Demon

"Wrestled with werewolves, defied demons, battled beasts, Gilderoy's bewildering bravery never ceases to amaze in this, yet another magical masterpiece."

- Year with the Yeti by Gilderoy Lockhart

The demon is an apparently malelovent magical creature. Known demons are Kelpies, Kappas and Grindylows, which are classed as "water demons".

Gilderoy Lockhart was said to have "defied demons" on his travels, and Fred and George Weasley sold a product called the Demon Box, which contains a savage demon.
