Following Pérez, William Messner-Loebs took over as writer and Mike Deodato became the artist for the title. Messner-Loebs introduced Diana's Daxamite friend Julia in Wonder Woman vol. 2 #68 during the six-issue space arc. Messner-Loebs's most memorable contribution to the title was the introduction of the red-headed Amazon Artemis, who took over the mantle of Wonder Woman for a short time. He also included a subplot during his run in an attempt to further humanize Diana by having her work for a fictional fast food chain called "Taco Whiz".
Diana lifts a tank ready to crush Doctor Poison with it, but hesitates when she thinks about the love and compassion that Steve brought to her life when she realizes that he professed his love for her before leaving to sacrifice himself. Dropping the tank, Diana spares Doctor Poison, telling Ares that he is wrong about humanity. She tells him that while humans are everything Ares says and can be capable of the worst crimes, she's learned that they are equally capable of so much more: unbridled love and compassion. Ares engages Diana in a final fight, but is defeated after she fully embraces her powers as the God Killer and blasts Ares with powerful divine lightning. The soldiers, free from Ares' corruption, stop their fighting, thereby finally ending the war.
In 1954, Dr. Fredric Wertham alleged that there were lesbian subtexts to Wonder Woman and claimed comics contributed to juvenile delinquency in his book Seduction of the Innocent where despite a very obvious heterosexual relationship with Steve Trevor, Wertham asserted that Wonder Woman’s association with the Holliday Girls could be interpreted as a lesbian relationship. The Comics Code Authority was then introduced in reaction to Wertham 's claims against the entire industry.
