Willie Wormwood (or Willy Wormwood; also know as Bondo Bitter) is a Thimble Theatre character created by E. C. Segar. He appeared in the earliest strips as the dastardly villain to Harold Hamgravy‘s hero and Olive Oyl’s damsel, wherein they would enact short dramas and movie parodies in a format that lasted only for the early run of the comic.
Willie was an old-fashioned villain, suave, well-dressed and mustachioed. He was eventually dropped from the series before the introduction of more popular characters like Castor Oyl and, several years later, Popeye. However, he makes a return appearance as late as 2012 in the second issue of IDW Publishing’s Popeye comic series, titled “The Worm Returns“. There he is portrayed as a vaudeville actor who vies with Popeye for Olive’s affections, with ulterior criminal motives.
