first Kai didn't want to go was because of his fear of water. But he ended up taking the job anyway.

After Nya and her brother were taken to an orphanage, the two brothers did their best to stay together, and they did, they both managed to live together until they managed to become independent.

• Nya felt bad to hear that Skylor and her nephew Aiden died, Skylor was her best friend since they lived in the orphanage, and Aiden was her only nephew and her adoration.

She was at least glad to know that the only family she had left would be by her side again.

• Sometimes Nya wonders how her brother hates water, since technically she loves water.

• Jay Walker, an oceanologist and reef expert of all oceans, is Nya Smith's fiancé, he may be nervous and scared, but what gives him personality is his ability to talk to people and different animals. It would be said that Jay loves his dog Wisp more than Nya, but that is not true, Jay loves Nya with all his heart, and is even encouraged to be closer to Kai to at least show his girlfriend's brother that he is if it worthy.

• His best friend is Cole, and they are seen a lot together when they work with the killer whales at the water park. He considers Cole as a brother, the bad thing is that his dog Rocky his never stops bothering him.

• Jay's hobby is collecting shells and snails, it is something that fascinates him when he works exploring reefs in the oceans, and the ones he considers most beautiful he gives to Nya or her mother.

• When he feels sorry for something, he goes to the dolphin pond and talks to them to vent, since according to him, animals are easier than dealing with people.

• Cole Broockstone, an expert in animal behavior, dedicated his entire life to studying the life of the fauna and flora of Ninjago, but in order not to leave his home he agreed to work in the water park and in maritime research on the institute, where he is in charge of caring for and training the animals of the center and the park.

• He has been friends with Jay since they were children, and they both started working at the water park since they were little, and he was very happy to learn that Jay was appointed a scientist at the research center, and thanks to that he got to know to Nya. Cole was very happy for his friend, and even thanks to Jay, he was able to meet his girlfriend, Vania, the investor's daughter and lawyer at the water park.

• Zane Julien, is an important scientist, and is the second in command of Nya, he is mainly dedicated to investigating the anomalies of the ocean, he also investigates the climatic changes around the island. He doesn't spend a lot of time training the water park animals, as he sometimes thinks the animals don't love him.

• His girlfriend Pixal is one of the best trainers in the park, she is not a scientist, but she greatly admires her ability to build underwater equipment for the research center. Zane loves his dog Shard, but let Pixal train him, Zane just taught him how to go to the bathroom and carry the newspaper.

• When he's not locked up in his office, he spends most of his time with Jay and Cole and helps them take care of the animals.

• After learning that Nya's brother would come to the island, he offered to give her all the information about the events that occurred throughout the island and its beaches. And he even gave a personal tour of the research center and the park.

• Wu Montgomery, is the head of the research center, he and his brother, Garmadon, opened the center after his father opened the water park, shortly after the site was handed over to Mayor Dareth, but he let the brothers combine its center with the water park.

• Wu is head of the research center, he is also an important scientist on the island, but lately he has had problems with the maritime hunter, Ronin Grest, as his attacks on his marine animals have caused the center to receive a bad name for not caring good for the animals. Still, he doesn't give up and was very happy to receive Kai's help.

• Wu loves his family, but sometimes everyone thinks that he cares more about the center than his family. But that's not true, he loves his family more and his nephew Lloyd more, but due to threats from Ronin and his men on his side, he hasn't had time to spend quality time with his brother, Garmadon, Misako and Lloyd. Also, he has a love interest in Koko, his assistant and his best friend at the center.

• Garmadon is an animal behavior scientist at the institute, but normally works as a guard at the center, the park may no longer be fully in the name of his family, but still, he is relieved to learn that Dareth maintains the park afloat.

• Lloyd is a 10-year-old boy who loves to be in the water, downtown and in the park. He wants to be a great maritime researcher like his father when he grows up, he loves being next to Nya, Jay, Cole and Zane, as they teach him everything about animals and the ocean, he even learned to surf thanks to Cole and navigate on Jay's side his dragon dog is one of his best friends and he won't go anywhere without him. After meeting Kai, see something in him that like and adore, sometimes even try to imitate him, although that's what amuses guys, because if you want to look like Kai, you would need to be grumpy, serious and self-centered.

