"And that complete cow Pansy Parkinson ... How she got to be a prefect when she's thicker than a concussed troll ..."
-- Hermione Granger, delighted when Pansy was hit by an antler jinx (OP10)
The antler jinx, as the name suggests, causes the victim to sprout antlers.
References from the canon
- Pansy Parkinson was hit with this spell as a member of the Inquisitorial Squad and had to miss some classes (OP30).
- Pansy Parkinson was leader of a gang of Slytherin girl bullies who constantly taunted Hermione, and laughed when Draco Malfoy accidentally made her teeth grow larger (GF18). Hermione felt "delight" when Pansy was targeted for being part of the Inquisitorial Squad and had sprouted antlers. The antler jinx might be drawing a parallel to James Potter, leader of his own gang of Marauders and known as "Prongs" because he was a stag Animagus.
