Legion of Super Heroes is an American animated television series produced by Warner Bros. Animation, adapted from the DC Comics series of the same name. It debuted on September 23, 2006, and centers on a young Superman's adventures in the 31st century, fighting alongside the eponymous group of superheroes. The show was produced by one of its main character designers James Tucker, a co-producer of the Justice League Unlimited series, for the Kids' WB line on The CW network.

The series drew on the rich history of the Legion of Super-Heroes, taking inspiration from stories set during all time periods of the team's nearly 50-year history in comics. Continuity is internally consistent but is not shared with any previous incarnation of the Legion, either animated or in print. It also had a tie-in spin-off comic book series, Legion of Super-Heroes in the 31st Century, that lasted 20 issues.

The series was cancelled after its second season.[1]

Development history

A few months before Legion of Super Heroes premiered, the Legion appeared in the Justice League Unlimited episode "Far From Home". The episode featured Supergirl traveling to the future and joining the Legion, leading audiences to think that it was intended to serve as a back-door pilot establishing a premise for the Legion show, and that it would be a DCAU spin-off. However, series producer James Tucker clarified that Legion's show was deliberately created from scratch:

Let's get the myths out of the way. The Legion series was never tied to the Justice League Unlimited episode. Supergirl was never, ever going to be in the Legion. The true origin of the series came out of Cartoon Network's desire to have a Superman-centric series to premiere when the movie Superman Returns premiered. Superman as part of the Legion worked for them. So the series was originally developed for Cartoon Network, then they passed and Kids' WB! stepped in. They, too, wanted a Superman-centric series with Superman fresh out of Smallville, learning to be Superman. That's the reality.[2]

Early reports had suggested the title of the series would be Superboy and the Legion of Super-Heroes, but the official announcement in April 2006 confirmed the title as Legion of Super Heroes. The same announcement indicated that the series would air on the Kids' WB block of the new The CW network at 10 a.m.[3]

Legal status/issues

At the 2006 Comic Con International, the production staff did not officially say whether legal issues at the time involving the ownership of Superboy had affected this series or whether changes were made to tie the series in with the Superman Returns film, but one significant change had been made since the announcement of the series. The original press release referred to "the young Superboy",[4] while the revised press release, published in June, described the character as a young Superman. At the conclusion of the pilot episode, Clark adopts the superhero name of Superman, and not Superboy. In the second season, which takes place two years after the end of the first season, the character is called Superman, without reference to his "young" status.

Second season

The second season has a darker and more mature tone than the first season and mostly focuses on Brainiac 5 and his relationship with his evil ancestor, the original Brainiac. In the second season, most of the Legionnaires have changed their appearances, e.g., Lightning Lad has longer hair and gains a robotic arm after Imperiex blasted off his right arm during a battle. Additionally, Triplicate Girl changes her codename to Duo Damsel because her white self was lost in a temporal anomaly during a battle in the 41st century. The series logo was also slightly revised.[5] As with the first season, a total of 13 episodes were created for the second season, which premiered on September 22, 2007. The show was not renewed for a third season.[1]

Proposed third season

A third season had been planned for production but was dropped because 4Kids Entertainment over the Kids' WB! slot. It would have taken place three years after the end of the second season in which an older Superman would return. Sensor, Wildfire, Magnetic Kid, Supergirl, Tellus, Princess Projectra and Shadow Lass were to be introduced, while background characters Blok and Dawnstar would have active roles. Kell-El was intended to be a regular character but with a reduced role (with Wildfire planned to be his replacement). The main focus of the third season would have been Brainiac 5's return, while trying to redeem himself after the second season's finale and the evil Brainiac 6 trying to destroy the Legion. Also, producer James Tucker planned to make an episode adaptation of the story "The Ghost of Ferro Lad" to introduce Ferro Lad's long-lost twin brother.[6] The final episode of season two linked the two seasons together.[7][8]

The first season of the series began airing on Cartoon Network UK on March 5, 2007. The 13 episodes were shown weekdays through March 21, and the two-part season finale aired in the UK about five weeks before it was shown in the US. It also used to air on CITV 'Action Stations' and re-aired on Cartoon Network Too.


