Batman writer/editor Denny O'Neil created Venom is his Legends of the Dark Knight story also titled "Venom". The series depicts Batman becoming hooked on the substance as it greatly improves his abilities and strength but begins to become dependent. Only after locking himself in the Batcave for a prolonged period of time is Bruce able to overcome his addiction.
The substance was later used in the creation of the villain Bane in a new super-soldier form.
Venom is the name of an addictive super-steroid, most commonly used by Bane, who has a network of tubes which pump the substance throughout his body.
The drug that would become known as Venom was originally created by designer drug specialist Dr. Randolph Porter. It was originally invented in pill form and was to be used to help create an army of mercenary mind-controlled super soldiers. When Porter fled Gotham city to escape justice at the hands of Batman, he ended up in Santa Prisca. There Porter perfected the Venom formula and created an injectable form of the drug. This is the version that would later be used by Santa Prisca native Bane , the man who broke Batman's back.
The history of the Venom drug was later changed in the pages of JSA Classified number 17. There it was revealed to be an enhanced version of the Miraclo formula, the pill created and used by JSA member The Hourman.
Bane uses Venom in almost all his Other Media incarnations to pump himself up to a great size and take on the Batman. Some more notable examples of Venom are;
