The first series was a 12-issue comic book limited series co-written by Dan Abnett and Andy Lanning, often collectively referred to and interviewed as "DnA", penciled primarily by Oliver Coipel, with Pascal Alixe filling in for some issues, inked by Lanning, and colored by Tom McCraw.
The series replaced "Adventure Comics" as the second Legion title published by DC Comics as part of The New 52 and focuses on a small group of the original incarnation of Legion of the Super-Heroes (and Earth-247 Legionnaire Gates) as they are stranded in the present-day 21st Century, having failed to stop a shape-shifting terrorist from Rimbor from infecting Earth with a deadly virus.
[2] Following the destruction of the Legion Outpost base by a tear in the fabric of space, Saturn Girl, Brainiac 5.1, Chameleon, Umbra, Kid Quantum, Live Wire, Apparition, and Monstress find themselves lost on the far side of the universe.
[4][5] As they cross the galaxy, the Legion discovers that the Progeny have been actively slaughtering entire species in genocide, inspired by their radical belief that they are the "perfect" life form.
[4][6] They also encounter a mysterious superhero known as Singularity and a creature known as the Omniphagos, a world-destroying monster imprisoned in a "hard light" pyramid.
While she claims she was trying to keep the team levelheaded and calm, the revelation that Apparition was merely a psychic illusion designed to pacify Ultra Boy turned the group against Saturn Girl.
[12] Element Lad explains that in trying to save the team as they came through the rift, he was cast back to the beginning of time and that he has now lived for over a billion years.
[13] A battle erupts, and the Legion eventually escapes by way of a dimensional gateway Element Lad possesses—the hard light pyramid they had discovered earlier.
[14] Each issue of Legion Lost was narrated by a particular Legionnaire: #1 Shikari, #2 Monstress, #3 Kid Quantum, #4 Apparition, #5 Brainiac 5, #6 Umbra, #7 Ultra Boy, #8 Chameleon, #9 Saturn Girl, #10 Wildfire, #11 Element Lad, and #12 Live Wire.
Singularity would rally the entire galaxy against the remaining members of the Progeny, who would find themselves hunted by their former victims and systematically wiped out by them.
The surviving members of the species would find a shocking ally in Live Wire, who ended up merging with a dying Element Lad, transforming him into a crystallized entity.
The second series, part of The New 52, depicts seven Legionnaires (Chameleon Girl, Dawnstar, Gates, Timber Wolf, Tellus, Tyroc, and Wildfire) from the post-Infinite Crisis "Retroboot" Legion trapped in the twenty-first century pursuing a villain who released a pathogen.
[16] Tellus telepathically searches the world for people infected by the pathogen when they hear a news report of an attack from a marrow-sucking creature.
The individual members of the team are attacked and defeated by:Rose Wilson, Psykill, Misbelief, Windstorm, Ridge, Hammerfist, and Crush.
Tellus, controlled by Alastor, attacks the squad that had captured Tyroc and Chameleon Girl before he passes his consciousness among various soldiers and Legionnaires in the area.
He is a Zuunian and the son of scientist Mar Londo, who gave him his powers to protect him from the criminal Lord Vykor before being killed.
Captain Nathaniel Adym tells her of various prophecies and ancient findings: Tyroc dying a millennium before he was born, Wildfire's faceplate found in the Arizona desert, and Gates' disregard for authority, along with his conspiracy theories.
Responding to a beacon, the Legion finds a member of the Science Police, Nathaniel Adym, who has come to the present to assign a new mission to the team.
Lacking firepower, Adym sends a distress signal to Echo agent Jocelyn Lure, who arrives with Superboy, Caitlin Fairchild, and Ridge.
Adym plans to use his Time Bubble to travel back an hour and set off a bomb, which would destroy half of the continent but stop Daggor's machine and save the future.
