Comic books were more or less invented in 1933 by Maxwell Charles Gaines, a former elementary school principal who went on to found All-American Comics. Superman first bounded over tall buildings in 1938. Batman began lurking in the shadows in 1939. Kids read them by the piles. But at a time when war was ravaging Europe, comic books celebrated violence, even sexual violence. In 1940, the Chicago Daily News called comics a “national disgrace.” “Ten million copies of these sex-horror serials are sold every month,” wrote the newspaper’s literary editor, calling for parents and teachers to ban the comics, “unless we want a coming generation even more ferocious than the present one.”
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.
