Added in Repentance

Colostomia is a boss introduced in The Binding of Isaac: Repentance and can appear in Dross Dross.

Behavior[]

Phase 1[]

Colostomia alternates between the following attacks:

  • Hops in place and then slides toward Isaac in the closest cardinal direction, firing projectiles in both perpendicular directions as she moves and leaving trails of explosive gas.
    • The slide can be at a slight angle if Isaac isn't perfectly aligned with it.
    • Colostomia continuously performs this attack until ~40% of the room is covered in explosive gas.
  • Launches a 15►Butt Bombs Butt Bombs Bomb towards Isaac that ignites any gas clouds its explosion hits, causing a chain of explosions.
    • This is always her first attack upon spawning.
    • Unlike Isaac's Butt Bombs, these do not fog the room.

Phase 2[]

After dropping to half health, the bag containing Colostomia explodes, creating explosive clouds and leaving her adhering to the floor.

  • Jumps to another nearby location, firing 8 projectiles in a radial burst and creating a puddle of harmful Brown Creep where she lands.
    • Only 2 puddles of Brown Creep can persist at once.
  • Spits two 15►Butt Bombs Butt Bombs Bombs at Isaac. The range of these bombs is dependent on how close Isaac is to her.
  • Farts, creating a ring of explosive gas around her location.

Trivia[]

  • Colostomia is based on a Colostomy bag, a removable, disposable bag that attaches to the exterior opening of a colostomy to permit sanitary collection and disposal of bodily wastes.
  • Colostomia's 1st phase charge attack is similar to an attack from The Witness in Antibirth.
  • Colostomia is confirmed female according to messages from Not Your Sagittarius in the official Binding of Isaac Discord.[1]
  • Upon death, Colostomia diffuses into the water of the arena, turning it from green to a murky brown.
