Roy Lincoln was a chemist who often collaborated with his father, a demolitions expert, on various experiments. In 1941, Roy's father developed a chemical known as 27-QRX which contained great explosive properties. Nazi agents learned of Lincoln's new chemical and attempted to steal its design so that they could use it as a weapon for themselves, thus giving Nazi Germany an edge over its enemies. The agents raided Professor Lincoln's laboratory and shot him dead. His son Roy, desperate to safeguard his father's work, drank the 27-QRX formula. The result of this rash act yielded bizarre side-effects. Roy Lincoln could cause any item he made physical contact with to explode. With this new power, he was able to defeat the Nazi assassins.
For a time, during WWII, Roy Lincoln served as Head Chemist at the U.S. Navy Laboratory.

- In 1956, DC Comics obtained the rights to the Quality Comics characters, and re-introduced them 17 years later as the Freedom Fighters in Justice League of America #107 (October 1973).
- In 1981, some Quality Characters became recurring guest-stars of All-Star Squadron, a superhero-team title set on "Earth-Two", the locale for DC's WWII-era superheroes, and at a time prior to when the Freedom Fighters were supposed to have left for Earth-X. They later appeared with the rest of DC's superheroes in Crisis on Infinite Earths, a story that was intended to eliminate the confusing histories that DC had attached to its characters by retroactively merging the various parallel worlds into one. The Freedom Fighters became a mere splinter group of the All-Star Squadron.
- This version of the Human Bomb lived in the Quality Universe. He never met nor joined the All-Star Squadron, nor the Freedom Fighters.
