Legion

A creature of the Copper/Modern Age, this Legion burst onto the scene in 1997's X-Men #1 — a key issue right out of the gate — courtesy of Fabian Nicieza, Reinhard Schweizer, and Andy Kubert, published through Panini Deutschland. With only a handful of catalog appearances, Legion is a rare and intriguing presence, sharing pages with heavy-hitters like Scott Summers, Logan, Bobby Drake, and even the savage Sabretooth. Scarcity has its own appeal in comics collecting, and stumbling across this character in the wild feels like a genuine find for fans who love digging into the corners of the X-Men universe.
