Horfs are disembodied human heads with their eyes gouged out. Horfs remain immobile in one spot, firing blood shots at Isaac when he gets in their range. They will fire shots directly at Isaac when they're about 1/2 room width away from them, even though their shots can travel the entire room's length. This makes it possible to outrange the Horfs in almost all encounters with them; even if you're in range, they have slow rate of fire and their shots are slow-travelling as well, and can be dodged simply by moving slightly to the side.
Psychic Horfs, like to Psychic Maws, are psychic version of Horfs. They shoot homing tears at Isaac when he gets close. Unlike a Psychic Maw, it does not possess an Eternal Fly.
- Psychic Horfs are similar in appearance to the original Spoon Bender in the original Binding of Isaac, as Isaac's eyes would be closed and a magenta flame and eye would appear on Isaac's forehead.
- Mega Maw resembles a Psychic Horf.
- Maws and Psychic Maws appear to be the posthumous versions of Horfs and Psychic Horfs, as their attacks are similar, plus Maws appear to be a rotting Horf.
- Horfs look similar to the head of a Frowning Gaper.
Horf on Isaac's Last Will.
If a Horf or Psychic Horf is stunned
, or frozen
