SWAT first acted when Scarecrow's base under Arkham Asylum was discovered by Batman. Scarecrow had the police brought over to the asylum and SWAT was called for back up. They were going through the asylum when they were stunned by the swarm of bats used by Batman. Gotham SWAT was called in for security when Ra's al Ghul and his League of Shadows began their assault on Gotham City's Narrows district. Several months later, Gotham SWAT team would accompany the MCU when they entered the Bank of Gotham Building.
