Angered and frustrated when he was forced into early retirement, Hiram Potterstone shifted his incredible skills as an inventor and engineer down a path of crime as a means to stay productive and profitable. His main opponent is Jack-in-the-Box, who, ironically, is also an engineer and inventor.
The Junkman pulled off the greatest heist Astro City ever known. On June 18, 1997, he managed to rob the main AstroBank branch without a trace of the authorities knowing who committed the crime, while making off with almost seven million dollars in cash.
The Junkman's life of crime was spurred on by a forced early retirement in the late 1970s from his company EdgeCo and subsequent dismissals of attempts to find employment at other companies. Even into his 80's he still proved his mind and abilities were still of a use to society. While he's been implicated in over 175 crimes, he's only been caught four or five times and been jailed less than eight months.
Living the high life around at first brought Potterstone, great relaxation, until the fact that the world continued going. No one knew about his spectacular feat of the Great AstroBank robbery yet the world continued to marvel at the deeds and exploits of superheroes, which only enraged Potterstone further and led him back to his life as the Junkman.
Soon after, he stepped back into the spotlight with a partially successful robbery of a bank in Detroit, outfoxing M.P.H. and being stopped from robbing a jewelry store in New Orleans by the Black Rapier. As these open seemingly careless attempts put him back into the spotlight, it soon led many to figure out he was the one behind the original AstroBank robbery.
His undoing came on November 7, 1997 when he attempted to re-rob the AstroBank Tower with the same plan nearly five months later. Jack-in-the-Box was ready for him and with his speed and agility, outmaneuvered the Junkman.
Investigators, were able to find his bases and plans and thought they had everything figured out but why he would come back when he had been away scot-free? With a tape bomb in place in the courtroom and without them finding his money, they never understood it was to "show 'em all."
Tremendously clever in mechanical, electronic and other diverse technologies, he uses his inventions, made from recycled junk, to do pretty much everything.
