The Unicorn is an enemy in Castlevania: Curse of Darkness. It is a legendary animal which has its origins in Greek mythology. It is usually depicted as a white horse with a spiraling long horn protruding from its forehead, which, as legends say, has healing properties.
The Unicorn is a legendary animal that has been described since antiquity as a beast with a large, pointed, spiraling horn projecting from its forehead. Unicorns are not found in Greek mythology, but rather in the accounts of natural history, for Greek writers on this matter were convinced of the real existence of unicorns, which they located in India, a distant and fabulous realm for them.
In European folklore, the unicorn was often depicted as a white horse-like or goat-like animal with a long horn and cloven hooves (sometimes with a goat's beard). In the Middle Ages and Renaissance, it was commonly described as an extremely wild woodland creature, a symbol of purity and grace, which could only be captured by a virgin. In the encyclopedias, its horn was said to have the power to render poisoned water potable and to heal sickness.
Instead of the classic depiction of a horned horse, in Castlevania: Curse of Darkness the Unicorn is instead an enemy that resembles a human with the head of a unicorn. It has a mainly human body and a purple-furred horse head with a thick white mane. It carries a book that it uses to attack, usually by summoning harmful runes or by projecting blades from its pages (much like the Magic Tome from Symphony of the Night and the Tome of Arms in Portrait of Ruin).
