The Mad Pharoah!
With the help of Iron Man, an archaeological team unearths the tomb of King Hatap, "The Mad Pharoh", Egyptian sorcerer and rival to Cleopatra.
Except Hatap isn't dead!
Turns out he's been in suspended animation, awaiting the chance to return to the past and assail Cleopatra's forces once more. The revived Hatap, recognizing Tony's scientific brillance, takes him back to the past with in the hopes of utilizing his skills.
Tony escapes Hatap and dons the golden armor just in time to land himself smack dab in the middle of a Roman invasion -- and harboring a mighty crush on the beautiful Cleopatra.
Iron Man then manages to stop the attacking Roman forces. Hatap tries to go back to the future, but Iron Man squirts oil at the bracelet which took them to the past, making it fall out of Hatap's hands. Hatap lunges to grab it, but falls on an upturned sword, killing him.
In the present, archaeologists look at hieroglyphs, and try to work out why there would be a hieroglyph which appears to be Cleopatra embracing a figure who looks like Iron Man.
