Well, this is the first fic I've ever written for Zootopia. This will be a crossover between Zootopia, Aggretsuko, and Sonic The Hedgehog (based partially on Sonic Underground and Sonic X). I published it as a Zootopia fic, since this website does not have the option to place crossover between three series in categories. And I also put it as a Zootopia fic, because I already have other published Sonic The Hedgehog and Aggretsuko fics. This fic contains fan characters that belong to me and that are children of canonical characters, who during the course of the stories will see what their personalities are like. Without more to say, here the story begins.

Main Couples: Nick x Judy x Jack ( Wildehopps / Savagehopps / Wildehoppsavage ), Haida x Retsuko ( Haidsuko ), Ookami x Fenneko ( Ookanneko ), Sonic x Amy ( Sonamy ), Tails x Cosmo ( Tailsmo ), Knuckles x Tikal ( Knuxikal ).

Other Couples: Stu x Bonnie, Bogo x Clawhauser, Komiya x Tsunoda, Anai x Hakumi, Shadow x Rouge ( Shadouge ).

It was a normal day in the city of Japan, in one of the airports of the city a plane from the city of Zootopia just arrived. In it, people who have just come to the country came either for vacations or for other reasons.

Among the people getting off the plane was a red fox with green eyes wearing a green button-down shirt, brown pants, and a blue tie; a gray rabbit with purple eyes wearing a red and white and gray plaid shirt; another gray rabbit with blue eyes that had black stripes on its face that joined at the back of its head that wear wearing a white button-down shirt, black pants, black tie and a black jacket; and lastly a brown fennec fox with light brown eyes wearing a black shirt with a red stripe and olive green pants.

These were nothing more and nothing less than two of the Zootopia police officers Nick Wilde and Judy Hopps, known as the first fox and the first rabbit in the Zootopia police forces, Jack Savage, the best known secret agent of his agency, and Finnick, an old friend of Nick's who helped out on many undercover missions.

But the four of them weren't coming. Behind them came 2 children: One was a gray and light brown vixen with green eyes, wearing a red shirt, a yellow skirt, and a blue bow on her head. The other was a gray rabbit that had black stripes on his face that joined at the back of his head, he wore a light blue shirt and brown pants.

These two children are named Nicole Wilde and Jerry Savage, they are half siblings and twins at the same time. Nicole is the daughter of Nick and Judy, while Jerry is the son of Jack and Judy. They are both 4 years old and each was standing on either side of their mother.

Some time ago Nick and Jack had fallen in love with Judy and they did everything possible to make Judy fall in love with one of them, without either of them knowing that the other was in love with her until the day they both confessed. After several unforeseen and very long counting situations one night, Nick, Judy, and Jack ended up having a threesome which led to Judy getting pregnant. After Nick and Jack realized this, they decided to help Judy, since in the end they didn't know which of the two that the unborn child could be and they felt responsible. When Judy gave birth, they realized to their surprise that they were twins and that the girl was a vixen that looked like Nick and the boy was a rabbit that looked like Jack. From that moment on the five began to be an unusual family, but over time they got used to it, although despite being a happy family there was never an official marriage between Nick, Judy, and Jack, but they lived in concubinage. They were even quite close that Nicole and Jerry referred to both Nick and Jack as their dads without any distinction and even Nick and Jack treated both children as their children without distinction from one to the other. The only thing they lacked was a stable home, as the whole family rotated between the small apartments of Nick, Judy, and Jack to live until they could buy a house big enough for all of them, fortunately they already lacked little money to get it.

Finnick on his side when he heard the news of the birth of the children and upon meeting them, they became very fond of him and began to refer to him as their honorary uncle, even letting out a side of him that even Nick didn't know and surprised him when he passed time with the kids, it was like someone other than the grumpy one he knew. Because of that, Finnick had become so close to the family that when Nick, Judy, and Jack went out to work, he stayed behind to babysit.

Now, the reason they were in Japan, was because after several years of service in the agency Jack was given the opportunity to take a vacation paid by the agency to anywhere in the world, and he could bring companions, it was which is why Nick, Judy, Finnick, Nicole, and Jerry came with him. And the reason they came to that country is because once Jack was there during a mission and he loved the country that he wanted to visit again and he was sure that his companions would love this country.

"Well, now that we are here, where is the hotel we will be staying?" Nick asked.

"It's not far, it's closer to a company called Carrier Man Trading Co., Ltd. It's quite comfortable and cozy," replied Jack.

"If it's more comfortable than my van, it will have my approval," Finnick said.

At that moment, Nicole and Jerry were drinking some water in a fountain that was a few steps from where Judy was standing, when they finished and were about to return to their mother when they suddenly found two small objects right behind the fountain. They were two brilliant emeralds at the size of their paws. One was red and the other was blue. Nicole took the red one and Jerry took the blue one. They were so beautiful that they decided to keep them. They looked at the jewels, realizing that no one was looking for them so they put them in their pockets. Nick, Judy, Jack, and Finnick didn't realize what the children had found at that time.

"Well, we'd better take a taxi to the hotel," Judy suggested, taking each of the children with her paws.