• Morro Wind, one of the island policemen, became Kai's second in command after proving his worth to him, usually helping Kai with some minor island problems and completing some paperwork. He normally prefers to stay away from fishermen and the Ronin gang, as they are the toughest and dumbest men on the island.

• Ronin Grest, a hunter of sea creatures who looks like a kind of pirate in the eyes of the inhabitants of the island, he hates to be told the importance of maritime life since he only thinks about money and killing animals . He has married whales, sharks, sea lions, dolphins and caught a large number of fish in the ocean. And seeing that the center protects him and prohibits him from hunting in some places on the island annoys him, and as revenge he sometimes hunts and hurts several of his animals that have been releasing sea, to then spread rumors that the center is not so he good at taking care of his animals.

• His shark hunt caused the entire family of wild and murderous white sharks to start attacking people on the island, including other aquatic animals, and even destroyed several of the center's underwater equipment. This was because Ronin thought he had caught adult white sharks, but rather caught baby great sharks. However, Nya and the others managed to rescue one of the hatchlings and brought her to the center so they could monitor her.

• Pythor and Skales are two policemen from the island who annoy Kai a lot by telling him that he is not such a good policeman to remedy the problems of the people of the island. They do this because Pythor was going to be appointed chief of police, but since Dareth had doubts about his actions, she decided it was best to enlist the help of the famous Ninjago city cop, Kai Smith. This infuriates Pythor, as he believes that he is the best cop on the island, in addition to supporting Ronin's actions, he sometimes does things behind Kai's back, just to annoy him.

• Dareth Marron, the mayor of the city of Stiix, makes sure that the city is a great tourist place so that he can make the city grow more thanks to the profits of tourists and city people, how much with investors and Island entrepreneurs, part of being accompanied mostly by the judge, Cyrus Borg, and the sales entrepreneur, Clutch Powers. The problem with him is that he is quite proud, innocent and very disinterested in some things.

• Speaking now of sharks, you should know that sharks do not normally attack people like they do in the movies, however the wildest sharks are white sharks, but they do not attack people directly every time, unless they sit down. threatened when there are people in their territory.

• Sharks don't normally kill people, they only bite you as a warning and it depends on the bite if it kills you or not. Sometimes sharks can also eat you if they are very hungry, they even kill other sharks just with the intention of surviving. They also attack when attracted to the smell of blood from anything.

• The sharks in the story are inspired by killer sharks from various movies. However, these sharks will be the species of white sharks, but thanks to recent discoveries, it has been discovered that some sharks have reached a size of almost 5 to 20 meters long, this depends on their living conditions, feeding and reproduction. Also due to pollution, this sometimes causes some sharks to mutate in size to better suit where they live.

• The sharks in the stories will measure a maximum of 17 to 20 meters, and the intention for which they attack people is because the storm diverted their path from the deeper waters, they had no choice but to take another path and that led to the island of Stiix, where the female gave birth to her young, the parents prowled the island and discovering that there was enough food for them and their young decided to prowl the deep waters of the island, but after their nest is attacked by Ronin and His men, the parents considered this to be a threat to their new territory and began to act aggressively at anything that moves underwater. Only two hatchlings survived, but one of them was taken to the center, and it turned out to be the smallest hatchling of the litter, the second turned out to be one of the largest, after leaving the nest it joined its parents in the attacks, step most of the time eating any food in order to grow taller, and as the days went by he got stronger, but he was still young.

• They began with attacks on the marine center animals that were released, which included whales and other sharks, then began with attacks on fishing boats and ports. After finding entrances leading to the center and the water park, they began destroying various equipment to secure their entrance. After that they started hanging around the island's beaches, wanting to make sure where more people gathered when they went swimming.

• Sharks sometimes do not eat their victims and let the currents of the sea carry them to the shores of the beaches, since they want to leave very threatening warnings of their presence. They do not hesitate to devour anyone who is in the water, and since they are very strong they have sunk some fishing boats and mini-submarines in the center. Their aggressiveness is due to the fact that in their old home they have been exposed to multiple types of contamination, more than caused by humans, and knowing that someone destroyed their nest, that made them feel threatened and that they became more aggressive than normal. And after tasting human meat, nothing stopped them from tasting that meat more.
