Venom

Venom is a potently addictive strength-enhancing super-steroid. According to JSA Classified #17 (November 2006), Venom is based on the Miraclo formula developed at Bannerman Pharmaceuticals, the drug company formerly owned by Rex Tyler, the original Hourman. The first appearance of the drug was a five-part story arc, Batman: Venom, in Legends of the Dark Knight issues 16-20. Batman became addicted to the drug while searching for a way to cope for his imperfections. Later, it resurfaced as the power source for Bane, who used it to overpower and cripple Batman in the Knightfall story arc. A version of it is used by President Lex Luthor in the first "Superman/Batman" story arc.

In the Batman Beyond universe, steroid patches known as "Slappers" contained small doses of impact-release Venom. They were mainly used as performance enhancers in competitive sports, although the use of multiple patches could produce Bane-like combat abilities.

In the Batman & Robin, Venom is engineered by Pamela Isley (Poison Ivy) to be injected into plants for the power to defend themselves like animals. Her coworker Dr. Woodrue steals samples of Venom to create a super soldier army of which Bane is the prototype. Venom is also part of Isley's transformation into Poison Ivy.
