Despite imprisonment, Bane developed exceptional intellectual and physical discipline. He read extensively, trained constantly, and created personal methods of meditation to manage pain and isolation. He learned to fight within the prison’s violent hierarchy and committed his first murder at eight.
Cultural exposure within Santa Prisca and among prisoners allowed him to learn English, Spanish, Portuguese, Persian, Urdu, and Latin. He also received a classical education from an elderly Jesuit priest held at Peña Duro.
His only companion was Osito, a teddy bear used to conceal a small knife. Throughout childhood, Bane experienced recurring nightmares involving a giant bat, forming the basis of his later fixation on Batman.
Bane eventually became the dominant figure within Peña Duro’s inmate population.
