Zootopia AU. Judy Hopps dreamed of being a police officer for the ZPD, but little did she expect to find the city in ruins, with the bodies of the dead roaming the streets, looking for flesh to dine on. She joins Nick Wilde, a veteran in the zombie war and becomes a member of his faction in hopes of taking the city back for good. Rated T for horror violence and blood. R&R please?

It's then Judy remembers why Nick will always be her partner- because of times like these. First Zootopia fanfiction; rated for violence.
