Gurgi is the deuteragonist in Disney's horror adventure thriller fantasy-comedy film The Black Cauldron. He is portrayed as an eldery, small badger-like creature whose speech distortions somewhat resemble those of Donald Duck. The voice is provided by actor/impressionist John Byner.
Gurgi loves Taran, but is not loved much in return. He helps him find the titular Black Cauldron, but the witches who guard it warn that it is indestructible and negating its power requires self-sacrifice. At the climax of the film, Gurgi is the only one who avoids capture by the evil Horned King. He sneaks into the Horned King's castle unnoticed and rescues his friends, but by then the Horned King has used the titular Black Cauldron to summon his undead "cauldron-born" army.
Taran resolves to throw himself into the Cauldron, but Gurgi stops him, sadly saying "Taran has many friends...Gurgi has no friends". With that, he jumps into the Cauldron and sacrifices his own life, much to Taran's horror. The Cauldron, now out of control, destroys the Horned King and his castle while Taran and the others escape. The witches come to reclaim the now-inert cauldron, and Taran agrees to give it back in exchange for Gurgi's life. The witches claim that's impossible, but reluctantly comply when Fflewddur Fflamm challenges them to show off their power. As a result, Gurgi is revived. He playfully makes Taran and Princess Eilonwy kiss, and they head home.
