Imagine a world of superheroes. Imagine a world of beings with fantastic powers, who work together to save humanity from the worst super villains imaginable. Imagine a world where the greatest heroes with secret identities come together in an hour of need and formed a near unstoppable team for good. Imagine a world where a wealthy industralist becomes a crime-fighter. Imagine a world where the lone survivor of an extinct alien race becomes a man of steel, dedicating his life to protecting the Earth. Imagine an Amazon princess who was born with superhuman abilities. Imagine a scientist who gained super-speed and superhuman reflexes.
Imagine a world where not everyone who has powers is on the side of good. Imagine a world where insane criminals are given powers, and they individually use their powers to fight the heroes, rarely do they band together. Imagine a world where not every mutant is good, or craves peace and justice. Imagine a world where some with powers are misguided into believing that all of those who do not have super human powers should be crushed under the heels of those who do in the matter of which is the superior race, or simply for their own personal and selfish gains. Imagine a world where sometimes the worst criminals are misunderstood or not misunderstood humans using their sheer intelligence, their profits, and their influence to commit the most terrible crimes.
Imagine a world where magic, science and technology are so powerful when combined, that humans have to be taught how to harness these forces to protect the world from evil of all kinds. Imagine a world where beings are so powerful they could be considered gods. Imagine a world where right next to such forms of magic, many scientific accidents happen that give humans their powers. Imagine a world that has sent humans not only to other galaxies, but also to the past and the future.
This is the world of DC Comics.
