Contents
Behavior[]
Polycephalus burrows underground when Isaac is not within range. While burrowed he becomes invincible and follows Isaac's movements. When close to Isaac, he pops out and performs one of the following attacks:
- Sprays out a cluster of projectiles towards Isaac, similar to
Monstro, but more drawn out.
- Fires a spread of 3 projectiles at Isaac.
- Shoots out 8 projectiles in all directions.
- Summons a
Round Worm.
He will stay vulnerable for a few moments after performing an attack before quickly burrowing underground again.
Champion Versions

◼ Red: Summons
Para-Bites instead of Round Worms. All projectile attacks are replaced with a ring of six projectiles.
◼ Pink: Two Polycephaluses, each with 50% HP (100), replace the normal Polycephalus. They do not spawn Round Worms.

Delirium's forms.
Trivia[]
The Stain is his posthumous version, who also shows up in Chapter 2. Polycephalus is one of four bosses to have their posthumous version in the same chapter, the others being
Gemini having
Blighted Ovum in Chapter 1,
Chub having
Carrion Queen in Chapter 2 and the
Tuff Twins having
The Shell in Chapter 2.5.
However, Polycephalus is the only one of them to have their posthumous version in the same environments as well, sharing both The Catacombs and the
Flooded Caves with The Stain. The only difference is that The Stain can appear in
Caves as well, where Polycephalus cannot.
This is no longer the case as of Repentance, since Polycephalus no longer appears in the Flooded Caves while The Stain no longer appears in The Catacombs.
- Polycephaly is the condition of having more than one head.
- Polycephalus shares his name with a cactus.
- Polycephalus is one of the four bosses that can be spawned by

Scarred Para-Bites if he was fought in the
Scarred Womb.
