Binding of Isaac: Rebirth Wiki

Guts is a monster that attaches itself to a wall or obstacle, such as a rock, rolling around the contour of the terrain. If the obstacle it is attached to is destroyed, then it will continue rolling in the direction it was previously traveling until it meets another wall or obstacle.

They make up for their limited movement by being very fast, and in numbers they can tighten movement space (especially in layouts containing narrow passages). Two of them are spawned by Mama Guts upon death.


Scarred Guts[]

Added in Afterbirth

Scarred Guts are paler versions of the regular Guts. They have a chance of replacing normal Guts in the Scarred Womb Scarred Womb. They behave identically to regular Guts but leave behind a trail of damaging Red Creep and move slightly faster than their regular counterparts.


Added in Repentance

Slogs roll around, while leaving a trail of Black creep behind which slows players and enemies movement. However when Isaac is in their line of sight, they charge at him. While Guts and Scarred Guts rotate counter-clockwise, Slogs rotate clockwise.


Added in Repentance

Cysts behave like normal Guts but they will occasionally shoot 1 blood shot towards Isaac if he is close enough.

Two of them will be spawned if a Dead Meat Dead Meat is killed.
