Flies are very common enemies, found on almost every floor. They can also be spawned by various monsters and bosses, including Duke of Flies, The Husk, Hives, Swarmers, Gurdy, and Pestilence. Skatole changes the behavior of all types of flies. The Lord of The Flies transformation converts some types of flies into Blue Flies.

Black Fly[edit | edit source]
Black 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 Fly[edit | edit source]
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. 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.
Large Attack Fly[edit | edit source]
These have the exact same behavior as regular attack flies, and move at the same speed. However, they are larger and have more health than regular Attack Flies.
Dart Fly[edit | edit source]
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 Fly[edit | edit source]
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.
Hush Fly[edit | edit source]
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 actually have.
Hush Flies are not affected by the Beelzebub Transformation.
Hush Flies can also rarely spawn outside of the Hush fight in rooms.
Moter[edit | edit source]
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 actually more dangerous in many ways. Running between them just as they split is also a very good way to dodge.
- If Isaac has Skatole, or uses a bomb, killing a Moter will not make them split into two Attack Flies.
Eternal Fly[edit | edit source]
The Eternal Fly is a white 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 are 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.
Notes[edit | edit source]
Ring Fly[edit | edit source]
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.
- Ring Flies are not affected by Strange Attractor and will continue to stay within their current circular formation.
Boom Fly[edit | edit source]
Boom Flies roam around the room diagonally, dealing touch damage and exploding with a large blast radius upon death. Skatole slows them down, but they remain dangerous. They also spawn from blue champion bosses such as Fistula.
Red Boom Fly[edit | edit source]
Flies around the room diagonally, dealing touch damage and exploding into 6 directional blood shots upon death. Skatole will only slow down their movement.
Drowned Boom Fly[edit | edit source]
Drowned Boom Flies fly around the room diagonally, dealing contact damage. Upon death, they explode, release 4 blood shots in the cardinal directions, and spawn a Drowned Charger. Occasionally the Drowned Charger will not spawn, and only blood shots will be fired.
If a Drowned Boom Fly dies while over an obstacle or pit, the Drowned Charger will not be spawned.
Level 2 Fly[edit | edit source]
The Level 2 Fly flies towards Isaac somewhat erratically, dealing contact damage.
Full Fly[edit | edit source]
The Full Fly behaves similarly to the Level 2 Fly and Red Boom Fly combined, it chases Isaac and shoots 6 blood shots upon death. Full Flies do not run into Isaac, but will actually orbit around him closely until he moves, which may end up causing him to run into the fly.
Pooter[edit | edit source]
The Pooter very slowly wanders around the room to the point where they basically stay put. They shoot one bullet at Isaac. Pooters will not shoot if Isaac wears Skatole.
Super Pooter[edit | edit source]
The Super Pooter behaves like the Pooter, except it shoots two bullets in a V-shaped pattern. Also does not shoot Isaac with Skatole.
Trivia[edit | edit source]
- Prior to Afterbirth †, Super Pooters were called Fat Flies.
Sucker[edit | edit source]
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, so they're always hostile.
Despite their simplistic behaviour, Suckers can actually prove rather dangerous in late levels. This is because often times 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.
Spit[edit | edit source]
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. Spits are unaffected by Skatole, so they're always hostile. Like most enemies that possess explosive attacks, Spits can be used to bomb tinted rocks or open Secret Rooms.
Soul Sucker[edit | edit source]
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 beams in the four cardinal directions after a short delay.
Notes[edit | edit source]
- The Brimstone lasers from the Soul Suckers can damage other enemies.
Trivia[edit | edit source]
- The Black Fly has the lowest health of any enemy in the game, tied with the Corn.
