The biggest villain organization in the universe lives in Jump City: the Teen Titans.
They’ve destroyed Apokolips and Krypton, destroyed Earth several times, and made the sun disappear because they hated the sunlight. They’re civilization-ending forces that even the Starro invaders can’t hold a candle to.
They blast innocent civilians’ cars because of a traffic jam, and run over the cars beside them to get a parking spot.
They punch Darkseid and kick the people of Arkham.
