Godzilla: The Cowardly Cat
Life for a cat is complicated. It gets even more complicated when one's owner is Daria. It gets even more complicated than that when a zombified Tommy Sherman is thrown into the mix!
"Godzilla the Cowardly Cat" is a fic by Two-Eyed Charlie that deals with all of the above (and more)! It was nominated for Favorite Pre-Canon or Post-Canon, Favorite Science Fiction/Fantasy, and Favorite Weird Idea in the 2021 Daria Fanworks Awards.
(it's technically also a crossover with Courage the Cowardly Dog, if ya really really squint at it; at it also takes place in the same universe as The More Things Change, for no particularly good reason.)
