Wights are the evolved form of a hollowgast after it has consumed enough peculiars. They are the main antagonists of the Peculiar Children series and film adaptation: Miss Peregrine's Home for Peculiar Children (film).
A wight looks like a normal, except the fact that they have pure, milky-white eyes with no iris. Many also appear to be physically unremarkable and consequently can pass unnoticed by most, which also enables them to disguise themselves with little trouble. Wights are adept at passing unnoticed. A wight's ability to impersonate others so easily means that they are capable of alternating between various different disguises as the situation demands. Wights will often take jobs in the normal world, wearing colored contact lenses so that their unusual eyes do not arouse suspicion. In this way, a wight may watch over and become many different people in a peculiar's life, such as the case was with Mr. Barron during his observations of Jacob Portman; at different times posing as a school bus driver, a pool cleaner, a psychologist, and a bird watcher.
Wights do not have any peculiarities, nor do they retain the memories of their previous lives. In the film adaptation, they have varied peculiarites. Mr. Barron can shapeshift, make himself look like anyone he wants and can his change his right hand into a weapon of choice such as an axe, machete or knife; Mr. Gleeson has Cryokinesis, the ability to control and manipulate ice; and Miss Edwards is half-simian.
An exception to both these facts is Caul. He is able to turn into a peregrine falcon and also retains his memory.
Wights are the evolved form of hollowgasts. Once a hollow has consumed enough peculiars, its "hollow soul" is filled with the "second soul" located within the peculiar. Thus, it evolves into a wight.
Wights work for hollows. Wights aid hollowgasts in their transformation into wights by hunting down peculiars for them to feed on.
- According to Miss Peregrine, wights are fond of dramatic gestures, and invariably leave behind some taunting memento.
- In the film, wights retain their peculiarities.
- In the film, five of the peculiar scientists became wights. The rest remained hollowgasts.
- Miss Edwards is so far the only female wight in the film.
- The word wight is not mentioned during the film.
- In the film, hollowgasts only need to eat peculiars' eyeballs to evolve into wights. Horatio is the only hollow in the books to have consumed eyeballs.
