Another possibility could be Clawhauser and a new character. Clawhauser is such a friendly and loveable character. A new character could enter Zootopia and they start a journey together which involves the 'hundred kisses'. It could be a story about new friendships and how they use these kisses to make the city a better place.
It could also be the mayor of Zootopia and his or her assistant. The power dynamic and the relationship between them can be explored in the context of the 'hundred kisses'. Maybe the 'hundred kisses' are a way to improve their working relationship and in turn, make better decisions for the city.
I don't know for sure as I haven't read it. It could be Judy Hopps and Nick Wilde since they are very popular characters in Zootopia. But it could also be other characters that the author of the fanfiction decided to focus on.
It's probable that the main characters would be those that represent different aspects of Zootopia society. So, along with Judy and Nick, there could be a business - minded character like Mr. Big who gets involved in this 100 kisses concept. He could be using his influence to promote the idea of love and unity through these kisses. And of course, there might be some minor characters from the movie that are given more importance in this fanfiction and are part of the main cast because of their connection to the kisses, like the otter who had that incident in the movie and now is part of a new love - centered story.
Since it's a Zootopia fanfiction, it's likely that the 'one hundred kisses' are part of a plot device to drive the story forward. It could be that the main characters are in a situation where they gradually reach this number of kisses over the course of their relationship. It might also be a comical take on the idea, like they accidentally keep ending up in situations where they kiss and then they start counting. Or it could be a more serious exploration of love in a world full of different animals, where these kisses are a way to show the connection between two characters who might be from different species or have different social standings.
One interesting plot could be two characters who start off as rivals in Zootopia but through a series of events involving 'hundred kisses' (maybe symbolic kisses like acts of kindness), they end up falling in love. For example, a fox and a rabbit might initially be at odds due to the natural predator - prey relationship in their society. But as they exchange these symbolic 'kisses' of mutual respect, understanding, and help, they break down the barriers between them.
A scientist could be a main character. In this human Zootopia, they are researching a new form of energy that could change the world. However, they face opposition from traditional energy companies who will stop at nothing to keep their monopoly. The scientist has to fight against all odds, with the help of some unlikely allies, to make their discovery known and beneficial to all.
I'm not sure specifically as there could be many different plots in a fanfiction with that title. It might involve various characters from Zootopia sharing 100 kisses in different scenarios, perhaps as a way to show love and friendship among the diverse animals in the city.
I don't know for sure as I haven't read this '20 kisses fanfiction'. But it could be the typical characters that are popular in the original work that the fanfiction is based on. It might be the two main protagonists of a love story from a book, movie or TV show.
Judy Hopps and Nick Wilde would surely be main characters. They are the protagonists in Zootopia and their dynamic personalities would make for great interactions in the human world. They could be the ones to bridge the gap between the two worlds, with Judy's determination and Nick's street - smartness.
It's possible that new characters are introduced in this fanfiction. But the mainstay from the original movie, such as the police officers in the Zootopia Police Department that Judy works with, might also have important meetings within the context of the story. Their interactions could be used to show the different aspects of life in Zootopia, from the law enforcement side to the civilian side.
There could be a war - torn soldier as one main character, who has seen a lot of bloodshed and whose kisses might be 'bloody' in a metaphorical sense. And a healer or a gardener with a'strawberry smile' who tries to bring some peace and light into the soldier's life.
