Michael Lawrence "Mike" Fleisher (born November 1, 1942) is an American writer known for his DC Comics of the 1970s and 1980s, particularly for the characters the Spectre and Jonah Hex.
Doctor Fate (also known as Fate) is a fictional superhero appearing in American comic books published by DC Comics.
 The character has appeared in various incarnations, with Doctor Fate being the name of several different individuals in the DC Universe who are a succession of sorcerers.
 The original version of the character was created by writer Gardner Fox and artist Howard Sherman, and first appeared in "More Fun Comics" #55 (May 1940).
Green Arrow is a fictional superhero who appears in comic books published by DC Comics.
 Created by Mortimer Weisinger and designed by George Papp, he first appeared in "More Fun Comics" #73 in November 1941.
 His real name is Oliver "Ollie" Queen, a billionaire businessman and owner of Queen Industries who is also a well-known celebrity in Star City.
 Sometimes shown dressed like 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.
 Though much less frequently used in modern stories, he also 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.
 At the time of his debut, Green Arrow functioned in many ways as an archery-themed analogue of the very popular Batman character, but writers at DC subsequently developed him into a voice of left-wing politics very much distinct in character from Batman.
The Spectre is the name given to several fictional superhero characters who have appeared in numerous comic books published by DC Comics.
