Invisibility

**Invisibility** was the power of being invisible, the state in which a physical object remained magically unseen by others.

## Examples of invisibility

### Wizardkind

> Harry looked down at his feet, but they were gone. He dashed to the mirror. Sure enough, his reflection looked back at him, just his head suspended in midair, his body completely invisible. He pulled the cloak over his head and his reflection vanished completely.

   A highly useful skill, invisibility could be harnessed by wizardkind, most notably by using an Invisibility Cloak, the Invisibility Potion or the Invisibility Spell. A Disillusionment Charm or ***Bedazzling Hex*** could also be cast to achieve virtual invisibility. The protective enchantment ***Cave inimicum*** would produce an invisible boundary over the caster, concealing them from view.

Wizards had also developed the Invisibility Charm, a spell used to render a target area invisible. They also developed the Invisibility Booster, a device which could turn an enchanted car, its passengers, and everything else inside invisible. Invisible Ink was a type of magical ink that transfigured writing to become invisible. Disappearing Ink would presumably write invisible text onto paper. ***Headless Hats*** were prank devices invented by Fred and George Weasley to make the wearer's head become invisible, in order to startle people.

There was also a section of books in the Hogwarts Library called the Invisibility Section. The books within this section discussed invisibility and were, appropriately, invisible.

### Creatures

Several magical creatures possessed various degrees of invisibility. Most notable include the ***Demiguise***, an orangutan-like ape, who could turn invisible at will, and the Thestral, who appeared invisible to anybody that hasn't witnessed and accepted the reality of death ***Poltergeists*** such as ***Peeves*** may have chosen to be invisible or not, an ability they may share with other non-beings. The ***Tebo*** and ***Hidebehind*** were also magical beasts who all had the ability to become invisible. The ***Wrackspurt*** was an invisible creature which could float into a person's ears, and make their ***brain*** go fuzzy, but could be seen with ***Spectrespecs***.

### Conditional invisibility

Certain creatures and items could become invisible to certain people while remaining fully visible to others at the same time; while compared to true invisibility, this ability seemed more akin to manipulation of the targets' minds. The most well-known example of this debatable form of invisibility were Thestrals, a type of skeletal ***winged horse*** known for being "invisible" to those who had not witnessed and comprehended death. Another example was ***bimetal alchemical thread***, a patented wizard-made magical fibre, invisible to practitioners of the Dark Arts. ***Dementors*** were invisible to ***Muggles*** and ***Squibs***, but visible to wizardkind.
