Flies buzz around the room randomly, often moving away from the player. 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 or come in contact with a golden poop.

Attack Flies are red and black flashing flies that will follow Isaac relentlessly until killed. Their only way of damaging Isaac is by contact, and they move rather slowly, making them easy to kill. However, they can be dangerous when found in groups, as they can swarm around Isaac quickly.

Attack Flies turn into regular Black Flies if Isaac has Skatole SkatoleSkatole Icon.pngAll types of fly except Boom Fly and Red Boom Fly become passive and slowly move towards Isaac. Does not prevent contact damage.. They take a small amount of time to convert into Black Flies, so it is possible for Isaac to be damaged if the player is not careful.

Notes[edit | edit source]

  • The Duke of Flies and other bosses can spawn larger versions of these flies which have 10 Base HP.

Dart Flies are similar to regular attack flies, but attempt to mimic Isaac's movements. Their only way of damaging Isaac is by contact, and they can move fairly quickly, making them potentially dangerous when found in groups.

Swarm Flies are similar to regular attack flies but appear in tightly-packed clusters. Their only way of damaging Isaac is by contact, and although they move fairly slowly, they can be dangerous by simply outnumbering Isaac.

Notes[edit | edit source]

  • If a Swarm Fly is separated from its group due to being petrified, it quickly moves back to its group once unpetrified.

Hush Flies are spawned by Hush and behave somewhat similarly to Ring Flies, flying as towards Isaac in certain patterns. Unlike Ring Flies, they 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 have.

Hush Flies are not affected by the Beelzebub Transformation.

Added in Afterbirth † Hush Flies can also rarely spawn outside of the Hush fight in rooms.

Moters appear as two Attack Flies joined together. They behave similarly to regular Attack Flies but split into two Attack Flies upon being killed. Their split is very wide and unpredictable and can easily shave off half a heart. It is recommended to kill faster flies and other small monsters before it as the two flies it spawns are more dangerous in many ways. Running between them just as they split is also a very good way to dodge.

  • If Isaac has Skatole SkatoleSkatole Icon.pngAll types of fly except Boom Fly and Red Boom Fly become passive and slowly move towards Isaac. Does not prevent contact damage., or uses a bomb, killing a Moter will not make them split into two Attack Flies.

The Eternal Fly is a white-colored fly that can be found on any floor in the game. They usually circle corny poop or enemies like Holy Leeches and the Hanger 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're completely immune to all forms of damage. When their hosts are destroyed, they convert into Attack Flies.

  • If Eternal Flies are circling Corny Poop and there are no other enemies around, you can leave the room at will. This is true even if they have already been converted into large attack flies: they will simply disappear when you return into the room.

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 when you destroy all but one fly. The maximum amount of flies per formation is 10. These flies are fast and take up a large amount of space, so it may be recommended to hold these on higher danger priority.

The Sucker has a greater amount of health than a regular fly and slowly moves towards Isaac. Upon death, it shoots 4 bullets in all cardinal directions. Suckers are unaffected by Skatole SkatoleSkatole Icon.pngAll types of fly except Boom Fly and Red Boom Fly become passive and slowly move towards Isaac. Does not prevent contact damage., so they're always hostile.

Despite their simplistic behavior, Suckers can prove rather dangerous at late levels. This is because oftentimes they'll be positioned in areas containing hazards or the player may have familiars that attack the Suckers regardless of the player's intention. As a result, the low health that the Suckers possess can be used to give the player little time to react when they die quickly and shoot their projectiles outwards.

The Spit looks like a green version of the Sucker, and it shoots one explosive green bullet at the player upon death. The shot behaves exactly like Ipecac IpecacCollectible Ipecac icon.pngReplaces tears with explosive and poisoning projectiles fired in an arc from the mouth.. Spits are unaffected by Skatole SkatoleSkatole Icon.pngAll types of fly except Boom Fly and Red Boom Fly become passive and slowly move towards Isaac.

Soul Suckers were added in Booster Pack #4.

The Soul Sucker looks like a bloated, red-spotted version of the Sucker. Upon death, a swirling red vortex appears where it died, which then fires four Brimstone BrimstoneCollectible Brimstone Rebirth icon.pngTears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period. beams in the four cardinal directions after a short delay.

The appearance of the vortex resembles the same vortex that is spawned whenever the player fires with Brimstone BrimstoneCollectible Brimstone Rebirth icon.pngTears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period. and Anti-Gravity Anti-GravityCollectible Anti-Gravity icon.png-2 Tear Delay. Tears float in position until firing ceases, after which they will fly off in the direction they were shot in..

Notes[edit | edit source]

  • The Brimstone lasers from the Soul Suckers can damage other enemies, including other Soul Suckers. You should play carefully when facing multiple Soul Suckers, as their vortex attacks could corner you if you're not careful.

Trivia[edit | edit source]

  • The Black Fly has the lowest health of any enemy in the game, tied with the Added in Afterbirth Corn.
  • There is a fly enemy in the Eternal Edition of the original Binding of Isaac that is a ball of 4 attack flies, resembling 2 Moters stuck to each other. This enemy does not appear in Rebirth.
  • Suckers seem to be based on mosquitoes, midge-like flies that suck the blood of other animals, as they seem to share a small proboscis and blood sac.
