In 1972 the Highway Safety Division of Virginia published a comic book for kids about bike safety called Danny and the Demoncycle . It stars a young sociopath named Danny who enjoys riding his bike in such as way as to cause the death of innocent people. He changes his ways after having a dream involving Satan and a "demoncycle" that takes him on a ride so wild that even Danny can't handle it. After that, he becomes an exemplary lad, following bicycle safety rules to the letter and admonishing anyone who doesn't.
This is the latest addition to the "Comics with Problems" library, curated by Ethan Persoff.
