Shapeshifter

Shapeshifter is a creature type describing a loosely-defined group of beings capable of assuming other shapes and forms, often imitating other beings. They can be found in all colors of mana, but predominately in blue. The first creature to bear the type was <c>Unstable Shapeshifter</c> in Tempest. <c>Vesuvan Doppelganger</c> and <c>Clone</c> from Alpha, and <c>Shapeshifter</c> from Antiquities were later issued errata to become Shapeshifters, as well.
==Storyline==
===Dominaria===
====Terisiare====
 are mysterious beings that appeared on Terisiare during the Ice Age. Gerda Äagesdotter is supposed to have studied them.
====Vesuva====
The doppelgangers and shapeshifters of the isle of Vesuva are as mysterious as they are notorious. The magical doubles of visitors to the island have to tread cautiously as their doubles are murderously envious of the "originals."
===Innistrad===
Innistrad is home to various shapeshifters (like the <c>Evil Twin</c> and the <c>Identity Thief</c>) whose prime targets are humans. They assume their form to mix into human society, often with malicious purposes.
===Ixalan===
 can be found among the pirates of the Brazen Coalition, although it is unknown if any pirates are actively aware of their presence.
They were likely natives of Torrezon displaced by the ascent of the Legion of Dusk.
===Kaldheim===
The shapeshifters of Kaldheim live in the realm of Littjara. They wear intricately carved wooden masks to hide their true form. They can take any form necessary to blend into their surroundings — including a shifting aurora form that enables them to move freely through the Cosmos — but they tend to prefer animal forms.
Green-aligned shapeshifters, known as Gladewalkers, prefer the forms of wild beasts over any humanoid identity. Bears are a favorite form, but any stag, lynx, bird, or squirrel spotted in the woodlands could be a Gladewalker in disguise. Covewalkers, the blue-aligned shapeshifters, are fascinated with water. They often take on the form of marine animals such as seals or dolphins. They also frequently adopt the identities of mariners, seafaring raiders, fishers, lighthouse keepers, and other humanoids who dwell on or near the waters.
Many believe that shapeshifters are formed from the same stuff as the Cosmos itself—pure shifting light and celestial energy. Whether or not that is their true nature, they can adopt a form similar to the auroras of the Cosmos to travel between realms. Curious and adaptable, they often spend only a few years of a brief childhood in Littjara before venturing out into the Cosmos to see and learn about other realms. Many shapeshifters spend almost their entire lives among other races until at last they return to Littjara for the last years of their lives and end their existence submerged and subsumed into Pentafjord Lake.
===Kamigawa===
On Kamigawa, are spirits of the Kakuriyo who manifest in the physical world bearing the shape of whatever is nearby.
===Lorwyn-Shadowmoor===
====Changelings====
right|thumb|Shapeshifter Token
Lorwyn's shapeshifters are known as changelings. They are a race of relatively harmless, semi-intelligent humanoids who involuntarily change their shape into that of the creatures around them.(2007). Lorwyn Player's Guide. Wizards of the Coast. A changeling's standard appearance is that of a squat, greenish-blue humanoid with slightly scaly skin, large eyes, a translucent body, and frequently a forked tail.
Changelings have no culture per se. They don't have technology or art. When they speak, it's incoherent parroting. They are creatures of high magic, but they don't have the intellectual wherewithal to forge an agenda as a race. There are no notable changeling individuals; they are indistinguishable from each other by anyone other than themselves.
Changelings are skilled at mimicry, but they're far from devious or deceptive. Changelings are obvious. No matter what shape a changeling takes, it always has its characteristic opalescent sheen and its translucent look to it. They can't use their transformation abilities to their advantage, because they automatically adapt to whatever forms are near them. Changelings do not substitute themselves for the children of other races, but a faerie or boggart might pull such a prank on an unsuspecting kithkin mother at times.
Changelings can be found all over Lorwyn, in every kind of terrain. They have no proper homeland, but they are associated with a mysterious cavern called Velis Vel, where they convene each year, and new changelings are created.
====Mimics====
After the Great Aurora, the changelings were transformed into Shadowmoor's mimics, aggressive and vicious creatures that attack in packs while taking forms that resemble warped reflections of their victims.
====Pucas====
Active only in Shadowmoor, pucas are horse-headed shapeshifters whose moods swing wildly from mischief to malice. They use their shapeshifting abilities to hide in plain sight, then strike when their quarry's guard is down.(2008). Eventide Player's Guide. Wizards of the Coast. It's said that a puca hates its reflection, so some Elves carry mirrored daggers when in puca territory. They are amphibious and are particularly common near flooded swamps, mountain streams, and waterfalls.
===Mirrodin===
Mechanical duplicants are common across the face of Mirrodin, taking the form of the or .
===Rath===
Volrath's many experiments on Rath bore many results that took after their master.
===Ravnica===
====Lupuls====
Lupul is a name derived from the Old Ravi word for "lurker". Found solely in Ravnica, Lupuls are shapeshifters that follow the vampire Szadek.Cory J. Herndon (2005). Ravnica Cycle, Book I: Ravnica, Wizards of the Coast In their natural forms, they have the form of a mass of blue-white worms that can move as a single creature with surprising speed and dexterity <c>Mindleech Mass</c>. In this form, they are similar to insects and as such those akin to the bugs can communicate with them and to some extent control them, one such example is Jarad the devkarin hunter. They shapeshift by consuming others, and once they have consumed a living thing in its natural form, they can later change into that creature's form whenever they choose. Lupuls are extremely stealthy and nearly impossible to catch.
Thought to have been defeated centuries before the Decamillennial, they resurfaced under Szadek's commands, until his control was disrupted by Jarad. 
====Humanoids====
Though much harder to tell their natural shape, Dimir agents such as the <c>Dimir Doppelganger</c> or Lazav use their constantly shifting physiology to infiltrate places and organizations.
==Universes Beyond==
The Zygons from Doctor Who is an alien race of humanoid shapeshifters. In their natural state, they are solidly built humanoids with large, cone-shaped heads. Their heads, arms, and torsos are covered in suckers, and they had deeply inset faces. They have the natural ability to shapeshift into other humanoid races.
