The Patriot

Jack Simmons gained superhuman abilities by ingesting a unique serum that activated a latent genetic potential within him. He adopted the name and the red, white, and blue garb of the Patriot, becoming a member of the Liberty League during World War II. After the war, the Patriot continued to work for the United States government as a special agent and troubleshooter long after the dissolution of the League. He hung up the Patriot uniform and became the first director of AEGIS after being instrumental in its organization and planning.
Although his powers lengthened his life and gave him greater than normal vitality, the years eventually caught up with Simmons and he chose to retire, passing the directorship of AEGIS to Harry Powers, his most trusted agent.
A few years ago, Jack learned he suffered from inoperable cancer, possibly from fighting nuclear-powered villains over the years or as a side effect of the Patriot Serum. Secluded in a government hospital as his condition deteriorated, Jack received a last-chance offer from some friends of his. They could help him, and he could help America. He agreed, and not long thereafter, Jack Simmons quietly passed away.
What the world doesn’t know is the U.S. government used engram-recording technology pioneered by Dr. Atom to download Jack Simmons’ mind into an advanced android resembling Jack in his younger days. His new android body gives the Patriot greater abilities than ever before, and he continues to work as a secret weapon in America’s arsenal against terrorists, super-criminals, and other threats.
Thus far, AEGIS is quite pleased with the effectiveness of the neural transfer: all the Patriot’s knowledge and experience in a superhumanly capable, ageless, tireless physical form. Director Powers is considering a proposal to arrange a cover origin for Agent Irons, so a “new” Patriot can join the Freedom League as a way of keeping an eye on them. The only details to work out are just how much to reveal about the new Patriot’s physical status; concealing his android nature from the League members could be problematic, but hiding that he’s really Jack Simmons shouldn’t be all that difficult. An alternate possibility is for the Patriot to become leader of a new team of AEGIS super-agents.
For his part, Simmons has acclimated to his new existence and continues to serve his country and the agency he founded. He occasionally runs into trouble with his old “take charge” reflexes, realizes he’s not in charge any more, and allows Harry Powers to do his job, since Jack considers him “a good kid”.
