The Blighted Ovum is one of the bosses that can appear in The Cellar, and is the posthumous version of Gemini.

Behavior[edit | edit source]

The Blighted Ovum starts off separated into two parts.

Suture is invincible and slowly floats towards the player, firing a horizontal Brimstone shot whenever the player is to its left or right.
Contusion constantly chases the player and progressively gets faster, while leaving behind a trail of red creep. Unlike Gemini he will not stop for breath, only slow down.

The Blighted Ovum was added in the Wrath of the Lamb DLC for the original Binding of Isaac.
In medicine, a blighted ovum is a pregnancy in which the early pregnancy appears normal on an ultrasound scan, but later no visible embryo develops.
This boss has skin on its body in the boss art, but it doesn't in-game.
