Marvel’s Captain America is famously rarely seen carrying a gun into battle, and instead relies on his trusty vibranium shield – but the creation of the shield is a Marvel mystery. Vibranium is exceedingly rare outside of Wakanda and thus the majority of the metal is carefully guarded, but a portion was reserved for the creation of Steve Rogers’ famous shield during World War II. Now Captain America: Sentinel of Liberty #3 reveals the reclusive creator of the shield has hidden a message directly on his creation – and Captain America only just now learns of it.
In the modern era, Captain America’s shield is the centerpiece of many stories, both in comics and in the Marvel Cinematic Universe. 2021’s United States of Captain America series involved a group of supervillains stealing Steve’s original shield, and using it to release Hate-Monger from his secret prison. The short series Falcon and the Winter Soldier on Disney+ also concerns the shield and Sam Wilson’s reluctance to carry the weapon. Finally, present-day Captain America discovers the shield is not merely a weapon, but a symbol – and not of freedom and patriotism, but oppression and fear.
In Captain America: Sentinel of Liberty #3, written by Jackson Lanzing & Collin Kelly with art by Carmen Carnero, Captain America travels to Germany only to discover the “clean energy plant” is a front for the mysterious Outer Circle, a clandestine organization that has shaped history. Steve Rogers learns of the Outer Circle through the mysterious Doctor Boka Agboje, who created and operated the vibranium forge that ultimately resulted in Captain America’s famous shield. This retcons an important question surrounding Rogers’ famous weapon: who exactly created the shield?
