One interesting plot idea could be that Nick and Judy have to go undercover in a new part of Zootopia where a strange new crime wave is hitting. They have to pose as a couple, which makes their relationship more complex as they start to have real feelings for each other during the mission. Another idea is that they have to solve a mystery related to an ancient Zootopian artifact that has the power to change the city's social structure. And a third idea could be that they face a threat from a group trying to divide the predator and prey communities again, and they have to work together to stop it and strengthen the unity in Zootopia.
The plot could be that Nick Wilde gets cursed by a strange magic that makes him allergic to everything except lemons. So, he has to find a way to break the curse.

Some might try to steal his precious lemons thinking they are valuable items.
One interesting Young Nick Wilde fanfiction could be about his adventures in school, like how he deals with bullies and makes new friends. It might show his early days of developing his wily charm.
A great Nick Wilde fanfic might be one where he teams up with other minor characters from Zootopia. They could go on an epic quest to save the city from a new threat.

In the story, Nick Wilde's sexual orientation isn't explicitly stated as gay. His character is developed around his street - smart nature, his ability to navigate the complex world of Zootopia, and his growing bond with Judy. There are no story elements that point towards him being gay.
One idea could be that Judy and Nick are partners in a detective agency in a big city. They have to solve a mystery involving a series of art thefts. Their different backgrounds, Judy's from a rural area and Nick's city - bred, add to the dynamic as they interview suspects and follow leads.
Another plot could be that they discover a secret society within Zootopia that is trying to create a divide between predator and prey again.

Another plot could revolve around Nick's relationships. For example, a deep exploration of his friendship with a particular character. How they met, what challenges they faced together, and how their bond grew over time. This could add a lot of emotional depth to the fanfic.
