Putting this here because I don't think it qualifies as an AU, all the Cannon Zootopia stuff apparent;y happened exactly as it did in the movie, and this takes place a while after that. After being (apparently) framed for a grisly murder, Nick is on Death Row and mere minutes away from his execution before Judy stops it because she needs help on a case, and Nick is the only one she thinks can help her, even if she still thinks he's a murderer. Also, there's a subplot about a war that Zootopia is involved in with a mysterious eastern country that may or may not have anything to do with the main plot. Only one chapter at the time of writing but it is very good.
