The Anti-Fairies, as their name suggests, are the opposites of fairies. The anti-fairies are responsible for all the bad luck on earth and, according to Cosmo, Friday the 13th is "their Christmas". Each fairy has an anti-fairy counterpart, who is their exact opposite in both personality and morality. Examples of anti-fairies are Anti-Cosmo, a cynical, evil, but smart English anti fairy who is hinted to be the leader of the Anti-Fairies, and Anti-Wanda, portrayed as a dumb, hillbilly fairy who eats with her feet. The Anti-Fairies reside in Anti-Fairy World, an enclosed environment within Fairy World, first shown as a chamber with a gate guarded by Jorgen.
