The name of several comic book characters published by DC Comics. The original Green Lantern, Alan Scott was created by Martin Nodell and first appeared in "All American Comics" #16 in 1940. In 1959 the concept of the Green Lantern was reimagined with the character of Hal Jordan who debuted in "Showcase" #22. Several human Green Lanterns including John Stewart, Guy Gardner, and Kyle Rayner have followed the tradition of Hal Jordan as well as thousands of alien Green Lanterns across the universe.

The Green Lanterns all share the basic concept of possessing a Power Ring which can create virtually anything the wearer wishes, limited only by the wearer's willpower and imagination. The Power Ring carries a finite charge and must periodically be recharged from a Power Battery in the form of a green lantern.

Gah... idiots...

Anyway... Green Lantern... a comic book character created in 1940 by Sheldon Moldoff (I believe) for All American Comics.

There have been three major Green Lanterns... the Golden Age GL, Alan Scott, the Silver Age GL, Hal Jordan, and the current Green Lantern, Kyle Rayner.

Green Lantern is still published monthly by DC Comics (who acquired All American in the 40s) and can be found at your local comic shop or bookstore.
