Gushers (潮吹き Shiofuki) are a type of Pacers appearing in The Basement and The Cellar from Chapter 1.


Beside their appearance looking identical to normal Pacers, their stump squirt blood more often.


Gushers wander around a room blindly, similar to Pacers, but will occasionally shoot blood in a random direction. The shot is slow-moving and has short range, and is typically easy to avoid. Gushers are only a threat in large numbers and enclosed areas.

Eternal Champior Behavior

Eternal Gusher moves faster and will keep chasing Isaac. The blood shot it shoots also aims at Isaac.


  • They appear in the original game.
  • Their Japanese name, Shiofuki, translates to "Squirting".
  • From the original game, a champion Gusher will maybe spawn in rooms that there is already Gushers (by replacing the normal one by a champion one) or by killing a champion Gaper/Frowning Gaper (killing a normal one will result in a normal Pacer, normal Gusher or none of them spawning).
  • A champion Gusher still shoots normal-sized blood shots and they deal half heart damage. However making contact with them still causes Isaac takes 1 full heart damage.
