This reality presumably shared a similar history to the Prime Marvel Universe counterpart until the death of Kang during the "Great War". Tony Stark worked with Cybermancer worked together using Kang's blueprints. The sky turned black, the air became unbreathable, artificial intelligences gained flesh bodies and flesh bodied humans had parts of themselves enhanced cybernetically. At some point he recruited Wonder Man to operate as his killer. About 10 years after this, Cybermancer found herself on the Prime Marvel Universe and worked briefly for their Tony Stark. After this their reality began to collapse. Stark's fate is unknown but was presumably killed when the entire reality was destroyed.
