Batman has Robin. Captain America has Bucky. And Yankee Doodle had Dandy. Being a superhero is hard work, which is why so many comics characters rely on a sidekick for help. But just as not every superhero achieves the glory of Batman, not all sidekicks are as capable as the Boy Wonder. In The League of Regrettable Sidekicks, author Jon Morris discusses some of the strangest iterations of the sidekick phenomenon, and in the process explores how important these characters were to comic book storytelling. Drawing on the entire history of the medium, The League of Regrettable Sidekicks celebrates characters and stories that haven't seen the light of day in decades, pulling from defunct and long-forgotten comics publishers as well as DC and Marvel.
