7. He became the Emperor Stark
and ruled the world

In the universe-42777, Tony Stark is still a wealthy genius but also a murderer without scruples. At 14, he killed his father and later secretly financed a war between mutants and humans.
As the mutants were weakened, he betrayed them and publicly made himself a hero. To further advance his rule, he created a famine that he then fought against, and with the fame, he became president. He weakened other countries by artificially triggering natural disasters with a machine. With the help of Dr. Doom, he slowly became the ruler of the world, even though Doom betrayed him and disfigured him.
Ultimately, Emperor Stark
was killed by another variant of Sue Storm (via Marvel Database).
Tony Stark has also done a lot of good in both the comics and the films, but it is noticeable that various authors like to portray him as a ruthless businessman. At least money and power are often a motivation for him. In another universe, Wolverine has his problems too: A new variant of Wolverine is not like the well-known Marvel hero, relentlessly hunting down his own friends
