- For the Star Trek: Shabonee episode, see "The Boogeyman".
The Boogeyman was an entity encountered by the USS Shabonee (NCC-64332) crew in 2370, named as such by one of the children aboard the ship. It could take both corporeal and non-corporeal form.
After several reconnaissance sweeps past the Shabonee, the Boogeyman disabled the ship, leaving it drifting in space on emergency power. Many crew and civilians were stranded in various parts of the ship, while others were paralysed with fear by horrific visions caused by the entity. First officer Penelope Koh assembled a team, including chief engineer Michael Greene and counselor Daniel Radke, to counter the Boogeyman, driving it away to regain control of the ship.
