Changes

By November of that year, Batman's origin story - the murder of his parents - was set; this storyline of a boy growing up to avenge his parents struck a chord with readers, and sales of the comics grew.  The following year he appeared in his own series under the "Batman" name - published alongside ''Detective Comics'' - which also introduced "Robin, the Boy Wonder", a successful attempt to gain younger readers as well as creating the popularity of the "sidekick" in the comics industry; Green Arrow and Speedy, the Human Torch and Toro, and [[Captain America]] and Bucky would be prime examples of this trend.

The combination of Bob Kane and Bill Finger (Finger was largely uncredited after Batman's creation) in the early-1940's also introduced to the comics world several of the most recognizable villians in fiction.  Created were "Two-Face", a scarred villian reportedly based upon [[Robert Louis Stevenson]]'s ''[[Dr. Jekyll and Mr. Hyde]]''; the "Cat", a sensuous woman who became better known as "Catwoman"; and the "[[Joker]]" - which Kane based upon the image he saw of actor Conrad Veidt in the silent film ''The Man Who Laughs'' - a nightmarish version of a clown who is the antithesis of everything Batman is, and who became one of the best known villians in fiction.
