WONDER WOMAN #9 (Oct 1987)
DC Comics

Excerpt:

The New Cheetah
Writers George Pérez and Len Wein introduced a different version of the Cheetah in 1987 with “Wonder Woman” No. 7 (the series restarted from No. 1 earlier that year). Here, Barbara Minerva is a greedy and selfish archaeologist who forces an African tribe to perform a ritual on her, hoping it will give her immortality. Instead, she receives the ability to transform into the catlike Cheetah, gaining superhuman strength and speed; the ritual partially backfires, and her human form becomes frail and weak. As a result, she can only live up to her true potential as the Cheetah.
