The Changelings were Aliens controlled by the Graske that mimick a lifeform and send the real person to Griffoth. They appear exactly like the original, but their eyes flash a greeny-gold colour occasionly. (DW: Attack of the Graske)

Changelings are a species of shape shifting lifeforms from the Gamma Quadrant.
They were noted for their capacity to alter their form to levels that were beyond that of similar shape changing species such as the Wraith, Vendorian and Chameloid races. (TLE novel: Night of the Wolves) In their most basic state Changelings resemble a golden translucent liquid. (DS9 episode: "The Search") This gelatinous substance which was held in a morphogenic matrix that activated into different shapes and textures through the use of a special enzyme. This allowed a Changeling to adopt any shape and texture that they desired so long as they studied the shape long enough. They were unable to mimic an object through a simple glance and were required to see enough of the item or person they wished to copy in order to perfectly take its form. But, by doing so, they were able to create a sophisticated facsimile of flesh and matter; allowing them to even take on clothing. (ST reference: Aliens) Changelings can take on almost any form; liquid, solid, gas and even plasma such as flames. Their abilities are limited mainly by their mass: they comfortably take on humanoid forms, but can also take the forms of things somewhat larger, and a great deal smaller. (DS9 episode: "The Search") The level of mimicry was so accurate that no known scanning technology was able to detect a Changeling once it had adopted a chosen form. (ST reference: Aliens) When a Changeling takes a form - such as a rock - Federation scanners would read the Changeling as a rock. (DS9 episode The Adversary).
However, any piece of the mimicked item that was separated from the main body such as blood samples reverted back to their gelatinous state. (ST reference: Aliens) Any portion of a Changeling's body that becomes separated from the main body reverts back to its natural state. The fact that a person was bleeding was often accepted as proof that a person was not a Changeling as if they were their blood would've reverted to its natural state. (DS9 episodes The Adversary, The Way of the Warrior, and Homefront). Furthermore, phaser's that were set on heavy stun were able to force a Changeling to revert to its natural form. In addition, a Changeling that was killed also changed back to its true shape. (ST reference: Aliens) In addition, a special quantum stasis field was capable of preventing a Changeling from altering their form. (DS9 episode: "The Die is Cast")
Whilst they were capable shapeshifters, a Changeling was required revert to its liquid state every sixteen hours to regenerate. (DS9 episode: "The Search") At such a time, they had to spend least a single hour a day to revert back to its gelatinous form whereupon they rested and rejuvenated. They were able to resist this for a limited amount of time but they would eventually forcibly revert against their will and be unable to take a shape until they had rested. Some Changelings were capable of withstanding this reversion longer than others with some being noted as being able to last a week before changing back to their gelatinous state. (ST reference: Aliens)
Changelings often had an intense desire to merge together and join the Great Link; typically this was at least once a week if not more frequently. (ST reference: Aliens) In order to accomplish this, they simply reverted to their liquid based form and merged together whereupon a link was established as their forms blended together. (DS9 episode: "The Search, Part II") Only foundlings were usually able to resist this urge which was due to the fact that they had been raised without knowing of the Link and thus retained some degree of individuality. This was often an alien concept to the other members of the Great Link. (ST reference: Aliens) As such, they often thought of a single member of their race as a drop in a larger ocean and thus saw little sense in individual identity. (DS9 episode: "The Search, Part II")
The morphogenic matrix of a Changeling was not perfect and it was capable of suffering from instabilities that could threaten their lives. A Changeling was able of being infected by disease and could spread this instability to the rest of their race through the Link thus threatening the entire species with such an ailment. (ST reference: Aliens)
The thoughts and emotions of Changelings could not be read by telepathic races such as the Betazoids. (DS9 episode: "Fascination") They were also able to survive in the vacuum of space, and were highly resistant to disruptor fire. (DS9 episodes: "Chimera", "Apocalypse Rising") The unique nature of the species meant that were were resistant to Borg assimilation. A Changeling was simply able to compress themselves and eject any nanoprobes within herself without any ill effects to them being seen. (DS9 novel: Mission Gamma: Lesser Evil)
The main concepts of the Changelings that make up the Founder's often desire are order and discipline. They abhor chaos and thus seek to control it which they do so by oppressing the races that foment it. Initially, they were a race of explorers that long ago had a natural curiosity about them that made them search the galaxy but relentless persecution and suspicion over their shape changing abilities have made the Changelings a bitter species. They were noted as being one of the most secretive of races in the universe due to their natural distrust of Solids; the mono-form species that have persecuted them for centuries. Thus, they remain out of sight from all beyond their genetically engineered minions such as the Vorta and Jem'Hadar both of whom worshiped them as gods.
