The X-Men #64
The X-Men #64 (January 1970) is the debut of Shiro Yoshida — Sunfire — making him Marvel's first Asian superhero and one of the earliest non-white heroic figures in the company's publishing history. Writer Roy Thomas deliberately rooted Shiro's origin in the atomic bombing of Hiroshima, tying the character's mutant identity directly to one of the 20th century's defining tragedies and pushing the X-Men's core metaphor — that mutation and societal trauma are inseparable — to its most explicit expression yet. Though the original series ended just two issues later and lapsed into reprints, Sunfire's introduction planted the seed for the franchise's internationalist reinvention: he was recruited for the landmark Giant-Size X-Men #1 (1975) team, making this issue a quiet hinge point between the Silver Age original roster and the Bronze Age 'All-New, All-Different' era that would transform the X-Men into Marvel's dominant franchise.

Roy Thomas had wanted to introduce a Japanese mutant character during his very first run writing the X-Men in the mid-1960s, but editor Stan Lee declined without giving a specific reason; Thomas shelved the idea and did not revisit it until he returned to the book alongside Neal Adams in 1969. By the time #64 was produced, Adams had departed — leaving Don Heck to handle interior pencils, with Tom Palmer's inks doing significant heavy lifting to maintain visual continuity with the high-energy Adams issues immediately preceding it; a cover by Sal Buscema (inked by Palmer) completed the package. The issue landed as the title was in its final weeks of producing original material, with new stories ceasing at #66 before a years-long reprint run began — giving Sunfire the unusual distinction of debuting in a series that was, editorially, already on its way out.
