The Legion of Super-Heroes is a superhero team appearing in American comic books published by DC Comics. Created by writer Otto Binder and artist Al Plastino, the Legion is a group of superpowered beings living in the 30th and 31st centuries of the . The group was formed after being inspired by Superboy (Clark Kent)'s feats and they aim to keep the universe safe by protecting it from the threats of multiple enemies. They first appeared in Adventure Comics #247 (April 1958).

The team is closely associated with the original Superboy (Clark Kent) character and in their first appearances was portrayed as a group of time travelers. Later, the Legion's origin and back story were fleshed out, and the group was given its own monthly comic.

Initially Superboy's role as the inspiration for the formation of the Legion and their multiple adventures together were retconned in the 1990s by editorial mandate as a consequence of the editorial decision at that time to eliminate the origin of Superman as Superboy. In the 2000s, the origin of Superman as Superboy was restored once the editorial ban was lifted, resulting in the classic origin of the Legion being created because the founding Legionnaires were inspired by Superboy's exploits in Smallville to be considered canon once again. The multiple adventures together in the future of the Legion of Super-Heroes with Superboy (Clark Kent), Supergirl, Conner Kent and later Jon Kent, are also considered to be canon.

The team has undergone two major reboots during its run. The original version was replaced with a new rebooted version following the events of the Zero Hour: Crisis in Time! storyline in 1994 and another rebooted team was introduced in 2004. A fourth version of the team, nearly identical to the original version, was introduced in 2007. In 2019, DC announced a new series written by Brian Michael Bendis and drawn by Ryan Sook.

Publication history Original continuity (1958–1994)

Superboy was the featured series in Adventure Comics in the 1950s. In Adventure Comics #247 (April 1958) by writer Otto Binder and artist Al Plastino, Superboy met three teenagers from the 30th century: Lightning Boy, Saturn Girl, and Cosmic Boy, who were members of a "super-hero club" called the Legion of Super-Heroes. Their club had been formed with Superboy as an inspiration, and they had time travelled to recruit Superboy as a member. After a series of tests, Superboy was awarded membership and returned to his own time.

Although intended as a one-off story focusing on Superboy, the Legion proved so popular that it returned for an encore in Adventure Comics #267 (December 1959). In this story, Lightning Boy had been renamed Lightning Lad, and their costumes were close to those they wore throughout the Silver Age of Comic Books. The Legion's popularity grew, and they appeared in further stories in Adventure Comics, Action Comics, and other titles edited by Mort Weisinger over the next few years. The ranks of the Legion, only hinted at in those first two stories, was filled with new heroes such as Chameleon Boy, Invisible Kid, Colossal Boy, Star Boy, Brainiac 5, Triplicate Girl, Shrinking Violet, Sun Boy, Bouncing Boy, Phantom Girl, Ultra Boy, and Supergirl.

In Adventure Comics #300 (September 1962), the Legion received their own regular feature, cover-billed "Superboy in 'Tales of the Legion of Super-Heroes'". While they shared space with Superboy solo stories for a couple of years, they eventually displaced Superboy from the title entirely as their popularity grew. Lightning Lad was killed in Adventure Comics #304 (January 1963) and revived in issue #312 (September 1963).McAvennie, Michael "1960s" in Dolan, p. 108: "The demise of the Legion co-founder was a first not only for the Legion fan base, but for mainstream comics in general...Lightning Lad was resurrected later that year in Adventure Comics #312."

It was the Adventure Comics run which established the Legion's general workings and environment. A club of teenagers, they operated out of a clubhouse in the shape of an inverted yellow rocket ship which looked as if it had been driven into the ground. The position of Legion leader rotated among the membership. Each Legionnaire had to possess one natural superpower which no other member possessed; despite this, several members had overlapping powers, particularly Superboy, Supergirl, Mon-El, and Ultra Boy. Some issues included comical moments where candidates with bizarre, useless, or dangerous abilities would try out for membership and be rejected; five of these candidates went on to form the Legion of Substitute Heroes. The Legion was based on Earth and protected an organization of humans and aliens called the United Planets alongside the Science Police. The setting for each story was 1000 years from the date of publication.

In Adventure Comics #346 (July 1966), Jim Shooter, 14 years old at the time, wrote his first Legion story.McAvennie "1960s" in Dolan, p. 118: "In his first-ever published story, fourteen-year-old Jim Shooter admitted four new members into the Legion of Super-Heroes ... Shooter's long, memorable tenure as one of the Legion's greatest writers was officially underway." Soon thereafter, Shooter became the regular writer of the Legion stories, with Curt Swan, and later Win Mortimer, as artist. Shooter wrote "The Death of Ferro Lad", in which Ferro Lad was killed—the first "real" death of a Legionnaire (although Lightning Lad had been believed dead for a while before). Shooter introduced many other enduring concepts, including the Fatal Five,McAvennie "1960s" in Dolan, p. 123: "Writer Jim Shooter and artist Curt Swan unleashed an even greater menace when the Fatal Five decided to stay united in the years ahead." Karate Kid, Princess Projectra, Shadow Lass, the Dark Circle, Mordru, and the "Adult Legion", a possible future version of the Legion.

