The basic magical creatures of the Enchanted Forest, the fairies use the fairy dust the dwarves mine to make magic, which doesn't seem to have the same downsides as the dark magic everyone else uses.
  • Colorful Theme Naming: "Quite A Common Fairy" reveals that some of the major fairies are named after the dominant color of their dresses besides having more elaborate, unique names. Tinker Bell was referred to as "Green" by the Blue Fairy until she requested otherwise.
  • Fairy Sexy: All of them so far have been attractive.
  • One-Gender Race: Fairies are apparently all female. In Storybrooke, they are nuns.
  • Our Fairies Are Different: An attractive One-Gender Race that makes magic thanks to the dwarves' aid.
  • Pimped-Out Dress: Every fairy seen has been wearing a very elaborate dress.

A race of male workers and miners who are hatched from eggs.
  • Born as an Adult: They hatch fully grown.
  • Fantastic Caste System: Forced to mine fairy dust, never allowed to leave said mines and are not allowed to fall in love.
  • Meaningful Names: Dwarf names are based on dominant personality traits, which are revealed through magic pickaxes. These names will change if the dominant trait changes.
  • One-Gender Race: Dwarves are one of these—all male, they hatch from eggs fully formed. With clothing.
  • Our Dwarves Are All the Same: Played straight or even exaggerated, since dwarves are born fully grown and conscious after hatching from eggs and are single-mindedly devoted to mining.

Played by: Mark Gibbon, John Rhys-Davies (voice only)

So far, two types of trolls have been seen. The Bridge Trolls in the Enchanted Forest are an angry race of monsters who have issues with human nobles, and who are also intelligent enough to make deals. Meanwhile, the Rock Trolls of Arendelle appear more benign, and try their best to help humans who seek them out.
  • All Trolls Are Different: They guard bridges and hate nobles. Also an In-Universe example: the trolls of the Enchanted Forest are visibly more humanoid than the trolls of Arendelle.
  • Hidden in Plain Sight: Arendelle's trolls can disguise themselves as rocks.
  • Laser-Guided Amnesia: Rock trolls specialize in this; however, they can also reverse the amnesia.

An anthropomorphic race of beings who reside in Oz near the Emerald City.


The "Big Bad Wolf," werewolves are infectious, only vulnerable to silver and immediately fatal wounds, and transform on the three days of the full moon. They also pass their condition along their bloodline.
  • The Dreaded: People know how dangerous they are.
  • Magic Pants: Lycanthropy doesn't damage clothing.
  • The Nose Knows: Werewolves have this even in human form.
  • Our Werewolves Are Different: In this universe, lycanthropy is a hereditary condition as well as a viral one, and its effects fade with age. Werewolves also have enhanced strength, speed, and senses even in their human forms.
  • Super Speed: Another ability they have in both human and wolf form.
  • Supernatural Gold Eyes: Supernatural creatures with golden eyes.


A standard fire-breathing lizard species that appears to be unintelligent. Maleficent can turn into one when it suits her.

Spirits forced to live in bottles and act as stewards of wishes.
  • Genie in a Bottle: They are forced to live there.
  • Jackass Genie: Averted in that it's the magic, not the genie, as the Arc Words are "Magic comes at a price". The genie is even perfectly willing to warn against it.
    • Benevolent Genie: Kind of, but not always; one of them ends up killing the person who freed him, thanks to Regina's influence.

Played by: C. Ernst Harth

Blind, aggressive monsters that have warred with humans before.
  • The Brute: A race of dangerous brutes.

Extremely dangerous spirits that hunt down anyone bearing their mark and steal their soul.
  • Black Cloak: They wear these.
  • The Faceless: Their faces are shadowed.
  • Fan Nickname: As soon as one was seen for the first time, the fandom started calling them Dementors and hasn't stopped. Of course, their soul-stealing abilities doesn't help build much of a case against them.
  • Red Eyes, Take Warning: Glowing red eyes.
  • Your Soul Is Mine: They don't actually kill people. They just remove their souls. The consumed souls go to a netherworld that they can be rescued from; as Mulan and Princess Aurora managed for Prince Phillip offscreen.

  • Back from the Dead: They are dead bodies animated by magic.
