Ronin

The Ronin identity first appeared as a mysterious masked figure operating in Japan, deliberately designed to conceal the hero beneath the costume. Marvel introduced the persona as a way for a skilled hero to act covertly, unaffiliated and unnamed — a true 'ronin,' a warrior without a master.

Few identities in Marvel's Modern Age carry as much mystique as Ronin — a figure who stepped onto the scene in 2005 and has since accumulated 77 catalog appearances across series as iconic as New Avengers, Siege, and Captain America. The sheer company this character keeps — Wolverine, Luke Cage, Ms. Marvel, Peter Parker — speaks to a place right at the heart of Marvel's modern superhero landscape, rubbing shoulders with some of the House of Ideas' heaviest hitters. With three key issues to their name and a publishing presence stretching all the way to 2026, Ronin is no footnote — this is a character with real staying power and collector significance. If you're tracing the connective tissue of Marvel's Modern Age, Ronin is a name worth knowing.
