Human form

Several Digimon have the ability to take on a human form (人間形態), or, in some cases, an animal form. This is usually done to avoid detection while in the Human World, and generally hinders their combat abilities.

Possession of a human form is usually a character trait, rather than a species-wide ability, although there are exceptions.
