The avatar is the person (presumably human) controlled by the player or user. It is two blocks high and can jump one block high. It can interact in the world by destroying things with a pickaxe, building things, painting things, and setting things on fire. There is no image of it and you can't see any part of it. The avatar invincible and indestructible. The player uses the user interface to control the avatar. It is the only character the player can use. It can interact with creatures and some blocks. If the player makes the avatar do things like breaking blocks or entering a certain area, sound and ambient noise occur. The Avatar cannot be seen by the user, therefore it is not customizable.
