Thousands of years ago, members of this species faced persecution from other races which feared them for their abilities. As a result, most of them came to reside on a small rogue planet in the Omarion Nebula, located in the Gamma Quadrant.
changeling, in European folklore, a deformed or imbecilic offspring of fairies or elves substituted by them surreptitiously for a human infant. According to legend, the abducted human children are given to the devil or used to strengthen fairy stock.
Changelings have no homeland; they live among humans in Khorvaire, blending in and living in their shadow. Changelings form the backbone of the criminal underworld in Khorvaire's large cities. Some work as entertainers, inquisitives (investigators and mystery solvers in the world of Eberron) and government agents.
The Changelings are the highest order in a Gamma Quadrant faction known as the Dominion which is composed of at least four distinct species. Within the Dominion, the Changelings are known as "The Founders" and are greatly feared.
They don't. Changelings seem closer to a colony organism than anything else. Kind of like coral, or maybe a sea sponge. The colony doesn't directly reproduce, it just grows bigger as the microorganisms which make it up undergo mitosis.
The Changelings were sent to retrieve Picard's body so that they could specifically remove parts of his parietal lobe—the part that was supposedly defective from Irumodic Syndrome.
As crew members beamed on and off their ships, the computers recognized this new genetic code as "common biology" and integrated it into the DNA of every officer in the fleet. The Changelings wanted Jack because of they needed his Borg-altered DNA, though they later ended up acquiring this from Picard's body.
Are they biologically asexual and just choose their current sex with shapeshifting? Yes. What's been stated in the past is that changelings set their sex with shapeshifting.
Unlike ponies, changelings do not have cutie marks. Following their metamorphosis in To Where and Back Again - Part 2, changelings have varied coat colors and insect characteristics, such as Thorax and Pharynx's horns, and they no longer have fangs or holes in their bodies.
Queen Chrysalis or simply known as Chrysalis, is the former Queen of the Changelings who seeks to feed her subjects' hunger for love and expand her rule across Equestria in the process and one of the main antagonists of My Little Pony: Friendship is Magic.
They have large colorless eyes circled by thick black rings. Their hair color is most commonly a light shade of silver followed by platinum and blonde. In rarer cases, their hair can be pale shades of green, pink, and blue. Similar to elves, changelings lack body and facial hair.
A changeling can't make the wings at all. If they had wings, like from a class feature or something, then they could look like an Aaracokra with wings because they will have those limbs at that point.
Changelings have red blood like a majority of the other races. Bleeding around others may alert many that the Changeling is not of the same race (should the blood color vary). For this reason, a Changeling will usually choose to take the form of a race with red blood.
Since most of the supernatural beings of Scandinavian folklore are said to be afraid of iron, Scandinavian parents would often place an iron tool such as a pair of scissors or a knife on top of the cradle of an un-baptised infant to prevent its being abducted by the trolls.
If you're Irish, you know your child is a changeling if it's sickly and doesn't grow in size like a normal child. Another fairly obvious sign is if it grows a beard or has long teeth. Finally, your child might be far more intelligent than other kids that age, and possess unusual insight.
Most often, the mother begins to carry twins, and one of the twins is a changeling. There are extremely rare cases of being born alone, or as part of triplets. In the rarest of cases, the other twin is a hag.
Within this description there are variants of changelings that show subtle differences. Some have opalescence in their skin (as if it contains various colors instead of just being white) and their eyes can be completely black.
Changelings born from two changeling parents are born in their natural form: pale, slender, with colorless eyes and white hair.
As for being tattooed, changelings can definitely be tattooed, and they can just as easily erase the tattoo with a moment's thought.
A changeling can alter his or her gender (and reproductive abilities) as part of using the race's minor shapechange ability. Two changeling parents breed a changeling child. A changeling and a humanoid can mate to produce an offspring with the child having a 50% chance to be of either race.
Changelings typically have large eyes with narrow pupils, ranging in color from white, to yellow, to black. Hair colors are similar: Light grey, platinum blonde, shades of silver, all the way to the darkest hair color being a light brown.
Changelings were fairies who had been left in place of a human child or baby who had been stolen by the fairies. The child was taken for one of three reasons; to act as a servant, for the fairies to receive the love of a human child, or for malice/revenge.
Even when in humanoid form, Changelings did not need to take in sustenance. Odo noted that he once attempted to eat after assuming humanoid form for the first time, but found the experience not only unsatisfying due to his lack of taste buds, but "messy" for reasons he chose not to elaborate.
Changelings are largely equine in appearance but possess insect-like characteristics. Originally, they had black carapace-like coats, webbed manes and tails, blue reflection-less eyes (unlike their queen's), fangs, bent horns, jagged ears, insect-like wings, and holes in their legs.
Changelings don't inherently recognize each other. If they don't want to be recognized then when they do something suspicious it would be an insight check against the changelings deception, which the changeling has advantage on. A changeling could have expertise in insight from divergent persona.
