Avatars are profile pictures available for use by players. They appear in the multiplayer aspect of the game, such as Arena mode, Guilds, and Leaderboards. You are required to select an avatar when participating in a multiplayer activity for the first time. There is no option to change your avatar once it has been selected so you will have to stick to your chosen avatar for your own profile. The Grand Master of a guild gets a golden frame around their avatar in the guild interface to identify them as such.
