Newuniversal
In the alternate world of newuniversal, Tony Stark is one of three humans altered by the Fireworks on April 26, 1953, gaining abilities associated with the Cipher glyph. Prior to the Fireworks, Stark is unexceptional, but he then becomes a technological genius. His discoveries revitalise his father's company, Stark Industries, and are "five years ahead of everything everyone else is working on". There are suggestions that he is capable of more, but is not making all of his discoveries public.
Stark's transformation is noticed by the National Security Agency's Project Spitfire, which is discreetly monitoring the superhumans created by the Fireworks. In March 1959, Stark's plane crashes in North Vietnam and he is imprisoned. He escapes by constructing an Iron Man suit from "spare parts" and flying out of the country.
On April 4, 1959, when he returns to the USA, the NSA takes Stark to a San Diego naval base, ostensibly to debrief him. Stark is then shot dead by Philip L. Voight, a Project Spitfire agent, to prevent him from making contact with the other superhumans.
The Iron Man suit is seized by Project Spitfire and reverse engineered by Doctor Joe Swann, eventually becoming the basis of the project's H.E.X suit, an exoskeleton designed for combat with superhumans.
