Bane in the DC Comics series is the only super-villain to have broken Batman's back in a fight. Bane became a test subject for a mysterious drug known as "Venom," which had killed the other test subjects and he was the only one who survived. Bane found the drug caused him to have superhuman strength, although he needed to take it via a system of cables pumped directly into his muscles. In the comics, the drug Venom was a mixture of radioactive steroids, growth hormone and Amino Acids for muscle growth. Although radioactive steroids may be science fiction, the anabolic effects of amino acid are not.
