Behind the scenes
- In Harry Potter and the Half-Blood Prince, Severus Snape describes the Dark Arts as though they were a creature similar to the classical depiction of a hydra: one that regrows two heads for every one that is cut off.
- It's unknown whether or not hydras actually exist in the Harry Potter Series as they aren't mentioned in Fantastic Beasts and Where to Find Them. It's possible that they are mythical, however as Cockatrices are also omitted, it is certainly possible that hydras do exist.
