History
Grim Reaper's Lethal Legion
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.
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.
Count Nefaria's Lethal Legion
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.
Grim Reaper's second Lethal Legion
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.
The three villains meet up with Grim Reaper. Internal squabbling and personal agendas overtake the villains and they are defeated and scattered.
Porcupine's Lethal Legion
A fourth version appears in the title Marvel Age. They were led by the Porcupine and consisted of Attuma, Batroc the Leaper, Bulldozer, Black Tiger, Kurr'fri of the Saurians, Gorilla-Man (Nagan), Piledriver, Sabretooth, Thundra, Trapster, Unicorn, Whirlwind, and Wrecker. The Lethal Legion tracked down and battle Captain America who is aided by several other Marvel heroes. Their battle with the superheroes was witnessed by the Beyonder. The outcome of the battle was not shown, but it is assumed that the heroes won.
