Batman is one of the most popular heroes of DC Comics Universe. First time he was mentioned in Detective Comics No27 in May, 1939. He has no special powers or abilities. His true name is Bruce Wayne and he's a billionaire. He's a very clever and well-educated man. So, all his "powers" are created by himself. As usual, he overcomes his enemies with stratagem and his self-created weapons. Also he is famous with his Batmobile. It's a great car with incredible abilities. It's also made by himself. He's also known as Dark Knight. Gotham is the city, protected by Batman. Joker is his most famous enemy.
I think he's one of the greatest heroes in all comics Universe.
