Nabby is a is a Smurf character who is solely part of Vic George's series of EMPATH: The Luckiest Smurf fanfiction stories. According to the story series, he is the brother of Greedy Smurf, who like Greedy enjoys eating food, but lacks his brother's skills at preparing food -- thus he constantly pilfers food from Greedy's kitchen, much to the village cook's chagrin. Nabby is also a bit of a kleptomaniac, stealing possessions that don't belong to him out of habit. It is this particular habit that gets the village in trouble in the story "Snaggers Keepers" when he steals a magical amulet from a gnome that helps him control the demon that lives inside of him.
- The character of Nabby is based on the original comic book version of Greedy.
