POWERS
❧ Shape-shifting.
(Seen in a human form, a goblin form, and as a barn owl). While we have no reason to suspect that he cannot appear as more things, for simplicity's sake and the purpose of power restriction I will only have him appear in the last human form he took, albeit less glamrock and more survivalist trader.
*Note: Regarding gender because of shape-shifting - Jareth isn't human and despite identifying as male and being titled "King", he is also a shape-shifter and not confined by gendered forms, or even species, though he seems to prefer appearing as a human male, mostly because the objects of his affection obsession have been heterosexual cis-women who are human, and he appears as whoever they desire. Literally, we know this because Sarah's bedroom is covered in Bowie posters, so Jareth appears to her as a form inspired by her favorite rock star.
I say "objects of his affection" rather than just Sarah here because as there have been other babies kidnapped, there have been other humans who have wished it so, and he was bound to have been interested in others of them. Anywhere following that suggests a power limitation tied to Sarah may be implied to mean "whosoever summons him".
❧ Illusion.
Sent in the form of floating crystal balls. They seem to contain everything from dreams to entire illusory worlds. The limits are unknown. This power may later be used in-game with permission from the character's writers, of course. If they choose to allow his illusion-crystal to impact them, we will collaborate on what the illusion is, and how and why Jareth plans to interact with them in this way. In the game, it will be restricted to dreams, with Jareth's intentions in sending them similar to the idea of dream inception. He seeks to manipulate people in any way he can, to get his desired outcome from them, or reach them in a way he feels he is incapable of doing, for whatever reason, in the waking and conscious world.
❧ Inter-dimensional travel.
As far as we know, this has limitations. In the human world, without being summoned, he was only shown as being able to appear in the form of a white barn owl. If summoned, he can appear however he wants. So here, he'll be in his last selected human form, but very confused about his inability to travel elsewhere.
❧ Goblin Command.
Goblins follow his commands without question, despite his complete indifference towards them. They even laugh and burst out into song and dance on demand. What's better than that?
❧ Gravity Defiance.
"I think its time to trust my instincts, close my eyes and leap! Its time to try defying gravity! I think I'll--" ***record scratch*** OK but like literally, he can walk around in an Escher room (stairs going in different directions) and not...fall.
❧ Goblin creation.
He is able to create more goblins by cursing children. To the extent of our knowledge, his kingdom of goblins has entirely come from whatever made him, himself - the original goblin, and then all the children who were cursed just as Sarah's brother Toby would have been cursed, if he weren't saved. Essentially, the goblins are unwanted children who over time turned into goblins. Others may have been cursed to turn into a goblin in circumstances similar to Sarah's quest to save her brother. It is unclear in the canon and essentially left to vague fan speculation. At the very least, he is clearly able to curse beings to turn into goblins.
❧ Omniscience.
In his own domain, he is able to gaze into a crystal and see anything happening anywhere. He can't hear what is being said unless he is physically present, however. When he is watching people, an outline of his face is shown appearing in a rock or a tree or the ground nearby, but no one ever seems to notice. Here, he will only be able to do that in later tiers and if permitted by characters' writers.
*Note: It is possible his omniscience is also just a manifestation of Sarah's intuition, as he is never shown 'seeing' anything outside the scope of Sarah's own awareness, even if whatever is in question is not something she is consciously aware of (yet).
❧ Telepathy.
He is able to communicate with some wayward citizens of his strange kingdom via telepathy, as he does when he intimidates Hoggle near the Bog of Eternal Stench. The extent to which he can do this with other characters in the here will be dependent on if the writer thinks it would be interesting to explore, and power tier levels.
❧ Immortality.
Whether or not there is a way to kill him was never explored in canon. I am sure he can be killed, since though DC should really buy the rights to the character, he isn't one of Neil Gaiman's 'Endless'. Anyone else can be more-or-less "killed". However, he does not appear capable of death by any natural means. Please Gods, give me
Sandman crossovers.
