Handolf Zwinkler is a 62 year old German native but moved to Chernarus in his early 40's when he met his Chernaran wife. Handolf was an eccentric child. In high school he never fit in with any groups and found himself alone with his thoughts. His thoughts were tormented by ideas of pain and torture, leading him to be obsessed with anatomy and biology. Dissections fascinated him and his father was constantly pressuring him to become a doctor. After graduating high school, Handolf began running experiments on himself, often using drugs like Methamphetamine and Bath Salts not to feel the high, but to feel the come-down. His isolated lifestyle lead him down a dark path that resulted in his love for pain. Some of these self-inflicted wounds came from burning, belt sanding himself, electrical shocking, and back waxing. In this dark time he met his wife, Dinkla Zwinkler, who was his first patient as a doctor. They moved back to her homeland, Chernarus, together where Handolf conducted strange experiments on his wife that resulted in her death. Her death resulted in his imprisonment for medical malpractice and operating without a medical license. During his time in prison he continued his twisted experiments on the prisoners. When the apocalypse broke out Handolf still behind bars. Lenny Hauler and Nedrick Divini, looking for a place to stay, happened upon the prison and found Handolf in his cell. Lenny, recognizing Handolf immediately went to work bending the bars with his immense strength to free Handolf from his prison. Ever since Handolf has been a part of their group, but secretly has been running experiments on Lenny, attempting to find an enhancement for himself, which will give him the strength and power of Lenny Hauler.
