The Black Fly is an enemy in The Binding of Isaac: Rebirth that is very commonly encountered on every floor in the game. It is a large black fly.


The Black Fly slowly flies around the room, gathering around Poop and ignoring the player, unless the player has Skatole, in which Black Flies will gather around the player. It deals no damage to the player whatsoever. The Black Fly can fly over Rocks, Spikes, Holes, and other obstacles. The Black Fly, if flying around Poop for a while, may turn into a Pooter. Black Flies can sometimes be time consuming to kill, for they can fly over rocks and remain stationary for a moment, not allowing the player to shoot them. It is spawned by many enemies, some examples being:

  • The Duke of Flies
  • Hive
  • Mulligan
  • Swarmer
