Training
Bruce Wayne swore an oath to rid the city of the evil that had taken his parents' lives. He spent his youth traveling the world, training himself to intellectual and physical perfection and learning a variety of crime-fighting skills, including chemistry, criminology, forensics, martial arts, gymnastics, and disguise.
At age 15, Bruce Wayne began his global sojourn, attending courses at Cambridge, the Sorbonne, and other European universities. However, he never stayed long and would often drop out after one semester. Beyond academia, Wayne acquired more "practical" skills.
While abroad, Wayne learned 127 major styles of combat, from Aikido to Yaw-Yan to Ninjitsu. Frenchman
Henri Ducard made him an apprentice in manhunting. The ninja
Kirigi, and other ninja shadow masters, schooled Wayne in stealth and the ways of the shadow warrior. African Bushman (the Ghost Tribes of the Ten-eyed Brotherhood, among others) taught hunting techniques, while Nepalese monks revealed healing arts. He even learned ventriloquism from practioners of the art. His knowledge of so many varied disciplines has made Wayne an unconventional and unpredictable opponent. When he was 20, he attempted to join the FBI, but he learned it would be impossible to fight crime and evil within the legal system.
Peak Physical Condition: Through intense training, specialized diet, and biopathic feedback treatments, The Batman represents the pinnacle of human physical prowess. His physical attributes exceed that of any Olympic level athlete that has ever competed. His strength, speed, stamina, agility, reflexes and coordination are at peak human perfection. Batman began his physical and mental conditioning when he was 11 and then intense physical training and weight lifting at age 12. He has mastered full body control by the time he was 18. Wayne abstains entirely from drinking alcohol, though he presents Bruce Wayne, his alter ego, as a borderline alcoholic (he creates this illusion by drinking ginger ale and pretending it is champagne). Batman's refusal to drink is directly linked to keeping his body in its absolute best physical condition.
