The Omega War
The United Tribes World
This world is very similar to the home world of the protagonists. It differs largely in that the American continent is occupied by the United Tribes of America, a nation formed by the Natives in cooperation with English colonists. The United Tribes are a democracy, governed by President John Running Bear.
This world had a team of Omegas called the Defenders, but they are now deceased.
England in this world is governed by Queen Diana, and seems to be more of a police state with Omegas quelling riots and rebellions.
South America is a fractured continent dominated by the Aztecs, but with many small countries made up of Mayans, Olmecs, Toltecs and so forth.
