"Avatars" are characters displayed as a user's alter ego in online games and other virtual spaces. In VRoid Studio and VRoid Hub, the term is used to indicate devices (characters, models, 3D models) that are given a personality by an individual, who plays as an avatar.
With VRoid Hub, you can change the usage conditions so that not only you but also other people can give a personality to the avatars you created. For example, you can allow other users to assign voices and actions to an avatar you created and to publish that avatar on various services.
Avatars have a more distinct personality compared to characters and models.
