Lord Falsworth was the younger son of William, Lord Falsworth, one of the wealthiest figures in the British aristocracy during the late Victorian and Edwardian eras. Upon William’s death shortly before the outbreak of the First World War, the family title passed to the elder son, Montgomery, who also inherited a majority of the estate under the laws of primogeniture. Bitter over his exclusion, Lord John Falsworth left England for the European continent in search of fortune and power.
His travels eventually brought him to Romania, where he sought Castle Dracula, inspired by Bram Stoker’s 1897 novel Dracula. While most dismissed the book as fiction, Lord John believed the journals and letters within it were factual accounts of real events. Convinced that controlling Dracula would grant him immense wealth and influence, Lord John pursued the vampire; only to fall victim to Dracula’s hypnotic power. Dracula bit him, killing him; three nights later, John rose as a vampire himself. Recognizing John’s British origins as useful, Dracula sent him back to England to spread terror among the people there, particularly those associated with Abraham Van Helsing and other vampire hunters.
After World War I began, Lord John offered his services to German intelligence, adopting the codename, Baron Blood. Concealing his identity behind a grotesque bat-like costume and mask designed to inspire fear, Baron Blood became one of Germany’s most effective secret weapons during the final months of the war. He repeatedly battled the Freedom’s Five, a group of Allied costumed operatives from the United States, Great Britain, and France, but always escaped capture. In the war’s final weeks, he carried out a series of murders in London, targeting military leaders and other prominent figures. He was ultimately confronted by the original Union Jack, who was not only a member of the Freedom’s Five but also secretly Baron Blood’s brother, Montgomery. Union Jack wounded Blood with a silver blade, forcing him to flee England.
After World War I, Baron Blood devoted himself to the study of the occult. With Adolf Hitler’s rise to power, Blood again aligned himself with German intelligence, viewing the Nazi leadership as ideological kindred spirits. German scientists subjected him to painful experimental procedures that temporarily allowed him to withstand direct sunlight, though at the cost of diminishing some of his vampiric abilities, including shapeshifting. Under the assumed identity of John Falsworth, Jr., purportedly Lord John’s son, Blood returned to Falsworth Manor. To conceal his partially retractable fangs, he wore specially designed oversized dentures and avoided sunlight whenever possible, claiming to suffer from a rare skin condition.
Baron Blood soon resumed his reign of terror in England and nearly killed his brother’s daughter, Jacqueline, by biting her. This time, however, he was opposed not only by Montgomery, who emerged from retirement to become Union Jack once more, but also by the Invaders, a team of superhumans serving the Allied cause. Union Jack and the Invaders uncovered John Jr.’s true identity, and during the ensuing battle, Blood was impaled on a stalagmite containing traces of silver.
Months later, Baron Blood was resurrected and joined the Super-Axis, a group of superhuman agents serving the Axis powers. The full extent of his activities during World War II remains unknown. By the war’s end, however, he had again been killed, this time by a wooden stake through the heart, and owing to his aristocratic status he was entombed in the Tower of London. Dracula later returned to London and ordered his human pawn, Dr. Charles Cromwell, to resurrect Baron Blood. With the aid of fellow vampires, Cromwell infiltrated the Tower, removed the stake, revived Blood, and substituted another skeleton in his place.
After Dracula departed, Cromwell fell under Blood’s control. Blood learned everything he could about Cromwell’s medical practice and compelled him to relocate near Falsworth Manor. There, Blood began preying upon villagers while concealing his identity. When suspicious locals traced the attacks to Cromwell’s home and set it ablaze, Blood murdered Cromwell and his daughter, leaving their bodies in the burning house. Believing the vampire destroyed, the villagers abandoned the matter. In truth, Blood survived and assumed Cromwell’s identity. By this time, the effects of the German experiments had worn off, restoring his full vampiric powers. While disguised as Cromwell, he could still endure sunlight for limited periods by wearing a specialized mask and protective garments. He sustained himself by drawing small amounts of blood from Cromwell’s anemic patients.
Eventually, Blood’s compulsions forced him to resume killing. He ensured his victims were dead before draining them, preventing them from rising as vampires, and authorities attributed the deaths to a serial killer. The now elderly Lord Falsworth suspected his brother’s involvement and summoned Captain America, who had previously fought Baron Blood as a member of the Invaders. Unbeknownst to him, Blood was still masquerading as Dr. Cromwell and was serving as his personal physician, waiting for the moment to turn his frail brother into a vampire and condemn him to eternal weakness.
Captain America soon discovered that the skeleton entombed in the Tower was not Baron Blood’s and confronted him shortly thereafter. Lord Falsworth’s grandson, Kenneth, uncovered Blood’s impersonation of Cromwell, and during the ensuing battle Captain America decapitated Baron Blood with his shield. Blood’s head and body were burned separately, and their ashes scattered in different locations to prevent any future resurrection. With the later casting of the Montesi Formula, even those ashes were dematerialized, ensuring Baron Blood’s final and absolute destruction.
