|Odo and the female Changeling link together (2374)|
|Odo and Laas (2375)|
- For the Earth legend regarding a Changeling child, see Changeling (folklore); for the TOS episode, see "The Changeling".
In its natural state, a Changeling's body was a formless gelatinous mass, to which it had to revert every eighteen hours (Odo's example) in order to regenerate. (DS9: "The Forsaken", "The Storyteller", "The Alternate", "In Purgatory's Shadow") If a Changeling remained in solid form for longer than sixteen hours, their body began to deteriorate and peel or "flake" away.
Changelings could take virtually any corporeal form, ranging from humanoid aliens to fog to reflective surfaces. They did not seem to be able to exist as or change to forms of energy. (DS9: "Chimera", "The Way of the Warrior") They, or at least the Founders, also had the ability to closely mimic humanoid personalities to the point where even close friends and family often could not distinguish them from the originals. (DS9: "By Inferno's Light", "Apocalypse Rising", "Paradise Lost") They could transform parts of themselves into smaller electrical devices, like a combadge, and make it operational, and were also capable of at least mimicking the shape and operation of a computer. Changelings could also mimic the form of fire and clouds. (citation needed • edit)
Starfleet sensors, as of 2371, failed to recognize Changelings when they mimicked other forms. The Obsidian Order created a prototype quantum stasis field generator that could prevent a Changeling from shape shifting. (DS9: "The Adversary", "The Die is Cast")
Changelings – or at least Odo – had no sense of smell. (DS9: "If Wishes Were Horses", "Improbable Cause") Laas stated, however, that if his hands had Klingon blood on them, they would emit a stench, showing that after living among solids for years, he was at least familiar with the concept. (DS9: "Chimera")
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 tastebuds, but 'messy' for reasons he chose not to elaborate. (DS9: "Meridian")
A telepathic energy matrix (which caused the crew of Deep Space 9 to fight for control of the station) was rejected by Odo's lack of a humanoid brain. It did have the ability to warp his face and knock him unconscious, though he retained his humanoid shape. (DS9: "Dramatis Personae")
There was an apparent telepathic aspect to the species, evidenced in Odo's being drawn toward the Omarion Nebula, which was once home to the Founders. (DS9: "The Search, Part II") However, it is possible that the instinctive desire to visit the nebula was "hardwired" into him. Changelings had the ability to sense, in most cases, the presence of other Changelings. (DS9: "The Search, Part I", "Homefront", "Chimera") The Jem'Hadar may also have the ability to sense Changelings, though this ability might not be telepathic but an imprinted response to a Changeling's gelatinous state, as a child Jem'Hadar who sensed Odo did not respond to him until he temporarily reverted to that state. (DS9: "The Abandoned")
Further suggestion of a telepathic trait arose when Odo's remaining morphogenic enzymes were stimulated by a plasma field, creating a miniaturized "Great Link" with Benjamin Sisko, Jadzia Dax and Elim Garak. (DS9: "Things Past")
At the very least, there exists a "hive mind" among the species when joined with the Great Link. (DS9: "The Search, Part II", "Broken Link", "Sacrifice of Angels", "Chimera") For instance, Odo once commented, "During the Link, I sensed that the other Changelings were trying to hide things from me... faces, names." (DS9: "Broken Link")
The Founders of the Dominion were Changelings, and made up the majority of the Dominion's leadership. Changelings preferred to think of themselves as a drop (the individual) in the larger ocean (what they called the Great Link). A Changeling, therefore, typically had little sense of individual identity. Being a liquid-based lifeform, in order to link with other Changelings, they simply reverted to this state and the liquid blended together, creating a link between them. (DS9: "The Search, Part II")
It has been suggested that Changelings are biologically immortal and therefore never die of old age. (DS9: "Children of Time", "Behind the Lines") However, it has been proven possible to kill Changelings by a number of means. Severe cases of radiation poisoning can prove fatal. (DS9: "The Adversary") Changelings have also been killed by phaser or disruptor fire, at sufficiently high settings. (DS9: "Crossover", "Apocalypse Rising") A Changeling has also been observed succumbing to trauma following the impact of a ship crashing into a planetary surface (a crash in which the ship's intertial dampeners had failed). (DS9: "The Ship")
According to the Founders, the Changelings were once peaceful explorers, but they were persecuted by some of the solids, and they came to believe that the only way to protect themselves was to conquer those around them. Solids (mono-form solid species) called the Founders "Changelings" as an insult, but the Founders took the name for themselves as an act of defiance. (DS9: "The Search, Part II")
Long ago, the Founders sent out one hundred infant Changelings in order to gather information and explore, to return later and share what they had learned. The Founders did not expect any to return until the late-27th century. Odo and Laas were among the hundred. (DS9: "The Search, Part II", "Chimera")
The Changelings seemed proud of their heritage and considered themselves subtly superior; in contrast, Odo (who had been separated from his people for most of his existence) was almost their polar opposite, experiencing self-doubt and internal conflict regarding his people's warlike nature. (citation needed • edit)
Mirror universe Edit
In the mirror universe, the Bajoran wormhole remained undiscovered as late as 2375, therefore Changelings and other species native to the Gamma Quadrant remained unknown to the peoples of the Alpha Quadrant. The only exception was Odo, who was killed on Terok Nor during a workers' revolt in 2370. (DS9: "Crossover")

Background information Edit
- Changelings other than Odo were first mentioned in DS9: "Vortex". They were referred to again in DS9: "Shadowplay", before being introduced in DS9: "The Search, Part I".
