There is a story about a killer moth on a remote island. The island is full of unique and strange creatures, and the killer moth is at the top of the food chain there.

I really like 'Croc's Choice'. It's a short but impactful fanfic. In it, Killer Croc has to choose between following his old criminal ways or helping Batman to stop a new threat to Gotham.

One great fanfic could be 'The Redemption of Killer Croc'. In this, Killer Croc is shown as more than just a brute. Batman tries to understand his past traumas that led him to become the way he is.

Batman, instead of just fighting him, offers a chance at redemption, which creates a very interesting dynamic between the two characters.
One idea could be a story where Batman has to team up with Killer Frost to stop a common enemy that is freezing Gotham City. They start off distrusting each other but as they face challenges together, they learn to work as a team.
