A virtual representation of an entity, generally a person. Avatars could be single images, two-dimensional characters, nonhuman beings, tridimensional embodiment, or a mix of digital elements and an edited physical image. This digital embodiment generally serves as interface for communication between people, and occurs as a representation of one's social presence online and chosen identity form.
Unlike the human physical form which relies on biological limitations and genetic factors, an avatar could be created and easily altered by its creator. Such digital choices and alterations range from natural adjustments, such as gender flexibility, hair color, different body proportions to nonhuman features like an unusual number of limbs or mouths, none of which has to match a person's physical embodiment. As avatars could be shape-shifted across media types, an individual could choose to have multiple representations, depending on mood or platform.
