Green Arrow is a superhero who appears in American comic books published by DC Comics. Created by Mort Weisinger and designed by George Papp, he first appeared in More Fun Comics No. 73 on September 19, 1941, the same issue that debuted Aquaman. His real name is Oliver Jonas Queen, a wealthy businessman, owner of Queen Industries, and a well-known celebrity in Star City. He uses this position to hide the fact that he is Green Arrow. Partly inspired by Robin Hood, Green Arrow is an archer who uses his skills to fight crime in his home cities of Star City and Seattle, as well as alongside his fellow superheroes as a member of the Justice League. The world's greatest archer, as well as a competent swordsman and martial artist, Green Arrow deploys a range of trick arrows with various special functions, such as glue, explosive-tipped, grappling hook, flash grenade, tear gas, and even kryptonite arrows for use in a range of special situations.