A typical Changeling did not form an equal relationship with a member of another species as they were often a race apart with Solids. Being badly spurned by humanoids, Changelings are normally too bitter to trust the Solids again. Thus, they find solace amongst their own kind for only they could join them in forming the Great Link. It was even long said that no Changeling had ever harmed another which was another reason for this explicit trust in their own kind.
Despite their mistrust of other races, the Changeling still maintained their curiosity of the universe around them. Thus they sent a Hundred infant members of their kind into the galaxy in order to learn more about it by being raised by Solids. However, they were also implanted with a desire to return home and share their experiences with the Great Link. Most of these foundlings often found their way back home where they joined their society willingly; abandoning their past lives along with the friends in order to share in the communal life of the Great Link. These young Changeling were sometimes victims of persecution amongst the races they ended up living with and their experiences often reinforced the Great Link desire to rule the Solids rather than be allowed to be hurt by them. Changelings rarely argued with one another and readily conceded their views to another's greater wisdom or insight. If there was ever any doubt than they simply Linked with one another and through the merger their thoughts and forms became one. In this state, it was easily determined he was fit to lead in a given situation.
Changelings were keen observers of solid behavior. This was not only due to their natural curiosity but also due to their need to protect themselves for they had to understand those they had to enforce order on or otherwise lose control over them. By deeply understanding a species and have intimate knowledge of them, a Changeling was capable of assuming a false identity amongst them with ease. Their time amongst these species does not color their views for deep down they understand that all solids are driven by fear and misunderstanding thus eventually leading them to turn on the Changelings if their existence were truly known. Thus, ironically, by attempting to defend themselves from persecution, the Changelings had become the very beings that Solids had feared.
Within the Dominion, the Changelings that make up the Founders know all the languages of their subject races. Thus, they knew Dominion Standard, Vorta and Jem'Hadar. The infiltrator Changeling also adopted the languages of the cultures they were targeting. Ultimately, however, Changelings had no need for language for their own and instead linked with one another giving them a greater level of communication than words could ever give them. The lack of a spoken language meant also that they typically did not have names for they had no need for them. However, in an attempt to better operate amongst Solids, a Changeling will adopt a name for themselves. (ST reference: Aliens)
The origin of the Changeling was unknown though according to the Female Changeling they were once a monoform based species until they evolved. According to the elderly Changeling Indurane, their race begun with a semi mythical being called the Progenitor which created the universe and everything in it according to their beliefs. This entity was noted to have taken a population of "solids" and imbued them with its own malleable characteristics which led to the creation of the Great Link. After which, the creature departed known space leaving the Changeling incapable of reproducing though with lengthy life spans. (DS9 novels: The Dominion: Olympus Descending, Warpath)
The race embarked on a period of exploration of the galaxy due to their natural curiosity. However, they found themselves hunted and killed by distrustful solids who feared their shapeshifting abilities. Thus, the population of Changelings came together on an unnamed planet in the Gamma Quadrant and called themselves the Founders. This group thus sought a chance to protect themselves by dominating the solids that would wish them harm. In order to accomplish this, they formed a mighty empire called the Dominion which they ruled as gods. (DS9 episode: "The Search") One Changeling was noted to have been wounded on an unknown world whilst being chased by an angry mob of solids. This Changeling was given shelter and cared for by a family of small primates and in gratitude the Changeling promised the creatures that they would be part of a mighty empire in the stars. Those primates were genetically engineered to become the Vorta who became important administrators of this empire. (DS9 episode: "Treachery, Faith and the Great River") Similarly, the Jem'Hadar were genetically engineered to serve as the enforcers and soldiers of the Founder's will. (ST roleplay module: Aliens)
Prior to and during the Dominion War the Federation and its allies used blood screenings in an attempt to ferret out Changelings. However screenings proved to not be very effective. The Martok Changeling cut himself and allowed blood to pool on Deep Space Nine's wardroom table to make Captain Benjamin Sisko and Major Kira Nerys believe that he was actually General Martok. Joseph Sisko later offered the opinion that Founders on infiltration missions would maintain a supply of real blood within them to use in such instances. (DS9 episodes The Adversary, The Way of the Warrior, and Homefront).
