Wonder Woman made her debut in All-Star Comics at the end of 1941 and on the cover of a new comic book, Sensation Comics, at the beginning of 1942, drawn by an artist named Harry G. Peter. She wore a golden tiara, a red bustier, blue underpants and knee-high, red leather boots. She was a little slinky; she was very kinky. She’d left Paradise to fight fascism with feminism, in “America, the last citadel of democracy, and of equal rights for women!”
A warning that is first heard from the lips of Cheetah as she attempts to escape captivity, yet is echoed by others around the globe, all putting Wonder Woman on alert. As she attempts to investigate, she is attacked by Supergirl, wanting vengeance for the death of Rao, as the influence has gotten to her as well. An epic battle breaks out, and once again, the trusty Lasso of Truth saves the day, though barely.
Trevor pitched a mission to destroy the facility where the gas was being created, but his superiors decided against it, stating that it was too late in the war to do something as drastic as that. When Trevor argued that more soldiers would die, his superiors simply stated that that was what soldiers did. With the battle of Themyscira and the death of her aunt so fresh in her mind, Diana was infuriated by the man's comments and berated him, calling him a coward and telling the rest of the council that they should be ashamed. Trevor escorted her out as she ranted, apologizing to the council on her behalf.
Wonder Woman and the other heroes were finally released from the Firestorm Matrix when Batman used the Lasso of Truth on Firestorm. Superman was still infected with the Kryptonite shard inside his nervous system, but Lex Luthor was able to extract it, saving Superman's life. Luthor also assembled a group of villains that defeated the Crime Syndicate. Later, at the Batcave, Wonder Woman and the Justice League talked about the enemy that destroyed the Crime Syndicate's world and came to the conclusion that Darkseid would return.