When everyone finally left the airport with their bags in paws, Jack hailed a taxi. Most of them were surprised that the people in this country were driving on the opposite side of the road, from what they used in Zootopia. After putting the suitcases in the trunk, they all got in. Finnick sat down next to the driver. While Nick, Judy, and Jack sit in the backseat, Nicole sits on Nick's lap and Jerry on Jack's.

After they were ready, the taxi left the airport in the direction to the hotel.

In another part of the same city, children were found playing in a park while their parents watched them. In a specific place in the park there was a grayish-brown and gray hyena, wearing a black and red striped shirt, black pants, a black leather jack, and black boots; an orange, white, and brown red-panda wearing a peach sweater, a white and brown plaid skirt, and black shoes; a orange, white, and brow red-maned-wolf, wearing a black shirt, white jacket, blue pants, and yellow shoes, also wore a gold watch on his left wrist; a light beige fennec vixen, wearing a light blue turtleneck, gray skirt, black socks, and brown boots; a white secretary bird with some orange and yellow feathers, wearing a blue sweater, white pants, and white shoes; and finally a gray gorilla, who wore a white dress with a red scarf and white shoes.

These were workers from Carrier Man Trading Co., Ltd who were on their day off: Haida, Retsuko, Ookami, and Fenneko, who worked in the accounting area, Washimi, who was the CEO's secretary, and Gori, who is the director of marketing. Haida and Retsuko were married, so were Ookami and Fenneko. Washimi and Gori, who were longtime friends with Retsuko, ended up becoming friends with Haida, Fenneko, and Ookami in recent years.

At that moment, two children approached them: One was a brown and gray red-panda, wearing a black and red striped shirt, and blue pants. The other was a cream, white, and brown hybrid that had the eyes, head shape, arms, legs, and height of a red-wolf, while it had the muzzle, nose, tail, and ear of a fennec; she was wearing a light blue t-shirt and grayish blue pants.

These two children are named Koka and Hana. They were best friends and had a little crush on each other Koka was the son of Haida and Retsuko, while Hana was the daughter of Ookami and Fenneko. They were both 6 years old and were playing together in a sandbox building sandcastles.

A few years ago after leaving the group of OTMGirls and having returned to work in the company, Retsuko and Haida began to get closer at first as a relationship of best friends, but with the passage of time, Retsuko decided to give a chance to Haida and realized that he was more attentive and respected her decisions than what she wanted for the future. It was like this after dating together for a while, and after a night of passion, Retsuko got pregnant, finding out about that and having talked to Haida, he proposed to her and they married shortly after Koka was born. Since then they are a happy family with their son. Even Retsuko's mother and grandmother visit them very often and even the relationship with Retsuko and her mother has improved, the only thing that still stresses her are the situations she experiences at work.

On the other hand, Ookami and Fenneko were more surprising, since they have never revealed when they started dating or how it happened, but Retsuko and Haida assume that it was at some point when Retsuko returned to work. And they only discovered them when Retsuko and Haida once caught them going home together holding hands a few days after they got off work. It was because of this Ookami started hanging with Haida, Retsuko, Washimi, and Gori more often. As with Haida and Retsuko, during a night of passion between the two, Fenneko became pregnant and after revealing it to Ookami, he proposed to her and they married before Hana was born.

They had all gathered to have a day of relaxation, and they had been in the park all morning, as it was already noon, they decided to go to lunch.

"Koka, Hana. Come on, it's time to go," their parents said.

"We're coming," they both responded in unison.

Koka and Hana had found two emeralds buried in the sand that were brightly colored. Koka had a green one and Hana had a yellow one. They wondered who could have lost them in a place like that. But since they liked them, they decided to keep them, so they put them in their pockets.

Once they were reunited with the six adults, they held hands with their respective mothers.

"I heard about a restaurant that just opened recently, and it even has an area for the children to play and have fun," Washimi said as she showed them a picture of the restaurant on her cell phone.

"And it's not that expensive either, so we can all ask for something," Gori said, holding his phone with the same image.

"Well, that's fine with me. And it looks nice," Retsuko said.

"Yeah, and it's not like those punk-style places that Haida used to take me to vent when Retsuko rejected him," Fenneko said.

"Hey, you didn't need to say that," Haida said with a little blushing of embarrassment.

"Oh, come on, friend, that is in the past," Ookami said, putting his hand on Haida's shoulder.

Koka and Hana only observed the situation without understanding from the adults, they only thought about the jewels that were found, perhaps later they would show them to their parents.

After a few seconds, the whole group finally left the park and went to the restaurant for lunch.

In another part of the city, in a dark alley, there were six beings, three of them are males beings with their respective wives and their respective children between nine and fourteen years old. Each of the male beings held an emerald, one cyan, one purple, and one white. One of them had a track in his hands. And it was seeing how far the other four were.

"According to my tracker, they are not far from here," this was a yellow fox.

"I can't believe that for the second time, we ended up in another dimension because of Chaos Control," this was a red echidna.

"Well, we have to find them quickly, because if it happened like the previous time, he might be here too," the blue hedgehog said.

Well, this is the first chapter of the story, I hope you liked it. I know there was not much action in this episode, but this was an introductory chapter of characters, in the following chapters the characters of the three sagas will meet each other. I will try to update it as quickly as possible. Without more to say until the next chapter.
