Oh and she is also secretly a writer, who rides to wars in disguise. Something like Eowyn of Lord Of The Rings. The one who slayed the Witch King Of Angmar.

Or maybe Mulan. Though i must say i haven't seen that yet. Point is not dragons but that she wants to fight and disguises herself. In those times women were not allowed to fight wars.
I agree about Superman not wishing to leave the world vulnerable. That's why i went ahead and asked the question. What will you do when you win the world? He can do that. There are other options which i am thinking over.
Simply making himself king is not going to work. The empire will crumble in his absence. I made him a thinker, philosopher and a scientist. He would basically popularize the modern ideas and make the world spring to modernity. He nudges the world in this direction. Say some countries will become constitutional monarchies. Renaissance ideas like equality of men, fundamental rights, etc. would be popularized as the government headed by kings would be made more accountable through elected parliaments. This is a boring story for the comics but it can be a fascinating novel.
Superman won't be satisfied with 2000 years. I am not satisfied too. He is then not too different from say founder of an ancient Empire. The problem is that a king of the entire world is even more difficult. It would crumble in one generation. The bigger the empire the more possibility of its failure. Though if you insist on that it's a good story which can be made into a comic book. This is more action packed then my story where Superman basically brings world peace by making all kings his subordinates and then ushers in the modern age.
That's something which requires work. You can't have a good story without conflict. There are two options. Are we setting it in the real world or are we setting it in a world where magic and the supernatural exists? Is Superman the only supernatural being here? Or are there more?
Its important. Because then Amazons won't be existing. They descend from the Greek Gods. Last time i checked Atlantis is a myth. Each setting can bring in a different story. Starting with the setting one can then establish a conflict.
Say for instance if we go with a world with magic you can have a lot of villains who are of magical nature. I can create conflict like this. Science vs Magic. Rational vs Irrational. A small part of the world can be reserved for the villains. Superman had a successful conquest. Most kings agreed to be under him. A few had to be defeated and a favorable monarch established in the respective thrones.
But one region did not bow. It has a lot of magicians and wizards. The battle ended in a standstill. Maybe because the king would rather destroy the kingdom rather then be defeated. Helped by powerful magic he is not easily defeated and can actually kill all people within his kingdom. The people there are kind of blind followers. Not too different from some dictatorships but taken to an extreme level.
In this world magic is a natural talent, irrational and in the hands of the few. Superman focuses on science. Why? Science is but democratization of power. You give power to the people. Instead of depending on some magician to cure a disease medicines cure them. Thus, there is a battle between modernity and tradition. The ideals of equality which science and rational thinking brings versus outdated ideals which are opposite to them as magic supports that. Magic means people are unequal. Some are privileged and others are the common. This theme is the backdrop as those evil villains who mostly are powered by the supernatural fight the idea of the world that Superman envisions.
And of course have those big battles. Luthor may still exist. He is a man of science thus was a friend but did not buy into the ideal of equality. He deserts Superman becomes a sworn enemy and joins the enemy kingdom and helps the magicians even though he is a man of science. Entire DCU can be reworked here. There's one thing i might add. Let Superman not take the crown for himself. He is the most powerful among the Romans but not the king. The administrative work of Rome can be taken up by someone else while he focuses on the larger battle.
Setting it in the real world is more difficult as magic and the supernatural does not apparently exist. Superman has no challenges. You have to reduce his abilities to make an interesting story. Who can even fight Superman in 200 B.C. ?
