Uncanny X-Men #29

Uncanny X-Men number 29 was published in March 1967 as part of the original Silver Age run of the series created by Stan Lee and Jack Kirby. At this stage in the title's history, the team was struggling with declining sales, a common issue for the book throughout the mid-1960s, which led the editorial team to experiment with various villains and high-concept plots to capture reader interest.

The issue features artwork by Werner Roth, who took over pencils from Kirby, working under the pseudonym Jay Gavin. Roth brought a more traditional, grounded illustrative style to the X-Men compared to the dynamic, cosmic aesthetic established by Kirby. In this story, the X-Men face the alien Mimic, a character whose ability to replicate the powers of others served as a narrative device to explore the group's internal dynamics and the persistent theme of the team's search for identity in a world that feared them.
