The Body Controlling Curse is a Curse utilized to take over their opponents body.

Overview
The user turns their body into a black mist substance and enters their body through openings like the mouth or eyes. They then gain complete control of their host's body. Strong enough individuals can resist the Curse, but the one utilizing the Curse may be able to take over their body for split seconds at a time. The user can also give their power to their host increasing their overall magical or Curse power and allow them access to their abilities.
