The first Sun Girl was created by artist Ken Bald and an unidentified writer. She first appeared in "Sun Girl" #1 (Aug. 1948), published by Marvel's 1940s precursor, Timely Comics. Sun Girl starred in a namesake three-issue series cover-dated August to December 1948. She subsequently co-starred in stories of the original Human Torch in "The Human Torch" #32-35 (Sept. 1948 - March 1949), "Captain America Comics" #69 (Nov. 1948), "Sub-Mariner Comics" #29 (Nov. 1948), and "Marvel Mystery Comics" #88-91 (Oct. 1948 - April 1949). She additionally starred in a solo story each in the first two of those "Marvel Mystery" issues. The Human Torch-Sun Girl story "The Ray of Madness" from "The Human Torch" #33 (Nov. 1948) was reprinted decades later in Marvel's "Giant-Size Avengers" #1 (Aug. 1974). Sun Girl appears in flashback in the final two issues of the four-issue miniseries "Saga of the Original Human Torch" (April–July 1990)
