In the last decade, two more human Green Lanterns joined the roster. Simon Baz debuted in 2012, first in a Free Comic Book Day special, and then in Green Lantern #0. Created by Geoff Johns and artist Doug Mahnke, Baz is a Lebanese-American Muslim from Dearborn, Michigan. A former car thief wrongly arrested for terrorism, becoming a Green Lantern gives him a chance to prove what heroism he's capable of.
The next year, in Justice League #30, another new Green Lantern was introduced. Jessica Cruz is first targeted by an evil power ring from an alternate Earth, but upon overcoming its power, she is given a proper Green Lantern ring. A Latina woman who deals with anxiety and PTSD, Jessica has opened the door to new kinds of stories about heroism and courage. Simon Baz and Jessica Cruz frequently work as partners, and even join the Justice League in tandem, in addition to starring in their own Green Lanterns (note the plural) comic.
All told, there are six prominent Green Lanterns of Earth in DC Comics (not counting Alan Scott), all of whom have been in the Justice League. Surely, given enough time, energy, and talent, Warner Bros. can figure out how to make a good movie out of at least one of them, right? Fingers crossed.
