Visit the Digimon "Make a 3D Avatar" website (see Resources).
Register an account. A series of buttons appear on Disney XD, such as "Home," "Players," "Games," etc. Click "Register Now" to register an account to make an avatar in Digimon.
Enter the information needed to complete the registration process. The name you choose for your Digimon needs approval before you can use it, however, if you have a temporary guest name, you can still make an avatar. Disney XD does not say when your Digimon name is approved.
Click "Avatar" on the "Disney XD" interface. Click "My Items" tab on the right side. You can customize your Digimon avatar. You can choose the face, eyewear, shoes, clothes, and hair for your avatar. Click "Save Headshot" to apply the changes to the avatar.
