You can only change your username once.

Where you submit your request to change your username it says "Changing your username is possible on Wikia, but only once, so be sure you want to change it before you submit a request. This process cannot be reversed, and once we change your username, we cannot change it again. Please make sure you have fully read this help page before sending in a request:http://help.wikia.com/wiki/Help:Changing_your_username"
