Gargamel is the main antagonist of the Smurfs show and comic books. He is a wizard and the sworn enemy of the Smurfs.
The character was originally meant to appear only once in a short story of the Smurfs. Since he was an established adversary for the Smurfs, Peyo incorporated him into later stories, and he became the main antagonist of the Smurfs.
In the 2011 motion picture The Smurfs he is portrayed as wanting the Smurfs “mystical essence” in order to power his magical wand.
