Little is known about the past of the Pharaoh Hatap, but because of his knowledge of the black arts and his ruthless crimes, he earned the title Mad Pharaoh. Approximately 2000 years ago, he had staged a rebellion against Cleopatra. When the tide of the battle turned against him, he took a potion that put him in a state of suspended animation for 2000 years. Believing him to be dead, Cleopatra had him embalmed and entombed as befit a man of his stature, according to his final will and instructions.
In the modern era, Tony Stark, both as himself, and as Iron Man, assisted his old friend Paul, an archaeologist, in the excavation of Hatap's Tomb. Hatap then revived and cast a spell afflicting the others working on the excavation with a disease which would spread across the earth, unless Stark agreed to return with Hatap to his era, defeat Cleopatra, and rule Egypt, as he had originally planned. Hatap used his magic charm to summon his "Chariot of Time" and bring the two back to ancient Egypt.
After arriving in the past, Stark broke away from Hatap, changed into his Iron Man armor, and escaped. Iron Man made his way to the court of Cleopatra and helped defend it against an attack by a Roman legion. Earning the gratitude and friendship of Cleopatra, Iron Man informed her of Hatap's plans and helped her fight off his army. Fearing defeat at Iron Man's hands, Hatap sought to use the charm to return to the modern era, but Iron Man squirted some oil on the charm, causing Hatap to drop it. Diving for the charm, Hatap inadvertently landed on an upturned sword, which apparently killed him. Hatap's army fled, and Iron Man used the charm to return to his time, despite Cleopatra's requests that he stay and rule by her side.
