Aaron Fischer

Aaron Fischer is a young Marvel hero who took up the Captain America mantle, wielding the shield as a symbol of hope for society's most vulnerable and marginalized communities, including runaway and homeless youth.

Bursting onto the scene in 2022's Captain America: Sentinel of Liberty #1, Aaron Fischer is a fresh Modern Age Marvel creation from the collaborative vision of Jackson Lanzing, Collin Kelly, and artist Carmen Carnero. His debut dropped him straight into elite company — sharing pages with Captain America, Sam Wilson, Wolverine, Spider-Man, and even Namor — a remarkable introduction for a new character. With appearances stretching into Astonishing Iceman alongside his core Captain America titles, Aaron has already shown a range that hints at a growing presence in the Marvel universe. For readers who love getting in on the ground floor with a character clearly being built for something bigger, Aaron Fischer is exactly the kind of discovery that makes modern collecting exciting.
