-Grimm Title: Doppelganger

-Powers: The Doppelganger's most notable feature is it's shapeshifting capabilities. It is capable of completely changing it's shape in a matter of days, hours or even minutes depending on how big the change is. They most-frequently pretend to be animals, but there are reports of some that shift into plant-like or even human-like forms. It can even disguise himself as other Grimm.

It's shapeshifting ability even includes the "bone plates", which can both "crack" into multiple pieces and be spread out over their body, be "put together" into various shapes, or even be shed out, though it is unknown (and doubted) if it can shed out it's mask as well.

-Environment: North-West Sanus

-Appearance: Variable, though it always maintains the "Black body and red eyes with yellow iris" aesthetic. Reportedly, it seems to follow Conservation of Mass in regards to it's shapeshifting, meaning it's proportions have min. and max. limits.

-Armouring(s): Variable. It's been noted to not be as strong as most other Grimm.

-Aesthetics: When the mask is "put together", the markings resemble an asterisk, with the eyes in the top 2 internal angles. The shape varies but it's generally oval.

-Behaviour: They are generally loners, but small packs of doppelgangers disguised as the same creature are not rare either. They generally behave similarly to said creature, until they find prey, at which point they observe them quietly from afar for long periods of time before attacking.

-Attack(s): The exact method of attacking varies, though it's purely physical; it can't, say, imitate a Sea Dragon's lightning beams. It also cannot imitate things like poison.

-Strengths: It's exact strength varies based on it's current form, though compared to other Grimm they aren't particularly strong. They are, however, very resistant to blunt hits.

Their observational behaviour also makes them capable of easily imitating other creatures in combat, including humans and faunus. Though due to lack of Aura, it would never compare to the average huntsman.

-Weakness(es): When they receive a strong-enough blunt impact, their body seems to momentarily deform before recovering it's shape. Aside from how this reveals what they are, Doppelgangers seem to be stunned while recovering.

If a part of their body is frozen or petrified (or similar), it cannot shapeshift that body part.

-Additional Notes: Most Doppelgangers seem capable of only turning into solid things, though bigger, older ones have been noted to shift into less-solid states, like slimes. There are no known cases of one turning fully into a liquid, however.

Due to their shapeshifting nature, some villages have rumors of Doppelgangers killing people and taking their place. These rumors aren't particularly widespread however, since the amount of paranoia they cause easily attracts Grimm to those villages.
