Batman Arkham Knight: Most Wanted, Creature of the Night

The Creature of the Night is a side quest, and part of Gotham's Most Wanted in Batman: Arkham Knight. In this mission you must track down the Man-Bat. The starting point can be found after first arriving in Miagani Island in the Main Story, where you will run into him after grappling off the top of a building. After this point you can spot Manbat flying through the skies, and your cowl will pick up his screeches.