- DS9: "Chimera" suggests Changelings have a lifespan of at least two hundred years, although if Odo was indeed two hundred years old when he traveled back with the USS Defiant in an alternate timeline in DS9: "Children of Time", that would indicate Changelings could live for at least four hundred years. It has also been suggested that Changelings might be immortal, with the Female Changeling remarking, "You are a Changeling, you are timeless" – a logical assumption, given that Changelings don't appear to have any cells that might decay over time.
- Though Odo and Laas have been described as male and the Female Changeling as female, it is unclear what anatomical differences, if any, exist between male and female Changelings. Also, although an infant Changeling appeared in DS9: "The Begotten", it was never made clear exactly how Changelings reproduce. The most popular theory is that they reproduce asexually, and simply maintain a male or female form to make it easier for other species to relate to them. At one point, Odo assumed the form of the Female Changeling, which would support this hypothesis. (DS9: "Tacking Into the Wind") Odo did display romantic affection for some female humanoids, most notably Kira Nerys, and was capable of sexual intercourse with humanoid species, but wasn't able to reproduce. He even had a sexual encounter with the Female Changeling, suggesting that two Changelings can mate in humanoid form, though the Female Changeling considered this version of intimacy unnecessary for their race, and pale compared to the Great Link. (DS9: "A Simple Investigation", "Favor the Bold")
- The Changelings frequently assumed a form similar to that of Odo; however, Odo's unique appearance was the product of his difficulty with assuming convincing humanoid forms, not mandated by his racial makeup. Since other Changelings have no difficulty with assuming convincing humanoid forms, they must therefore assume an Odo-like form out of choice. This may be because, before meeting Odo and the races of the Alpha Quadrant, they had no need to reveal themselves individually to outsiders, and thus had no need for a unique humanoid form to differentiate themselves from other species. Odo would have provided them with a useful template. Ronald D. Moore commented, "Odo modeled his look after Dr. Mora and the Founders then modeled their look after Odo. They did this initially as a compliment and way of reaching out to their long-lost Changeling, and later they kept doing it as a dig and reminder to him of his own limitations." (AOL chat, 1997)
- Although much older than Odo, Laas also seemed to have similar facial features, probably because of the same reason. Having been found by the Varalans, it can be assumed that the unique bumps on his forehead are typical Valaran features. (However, Odo doesn't have the Bajoran facial features of Mora Pol and other Bajorans; he comments in DS9: "Past Prologue" that he always had trouble with their noses.)
- The Female Changeling appears to be left-handed in "What You Leave Behind". However, Odo seems to be right-handed during the course of the series. It is unclear whether a Changeling has a dominant hand when assuming humanoid form, or simply chooses which hand to use for different tasks.
- Odo assumes the shape of a computer in "Paradise Lost", but it is unknown whether he could simply mimic the computer's form or whether he could actually perform the complex calculations a computer makes.
- Changelings do grow physically, to a point; as Changelings don't eat or drink, it is unclear exactly where the 'new' mass and energy come from. Julian Bashir asked Odo for a sample of his liquid form, and Odo only agreed on the condition that he would get it back after Bashir's tests were complete.
- Ira Steven Behr was unimpressed with a plot point in DS9: "The Alternate", which suggested that a malevolent Changeling (who, in the episode, turns out to be Odo) is responsible for several attacks on space station Deep Space 9. "The red herring didn't quite work for me all that much," Behr commented, "but it's window dressing [....] It doesn't annoy you because you're buying the package."
