The X-Men #10

The X-Men #10 was published by Marvel Comics in March 1965, during the mid-1960s period often referred to as the Marvel Age of Comics. Created by writer Stan Lee and artist Jack Kirby, the issue serves as a notable entry in the original series, featuring the debut of the villain Ka-Zar in the Savage Land. This period was characterized by Lee and Kirby's efforts to expand the Marvel Universe's geography, introducing hidden, prehistoric pockets of the world that would become staples of X-Men lore.

Jack Kirby provided the cover and interior art, employing his signature kinetic and blocky aesthetic that defined Marvel's visual identity at the time. The story sought to shift the X-Men's focus away from the urban environment of the Xavier Institute and into more exotic, adventurous settings. As part of the early run of X-Men, the issue is remembered today primarily for its role in establishing the long-term thematic importance of the Savage Land in subsequent decades of X-Men storytelling.
