======Water Demons======
=====Creature Information=====
  * **Type:** [[Magical Creature]] (Classification Category)
  * **Habitat:** Aquatic environments such as [[Black Lake|lakes]], ponds, and rivers.
  * **Known Examples:** [[Grindylow]], [[Kappa]]

=====General Description=====
"Water Demon" is a classification for a type of malevolent [[magical creature]] that dwells in water. There is no single appearance for a Water Demon; rather, the term encompasses various species with different forms that share a common habitat and aggressive temperament.
Common characteristics include a dangerous nature towards humans and an aquatic or semi-aquatic existence. Known examples display varied appearances:
  * **[[Grindylow]]s:** Described as sickly green creatures with sharp little horns, long, spindly fingers used for gripping, and tentacles for propulsion.
  * **[[Kappa]]s:** Japanese water demons that resemble monkeys covered in fish scales, with a hollow on the top of their head in which they carry water (`//Fantastic Beasts and Where to Find Them//`).
=====Abilities and Dangers=====
Water Demons are generally considered dangerous to both [[Wizard|wizards]] and [[Muggle]]s. Their methods of attack are suited to their aquatic environment, often involving dragging victims underwater.
  * **[[Grindylow]]s:** Possess a surprisingly strong grip and will attempt to seize and drown their victims. They are vulnerable to the [[Revulsion Jinx]], which forces them to release their hold, and they have brittle fingers that can be broken to escape their grasp.
  * **[[Kappa]]s:** Are particularly dangerous, known to feed on human blood and strangle people who enter their ponds or rivers. The strength of a [[Kappa]] is intrinsically linked to the water held in the hollow on its head. If one can trick a [[Kappa]] into bowing, the water will spill out, rendering it powerless (`//Fantastic Beasts and Where to Find Them//`).
=====Known Mentions and Encounters=====
The term is first used by Professor [[Remus Lupin]] during a [[Defence Against the Dark Arts]] lesson in the 1993-1994 school year, where he identifies [[Grindylow]]s as Water Demons and uses one for the third-year final exam.
During the [[Second Task]] of the [[Triwizard Tournament]], [[Harry Potter]] is attacked by a swarm of [[Grindylow]]s in the [[Black Lake]]. He uses the [[Revulsion Jinx]] to fend them off. [[Fleur Delacour]] is also attacked by them and forced to retire from the task.
The [[Kappa]] is identified as a Japanese water demon in the textbook `//[[Fantastic Beasts and Where to Find Them]]//`. According to a lesson plan posted by [[Dolores Umbridge]] in the 1995-1996 school year, third-year students were meant to be reading about them, though it is unknown if this lesson took place under her supervision.
=====Behind the Scenes=====
  * In the `//Harry Potter and the Chamber of Secrets//` video game, a creature referred to as a "Water Demon" appears as a distinct enemy in a flooded section of the [[Hogwarts]] library's [[Restricted Section]]. This depiction is unique to the game and does not directly align with other known Water Demons. (video game)
  * The [[Kappa]] of the [[Wizarding World]] is taken directly from Japanese folklore, where it is a well-known water spirit or //yōkai// with very similar characteristics.
