The X-Men #19
The X-Men #19 (April 1966) is the debut of Calvin Rankin, the Mimic — the first non-mutant to wield the X-Men's combined power set and, more remarkably, the first outsider ever admitted to the team's ranks in subsequent issues. The issue also introduces Vera Cantor, Hank McCoy's long-running civilian girlfriend, whose decades-long presence in the Beast's supporting cast grounded his personal life across the Silver and Bronze Ages. As the final numbered issue written by Stan Lee before Roy Thomas took over scripting with #20, it serves as an unofficial curtain call on the founding era of the title, making it a genuine turning-point in the book's early history.
In "Lo! Now Shall Appear—The Mimic!", the X-Men face their most unsettling challenge yet when a mysterious stranger named Calvin Rankin effortlessly copies their abilities, leaving Bobby and Hank stunned. After a tense encounter with Jean at a restaurant and a dramatic pursuit to his hidden mine lair, the team confronts Calvin’s shocking origin—and a machine built by his father that could change everything. Written by Stan Lee and illustrated by Jay Gavin with inks by Dick Ayers, this 1966 classic features a cover by Werner Roth and Marie Severin, capturing the moment of revelation with bold, dynamic flair.

Stan Lee scripted the story — the last of his uninterrupted run on the series — while Werner Roth handled the interior pencils, working under the pseudonym 'Jay Gavin' (taken from the names of his two sons) to conceal his Marvel freelance work from his DC editors; Dick Ayers inked. Jack Kirby, whose cover layouts had defined the book's visual identity, is credited as the cover layout artist for this period. Marie Severin later made alterations to Mimic's wings and hands in the printed art, as documented by the Grand Comics Database. The issue shipped with a cover date of April 1966 and an on-sale date confirmed by the Library of Congress 1966 Periodicals records.
