The newest incarnation of the Green Lantern re-images the Green Lantern as an Arab-American Muslim from Dearborn. Simon Baz takes the mantle of the Green Lantern after the death of the last Green Lantern. The new version of the Green Lantern was launched on the anniversary of 9/11 and is also supposed to illustrate that Muslim-Americans suffered as much from the unfortunate events of 9/11 as the rest of the nation. While there has been Muslim superheros in mainstream comics in the past, Simon Baz is the first Muslim superhero for a major well known franchise. Wikipedia has a much more detailed fictional biography of Simon Baz.
