The Fairy Hunters, Ogron, Gantlos, Duman, and Anagan, are the four main villains of the fourth season. At some point, they had developed a way to resist fairy magic, which allowed them to captured the fairies of Earth, and steal all of the magic from the planet. Throughout the first half of the season, they battle the Winx, and almost every time the fairies barely make it out alive. However, as time went on the Winx became more accustomed to fighting them, and eventually were able to give them a real fight. They are defeated in the middle of the season by Bloom, with help from Roxy, who used her Believix powers to convince all of the humans in the area to believe that fairies exist. This rendered the Wizards' abilities useless, and made them vulnerable to Bloom's attack.
In the beginning of the second half of the season, it is revealed that they are still alive, but their powers are weaker than before and they must hide in the sewers. Later on in the season, the Fairy Hunters claim to be good when Duman falls ill. Duman is taken care of by Sibylla, the Fairy of Justice afterwards, though his power goes out of control and he has to be killed.
While all four Hunters seem to share certain powers, like opening a Dark Gate to capture fairies and cast dark enchantments, they also have individual powers. Ogron can absorb and deflect magic, Duman is a shape-shifter, Anagan possesses super speed and Gantlos can create shock waves.
