In the film Labyrinth Jareth, the Goblin King has the form of a healthy, handsome middle aged human male, played flawlessly by David Bowie. The rest of the Goblins are all essentially creaturelings of various make, made by Jim Henson's puppet shop. This could mean 2 things:
- Jareth is an "evolved" form of Goblin, that is either similar to or can mimic human form. [This is possible, considering he showed shape-shifting powers in the film by turning himself into an owl. Or...
- Jareth was once human and mortal, but "became" the Goblin King somehow. This could also be possible, as it explains why he would want a human baby; he would need a new heir to take his place.
Was any clear explanation given in-canon?
Note: I know there was a "Sequel manga" of such, but never read it, so perhaps that could spread some understanding as well.
