A battle ensues

You start to spread your reach beyond the garden, reaching to the docks and starting to gain attention. And with attention comes superheroes. You see the batwing flying towards your base of operations, and using Batgirl you manage to make him not destroy the garden. He does manage to jump out and land right in front of you, Batgirl, and poison ivy. You send Batgirl to fight him while you figure out how the hell to beat the Batman. But you don't have long because within seconds, he wins. He comes running at you but then out of nowhere, he gets impaled with a vine. You look over at poison ivy and see her standing there, with her hands pointed outwards towards the Batman. You make her pull the vine out, but it's too late. The Batman.... Is dead.
