The Agent

Stepping out of the mutant-packed pages of The X-Men Annual #1 in 1992, The Agent is a Copper/Modern Age Marvel creation brought to life by the powerhouse trio of Fabian Nicieza, Jim Lee, and P. Craig Russell — a debut pedigree that alone makes this character worth a second look. With a catalog footprint spanning all the way to 2022 and appearances alongside heavy-hitters like Wolverine, Omega Red, and Mojo, The Agent clearly occupies a corner of the Marvel universe where the stakes run high and the company is anything but ordinary. One of those appearances carries key-issue status, making that original Annual a worthy addition to any serious collection. Rare doesn't always mean forgotten — sometimes it just means waiting to be rediscovered.
