Susan Scarbo

Born from the fertile imagination of Marvel's Silver Age, Susan Scarbo made her debut in the pages of Captain America #123 in 1970, stepping into a corner of the Marvel Universe populated by some of its most intense and morally complex figures — she shares the page with Captain America himself, the brutal Crossbones, and the shadowy Mother Night, among others. With affiliations spanning both the Avengers and Alpha Flight, she's a character who has touched two of Marvel's most beloved super-teams across a publishing history that stretches an impressive five decades to 2024. Her appearances are concentrated in the high-stakes world of Captain America and The Avengers, making her a figure woven into the fabric of Marvel's most enduring titles. Thirty catalog appearances may sound modest, but for dedicated collectors and continuity hunters, Susan Scarbo is one of those rewarding discoveries hiding in plain sight across half a century of Marvel history.
