This article is about the fly enemies. For other uses, see Fly (Disambiguation). |
Flies are enemies that buzz around the room randomly. 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.
Contents
Variants[]
Attack Fly[]
Attack Flies are red and black flashing flies that will chase Isaac dealing contact damage.
Attack Flies turn into regular Flies if Isaac has 
Skatole. However, they take a small amount of time to convert into Flies, so it is possible for Isaac to be damaged if the player is not careful.
Notes[]
- The Duke of Flies can spawn larger versions of Attack Flies that have 10 base HP.
- Gurdy can spawn weaker versions of Attack Flies that only have 3 base HP.
Ring Fly[]
Ring Flies are a new addition to Rebirth. They are pink flies that, upon entering the room, will cluster together into a circular formation and orbit rapidly while moving towards Isaac. They will hold formation even as flies are destroyed. The maximum amount of flies per formation is 10.
Notes[]
- Ring Flies are not affected by
Strange Attractor and will continue to stay within their current circular formation.
Moter[]
Moters appear as two conjoined Attack Flies. They behave similarly to regular Attack Flies, but split into two Attack Flies upon being killed. The directions the Attack Flies will split off is parallel to Isaac (vertical if Isaac is to either side, and horizontal if he is above or below).
Notes[]
- If Isaac has Skatole or kills a Moter fast enough, it will not split into two Attack Flies.
Eternal Fly[]
The Eternal Fly is a white-colored fly that can be found on any floor in the game. They usually circle Corn Poop or enemies like Holy Leeches and Hangers, and will not stop circling them until their hosts are destroyed. Before that, they will deal damage to Isaac if he touches them, and they are completely immune to all forms of damage. When their hosts are destroyed, they convert into Attack Flies that can be killed if walked into. Eternal Flies circling Corn Poop do not need to be killed to clear a room.
Notes[]
- Eternal Flies can be killed by Chaos Card, Little Horn, and Euthanasia.
- Their bestiary entry states that they have 300 HP.
Dart Fly[]
Dart Flies are similar to regular Attack Flies, but attempt to predict Isaac's movements and cut him off.
Swarm Fly[]
Swarm Flies are similar to regular Attack Flies, but appear in tightly-packed clusters.
Notes[]
- If a Swarm Fly is somehow separated from its group, it quickly moves back to its group when it is able to.
Hush Fly[]
Hush Flies are mainly spawned by Hush and behave somewhat similar to Ring Flies, flying towards Isaac in certain patterns. Unlike Ring Flies, Hush Flies can form other shapes such as polygons and can also orbit Hush.
Hush Flies have a brief period of invincibility when Hush spawns them, making them appear to have more health than they actually have.
Hush Flies are not affected by the Beelzebub transformation.
Hush Flies can also spawn outside of the Hush fight in some rare rooms.
Army Fly[]
Army Flies chase Isaac, moving in the cardinal directions as they do so. If there are other Army Flies in the room, they will form a single-file line while chasing Isaac.
Willo[]
Willos circle a set distance around Isaac, moving with him perfectly, and firing shots inwards towards him; only one can fire at a time, and the one about to fire telegraphs this by flashing rapidly just beforehand. They circle quickly, and can be hard to hit. If there is a Fire Place within the room, they can be guided into it; making this an efficient method of tackling this enemy.
Notes[]
- Min-Min can spawn these; some of them behave normally, while some pop out of the ground, launch a volley of shots at Isaac, and disappear back into the ground.
- Mullighouls spawn these occasionally, and spawn 2 more when they die.
Ultra Famine Fly[]
Ultra Famine Flies are flies spawned by Ultra Famine that charge at Isaac on a delay. They come in 3 sizes- small, medium and large.
Ultra Pestilence Fly[]
Ultra Pestilence Flies are flies spawned by Ultra Pestilence that swarm around him, blocking shots and dealing contact damage. They also can be spawned by the Ultra Pestilence Fly Ball in Ultra Pestilence's 2nd phase. They come in 3 sizes- small, medium and large.

Trivia[]
- The Black Fly has the lowest health of any enemy in the game, tied with the Corn and Drip.
- Eternal Flies were first added to the Wrath of the Lamb DLC for the original Binding of Isaac game.
- 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]