From left to right: Bouncing Boy, Saturn Girl, Brainiac 5, Superman, Phantom Girl, Timber Wolf, and Lightning Lad.

In the first season, the series revolved around a core group of eight Legionnaires but others appeared from time to time in recurring roles, similar in format to the Justice League Unlimited animated series.


The first season introduces a teenaged Clark Kent who is about to move from Smallville to Metropolis. He knows of his abilities but does not know what to do with his future (similar in nature to the Clark Kent featured in the Smallville television series). After traveling to the future, young Clark assumes the identity of Superman and gradually learns to control his abilities, becoming the hero he is destined to be. At the end of the first season, he returns to the present around the same time he left in the first episode.

In the second season, Superman returns to the future after spending two years in the past and gaining more experience with his powers. Also, Superman X, a clone of Superman from the 41st century created to battle Imperiex, is introduced. When Imperiex travels back to the 31st century, Superman X is forced to follow him into the past and recruit the Legion to help him.

Core Legionnaires

Series producer James Tucker offered descriptions of the core team in a July 2006 interview at Comic Con International in San Diego.[9] As with other DC team shows such as Justice League Unlimited, not every core character appears in all episodes. The following descriptions apply to the characters as seen in the first season.

Other Legionnaires

XS appears in the finale "Dark Victory" as a background character. Dawnstar and Invisible Kid also make cameo appearances in the finale, along with many other rarely seen Legion members.

In the first season, some Legionnaires were mentioned or shown as images before making an actual appearance. Fourteen members were shown during the season as already active: Blok, Bouncing Boy, Brainiac 5, Colossal Boy, Cosmic Boy, Dream Girl, Element Lad, Lightning Lad, Phantom Girl, Saturn Girl, Shrinking Violet, Sun Boy, Triplicate Girl, and Tyroc. Five more joined the Legion through the course of the series: Superman, Timber Wolf, Matter-Eater Lad, Star Boy, and Ferro Lad.

The opening credits sequences used for first-season episodes included a glimpse of the Mission Monitor Board signs for many Legionnaires as well as shots of flying Legionnaires who would be seen in later episodes (though not all of those with Mission Monitor Board symbols appeared). At least four members of the Legion as seen in the comics appeared in some way on the show but had not joined by the end of the first season (Ultra Boy, Lightning Lass, Wildfire, and Polar Boy).

In the second season, Karate Kid appeared in the opening credits with the other Legionnaires, though he did not appear until the fifth episode (in which Nemesis Kid also became a new member). Similar to Karate Kid, Sun Boy appeared in the second season opening titles and made semi-regular appearances but did not have a speaking line or have someone else refer to him by name. Ayla Ranzz, sister of Lightning Lad, finally made an appearance, but without apparent super powers and not as the Light Lass of the comic books.

Legion of Super Heroes in the 31st Century

A comic book based on the show's continuity was published under the title Legion of Super-Heroes in the 31st Century. According to the comic's writer, J. Torres, the name was chosen to distinguish itself from more specifically youth-oriented titles such as Justice League Adventures and Superman Adventures.[18] The first issue was distributed during Free Comic Book Day 2007 in addition to being sold.

An interview concerning the Legion of Super Heroes in the 31st Century comic confirmed that the comic was to continue publication despite the series ending, and that the comic would also be telling stories that were to have taken place after the second-season finale.[19] As of issue #20, the comic ceased publication.[20]

Additional characters

While the comic incorporates the cast of the show, other characters from DC Comics have made an appearance.

Collected editions

Issues #1–7 were collected in the trade paperback Legion of Super Heroes in the 31st Century, Vol. 1: Tomorrow's Heroes (March 2008, ISBN 978-1-4012-1668-9).


A tie-in promotion with McDonald's Happy Meal took place in August 2007, containing eight figurines: Superman, Timber Wolf, Lightning Lad, Brainiac 5, Bouncing Boy, Mano, Tharok, and Validus.

Action figures by Mattel were not produced because of a lack of retailer interest.[21]

The collectible miniatures game HeroClix produced a special starter set of the Legion, including a figure of "Young Superman" during the first season.
