This spell is a Human Transfiguration spell that transfigures a human into a bat. According to Kennilworthy Whisp, this is one of the few ways wizards may fly unaided, but it is inconvenient due to the fact that a bat does not possess the memory required to remember where one wanted to fly in the first place.[1]


In a 1994 letter to his godfather Sirius Black, Harry Potter noted that the Dursleys were still being uncommonly nice to him that summer because they feared Sirius may suddenly appear and use this spell on them should they misbehave Harry.[2]

Behind the scenes

  • It is unknown if this spell is specifically to turn humans into bats, or if it could turn any creature (and possibly inanimate objects) into a bat.
