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.
