Polycephalus is a boss that can appear:

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 Needs to be unlocked[]

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