Binding of Isaac: Rebirth Wiki

Added in Repentance

Bot Fly is a passive item added in The Binding of Isaac: Repentance.


  • Spawns a robotic Pooter familiar that orbits around Isaac and fires shielded tears at incoming enemy projectiles, similar to those from Lost Contact Lost Contact.
    • The shielded tears home in on projectiles, but not enemies.
    • The familiar deals 1 contact damage per tick or 3 damage per second, and instantly kills weak fly enemies on contact.
  • This item belongs to the Beelzebub set. Collecting three items from this set will transform Isaac into a giant humanoid fly.


  • Only 5 Bot Flies can circle Isaac at a time.



  • This item's name is a reference to the botfly, a parasitic insect which lives in tropical climates.
  • This item’s behavior and pickup quote is likely a reference to Defense Drones in the roguelike game FTL: Faster Than Light.
