Robert Benton (New Earth-Twenty One)

Origin
Robert Benton was a pharmacist from Chicago attempting to create a tonic that could help people. His assistant, Tim Ronald would accidentally add formic acid to the tonic, which angered Robert at first. Robert would accidentally inhale some of the resulting mixture and would cause his eyes to glow, much to his and Tim's shock. The two would discover that the mixture also granted Robert super strength, durability, reflexes, senses and healing.

Robert would quickly decide to use his powers to become a superhero like he always wanted to. He would be joined by Tim who would also take some of the mixture in order to aid him in crime fighting. Robert would go on to take the alias, Black Terror and Tim would take the alias of Kid Terror and the duo would become known as the Terror Twins.

Heroic Career
The duo would fight crime together for two years, becoming well known in Chicago. They would fight a wide variety of different groups from common criminals, Communist Spies, Nazi war criminals, and even demons.

Death of Kid Terror
The duos partnership and careers in crime-fighting would end tragically after Kid Terror sacrificing himself to save Chicago from a nerve gas bomb created by a mad scientist. Black Terror would kill the scientist and would retire from heroics afterwards viewing himself as unworthy to continue being a superhero.
