When the National Bank noticed the rise of costumed adventurers, the company's marketing team decided it would be a very interesting publicity prospect to be able to brag that a self-owned superhero would be protecting their customer's money. Fashion designers were employed by the bank to make a costume. For aesthetic purposes and to raise maximum publicity appeal, the costume was extremely gaudy, with a large dollar sign on the front and a cloak that draped to the floor, especially liked by the test audiences.
William Brady decided to answer an ad for the National Bank. He was the 14th who saw Misters Abie, Howe, Cheatem, and Dewey that day, and the only one who agreed to don the gaudy costume (although he had reservations about the cape restricting his movement) and work for the National Bank as the mascot superhero known as Dollar Bill.
The employees at National Bank convinced Brady to tryout for the Minutemen, despite having zero crime-fighting experience, to raise the bank's publicity. Captain Metropolis and Silk Spectre gladly accepted Brady in the team, as they realized that Dollar Bill's presence would be an asset to their public profile.
National Bank would become a sponsor for the Minutemen Franchise LLC, as the Minutemen would promote the bank after giving a press conference.
A branch of the National Bank was robbed by a gang of thieves and held hostages. The bank was surrounded by the police, but the Minutemen were there to defeat the criminals.
During World War II, Dollar Bill had a fancy deferment by the bureaucrats and was not enlisted. He continued to work as a mascot of the National Bank and appeared whenever a new branch was opened, usually with Mothman as a surprise guest.
In 1947, while attempting to stop a raid upon one of the branches of the National Bank, Dollar's Bill cape became entangled in the bank's revolving door and he was shot at point-blank range before he could free it.
