Reuben Flagg

History
Born on Mars in 2000 A.D., Reuben Flagg was the lead actor in Mark Thrust: Sexus Ranger. However after the first season, the show's producers replaced him with digital effects. Mark became a member of the Plexus Rangers, the law enforcement of Plex. He proved himself streetwise, tough and morally flexible enough for the job. Flagg discovered Plex's plan to sterilize the US citizens as part of a plan to sell the land via the testament of the late Hilton Krieger. After a series of misadventures, Reuben Flagg became the president of the USA and started social reform. However as soon as he quit and returned to the now-free Illinois, things basically went back to how they were before due to everyone's apathy.
Setting
American Flagg takes place in a future where the America collapsed to by crop failure and nuclear meltdown while the U.S.S.R. was destroyed by Islamic efforts. This led to mass chaos and destruction. U.S. President Silver and the remaining leaders of big industries and banking fled to Mars and created Plex. Plex started as a broadcast company, but a megacorp that effectively took over the world. They use public relation campaigns, drugs and entertainment to maintain control.
