Cauldron Born

The Cauldron Born are the undead minions of the Horned King in The Black Cauldron.

Development
As some of the more nightmarish beings in Disney media, considering their undead zombie nature, many of the deleted scenes of the film surround the waking of the Cauldron Born and their attacks. One of the more infamous cuts and one that an image of would find it's way online of would be a scene of the green mist from the cauldron melting the skin off the bones of one of his mortal soldiers.

The Black Cauldron
The primary reason why the Horned King is searching for the cauldron, he is often seen speaking to the dead bodies littering his castle. When the Cauldron finally gets into the Horned King's grasp, he calls upon it's terrible power to awaken the corpses as the army of the Cauldron Born, who proceed to kill all of his mortal minions on their way out of the castle and across the bridge into Prydain. However, they are destroyed when Gurgi sacrifices himself to end the Cauldron's power. In disbelief of his deathless warriors returning to piles of bones, the Horned King attacks Taran before being sucked into the cauldron and destroyed.

House of Mouse
In the episode "House of Magic", the creatures were accidentally unleashed by Daisy Duck when she attempted magic.

Disney Parks
The Cauldron Born appeared at the end of the Cinderella Castle Mystery Tour where the Horned King brought them to life to attack the guests. However, they were defeated alongside their master when a guest is chosen to use a magic sword to destroy the Cauldron and beat the Horned King with it.
