Argentine business tycoon Sebastian Ballesteros becomes the fourth Cheetah, as well as the only male Cheetah. He is an agent of the Amazon's enemy, Circe, as well as her lover. He seeks the plant god Urzkartaga to become a new version of the Cheetah, a supernatural cat-creature like Barbara Ann Minerva. Appealing to the plant god's ego, Sebastian makes the case that the previous Cheetahs have failed in their actions and that a male Cheetah could be superior. Once Urzkartaga is convinced, Barbara Ann Minerva's access to the Cheetah is cut off and Sebastian is given the power in her place. Later, Sebastian proves responsible for turning Wonder Woman's old friend, Vanessa Kapatelis, into the third Silver Swan. Angered at the loss of her powers, Barbara Ann Minerva eventually battles Ballesteros for control of the power of the Cheetah by becoming the temporary host of Tisiphone, one of the Eumenides or Furies. Minerva accesses this new power by stealing it from the Furies' former host, Helena Kosmatos, the Golden Age Fury. This does not assist her in regaining the right to become the Cheetah. Ultimately (off-panel) Minerva finally kills Sebastian in his human form, regaining her Cheetah form as a result. She is later seen giving his blood to the Urzkartaga plant as a sacrifice.
Cheetah arrived at Diana and Steve's house and quickly found Aphrodite, who was sitting and reading The Island of Dr. Moreau. Cheetah soon recognized who Aphrodite was, and asked her or passage to Themyscira. When Aphrodite denied her, Cheetah remarked that all immortals think they're better than humanity. She then asked Aphrodite to tell her she was beautiful, before stabbing her with the God Killer.
During 1942 to 1947, images of bound and gagged women frequently graced the covers of Sensation Comics and Wonder Woman. In Wonder Woman #3 (Feb.-March 1943), Wonder Woman herself ties up several women, dresses them in deer costumes and chases them through the forest. Later she rebinds them and displays them on a platter. In addition, Diana is rendered powerless if a male manages to chain her bracelets together. The comic's sexual subtext has been noted, leading to debates over whether it provided an outlet for Dr. Marston's sexual fantasies or whether it was meant (perhaps unconsciously) to appeal to, and possibly influence, the developing sexuality of young readers.
An illusion of Priscilla Rich appears in the second story arc of the comic book based on the Wonder Woman TV series, though she never had any appearances in that television series. She, along with several other enemies, was created by Doctor Psycho in order to battle Wonder Woman. Cheetah exclaims, "I've waited decades for this moment", implying that she had battled Wonder Woman in the 1940s. Later in the series, Barbara Ann Minerva becomes the Cheetah in an origin similar to that of her New 52 counterpart. Her source of power is revealed to come from the Egyptian goddess Mafdet. After a battle with Wonder Woman, she is taken into custody. Later, she reappears having escaped imprisonment. She convinces Clayface to attack Wonder Woman in order to restore his health. Cheetah is then seen working alongside the Riddler, Killer Croc, Clayface, and Mr. Freeze as part of Ra's al Ghul's League of Shadows. Together, the group ambushes Wonder Woman, Batman, Catwoman, Batgirl, and Nightwing in Arkham Asylum.
A modernized version of Priscilla Rich appears as one of the primary antagonists of the Wonder Woman feature in Wednesday Comics. Here, she is portrayed as a young archeologist from a wealthy Baltimore family who relies on enchanted artifacts to grant her superhuman abilities. She initially befriends a young Diana (before she has become Wonder Woman) after meeting her, but soon reveals her treacherous nature when she kidnaps Diana's friend Etta and uses her as bait for a trap set by Doctor Poison. In the end, both Priscilla and Poison are defeated by Wonder Woman.
After Jimenez, Walt Simonson wrote a six-issue homage to the I Ching era, in which Diana temporarily loses her powers and adopts an all-white costume (Wonder Woman vol. 2, #189–194). Greg Rucka became writer with issue #195. His initial story arc centered upon Diana's authorship of a controversial book and included a political subtext. Rucka introduced a new recurring villain, ruthless businesswoman Veronica Cale, who uses media manipulation to try to discredit Diana. Rucka modernized the Greek and Egyptian gods, updating the toga-wearing deities to provide them with briefcases, laptop computers, designer clothing, and modern hairstyles. Rucka dethroned Zeus and Hades, who were unable to move with the times as the other gods had, replacing them with Athena and Ares as new rulers of the gods and the underworld. Athena selected Diana to be her personal champion.
The first woman to become the Cheetah, in Wonder Woman #6 (October 1943), is Priscilla Rich, a 1940s-era blonde Washington, D.C. debutante of aristocratic upbringing who also has an overwhelming inferiority complex and suffers from a split personality and self-importance. After being eclipsed by Wonder Woman at a charity event and failing to kill her during an escapology act, Priscilla retreats to her room and collapses before her makeup mirror. There she sees an image of a woman dressed like a cheetah. "Horrors!" she cries, as she gazes at her evil inner-self for the first time. "Don't you know me?" replies the reflection. "I am the REAL you—the Cheetah—a treacherous, relentless huntress!" The image commands her to fashion a Cheetah costume from a cheetah-skin rug. "From now on," intones the reflection, "when I command you, you shall go forth dressed like your TRUE self and do as I command you..." The Cheetah frames Wonder Woman for a robbery by hiding the money in her apartment and tipping off the police, then sets fire to a warehouse Wonder Woman is in, although Wonder Woman escapes. She is presumed dead, but survives thanks to her fireproof costume.
When she has matured into an adult, Menalippe, the Oracle of the Amazons sees a vision in which the Gods and humanity is in danger from Ares. Soon they are approached by the Gods and tasked with organizing a tournament in order to chose a champion, who will save them from impending Doom. Diana competes against her mother's wish and win. Athena then sends her a weapon, the Lasso of Truth forged by Hephaestus from the girdle of Gaea.
That question merits a two-part answer. The first version of the Cheetah, the Priscilla Rich one, is almost as old as Wonder Woman herself. Diana’s co-creators, William Moulton Marston and H.G. Peter, introduced their heroine in 1941 and Cheetah in 1943. In other words, she’s part of the original canon, right alongside the villains of the first Wonder Woman movie, Ares and Doctor Poison. But the Barbara Ann Minerva version was introduced in 1987 as part of writer-artist George Pérez’s legendary run on Wonder Woman. Either way, she’s not a spring chicken in the history of comics.
