The Husk

The Husk is a boss that can appear in Catacombs.

Behavior

Moves around the room like The Duke of Flies, but much faster and can perform the following attacks:

Spawns 2 Attack Flies that orbit loosely around it, blocking shots as well as a Spider.
- These flies like the ones spawned by The Duke of Flies can be killed if Isaac walks into them.
- The Husk will not use this attack if there are 8 flies and spiders total spawned but can exceed the 8 limit if it spawns more flies and spiders when just under the limit.
Fires spray of projectiles, similar to Monstro, but with fewer projectiles.
Fires blood shots in 8 directions and spreads the flies orbiting it outwards, freeing them to chase Isaac.
- Unlike the Duke of Flies, the Husk can perform this attack at any time without any required amount of orbiting Attack Flies.
Upon death, all orbiting flies will be free to chase Isaac.
- Spawns a 6-8 random Flies, Attack Flies and Pooters upon death.

Dark Grey: 15% larger with 56% more HP (234). It moves slower and spawns Boom Flies instead of Spiders and Attack Flies. The explosions from the Boom Flies can damage the Husk. Spawns 1-2 additional Boom Flies upon death.
Red: 25% smaller and faster. Rather than spawning enemies, it only does its projectile attacks. Spawns 1-2 additional Red Boom Flies upon death.

The Husk was added in the Wrath of the Lamb DLC for the original The Binding of Isaac.
It is the posthumous version of The Duke of Flies.
In the boss art, The Husk has some missing teeth in its mouth, but in-game, it has extra teeth.
The Husk resembles Pestilence's head.
The Husk resembles the shell worn by Min-Min.
