The original Lethal Legion are formed by the villain Grim Reaper (the brother of Avenger Wonder Man) and consisted of Man-Ape, Power Man, Living Laser, and Swordsman. Man-Ape attacks Captain America, but is beaten back by the Avengers. However, he captures the Black Panther's girlfriend Monica binding her hand and foot with metal clamps. Black Panther is lured into a trap by Man-Ape, and despite getting past him he is knocked out by an exploding dummy of Monica. Black Panther is chained and with Man-Ape, he meets the other members of the Lethal Legion.[2]
Grim Reaper dispatched the Lethal Legion members to different locations to meet the Avengers. Power Man and Swordsman were sent to the water main below Avengers Mansion, Living Laser and Man-Ape were sent to the nearby power station, and Grim Reaper seemingly departed to Greenwich Village. Black Panther broke free and contacted the Avengers to warn them about the Lethal Legion's plot. Grim Reaper returns and uses the knockout gas in his scythe to knock out Black Panther while revealing that he planned to have the Avengers lured to the locations of which Black Panther knew about. While the other members of the Lethal Legion defeat the different Avengers, Vision defeats Power Man (who had been sent to capture him at Avengers Mansion). He disguises himself as Power Man and Power Man as him and takes him to the base. The Lethal Legion places the Avengers in an hourglass container and then fills it with deadly gas. When "Power Man" arrived with "Vision," Grim Reaper detected the brain patterns of Wonder Man and shattered the hourglass to save Vision's life only to realize that the vision in the hourglass was actually Power Man. At that point, Vision aided the Avengers into defeating the Lethal Legion who are handed over to the authorities.[3]
A second version, formed by European villain Count Nefaria reappears in the title, composed of Living Laser, Whirlwind and Power Man. He magnifies their powers, but is revealed to be a manipulative ploy to steal their magnified powers in a failed bid to destroy the Avengers. The depowered villains are sent to prison.[4]
The Grim Reaper returns in the title West Coast Avengers, leading a third version against the superhero team consisting of Black Talon (Barone), Goliath, Man-Ape, Nekra, and Ultron-12. Grim Reaper has Ultron lead a squadron of robots to spring Goliath from a compound that he is imprisoned in. When Goliath is freed by Man-Ape, the three villains work together to take out the Avengers as Ultron-12 states that he has his own plans for Wonder Man. The three villains escape with an unconscious Henry Pym and Wonder Man. Hawkeye figures out that Grim Reaper is behind this.[5]
The three villains meet up with Grim Reaper. Internal squabbling and personal agendas overtake the villains and they are defeated and scattered.[6]
In the title Avengers West Coast the demonSatannish creates another version using the souls of four infamous historical killers that were found in Mephisto's section of Hell. They have been given powers along with Hangman and the group battle the renamed Avengers West Coast. The group consisted of Axe of Violence (a demonically-enhanced version of Lizzie Borden with an axe replacing one hand), Coldsteel (a demonically-enhanced version of Soviet leader Joseph Stalin, now an 8 ft. giant with superhuman strength), Cyana (a demonically-enhanced version of Lucrezia Borgia with poisoned claws), and Zyklon (a demonically-enhanced version of Nazi official Heinrich Himmler who can belch deadly gas fumes from his mouth). This incarnation eventually lost their powers and their souls were destroyed during the struggle between Mephisto and Satannish.[8]
A new version of the Lethal Legion appears during the "Dark Reign" storyline in the three-issue limited seriesDark Reign: Lethal Legion. The Grim Reaper (now aided by his brother Wonder Man) recruits villains to oppose criminal mastermind Norman Osborn.[9]
Absorbing Man, Grey Gargoyle, Mister Hyde, and Tiger Shark later reformed the Lethal Legion and end up fighting the Avengers.[10]
Each of its members were revealed to have been saved from their approaching deaths in exchange that they partake in his contest against Challenger.[12]
When Challenger reveals his secret player in the form of a resurrected Hulk, most of the Lethal Legion are defeated with Hulk breaking Captain Glory's spine and presumably killing Mentacle.[13]
After the contest is ended by the Avengers, the Lethal Legion regrouped and fled to Knowhere. As they have nowhere to return to after each one's near-death experience, the Lethal Legion decides to stay together and see what they can accomplish.[14]
Count Nefaria forms another version of the Lethal Legion which now consists of Grey Gargoyle, Living Laser, and Whirlwind. The group raids a Project Pegasus facility to look for the Catalyst so that Count Nefaria can regain his powers. He revealed to the scientist that mentioned it was relocated that he got a copy of the information from Chameleon as the scientist knows the Catalyst's full potential. Count Nefaria kills the scientist with his abilities so that he won't tell anyone how to stop him. When Whirlwind and Living Laser stated to Count Nefaria that he should be resting, Count Nefaria stated that he needed the exercise.[15]
At Empire State University, Dr. Curt Connors reveals the Catalyst to the crowd when the Lethal Legion attacks. While Grey Gargoyle and Whirlwind attack the people present, Living Laser helps Count Nefaria to operate the Catalyst. Spider-Man shows up and has a hard time fighting them due to the fact that his mind was focused on what a revived Sin-Eater did to Overdrive. Sin-Eater shows up and starts using the same gun he used on Overdrive on Whirlwind and Grey Gargoyle while taking their powers. Immobilizing Spider-Man with Grey Gargoyle's powers, Sin-Eater proceeded to do the same thing to Living Laser and Count Nefaria. All four of them were sent to Ravencroft where they started to act like model inmates. Norah Winters was allowed by Norman Osborn to interview them about Sin-Eater.[16]
As a side-effect of Sin-Eater's suicide upon copying Madame Web's precognition revealed that Kindred was using them, the Lethal Legion regained their sins and are among the villains that went on a rampage.[17]
After having separated himself from Ultron upon his defeat, a fragment of Hank Pym's conscious recreated his body in an older appearance and worked with Black Ant into killing villains (consisting of Blizzard, Bullet, Cobra, Lodestone, Mortar of the Bastards of Evil, Oddball, Piecemeal, Speed Demon, Sunstroke, and Supercharger) with his ant projectiles and reviving them into his Lethal Legion in order to prepare for Ultron's return while faking their deaths. Wasp and Moon Knight learned the truth when they finally encountered Hank Pym. The "Victor Shade" persona that Hank Pym put into Whirlwind's body gets hijacked by Ultron-12 as he knocks Hank out. As Wasp remembers that Ultron-12 is the "good Ultron", she learns from him that he only knocked out Hank to protect him from the Lethal Legion as Ultron takes control of them. In the nick of time, Ant-Man, Mayor Luke Cage, Nadia van Dyne, Stinger, Valkyrie, and Vision show up to help fight the possessed Lethal Legion. When Ultron was defeated and Ultron-12 creates a new body for himself that he calls Mark Twelve, the Lethal Legion recover as they leave with Hank to regroup in Sub-Atomica and prepare for Ultron's return as part of Protocol S.[18]
The Lethal Legion appears in Marvel's Guardians of the Galaxy, led by Captain Glory and consisting of the Blood Brothers. This version of the group are bounty hunters and associates of Lady Hellbender.
