In Batman and Psychology: A Dark and Stormy Knight, Travis Langley argues that the concept of archetypes as described by psychologists Carl Jung and Joseph Campbell is present in the Batman mythos, such that the character represents the "shadow archetype". This archetype, according to Langley, represents a person's own dark side; it is not necessarily an evil one, but rather one that is hidden from the outside and concealed from both the world and oneself. Langley argues that Bruce Wayne confronts his own darkness early in life; he chooses to use it to instill fear in wrongdoers, with his bright and dark sides working together to fight evil. Langley uses the Jungian perspective to assert that Batman appeals to our own need to face our "shadow selves". Dr. Travis Langley also taught a class called Batman, a title he was adamant about. "I could have called it something like the Psychology of Nocturnal Vigilantism, but no. I called it Batman," Langley says.
Genius-Level Intellect: Batman's IQ is possibly well over 200; he is a brilliant, virtually peerless, detective, strategist, scientist, tactician, and commander; he is widely regarded as one of the keenest analytical minds on the planet. Given his lack of superpowers, he often uses cunning and planning to outwit his foes, rather than simply "out-fighting" them. Due to his mental training and being naturally gifted, he has acquired an an instant learning aptitude, parallel multitasking, eidetic/photographic memory, accelerated reading, and a more powerful memory. He is the second smartest person on Earth behind Lex Luthor.
In Batman's first appearance in Detective Comics #27, he is already operating as a crime fighter. Batman's origin is first presented in Detective Comics #33 in November 1939, and is later fleshed out in Batman #47. As these comics state, Bruce Wayne is born to Dr. Thomas Wayne and his wife Martha, two very wealthy and charitable Gotham City socialites. Bruce is brought up in Wayne Manor and its wealthy splendor and leads a happy and privileged existence until the age of eigh, when his parents are killed by a small-time criminal named Joe Chill on their way home from the movie theater. Bruce Wayne swears an oath to rid the city of the evil that had taken his parents' lives. He engages in intense intellectual and physical training; however, he realizes that these skills alone would not be enough. "Criminals are a superstitious and cowardly lot", Wayne remarks, "so my disguise must be able to strike terror into their hearts. I must be a creature of the night, black, terrible..." As if responding to his desires, a bat suddenly flies through the window, inspiring Bruce to assume the persona of Batman.
Natalya Trusevich: A Ukrainian concert pianist and girlfriend of Bruce Wayne, Natalya grew frustrated with Bruce's closed-off demeanour, until he was urged by Alfred to reveal to her his secret identity. Shortly after, Natalya was abducted by the Mad Hatter who attempted to torture her into revealing the identity of Batman. Natalya refused to divulge Bruce's secret and was thrown by the Mad Hatter from a helicopter to her death.
