Classification: Shapeshifting Entity.

Appearance: While in their original form, the Changelings appear as a golden brown viscous liquid.

Lifespan: Unknown.

Unique Abilities: Changelings have the ability to change their biomolecular structure to mimic anything. The only compromising aspect of this skill is the inability to hold a shape over 16 hours. Changelings must revert to their liquid state or endure a painful "decomposition". They are capable of merging with each other when in their liquid state. They call this process the "Great Link", and it allows them to achieve a considerable degree of information and memory sharing while increasing their ability to modify their own internal structure.

Personality Traits: The Changelings treat the species under their protection relatively well, although they are extremely strict and do not toleratre failure. Changelings are diplomatic and have a commanding presence.

Government: There is no hierarchy of power within their society: no single Changeling is superior to others except inherent differences in skill and knowledge. Equality and peace reigns within their society. They take pride in having never inflicted harm upon one of their own, however much damage they wrought offworld.

Organization: Enemy of the United Federation of Planets.
