The name Bodach is used to describe shadow-like creatures-invisible to most people-that appear at locations before disasters in the books Odd Thomas, Forever Odd, Brother Odd, and Odd Hours by Dean Koontz.
In various editions of the Dungeons and Dragons game, a monster called "Bodak" (spelling difference noted) appears as an undead who has been killed by "absolute evil" with a dark and shadowy mien and the ability to inspire fear.
