Polycephalus is a boss that can appear in The Catacombs and the Flooded Caves. It is a mass of underdeveloped heads sprouting from a giant half buried one.

Behavior[edit | edit source]

Polycephalus's attacks consist of burrowing underground and then attacking Isaac in a variety of ways.

  • He may spray out a barrage of shots towards the player.
  • He may fire a spread-shot of three shots at the player.
  • He may summon a Round Worm.
  • He may shoot out eight tears around him.

When Polycephalus bursts upwards is random, however the player can delay him appearing by continuing to move, and can force him to appear by standing still. In the latter case Polycephalus will appear directly beside the player.

Champion Versions[edit | edit source]

  • Added in Afterbirth Red: Summons Para-Bites instead of Round Worms. Fires six shots in all directions instead of firing at Isaac.
  • Added in Afterbirth Pink: Two Polycephaluses, each with half health, replace the normal Polycephalus. They do not spawn Round Worms.
