The Bookworm was a villain created for the 1960s Batman television series. The character was identifiable by his thick glasses and dark brown leather suit, made to match rare old book bindings. He had an affinity for books and centered many of his schemes around them. The character was first referenced as part of the mainstream Batman comic books in 1989's Secret Origins Special #1 and appeared, in a form dramatically different from his television counterpart, as an enemy of the Huntress in The Huntress #7-11. He has since appeared in his original television form, with a cameo on the animated Batman: The Brave and the Bold, and as the main villain in Batman '66 #6, a comic book based on the 1960s series.
