A Demiguise is a peaceful beast, according to Fantastic Beasts and Where To Find Them by Newt Scamander. They are found in the Far East, however, it is difficult to spot them because of their ability to make themselves invisible when they feel threatened. Since they are also able to predict immediate future events, it makes this creature hard to capture.
A Demiguise resembles an ape with fine silvery hair, which hides its big black eyes. The pelts of Demiguises are valued because they can be woven to make Invisibility Cloaks. The Ministry of Magic classifies these creatures as XXXX, meaning that they are fairly dangerous.
Demiguise contains the Latin root demi-, meaning half. It also contains the word guise, that which conceals the true nature of something. This name is fitting because a Demiguise can conceal itself by becoming invisible. Additionally, their ability to predict the future, which is always half-concealed and varying based on certain conditions, also makes this name relevant.
