Bat Boy is a fictional creature who made numerous appearances in the American supermarket tabloid Weekly World News, beginning with a front page story in 1992.

His pursuers, according to Weekly World News, are scientists and United States government officials; he is frequently captured, then later makes a daring escape.

The original front-page photo of Bat Boy, showing his grotesque screaming face, was the second-best selling issue in the tabloid's history, and he has since evolved into a pop-culture icon.

According to the cartoon, Bat Boy is currently hitchhiking with a typical American family after resigning from being the President of the United States (and King), has placed Weekly World News columnist Ed Anger under arrest and saying goodbyes to Beyoncé, a half sasquatch (with whom he was romantically involved), and Dr. Ron.

A musical based on the Bat Boy character premiered at Tim Robbins' Actors Gang Theatre on Halloween, 1997 and has since been produced Off Broadway, in London's West End, and in scores of productions throughout the world.
