What comic did Green Lantern first appear in?
Green Lantern first appeared in the comic book "All-American Comics #16" in July 1940.
Created by writer Bill Finger and artist Martin Nodell, the character of Green Lantern has undergone several iterations throughout the years.
The original Green Lantern, Alan Scott, was a railroad engineer who discovered a magical lantern and crafted a ring that allowed him to control the power of the lantern. In 1959, the character was reinvented as Hal Jordan, a test pilot who is chosen by a dying alien to become a member of an intergalactic police force known as the Green Lantern Corps.
Since then, there have been several other characters who have taken on the mantle of Green Lantern, each with their unique powers and abilities.
