"The Winning Edge" is the ninth episode of Batman Beyond. It depicts the effects of mass distribution of the drug Venom, now available through an instantly-acting skin patch known as a "slapper". They greatly amplify a person's strength, but are illegal and also highly addictive. Terry discovers that three students in his own school are using these, turning to crime to pay for their habit, and experiencing the negative effects of addiction. Now Batman must stop the manufacture and sale of these drugs before things get too far out of hand.
