It has 22 HP per segment.

Behavior[]

The number of individual The Hollow bodies that can spawn each fight can vary from 1-4. The most common encounter with The Hollow is with 2 bodies.

  • Flies around the room diagonally, bouncing off of walls.
    • The Hollow appears to travel faster when moving at verticle angles compared to horizontal.
    • The Hollow can change direction if it collides with Isaac.
  • Occasionally spawns poop while moving.
  • The Hollow's segments can be split into smaller copies of the boss as long as the new Hollow segments are longer than 2 pieces.

There is a chance that a Grub can spawn alongside a shorter Hollow (basically replacing a second Hollow).

  • Gold: 15% larger and has 25% more HP (27.5) but retains the same movement speed. Each segment that isn't the head will drop a coin on death.
    • The head will drop a coin only if killed immediately after spawning.
  • Green: Chance for each segment that isn't the head to spawn a Charger on death. Occasionally stops movement to shoot 3 bullets at wherever it is facing.

Notes[]

  • Removed in RepentancePoop spawned by The Hollow will never drop pickups, even when in possession of  Petrified Poop.
    • Added in RepentancePoops spawned by The Hollow have an incredibly low chance to spawn pickups. This chance is not affected by Petrified Poop.
    • Leaving the room and returning will make the poop generate pickups normally.
  • Piercing tears make fighting The Hollow much easier, as each tear can damage multiple segments.
    • Added in Repentance Piercing shots no longer damage segmented enemies multiple times per attack.

Trivia[]
