Young Justice Season 1 Episode 4 : Drop Zone
Kobra has taken over the operations in Santa Prisca where Kobra's minion Mammoth ends up defeating Bane.
Despite lacking a clear leader, the gang is assigned its first mission by Batman. They later get caught in the middle of a war between Bane's gang and the Cult of the Kobra (who are assisted by Cadmus' operative Sportsmaster) over the production of the drug Venom.[4] Aqualad agrees to be the leader until Robin is ready to take over.
Batman congratulates the team on a successful mission despite a rocky start. Meanwhile, Sportsmaster gives The Light the remaining vial of the Venom/Blockbuster Formula combination.
