Agent Brand

Bursting onto the scene in the pages of Astonishing X-Men #10 (2005), Agent Brand arrived during one of the most celebrated runs in Modern Age Marvel history, courtesy of the electric creative team of Joss Whedon and John Cassaday. She's the kind of character who makes an impression fast — two of her six catalogued appearances already carry key-issue status, a remarkable ratio that speaks to the significance of her debut arc. Sharing pages with heavy hitters like Cyclops, Emma Frost, and Logan, she entered Marvel's universe at the very highest table, and Astonishing X-Men remains her defining stage. For collectors who prize that era of sharp, cinematic Marvel storytelling, Agent Brand is an essential name to know.