The majority of the Changelings that made up the Great Link nearly faced extinction when they were infected with a morphogenic virus by a secret intelligence wing within the United Federation of Planets which was called Section 31. They intended to wipe out the Founder's and end the threat posed by the Dominion by committing genocide and accomplished this by infecting Deep Space 9 security chief Odo with the virus in order for him to serve as a carrier for the disease. However, he was eventually cured by the efforts of Doctor Julian Bashir and Odo eventually cured the Female Changeling thus saving the race from extinction as well as ending the Dominion War. (DS9 episodes: "Extreme Measures", "What You Leave Behind")
In 2376, a Changeling was left stranded on a world after her vessel crashed onto the unnamed planet. When the USS Defiant led by Captain Elias Vaughn came to rescue her they noticed that an assimilated Borg vessel was on the planet as well. The drone attempted to assimilate the Founder but she simply compressed herself and the nanoprobes whereupon she ejected a ball of nanoprobes with no ill effects to herself. (DS9 novel: Mission Gamma: Lesser Evil) In the same year, the Changelings attempted to coax the Progenitor to return to them but witnessed its death at the hands of the Ascendant's. Consumed with guilty over sending the Hundred away, the Changelings dispersed and decided to live in isolation; even from their own kind. This left only a small number of the race left behind to continue leading the Dominion. (DS9 novels: The Dominion: Olympus Descending, Warpath)

As a child, Garfield Logan contracted with a rare illness called Sakutia and was cured by a serum from a green monkey. This serum had the unintended effect of turning his skin and hair green and gave him the ability to change into any form. 
Originally and currently known as Beast Boy, he was adopted by Elasti-Girl and Mento, members of the Doom Patrol. He later joined the West Coast team of the Teen Titans (known as Titans West), and was part of the New Teen Titans assembled by Raven. It was at this time that he took the name Changeling. He remained with various incarnations of the team, forming a close friendship with Cyborg.
He later began using the name Beast Boy again.  Following a failed attempt to recreate "Titans West" as "Titans L.A.," he rejoined the main team.
He has also worked as an actor, playing the role of an alien in the TV series Star Trek 2020.
Whatever team he is part of, he likes to joke around with people and make jokes of the situations the team get themselves into. However, this is only a facade. In reality, Beast Boy is a boy who has suffered many hardships in his life (both his real parents have passed away, and then his foster mother, whom Garfield became very close to, died in battle along with virtually all of the other Doom Patrol members. He was also part of the team. Also, his foster father was driven mad by a helmet he used to fight enemies). He also has lost many teammates and fell in love with Terra (a member of the Teen Titans) and was heartbroken to discover that she was a traitor working for Deathstroke and hated the Teen Titans with a passion. Even after her death, he refused to believe for a long time that she was a traitor and blamed Deathstroke for corrupting her and using her. As a result of all of this, he uses his jokes to cover the fact that he is scared of losing anyone else he is close to. Despite all of his hardships though, Garfield is friendly and upbeat.
In the "Titans of Tomorrow" adventure, wherein the Titans glimpsed a grim, possible future, Beast Boy had changed his name to Animal Man (II) and fought alongside his fellow, fascist Titans to make the United States a police state. This future Beast Boy is shown as feral shaggy, and more bestial in appearance. He is also characterized as still bearing a grudge against a possibly-resurrected Terra, who, in this future, is a member of the more benign rival group Titans East.One Year Later", they have apparently separated. After trying to hold together a ragtag band of Titans, once Robin returned Beast Boy left the team to rejoin the Doom Patrol and aid his adoptive parents. Following attacks on various former Titans, it was determined that the sons of Trigon were trying to destroy the group to establish a name for themselves. The Titans decided to reform to combat the threat. At the same time, Beast Boy tried to reconcile with Raven.

