Creeper is the (former) secondary antagonist from Disney's The Black Cauldron. He is a goblin who used to serve as The Horned King's right-hand until the latter's defeat.
He was voiced by Phil Fondacaro.
Creeper is one of the henchmen of The Horned King living in his castle. He is constantly abused by the Horned King, who blames Creeper for things going wrong (even if it wasn't Creeper's fault) and chokes him when he thinks Creeper isn't doing what he wants him to do.
Creeper first appears during the celebration of the capture of Taran and his pig Hen Wen. Afterwards, Creeper is ordered to to force Taran to have Hen Wen show the location of the Black Cauldron. Creeper succeeds, but as the Horned King arrives to see the location, Taran, afraid of the Horned King's scary face, pours the liquid of the revelation of the Black Cauldron into the Horned King's eyes. An angry Creeper orders the Horned King's men and the gwythaints to chase after Taran and Hen Wen. Though Creeper personally manages to capture Taran, Hen Wen has already escaped into the moat, and the Horned King believes that Creeper let her go (despite Creeper truthfully saying that wasn't the case) and strangles him briefly before ordering his men to throw Taran into the dungeon.
Creeper appears again when he angrily orders a henchmen to move a rolling basket full of dead people, all of which have been murdered by the Horned King's men. Creeper and the men soon learn that Taran and his friends Princess Eilonwy and Fleudder Flam have escaped their confinement, so they chase them. However, thanks to a magic sword Taran has claimed from a tomb inside the castle, Taran and his friends were able to escape, much to Creeper's shock. Knowing that the Horned King will be very furious, Creeper reluctantly strangles himself after confessing what happened, but the Horned King is quite impressed, knowing that Taran will be looking for Hen Wen (and the Black Cauldron), so he orders Creeper to sends the gwyithaints to follow Taran. The gwythaints manage to locate Taran and his friends after they found the Black Cauldron, allowing the Horned King's men to capture them and steal the Cauldron.
With the Cauldron finally under the Horned King's possession, Creeper taunts Taran and his friends for leading the Black Cauldron to the Horned King. He then watches as the Horned King uses the power of the Cauldron to bring all the skeletons to life to create the Cauldron Born, which terrified everyone, even the Horned King's men ran away in fear after the undead skeletons killed two of them. As the Horned King orders his undead army to destroy everything in their path, Creeper escorts him to a balcony to get a better view.
Though it would've seemed that the Horned King is about to achieve his victory, this was cut short when Gurgi sacrifices himself into the Black Cauldron, reversing the spell and causing the undead skeletons to lose their power and die. The angry Horned King blames Creeper and strangles him, planning to throw his body into the Cauldron to revive the undead army. However, as the Horned King tries to get his undead army to rise again, Creeper spots Taran trying to escape and informs the Horned King, saying that Taran is to blame. Finally understanding what was really happening, the Horned King throws Creeper away before turning his rage towards Taran for foiling his plans. However, Taran pushes the Horned King into the Black Culdron, as its powers are being sucked up thanks to Gurgi's sacrifice. Creeper can only watch his master screaming in agony as the Cauldron's power kills the Horned King and blows his corpse into bits. As first, Creeper is horrified by this, but realizes that he has been freed from the Horned King's abuse, as he won't be punished for anything (whether it be his fault or not). Delighted by the Horned King's death, Creeper laughs triumphantly as he escapes from the exploding castle caused by the cauldron's power.
As Creeper leaves, he manages to save a gwythaint from dying in the destruction of the castle. He is last seen riding off with the gwythaint laughing while holding out two fake horns to taunt his former master.
Creeper is intelligent and fiendish, and is very loyal to the Horned King, but is also deeply afraid of him due to his mistreatment of him. Notably, Creeper is soon happy with the Horned King being killed.
- Creeper is similar to Professor Ratigan's nasty bat sidekick, Fidget from The Great Mouse Detective.
- He is one of the few characters created for the movie as he wasn't derived from the Prydain book series.
