Change Roblox username or Roblox display name When you initially sign up to play Roblox, you must give your Roblox account a Roblox username. Other players will see your Roblox name in game.

In the Settings menu, navigate to and click on the "Account Info" tab. Find and click on the "Change Username" button. Enter your desired One Piece-inspired username and then your Roblox password.
