Green Lantern was first created in 1940 by Bill Finger and Martin Nodell and even though the concept was radically changed in the late 50s, the comic has grown increasingly popular in the decades that followed, arguably hitting its peak within the past few years, thanks to Geoff Johns and his own expansion of the mythology/universe. Johns' first course of action was to bring back the Silver Age Green Lantern, Hal Jordan, the standard for all Corps members to follow. Post-rebirth, Johns kicked off what may be one of the biggest and deepest expansions of any comic book in history - from the introduction of new Lantern Corps' (each relating to a color of the spectrum and assigning an emotion to each) to the hugely successful "Blackest Night," "Green Lantern" (and its family of Lantern books) have either introduced or claimed characters from DC's storied history and made them their own. This list is an attempt to round-up the greatest, most relevant heroes and villains to grace the pages of Green Lantern...
10. Abin Sur
Abin Sur's greatest tragedy is that he must die. If he had survived the crash of his ship, Hal Jordan would never have become a Green Lantern and things would have turned out quite differently. As such, he may not be the most important but he is the most crucial. We never truly get to know Abin through his actions, but rather through the words of others:who he was, what he meant to the Corps and what he passed down to his student (and brother-in-law) Thall Sinestro. We learn that he knew of the "Blackest Night" prophecy, his secret creation of the Indigo Tribe (emotion: compassion) and his plan to fight the Guardians of the Universe. Abin's story is one of legend, a story passed down by other characters and the shame is we never got to see it properly.
