You can choose your hero name for the first time after finishing the game's tutorial missions. After that, you are able to rename yourself one more time. Unfortunately, it is not possible to change your name again a third time, so please choose your name carefully.
To use your one-time rename, please go to the options menu, and tap on 'Change name'.
The name of your Alliance cannot not be changed once it is set when founding it.
We are sorry to let you know that we unfortunately cannot offer additional name changes for your hero or Alliance.
