With a new decade arriving, DC president Jenette Kahn ordered a revamp in Wonder Woman's appearance. Artist Milton Glaser, who also designed the "bullet" logo adopted by DC in 1977, created a stylized "WW" emblem that evoked and replaced the eagle in her bodice and debuted in 1982. The emblem in turn was incorporated by studio letterer Todd Klein onto the monthly title's logo, which lasted for a year and a half before being replaced by a version from Glaser's studio. With sales of the title continuing to decline in 1985 (despite an unpublished revamp that was solicited), the series was canceled and ended in issue #329 (February 1986) written by Gerry Conway, depicting Steve Trevor's marriage to Wonder Woman.
Demeter, the goddess of agriculture and fertility, blessed Diana with strength drawn from the Earth spirit Gaea, making her one of the physically strongest heroes in the DC Universe and the strongest female hero in the DC Universe. This strength has allowed her to easily overwhelm Superman and Supergirl. She has also held her own against Darkseid. Her strength has no measurable limits and she can break the Chronus Scepter, which is universal in its destructive power. However, now Diana is the daughter of Zeus, king of the Greek Gods, so it is unclear as to how much of her power and strength is a direct result of her divine heritage. Her connection to the earth allows her to heal at an accelerated rate so long as she is in contact with the planet. However, as mentioned earlier, now that she is a demigoddess, it has been suggested that she heals extremely quickly also due to her divine heritage. In rare cases where she has been gravely injured, Diana showed the ability to physically merge with the earth, causing whatever injuries or poisons to be expelled from her body; such an act is considered sacred, and can only be used in extreme cases.
Many writers have depicted Diana in different personalities and tone; between both of her diametric extremes; that of a worldly warrior, a highly compassionate and calm ambassador, and sometimes also as a naive and innocent person, depending on the writer. What has remained constant, and is a mainstay of the character, is her nurturing humanity: her overwhelming belief in love, empathy, compassion, and having a strong conscience. This trait had been the reason for her induction into the Star Sapphires.
In the following days, Diana soon uncovered Ares, who exposed her to be the God Killer, having been originally conceived to be the ultimate weapon against her brother. Following this revelation, a fierce battle ensued, where Diana fulfilled her purpose in freeing mankind from Ares' influence. The loss of Steve in World War I had left Diana sobered, but she vowed to protect humanity whenever she was needed, albeit in a cautious and distant way.
Diana sees Sir Patrick Morgan in the base, who reveals himself to be the true Ares, and tells her of his plan for a world without humanity by having them destroy each other. Ares proposes that Diana help him accomplish his vision of paradise, but Diana promptly refuses, not wanting to kill billions of innocents. Ares then reluctantly engages her in an epic battle while Steve and his comrades attempt to dismantle the plane harboring the mustard gas.
