Captain America & The Falcon: Madbomb

In this 2004 one-shot from Marvel, Jack Kirby returns to the character he co-created, delivering a single-issue story that revives the classic "Madbomb" concept from his 1970s Captain America run. The issue pits Captain America and the Falcon against a chilling plot involving a device that incites mindless rage, showcasing Kirby's signature explosive action and larger-than-life storytelling. Though a brief entry, it serves as a nostalgic capstone to Kirby's legendary tenure with the star-spangled Avenger.
