A Hover Ghost is a humanoid creature with white skin clad in a black coat with gold cuffs. It wears white gloves on its large, long-fingered hands, which are not directly connected to the Heartless's body and can be "thrown" at enemies. A few holes in the coat expose the creature's ribcage. Its Heartless emblem is printed on the front of its coat. The Hover Ghost's spherical head sports a jagged mouth and two yellow eyes with black spirals in them. Its right eye hangs down from its socket, attached to its head by a silver chain. It can generate spotlights from its eyes, suggesting that they may be mechanical in some fashion. The Hover Ghost's lower body is a simple, ghostly tail.
The Hover Ghost's name reflects its ability to levitate as well as its appearance, which resembles that of a stereotypical ghost. Its Japanese name, "Leer Ghost", has several possible meanings. "Leer" can refer to a malicious sideways look one gives to another, referring to the Heartless's beacon and dangling eye. It could also refer to a state of extreme wanting, which could, in turn, be a reference to ghosts that linger on because of intense worldly desires.