The Legion's last appearance in Adventure Comics was #380 (May 1969), and they were displaced by Supergirl in the next issue. The early 1970s saw the Legion relegated to the status of back-up feature. First, the team's stories were moved to Action Comics for issues #377–392 (June 1969 – September 1970). Following Mort Weisinger's retirement from DC, the Legion was passed to the oversight of editor Murray Boltinoff and began appearing occasionally as a backup in Superboy, starting with #172 (March 1971), with writers E. Nelson Bridwell and Cary Bates and artist George Tuska. Dave Cockrum began drawing the series with Superboy #184 (April 1972), again increasing the team's popularity.McAvennie "1970s" in Dolan, p. 151: "After more than a year as Murphy Anderson's background inker, Dave Cockrum landed his big DC break as the Legion of Super-Heroes artist ... Cockrum's debut story, which was written by Cary Bates, quickly established an exciting new vibe for the super-team."

Superboy and their own title

The first comic book published under the title Legion of Super-Heroes was a four-issue series published in 1973 that reprinted Legion tales from Adventure Comics. In the same year, the Legion returned to cover billing on a book when Superboy became Superboy starring the Legion of Super-Heroes with #197 (August 1973). Crafted by Bates and Cockrum, the feature proved popular and saw such events as the wedding of Bouncing Boy and Duo Damsel in Superboy #200 (Feb 1974).McAvennie "1970s" in Dolan, p. 159: "Bouncing Boy and Duo Damsel became the first Legionnaires to tie the knot. The wedding planners were writer Cary Bates and artist Dave Cockrum." Issues #202 (June 1974) and #205 (Dec. 1974) of the series were in the 100 Page Super Spectacular format. Cockrum was replaced on art by Mike Grell as of issue #203 (August 1974) which featured the death of Invisible Kid.McAvennie "1970s" in Dolan, p. 160: "With the unenviable task of replacing the departing Dave Cockrum, one of the most popular artists ever to draw the Legion of Super-Heroes, Mike Grell's first issue on Superboy starring the Legion of Super-Heroes killed off one of the team's most beloved members." With #231 (September 1977), the book's title officially changed to Superboy and the Legion of Super-Heroes and also became a "giant-size" title. At this point, the book was written by longtime fan Paul Levitz and drawn by James Sherman, although Gerry Conway frequently wrote as well. Saturn Girl and Lightning Lad were married in All-New Collectors' Edition #C-55 (1978), a treasury-sized special written by Levitz and drawn by Grell.McAvennie "1970s" in Dolan, p. 177: "Only an oversized treasury edition could have contained Superboy and the entire Legion of Super-Heroes' battle with the Time Trapper...and the long-awaited wedding of Lightning Lad and Saturn Girl...Legion favorites Paul Levitz and Mike Grell were up to the enormous challenge with the popular tale 'The Millennium Massacre'." In #241–245 (July–December 1978) Levitz and Sherman (and then Joe Staton) produced what was at that time the most ambitious Legion storyline: "Earthwar", a galactic war between the United Planets and the Khund, with several other villains lurking in the background. During this period, Karate Kid was spun off into his own 20th century-based self-titled series, which lasted 15 issues. Levitz left the book, to be replaced full-time by Gerry Conway.

Superboy departed from the Legion due to a villain's plot, and the book was renamed simply The Legion of Super-Heroes starting with issue #259 (January 1980). Editor Jack C. Harris hired Steve Ditko as guest artist on several issues, a decision which garnered a mixed reaction from the title's readership. Jimmy Janes became the regular artist in a lengthy tale by Conway (and later Roy Thomas) involving Ultra Boy's disappearance during a mission, and his long odyssey to rejoin the team. This story told the tale of the Legionnaire Reflecto (only glimpsed during the "Adult Legion" stories in Adventure Comics), featured villainy by the Time Trapper and Grimbor the Chainsman, and saw Superboy rejoin the team.

Paul Levitz era Paul Levitz returned to write the series with #284. Pat Broderick and Bruce Patterson illustrated the title for a short time before Keith Giffen began on pencils, with Patterson, and then Larry Mahlstedt, on inks. The creative team received increased popularity following "The Great Darkness Saga",Manning, Matthew K. "1980s" in Dolan, p. 198: "When [Levitz] wrote "The Great Darkness Saga", a five-issue epic that pitted the Legion against one of the most notorious villains of DC's long history, he and artist Keith Giffen crafted the most famous Legion story of all time and became fast fan favorites." which ran from #287; #290–294; and Annual #3, featuring a full assault on the United Planets by Darkseid. Comics historian Les Daniels observed that, "Working with artist Keith Giffen, Levitz completed the transformation of Legion into a science-fiction saga of considerable scope and depth."

The Legion celebrated issue #300 (June 1983) by revisiting the "Adult Legion" storyline through a series of parallel world short stories illustrated by a number of popular Legion artists from previous years. The story served to free up Legion continuity from following the "Adult Legion" edict of previous issues.

Giffen's style changed abruptly a few issues later, to a darker and sketchier style inspired by Argentinian artist José Muñoz. A new Legion of Super-Heroes comic (the third publication under the title) was launched in August 1984. It used a new "deluxe" printing format utilizing Baxter paper instead of the cheaper newsprint that classic comics had always been printed on. The existing Legion series, still on newsprint and renamed Tales of the Legion of Super-Heroes with issue #314, continued running new material for a year, then began reprinting stories from the new Legion of Super-Heroes with issue #326. Tales continued publishing reprints until its final issue, #354 (December 1987).
