best justice league animated episode fandomwire

Another DC Animated series that still stands the test of time. Justice League was a two season series between 2001 and 2004 and had a secondary series Justice League Unlimited. A series that was a worthy follow up to its previous entries Batman: The Animated Series and Superman: The Animated Series. At the time of this series, we had already been introduced to The Flash and the establishment of the Green Lanterns. Which left this series with the chance to write origin stories and world building for the rest of the League including Wonder Woman, Martian Manhunter, and Hawkgirl. Similar to its predecessors, Justice League also redefined and added onto these characters mythology that translated into the comic pages and future video game, television and film installments. So let’s dive into this amazing series and talk about some of the most memorable episodes, covering only ten of the best stories.


Season 1: Episodes 1, 2, 3 – Secret Origins

Secret Origins


Kicking off the list with the first three episodes that started it all. Secret Origins shows astronaut J. Allen Carter return from a space mission to Mars that sets off a chain of events that force the earths heroes to come together and face this threat. The world has begun betting all of their chips onto the Man of Steel but suddenly our planet is invaded by an unknown alien species. Batman and Superman attempt to be at the front lines of the battle but when Superman starts receiving unknown telepathic visions, he finally answers the call. Batman follows Superman to a military base where they find a Martian by the name J’onn J’onzz, who has come to here to warn us of the coming invaders. Just as they are about to leave the facility, they are met with soldiers of the alien armada. Overwhelmed by these invaders, J’onn telepathically summons Flash, Green Lantern, Wonder Woman and Hawkgirl and the forming of the Justice League is born. The League work together to bring down this intergalactic threat, destroying their planted manufacturing facilities and conquering over the foreign trespassers. With a new and bold take on the already established DC Animated Universe, Secret Origins was the story that got us excited and ready for more that was to come.


Season 1: Episodes 16, 17 – Legends



A reimaging of the Justice Society of America, Legends was an exciting and ambitious story that ended up taking a dark turn. After a battle with Lex Luthor fires a weapon that sends our heroes are sent to an alternate reality. Green Lantern, Flash, Hawkgirl and Martian Manhunter are put into a version of the 1960’s and with it a group of Superheroes known as the Justice Guild or America.

There is so much to love about this episode, the return of Lex Luthor and Joker, the appearance of diverse villains, the battle between heroes and villains. Everything about it works, and makes it for such a fun and entertaining episode. Not to mention if there is ever anything involving Mark Hamill voicing the Joker, you can count us in.


Season 1: Episodes 20, 21 – A Knight of Shadows

A Knight of Shadows


Although Jason Blood and his hellish counterpart Etrigan first made their appearance in The New Batman Adventures during the episode A Demon Within, it was this episode that fleshed out the character and told his origin story. During Medieval times, the sorceress Morgaine Le Fay attempts to overthrow Camelot and dub her son Mordred ruler over the Kingdom. Using Jason Blood as a pawn, she betrays him and inflicts a disease on him. But before he is killed by the infection the wizard Merlin appears and curses Blood with immortality and the shared duality with the Demon Etrigan.

Jason Blood and Batman work together with the help of Wonder Woman, Flash and Martain Manhunter to find the stones before La Fay does. What made this episode so intriguing was the moral dilemma J’onn J’onzz faces throughout the episode. After J’onn tries to telepathically locate the sorceress, she fires back at him and causes hallucinations of his deceased family. Many instances where the League could have victory are at times jeopardized because of the constant manipulation La Fay has on the Martian. To the point where he is willing to serve her and bring the stones too her. Luckily, he realizes the reality of his actions and instead of giving her the stone he destroys it and stops La Fay from achieving her goals.

In this time-bending episode, the League returns from a space mission to find that their world has been altered and is being run by a dictator named Vandal Savage. After being saved from this time’s version of Batman who has created a resistance army. They learn that the events that caused the present to change were the loss the United States faced in World War II. In an effort to change the present, the League travels to the past during the war to try and change their reality in the present.

Season 2: Episodes 17, 18 – Secret Society

Secret Society


What might come off as just another villains attempt to destroy the Justice League, this one comes with a bit more internal and personal struggle. Our heroes who work so close and tightly starts causing them to tear apart and not work as efficiently as they are use too. Meanwhile, Gorilla Grodd returns and has formed a new team of villains formed by the likes of Sinestro, Giganta, Parasite, and Killer Frost.

Now with the proper training and a full line up, the Secret Society lure the League together and manage to overcome them. Defeated and confined, Grodd display the League at a football stadium during a game for the world to behold the beaten heroes. Something I have mentioned before is how well this show made these characters human, even the ones that are aliens. Representing in a way the relationship between siblings and how we might not always get along with them, but they are still family and despite the difference we may face we can still work together and overcome obstacles.


Season 2: Episodes 19, 20 – Hereafter



Something about these characters and stories in an alternate world just works so well.

Superman makes the ultimate sacrifice and is vaporized, now with the greatest champion the world is left hopeless.

Season 2: Episodes 15, 16 – The Terror Beyond

The Terror Beyond


I feel this episode is often overlooked, but has some of the best character development of the series. When Aquaman resurrects Solomon Grundy, the League believe Aquaman has gone rouge. To discover what is afoot, they follow Aquaman to the Tower of Fate where they are met by Doctor Fate. An alliance between the King of Atlantis, Grundy and Fate has been made. Grundy has agreed to help Fate and participate in a ritual that would close a portal to a place that holds a being named Icthultu and his followers. In return, Fate will turn Grundy back into his human self who is known as Cyrus Gold. When the League arrive to discover the ritual taking place, they unknowingly interrupt it and cause the portal to be open and the creatures to be unleashed. The heroes attempt to fight back and keep the monsters from entering our world. Meanwhile, Grundy and Hawkgirl attempt to defeat the massive Icthultu. Grundy finds his way inside the monster and manages to kill it, but sacrifices himself in the process. The heart of this episode lies with the relationship between Grundy and Hawkgirl. Two characters who are often misunderstood, but are showed different perspectives in this episode. When you think Solomon Grundy is just a mindless brute, turns out he has feelings and desires. Hawkgirl who is often considered brutal and at times heartless, is compassionate and caring.


Season 2: Episodes 11, 12 – A Better World

These episodes ended up becoming a major plot point for future episodes leading into Justice League Unlimited. A reiteration of the comic book story Crisis on Two Earths, this episode gives us this shows a version of the Crime Syndicate with the Justice Lords. A version of the Justice League from another reality, where Lex Luthor has become the President and Superman has finally had enough and kills Luthor.

Season 2: Episodes 24, 25, 26 – Starcrossed



What was intended to be the series finale before the sequel series Justice League Unlimited. Starcrossed was the episode that changed everything in the series and almost encouraged you to go back and revisit both seasons. When an alien ship attacks the White House. It is quickly shot down by another ship and on it the leader of the Thanagarian Army, Hro Talak. Shortly after, Hawkgirl approaches him and it is discovered that she has a relationship with Talak and has been working as a spy to study Earth’s defenses, to make sure they are prepared for an attack by an alien species known as the Gordanians. So as Earth and the Thanagarians begin working together to prepare for an attack, it is also revealed that it’s all been a plot by the Thanagarians to weaken our planet’s defenses and take over. Betrayed by Hawkgirl, the League is taken into custody and the Thanagaraians declare martial law. Our heroes manage to escape but have to remain undercover in their alternate identities.

This is one of the most brutal and intense episodes of the series, the betrayal of Hawkgirl is unexpected and the position she puts the League in is the kind of writing that makes this show such an incredible and memorable show.
