Human Bomb (Roy Lincoln)

Roy Lincoln was originally a scientist working with his father on a special explosive chemical called "27-QRX." However, when Nazi spies invaded his lab and killed his father, he resorted to ingesting the chemical to prevent it from falling into their hands. As a result, Lincoln gained the ability to cause explosions in any object he came into contact with, particularly through his hands; the only way to control it was to always wear special asbestos gloves (which were subsequently retconned into "Fibro-wax" gloves after the human health hazards of asbestos were discovered). Donning a containment suit to prevent any accidental explosions, Lincoln became the "Human Bomb," removing his gloves only to expose his explosive powers against Nazi and Japanese enemies, as well as ordinary criminals. He later gained enough control over his powers to be able to remove the containment suit, though the gloves were always necessary.

The Human Bomb was first published by Quality Comics in the 1940s, and decades later by DC Comics after it acquired Quality's characters. Police Comics #1 also featured the first appearances of Plastic Man and the Phantom Lady, among others.
