Heartbreakers Meet Boilerplate

From 2005 onward, IDW published this single-issue crossover uniting two creator-owned properties by Anina Bennett and Paul Guinan. The story brings together the all-female superhero team the Heartbreakers with Boilerplate, the retro-futuristic steam-powered robot, for a lighthearted adventure. It's a charming, standalone curiosity that showcases the duo's affection for pulp-era heroics and historical whimsy.
