Superman

Superman is the most powerful being on planet Earth, an alien immigrant named Kal-El from the planet Krypton who was raised in Smallville, Kansas, to become an American superhero. Raised with high moral ideals, he uses his incredible strength, speed, flight and various other superpowers to fight evil and protect the innocent. In his civilian identity he is Clark Kent, a mild-mannered reporter working for the Daily Planet in Metropolis. He is a founding member of the Justice League of America and a charter member of the Legion of Super-Heroes in the 30th Century.

My opinion - I think Superman is the most popular character in DC Comic. Everyone knows Superman and his ability such as his eyes can release laser, he can fly ,stronger than normal human, etc.
