How do I delete my avatar?

hey Alice! If the avatar that pops up when you link your account places is not yours, you may want to consider reaching out to the support team to make sure there isn't a glitch in your profile link. Also, your gamer picture that links to the account is
not based on your "current" avatar, it's based on a previous gamer picture that was created. It can even go back to the picture that was used on the 360 consoles years ago. Either way, you can just select a random photo from the list of available default gamer
pictures. Check the link below. it's a how-to for updating your info and gamerpics. Take care!

Hey, Matty! For example, when I link my gamertag to my Rockstar Social Club to play GTA V online, the avatar shown isn't my own. Yet, based on friends' accounts, it's supposed to be my avatar. When I first created my account, I just used the first avatar
that popped up. I think that's the avatar being used. I won't have anything from 360 -- I came directly to the Xbox One from the PlayStation 4.

Do you know how I just delete my avatar altogether?

You can't as far as i know.

You could try starting up Destination Arcade so that it shows up in your achievement history list and then deleting it from there. For games, this typically removes the game from both lists.

If you are on the Xbox One, all you can do is create a new avatar, by launching the app, select settings, and create a new avatar.

If you are on the Xbox 360, then the best way is to launch the Xbox Original Avatar app on Windows 10, and select settings and create a new avatar.
