Union Jack

Union Jack is a patriotic British hero who operates during World War II, fighting alongside the Invaders — including Captain America, Namor, and the Human Torch — as a flag-costumed combatant relying on skill and courage rather than superhuman powers.

Few characters embody Marvel's wartime patriotic spirit quite like Union Jack, the flag-draped British hero who stormed onto the Bronze Age scene in The Invaders #9 in 1976, courtesy of Roy Thomas and Frank Robbins. Born from that era's deep affection for Golden Age adventure and World War II mythology, Union Jack has shared the page with some of Marvel's most legendary figures — Captain America, Namor, and the Human Torch among them — keeping genuinely august company across titles like The Invaders and Captain America: War & Remembrance. With two key-issue appearances to their name and a publishing presence stretching across an impressive 34 years, this is a character whose staying power speaks for itself. If you love Marvel's rich wartime corner of the universe, Union Jack is absolutely worth tracking down.
