The year is 2120. 100 years ago, a disease broke out that only affected super human kind. The "superheros" -as normal people called them- almost completely wiped out, along with another branch of super human kind, the "supervillains."
Through the years, more and more have started to appear. Their powers vary with the different people. The new superheros have created a large group that helps stop crime all over the world. They are known to the public as "The League of Heros." They are sent out solo, or in teams, to major cities all over the world. The leader of The League of Heros creates and places the teams.
Supervillains are combined into a single group bent on world takeover. They oppose The League of Heros, and will fight against them from time to time. They have many names, but are known to the public as "The Corporation of Evil." They also have a leader, who makes most of the major decisions in the group.
