Red Boom Flies roam around the room diagonally, dealing touch damage and releasing 6 blood shots in all directions 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 and release 4 blood shots in the cardinal directions, occasionally spawning a Drowned Charger.
If a Drowned Boom Fly dies while over an obstacle or pit, the Drowned Charger will not be spawned.

Dragon Fly X is identical to the Dragon Fly in behavior, but upon death it spawns 4 lines of fire in the diagonal directions.
Bone Fly[edit | edit source]

Bone Flies fly around the room diagonally, dealing contact damage and firing bones at Isaac when they are lined up, similar to a Bony. Upon death, they shoot 3 evenly spaced bones (one of them aligned towards the closest cardinal direction to Isaac).

Sick Boom Flies fly around the room diagonally dealing contact damage and trailing poisonous gas. Upon death they explode into a cloud of gas and release 6 green shots in all directions.
Tainted Boom Fly[edit | edit source]
