John Falsworth

John Falsworth is a British nobleman who became the vampire Baron Blood, terrorizing wartime Europe before clashing with the Invaders during World War II. His aristocratic heritage and dark transformation made him one of Marvel's earliest supernatural villains.

Roy Thomas and Frank Robbins introduced John Falsworth to Marvel readers in The Invaders #9 in 1976, planting this Bronze Age creation firmly in the rich soil of World War II-era adventure. Over nearly five decades of publication, he's kept remarkable company — sharing pages with Captain America, Union Jack, Baron Blood, and the Human Torch — a roster that speaks to his place at the heart of Marvel's wartime mythology. With appearances across The Invaders, Captain America, and Avengers, and four collector-recognized key issues to his name, Falsworth is the kind of character that rewards the dedicated reader who digs deeper into Marvel's history. Twenty-one catalog appearances may sound modest, but in this corner of the Marvel universe, quality of company counts for everything.
