Note: The episode is dedicated to Gardner Fox, a Golden and Silver Age comic writer who co-created both the Justice Society of America (JSA) and the Justice League of America (JLA), the comics on which the Guild --and this series, respectively -- are based.[4] Originally, the showrunners wanted to use the JSA, but DC Comics publisher Paul Levitz felt that the story was inappropriate, so they altered the names and designs of the team.

4317"Secret Society"Dan RibaStan BerkowitzNovember 22, 2003 (2003-11-22)
While the Justice League are quarreling about the value of mutual trust and teamwork, Grodd organizes a Secret Society composed of Giganta, Killer Frost, Sinestro, Parasite, Shade, and Clayface.

4519"Hereafter"Butch LukicDwayne McDuffieNovember 29, 2003 (2003-11-29)

A band of supervillains (composed of Metallo, Kalibak, Livewire, Weather Wizard, and Toyman) team up to get revenge on Superman. When they attack Metropolis, Toyman shoots an experimental weapon at Batman and an injured Wonder Woman, but Superman sacrifices himself to save them and is seemingly vaporized. The League attempts to cope with the loss of Superman by defending Metropolis in his absence, save for Batman, who does not believe Superman is truly dead and begins investigating on what actually happened. Eventually, Lobo arrives at the Watchtower and nominates himself as Superman's replacement, but he does more harm than good. Superman wakes up 30,000 years in Earth's future, but the sun has turned red, removing his superpowers. He encounters a humbled Vandal Savage, the only human left alive after an attempt at world domination staged a few months after Superman's disappearance. Savage reveals he had been working on a time machine, but he is immortal, and he cannot exist at the same time as his previous self as it would cause a paradox. Superman can go back to a time where he doesn't exist, i.e., after his 'death'. With knowledge of past Savage's crime, he goes back in time, reunites with the League and informs them of Savage's plot. Lobo is sent on his way. In the future, the desolate wasteland is replaced with people and a city as a thankful Savage disappears from existence.

Note: Writer Dwayne McDuffie wrote on his forum that the episode title "Hereafter" is a subtle pun: Part One shows the apparent death of Superman, which according to most religions would send his soul to some sort of "Hereafter." But as is later revealed, he had been sent to the future while remaining geographically in the same place (the future ruins of Metropolis), and was thus "here, after."[citation needed]
4721"Wild Cards"Butch LukicStan Berkowitz & Dwayne McDuffieDecember 6, 2003 (2003-12-06)

With his Gwynplaine Entertainment Company (a reference to The Man Who Laughs) the Joker takes over TV stations in Las Vegas, announcing that he has placed a series of bombs that will destroy the Strip in 22 minutes and 51 seconds if they are not stopped by the Justice League. With the whole world watching, the League must first get past the Joker's own super-team, the Royal Flush Gang. However, the threat imposed by the Joker is not as simple as it seems, and Batman must track down his location to stop him.

Note: This episode is notable as a 'hidden crossover' with Teen Titans, as the Royal Flush Gang is voiced by the five principal actors from that series. The gang's designs are also based on the Teen Titans voice actors.[7]

Note: Wonder Woman and Martian Manhunter make cameos on the computer monitors.
4923"Comfort and Joy"Butch LukicPaul DiniDecember 13, 2003 (2003-12-13)

Green Lantern engages in a snowball fight with Hawkgirl. Hawkgirl responds by starting an interplanetary barroom brawl. Batman spends Christmas on Watchtower duty.

After Earth is attacked by a Gordanian battleship, the League is aided by an army of Hawkmen from Hawkgirl's home planet of Thanagar. The Thanagarians offer to help Earth build a shield to defend against the Gordanians, but Batman discovers that this is just a ruse. Hawkgirl finds herself torn between her allegiance to Thanagar and her commitment to the Justice League, as well as between her betrothal to the Thanagarian commander Hro Talak and her budding romantic love for Green Lantern.

Note: Hro Talak is an anagram for Katar Hol, Hawkman's given Thanagarian name in the comic series.[citation needed]

Two spin-off comic book series (Justice League Adventures and Justice League Unlimited) were loosely set in the same continuity as the animated series. They feature characters who never appeared on the animated series such as Blue Beetle, Mary Marvel, Power Girl, Black Lightning and Firestorm and sometimes contradict events already shown, for example Wonder Woman remembering the events from "The Once and Future Thing".

Matt Wayne (who wrote "Chaos at the Earth's Core", "Flash and Substance", and "Patriot Act") wrote issues 37 and 38 of the comic, based on unused episode ideas.[8]
