Fly

This article is about the fly enemies. For other uses, see Fly (Disambiguation). Flies are enemies that buzz around the room randomly, but slowly hover towards Isaac. They cannot damage Isaac at all, even by touch, making them completely harmless. However, they can turn into Pooters if they fly around Poop for too long. Along with monsters like the Gapers and Spiders, Flies are one of the most commonly-encountered monsters and appear in numerous different types.

• The Black Fly has the lowest health of any enemy in the game, tied with the Corn.
• Eternal Flies were first added to the Wrath of the Lamb DLC for the original Binding of Isaac game.
• Before Rebirth, Eternal Flies simply became vulnerable and chased the player rather than turning into an Attack Fly.
• There is a variant of Moters in the Eternal Edition of the original The Binding of Isaac that resembles a ball of 4 Attack Flies, or 2 Moters stuck to each other. This enemy does not appear in Rebirth, likely due to being added in said Eternal Edition update that was added a while after the release of Rebirth.
• In a Q&A Reddit thread by Edmund McMillen, Edmund confirmed that the species of flies in The Binding of Isaac are house flies and botflies.[1]
