Sure. Fanfiction writers have a great deal of freedom when it comes to creating stories. With Jack Savage and Black Jack in Zootopia fanfiction, they could be re - imagined in ways that are completely different from their original portrayals. For example, they could be part of a secret society in Zootopia that is trying to protect the city from a hidden threat. This could involve complex character arcs, exciting plot twists, and exploration of the Zootopia's political and economic systems as they interact with these new versions of the characters.