Beast Boy appears in the Teen Titans animated series, voiced by Greg Cipes. In the series, Beast Boy (nicknamed "BB", and others) plays the role of the lighthearted jokester of the group, though often the butt of many jokes himself (similar to his comics self). He wears his old black and purple Doom Patrol uniform, complete with gray gloves and purple sneakers with seemingly velcro straps. Like with the other Titans, his appearance is much younger than in the comics. Also like in the comics, Beast Boy has the ability to transform into any animal he sees. His favorite forms are a Pterodactyl (for flight and transporting his fellow Titans) and a Tyrannosaurus (for heavy-duty combat).
Beast Boy is generally portrayed as a carefree, scatter-brained and immature personality. He is prone to making jokes no one but himself (in particular, Raven) can laugh about, and generally displays few intellectual-based interests and little sense for tact (though on occasion, however, particularly in the fifth season, Beast Boy does show hidden intellectual and leadership qualities). His carefree behaviour is most likely conditioned by his resignation from the Doom Patrol, where Mento's harsh discipline and less than encouraging attitude had not allowed any free-wheeling. Beast Boy's closest friend among his teammates is Cyborg, with whom he shares a passion for video games and movies. Likewise they are prone to quarreling, especially about their diverging tastes in food; Beast Boy is a vegetarian who never gets tired about persuading his teammates into adopting his culinary tastes as well.
Like in the comics, Beast Boy also had a romantic relationship with Terra who had the power of Earth manipulation. As in the comic book, Terra betrays the Teen Titans as an ally of Slade (Deathstroke). Ultimately, she receives redemption in helping the Titans defeat Slade; however, she is turned to stone in the process. In a departure from the comic book, Beast Boy retains strong feelings for Terra. In the final episode "Things Change", Beast Boy encounters a girl looking like Terra (although it is unclear whether or not it was the real Terra, as he was the only Titan who saw her), apparently suffering from amnesia.
In the Season 3 episode "The Beast Within", Beast Boy is seen in a newly-gained "Super-Werewolf" form when he was doused with an experimental DNA compound. Beast Boy dislikes this form and refrains from using it again until he and the other Titans are fighting off Slade's fire-soldier army in "The End: Part 1" when they have to use their most powerful abilities to defeat them. He never uses it after then, suggesting that even with the strength and abilities it gave him, he considered it a "last resort" to be used.
Season 5 of Teen Titans focuses on Beast Boy a great deal, as it deals with his history as a member of the animated series' incarnation of the Doom Patrol. Until "Homecoming", in which his former teammates make a guest appearance, Beast Boy was the only member of the Doom Patrol to appear on the show. In the second episode of the fifth season, Beast Boy becomes the first male Titan in the series to be explicitly referred to by his real name (Garfield). In "Titans Together", Beast Boy leads Herald, Jericho, Pantha, and Más on an assault on the Brotherhood of Evil. He remains the leader even after other Titans such as Cyborg, Starfire, and Raven join the fight, and only stands down from leadership when Robin is thawed.

This character is or was primarily a member of the younger superhero team known as the Teen Titans, in any of its various incarnations. This template will categorize articles that include it into the "Teen Titans members" category.
The Changeling originally worked for the villainous organization Factor Three and was second in command under the "Mutant Master". Following that group's defeat, he betrayed the Mutant Master upon learning he was really an alien intending to wipe out mankind, normals and mutants alike, and later came to Professor Xavier to reveal he was dying from cancer and only had a few months to live. . Unbeknownst to the X-Men, he was recruited by Professor X as a stand-in while he isolated himself to prepare for his fight against the Z'Nox. The Changeling, masquerading as Professor X, was killed in battle against Grotesk . Only Marvel Girl knew of his deception, and she was sworn not to tell her teammates. Changeling was buried by the X-Men still wearing Xavier's form. It was not until their fight agains the Z'nox that the X-Men learned it had not been the Professor who had died but instead, the Changeling.
Years later the voodoo master Black Talon would bring him back to life as a zombie, one of the undead mutant group that Talon dubbed the X-Humed. Talon sent them to battle the She-Hulk. Even when undead, Changeling was unwilling to have his sacrifice sullied, so he resisted the Talon's control, taking on the form of Elvis Presley to provide She-Hulk with a distraction at a vital moment. Failing to be a worthy zombie, he was returned to the grave.
Changeling is a mutant with the ability to alter his physical appearance at will to resemble that of any person he chooses. He also has limited telepathic abilities which (in the original timeline) were enhanced by Professor X. As a side effect he also gained limited telekinetic abilities.
Changeling has two meanings:
