[3] Writer Mike Conroy notes, "Arthur Parks was a scientist sufficiently proficient to design laser projectors small enough to wear on his wrists, quite the achievement in 1966.

The Living Laser met the Avengers again when he tried to conquer a small South American country, who defeated and incarcerated the villain.

[5] The Laser, after breaking out of prison by creating a laser using parts teleported to him, reappears as part of a team formed by master villain the Mandarin after being teleported to his base, in an unsuccessful attempt to destroy the Avengers and conquer the world, he attacked Africa to try stealing diamonds, but was defeated by Thor and Hawkeye despite the robot Ultimo being transported there from a volcano.

[7][8] The Laser reappears as part of the first version of the Lethal Legion gathered by the Grim Reaper in a failed revenge plot against the Avengers.

[10] The Laser eventually acquires the artifact the Serpent Crown, and while controlling the living weapon Nuklo and a battalion of the US Army attempts to conquer the world, but is defeated by the Avengers.

[11] He is then employed, along with fellow villains Power Man and Whirlwind, by Count Nefaria, who temporarily amplifies their abilities and sends them against the Avengers as the second Lethal Legion.

The plan, however, is stopped by Iron Man and in battle with the hero, the Laser's energy levels build to critical mass.

James Rhodes—Stark's friend and employee, currently acting as CEO and the new 'Iron Man' while Tony is apparently dead—tricks the Laser by offering him a position at the company before trapping him in a wide-beam communication chamber which disperses him across the Andromeda Galaxy, although Rhodes wonders if he did the right thing and even the Laser privately wondered if he would legitimately accept Rhodes' offer to return to a research role or just take it to destroy the company from within.

Upon receiving upgrades, Living Laser breaks Tony Stark's repulsor arc, causing him to go into cardiac arrest.

[24] Living Laser, Batroc the Leaper, and Whirlwind attack a haggard, bearded man in torn World War II army uniform who identifies himself as Steve Rogers.

[25] During the "Search for Tony Stark" arc, Living Laser rejoined Hood's gang and assisted in the attack on Castle Doom.

Parks refused to stop so Stark in his Iron Man suit was forced to destroy his containment armor causing his laser form to dissipate, killing him.
