According to Newsarama.com,
The main character of Max is based upon the real life Jordan Maxwell, a lecturer and documentary filmmaker who is referred to as the Godfather of Secret Societies. Maxwell has led a movement to expose the so-called New World Order and its leaders.
In the comic, this revolutionary movement takes the form of the Third Army who engages in non-violent acts against these bureaucracies which gets them labeled as terrorists. Writer Gustavo Higuera also uses real life characters in his story such as Dr. Roger Leir, a Surgeon and UFO researcher who claims to have removed implants from alien abductees. Higuera throws so much at the reader in the first issue; many characters, different time periods that the story ends up being somewhat fragmented.
Image Comics/Shadowline are the same folks who brought you The Mice Templar and Goatsucker, in case you were wondering.
